Background: Transesophageal echocardiography (TEE) is mandatory before transvenous lead extraction (TLE), but its usefulness remains underestimated. This study aims to describe the broad range of TEE findings in TLE candidates, as well as their influence on procedure complexity, major complications (MCs) and long-term survival. Methods: Preoperative TEE was performed in 1191 patients undergoing TLE. Results: Lead thickening (OR = 1.536; p = 0.007), lead adhesion to heart structures (OR = 2.531; p < 0.001) and abnormally long lead loops (OR = 1.632; p = 0.006) increased the complexity of TLE. Vegetation-like masses on the lead (OR = 4.080; p = 0.44), lead thickening (OR = 2.389; p = 0.049) and lead adhesion to heart structures (OR = 6.341; p < 0.001) increased the rate of MCs. The presence of vegetations (HR = 7.254; p < 0.001) was the strongest predictor of death during a 1-year follow-up period. Conclusions: TEE before TLE provides a lot of important information for the operator. Apart from the visualization of possible vegetations, it can also detect various forms of lead-related scar tissue. Build-up of scar tissue and the presence of long lead loops are associated with increased complexity of the procedure and risk of MCs. Preoperative TEE performed outside the operating room may have an impact on the clinical decision-making process, such as transferring potentially more difficult patients to a more experienced center or having the procedure performed by the most experienced operator. Moreover, the presence of masses or vegetations on the leads significantly increases 1-year and all-cause mortality. [ABSTRACT FROM AUTHOR]

Abstract Background Delayed gastric emptying (DGE) commonly occurs after pancreaticoduodenectomy (PD). Risk factors for DGE have been reported in open PD but are rarely reported in laparoscopic PD (LPD). This study was designed to evaluate the perioperative risk factors for DGE and secondary DGE after LPD in a single center. Methods This retrospective cohort study included patients who underwent LPD between October 2014 and April 2023. Demographic data, preoperative, intraoperative, and postoperative data were collected. The risk factors for DGE and secondary DGE were analyzed. Results A total of 827 consecutive patients underwent LPD. One hundred and forty-two patients (17.2%) developed DGE of any type. Sixty-five patients (7.9%) had type A, 62 (7.5%) had type B, and the remaining 15 (1.8%) had type C DGE. Preoperative biliary drainage (p = 0.032), blood loss (p = 0.014), and 90-day any major complication with Dindo-Clavien score ≥ III (p

Background: Sarcopenia is highly prevalent among patients with colorectal cancer (CRC). Computed tomography (CT)‐based assessment of low skeletal muscle index (SMI) is widely used for diagnosing sarcopenia. However, there are conflicting findings on the association between low SMI and overall survival (OS) in CRC patients. The objective of this study was to investigate whether CT‐determined low SMI can serve as a valuable prognostic factor in CRC. Methods: We collected data from patients with CRC who underwent radical surgery at our institution between June 2020 and November 2021. The SMI at the third lumbar vertebra was calculated using CT scans, and the cutoff values for defining low SMI were determined using receiver operating characteristic curves. Univariate and multivariate analyses were performed to assess the associations between clinical characteristics and postoperative major complications. Results: A total of 464 patients were included in the study, 229 patients (46.7%) were classified as having low SMI. Patients with low SMI were older and had a lower body mass index (BMI), a higher neutrophil to lymphocyte ratio (NLR), and higher nutritional risk screening 2002 (NRS2002) scores compared to those with normal SMI. Furthermore, patients with sarcopenia had a higher rate of major complications (10.9% vs. 1.3%; p < 0.001) and longer length of stay (9.09 ± 4.86 days vs. 8.25 ± 3.12 days; p = 0.03). Low SMI and coronary heart disease were identified as independent risk factors for postoperative major complications. Moreover, CRC patients with low SMI had significantly worse OS. Furthermore, the combination of low SMI with older age or TNM stage II + III resulted in the worst OS in each subgroup analysis. Conclusions: CT‐determined low SMI is associated with poor prognosis in patients with CRC, especially when combined with older age or advanced TNM stage. [ABSTRACT FROM AUTHOR]

Background: Delayed gastric emptying (DGE) commonly occurs after pancreaticoduodenectomy (PD). Risk factors for DGE have been reported in open PD but are rarely reported in laparoscopic PD (LPD). This study was designed to evaluate the perioperative risk factors for DGE and secondary DGE after LPD in a single center. Methods: This retrospective cohort study included patients who underwent LPD between October 2014 and April 2023. Demographic data, preoperative, intraoperative, and postoperative data were collected. The risk factors for DGE and secondary DGE were analyzed. Results: A total of 827 consecutive patients underwent LPD. One hundred and forty-two patients (17.2%) developed DGE of any type. Sixty-five patients (7.9%) had type A, 62 (7.5%) had type B, and the remaining 15 (1.8%) had type C DGE. Preoperative biliary drainage (p = 0.032), blood loss (p = 0.014), and 90-day any major complication with Dindo-Clavien score ≥ III (p < 0.001) were independent significant risk factors for DGE. Seventy-six (53.5%) patients were diagnosed with primary DGE, whereas 66 (46.5%) patients had DGE secondary to concomitant complications. Higher body mass index, soft pancreatic texture, and perioperative transfusion were independent risk factors for secondary DGE. Hospital stay and drainage tube removal time were significantly longer in the DGE and secondary DGE groups. Conclusion: Identifying patients at an increased risk of DGE and secondary DGE can be used to intervene earlier, avoid potential risk factors, and make more informed clinical decisions to shorten the duration of perioperative management.

Background: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is the standard of care for selected cases of peritoneal surface malignancy. However, due to its morbidity and learning curve, it is only delivered in six centres in Australia and Aotearoa New Zealand (AoNZ). In this study, we report peri‐operative morbidity and mortality following CRS/HIPEC at Waikato and Braemar Hospitals, which have treated patients from all regions of AoNZ since 2008. Methods: We retrospectively reviewed a database of all patients undergoing CRS and HIPEC from 01/01/2008 to 01/11/2020 at Waikato and Braemar Hospitals. Results: Two‐hundred and forty procedures were performed for 221 patients with a mean age of 55, including 22 (9.2%) re‐do procedures. One hundred and eighty‐six cases were European, 32 were Māori, and 16 were Pasifika. There were 152 pseudomyxoma peritonei, 39 colorectal adenocarcinomas, 29 appendiceal cancers, 8 ovarian cancers, 6 peritoneal mesothelioma, and 6 other tumour types. The median PCI was 16. HIPEC was administered to 196 out of 196 CC0/1 cases (100%) and 3 out of 44 CC2/3 cases (6.8%). Fifty‐six cases (23.3%) had at least one major complication. There were two mortalities (0.8%) within 30 days. The median length of stay was 11 days. Operative duration was identified as an independent risk factor for major complications. There was considerable variation in the number of referrals from different regions of AoNZ. Over time, a decline in major complication rate is seen with increased case volume. Conclusion: The Waikato region has achieved favourable short‐term outcomes following CRS/HIPEC. [ABSTRACT FROM AUTHOR]

Total ankle arthroplasty (TAA) is an effective treatment for various ankle pathologies, but some concern remains for the high associated complication and failure rates relative to major joint arthroplasty of the hip and knee. Patient body mass index (BMI) is a modifiable and potentially important preoperative variable when evaluating postoperative complications. The purpose of this study is to evaluate the effect of BMI, age and sex on the acute postoperative complication rate after TAA. We retrospectively reviewed adult patients who underwent TAA between 2006 and 2021 from the NSQIP database. Using overweight patients as the reference BMI group, we utilized log-binomial models to estimate risk ratios on outcomes while adjusting for sex and age to investigate whether there were significant adjusted differences in complication rates among the BMI groups. We found that, relative to overweight patients, there were no statistically significant differences in the risk of acute complications for underweight (BMI < 18.5) (P =.118), healthy weight (18.5 ≤ BMI < 25) (P =.544), obese (30 ≤ BMI < 40) (P =.930), or morbidly obese (BMI < 40) (P =.602) patients who underwent TAA. There were also no statistically significant differences in the risk of acute complications based on age category (P =.482,.824) or sex (P =.440) for TAA. Additionally, there were no significant differences between the BMI groups for either major complications (P =.980) or minor complications (P =.168). Ultimately, we found that BMI, age, and sex did not lead to statistically significant differences in the risk of complications within 30 days postoperatively for TAA, even when stratified by major vs minor complications.

To investigate the incidence of preoperative abnormal iron status and its association with packed red blood cell (PRBC) transfusion, postoperative major complications, and new onset of clinically significant disability in patients undergoing elective cardiac surgery. A prospective, observational multicenter cohort study. Three cardiac surgical centers in the Netherlands between 2019 and 2021. Recruitment was on hold between March and May 2020 due to COVID-19. A total of 427 patients aged 60 years and older who underwent elective on-pump cardiac surgery. The primary endpoint was a 30-day PRBC transfusion. Secondary endpoints were postoperative major complications within 30 days (eg, acute kidney injury, sepsis), and new onset of clinically significant disability within 120 days of surgery. Iron status was evaluated before surgery. Abnormal iron status was present in 45.2% of patients (n = 193), and most frequently the result of iron deficiency (27.4%, n = 117). An abnormal iron status was not associated with PRBC transfusion (adjusted relative risk [ARR] 1.2; 95% CI 0.9-1.8: p = 0.227) or new onset of clinically significant disability (ARR 2.0; 95% CI 0.9-4.6: p = 0.098). However, the risk of postoperative major complications was increased in patients with an abnormal iron status (ARR 1.7; 95% CI 1.1-2.5: p = 0.012). An abnormal iron status before elective cardiac surgery was associated with an increased risk of postoperative major complications but not with PRBC transfusion or a new onset of clinically significant disability.

Background: Postoperative complications after cranial or spine surgery are prevalent, and frailty can be a key contributing patient factor. Therefore, we evaluated frailty’s impact on 30-day mortality. We compared the discrimination for risk analysis index (RAI), modified frailty index-5 (mFI-5) and increasing patient age for predicting 30-day mortality. Methods: Patients with major complications following neurosurgery procedures between 2012- 2020 in the ACS-NSQIP database were included. We employed receiver operating characteristic (ROC) curve and examined discrimination thresholds for RAI, mFI-5, and increasing patient age for 30-day mortality. Independent relationships were examined using multivariable analysis. Results: There were 19,096 patients included in the study and in the ROC analysis for 30-day mortality, RAI showed superior discriminant validity threshold C-statistic 0.655 (95% CI: 0.644-0.666), compared to mFI-5 C-statistic 0.570 (95% CI 0.559-0.581), and increasing patient age C-statistic 0.607 (95% CI 0.595-0.619). When the patient population was divided into subsets based on the procedures type (spinal, cranial or other), spine procedures had the highest discriminant validity threshold for RAI (Cstatistic 0.717). Furthermore, there was a frailty risk tier dose response relationship with 30-day mortalityy (p

Abstract Background Previous studies have suggested that higher surgeon volume leads to improved perioperative outcomes for oncologic surgery; however, the effect of surgeon volumes on surgical outcomes might differ according to the surgical approach used. This paper attempts to evaluate the effect of surgeon volume on complications or cervical cancer in an abdominal radical hysterectomy (ARH) cohort and laparoscopic radical hysterectomy (LRH) cohort. Methods We conducted a population-based retrospective study using the Major Surgical Complications of Cervical Cancer in China (MSCCCC) database to analyse patients who underwent radical hysterectomy (RH) from 2004 to 2016 at 42 hospitals. We estimated the annualized surgeon volumes in the ARH cohort and in the LRH cohort separately. The effect of the surgeon volume of ARH or LRH on surgical complications was examined using multivariable logistic regression models. Results In total, 22,684 patients who underwent RH for cervical cancer were identified. In the abdominal surgery cohort, the mean surgeon case volume increased from 2004 to 2013 (3.5 to 8.7 cases) and then decreased from 2013 to 2016 (8.7 to 4.9 cases). The mean surgeon case volume number of surgeons performing LRH increased from 1 to 12.1 cases between 2004 and 2016 (P

Objectives: This study aimed to assess trends by evaluating the types and complications of hysterectomies performed for benign gynecological reasons at our clinic, which is one of the largest hospitals in Turkey. Materials and Methods: Hysterectomies performed for benign reasons at our gynecology and obstetrics clinic between January 1, 2015 and December 31, 2020 were retrospectively reviewed and included in the analysis. Of the 4288 patients who had undergone hysterectomy, 888 patients were excluded some reasons. The data of the remaining 3400 patients were analyzed. Results: For the 3400 patients, the hysterectomy methods performed were as follows: Total Abdominal Hysterectomy (TAH (60%, n = 2055), Total Laparoscopic Hysterectomy (TLH), (27%, n = 948), Vaginal Hysterectomy (VH), (8.9%, n = 302), Conversion from laparoscopy to laparotomy (L / S > LT). (1.4%, n = 49), Robotic hysterectomy (RH), (1%, n = 33), and Subtotal hysterectomy (SH), (0.4%, n = 13). The length of hospital stay was statistically significantly lower in the TLH group than in the TAH group (P < 0.05). A statistically significant and moderate correlation was noted between the length of hospital stay and the duration of operation (r: 0.68 P = 0.00). Conclusion: The ratio of TLH group among hysterectomy modalities has increased over the years. There are many factors that affect the surgeon's decision in determining the hysterectomy method.TLH is the first option in patients who are not suitable for vaginal hysterectomy.

Abstract Background Postoperative complications and mortality following laparotomy have remained high worldwide. Early postoperative risk stratification is essential to improve outcomes and clinical care. The surgical Apgar score (SAS) is a simple and objective bedside prediction tool that can guide a surgeon’s postoperative decision making. The objective of this study was to evaluate the performance of SAS in predicting outcomes in patients undergoing laparotomy at Mulago hospital. Method A prospective observational study was conducted among eligible adult patients undergoing laparotomy at Mulago hospital and followed up for 4 months. We collected data on the patient’s preoperative and intraoperative characteristics. Using the data generated, SAS was calculated, and patients were classified into 3 groups namely: low (8–10), medium (5–7), and high (0–4). Primary outcomes were in-hospital major complications and mortality. Data was presented as proportions or mean (standard deviation) or median (interquartile range) as appropriate. We used inferential statistics to determine the association between the SAS and the primary outcomes while the SAS discriminatory ability was determined from the receiver-operating curve (ROC) analysis. Results Of the 151 participants recruited, 103 (68.2%) were male and the mean age was 40.6 ± 15. Overall postoperative in-hospital major complications and mortality rates were 24.2% and 10.6%, respectively. The participants with a high SAS category had an18.4 times risk (95% CI, 1.9–177, p = 0.012) of developing major complications, while those in medium SAS category had 3.9 times risk (95% CI, 1.01–15.26, p = 0.048) of dying. SAS had a fair discriminatory ability for in-hospital major complications and mortality with the area under the curve of 0.75 and 0.77, respectively. The sensitivity and specificity of SAS ≤ 6 for major complications were 60.5% and 81.14% respectively, and for death 54.8% and 81.3%, respectively. Conclusion SAS of ≤ 6 is associated with an increased risk of major complications and/or mortality. SAS has a high specificity with an overall fair discriminatory ability of predicting the risk of developing in-hospital major complications and/or death following laparotomy.

Background: We conducted a prospective study of surgical inpatients at a teaching hospital to assess the incidence and potential risk factors for major complications of caudal anesthesia in anorectal surgery. Methods: A total of 973 patients undergoing anorectal surgery under caudal block were included in this prospective, observer-blinded trial after providing consent. Demographic information, detailed perioperative information, anesthesia-related complications and postoperative follow-up information were recorded. Meanwhile, the incidence and risk factors for major caudal anesthesia-related complications were analyzed. Results: A total of 973 patients underwent caudal block. The effective rate was 95.38 % (928 cases). However, there were still 38 (3.91 %) cases with insufficient block and 7 (0.72 %) cases with no block. The major anesthesia-related complications were local anesthetic systemic toxicity (9, 0.92 %), cauda equine syndrome (1, 0.10 %), transient neurological symptoms (3, 0.31 %) and localized pain at the caudal insertion site (30, 3.08 %). The identified risk factor for local anesthetic systemic toxicity was multiple attempts locating the caudal space (OR = 5.30; 1.21–23.29). The identified risk factor for localized pain at the caudal insertion site was multiple attempts locating the caudal space (OR = 10.57; 4.89–22.86). Conclusion: The main complications of caudal block in adult patients are transient neurological symptoms, cauda equine syndrome, serious local anesthetic systemic toxicity and localized pain at the caudal insertion site. Overall, the incidence of complications is low and symptoms are mild. Caudal block is still a safe and reliable method for anesthesia in adult anorectal surgery.

Abstract Aim Although major complication rates following percutaneous liver biopsy (PLB) have been reported to be higher in children than in adults, scarce data are available regarding pediatric patients stratified by native and transplanted liver. We aimed to assess the factors associated with major complications after percutaneous biopsy of native or transplanted liver using a nationwide inpatient database. Methods Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified pediatric patients who underwent PLB between 2010 and 2018. We described major complication rates and analyzed factors associated with major complications following PLB, stratified by native and transplanted liver. Results We identified 3584 pediatric PLBs among 1732 patients from 239 hospitals throughout Japan during the study period, including 1310 in the native liver and 2274 in the transplanted liver. Major complications following PLB were observed in 0.5% (n = 18) of the total cases; PLB in the transplanted liver had major complications less frequently than those in the native liver (0.2% vs. 1.0%, p = 0.002). The occurrence of major complications was associated with younger age, liver cancers, unscheduled admission, anemia or coagulation disorders in cases with native liver, while it was associated with younger age alone in cases with transplanted liver. Conclusions The present study, using a nationwide database, found that major complications occurred more frequently in pediatric cases with native liver and identified several factors associated with its major complications.

Background The known risks and benefits of native kidney biopsies are mainly based on the findings of retrospective studies. The aim of this multicentre prospective study was to evaluate the safety of percutaneous renal biopsies and quantify biopsy-related complication rates in Italy. Methods The study examined the results of native kidney biopsies performed in 54 Italian nephrology centres between 2012 and 2020. The primary outcome was the rate of major complications 1 day after the procedure, or for longer if it was necessary to evaluate the evolution of a complication. Centre and patient risk predictors were analysed using multivariate logistic regression. Results Analysis of 5304 biopsies of patients with a median age of 53.2 years revealed 400 major complication events in 273 patients (5.1%): the most frequent was a ≥2 g/dL decrease in haemoglobin levels (2.2%), followed by macrohaematuria (1.2%), blood transfusion (1.1%), gross haematoma (0.9%), artero-venous fistula (0.7%), invasive intervention (0.5%), pain (0.5%), symptomatic hypotension (0.3%), a rapid increase in serum creatinine levels (0.1%) and death (0.02%). The risk factors for major complications were higher plasma creatinine levels [odds ratio (OR) 1.12 for each mg/dL increase, 95% confidence interval (95% CI) 1.08–1.17], liver disease (OR 2.27, 95% CI 1.21–4.25) and a higher number of needle passes (OR for each pass 1.22, 95% CI 1.07–1.39), whereas higher proteinuria levels (OR for each g/day increase 0.95, 95% CI 0.92–0.99) were protective. Conclusions This is the first multicentre prospective study showing that percutaneous native kidney biopsies are associated with a 5% risk of a major post-biopsy complication. Predictors of increased risk include higher plasma creatinine levels, liver disease and a higher number of needle passes. [ABSTRACT FROM AUTHOR]

The effect of the surgeon volume of ARH or LRH on surgical complications was examined using multivariable logistic regression models. Results: In total, 22,684 patients who underwent RH for cervical cancer were identified. In the abdominal surgery cohort, the mean surgeon case volume increased from 2004 to 2013 (3.5 to 8.7 cases) and then decreased from 2013 to 2016 (8.7 to 4.9 cases). The mean surgeon case volume number of surgeons performing LRH increased from 1 to 12.1 cases between 2004 and 2016 (P < 0.01). In the abdominal surgery cohort, patients treated by intermediate-volume surgeons were more likely to experience postoperative complications (OR = 1.55, 95% CI = 1.11–2.15) than those treated by high-volume surgeons. In the laparoscopic surgery cohort, surgeon volume did not appear to influence the incidence of intraoperative or postoperative complications (P = 0.46; P = 0.13). Conclusions: The performance of ARH by intermediate-volume surgeons is associated with an increased risk of postoperative complications. However, surgeon volume may have no effect on intraoperative or postoperative complications after LRH. [ABSTRACT FROM AUTHOR]

Background: Although abdominoplasty is a safe and popular surgery, it is associated with a higher complication rate than other body contouring procedures. Therefore, identifying predictive factors of major and minor complications in patients who have undergone abdominoplasty is necessary to achieve better treatment outcomes after major weight loss. Methods: This retrospective study analyzed the medical records of patients who underwent abdominoplasty between January 2016 and December 2019. The inclusion criteria were patients aged >18 years who underwent abdominoplasty as the only surgical procedure and had adequate follow-up. Other patients were excluded from the study. Statistical evaluation was performed using SPSS 20.0; statistical significance was set at a P-value of

Objective: The objective of this study was to assess the complicated relationship between frailty, perioperative complications, and patient-reported outcomes (PROs) in elderly patients (≥ 75 years old) undergoing lumbar spine fusion (LSF)., Methods: Consecutive patients who underwent LSF between March 2019 and December 2021 were recruited in this study. Frail patients (modified frailty index [mFI] score ≥ 2) were propensity score matched to nonfrail patients (mFI score 0-1) on the basis of age, sex, and the number of fused levels. Perioperative complications were collected and assessed according to the comprehensive complication index. Subgroups were further subdivided on the basis of the presence of major complications. The data from SF-36, Oswestry Disability Index (ODI), and North American Spine Society Satisfaction Questionnaire (NASS) at baseline and 1- and 2-year follow-up evaluations were compared between groups. Furthermore, the minimal clinically important difference (MCID) achievement rate was also compared., Results: The final analysis included 631 patients: 344 in the frail group and 287 in the nonfrail group. Frail patients were older (79.7 ± 5.1 years vs 76.4 ± 4.8 years, p < 0.001), with a higher proportion of females (68.9% vs 57.8%, p = 0.004) and those with malnutrition (17.7% vs 11.1%, p = 0.020). After propensity score matching for age, sex, and number of fused levels, 402 patients (201 in each group) were analyzed. Frail patients were more prone to have delirium (7.5% vs 3.0%, p = 0.044), blood transfusion (43.3% vs 30.3%, p = 0.007), and surgical site infection (6.0% vs 2.0%, p = 0.041). In addition, frail patients had a higher proportion of major complications (29.4% vs 16.9%, p = 0.003). Although they had worse PROs at baseline, frail patients obtained higher mean improvements and higher rates of MCID achievement by the 1- and 2-year follow-up evaluations than their nonfrail counterparts. Major complications did not seem to affect PROs in frail and nonfrail patients., Conclusions: Despite being associated with worse baseline PROs, frail patients gained greater mean improvement in PROs and higher rates of MCID achievement by the 1- and 2-year follow-up evaluations than nonfrail patients. In addition, the presence of major complications did not affect PROs at the 1- and 2-year follow-ups. Although associated with major complications, elderly patients with frailty could benefit from LSF.

Background Context: The number of elderly patients with degenerative spinal deformity (DSD) is increasing, and posterior thoracolumbar fusion surgery is an effective treatment option, but there are often postoperative major complications, which may hinder the benefit for elderly patients. Currently, there is no consensus on the best risk assessment technique for predicting major complications in elderly patients undergoing long-segment fusion surgery., Purpose: This study constructs a risk assessment model using the Modified 5-Item Frailty Index (mFI-5) and serum albumin and evaluates its predictive value., Study Design: This is a retrospective analysis of a prospectively established database of DSD., Patient Sample: Consecutive patients (aged 65 and older) who underwent open posterior thoracolumbar fusion surgery for DSD between April 2018 and December 2023 were included., Outcome Measures: Outcome measures included postoperative major complications, length of hospital stay [LOS], readmission and reoperation within 30 days, discharge disposition, physiological function recovery., Methods: The study reviewed consecutive patients who underwent open posterior thoracolumbar fusion surgery for DSD. Patients were divided into three groups based on the presence or absence of frailty or frailty combined with malnutrition. Spearman ρ analysis was used to assess the correlation between mFI-5 and serum albumin levels. Univariate analyses and multivariate logistic regression were conducted to explore the relationship between frailty and malnutrition defined by mFI-5 and serum albumin and major postoperative complications. Finally, the Receiver Operating Characteristic (ROC) curve was used to evaluate the predictive value of this model for major complications., Results: Compared to the Normal group (n=59), both the Frailty group (n=121) and the Frailty and Malnutrition group (n=50) had higher rates of major complications (21.5% vs. 8.5%, p=.035; 28% vs. 8.5%, p=.002). Multivariate logistic regression showed that frailty and malnutrition status, higher ASA score, and more bleeding were independent predictors of major postoperative complications. The ROC curve demonstrated that frailty combined with malnutrition defined by mFI-5 and serum albumin had a larger area under the curve compared to mFI-5 or serum albumin alone (AUC: 0.676; 95% CI: 1.101-14.129; p<.001)., Conclusions: Compared to considering frailty or malnutrition alone, the combined assessment of frailty and malnutrition using mFI-5 and serum albumin is valuable in predicting major complications in elderly patients undergoing posterior thoracolumbar fusion surgery., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Introduction: Open abdominal aortic aneurysm (AAA) surgery is associated with significant morbidity, mortality and high length of stay (LOS). Enhanced recovery is now commonplace and has been shown to decrease these in other non-vascular surgery settings. This systematic review and meta-analysis aimed to assess the benefits of enhanced recovery (ERAS) in aortic surgery. Method: Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used to undertake a systematic review via Ovid MEDLINE and Embase on 10.07.2021. The search terms were "aortic aneurysm" and "fast track" or "enhanced recovery". Data was obtained on major complications, 30-day mortality and LOS. Results: 107 papers were identified and 10 papers included for meta-analysis. Complication rates were significantly reduced with ERAS compared to non-ERAS protocols (ERAS n = 709, non-ERAS n = 930) (odds ratio.38,.22 to.65: P =.0005). LOS was also significantly reduced with an ERAS protocol (ERAS n = 708, non-ERAS n = 956) with a mean reduction of 3.18 days (−5.01 to −1.35 days) (P =.0007: I2 = 97%). There was no significant difference however in 30-day mortality (P =.92). Conclusion: This meta-analysis demonstrates significant benefits to an enhanced recovery programme in open AAA surgery. There is a need for a multi-centre randomized controlled trial to assess this further. [ABSTRACT FROM AUTHOR]

Background: Current diagnostic criteria for cancer cachexia are inconsistent, and arguments still exist about the impact of cachexia on the survival of patients with colorectal cancer. In this study, we aim to investigate the prognostic value of a novel cachexia indicator, the cachexia index (CXI), in patients with colorectal cancer. Methods: The CXI was calculated as skeletal muscle index (SMI) × serum albumin/neutrophil-lymphocyte ratio. The cut-off value of CXI was determined by the receiver operating characteristic (ROC) curves and Youden's index. The major outcomes were major complications, overall survival (OS), and recurrence-free survival (RFS). Results: A total of 379 patients (234 men and 145 women) were included. The ROC curves indicated that CXI had a significantly diagnostic capacity for the detection of major complications. Based on Youden's index, there were 231 and 148 patients in the low and high CXI groups, respectively. Patients in the low CXI group had significantly older age, lower BMI, and a higher percentage of cachexia and TNM stage II+III. Besides, Patients in low CXI group were associated with a significantly higher rate of major complications, blood transfusion, and longer length of stay. Logistic regression analysis indicated that low CXI, cachexia, and coronary heart disease were independent risk factors for the major complications. Kaplan Meier survival curves indicated that patients with high CXI had a significantly more favorable OS than those with low CXI, while no significant difference was found in RFS between the two groups. Besides, there were no significant differences in OS or RFS between patients with and without cachexia. The univariate and multivariate Cox regression analysis indicated that older age, low CXI, and coronary heart disease instead of cachexia were associated with a decreased OS.Conclusion: CXI was better than cachexia in predicting OS and could be a useful prognostic indicator in patients with colorectal cancer, and greater attention should be paid to patients with low CXI.

Aim: Although major complication rates following percutaneous liver biopsy (PLB) have been reported to be higher in children than in adults, scarce data are available regarding pediatric patients stratified by native and transplanted liver. We aimed to assess the factors associated with major complications after percutaneous biopsy of native or transplanted liver using a nationwide inpatient database.Methods: Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified pediatric patients who underwent PLB between 2010 and 2018. We described major complication rates and analyzed factors associated with major complications following PLB, stratified by native and transplanted liver.Results: We identified 3584 pediatric PLBs among 1732 patients from 239 hospitals throughout Japan during the study period, including 1310 in the native liver and 2274 in the transplanted liver. Major complications following PLB were observed in 0.5% (n = 18) of the total cases; PLB in the transplanted liver had major complications less frequently than those in the native liver (0.2% vs. 1.0%, p = 0.002). The occurrence of major complications was associated with younger age, liver cancers, unscheduled admission, anemia or coagulation disorders in cases with native liver, while it was associated with younger age alone in cases with transplanted liver.Conclusions: The present study, using a nationwide database, found that major complications occurred more frequently in pediatric cases with native liver and identified several factors associated with its major complications.

BackgroundTo assess the frequency of major complications after thermal ablation of liver tumours and to determine risk factors for adverse events.MethodsA retrospective study was conducted between January 2015 and January 2021. A total of 2,084 thermal ablation sessions in 1,592 patients with primary and metastatic liver tumours were evaluated. The frequency of major complications was evaluated according to the Society of Interventional Radiology Standards, and putative predictors of adverse events were analysed using simple and multivariate logistic regression.ResultsThermal ablation-related mortality was 0.1% (2/2,084), with an overall major complication rate of 5.6% (117/2,084). The most frequent major complication was symptomatic pleural effusion (2.9%, 60/2,084). Multivariate logistic regression analysis revealed that a total maximum diameter of lesions >3 cm, microwave ablation (MWA) and MWA combined with radiofrequency ablation, intrahepatic cholangiocarcinoma and postoperative systemic inflammatory response syndrome were independent prognostic factors for major complications.ConclusionsThermal ablation of liver tumours is a safe procedure with an acceptable incidence of major complications. The risk factors identified in this study will help to stratify high-risk patients.

Abstract Background Cochlear implantation (CI) has been established worldwide as the surgical treatment for individuals with bilateral severe to profound hearing loss. Complications due to surgery are minimal and are often encountered in cases with congenital anomalies of the temporal bone and inner ear. Complications in CI are related to malfunctioning of the device or the process of wound healing. In most cochlear implant centers, as the surgeon’s skill and clinical expertise in managing various cochlear implant cases improve with years of experience, the complication rates ideally come down over time. This article is intended to describe the most common surgical complications of cochlear implantation in Zagazig University Hospitals. This retrospective study included 130 patients who underwent cochlear implantation in Zagazig University Hospitals from 2016 to 2018. The patients were 61 males and 69 females; their ages ranged between 2 and 6 years old with a mean age of 4.3. This study aims to provide feedback on the common complications of CI surgery at our institution to help the reduction of its incidence in the future. Results One hundred thirty cases of cochlear implants were performed in our department between 2016 and 2018. Sixty complications were recorded, including 27 cases of minor and 21 cases of major complications. Minor complications were flap wound infection in 4 cases (3.1%), chorda tympani nerve injury in 7 cases (5.4%), postoperative vertigo and vomiting in 3 cases (2.3%), injury of EAC in 7 cases (5.4%), wound seroma/hematoma in 4 cases (3.1%), and facial nerve twitching in 2 cases (1.5%). Major complications were electrode extrusion in 2 cases (1.5%), CSOM in 1 case (0.8%), CSF leak in 8 cases (6.1%), magnet migration in 3 cases (2.3%), total facial nerve paralysis in 5 cases (3.8%), and device failure in 2 cases (1.5%). Conclusion The overall incidence of major complications is low. The majority of minor complications can be effectively managed with conservative measures. Cochlear implantation remains a safe and effective surgical procedure.

Abstract Background and Aim Percutaneous endoscopic gastrostomy (PEG) has been used in patients with dysphagia and inadequate food intake via an oral route. Despite being a procedure with a high success rate, complications and death have been reported. The aim was to identify the factors related to major complications and mortality, as well as PEG removal prognostic factors due to improvement of their general condition. Methods Patient characteristics, comorbidities, laboratory data, concomitant medication, sedation, and indication for PEG placement were collected. Major complications, mortality, and PEG removal factors were assessed. Results A total of 388 patients were enrolled. There were 15 (3.9%) cases of major complications, with major bleeding being the most frequent in 6 (1.5%) patients. Corticosteroids were the independent variable associated with major complications (odds ratio [OR] 5.85; 95% confidence interval [CI] 1.71–20; P =

BackgroundAlthough many studies reported the effectiveness of transarterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) or surgical resection (SR) in the treatment of hepatocellular carcinoma (HCC), the efficacy of these two strategies remains controversial. Therefore, this meta-analysis aimed to evaluate and compare the efficacy of sequential use of TACE plus RFA (TACE + RFA) and SR alone in treating HCC.MethodsRelevant studies with unmatched and propensity score-matched patients were identified by comprehensive search of MEDLINE, PubMed, EMBASE, Web of Science, and Cochrane electronic databases. Meta-analysis was conducted using Review Manager (RevMan) software version 5.4.1. Finally, 12 eligible studies were included in this study, including 11 case–control studies and 1 randomized controlled trial. The primary outcome of interest for this study was to compare the 1-, 3-, and 5-year overall survival (OS) and disease-free survival (DFS), major complications, 5-year OS in different tumor diameters between the two treatment strategies, and hospital stay time.ResultsHCC patients who received TACE + RFA had a lower incidence of complication rates and shorter hospital stay time than those who received SR alone. Among these studies using propensity score-matched cohorts, SR had better 3- and 5-year OS than TACE + RFA, whereas there were no significant differences between TACE + RFA and SR regarding the 1-, 3-, and 5-year DFS. When the tumor diameter is longer than 3 cm, the 5-year OS rate is better when SR is selected.ConclusionThere was no significant difference in the short-term survival outcomes between TACE + RFA and SR in HCC patients. Moreover, SR is superior to TACE + RFA in terms of long-term beneficial effects but may result in a higher risk of major complications and a longer hospital stay time.

Background and ObjectiveTransjugular intrahepatic portosystemic shunt (TIPS) is a well-established procedure for treating complications of portal hypertension. Due to the complexity of anatomy and difficulty of the puncture technique, the procedure itself might brought potential complications, such as puncture failure, bleeding, infection, and, rarely, death. The aim of this study is to explore the incidence, management, and outcome of TIPS procedure-related major complications using covered stents.MethodsPatients who underwent TIPS implantation from January 2015 to December 2020 were recruited retrospectively. Major complications after TIPS were screened and analyzed.ResultsNine hundred and forty-eight patients underwent the TIPS procedure with 95.1% (n = 902) technical success in our department. TIPS procedure-related major complications occurred in 30 (3.2%) patients, including hemobilia (n = 13; 1.37%), hemoperitoneum (n = 7; 0.74%), accelerated liver failure (n = 6; 0.63%), and rapidly progressive organ failure (n = 4; 0.42%). Among them, 8 patients died because of hemobilia (n = 1), accelerated liver failure (n = 4), and rapidly progressive organ failure (n = 3).ConclusionThe incidence of major complications related to TIPS procedure is relatively low, and some of them could recover through effective medical intervention. In our cohort, the overall incidence is about 3%, which causes 0.84% death. The most fatal complication is organ failure and hemobilia.

To compare the oncological outcomes and major complications of laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) for stage IB1 cervical cancer (FIGO 2009) with a tumour size less than 2 cm. We retrospectively compared the oncological outcomes and major complications of 1207 stage IB1 cervical cancer patients with a tumour size less than 2 cm who received LRH (n = 546) or ARH (n = 661) in 37 hospitals. (1) There was no significant difference in 3-year overall survival (OS; 97.3% vs. 98.5%, P = 0.288) or 3-year disease-free survival (DFS; 95.1% vs. 95.4%, P = 0.792) between LRH (n = 546) and ARH (n = 661).(2) The rate of any 1 complication refers to the incidence of one or more complications in a patient, which was higher with LRH than ARH (OR = 4.047, 95% CI = 2.035–8.048, P < 0.001). Additionally, intraoperative complications occurred with LRH (OR = 12.313, 95% confidence intervals [CI] = 1.571–96.493, P = 0.017), and postoperative complications (OR = 3.652, 95% CI = 1.763–7.562, P < 0.001) were higher with LRH than ARH. The ureteral injury rate was higher with LRH than with ARH (1.50% vs. 0.20%, OR = 9.814, 95% CI = 1.224–78.712, P = 0.032). The ureterovaginal fistula rate was higher with LRH than ARH. The rates of obturator nerve injury, bladder injury, vesicovaginal fistula, rectovaginal fistula, venous thromboembolism, bowel obstruction, chylous leakage, pelvic haematoma, and haemorrhage were similar between the groups. The oncological outcomes of LRH and ARH for stage IB1 cervical cancer patients with a tumour size less than 2 cm do not differ significantly. However, incidences of any 1 complication, intraoperative complications, and postoperative complications were higher with LRH than ARH, with complications manifesting mainly as ureteral injury and uterovaginal fistula. (1) We compared the oncological outcomes and major complications of laparoscopic radical hysterectomy (LRH) and abdominal radical hysterectomy (ARH) for stage IB1 cervical cancer patients (FIGO 2009) with a tumour size less than 2 cm. (2) There was no significant difference in oncological outcome between LRH and ARH. (3) The incidences of any 1 complication, intraoperative complications and postoperative complications were higher with LRH than ARH, with complications manifesting mainly as ureteral injury and uterovaginal fistula.

Background and Aim: Percutaneous endoscopic gastrostomy (PEG) has been used in patients with dysphagia and inadequate food intake via an oral route. Despite being a procedure with a high success rate, complications and death have been reported. The aim was to identify the factors related to major complications and mortality, as well as PEG removal prognostic factors due to improvement of their general condition. Methods: Patient characteristics, comorbidities, laboratory data, concomitant medication, sedation, and indication for PEG placement were collected. Major complications, mortality, and PEG removal factors were assessed. Results: A total of 388 patients were enrolled. There were 15 (3.9%) cases of major complications, with major bleeding being the most frequent in 6 (1.5%) patients. Corticosteroids were the independent variable associated with major complications (odds ratio [OR] 5.85; 95% confidence interval [CI] 1.71–20; P = <0.01). Advanced cancer (hazard ratio [HR] 0.5; 95% CI 0.3–1; P = 0.05), albumin (HR 0.6; 95% CI 0.4–0.9; P = <0.01), and C‐reactive protein (CRP) (HR 1.1; CI 1–1.2; P = 0.01) were considered risk factors for mortality. Previous pneumonia (HR 0.4; CI 0.2–0.9; P = 0.02) was a factor for permanent use of a PEG; however, oncological indication (HR 8.2; CI 3.2–21; P = <0.01) was factors for PEG withdrawal. Conclusions: Chronic corticosteroid users potentially present with major complications. Low albumin levels and elevated CRP were associated with death. Previous aspiration pneumonia was a factor associated with permanent use of PEG; however, patients with oncological indication were the most benefited. [ABSTRACT FROM AUTHOR]

Background: Comminuted, markedly displaced distal radius fractures can cause instability requiring advanced stabilization with dorsal bridge plating. However, published complication rates of bridge plating widely vary. We hypothesize that complications of bridge plating of distal radius fractures are more prevalent than published rates., Methods: A retrospective review was performed on all patients at an academic level I trauma center treated with a bridge plate for a distal radius fracture from 2014 to 2022., Results: Sixty-five wrists were included in the final analysis: average age 53 years, male 51%, average plate retention 4 months, and average follow-up 6 months. Carpal tunnel release (CTR) was performed at time of primary procedure in 7 (10%) cases. Radial height, radial inclination, dorsal tilt, and ulnar variance were all significantly improved ( P < .001). Grip strength, flexion, extension, and supination were significantly limited ( P < .03). Twenty-one patients (32%) developed 35 major complications requiring unplanned reoperation, including mechanical hardware-related complication (15%), deep infection (11%), nonunion/delayed union (9%), adhesions (6%), median neuropathy (6%), symptomatic arthritis (5%), and tendon rupture (2%). Plate breakage occurred in 3 patients (5%) and was always localized over the central drill holes of the bridge plate., Conclusions: Major complications for bridge plating of distal radius fractures were higher at our institution than previously published. Plate breakage should prompt reconsideration of plate design to avoid drill holes over the wrist joint. Signs and symptoms of carpal tunnel syndrome should be carefully assessed at initial presentation, and consideration for concomitant CTR should be strongly considered., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: The aim of this study was to evaluate correlation between centers’ volume and incidence of failure to rescue (FTR) following liver resection for hepatocellular carcinoma (HCC). Summary Background Data: FTR, defined as the probability of postoperative death among patients with major complication, has been proposed to assess quality of care during hospitalization. Perioperative management is challenging in cirrhotic patients and the ability to recognize and treat a complication may be fundamental to rescue patients from the risk of death. Methods: Patients undergoing liver resection for HCC between 2008 and 2018 in 18 Centers enrolled in the He.Rc.O.Le.S. Italian register. Early results included major complications (Clavien 3), 90-day mortality, and FTR and were analyzed according to center’s volume. Results: Among 1935 included patients, major complication rate was 9.4% (8.6%, 12.3%, and 7.0% for low-, intermediate- and high-volume centers, respectively, P - 0.001). Ninety-day mortality rate was 2.6% (3.7%, 4.2% and 0.9% for low-, intermediate- and high-volume centers, respectively, P < 0.001). FTR was significantly higher at low- and intermediate-volume centers (28.6% and 26.5%, respectively) than at high-volume centers (6.1%, P = 0.002). Independent predictors for major complications were American Society of Anesthesiologists (ASA) >2, portal hypertension, intraoperative blood transfusions, and center’s volume. Independent predictors for 90-day mortality were ASA >2, Child-Pugh score B, BCLC stage B-C, and center’s volume. Center’s volume and BCLC stage were strongly associated with FTR. Conclusions: Risk of major complications and mortality was related with comorbidities, cirrhosis severity, and complexity of surgery. These factors were not correlated with FTR. Center’s volume was the only independent predictor related with severe complications, mortality, and FTR. [ABSTRACT FROM AUTHOR]

Background Renal biopsies are essential in nephrology but they are invasive and complications can occur. The aim of this study was to explore clinical parameters that can be used as predictors for biopsy complications. Methods Clinical parameters such as demographics, biopsy indications, serology, comorbidities and clinical chemistry were retrieved from a regional biopsy registry between 2006 and 2015 and from a nationwide registry between 2015 and 2017. Clinical data before biopsy were compared with data on major biopsy complications. Fisher's exact and χ 2 tests were used and odds ratios (ORs) with 95% confidence intervals (CIs) were presented. Univariate and multiple binary logistic regression analyses were performed with complications as outcome. A two-sided P-value <0.05 was considered significant. Results In total, 2835 consecutive native kidney biopsies were analysed (39% women and 61% men, median age 57 years). No death and nephrectomy due to biopsy complications were registered. The frequency of major biopsy complications was 5.65%. In the multiple logistic regression, the risk for complications increased in women [OR 1.51 (95% CI 1.08–2.11)] and decreased with age: 45–64 years age group [OR 0.66 (95% CI 0.44–0.99)] and >74 years age group [OR 0.51 (95% CI 0.27–0.96)]. Among comorbidities, patients with diabetes mellitus type 2 [OR 2.07 (95% CI 1.15–3.72)] and non-ischaemic heart disease [OR 3.20 (95% CI 1.64–6.25)] had a higher risk for major biopsy complications. Conclusions Female gender, younger age (≤44 years), diabetes mellitus type 2 and non-ischaemic heart disease were found as risk factors for major biopsy complications. [ABSTRACT FROM AUTHOR]

There is a paucity of robust clinical data on major postoperative complications following robotic-assisted resection for primary lung cancer. This study assessed the incidence and outcomes of patients who experienced major complications after robotic anatomic pulmonary resection. This was a multicenter, retrospective review of patients who underwent robotic anatomic pulmonary resection between 2002 and 2018. Major complications were defined as grade III or higher complications according to the Clavien–Dindo classification. Statistical analysis was performed based on patient-, surgeon-, and treatment-related factors. During the study period, 1264 patients underwent robotic anatomic pulmonary resections, and 64 major complications occurred in 54 patients (4.3%). Univariate analysis identified male sex, forced expiratory volume in 1 second, diffusion capacity of the lung for carbon monoxide, neoadjuvant therapy, and extent of resection as associated with increased likelihood of a major postoperative complication. Patient age, performance status, body mass index, reoperation status, and surgeon experience did not have a significant impact on major complications. Patients who experienced at least 1 major complication were at higher risk for an intensive care unit stay of >24 hours (17.0% vs 1.4%; P <.001) and prolonged hospitalization (8.5 days vs 4 days; P <.001). Patients who experienced a major postoperative complication had a 14.8% risk of postoperative death. In this series, the major complication rate during the postoperative period was 4.3%. A number of identified patient- and treatment-related factors were associated with an increased risk of major complications. Major complications had a significant impact on mortality and duration of stay. [ABSTRACT FROM AUTHOR]

Background: Variations in atmospheric pressure (AP) are known to affect blood pressure (BP). We assessed the effect of AP on BP, and the major fatal and nonfatal complications thereof (i.e., stroke, myocardial infarction, and pulmonary emboli). Methods: In this observational cohort study, 250 hypertensive patients (aged 65–92 years old) were followed for 3.5–5.4 years in a primary care clinic. Cox proportional hazard regression was performed to define the associations between AP, clinical, demographic and environmental factors, and major complications such as stroke, myocardial infarction, etc. Results: AP fluctuated between 1007 and 1024 millibars (MB). A total of 132 patients (53%) developed various complications, of which 13 (9.8%) were fatal. Among all fatalities, 93 of 119 nonfatal cases and 7 of 13 fatal cases occurred at AP < 1013 MB. A Cox regression analysis showed that low AP (AP < 1013 MB) had a higher hazard ratio (HR) on hypertension (HTN) complications among all demographic, clinical and environmental parameters. Conclusions: Most major complications were associated with very low APs. Low AP was the best predictive risk-factor for major complications of HTN.

To report the trends in surgical approaches and compare the major surgical complication rates of laparoscopic and abdominal radical hysterectomy for cervical cancer. From the major surgical complications of cervical cancer in China (MSCCCC) database, we obtained the demographic, clinical, treatment hospital and complication data of patients with cervical cancer who underwent radical hysterectomy from 2004 to 2015 at 37 hospitals. The patients were assigned to the laparoscopic and abdominal surgery groups. The differences in the complication rates were analyzed using univariate and multivariable logistic regression models. We identified a total of 18447 patients; 5491 (29.8%) underwent laparoscopic surgery and 12956 (70.2%) underwent abdominal surgery. The proportion of laparoscopic surgery rose from 0.35% in 2004 to 49.31% in 2015. In the multivariate analysis, the laparoscopic group had increased odds of intraoperative and postoperative complications (OR = 3.88, 95% CI = 2.47–6.11; OR = 1.42, 95% CI = 1.11–1.82). A more detailed analysis showed that laparoscopic surgery was associated with increased rates of intraoperative ureteral injury (OR = 3.83, 95% CI = 2.11–6.95), bowel injury (OR = 14.83, 95% CI = 1.32–167.25), vascular injury (OR = 3.37, 95% CI = 1.18–9.62), postoperative vesicovaginal fistula (OR = 4.16, 95% CI = 2.08–8.32), ureterovaginal fistula (OR = 4.16, 95% CI = 2.08–8.32), rectovaginal fistula (OR = 8.04, 95% CI = 1.63–39.53), and chylous leakage (OR = 10.65, 95% CI = 1.18–95.97), while abdominal surgery was more likely to cause bowel obstruction (OR = 0.55, 95% CI = 0.35–0.87). The two groups had similar rates of bladder injury, obturator nerve injury, pelvic hematoma, rectovaginal fistula and venous thromboembolism (P > 0.05). Laparoscopic surgery was associated with more major surgical complications, especially intraoperative ureteral injury and postoperative fistula, than abdominal surgery among women with cervical cancer. • The proportion of laparoscopic surgery rose significantly between 2004 and 2015. • Laparoscopic surgery was associated with a higher risk of major surgical complications than abdominal surgery. • Laparoscopic surgery was associated with more intraoperative ureteral injury and postoperative fistula.

Aims: We aimed at describing outcomes and predictors of cardiac avulsion or tear (CA/T) with tamponade and vascular avulsion or tear (VA/T) after transvenous lead extraction (TLE) in the ESC-EHRA European Lead Extraction ConTRolled (ELECTRa) registry.Methods and Results: A total of 3555 consecutive patients of whom 3510 underwent TLE at 73 centres in 19 European countries were enrolled. Among 58 patients (1.7%) with procedure-related major complications, 49 (84.5%) patients (30 CA/T and 19 VA/T) presented cardiovascular complications requiring pericardiocentesis, chest tube positioning and/or surgical repair. The mortality was 20% in patients with tamponade due to CA/T and 31.6% in patients with VA/T. Pericardiocentesis as first manoeuvre followed by rescue surgical repair was highly effective in case of CA/T (93.8%). At multivariate analysis, CA/T with tamponade was more common in RIATA lead extraction, female patients, leads with a mean dwelling time more than 10 years, and when ≥3 leads were extracted or multiple sheaths required. Occlusion or critical stenosis of superior venous access and the leads mean dwelling time more than 10 years were independent predictors for VA/T, while mechanical dilatation was an independent predictor of a lower incidence of this complication as compared to the use of powered sheaths.Conclusions: In the ELECTRa registry, RIATA lead extraction and superior venous access occlusion/thrombosis are two new independent predictors for cardiac tamponade and major vascular complications, respectively. The use of mechanical sheaths seems to be associated with a lower incidence of VA/T. A strategy of pericardiocentesis followed by a rescue surgical approach seems to be reasonable in order to treat a CA/T with tamponade. [ABSTRACT FROM AUTHOR]

Study Design/setting: Retrospective cohort study., Objective: Assess the extent to which defined risk factors of adverse events are drivers of cost-utility in spinal deformity (ASD) surgery., Methods: ASD patients with 2-year (2Y) data were included. Tertiles were used to define high degrees of frailty, sagittal deformity, blood loss, and surgical time. Cost was calculated using the Pearl Diver registry and cost-utility at 2Y was compared between cohorts based on the number of risk factors present. Statistically significant differences in cost-utility by number of baseline risk factors were determined using ANOVA, followed by a generalized linear model, adjusting for clinical site and surgeon, to assess the effects of increasing risk score on overall cost-utility., Results: By 2 years, 31% experienced a major complication and 23% underwent reoperation. Patients with ≤2 risk factors had significantly less major complications. Patients with 2 risk factors improved the most from baseline to 2Y in ODI. Average cost increased by $8234 per risk factor (R 2 = .981). Cost-per-QALY at 2Y increased by $122,650 per risk factor (R 2 = .794). Adjusted generalized linear model demonstrated a significant trend between increasing risk score and increasing cost-utility (r 2 = .408, P < .001)., Conclusions: The number of defined patient-specific and surgical risk factors, especially those with greater than two, were associated with increased index surgical costs and diminished cost-utility. Efforts to optimize patient physiology and minimize surgical risk would likely reduce healthcare expenditures and improve the overall cost-utility profile for ASD interventions.

Background: Computed tomography (CT)-assessed sarcopenia indexes have been reported to predict postoperative morbidity and mortality; however conclusions drawn from different indexes and studies remain controversial. Aim: The purpose of this meta-analysis was to evaluate various CT-assessed sarcopenia indexes as predictors of risk for major complications in patients undergoing hepatopancreatobiliary surgery for malignancy. Methods: Medline/PubMed, Web of Science, and Embase databases were systematically searched to identify relevant studies published before June 2018. PRISMA guidelines for systematic reviews were followed. The pooled risk ratio (RR) for major postoperative complications (Clavien-Dindo ≥III) was estimated in patients with sarcopenia versus patients without sarcopenia. Data extracted were meta-analyzed using Review Manager (version 5.3). Results: Twenty-eight studies comprising 6,656 patients were included in this study. CT-assessed sarcopenia indexes, such as skeletal muscle index (SMI, RR 1.36; 95% CI 1.14–1.63; p = 0.0008; I2 = 24%), psoas muscle index (PMI, RR 1.35; 95% CI 1.15–1.58; p = 0.0002; I2 = 0%), muscle attenuation (MA, RR 1.40; 95% CI 1.14–1.73; p = 0.002; I2 = 4%), and intramuscular adipose tissue content (IMAC, RR 1.63; 95% CI 1.28–2.09; p < 0.0001; I2 = 0%) were all predictors of postoperative major complications, although moderate heterogeneity existed and cutoffs for these indexes to define sarcopenia varied. Conclusions: All commonly used CT-assessed sarcopenia indexes, such as SMI, PMI, MA, and IMAC can predict the risk of major postoperative complications; however, a consensus on the cutoffs for these indexes to define sarcopenia is still lacking.

Purpose: To analyze major and minor complications following surgery for deeply infiltrating endometriosis including long-term impairment of intestinal, bladder, and sexual function.Methods: Patients who had undergone resection for deeply infiltrating endometriosis without anterior rectal resection between 2001 and 2011 were included (n = 134). Clinical and surgical data, as well as minor and major complications, were recorded. A questionnaire was sent to the patients and to a healthy control group (n = 100).Results: Major complications occurred in 3.7% and minor complications in 12.7% of the patients. Surgical revision was necessary in five cases. The questionnaire response rate was 66.4%, with a mean follow-up period of 75.6 months. Weak urinary flow was reported by 26.4% of the patients; a feeling of residual urine by 16.1%; constipation by 13.5%; more than one bowel movement/day by 16.9%; insufficient lubrication during intercourse by 30.3%. The findings for weak urinary flow, feeling of residual urine, and insufficient lubrication differed significantly from the control group. Subgroup analysis did not identify any statistical associations between questionnaire responses and dyspareunia or dysmenorrhea as reasons for surgery, or previous endometriosis surgery in the patient's history.Conclusions: The major and minor complication rates were consistent with or lower than the literature data. Few studies have investigated complication rates associated with treatment for endometriosis in the sacrouterine ligaments and/or the rectovaginal septum. The high rates of impaired bladder function and sexual function after endometriosis surgery, as well as inadequate data, make further prospective studies on this topic necessary.

Background: There is little population‐level data evaluating risk factors for postoperative complications after total laryngectomy. Methods: We conducted a retrospective review of the American College of Surgeons National Quality Improvement Program identifying patients who underwent total laryngectomy as a primary procedure from 2005 to 2014. Multivariate analysis was performed to identify variables that were independently associated with overall and major complications. Results: Eight hundred seventy‐one cases met inclusion criteria. Three hundred twenty‐eight patients (37.7%) had complications, with operative time (hours; P <.0001), class III (P <.001) wound status, and patient age (decade; P =.003) associated with overall complications. Two hundred one patients had major complications that were associated with steroid use (P =.01) and class III (P =.0083) wound classification. Preoperative hematocrit was correlated with a reduction of all and major complications on multivariate analysis (P <.0001 and P =.036). Conclusion: Identifying and optimizing risk factors may improve outcomes in total laryngectomy. [ABSTRACT FROM AUTHOR]

Introduction: The Revised Trauma Score (RTS) accurately identifies trauma patients at high risk of adverse events or death. Less is known about its usefulness in the general population and non-trauma recipients of Helicopter Emergency Medical Service (HEMS). The RTS is a simple tool and omits a lot of other data obtained during clinical evaluation. The aim was to assess the role of the RTS to identify patients at risk of major complications (death, cardiopulmonary resuscitation, defibrillation, intubation) in the general population of HEMS patients. Clinical factors beyond the RTS were analyzed to identify additional prognostic factors for predicting major complications.Material and Methods: A retrospective analysis of medical records of adult patients routinely collected during HEMS missions in the years 2011-2014 was performed.Results: The analysis included 19 554 HEMS missions. Patients were 55 ±20 years old and 68% were male. The most common indication for HEMS was diseases of the circulatory system - 41%. Major complications occurred in 2072 (10.6%) cases. In the general population of HEMS patients, the RTS accurately identified individuals at risk of major complications at a cut-off value of 10.5 and area under the curve (AUC) of 93.5%. In multivariate analysis, additional clinical data derived from clinical examination (ECG; skin, pupil and breathing examination) significantly but marginally improved the accuracy of RTS assessment: AUC 95.6% (p < 0.001 for the difference).Conclusions: The Revised Trauma Score accurately identifies individuals at risk of major complications during HEMS missions regardless of the indication. Additional clinical data significantly but marginally improved the accuracy of RTS in the general population of HEMS patients. [ABSTRACT FROM AUTHOR]

Background Context: Several studies have suggested that laboratory results have minimal impact on clinical decision making in surgery. Despite the widespread use of preoperative testing in spine surgery and the large volume of posterolateral lumbar fusions (PLFs) being performed each year, no study has assessed the ability of preoperative laboratories to predict adverse events following PLF.Purpose: The purpose of this study was to explore the relationship between commonly obtained preoperative laboratory results and postoperative complications following one- to two-level PLF.Study Design: This is a retrospective study of prospectively collected data.Patient Sample: The 2006-2013 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was employed to identify all patients who underwent one- to two-level PLF.Outcome Measures: The outcome variables of interest were 30-day postoperative complications, which were assessed as major complications, minor adverse events, and total complications.Materials and Methods: Demographics, comorbidities, and perioperative characteristics were collected for each patient. Preoperative laboratories included sodium, blood urea nitrogen, creatinine, albumin, bilirubin, serum glutamic oxaloacetic transaminase, alkaline phosphatase, white blood cell count, hematocrit, platelet count, prothrombin time, international normalized ratio, and partial thromboplastin time. Bivariate analysis and multivariate logistic regression modeling were used to explore the relationship between abnormal preoperative laboratories and the incidence of postoperative complications.Results: After controlling for age, ASA score, length of surgery, and all significant comorbidities, abnormal sodium (odds ratio [OR]=2.47, 95% confidence interval [CI]: 1.45-4.19, p=.001) and abnormal INR (OR=2.33, 95% CI: 1.09-4.98, p=.029) were significantly associated with the development of any complication. Sodium (OR=1.61, 95% CI: 1.01-2.54, p=.04) and platelets (OR=1.58, 95% CI: 1.02-2.44, p=.04) were associated with minor complications. Meanwhile, creatinine (OR=1.74, 95% CI: 1.02-2.99, p=.04) and platelets (OR=1.71, 95% CI: 1.02-2.89, p=.04) were significant predictors of major adverse events.Conclusions: This study represents the first attempt to assess the utility of preoperative laboratories in predicting postoperative complications in PLF. Although the majority of laboratories were not significantly associated with adverse events, abnormal sodium values, INR, creatinine, and platelets were shown to be predictive of various complications.

Purpose: The aim of the present study was to analyze major and minor complications-including long-term impairment of intestinal, bladder, and sexual function-following surgery for deeply infiltrating endometriosis using anterior rectal resection.Methods: Patients who had undergone anterior rectal resection due to endometriosis between 2001 and 2011 were included (n = 113). Clinical and surgical data, as well as minor and major complications, were recorded. A questionnaire was sent to the patients and also to a healthy control group (n = 100).Results: Major complications occurred in 15.9% of cases and minor complications in 15%. Patients with postoperative ileostomies (n = 8) initially had ultralow anastomoses significantly more often. The questionnaire response rate was 77%, with a mean follow-up period of 85.9 months. Weak urinary flow was reported by 22.4% of the patients: a feeling of residual urine by 18.4%; more than one bowel movement/day by 57.5%; and insufficient lubrication during intercourse by 36.5%. These results differed significantly from the control group. Subgroup analysis showed no statistical associations between questionnaire responses and major or minor complications, ultralow anastomoses, bilateral dissection of the sacrouterine ligaments, or dissection of the vagina and rectovaginal space.Conclusions: The major complication rate was consistent with the literature, but there were fewer minor complications. Patients with bowel anastomoses below 6 cm (ultralow) should receive information postoperatively about the high risk of insufficiency and should be closely monitored. The high rate of bladder, bowel, and sexual function impairment, and inadequate data make further prospective studies on this topic necessary. [ABSTRACT FROM AUTHOR]
