Abstract Background Transient hypotension is a common occurrence during the implantation of bone cement. This placebo-controlled randomized clinical trial study investigated the effect of prophylactic infusion of norepinephrine on the incidence of hypotension in senior patients who underwent vertebroplasty. Methods The trial recruited patients who were greater than or equal to 65 years of age, had an American Society of Anesthesiologist physical status classification of I to III, and underwent vertebroplasty from August 2020 to August 2021 at the Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine in China. The patients were randomly grouped according to whether they received either a norepinephrine infusion of 0.05 µg/kg/min or an equivalent volume of saline 10 min before implantation of bone cement. Intraoperative hemodynamics were monitored continuously by the MostCare system at the following 7 time points: 10 min before implantation of bone cement and immediately, 30 s, 1, 3, 5, and 10 min after implantation of bone cement. We also recorded the number of hypotensive episodes and the total number of vasopressors after implantation of bone cement. Multivariable logistic regression was used to assess the risk factors associated with hypotension after implantation of bone cement. Results A total of 63 patients were randomized to the control group (n = 31; median [IQR] age, 74 [69–79] years) and the norepinephrine group (n = 32; median [IQR] age, 75 [71–79] years). The incidence of hypotension in the norepinephrine group was significantly lower than that in the control group after implantation of bone cement (12.5% vs. 45.2%; relative risk [RR], 3.61 [95% CI, 1.13–15.07]; P = 0.005). Moreover, the median (IQR) number of hypotensive episodes (0 [0–0] vs. 0 [0–2]; P = 0.005) and the total number of vasopressors (0 [0–0] vs. 0 [0–1]; P = 0.004) in the norepinephrine group were significantly lower than those in the control group. Furthermore, compared with the baseline, the MAP significantly decreased at 1 min (P = 0.007) and 3 min (P

Abstract Background This study aimed to investigate a technique for treating pediatric popliteal cysts with a triple-channel knee arthroscopic approach, hypothesizing that this technique exhibits favorable clinical outcomes with reduced recurrence rates. Methods A retrospective analysis was conducted on the clinical data of 14 patients with symptomatic pediatric popliteal cysts admitted to the joint surgery center using an arthroscopic minimally invasive technique from December 2017 to December 2020. Arthroscopy was employed for adequate enlargement of the posterior medial flap opening between the cyst and the joint cavity and to completely resect the cyst wall. The popliteal cyst recurrence was assessed through Magnetic Resonance Imaging(MRI) at 3 and 12 months post-surgery, and the Rauschning and Lindgren scores were recorded to evaluate the clinical prognosis. Results A total of 14 children completed the follow-up, including 8 boys and 6 girls, with a mean age of 9.9 ± 1.1 years (5–12 years); 5 cases in the left knee and 9 cases in the right knee; the mean operative time was 19.2 ± 2.7 min (10–25 min); and the mean follow-up time was 15.1 ± 2.4 months (12–24 months). There was no intraoperative vascular or nerve injury and no incisional exudate infection. Postoperatively, posterior knee symptoms disappeared in the children, Rauschning and Lindgren scores significantly improved, and no recurrence signs were observed on MRI. Conclusions This study determined that the arthroscopic three-channel minimally invasive technique is effective and safe for treating popliteal cysts in children, making it worthy of clinical promotion.

Abstract Purpose Retraction of the hepatic left lateral segment (HLLS) is a crucial maneuver for surgical field exposure during laparoscopic gastrectomy with systematic lymphadenectomy. Though various methods of retraction are available, there is no perfect solution. Here, we report the results of our initial 42 cases with HLLS inversion method and discuss the feasibility, safety, effectiveness and technical aspects of this method. Methods The intraoperative and postoperative short-term outcomes of 42 patients who underwent HLLS inversion during laparoscopic total gastrectomy and proximal gastrectomy in our department September, 2023 to January, 2024 were reviewed. HLLS inversion was performed by mobilizing the HLLS and inverting it to the right supra-hepatic space through an incision at the falciform ligament. Results 42 patients underwent HLLS inversion successfully with an average time of 13.9 min. 7 patients needed re-inversion due to slipping back of the HLLS during operation. Optimal exposure of the surgical field was achieved in all patients. No intra-operative complications occurred, except for 1 patient presented with mild intraoperative hepatic hemorrhage requiring electrocoagulation for hemostasis. Alanine aminotransferase and glutamine aminotransferase elevated in some patients on postoperative day 1(POD1), but declined to preoperative levels on the 7th postoperative day. There were no Clavien-Dindo II grade or higher digestive complications after surgery. In 5 patients with preservation the hepatic branch of the vagus nerve, the contractile function of the gall bladder was intact or slightly impaired 2 weeks after operation. Conclusion For laparoscopic proximal gastrectomy (LPG) and laparoscopic total gastrectomy (LTG), HLLS inversion is a feasible method for optimizing visualization of the surgical field with preservation of the function of the hepatic branch of the vagus nerve. It is safe and acceptable as to the manipulation time. Re-inversion is easy and effective even in case of failure of inversion. HLLS inversion seems to be a promising technique for retraction of the liver during laparoscopic gastrectomy.

Abstract Introduction Abdominal surgical emergencies have a high mortality rate. Effective management primarily relies on the early identification of patients at high risk of postoperative complications. The objective of our study was to determine the prognostic factors associated with poor outcomes from abdominal surgical emergencies in Senegal and to establish a predictive score for mortality for preoperative risk evaluation (NDAR (New Death Assessment Risk) score). Methodology This was a retrospective national cross-sectional study conducted over one year in 14 regions of Senegal. Adult patients (aged > 15 years) who presented with a traumatic or non-traumatic abdominal surgical emergency were included. The studied variables included clinical and paraclinical data. The variable of interest was death within 30 days of the surgery. Logistic regression was used to identify the factors independently associated with mortality. Risk factors identified after logistic regression analysis were weighted using odds ratio (OR) values rounded to the nearest whole number. The predictive capacity of the score was evaluated by analyzing the ROC (Receiver Operating Characteristic) curve based on the area under the curve (AUC). Results A total of 1114 patient records were included, with a mortality rate of 4.4%. Diagnoses were observed in patients included appendicitis in 39.8% of cases (n = 444), followed by peritonitis in 22.3% (n = 249), intestinal obstruction in 18.5% (n = 205), strangulated hernias in 10.5% (n = 117), and abdominal trauma in 6.1%. Logistic regression, established the following scores: age > 40 years (score 2), ASA status grade 2 or higher (score 1), presence of a positive QSIRS score (score 2), diagnosis of peritonitis (score 2), diagnosis of intestinal obstruction (score 1), and the presence of intestinal necrosis (score 3). The score is positive if the total is strictly greater than 5, indicating a 17.7% risk of mortality. This score had a high predictive capacity with an AUC of 0.7397. Conclusion This study enabled the establishment of a score that allows for the early identification of at-risk patients, even in constrained resource settings, facilitating appropriate perioperative management and timely surgical intervention to reduce the risk of complications. This approach, focused on early recognition of high-risk patients, is crucial for improving clinical outcomes in abdominal surgical emergencies.

Abstract Background Resection of intrathoracic tumor with cardiopulmonary bypass (CPB) remains a relatively under-reported intervention in literature, and its role in managing locally advanced mediastinal and lung cancers is a topic of ongoing debate. Our aim was to review our experience and assess the role of CPB for treating locally advanced mediastinal and lung cancers. Methods Between 2015 and 2020, this study initially included 10 patients with primary locally advanced thoracic malignancies with apparent adjacent cardiovascular invasion demonstrated by thoracic imaging scans. Operation was performed based on a multidisciplinary tumor board consensus. Eventually, 8 patients (3 primary lung cancers and 5 mediastinal cancers) received either salvage or elective resection with CPB; two completed surgery without requiring CPB. Results Regarding the extent of adjacent structure involvement, 4 patients presented with involvement of the superior vena cava (SVC), 1 involved the right atrium (RA), 2 involved the SVC and RA, and 1 involved the SVC, the origin of main pulmonary artery, and the ascending aorta. Thirty-day mortality occurred in two of three patients receiving salvage surgery due to respiratory insufficiency. With the long-term follow-up, one patient died of recurrence 25 months postoperatively, one survived with recurrence 30 months postoperatively, and four were alive without recurrence for 35, 36, 49, and 107 months after operations. Conclusion In certain patients, particularly for elective surgical candidates rather than salvage resection, CPB allows for extended resection of locally advanced thoracic cancers with acceptable perioperative safety and survival.

Abstract Background The study aimed to compare the clinical outcomes of robotic right colectomy (RRC) versus laparoscopic right colectomy (LRC) in patients diagnosed with right colon cancer, given the increasing adoption of robotic surgical techniques and their potential benefits in oncologic surgery. Methods This retrospective comparative study included patients who underwent right colectomy at Sir Run Run Shaw Hospital, College of Medicine, Zhejiang University, between January 2019 and May 2022. The primary outcomes measured were the number of lymph nodes harvested. Key secondary outcomes included the operation time, intraoperative blood loss, postoperative complications, hospitalization costs, overall survival (OS), and disease-free survival (DFS). Data were analyzed using multivariable Cox proportional hazards regression to adjust for potential confounders. Results A total of 225 patients (aged 65.23 ± 11.45, 108 males) with right colon cancer were included, with 100 (44.4%) patients underwent RRC. Patients who underwent RRC had significantly more lymph nodes harvested (27.69 ± 12.59 vs. 24.43 ± 9.42, P = 0.028), and incurred higher total hospitalization costs compared to those with LRC (9.68 ± 7.12 vs. 5.28 ± 1.23 ten-thousand-yuan, P 0.05) within a median follow-up of 27 (range, 9–44) months. Multivariable cox proportional hazards regression showed that patients underwent RRC had significantly higher risk for all-cause death compared with those underwent LRC [hazards ratio (HR) = 2.303, 95% confidence intervals (CI): 1.625–3.265, P

Abstract Background Totally implantable venous access devices (TIVADs) have been widely used for many years in the management of cancer patients. However, previous studies have rarely focused on the period surrounding TIVAD removal, which is a critically important phase for these devices. This study aims to address this gap by investigating the surgical approaches, timing, and associated complications related to the removal of TIVADs, thereby enhancing the management of these devices. Method A retrospective analysis was conducted on a cohort of 4,954 TIVAD extraction procedures performed at the Breast Center of the Fourth Hospital of Hebei Medical University between January 1, 2016, and August 1, 2023. Results Among 4,954 cases, the indwelling time of TIVADs for included patients ranged from 2 to 60 months. 4,882(98.5%) cases removed their TIVADs after completion of cancer treatment, while 72 cases (1.5%) were unplanned removal due to TIVADs related complications. Two surgical techniques were observed for port removal: in 20% of cases, the injection port was removed first, followed by the catheter; in 80% of cases, the catheter was removed first, followed by the injection port. Complications during TIVADs removal were observed in 13 cases (0.3%) including 2 cases of bleeding, 5 cases difficulty in removal of the port and catheter, and 6 cases representing of delayed wound healing. Longer indwelling time tended to have higher risk of developing catheter rupture and fracture. Conclusion This study provides valuable insights into the removal of TIVADs in cancer patients. Complications during removal were uncommon but included bleeding, difficulty in removing the port and catheter, and delayed wound healing. Additionally, longer indwelling times were associated with an increased risk of catheter rupture and fracture, highlighting the need for careful monitoring and timely removal of TIVADs to minimize potential complications. The findings of the study underscore the importance of optimizing TIVAD management, particularly during the removal phase, to improve patient outcomes.

Abstract Background The objective of this study is to organise data on complications following total hip replacement (THA) over a span of 10 years, specifically focussing on cases that necessitated revision endoprosthetic surgeries. The objective is to create a recommendation for an All-Ukrainian registry of initial and repeated hip arthroplasty (HA) and standardise the terminology used to define “revision of total hip replacement surgery”. Methods The retrospective analysis examined 236 instances of revision hip arthroplasty (rTHA) performed at the Institute of Traumatology and Orthopaedics Centre between January 2005 and December 2021. The primary factors for revision were identified through an analysis of the patient’s medical records, laboratory results, visual inspection, and the state of the previously implanted prosthesis. Demographic information, primary and revision HA dates, diagnoses, and causes of complications were recorded. The statistical analysis was conducted using the Statistica package (StatSoft), version 12.6 (2015), with a significance level of p

Abstract Background Early laparoscopic cholecystectomy (ELC) in the setting of acute calculous cholecystitis (ACC) requires to be performed by highly-skilled surgeons to avoid complications. The purpose of this study is to identify preoperative factors that would predict difficult ELC among patients with ACC prior to proceeding with surgery. Methods We retrospectively reviewed all patients who received ELC within 10 days from the onset of symptoms of ACC between August 1, 2018, and December 31, 2022. They were divided into 2 groups according to the difficulty of surgery. Results 149 patients with ACC received ELC during the study period. ELC was considered difficult in 52 patients (35%). Five preoperative factors were identified as significant predictors of difficult ELC (DELC) on multivariate analysis: duration of acute attack ≥ 4 days from the onset of symptoms till surgery (OR 34.4, P 20 mm (OR 20.2, P = 0.029), ultrasound showing gallstone impaction in Hartmann’s pouch (OR 7.2, P = 0.017), history of prior episode(s) of acute attack (OR 6.8, P = 0.048), and diabetes mellitus (OR 5.8, P = 0.046). Conclusion Careful preoperative assessment of patients with ACC is crucial among junior surgeons with limited surgical expertise prior to proceeding with ELC to identify those at risk of DELC to potentially reduce postoperative morbidity and mortality. If encountered, a management plan should be made, and surgery should proceed only upon confirming the availability of experienced surgeons in the field of biliary and laparoscopic surgery to supervise or assist in the procedure. Alternatively, such group of patients should rather be transferred to more advanced surgical centers which offer higher level of care to maintain patient safety and optimal surgical outcomes. More importantly, bail-out procedures should always be resorted to whenever DELC is encountered intraoperatively to prevent further surgical damage.

Abstract Background To potentially lessen injuries and associated complications, fluorescence cholangiography has been suggested as a technique for enhancing the visualization and identification of extrahepatic biliary anatomy. The most popular way to administer indocyanine green (ICG) is intravenously, as there is currently little data on ICG injections directly into the gallbladder. In order to visualize extrahepatic biliary anatomy during laparoscopic cholecystectomy (LC), we compared the two different ICG administration techniques. We also examined variations in visualization time, as well as the effectiveness, benefits, and drawbacks of each modality. Methods In this prospective randomized clinical study, 60 consecutive adult patients with chronic and acute gallbladder disease were included. Our study conducted from 2022 to 2024 in Surgical Department of Theodor Bilharz Research Institute. Thirty patients underwent LC with intravenous ICG administration (IV-ICG), thirty patients received a direct injection of gallbladder through transhepatic ICG (IC-ICG) and Preoperative, intraoperative, and postoperative patient data were examined. Results In terms of their perioperative and demographic features, the groups were similar. Without a statistically significant difference, the IV-ICG group’s total operating time was less than that of the IC-ICG group (p 0.140). Compared to the transhepatic IC-ICG method, IV-ICG was more accurate in identifying the duodenum and the common hepatic duct (p = 0.029 and p = 0.016, respectively). In the transhepatic IC-ICG and IV-ICG groups, the cystic duct could be identified prior to dissection in 66.6% and 73.3% of cases, respectively, and this increased to 86.6% and 93.3% following dissection. In the transhepatic IC-ICG group, the common bile duct was visible in 93.3% of cases; in the IV-ICG group, it was visible in 90% of cases. Two cases in the IC-ICG group and every case following IV-ICG administration had liver fluorescence (6.6% versus 100%; p

Abstract Background Robot-assisted surgery (RAS) is being performed with increasing frequency in pediatric oncology. We report our experience with RAS for renal tumors in children and compare the outcomes between RAS and laparoscopic surgery (LAS). Methods A total of 23 patients with renal tumor who underwent minimally invasive surgery (MIS) between January 2020 and December 2023 were included in the study. The inclusion criteria enrolled in this study was unilateral tumors with maximum tumor diameter less than 10 cm. Patients who had enlarged lymph node, venous thrombosis, preoperative tumor rupture, bilateral renal tumor, or extrarenal extension on imaging were deemed contraindications and excluded. Patient demographics, operative details, postoperative outcomes and follow-up were recorded. Results Among these patients, 17 underwent RAS and 6 underwent LAS. In the RAS group, the median age was 64 months (range, 9–156) with a median weight of 19.48 kg (range, 8.4–46.5); the maximum tumor diameter at operation was 55.65 mm (range, 22–88); the operation time was 188.8 min (range, 120–210), the intraoperative blood loss was 20 ml (range, 5–50), and the length of postoperative hospital stay was 4 days (range 1–9). There was no significant difference in patients’ age, weight, location, tumor size, histological pattern and operation time between the two groups (P > 0.05). The RAS group had a significantly less intraoperative blood loss (P = 0.026) and less length of postoperative stay (P = 0.01) than the LAS group. Conclusion Our initial experience suggested that RAS in pediatric renal tumor was feasible and safe, and it reduced surgical trauma and accelerate postoperative recovery for the patients. Due to the limitations of sample size and study quality, the clinical importance of these findings still needs to be further verified.

Abstract Background In recent years, the incidence of pelvic fractures has been on the rise, predominantly affecting the elderly population. Deep vein thrombosis may lead to poor prognosis in patients. monocyte-to-lymphocyte ratio is novel biomarkers of inflammation, and this study aims to verify their predictive effect and construct the nomogram model. Method This study used binary logistic regression analysis to predict the predictive effect of MLR on the occurrence of DVT in pelvic fractures patients. And use R studio to construct nomogram model. Result The results showed that Age (1.04 [1.01, 1.07], p = 0.006), WBC (1.44 [1.28, 1.61], p

Abstract Background Coronary artery bypass grafting (CABG) is often performed with hypothermic cardiopulmonary bypass (CPB) to reduce metabolic demands and protect the myocardium. However, hypothermia can increase bleeding risks and other complications. Methods This is a prospective, multi-center, randomized controlled trial. From September 2023 to December 2024, a total of 336 eligible patients planning to undergo on-pump CABG will be enrolled. All participants will be randomly divided into mild hypothermia CPB group (target oxygenator arterial outlet blood temperature at 32–33℃) or normothermia CPB group (target oxygenator arterial outlet blood temperature at 35–36℃). The primary endpoint is Universal Definition of Perioperative Bleeding (UDPB) class 2–4. Secondary endpoints are class of UDPB, levels of coagulation and inflammatory factors, in-hospital mortality, perioperative related complications, ICU length of stay, and hospital length of stay. Discussion This clinical trial aims to compare the effects of different target temperature during CPB on postoperative bleeding and to explore optimal temperature strategy to provide new clinical evidence. Trial registration Chictr.org.cn : ChiCTR2300075405. The trial was prospectively registered on 4 September 2023.

Abstract Background Post-traumatic headache is a disabling secondary headache disorder often attributed to traumatic brain injury and affects millions of individuals worldwide. Few studies have been done on the treatment needs of these patients in emergency departments. The purpose was to compare the effectiveness of ketorolac intravenous versus acetaminophen intravenous in reducing headaches in patients following head trauma. Methods This was a semi-experimental study in which the participants were assigned two groups. In the acetaminophen intravenous group, 1 g acetaminophen and in the ketorolac intravenous group, 60 mg of this drug was injected. Statistical analysis was done with IBM SPSS statistical software version 21, and a P-value less than 0.05 was considered statistically significant. Results Among samples after 6 h from the injection, the pain score in the ketorolac intravenous group was less than the acetaminophen intravenous group (P = 0.006). Also, the pain reduction rate in the ketorolac intravenous group was more than the acetaminophen intravenous group from before the injection until 2 h after it (P = 0.01) and before injection until 6 h after it (P = 0.001). The frequency of drowsiness in 2 and 6 h after drug administration in the ketorolac intravenous group was lower than the acetaminophen intravenous group, which is significant in 2 h after drug administration (P = 0.038). The verbal analog scale score comparison for two groups 2 h before medicine administration with pain control score (P = 0.03) and 6 h with pethidine use control (P = 0.003) is significant. Conclusions According to this study, ketorolac’s intravenous effect on pain control is better than that of acetaminophen intravenous. With more samples, we can express the survey results more decisively in the future.

Abstract Objective Poly (ADP-ribose) polymerase (PARP) inhibitors such as olaparib and niraparib have shown promise in extending progression-free survival (PFS) in patients with platinum-sensitive recurrent (PSR) epithelial ovarian cancer. In this retrospective study, we aimed to present our own data on the effect of PARP inhibitors on PFS in recurrent epithelial ovarian cancer. Methods 82 patients diagnosed with PSR epithelial ovarian, tubal, or primary peritoneal cancer between May 2017 and September 2023 were initially enrolled from our hospital. However, 16 patients had prior exposure to PARP inhibitors during primary treatment, and 11 were lost to follow-up. Consequently, the study focused on 55 eligible patients. PFS was compared between patients receiving PARP inhibitor maintenance therapy and those who did not. Results Among the 55 patients with PSR epithelial ovarian cancer, 18 received olaparib as maintenance therapy, 19 received niraparib, and 18 opted for observation. PARP inhibitor therapy significantly extended PFS (mean 24.0 months) compared to observation (mean 9.0 months, p = 0.0005), regardless of BRCA mutation status (HR = 0.20, 95% CI: 0.08–0.50). Subgroup analysis showed no statistical difference between olaparib and niraparib. Additionally, there was no PFS difference based on BRCA mutation status within both PARP inhibitor groups. Conclusion Our retrospective study demonstrates that PARP inhibitor maintenance therapy, including olaparib and niraparib, significantly prolongs PFS in patients with PSR epithelial ovarian, tubal, or primary peritoneal cancer, These findings support the broad utilization of PARP inhibitors as a standard maintenance therapy for PSR epithelial ovarian cancer irrespective of BRCA mutation status.

Abstract Thyroid cancer (TC) represents one of the most prevalent endocrine malignancies, with a rising incidence worldwide. Epigenetic alterations, which modify gene expression without altering the underlying DNA sequence, have garnered significant attention in recent years. Increasing evidence underscores the pivotal role of epigenetic modifications, including DNA methylation, RNA methylation, and histone methylation, in the pathogenesis of TC. This review provides a comprehensive overview of these reversible and environmentally influenced epigenetic modifications, highlighting their molecular mechanisms and functional roles in TC. Additionally, the clinical implications, challenges associated with studying these epigenetic modifications, and potential future research directions are explored. Graphical Abstract

Abstract Study design Retrospective cohort study. Purpose To explore the complications and risk factors for total resection (TR) of primary thoracic and lumbar spinal tumors over the past decade at our institution. Methods Patients meeting inclusion criteria (primary spinal tumors, thoracic or lumbar location, TR at our center) were included. Demographic characteristics, surgical data, perioperative complications and management results were reviewed. Patients were stratified by tumor site, the number of excised segments, and recurrence status to elucidate distinctive characteristics. Results The cohort comprised 103 patients, with a mean age of 35.8 years. On average, 1.83 vertebral segments were resected per patient. Perioperative complications were substantial, totaling 166 events, with 71 classified as major and 95 as minor, yielding an average of 1.61 complications per patient. No perioperative deaths occurred, but 79 patients (76.7%) experienced at least one complication. Multiple vertebral sections correlated with a higher complication rate (P = 0.031), and lumbar surgeries exhibited elevated risks of large vascular injury (P = 0.001), neurological deterioration, and cerebrospinal fluid leakage compared to thoracic cases. Conversely, thoracic spinal procedures showed a higher rate of pleural effusion (P = 0.004). Binary logistics stepwise regression identified multi-segmental resection as the independent risk factor for major perioperative complications. Conclusions TR of primary spinal tumors is associated with a high perioperative complication rate, although most events have a favorable prognosis. Complication characteristics vary based on the surgical site, number of excised segments, and surgical history. A nuanced preoperative evaluating approach considering patient age, surgical segments, and extent of resection is crucial.

Abstract Objective To investigate contralateral central lymph node metastasis (CCLNM) in patients with unilateral papillary thyroid carcinoma (UPTC). To provide a reference for clinical decision-making, a prediction model for the probability of CCLNM was established. Method The clinicopathological data of 221 UPTC patients who underwent surgical treatment were retrospectively analyzed. Univariate and multivariate logistic regression analyses were performed to determine the independent risk factors for CCLNM according to clinicopathological characteristics, construct a prediction model to construct a visual nomogram, and evaluate the model. Results According to univariate and multivariate logistic regression analyses, sex (P = 0.01, OR: 3.790, 95% CI: 1.373–10.465), extrathyroidal tumor extension (ETE) (P = 0.040, OR: 6.364, 95% CI: 1.083–37.381), tumor diameter (P = 0.010, OR: 3.674, 95% CI: 1.372–9.839) and ipsilateral central lymph node metastasis (ICLNM) (P

Abstract Background To investigate the clinicopathologic characteristics, therapeutic methods, and prognosis of secretory carcinoma of salivary gland (SCSG). Methods The clinicopathologic data of 13 patients with SCSG admitted to Shanxi Cancer Hospital from January 2018 to June 2023 were retrospectively analyzed, and a literature review was performed. Results A total of eight males and five females aged 22–78 years old were enrolled, and they commonly presented with painless masses in the parotid or submandibular gland. They all underwent surgical treatment, accompanied by typical pathological examinations postoperatively. Fluorescence in situ hybridization (FISH) was conducted in seven cases, the results were all positive, and no gene fusion other than ETV6-NTRK3 was found. Two patients developed local relapse during follow-up, both of which were in the surgical area. By the end of the follow-up, 12 patients survived and one patient died. Conclusions SCSG is a rare low-grade malignancy with a good prognosis. Pathological and immunohistochemical characteristics are the key to secretory carcinoma (SC) diagnosis, and surgical excision is the major treatment means for SCSG. Whether to perform simultaneous cervical lymph node dissection and other adjuvant therapies should be determined based on the pathological stage and the presence or absence of high-risk factors.

Abstract Nerve tumors in the retroperitoneal space are a rarity. Radical surgery according to soft tissue tumors can lead to persistent pain and neurological deficits. This study aims to evaluate clinical outcomes of patients treated by a visceral- / neurosurgical approach. 33 patients with a retroperitoneal nerve tumor underwent surgery between 01/2002 and 12/2022 at our department. A visceral surgeon provided access to the retroperitoneal space, followed by micro-neurosurgical tumor preparation under neuromonitoring. Clinical examination and MRI were performed 12 weeks after surgery and further 3 months (WHO grade > 1) or 12 months (WHO grade 1). Further examinations were based on MRI findings and residual symptoms with median follow-up time of 24 months. One patient was treated for two distinct masses resulting in a total of 34 histological findings. Schwannomas (n = 15; 44.1%) and neurofibromas (n = 10; 29.4%) were the most common tumors. Long-term improvements were noted in radicular pain (15/18 patients; 83.3%), motor deficits (7/16 patients; 43.8%), abdominal discomfort and pain (5/7 patients; 71.4%). Recurrences were observed in 3/33 (9,1%) patients. This study represents the largest series of retroperitoneal BPNSTs treated with microsurgical techniques. Prospective multicenter studies are warranted to establish standardized treatment guidelines.

Abstract Background The purpose of this systematic review and meta-analysis is to assess the efficacy of various machine learning (ML) techniques in predicting preoperative lymph node metastasis (LNM) in patients diagnosed with papillary thyroid carcinoma (PTC). Although prior studies have investigated the potential of ML in this context, the current evidence is not sufficiently strong. Hence, we undertook a thorough analysis to ascertain the predictive accuracy of different ML models and their practical relevance in predicting preoperative LNM in PTC patients. Materials and methods In our search, we thoroughly examined PubMed, Cochrane Library, Embase, and Web of Science, encompassing their complete database history until December 3rd, 2022. To evaluate the potential bias in the machine learning models documented in the included studies, we employed the Prediction Model Risk of Bias Assessment Tool (PROBAST). Results A total of 107 studies, involving 136,245 patients, were included. Among them, 21,231 patients showed central LNM (CLNM) and 4,637 had lateral LNM (LLNM). The meta-analysis results revealed that the c-index for predicting LNM, CLNM, and LLNM were 0.762 (95% CI: 0.747–0.777), 0.762 (95% CI: 0.747–0.777), and 0.803 (95% CI: 0.773–0.834) in the training set, and 0.773 (95% CI: 0.754–0.791), 0.762 (95% CI: 0.747–0.777), and 0.829 (95% CI: 0.779–0.879) in the validation set, respectively. A total of 134 machine learning-based prediction models were included, covering 10 different types. Logistic Regression (LR) was the most commonly used model, accounting for 81.34% (109/134) of the included models. Conclusions Machine learning methods have shown a certain level of accuracy in predicting preoperative LNM in PTC patients, indicating their potential as a predictive tool. Their use in the clinical management of PTC holds great promise. Among the various ML models investigated, the performance of logistic regression-based nomograms was deemed satisfactory.

Abstract Background This study was to analyze the roles of red blood cell distribution width (RDW), anion gap (AG) levels and their combined effects on the risk of acute kidney injury (AKI) following cardiac surgery. Methods This cohort study extracted the data of 1951 participants aged ≥ 18 years with the assessment of AKI after cardiac surgery during ICU stay from MIMIC-IV database between 2008 and 2019. Receiver operator characteristic (ROC) curve was used to determine the optimal cut-off value AG and RDW. The associations between AG, RDW, and the combined effects of AG and effects were evaluated via univariable and multivariable Logistic models. Odds ratio (OR) with 95% confidence interval (CI) were imputed. Results Among all the participants, 831 participants had AKI, and 1120 did not have AKI. ROC curves revealed that the optimum cut of points of AG and RDW were 12.75 mmol/L, and 13.65%, respectively. Increased risk of AKI was found in patients after cardiac surgery with AG > 12.75 mmol/L (OR = 1.44, 95%CI 1.15–1.80) or RDW > 13.65% group (OR = 1.23, 95%CI 1.01–1.50). In comparison to subjects with AG ≤ 12.75 mmol/L and RDW ≤ 13.65%, AG > 12.75 mmol/L and RDW ≤ 13.65% (OR = 1.42, 95%CI 1.07–1.89), and AG > 12.75 mmol/L and RDW > 13.65% (OR = 1.75, 95%CI 1.24–2.47) were associated with increased odds of AKI in patients after cardiac surgery. Conclusions AG and RDW had combined effects on risk of AKI in patients after cardiac surgery, which might offer an insight for the management of patients after cardiac surgery.

Abstract Background At present, the clinical methods for preventing and treating contrast-induced nephropathy (CIN) are limited, and statins can play a better role during this process. So, we aimed to assess the atorvastatin on renal function in nephropathy patients after percutaneous coronary intervention (PCI). Methods In this work, 100 elderly patients with coronary heart disease (CHD) were selected into an experimental group (Exp group, 50 cases, 40 mg/d po atorvastatin) and a control group (Ctrl group, 50 cases, 10 mg/d po atorvastatin). The renal function indicators, blood routine indicators, and the incidence of adverse reactions (ARs) were compared between patients in Exp and Ctrl groups. Results After surgery, the levels of serum creatinine (SCr), blood urea nitrogen (BUN), cystatin C (CysC), high-sensitivity C-reactive protein (hs-CRP), and interleukin (IL6) in patients in the Exp group were much lower, and the levels of estimated glomerular filtration rate (eGFR) and superoxide dismutase (SOD) were higher (all P 0.05). Compared with conventional doses of atorvastatin, high-dose atorvastatin can effectively prevent renal function damage in patients with CIN, decrease the inflammation and oxidative stress in patients, and will not increase the risk of ARs during hospitalization. Conclusion Taken together, high-dose atorvastatin can be applied in treating patients with CHD after PCI due to its excellent efficacy and high safety.

Abstract Objective This study aims to compare the efficacy of the Age-adjusted Charlson Comorbidity Index (ACCI) and the Elixhauser-Van Walraven Comorbidity Index (ECI-VW) in predicting mortality risk among patients undergoing heart valve surgery. Methods Clinical data were extracted from the INSPIRE Database using R language. The Receiver Operating Characteristic (ROC) Curve was employed to assess the predictive accuracy of ACCI and ECI-VW for in-hospital all-cause mortality and post-surgical all-cause mortality at 7 and 28 days. Subgroup analysis was conducted to validate the application efficacy, and the optimal cutoff value was identified. Results The study included 996 patients, with 931 survivors and 65 cases of in-hospital all-cause mortality. The area under the curve (AUC) for ACCI in predicting in-hospital all-cause mortality was 0.658 (95% CI: 0.584, 0.732), while the AUC for ECI-vw in predicting the same outcome was 0.663 (95% CI: 0.584, 0.741). For predicting all-cause mortality within 7 days post-surgery, the AUC of ACCI was 0.680 (95% CI: 0.04, 0.56), and for ECI-vw, it was 0.532 (95% CI: 0.353, 0.712). Regarding the prediction of all-cause mortality within 28 days after surgery, the AUC for ACCI was 0.724 (95% CI: 0.622, 0.827), and for ECI-vw, it was 0.653 (95% CI: 0.538, 0.69). Patients were categorized into two groups based on the ACCI cutoff value of 3.5, including Group 1 (ACCI 3.5 points, 173 cases). The overall survival rate for these two patient groups was calculated using the Kaplan-Meier method, revealing that the 28-day postoperative survival rate for patients in Group 1 was significantly higher than that for patients in Group 2 (P

Abstract Objective To summarize the clinical features, imaging characteristics, and surgical diagnosis and treatment experience of mediastinal extramedullary hematopoiesis. Methods By summarizing and analyzing the case data and reviewing the literature, one case of posterior mediastinal extramedullary hematopoiesis on thoracoscopic biopsy in our department was summarized. Conclusion Posterior mediastinal extramedullary hematopoiesis is a response to failure of bone marrow erythropoiesis, which is relatively rare clinically, and diagnosis requires a combination of patient history and imaging, puncture biopsy or thoracoscopic excisional biopsy can provide a pathological diagnosis, and surgical complete resection is the main treatment modality.

Abstract Background Double aortic arch (DAA) is a type of vascular ring, causing stridor and dysphagia owing to compression of the trachea and esophagus. In contrast, double innominate veins, which is a relatively rare venous anomaly, usually does not cause symptoms or require intervention. Case presentation A 2 month-old boy presented with mild stridor and a hoarse voice while crying, and was diagnosed as having DAA, small atrial septal defects and double innominate vein. The double innominate veins, crossing over and underneath the ascending aorta, did not contribute to airway compression. To release the narrow vascular ring caused by the DAA, surgical resection of the atretic side of the arch was performed by lateral thoracostomy at 4 months of age, before the appearance of signs of bronchomalacia. The double innominate veins were left untouched, and open-heart surgery was avoided. Conclusions DAA should be suspected if airway symptoms are present in early infancy, particularly if a right aortic arch is noted. It is important not to hesitate to perform diagnostic imaging and release the DAA, as this might prevent or minimize airway complications. However, for double innominate veins, operative release is not necessary unless it interferes with surgical procedures or is causing symptoms.

Abstract The therapeutic approach to thymic cysts remains a subject of controversy. Predicted biomarkers for identifying thymic cysts and thymoma (THYM) are crucial. In this research, patients diagnosed with thymic cysts (MTC, n = 6) and thymoma (B1, n = 6; B3, n = 6) were enrolled. Proteins of superior quality were subjected to TMT labeling and UPLC-MS, and differentially expressed proteins (DEPs) were identified. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and protein-protein interactive network analyses were applied to the DEPs. Some key differentially expressed genes(DEGs) were corroborated through GEPIA 32. The pan-cancer expression levels of key DEGs remarkably linked with prognosis were determined utilizing The University of ALabama at Birmingham CANcer data analysis Portal (UALCAN). Eventually, 49 DEPs were identified in the B1 vs. MTC comparison (17 upregulated and 32 downregulated), 27 in the B3 vs. MTC comparison (8 upregulated and 19 downregulated), and 38 in the B3 vs. B1 comparison (9 upregulated and 29 downregulated). IL13RA1 (down), galectin-3 binding protein (LGALS3BP)(up), PRCSH (down), C3 (down), MXRA5 (down), TNN (down), CFHR1 (down), SUN3 (down) were jointly altered in both B1 vs. NZ and B3 vs. NZ. GEPIA validated that LGALS3BP was significantly upregulated in thymoma patients. In conclusion, LGALS3BP might be an essential biomarker to identify thymoma from the thymic cyst.

Abstract Introduction To mitigate gastroparesis as well as other post-operative complications, we undertook a prospective multicenter study to assess the feasibility, safety, and efficacy in the short-term outcomes of laparoscopic and thoracoscopic whole stomach esophagectomy with preoperative pyloric balloon dilatation. Methods A prospective descriptive study on 37 patients with laparoscopic and thoracoscopic whole stomach esophagectomy with preoperative pyloric balloon dilatation from January 2019 to March 2023. The perioperative indications, clinical data, intra-operative index, pathological postoperative specimens, postoperative complications, and follow-up results were retrospectively evaluated. Results In our study, all patients were male, with dysphagia as the predominant symptom (45.9%). Esophageal cancer incidence was similar between middle and lower thirds. Nodules were the primary finding on esophagoscopy (48.6%). Preoperative pyloric dilation averaged 31.2 min without complications. Surgical duration ranged from 225 to 400 min (mean 305). Gastric tube fluid volume averaged 148.9 ± 110.66 ml per day. Among 34 post-operative cases underwent gastric transit scans, most had non-dilated stomachs with efficient pyloric drug circulation. Three cases required prolonged ventilation, precluding pyloric circulation scans. Four patients developed chylous fistula, one requiring chest tube embolization. Recurrent laryngeal nerve damage occurred in 10.8% of cases. Conclusion After evaluating esophageal cancer patients undergoing laparoscopic whole-stomach esophagectomy with preoperative pyloric balloon dilatation, it was found that this procedure is safe, effective, and significantly reduces postoperative gastroparesis and related complications.

Abstract Background Due to its deep position and complex surrounding anatomy, the scapular glenoid fracture was relatively difficult to deal with especially in cases of severe fracture displacement. Improper treatment may lead to failure of internal fixation and poor fracture reduction, severely affecting the function of the shoulder joint. Inferior scapular glenoid fracture was Ideberg type II fracture, and posterior approach was commonly used to deal with inferior scapular glenoid fracture. However, there are shortcomings of above surgical approach for inferior scapular glenoid fracture, such as insufficient exposure of the operative field, significant trauma, and limited screw fixation direction. This study adopts the axillary approach for surgery, which has certain advantages. Methods The clinical data of 13 patients with Ideberg type II scapular glenoid fractures treated from December 2018 to January 2024 were retrospectively analyzed. There were 8 males and 5 females, with an age range of 19 to 58 years and an average age of 38 years. The causes of injury were falls from heights in 7 cases and car accidents in 6 cases. There were 5 cases on the left side and 8 cases on the right side. The time from injury to surgery was 2 to 11 days, with an average of 5.5 days. All cases underwent open reduction and internal fixation through the axillary approach. Postoperative X-ray and CT three-dimensional reconstruction were performed on the next day to evaluate the fracture reduction and the position of internal fixation. During the follow-up period, follow-up examinations were performed every two months in the first half of the year and every three months in the second half. CT scans were performed during the examinations to assess the glenohumeral joint congruence, fracture healing, and position of internal fixation. The shoulder joint function was evaluated at 6 months postoperatively according to the Constant-Murley value score. Results The patients all achieved primary wound healing after surgery, without any complications such as infection or nerve injury. Re-examination on the second day after operation, all fractures obtained excellent reduction, and the internal fixation was in excellent position, and no screw was found to enter the joint cavity. All patients in this group were followed up for 6 to 25 months, with an average follow-up time of 11.7 months. All fractures were bony unioned, and the healing time ranged from 4 to 6 months, with an average healing time of 4.8 months. At 6-month follow-up, according to the Constant-Murley score, 11 cases were excellent and 2 case was good. Conclusion Open reduction and internal fixation through the axillary approach is an feasible and safe surgical method for the treatment in scapular Ideberg type II glenoid fractures with less stripping of soft tissue, minimal surgical trauma, and the incision is concealed and beautiful. It can provide a strong internal fixation for fractures, so patients can perform functional exercise early after operation, and the clinical results is satisfactory.

Abstract Background The evolution of minimally invasive spine surgery, propelled by microscopy and endoscopy techniques, has reshaped the landscape of spinal interventions. The anterior approach to the cervical spine is widely recognized for its reproducibility and effectiveness in treating pathologies leading to radiculopathy or myelopathy. Apart from the traditional transdiscal approach, this study delves into the anterior transcorporeal approach, a minimally invasive technique, exploring its applicability in various cervical spinal pathologies. Purpose The objective is to comprehensively illustrate the anterior transcorporeal approach, exploring its historical development, biomechanical underpinnings, technical nuances, and clinical applications in managing cervical spine disorders. Methods We conducted a comprehensive review using PubMed, Embase, Cochrane Library, and Web of Science, adhering to PRISMA guidelines. The search was focused on the minimally invasive anterior transcorporeal approach for cervical pathologies, with an emphasis on evaluating the methodological evolution, technical execution, and clinical outcomes across diverse studies. Results The review identified a significant body of literature supporting the efficacy of the minimally invasive anterior transcorporeal approach. Over the past two decades, this approach has demonstrated encouraging clinical outcomes, suggesting its potential as an alternative strategy for specific cervical spine diseases. The evolution of this technique is tightly linked to the advancements in medical equipment and the innovative endeavors of surgical pioneers. Conclusions The anterior transcorporeal approach marks a milestone in minimally invasive cervical spine surgery. Its development reflects ongoing efforts to refine surgical techniques for better patient outcomes. While offering a promising alternative for treating certain cervical spine conditions, the approach demands precise case selection and is influenced by the rapid progression of medical technology. Future research and technological advancements are expected to further enhance the efficacy and safety of this approach, potentially expanding its indications in spinal surgery.

Abstract Background Advanced prostate cancer leads to many symptoms, notably bone pain and lower urinary tract symptoms (LUTs); however, the degree and duration of pain relief, changes in LUTs severity and underlying factors associated with the extent of symptom relief remain inadequately understood. Surgical castration has proven effective in relieving both bone pain and urinary symptoms for metastatic prostate cancer patients. Objective To determine the extent and pattern of symptom relief in advanced prostate cancer patients following surgical castration at Muhimbili National Hospital (MNH). Methods We conducted a prospective cohort study for a period of 6 months involving men with advanced Prostate cancer (PCa) undergoing surgical castration at MNH and followed them for 30 days. The international prostate symptoms score tool was used to assess changes in LUTs, and the pain rating scale was used for assessing changes in bone pain symptoms before and after surgery. Logistic regression model was used to determine factors associated with complete bone pain relief. Results A total of 210 participants with a mean age of 72.3 years were recruited. The LUTS score showed a decrease of 7.1 points after surgical castration (95% CI: 6.4 to 7.7, p

Abstract Objective This meta-analysis aims to compare the clinical efficacy of mesh non-fixation and fixation in laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair, systematically evaluating the application value of the mesh non-fixation technique in clinical settings. Methods A computerized search of PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov databases was conducted to identify randomized controlled trials (RCTs) comparing mesh non-fixation and fixation in TAPP inguinal hernia repair. Meta-analysis was performed using RevMan 5.3 software, and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) evidence grading system was employed for outcome quality assessment. Publication bias analysis was performed using Begg’s test. A trial sequential analysis (TSA) was performed using TSA 0.9.5.10 Beta software. Results A total of nine RCTs involving 1,879 inguinal hernia patients were included. Meta-analysis results demonstrated that, compared to the fixation group, the non-fixation group exhibited significantly lower seroma occurrence rate [RR = 0.43, 95% CI (0.20, 0.89), P = 0.02, heterogeneity P = 0.28, I²=22%], Visual Analog Scale (VAS) pain score at 6 months postoperatively [MD=-0.21, 95% CI (-0.29, -0.12), P

Abstract Objective To investigate the current situation and influencing factors of postoperative nausea and vomiting (PONV) in lung cancer patients undergoing thoracoscopic surgery under general anesthesia, providing a reference for developing targeted PONV prevention and management strategies. Methods Using a consecutive sampling method, 200 lung cancer patients who underwent their first thoracoscopic surgery under general anesthesia between November 18, 2021, and March 1, 2022, at a tertiary class A cancer hospital in Liaoning Province, China, were selected. The occurrence of PONV within 24 h post-operation was assessed using WHO Postoperative Nausea and Vomiting Rating Criteria. Patient general information, surgical and medication data were systematically collected to analyze the independent influencing factors of PONV. Results Among the 200 patients undergoing thoracoscopic lung cancer surgery under general anesthesia, 75 (37.5%) experienced PONV. Logistic regression analysis indicated that being female, having a history of motion sickness, and a history of PONV were independent risk factors for the occurrence of PONV in these patients. Long-acting antiemetics such as penehyclidine hydrochloride and methylprednisolone were protective factors against PONV. Conclusion The incidence of PONV in patients undergoing thoracoscopic lung cancer surgery under general anesthesia is relatively high. Nursing staff should focus on female patients and those with a history of motion sickness and PONV. Comprehensive preoperative assessments should be conducted, exploring multimodal analgesia and applying integrated prevention measures to reduce the occurrence of PONV and promote the rapid recovery of patients.

Abstract Background Postoperative pancreatic fistula (POPF) continues to be the most common complication after distal pancreatectomy (DP). Recent advancements in surgical techniques have established minimally invasive distal pancreatectomy (MIDP) as the standard treatment for various conditions, including pancreatic cancer. However, MIDP has not demonstrated a clear advantage over open DP in terms of POPF rates, indicating the need for additional strategies to prevent POPF in MIDP. This trial (WRAP study) aims to evaluate the efficacy of wrapping the pancreatic stump with polyglycolic acid (PGA) mesh and fibrin glue in preventing clinically relevant (CR-) POPF following MIDP. Methods This multicenter, randomized controlled trial will include patients scheduled for laparoscopic or robotic DP for tumors in the pancreatic body and/or tail. Eligible participants will be centrally randomized into either the control group (Group A) or the intervention group (Group B), where the pancreatic stump will be reinforced by PGA mesh and fibrin glue. In both groups, pancreatic transection will be performed using a bioabsorbable reinforcement-attached stapler. A total of 172 patients will be enrolled across 14 high-volume centers in Japan. The primary endpoint is the incidence of CR-POPF (International Study Group of Pancreatic Surgery grade B/C). Discussion The WRAP study will determine whether the reinforcement of the pancreatic stump with PGA mesh and fibrin glue, a technique whose utility has been previously debated, could become the best practice in the era of MIDP, thereby enhancing its safety. Trial registration This trial was registered with the Japan Registry of Clinical Trials on June 15, 2024 (jRCTs032240120).

Abstract Introduction Obstructive upper GI cancer commonly uses feeding jejunostomy as a standard procedure. Surgeons implemented laparoscopic feeding jejunostomy via minimally invasive surgery, employing a variety of techniques. This study assessed the perioperative results, safety, and costs associated with laparoscopic versus open jejunostomy surgeries. We used only Witzel’s tunnel and standard laparoscopic instruments. Patients and methods We collected data from all patients who underwent feeding jejunostomy between January 2016 and June 2018. We recorded pertinent data on baseline, surgical outcomes, postoperative results, complications, and costs. The study excluded patients with jejunostomy as a conversion or an addition. Result We divided the 74 patients into 2 groups: 30 underwent laparoscopy and 44 underwent open surgery. The mean operational times were 89.67 and 91.64 min and showed no statistically significant difference (p = 0.678). The mean morphine dosage was significantly lower in the laparoscopic group (3.3 vs. 7.19, p =

Abstract Background Fracture of the femur is one of the most common fractures that, if not stabilized and treated properly, may lead to severe disability, impairment of the individual’s efficiency, and numerous complications. This study aimed to evaluate the treatment results of femoral shaft fracture with two methods intramedullary nail (IMN) and Plate. Materials and methods In this cross-sectional study, 60 patients with femoral bone fractures were admitted to Imam Khomeini Hospital in Jiroft in 2020 and were treated for at least one year after discharge. They were divided into two treatment groups - Plate fracture fixation (n = 30) and IMN fracture fixation (n = 30). Data were collected using a researcher-made checklist including patient demographics and treatment outcomes. The collected data were analyzed using SPSS-v 26 statistical software and descriptive and inferential statistical tests at a significance level of p

Abstract Background To introduce a new flange technique (called the Z.S. fixation technique) for 8 − 0 polypropylene suture in scleral fixation of a one-piece intraocular lens (IOL) and evaluate its effectiveness and safety. Methods All surgeries were performed using two strategies. First, the Z.S. fixation technique was used to fix 8 − 0 polypropylene sutures to the sclera and the two haptics of a one-piece IOL, respectively. The one-piece IOL previously implanted in the anterior chamber was then relocated to the posterior chamber. Finally, the suture ends outside the sclera were cauterized into flanges and buried in the sclera. All effectiveness and safety data related to the Z.S. technique were recorded and compared. Results The Z.S. fixation technique was employed in 16 eyes of 13 patients, with a follow-up duration of at least 6 months. Postoperative uncorrected distance visual acuity (UDVA) was greatly improved in most of the operated eyes (11/16). The mean log MAR UDVA after surgery was significantly improved compared with that before surgery (0.93 ± 0.72 vs. 1.53 ± 0.73, P = 0.002). IOLs in the vast majority of operated eyes (15/16) remained stable during half-year follow-up. No severe intra-/post-operative complications were observed in any of the operated eyes. Conclusion The Z.S. fixation technique for 8 − 0 polypropylene suture in scleral fixation of one-piece IOL reduced surgical injuries and had ideal surgical effectiveness and safety.

Abstract Background Burn wounds require optimal medical management due to associated psycho-emotional and socioeconomic impacts and severe pain. The use of synthetic and biological dressings improves healing and reduces burn wound complications. The present study aimed to compare the outcomes of using human amniotic membrane (hAM) dressings and conventional silver sulfadiazine (SSDZ) ointment dressings in the management of second-degree burn wounds. Methods Fifty patients who participated in this clinical trial were divided into two groups via simple randomization. All the enrolled patients, who had burnt in the last 24 h, had thermal damage mechanisms and were suffering from less than 20% second-degree heat-burn wounds on the skin surface. The target group (n = 25) was treated with hAM, and the control group (n = 25) was treated with SSDZ ointment. The researcher-designed checklist was used to determine the clinical performance in the follow-up assessments on days 7, 14, and 30. Results No significant differences were detected in terms of sex, age, or percentage of burn wounds (p > 0.05). Wound epithelialization at days 7, 14, and 30, scar formation, wound pigmentation, pain severity, analgesia requirements, and hospital stay length (on day 30) were significantly lower in the target group (treated with hAM) than in the control group (treated with SSDZ ointment) (p

Abstract Background To prevent local recurrence caused by exfoliated cancer cells caught in the suture line, intraoperative rectal washout during surgery can be performed to eliminate exfoliated cancer cells. However, the impact of neoadjuvant chemoradiotherapy on exfoliated cancer cells is not well known. This study aimed to identify positive rate of malignant cells in rectal washout fluids of neoadjuvant chemoradiotherapy patients and to determine if neoadjuvant chemoradiotherapy could affect exfoliated cancer cells. Methods A total of 105 patients who underwent rectal washout intraoperatively for distal sigmoid colon and rectal cancer from April 2020 to September 2021 were analyzed. The primary outcome was positive rate of malignant cells in rectal washout fluids of patients who had received neoadjuvant chemoradiotherapy. Results The positive rate of malignant cells in washout fluids of patients who had received neoadjuvant chemoradiotherapy was 0.0% and those who had not was 32.1%. The overall positive rate was 23.8%. In the positive group, tumor sizes were bigger (4.64 ± 1.68 cm vs. 3.64 ± 2.00 cm, p = 0.026) and more patients had a fungating tumor shown in preoperative colonoscopy (96.0% vs. 71.3%, p = 0.012). Although these factors did not show statistical significance in multivariable logistic regression analysis, fungating tumor showed a trend towards significance (OR: 7.28, 95% CI: 0.90-58.77, p = 0.063). Conclusions Our study suggests that neoadjuvant chemoradiotherapy could reduce exfoliated cancer cells, and rectal washout for the purpose of eliminating exfoliated cancer cells might be unnecessary in patients who have received neoadjuvant chemoradiotherapy.

Abstract Background Traditional reconstructive options of fingertip injuries are technically difficult, usually need donor site skin grafting, leave visible scars, and need a protracted period of finger immobilization resulting in joint stiffness. Electro-photobiomodulation (EPBM), is the process of combining intense pulsed light and radiofrequency to modify tissues to help the body heal itself, lower inflammation, and promote wound healing. Patients and methods This study included 60 patients presented with fingertip injuries. Patients were randomly divided into two groups. Group 1 includes patients who were treated by EPBM. Group 2 includes patients who were treated by cross finger flap (CFF). Six months after complete healing, evaluation was performed for aesthetic and functional outcome and patient satisfaction. Results Compared to group 2 patients, group 1 patients had statistically significant better sensory outcome, better total active motion of affected digits, grip strength, patient satisfaction, healing time, and plastic surgeon general aesthetic evaluation and also, they had statistically significant less adverse events and cold intolerance with absent donor site pain and deformity. Conclusion EPBM is safe and effective treatment of fingertip injuries which shortens the healing time, produces the best aesthetic and functional result while avoiding donor site morbidity of the traditional reconstructive options.

Abstract Background Rib fractures are one of the most common traumatic injuries and may result in significant morbidity and mortality. Despite growing evidence, technological advances and increasing acceptance, surgical stabilization of rib fractures (SSRF) remains not uniformly considered in trauma centers. Indications, contraindications, appropriate timing, surgical approaches and utilized implants are part of an ongoing debate. The present position paper, which is endorsed by the World Society of Emergency Surgery (WSES), and supported by the Chest Wall Injury Society, aims to provide a review of the literature investigating the use of SSRF in rib fracture management to develop graded position statements, providing an updated guide and reference for SSRF. Methods This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of experts then critically revised the manuscript and discussed it in detail, to develop a consensus on the position statements. Results A total of 287 studies (systematic reviews, randomized clinical trial, prospective and retrospective comparative studies, case series, original articles) have been selected from an initial pool of 9928 studies. Thirty-nine graded position statements were put forward to address eight crucial aspects of SSRF: surgical indications, contraindications, optimal timing of surgery, preoperative imaging evaluation, rib fracture sites for surgical fixation, management of concurrent thoracic injuries, surgical approach, stabilization methods and material selection. Conclusion This consensus document addresses the key focus questions on surgical treatment of rib fractures. The expert recommendations clarify current evidences on SSRF indications, timing, operative planning, approaches and techniques, with the aim to guide clinicians in optimizing the management of rib fractures, to improve patient outcomes and direct future research.

Abstract Background Gastric cancer is one of the most common malignant tumors worldwide, with high incidence and mortality rates, and it has a complex etiology and complex pathological features. Depending on the tumor type, gastric cancer can be classified as intestinal-type and diffuse-type gastric cancer, each with distinct pathogenic mechanisms and clinical presentations. In recent years, machine learning techniques have been widely applied in the medical field, offering new perspectives for the diagnosis, treatment, and prognosis of gastric cancer patients. Methods This study recruited 2158 gastric cancer patients and constructed prognostic prediction models for both intestinal-type and diffuse-type gastric cancer. Clinical pathological data were collected from patients, and machine learning algorithms were used for feature selection and model construction. The performance of the models was validated with training and testing datasets. The Shapley additive explanations (SHAP) values were used to interpret the model predictions and identify the main factors that influence patient survival. Results In the prognostic model for intestinal-type gastric cancer, the gradient boosting decision tree (GBDT) model demonstrated the best performance, with key features including pTNM, CA125, tumor size, CA199, and PALB. Similarly, in the prognostic model for diffuse-type gastric cancer, the GBDT model was utilized, with key features comprising pTNM, Borrmann type IV disease, lymphocyte (LYM), lactate dehydrogenase (LDH), potassium (K), perineural invasion (PNI), tumor size, and whole stomach location. Risk stratification analysis revealed that the prognosis of high-risk patients was significantly worse than that of low-risk patients. Conclusion Machine learning shows great potential in predicting survival outcomes of gastric cancer patients, providing strong support for the development of personalized treatment plans.

Abstract Background Some colorectal cancers (CRCs) are clinically diagnosed as cT4a with serosal invasion (SI). However, the cT4a is most often underdiagnosed pathologically as pT3 without SI by hematoxylin–eosin (H&E) staining alone. Using Elastica van Gieson (EVG) staining, some pT3 tumors invade the elastic lamina (EL), which extends just below the serosal layer. Recently, EL invasion (ELI) has been described as a poor prognostic factor for disease-free survival (DFS) and overall survival (OS) in patients with pStage II CRC. However, its clinicopathological significance remains unclear due to the limited number of studies and poor understanding of ELI. Objective This study investigated the association between the ELI and patient prognosis. Methods After 1982, pathological diagnosis was routinely performed using H&E and EVG staining methods, and long-term follow up was performed until 2016. All clinicopathological features including ELI were prospectively registered into our computer and 569 patients with pStage II CRC were collected from the database. Based on the ELI status, pT3 was divided into three pathological categories: pT3ELI − was defined as pT3a, pT3ELI + as pT3b and unidentified EL (pT3EL −) as pT3u. Results Using H&E staining alone, gross cT4a was most often pathologically underdiagnosed as pT3 (93.8%) and very rarely as pT4a, resulting in a large diagnostic discrepancy. Using EVG staining, 60.7% of the cT4a tumors were diagnosed as pT3b. The 10-year DFS and OS rates were similar for pT3a and pT3u patients. However, the 10-year DFS and OS rates of pT3b patients were significantly lower than those of pT3a patients (75.6% vs. 95.6%, p

Abstract Simplified rapid hydration has been proven to be non-inferior to standard hydration in preventing contrast-associated acute kidney injury among chronic kidney disease patients undergoing coronary angiography. The current investigation aimed to further confirm the feasibility and safety of the newly proposed hydration method-simplified rapid hydration (SH) in each risk stratification by Mehran risk score (MRS). Eligible patients (n = 954) randomized to the SH group and standard hydration group were allocated into 2 groups based on MRS: low to moderate-risk and high to very high-risk groups. Primary endpoints were the incidence of contrast-associated acute kidney injury (CA-AKI) and acute heart failure (AHF) (SH vs standard hydration). Secondary endpoints included serum creatinine (Scr), blood urea nitrogen (BUN), cystatin-C (Cys-C), and C-reactive protein (CRP) at 24 h, 48 h, and 72 h after PCI procedure, and the incidence of major adverse cardiac events (MACE). MRS was associated with a higher incidence of CA-AKI (OR = 1.101, 95%CI 1.049–1.156, P

Abstract Background Preoperative oral carbohydrate intake can improve the postoperative recovery of fasting patients in many kinds of surgeries; however, the effect of carbohydrates on patients undergoing daytime oral surgery is still unclear. This study was designed to evaluate the effect of preoperative oral carbohydrate intake on the quality of recovery of patients undergoing daytime oral surgery using the quality of recovery-15 (QoR-15) questionnaire. Methods Ninety-two patients scheduled for daytime oral surgery were randomly allocated to the midnight fasting group (F group, n = 45) or the carbohydrate-Outfast loading group (O group, n = 47). Participants in the F group fasted from midnight the day before surgery. Patients in the O group also fasted but received the Outfast drink (4 ml/kg) 2–3 h before the induction of anesthesia. QoR-15 questionnaire, patient well-being, and satisfaction were assessed before anesthesia induction and 24 h after surgery. Perioperative blood glucose, postoperative exhaust time, and adverse events were also recorded. Results The QoR-15 scores were significantly higher in the O group than in the F group preoperatively and postoperatively. Seven parameters representing patient well-being evaluated on a numeric rating scale (NRS, 0–10) were lower in the O group than in the F group postoperatively, except for the hunger and sleep quality scores. Patient satisfaction scores on a 5-point scale were higher in the O group than in the F group preoperatively and postoperatively. Meanwhile, the postoperative exhaust time was significantly shorter in the O group compared to the F group, while there were no significant differences in blood glucose concentrations between two groups. Conclusions Preoperative oral carbohydrate intake could improve postoperative recovery quality, well-being, and satisfaction of patients undergoing daytime oral surgery 24 h after surgery, and may serve as a treatment option for patients undergoing daytime oral surgery.

Abstract Background Preoperative health optimisation for elective surgery entails supporting patients to improve their health in preparation for their treatment and recovery. While there is consensus that this process should address obesity, approaches vary across England. Despite guidance from the National Institute for Health and Care Excellence to the contrary, restrictive approaches with body mass index thresholds for referral to arthroplasty are in use. This qualitative study aimed to investigate the views of professionals on the current use and future implications of these policies. Methods Semi-structured interviews were conducted with 20 professionals including clinicians, commissioners, policymakers, and health service managers, with experience of developing and/or implementing health optimisation policies for elective arthroplasty. Participants were sampled from areas in England with and without restrictive policies. We undertook thematic analysis of the interview data. Results Participants described pre-surgical health optimisation as an important trigger for health improvement but identified current resourcing and inadequacies in provision of weight management support as significant barriers to success. Participants expressed concerns about the appropriateness and fairness of including obesity as a determinant to restrict access to surgery. They described short-term financial pressures underlying the use of restrictive body mass index thresholds and a lack of an evidence base, such that policies amounted to rationing and risked exacerbations of health inequalities. The study identified four priorities for improvements to future health optimisation practices: developing and implementing national guidance with flexibility for local variation, initiating patient engagement in primary care with onward integration across all services, improving resourcing to support effective equitable impact, and addressing wider determinants of obesity through societal change. Conclusions Overall, participants had limited expectations of the impact of health optimisation policies on obesity without additional support, investment, and national guideline implementation. They raised strong concerns over current restrictive approaches. We conclude that addressing concerns around weight management support service availability and impacts on health inequalities is essential for shaping effective health optimisation policies. Future policy direction should support health optimisation to be offered early (ideally in primary care). Health optimisation interventions should be non-restrictive, inclusive, and well-monitored, particularly around equality impact.

Abstract Background The airway should be thoroughly and accurately evaluated before anesthesia induction and endotracheal intubation. Awake direct laryngoscopy (ADL) can provide rapid, accurate, and intuitive airway assessment, especially for suspected difficult airways, and sometimes eliminates the need for fiberoptic intubation in some suspicious difficult airway cases. However, an optimal regimen has not been determined. Methods In this double-blind, controlled study, prior to ADL, 60 patients scheduled for general anesthesia were randomly allocated to receive 0.75 μg/kg of dexmedetomidine (Dex group, n = 20), 0.15 mg/kg of nalbuphine (Nal group, n = 20), or a placebo (control group, n = 20) intravenously over 10 min. At the same time, all study subjects received nebulized lidocaine for 15 min. The primary outcome was patient tolerance as assessed by a 5-point ADL comfort score, while secondary outcomes included satisfaction, coughing, pain, nausea and vital signs. Results Patients undergoing ADL in the Nal group had higher tolerance scores than those in the control and Dex groups [4 (3,4) vs. 3 (2,2.75), P

Abstract Background Surgical safety remains a critical global health concern, with complications from surgical procedures resulting in significant morbidity and mortality, particularly in low- and middle-income countries. The World Health Organization (WHO) Surgical Safety Checklist (SSC) has been shown to reduce surgical complications and mortality rates. However, its implementation and impact in resource-limited settings like Somalia remain understudied. This study aimed to evaluate the implementation of the WHO SSC in selected hospitals in Mogadishu, Somalia, and assess its impact on surgical safety practices. Methods A pre- and post-intervention study was conducted in 15 randomly selected hospitals in Mogadishu, Somalia. The intervention involved a comprehensive training program on the WHO SSC for surgical teams. Data on hospital characteristics, surgical details, and adherence to the SSC were collected over two periods: pre-intervention (April 12th to May 4th, 2024) and post-intervention (May 12th to June 3rd, 2024). The primary outcome was the adherence to the SSC, categorized as good (> 60%) or poor (≤ 60%). Descriptive statistics, McNemar’s test, and binary logistic regression were used for data analysis. Results Adherence to the WHO SSC significantly improved post-intervention, with 98.8% of surgical cases demonstrating good adherence compared to 37% pre-intervention (p

Abstract Background This study explores the factors contributing to the occurrence of delirium following cardiac surgery and devises nursing strategies rooted in behavior change theory. Methods A cohort of 320 cardiac surgery patients was selected, categorized into two groups: 93 cases where postoperative delirium (POD) was anticipated, and 227 cases where it was not. Preoperative, intraoperative, and postoperative factors of POD were scrutinized using single-factor analysis, while binary logistic regression analysis was employed to pinpoint risk factors. Results Among the 320 patients, 93 displayed POD symptoms post-surgery, yielding an incidence of 29.06%. Preoperative univariate analysis disclosed significant differences in gender, age, smoking, hypertension, and diabetes (P

Abstract Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by epistaxis, gastrointestinal bleeding, iron deficiency anemia, and arteriovenous malformations (AVMs) affecting the lungs, liver, and brain. Owing to its rarity and diagnostic challenges, early identification is often elusive. Underdiagnosis and prolonged diagnostic delays are prevalent. Here, we present the case of a 63-year-old male who presented with chest pain and was diagnosed with an ST-elevation myocardial infarction (STEMI). Subsequently, he underwent placement of a drug-eluting stent in the right coronary artery (RCA). However, recurrent postoperative epistaxis resulted in severe anemia, prompting further investigation leading to the diagnosis of hereditary hemorrhagic telangiectasia through comprehensive medical history and genetic testing. Future studies are warranted to evaluate reperfusion strategies in HHT patients presenting with myocardial infarction.
