Infection of prosthetic vascular grafts can manifest as pain, pseudoaneurysms, or arterial insufficiency in the leg. We present the case of a female patient with a medical history of a right external iliac artery endofibrosis, with a persistently infected synthetic iliofemoral bypass graft, which we replaced with a bioengineered human acellular vessel. At the 12-month follow-up visit, the clinical and radiologic studies demonstrated adequate human acellular vessel patency, with no signs of infection, stenosis, or pseudoaneurysm. Subsequent to the initiation of hormone therapy and cessation of antiplatelet therapy, the patient developed graft thrombosis. She continued to do well after restoration of patency with lytic therapy. At 22 months, secondary patency has been maintained with continued anticoagulation therapy, and the patient has remained asymptomatic.

Subclavian artery aneurysms are rare peripheral artery aneurysms, and open surgical repair is the reference standard treatment. We have reported the case a patient with a right subclavian artery aneurysm who was not indicated for open surgical repair because of comorbidities. Thus, endovascular treatment using the Gore Excluder Iliac Branch Endoprosthesis (WL Gore and Associates, Flagstaff, Ariz) was performed, leading to complete aneurysmal exclusion without perioperative complications. Although anatomic limitations exist, this technique could be alternative treatment option for right subclavian artery aneurysms.

Introduction Intestinal blood flow evaluation during strangulated bowel obstruction is often based on the subjective assessment of the operator. Therefore, we aimed to comprehensively determine the presence or absence of intestinal blood flow based on normal light and indocyanine green (ICG) fluorescence imaging. Moreover, we ascertained whether the chosen surgical plan was appropriate, based on the patients' postoperative course and pathological findings. Methods All 14 patients diagnosed with strangulated bowel obstruction at our hospital who underwent laparoscopic surgery between July 2019 and January 2021 were enrolled. Surgical plans were chosen based on normal light imaging combined with near-infrared imaging after intravenous ICG injection. Intestinal resection was performed via a small laparotomy if resection was considered necessary. In the intestinal resection group, the presence of intestinal necrosis was examined based on the pathological findings of the resected specimens. In the intestinal preservation group, postoperative complications, such as delayed intestinal perforation and intestinal stricture, were examined. Results Intestinal resection was performed in 4 cases. The pathological findings of the resected specimens showed necrosis of the small intestine in all cases. No intra-abdominal complication occurred any of the cases, and the median postoperative hospital stay was 9.9 days. Conclusions The selection of a surgical plan in conjunction with ICG fluorescence findings was valid in all 14 cases. ICG fluorescence imaging is useful in laparoscopic surgery for strangulated bowel obstruction and may be a novel method for evaluating intestinal blood flow during surgery.

Background Biliary atresia (BA) is a rare disorder characterized by obstructive jaundice in infants, shortly after birth. Postoperatively, some patients exhibit portal hypertension and progressive liver fibrosis. Splenomegaly is a symptom of portal hypertension. We aimed to investigate splenomegaly as a marker for complications of portal hypertension and the relationship between splenomegaly and liver fibrosis in the long-term native liver (NL). Methods Between 1977 and 2018, 71 patients underwent hepaticojejunostomy. We included 54 patients (34 NL group, 20 liver transplant (LT) group) who fulfilled the eligibility criteria. Spleen volume (SV), total bile acids, hyaluronic acid, type IV collagen, and aspartate aminotransferase-to-platelet ratio index (APRi) were measured. Data were analyzed using Student's t-test, regression analysis, and receiver operating characteristic (ROC) curve analysis (P Results Total bile acids, hyaluronic acid, type IV collagen, and APRi increased in NL patients with a large SV at >25 years. SV and type IV collagen were correlated with NL for >25 years (r = 0.79 [P = 0.006], y = 1.1 - [0.03 × type IV collagen] [P = 0.008]). In the ROC curve analysis, the cutoff value for type IV collagen was 165 ng/mL (P = 0.07). Conclusions We suggest that SV as a prognostic index for End-Stage Liver Disease may be useful in biliary atresia. Long-term follow-up is necessary because the clinical course may be favorable in childhood but worsen during adulthood.

We report a Case of a mycotic abdominal aortic aneurysm caused by invasive group B streptococcus. Given the anatomical suitability with healthy segments of aortoiliac vessels, in-situ repair was performed. A cryopreserved femoral vein graft was chosen due to risks of graft reinfection and negated the need for bilateral femoral vein harvest. The patient remained clinically well and the graft patent with no concerns at 6 months follow-up. A review of literature on group B streptococcus aortitis was performed.

Chronic limb-threatening ischemia in the pediatric population is a rare phenomenon. When open repair is necessitated, an autogenous conduit is preferred. However, venous grafts are prone to their own long-term complications. We have presented the case of a 10-year-old boy with chronic limb-threatening ischemia due to popliteal artery thrombosis that was treated with an ipsilateral great saphenous vein bypass. Seven years after the initial procedure, the venous graft had developed aneurysmal degeneration with acute thrombosis, necessitating bypass revision. Through the present case, we have discussed the surgical approach and highlighted the importance of long-term postoperative surveillance after open repair in the pediatric population.

Despite the advantages of anterolateral thigh (ALT) flaps, many surgeons are hesitant to choose a thigh with ipsilateral femoral fracture and internal fixation as the flap donor site. To cover the right mid-upper leg wound, a free ALT flap was harvested from the left thigh of a 55-year-old man who initially underwent closed retrograde intramedullary fixation for a left distal third femoral shaft fracture. The flap was based on a musculocutaneous perforator located in the mid thigh, which was approximately 10 cm above the proximal fracture level. No adhesion or scar formation between the fascia and adipose tissue was noted when the flap was raised supra-fascially, and the adipose tissue surrounding the trunk of the descending branch of the lateral circumflex femoral artery was found to have mild oedema. The patient regained good aesthetic outcomes and a complete range of active motion in both lower extremities. Based on current evidence of the vascular anatomy of the ALT flap in the literature and our experience, an ipsilateral thigh with distal third femoral shaft fracture and closed retrograde intramedullary fixation should not be considered an absolute contraindication to ALT flap harvesting.

The duration that renal parenchyma will tolerate ischemia has continued to be debated. We have reported the cases of three patients who had undergone revascularization procedures with successful return of baseline renal function after prolonged renal artery occlusion of 14 days to 3 months. These cases highlight that aggressive revascularization can lead to successful renal salvage in selected patients. We examined the characteristics of these patients and those of others in the literature and reviewed the factors favoring recovery.

We present a rare case of reconstruction surgery of Ideberg type V intra-articular scapular fracture nonunion postoperatively. Sufficient osteotomy for the mobilization of displaced fragments and good visualization of the glenoid fossa by infraspinatus tenotomy, capsular incision, and partial detachment of the glenoid posterior labrum through the Judet approach contributed to a good anatomical reduction of the glenoid fossa and favorable clinical outcomes. We describe a detailed surgical technique, management and clinical outcomes after a 1-year follow-up, with a review of the literature.

Background Surgical management of massive irreparable rotator cuff tears remains controversial. Arthroscopic debridement (AD) has shown promising results especially in the population older than 65 years; however, there is no consensus on the benefits of various AD procedures. The aim of this systematic review was to evaluate the functional midterm to long-term outcomes in patients treated with AD in combination with subacromial decompression, biceps tenotomy, tuberoplasty, or bursectomy, without repair of the rotator cuff tear. Methods A comprehensive search was performed in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Cochrane databases for studies reporting clinical outcomes of AD of massive rotator cuff tears. Quality was determined using the Methodological Index for Nonrandomized Studies (MINORS) criteria by two independent reviewers. Pooled frequency-weighted means and standard deviations were calculated for patient-reported outcomes. Results Sixteen articles containing 643 patients and 662 shoulders met the eligibility criteria. The mean age at the time of surgery was 65.9 ± 4.4 years with a mean follow-up period of 46.5 ± 27.3 months. There was notable clinically significant improvement across all patient-reported outcome scores postoperatively: Constant 70.4 ± 8.9 (P value = .06), University of California, Los Angeles ultrasonography 26.7 ± 5.2 (P value = .001), American Shoulder and Elbow Surgeons score 71.7 ± 2.1 (P value = .12), Disabilities of the Arm, Shoulder, and Hand score 35.3, and visual analog score 1.7 ± 0.9. Forty-nine patients (7%) required reoperation, which most commonly was a reverse total shoulder arthroplasty for the development of rotator cuff arthropathy. Conclusion Arthroscopic debridement with a combination of subacromial decompression, tuberoplasty, subacromial bursectomy, and biceps tenotomy, for treatment of massive irreparable rotator cuff tears, produces good functional outcomes and improvement in pain at mid to long term follow up for the low-demand population greater than 65 years of age looking for pain relief over substantial increase in function.

Total shoulder arthroplasty (TSA) is a safe procedure, with vascular injury being a rare complication [2, 5-8]. We present the case of a patient who underwent a TSA and subsequently presented 9 years later with an arteriovenous fistula (AVF) of the ipsilateral shoulder region, diagnosed on work-up for bruit noted in the shoulder region.

Langerhans cell histiocytosis (LCH) is a proliferative disease of histiocytic cells that rarely affects adults. Different therapeutic options have been used in the treatment of this condition depending on the severity of the disease. However, the management of LCH is often controversial when a resection with clean margins is not achieved. We present a 37-year-old male who was diagnosed with LCH affecting the middle third of the clavicle. The patient was subjected to a wide resection of the lesion creating a large bone defect. The reconstruction was then performed using a 3-D printed porous pseudo-prosthesis (Ti6AL4V) which was fixed using an anatomical clavicular plate (Depuy-Synthes, Raynham, MA, USA) and locking screws. The implant trabeculae were filled with bioactive bone graft substitute (GlassBONETM, Noraker, France). After two years of follow-up the patient was pain free, had a full range of movement, and scored 100 on the Constant Scale and 2.5 points on the disabilities of the arm, shoulder and hand score (DASH). Moreover, in this case, the implantation of the 3-D printed pseudo-prosthesis avoided the use of adjuvant therapies such as radiotherapy. The use of a 3-D printed pseudo-prosthesis achieved an excellent clinical and functional outcome in the treatment of a large bone defect, following a resection of a LCH of the clavicle. 3-D printed pseudo-prostheses could be useful instruments for the treatment of bone defects following large bone resections in musculoskeletal tumors.

Background Tumoral calcinosis has been reported in the literature in relation to various anatomical locations, but no articles have focused exclusively on this entity developing following reverse total shoulder arthroplasty. A 64-year-old Hispanic female with diagnosed tumoral calcinosis in the axillary region is discussed, along with the multi-factorial etiology and management of her condition. Case Presentation We chronicle the case of a patient who presented following a proximal humerus fracture who subsequently underwent a complicated course of medical and surgical management. After initially presuming an infectious process of her prosthetic joint based upon patient presentation, further workup consisting of histological specimens showing dystrophic calcifications and multinucleated giant cell cysts along with computed tomography exhibiting heterotopic bone formation aided in the diagnosis of periprosthetic tumoral calcinosis. Medical management, to include dialysis and chelation therapy, in combination with palliative resection and hardware revision were completed for pain relief. Conclusions Tumoral calcinosis complicating a total joint replacement is rare.Orthopaedic surgeons must remain diligent and keep an open mind when it comes to working up periprosthetic soft-tissue masses, taking into account all medical, radiographic, and pathologic data. Even with an integrated approach, including advanced medical and surgical interventions, tumoral calcinosis can only be symptomatically managed and will be a chronic source of pain and disability.

Summary: To compare the clinical efficacy and safety of Thulium laser enucleation of prostate (ThuLEP) and Holmium laser enucleation of prostate (HoLEP). We systematically searched PubMed, Embase, and Cochrane Library databases within a period from the date of database establishment to October 2020. RevMan 5.4. was used for calculation and statistical analyses. 8 studies of 2125 patients were included. ThuLEP provided less hemoglobin decrease (MD: −0.37, 95%CI -0.61 to −0.14, P = 0.002) and shorter length of hospital stay (MD: −0.41, 95%CI -0.72 to −0.10, P = 0.01). During the postoperative follow-ups, statistically significant differences only were found in IPSS (MD: −0.96; 95%CI -1.27 to −0.65; P

Summary Introduction To analyze the clinicopathological characteristics, immunohistochemistry, genotyping and prognosis of patients in the multicenter GIST data in Inner Mongolia, China. Methods Retrospective analysis was performed on GIST data from January 2013 to January 2018 in Inner Mongolia. Descriptive statistics were used to analyze the clinical characteristics of GIST patients. The Chi-square test was performed on the modified NIH criteria by age distribution, and Kaplan-Merie method was used for survival analysis. Results A total of 804 patients were included in the GIST database in Inner Mongolia, with a male to female ratio of 1.1102:1. The most common location was the gastric (465). Mitotic count ≤5/50HPFs was found in 67.3 % patients. There were 276 patients with tumor diameter of 2–5 cm and 354 patients with tumor diameter of 5.1–10 cm.The modified NIH criteria was mainly of intermediate risk (210) and high risk (342). The recurrence and metastasis of patients were related to the tumor location, mitotic index, tumor size, and modified NIH criteria. All patients were followed up for 1–10 years, in which 63.1 % of them were followed up for at least three years. The 3-year survival rates of patients with modified NIH criteria of very low risk, low risk, intermediate risk, and high risk were 100 %, 100 %, 100 %, and 96.3 %, respectively. Conclusions The incidence of GIST in middle-aged and elder people in Inner Mongolia is high, and the long-term prognosis of patients after surgical treatment is good, which can objectively reflect the incidence, diagnosis and treatment of GIST in Inner Mongolia.

Introduction: Assessments of early postoperative bony union after posterior lumbar interbody fusion via computed tomography (CT) have revealed cases in which interbody fixation by bony union resulted in nonfusion due to bone absorption. The apparent bone union state reverted to a nonunion state several months later, exhibiting a so-called “fake union” phenomenon. Additionally, few reports have evaluated the effect of teriparatide on bony union. The present study aimed to evaluate the frequency of change in assessment from fusion to nonfusion in the postoperative follow-up of lumbar interbody fusion, compare the late postoperative bony union rates in groups with or without early postoperative fusion, and examine the effect of postoperative teriparatide in those groups. Methods: Sixty-nine subjects enrolled from multiple hospitals were prospectively evaluated following single-level lumbar interbody fusion. The patients were randomly allocated into treatment with or without weekly postoperative teriparatide. The subjects were then classified as having bony union or nonfusion at 2 months postoperatively, and fusion rates at 6 months were compared. For the evaluation of bony union, blinded radiological examinations were performed via CT. Additional comparisons were made according to teriparatide use. Results: The rate of nonunion at 6 months postoperatively in patients with fusion at 2 months postoperatively was 27.8%. Among subjects with bony union at 2 months postoperatively, the fusion rate at 6 months in those who received teriparatide was 93.3% (p=0.027) versus 57.1% in those who did not. Conclusions: The rate of nonunion at 6 months postoperatively in patients exhibiting union at 2 months after surgery was 27.8%. Postoperative weekly teriparatide treatment significantly reduced the rate of fake union.

Introduction: Kyphotic deformity is common after spinal tumor resection surgery. An adequate field of view is needed to resect the spinal cord tumor, and, in some cases, the facet joint must be removed during laminectomy, and fixation may be performed simultaneously. In this study, we investigated the incidence of postoperative deformity after spinal tumor resection and the factors associated with postoperative deformity. Methods: We retrospectively analyzed patients who underwent thoracic spinal cord tumor resection at a single institution between 2010 and 2017 and were followed up for at least 24 months after surgery. Fifty percent or more of the facet joint was removed during the laminectomy, and fixation was performed simultaneously. Patients were divided into two groups, with and without kyphotic deformity. Patient demographic characteristics (age at surgery and gender), whether they underwent primary surgery or reoperation, tumor level, pathological type, and surgical method were compared. Multiple linear regression analysis was performed to identify independent predictors of kyphotic deformity. Results: Thirty-one patients were found to be eligible. Thirteen patients had intramedullary spinal cord tumors. Laminectomy was performed in 52% (N=16), laminoplasty in 6% (N=2), and laminectomy and/or laminoplasty combined with fusion in 42% (N=13) of the patients. During a mean follow-up period of 66.8 months, 12 (39%) patients had postoperative kyphosis deformities, of which one patient (3%, a 12-year-old girl who underwent combined postoperative radiation therapy) underwent kyphosis correction surgery three years after surgery. The number of laminectomies was independently associated with kyphotic deformity. Conclusions: Although kyphotic deformity after spinal tumor surgery was observed in about 39% of the patients, corrective surgery was rarely required due to the progression of the deformity. The high number of laminectomies is a risk factor for postoperative kyphosis, and prophylactic fixation may be considered in cases of multiple laminectomies.

Introduction Fistula Laser Closure (FiLAC) is a method that was originally applied in the treatment of perianal fistulas. Because of promising results, diode lasers were later on used to treat pilonidal sinus disease in a method called sinus Laser Closure (SiLaC). The aim of this study is to compare between SiLaC and Limberg flap in management of pilonidal disease. Methods A prospective, nonrandomized comparative study. A short-term follow-up of 71 patients with pilonidal disease was analyzed (24 operated on using the SiLaC technique and 47 using the Limberg technique). With a primary outcome is healing rate and recurrence and a secondary outcome is other measures i.e. complications, hospital stay and postoperative pain. Results The median operative time in the SiLaC group was 26.45 ± 5.41 min (20–35 min) and in the Limberg group 58.63 ± 7.42 min (50–75 min). In the SiLaC group, the primary healing was achieved in 23 out of 24 patients (95.8%) with a total complication rate of 20.83%. There were two cases of recurrence after initial healing in each group. Conclusion Sinus laser Closure (SiLaC) is comparable to Limberg flap technique in the terms of healing rate and recurrence with better outcome regarding operative time, hospital stay and post-operative pain.

Summary: The prevalence of postoperative low anterior resection syndrome (LARS) in patients with colorectal cancer is high, which seriously affects the quality of life after operation. The purpose of this meta-analysis is to systematically evaluate the related factors of LARS in patients with colorectal cancer and provide reference for clinicians when making reasoned decisions. A systematic electronic search of PubMed, Embase, The Cochrane Library, WANFANG and CNKI was performed from 2012 to Dec 2020. We analyzed the risk factors of LARS by extracting baseline data and clinical results. The odds ratio (OR) was used to analyze binary variables. A total of 5102 patients were included in 21 literatures, of which the prevalence of LARS was 49.7% (2538/5102). Meta-analysis showed that there was no significant difference in the influence of age (P = 0.48) and sex (P = 0.68) on LARS, but low tumor height (P

Aim This study aims to investigate the association of patient age with defecation disorders and anal function after lower rectal cancer surgery. Methods We retrospectively reviewed the data of 141 consecutive patients with lower rectal cancer who underwent sphincter‐preserving operation. The patients were classified into five categories by age thresholds at 65, 70, 75, 80, and 85 years, for disaggregate analysis. Anal manometry was used for measuring the maximum resting pressure, high‐pressure zone, and maximum squeeze pressure. Anal manometry was performed preoperatively and at 3, 6, 9, and 12 months postoperatively. The Wexner and low anterior resection syndrome scores were assessed at 1, 3, 6, 9, and 12 months after rectal surgery or stoma closure for patients with ileostomy. Results The data of 117 patients were reviewed. No significant differences were found between the younger and elderly groups in any characteristics across the six age groups. The preoperative intra‐anal pressures of the elderly patients were slightly lower than those of the younger patients; however, there was no significant difference in the course of postoperative intra‐anal pressures. Defecation disorder, as measured by the Wexner and low anterior resection syndrome scores, improved significantly in elderly patients compared to younger patients. Conclusion There was no significant difference in the course of postoperative intra‐anal pressures between the elderly and younger patients. However, defecation disorders in elderly patients significantly improved compared with younger patients. Sphincter‐preserving operation can be a viable treatment option for active elderly patients., The intra‐anal pressures were the same between the younger and the elderly after rectal surgery; however, defecation disorders in elderly patients significantly improved compared with those in younger patients. These new findings may help determine the optimal surgical procedure for lower rectal cancer in elderly patients. Sphincter‐preserving operation can be a good treatment option for active elderly patients.

Background CTCs play a critical role in the diagnosis and prognosis of liver cancer. However, there are few studies on whether different types of CTCs can predict the prognosis in patients with HCC following LT. Methods Retrospective data including CTCs detected by the CanPatrolTM platform combined with RNA-ISH were collected and analyzed on 56 patients from December 2016 to December 2019 at the Third Affiliated Hospital of Sun Yat-sen University, Guangzhou, Guangdong Province, China. Results During the study period, fifty-six patients (51 males, 5 females) were included with an mean age of 52 ± 9 years. The 1-, 2- and 3-year recurrence rates of postoperative interstitial CTC-positive and CTC-negative groups were 21.7% vs 10.8%, 37.5% vs 10.8% and 55.5% vs 10.8%, confirming a statistically significant difference between the 2 groups (p = 0.044). The 1-, 2- and 3-year recurrence rates of the increasing interstitial CTCs group were 25.2%, 36.9% and 66.9%, while 12.6%, 24.4% and 24.4% in the decreasing and unchanged group, indicating a significant difference (p = 0.038). Conclusion CanPatrolTM platform presents a superior analytical sensitivity, and may be used as a dynamic monitoring tool for CTCs. And interstitial CTCs which are more aggressive and metastatic caused by EMT can be regarded as a predictor of post-transplant tumor recurrence after LT for HCC.

Background: Pancreatic trauma results in significant morbidity and mortality. However, few studies have investigated the postoperative prognostic factors in patients with pancreatic trauma. Material and methods: A retrospective study was conducted on consecutive patients with pancreatic trauma who underwent surgery in a national referral trauma center. Clinical data were retrieved from the electronic medical system. Univariate and binary logistic regression analyses were performed to identify the perioperative clinical parameters that may predict the factors of mortality of the patients. Results: A total of 150 patients underwent laparotomy due to pancreatic trauma during the study period. 128(85.4%) patients survived and 22 (14.6%) patients died due to pancreatic injury (10 patients died of recurrent intra-abdominal active hemorrhage and 12 died of multiple organ failure). Univariate analysis showed that age, hemodynamic status, and injury severe score (ISS) as well as postoperative serum levels of C-reactive protein (CRP), procalcitonin, albumin, creatinine and the volume of intraoperative blood transfusion remained strongly predictive of mortality (P

Aim The clinical impact of abdominal aortic calcification (AAC) in patients who undergo hepatectomy for hepatocellular carcinoma (HCC) is unknown. Methods To evaluate the impact of AAC on clinical outcomes, we analyzed 203 patients who underwent hepatectomy for HCC between 2010 and 2013. Results Kaplan–Meier survival curve analysis showed significantly worse overall survival (OS) in the high AAC group than in the low AAC group. The recurrence‐free survival (RFS) was also significantly worse in the high AAC group. In the multivariate analysis, high AAC (hazard ratio [HR], 2.51; 95% confidence interval [CI], 1.24–5.09; P = .01) was an independent risk factor for poor OS after hepatectomy for HCC. High AAC was also an independent risk factor for poor RFS (HR, 1.69; 95% CI, 1.04–2.76; P = .04). Conclusions Abdominal aortic calcification had a strong relationship with poor OS and RFS after hepatectomy for HCC. We suggest that AAC had a relationship with smoking and diabetes; therefore, AAC could reflect a surrogate for older age, worse health status, and inflammatory score., Kaplan–Meier survival curve analysis showed significantly worse overall survival in the high abdominal aortic calcification (AAC) group than in the low AAC group.

Background: In recent years, breast reconstruction using autologous tissue after breast cancer surgery has become a common procedure. This study investigated the association between the occurrence of complications in breast reconstruction using deep inferior epigastric perforator (DIEP) flaps and patient risk factors among Asian women. Methods: This study included cases of breast reconstruction using DIEP flaps performed at our institution. We retrospectively investigated the relationship between preoperative and operative patient factors and postoperative complications by collecting data from medical records. Sarcopenia was also evaluated by calculating psoas muscle index from the area of the iliopsoas muscle at the level of the third lumbar vertebra using images from preoperative computed tomography. Postoperative complications were compared between a low-body mass index (BMI) group and a high-BMI group, defined using BMI values of

Major extremity haemorrhage is a surgical emergency and the physical examination is essential to help dictate appropriate clinical decision making. Hard signs that require immediate surgical intervention include ongoing bleeding, expanding hematoma, ischemic limb as well as partial/complete amputation. Packing, compression, balloon tamponade and tourniquets are very helpful to temporize major haemorrhage. Mangled extremities are very challenging to manage and require a multidisciplinary approach. Temporary vascular shunts are excellent tools for vascular/orthopaedic damage control and for temporary stabilization prior to transport for definitive care.

Summary Objective To explore the risk factors of cerebral neurological complications after surgery for Stanford type A aortic arch surgery. Methods One hundred sixteen patients who received Stanford type A aortic dissection from January 2012 to December 2019 were recruited. All patients received surgery under deep hypothermic circulatory arrest (DHCA) and general anesthesia. They were grouped by degree of postoperative cerebral neurological complication. The related factors of cerebral neurological complications were analyzed by single-factor analysis and multi-factor logistic regression. Results Postoperative neurological complications were observed in 31 cases (26.72 %). Two groups were identified: permanent neurological dysfunction (PND) was observed in seven cases, and temporary neurological dysfunction (TND) was observed in 24 cases. In-hospital mortality was 9.48 % (11/116), with six in the cerebral complication groups and five in the non-complication group. Single-factor analysis showed the associated factors were age, stroke history, carotid plaque or stenosis, emergency surgery, renal dysfunction, hypotension, aortic clamping time, deep hypothermic circulatory arrest time, postoperative hypoxemia, postoperative low cardiac output and plasma transfusion >800 ml, and erythrocyte suspension transfusion >6 U. Multi-factor logistic analysis showed the independent predictive factors were DHCA time >40 min, plasma transfusion >800 ml, erythrocyte suspension transfusion >6 U, history of stroke, and carotid plaque or stenosis. Conclusion The factors independently associated with neurological complications are DHCA time >40 min, plasma transfusion >800 ml, erythrocyte suspension transfusion >6 U, history of stroke, and carotid plaque or stenosis. Our findings suggest that patients with these risk factors should receive intervention during treatment to reduce cerebral neurological complications.

Background/objective: We investigated the efficacy of combined pigtail catheter crushing and AngioJet mechanical aspiration of thrombi in the treatment of acute iliofemoral deep venous thrombosis (DVT). Methods: Eighty-two patients with acute iliofemoral DVT were retrospectively divided into a pigtail catheter + AngioJet group (group A, 42 cases) and an AngioJet-only group (group B, 40 cases). The difference in the circumference of the healthy limbs before and after treatment, immediate thrombus clearance rate in the lower limbs, recannalization percentage of venous lumen, and duration of postoperative hematuria were compared to evaluate the safety and effectiveness of the combination method. Results: The technical success rate was 100%, no serious bleeding complications occurred, lower extremity symptoms were effectively alleviated, and post-treatment recannalization percentage of venous lumen were similarly high in both groups. Group A fared significantly better than group B in immediate thrombus clearance (P

Ulnar nerve entrapment at the wrist can cause debilitating sensory, motor, or sensory and motor deficits in the hand. The sources of compression have been well documented, with ganglions, lipomas, and trauma being common etiological factors. We treated a professional sculptor with intrinsic pain and weakness in her dominant hand because of compression caused by the subperiosteal course of her deep motor branch of the ulnar nerve. The nerve traversed on the radial side of the hook of the hamate and descended into the floor of the palm in the carpal tunnel through the transverse carpal ligament. We present this previously unreported anatomical anomaly and the subsequent operative treatment. Knowledge of this anatomical variation is paramount in avoiding injury to the ulnar nerve when operating the Guyon canal or carpal tunnel, among other hand and wrist surgeries.

Background/objective Sigmoid volvulus is the most common type of volvulus. Its epidemiological features, as well as its management, differ between developed and developing countries. This work aims to analyze the epidemiological features thus allowing to compare them to the rest of the “volvulus belt’’ and assess the surgical management of sigmoid volvulus in Tunisia. Method This is a retrospective review of 64 patients with sigmoid volvulus treated in the General Surgery department of Jendouba Hospital. January 2005–December 2019. Results 64 patients were treated for acute sigmoid volvulus. The sex ratio male to female ratio was 5.4/1 with male predominance. 5.4:1 (54 males to 10 females). The mean age was 62 years. The classic triad of intestinal occlusion was reported in 56 patients. The mean duration of symptoms was 4.2 days. An accurate preoperative diagnosis was made in 58 cases. Forty patients had a viable bowel obstruction, and all of them had a resection and primary anastomosis. Sixteen patients had a gangrenous bowel obstruction, of which 6 patients had resection-primary anastomosis, and 10 had Hartmann's procedure. Out of the total five deaths reported, there were only two among patients who had resection-primary anastomosis for gangrenous bowel obstruction. The most common postoperative complication was wound infections in 5 cases. The median length of hospital stay following surgery was 8 days. No recurrences of volvulus after a median follow-up of 11 months. Conclusions Although Tunisia belongs to the volvulus belt, the epidemiologic features of sigmoid volvulus tend rather be similar to those of developed countries. The use of primary surgery, if no endoscopy is performed, is a good alternative. For patients who have contraindications for endoscopic treatment, surgical treatment is the only option.

A 57-year-old man with diabetes mellitus presented with a 4-day history of left palm pain out of proportion, with swelling, erythema, and dense median and ulnar nerve distribution sensory changes. Magnetic resonance imaging with and without contrast revealed diffuse hand edema and myonecrosis. The patient was treated surgically because the examination was concerning for acute carpal tunnel syndrome and ulnar nerve compression. Spontaneous diabetic myonecrosis is a complication of diabetes mellitus that can be confused with several other conditions. It presents as acute-onset painful swelling in any muscle, and in the hand, may cause compressive neuropathies that necessitate surgical intervention.

Background A Chinese surgical robot, Micro Hand S, was introduced for clinical use as a novel robotic platform. This study aimed to comprehensively compare the early experience of the Micro Hand S robot-assisted total mesorectal excision (TME) with conventional approaches. Methods Between May 2017 and April 2018, 99 consecutive patients who underwent open, laparoscopic and Micro Hand S robot-assisted TME (O-/L-/RTME) for rectal cancer were included. Clinical and pathological outcomes were retrospectively analyzed. Surgical success as the primary endpoint was defined as the absence of (i) conversion, (ii) incomplete TME, (iii) involved circumferential and distal resection margins (CRM/DRM), (iv) severe complications. Results The rate of surgical success was similar (89.7 vs. 86.4 vs. 84.6%, p = 0.851) in the three groups and the respective incidences were as follows: conversion (not applicable, 4.5 vs. 2.3%, p = 1.000), incomplete TME (6.9 vs. 6.8 vs. 3.8%, p = 0.980), involved CRM/DRM (0 vs. 2.3 vs. 3.8%, p = 0.592), severe complications (3.4 vs. 4.5 vs. 7.7%, p = 0.844). Compared with open and laparoscopic surgery, the robotic surgery was associated with longer operative time, less blood loss, earlier first flatus time and liquid intake time, and shorter length of hospital stay (p Conclusions The Micro Hand S assisted TME is safe and feasible, showing comparable outcomes than conventional approaches, with superiority in blood loss, recovery of bowel function, length of hospital stay, but with increased operative time.

Summary Objective The prevalence of hemorrhoids has been reported to be 7–14%. However, there have been no large-scale studies. This study aims to investigate the incidence of hemorrhoids in Korea by analyzing big data and to find the associated risk factors. Methods This was a retrospective analysis using the Health Insurance Cohort database of the National Health Insurance Corporation of Korea in 2002–2015. The study was divided into two models: the diagnostic (DM) and surgical model (SM). Socio-demographic and lifestyle behavioral characteristics were analyzed as risk factors. Results Overall, 467,567 participants were included. The incidence density of hemorrhoids was 13.9 and 5.7 per 1000 person-years in the DM and SM, respectively. Hemorrhoids occurred more frequently in men and metropolitan areas in both models. The incidence was highest in the 40s. The incidence rates were highest in the high income, smoking, alcohol and the exercise group of 1–4 times a week in both models. The adjusted hazard ratio (HR) was higher in men and decreased with increasing age. It was higher in the metropolitan area. The high-income level and alcohol consumption were risk factors in the DM and SM, respectively. The HR of the exercise group was higher than that of the non-exercise group in both models. Conclusions The diagnostic and surgical incidence density was 13.9 and 5.7 per 1000 person-years, respectively. Hemorrhoids occurred most frequently in men in their 40s. The metropolitan area, high income level and alcohol consumption were associated with an increased frequency of hemorrhoids.

Objective We aimed to discuss the underlying oncological issues in staging of mediastinal lymph node metastasis in patients with left lung cancer who underwent extended radical lymphadenectomy (ERL). Methods This multi-institutional retrospective study analyzed 116 patients with left non-small-cell lung cancer who underwent bilateral paratracheal lymph node dissection (ERL) via median sternotomy. The clinicopathological records of patients with mediastinal lymph node metastasis were examined for prognostic factors, including age, sex, histology, tumor size, cN number, preoperative data, metastatic stations (number and distribution), pT, and adjuvant chemotherapy. Results Mediastinal lymph node metastases were found in 43 patients, and right paratracheal lymph node metastases (pN3) were found in 13 patients. The 5-year overall survival rate was 25.2% in patients with pN3 tumors (n = 13) and 23.1% in patients with pN2 tumors (n = 30). The prognosis did not differ between patients with pN3 and pN2. Univariate analyses showed that histology, cN, and adjuvant chemotherapy were significant prognostic factors in patients with mediastinal lymph node metastasis. In these 43 patients, cN and adjuvant chemotherapy were significant independent prognostic factors in multivariate analysis. Conclusions The prognostic factors for left lung cancer with mediastinal lymph node metastasis were cN status and adjuvant chemotherapy, and not pN status (pN2 or pN3). We hope that the study results, which suggest that there may be no difference in prognosis between pN2 and pN3, would broaden the discussion of oncological issues in the staging of mediastinal lymph node metastasis of left lung cancer.

Background Patients with gastric cancer are aging in Japan. It is not clear which patients and which surgical procedures have survival benefits after gastrectomy. A multivariate analysis was performed. Methods The medical records of 166 patients aged ≥ 80 years who underwent gastrectomy without macroscopic residual tumors were retrospectively reviewed. Univariate and multivariate analyses using Cox proportional hazard models were performed to detect prognostic factors for overall survival. Results In univariate analyses, age (≥ 90 vs. ≥ 80, Conclusions ASA-PS was a useful predictor for postoperative mortality. Gastrectomy including cardia is best avoided.

The prevalence of atrial fibrillation (AFib) in adult patients with atrial septal defect (ASD) who did not undergo ASD repair in the childhood is higher than that in general population. The primary aim of this study is to collect various related articles published in the literature and to compare the clinical outcomes with different treatment strategies by systemic reviews and meta-analyses. Of the 1299 initially screened articles, 13 studies with 213 patients were included in this study. All the patients were adults and the mean age at presentation was 55.7 years (range 34–79 years) and 47.8% of the patients were male. Regarding the types of the AFib, there were paroxysmal AFib in 62 patients, persistent AFib in 40 patients and long-standing persistent AFib in 111 patients. For adult patients with ASD and AFib, ASD closure is beneficial for most of the patients if significant left-to-right shunt exists but risk stratification cannot be overlooked because worsening of the functional class may be experienced by some patients post-operatively, especially for the patients with advanced age (>75 years). Reduction of prevalence of AFib could be observed after ASD closure alone which is mainly effective for paroxysmal AFib but not for persistent or long-standing persistent AFib. The successful ablation rate of paroxysmal AFib by catheter ablation is similar to that of all kinds of AFib by surgical ablation. Regarding AFib recurrence, bi-atrial surgical ablation is better than right-atrial ablation for the adult patients with ASD and AFib.

Background: The prognostic nutritional index (PNI) is used to assess immune and nutritional status, and is a prognostic factor for several malignant tumors. However, little evidence exists regarding the predictive impact of prognostic nutritional index (PNI) after local ablation therapy for hepatocellular carcinoma (HCC). The aim of this study was to evaluate the value of PNI to predict recurrence and survival after operative microwave ablation in patients with early-stage HCC. Methods: This retrospective study included 341 patients who underwent operative microwave ablation for HCC in Barcelona Clinic Liver Cancer (BCLC) stage 0-A at our institute between 2007 and 2015. We analyzed overall survival (OS) and recurrence-free survival (RFS), and evaluated factors related to prognosis in multivariate Cox regression analyses. Results: The OS rates at 1, 3, 5, and 10 years after microwave ablation were 100%, 92.7%, 85.1%, and 57.5% in patients with high-PNI levels, and 96.5%, 78.2%, 59.7%, and 20.7% in patients with low-PNI levels, respectively (P

Summary Background/objective Gastric outlet obstruction can have a large impact on quality of life for patients with upper gastrointestinal cancer or benign obstruction. Partial stomach-partitioning gastrojejunostomy has previously shown promising outcomes compared to conventional gastrojejunostomy in terms of reduced delayed gastric emptying. The objective of the current study was to present outcomes of partial stomach-partitioning gastrojejunostomy in a single high-volume center for upper gastrointestinal cancer. Methods A retrospective cohort study including all consecutive patients who underwent partial stomach-partitioning gastrojejunostomy from 2013 to 2020. The primary outcome was oral intake tolerance. A subgroup analysis was performed in all patients with manifest gastric outlet obstruction comparing partial stomach-partitioning gastrojejunostomy to conventional gastrojejunostomy. Results Partial stomach-partitioning gastrojejunostomy was performed in 32 patients and laparoscopic technique was used in 19 patients (59%). The procedure improved oral intake tolerance defined by gastric outlet obstruction scoring system by 0.63 points on average (P = 0.041). No postoperative complications related to the procedure were observed. Recurrence of gastric outlet obstruction developed in six patients (19%), four patients (13%) required endoscopic reintervention but no patient required surgical reintervention. A comparison between partial stomach-partitioning gastrojejunostomy and conventional gastrojejunostomy showed no statistically significant differences regarding postoperative nutritional status, length of hospital stay, recurrence or reintervention. Conclusion The results of the study show that partial stomach-partitioning gastrojejunostomy can be an effective surgical treatment for patients suffering from gastric outlet obstruction and that the procedure can be safely performed with laparoscopic technique.

Ozaki et al. first performed aortic valve replacement using autologous pericardium in 2007. Compared to mechanical and bioprosthetic valves which have apparent disadvantages, this technique has been an alternative with a promising safety and efficacy result. A comprehensive search was carried out in 4 databases (Pubmed, Cochrane Library, Proquest, Scopus) from February to March 2021 using search terms “autologous pericardium”, “aortic valve replacement”, and “aortic valve reconstruction”. Outcomes measured in this study were mortality, freedom of operation, thromboembolic and endocarditis event, and echocardiography finding. Risk bias of all studies was measured using MINORS criteria. A total of 12 studies involving 1427 subjects were included. The mean age was 64.95 years and 52.1% subjects were male. Mortality due to cardiac and noncardiac cause was 1.75%. Reoperation was needed in 1.12% subjects. Thromboembolic and endocarditis events occurred in 0.21% and 0.91% respectively. All studies reported lower average peak pressure gradient after surgery. Aortic valve replacement using autologous pericardium has a tolerable safety and efficacy. Resumen: Ozaki et al. realizaron por primera vez el reemplazo de la válvula aórtica utilizando pericardio autólogo en 2007. En comparación con las válvulas mecánicas y bioprotésicas, que tienen aparentes desventajas, esta técnica ha sido una alternativa con un resultado prometedor de seguridad y eficacia. Se realizó una búsqueda exhaustiva en 4 bases de datos (Pubmed, Cochrane Library, Proquest y Scopus) de febrero a marzo de 2021 utilizando los términos de búsqueda pericardio autólogo, reemplazo valvular aórtico y reconstrucción valvular aórtica. Los resultados medidos en este estudio fueron mortalidad, libertad de operación, evento tromboembólico y hallazgo ecocardiográfico. El sesgo de riesgo de todos los estudios se midió mediante los criterios MINORS. Se incluyeron un total de 12 estudios con 1.427 sujetos. La edad media fue de 64,95 años y el 52,1% de los sujetos eran varones. La mortalidad por causa cardíaca y no cardíaca fue del 1,75%. Se produjeron episodios tromboembólicos y endocarditis en un 0,21% y un 0,91%, respectivamente. Todos los estudios informaron de un gradiente de presión máxima promedio más bajo después de la cirugía. La sustitución valvular aórtica mediante pericardio autólogo tiene una seguridad y eficacia tolerables.

Background Analysis of long-term clinical outcomes of patients with familial adenomatous polyposis is critical in reducing or preventing the incidence of extracolonic malignancies after initial surgery. The aim of the present study was to clarify the long-term outcomes, and establish a surveillance strategy for surgically treated familial adenomatous polyposis patients. Methods Between January 1967 and March 2020, retrospective data were collected from 37 patients with familial adenomatous polyposis treated or monitored in our department. Occurrence of metachronous cancers, including rectal cancers and extracolonic malignancies, and other diseases was analyzed. Results The median follow-up duration after the first surgery was 13.8 years. Initially, 16 patients underwent total proctocolectomy with ileal pouch-anal anastomosis, 18 underwent total colectomy with ileorectal anastomosis, and three underwent other procedures. A secondary proctectomy was performed for 9 of the 18 patients who underwent ileorectal anastomosis. Rectal cancer was diagnosed in 6 patients who underwent ileorectal anastomosis. In addition, 5 gastric cancer, 2 duodenal cancer, 1 gallbladder cancer, and 1 thyroid cancer cases were diagnosed. The age at which the extracolonic malignancies were diagnosed was >50 years. 4 patients died due to metachronous rectal cancer, gastric cancer, or gallbladder cancer. Conclusion Careful consideration should be paid before choosing ileorectal anastomosis as the treatment procedure for familial adenomatous polyposis patients because completion proctectomy was eventually necessary for half of the patients. Long-term surveillance, with more frequent gastric surveillance for patients over 50 years, is important for the prevention and treatment of extracolonic malignancies in familial adenomatous polyposis patients.

Background Postoperative pancreatic fistula (POPF) is one of the major complications after pancreaticoduodenectomy. There have been many studies into the risk factors determining POPF. Some studies have reported a higher peri-operative fluid balance associated with POPF, however, the pertinent findings remain controversial. The aims of this study were to determine risk factors of clinically relevant-post operative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy and an association between peri-operative fluid balance and the incidence of CR-POPF. Materials and methods This is a retrospective cohort study included all adult patients who underwent an elective open pancreaticoduodenectomy in our center from 2005 to 2018. Patients who did not have POPF related data were excluded from study. We divided patients into CR-POPF and no CR-POPF group. Peri-operative data including amount and type of fluid were compared between two groups. Logistic regression analysis was used to identify the independent risk factors of CR-POPF. Results There were 223 pancreaticoduodenectomies done in our center during that period. The incidence of CR-POPF was 15.2 %. Patients in CR-POPF group had significant higher BMI, higher serum globulin level, smaller pancreatic duct diameter and higher cumulative fluid balance per body weight (FBPBW) at post-operative day 3. Multivariable analysis showed BMI >23 kg/m2, diagnosis other than pancreatic duct adenocarcinoma or chronic pancreatitis and higher cumulative FBPBW at post-operative day 3 were the independent risk factors for CR-POPF. Conclusions Post-operative fluid balance was the post-operative modifiable risk factor to reduce CR-POPF. Higher positive post-operative fluid balance should be avoided especially in higher CR-POPF risk patients.

Background: Stomach cancer is the fifth most common malignancy. In 2012, 952,000 cancers were diagnosed worldwide, which led to 723,000 deaths. Elderly men are the most frequently observed category of gastric cancer patients, mostly affecting the antrum. The objective of this study was to analyze the association of age with sex, tumor sites, types of surgical intervention, and diagnosed anatomical pathologies in cases of gastric cancer. Methods: This cross-sectional descriptive study analyzed the associations between age, sex, tumor sites, types of surgical intervention, and diagnosed anatomical pathologies among the total gastric cancer incidences during medical treatments from January 2016 to May 2019. The study samples were collected from the total gastric cancer respondents who met the inclusion criteria during medical treatments within the study period. Results: Gastric cancer was most frequently observed among females (56%) and those aged 50–70 years old (47%). Most respondents had advanced stages of gastric cancer at first enrollment at our institution. The most frequently found tumor site was the corpus (43%). The most frequently performed type of surgical intervention was jejunostomy feeding (26%), and the most frequently diagnosed anatomical pathology was adenocarcinoma with poorly differentiation (39%). Overall, age had statistically significant correlations with sex (p 50 years old), gastric cancer was more prevalent in women than men, and the gastric tumor tended to be more distal. Non-cardia gastric cancers were more prevalent than cardia gastric cancers.

BackgroundImmune checkpoint inhibitors were used for patients with advanced non-small cell lung cancer (NSCLC) more and more frequently and the effects were thrilling. Toripalimab as a new immune checkpoint inhibitor has been shown to be effective in patients with advanced NSCLC. However, data regarding the safety and feasibility of surgical resection after treatment with toripalimab for NSCLC remain scarce. Here, we present a case with locally advanced NSCLC that received video-assisted thoracic surgery (VATS) lobectomy after treatment with toripalimab in combination with chemotherapy.Case presentationA 62-year-old male patient with a history of coronary artery stenting operation for two times was found a 3.4 × 3.2 cm cavity mass in the upper lobe of the left lung and enlarged left hilar and mediastinal lymph nodes. Pathological results identified squamous cell carcinoma. The patient was diagnosed with a locally advanced NSCLC and received VATS left upper lobectomy and lymph node dissection after neoadjuvant chemotherapy plus toripalimab for 3 cycles. The postoperative pathological results showed complete tumor remission. Short-term follow-up results were excellent, and long-term results remain to be revealed.ConclusionsOur preliminary results showed that the use of neoadjuvant toripalimab and chemotherapy for the locally advanced NSCLC before surgical resection is safe and feasible.

Background The albumin‐bilirubin (ALBI) grade was developed to predict the prognosis of patients with hepatocellular carcinoma (HCC), which can stratify the prognosis even in HCC patients with Child‐Pugh A. We evaluated the prognostic efficacy of the ALBI grade and Child‐Pugh classification in HCC patients with Child‐Pugh A stratified by the presence or absence of advanced fibrosis or a preoperative biomarker for advanced fibrosis. Methods We retrospectively analyzed 490 consecutive HCC patients with Child‐Pugh A who underwent initial hepatectomies. The accuracy of prognostic prediction using both models was compared by the presence or absence of advanced fibrosis (F3‐4) and its predictor, the preoperative platelet count (PLT). Results The prognostic accuracy of the ALBI grade was better in patients without advanced fibrosis (F3‐4; likelihood ratio: 4.39, corrected Akaike information criterion [AICc]: 453.0, P = .074), but Child‐Pugh score was better in the advanced fibrosis group (likelihood ratio: 10.67, AICc: 915.2, P = .0014). In the high PLT group (≥140 × 103/μL), the prognostic accuracy using the ALBI grade was better in overall survival (OS) and relapse‐free survival (RFS), but in the low PLT group, the Child‐Pugh score was the more accurate model in OS and RFS. Conclusions Depending on the degree of fibrosis or preoperative PLT, the ALBI grade and Child‐Pugh score may provide more accurate prognoses after initial hepatectomy in HCC patients with Child‐Pugh A., Depending on the degree of fibrosis and preoperative platelet count (PLT), the albumin‐bilirubin (ALBI) grade or Child‐Pugh score may provide more accurate prognoses after initial hepatectomy in HCC patients with Child‐Pugh A.

Summary Objective The purpose of this study was to determine whether TAE negatively impacted perioperative outcomes in patients who underwent open surgery for pelvic trauma. Methods We retrospectively reviewed the medical records and radiographs of patients who had open surgery for an acute pelvic trauma between February 2014 and May 2017. The patients were classified into two groups: those who underwent TAE and those who did not. We evaluated preoperative demographics and perioperative outcomes between the two groups. Injury type-specific comparisons were also performed. Results A total of 136 patients (50 TAE and 86 non-TAE) were included in this study. There were significant differences in preoperative demographics including the type of injury, injury severity score, revised trauma score, surgical approach, initial blood pressure, and the amount of transfusion within 24 h between the two groups. However, no differences in perioperative outcomes were identified except for the amount of total transfusion. There were significant differences between the two groups in the injury type-specific comparisons, specifically in the amount of transfusion within 24 h in patients with pelvic ring injury and in the injury severity score in patients with acetabular fracture. However, there was no difference in perioperative outcomes between the groups for either injury type. Conclusion In the present study, we were unable to identify negative effects of TAE on perioperative outcomes. Therefore, when considering open surgery subsequent to TAE, there is no evidence of increased risk for negative perioperative outcomes, especially with respect to bone healing and deep infection.

Background Two surgical strategies are available for appendicitis: emergency laparoscopic appendectomy and interval laparoscopic appendectomy. However, timing of surgical intervention remains debatable. This study aimed to compare the surgical outcomes of emergency laparoscopic appendectomy and interval laparoscopic appendectomy and conduct a questionnaire survey to investigate the use of emergency laparoscopic appendectomy and patient satisfaction with regard to treatment. Methods We included 162 patients who underwent laparoscopic appendectomy at our hospital. Outcomes were assessed by operation time, blood loss, postoperative fasting time, length of hospital stay, and complication rate. Patient satisfaction was measured by questionnaire addressing degree of satisfaction, presurgery anxiety, and length of hospital stay. Results Of 162 patients, 74 (46%) and 88 (54%) received emergency and interval laparoscopic appendectomy, respectively. No significant difference was observed in the operation time, blood loss, length of hospital stay, or complication rate. Among 66 patients who responded to the questionnaire (28 emergency, 38 interval), a significant difference was observed only in the degree of satisfaction regarding the timing of the surgical intervention (p = 0.04). Conclusion Surgical outcomes of emergency and interval appendectomy were equivalent; however, patient satisfaction favored emergency appendectomy, suggesting it is a preferable approach for the treatment of uncomplicated appendicitis.

Summary Objective This study aimed to evaluate management and prognosis in children with pheochromocytoma who were treated at an Egyptian tertiary center. Methods The authors conducted an 8-year retrospective analysis for 17 patients who were presented from January 2013 to January 2021. Clinical criteria, operative details, and follow-up data were assessed. Overall (OS) and event-free survival (EFS) were estimated by the Kaplan–Meier method. An event was assigned with the occurrence of recurrence or metachronous disease, or death. Results Median age at diagnosis was 14 years (range: 6–17.5 years). Ten patients (58.8%) were males and seven (41.2%) were females. Hypertension-related symptoms were the main presentations in 15 patients (88%). None of the included children underwent genetic testing. Sixteen patients (94%) had unilateral tumors (right side: 12), whereas only one was presented with bilateral masses. The median tumor size was 7 cm (range: 4–9 cm). Metastatic workup did not reveal any metastatic lesions. All patients underwent open adrenalectomy, and clinical manifestations were completely resolved after surgery. Adjuvant therapy was not administered to any patient. There were no deaths or relapses at a median follow-up time of 40 months, whilst two children had metachronous disease after primary resection. Both were managed by adrenal-sparing surgery, and they achieved a second complete remission thereafter. Five-year OS and EFS were 100% and 88%, respectively. Conclusions Complete surgical resection achieves excellent clinical and survival outcomes for pheochromocytoma in children. Meticulous, long-term follow-up is imperative for early detection of metachronous disease to facilitate adrenal-sparing surgery. Genetic assessment for patients and their families is essential; however, it was not available at our institution.

Background The objective of this study was to identify the predictors of the conservative management outcomes in patients with lumbar herniated nucleus pulposus (HNP). Methods A prospective study was conducted between June 2010 and April 2012 in Banda Aceh, Indonesia. Clinical and baseline neurologic examinations such as passive straight leg raising test (SLRT), cross SLRT, and patellar and Achilles reflexes were assessed prior to the conservative management. The patients were evaluated at 2nd, 4th, 8th, 12th and 24th week following commencement of the conservative management. Results We recruited and followed 171 HNP patients of which 35.7% of them had good outcome. At univariate analysis, patients with more than 12 months duration of complaint, those with dominant radicular pain, severe pain intensity (visual analogue scale 7–10), positive SLRT, positive cross SLRT, and reduced motor power of knee extensors (muscle strength grade 1–4), were associated with poor outcome. Multivariate analysis suggested that patients with dominant radicular type of pain were likely to had poor outcome compared to those with dominant back pain (odd ratio (OR) 10.57 with 95% confidence interval (CI) 1.15–96.93). Patients with reduced motor power of knee extensors also had a higher chance to have poor outcome compared to those who were normal (OR: 10.57; 95% CI: 1.15–96.93). Conclusion Type of pain and the strength of lower extremities could be able to predict the failure of conservative management in patients with lumbar disc herniation. However, further studies with the bigger sample size are warrant to validate our results.
