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]

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: 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.

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]

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 < 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]

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]

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 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]

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.

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.

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.

Quality indicators are by definition indirect measures of quality. The selection for the field of pancreatic surgery was based on the clinical relevance and controllability, scientific evidence and the practicability of data acquisition. In terms of outcome quality, hospital mortality, the composite endpoint MTL30 (mortality-transfer-length of stay), and major complications (Clavien-Dindo classification grades 3b and 4) were chosen as being essential. With respect to structural quality, the presence of interventional radiology with constant availability was considered essential. To evaluate target values two strategies were used: a systematic literature search and evaluation of the current numbers from the German Society for General and Visceral Surgery (DGAV) StuDoQ|Pancreas registry for the years 2014-2016. The results are presented in the following consensus statement. [ABSTRACT FROM AUTHOR]

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]

Background: Older patients are increasingly faced with pancreatic surgery because of shifting demographics. The differential effects of aging on surgical outcomes remain vague, while the elderly patient is often neglected in clinical trials. Methods: Medical records of 370 patients who underwent pancreaticoduodenectomy were analyzed. Patients were then subdivided into 3 groups according to age and comorbidities. Results: Overall mortality was 5% and did not significantly differ between age-matched groups. Increasing age was linked to a higher prevalence of diabetes mellitus (p < 0.001) and preoperative cardiovascular comorbidities (p < 0.001). Independent risk factors for major complications were age over 70 years (p = 0.018; OR 2.3), elevated body mass index (p = 0.004; OR 0.2) and cardiovascular comorbidities (p = 0.022; OR = 2.6). Patients who were older (>70 years), obese and had cardiovascular disease had an increased risk of major complications when compared with the younger study population (p = 0.010). Conclusions: Pancreatic surgery in elderly patients showed similar mortality rates as in younger patients. Nevertheless, a careful risk assessment is particularly important because older patients who are considered to be high risk suffer more frequently from major surgical complications compared with young patients that have similar risk profiles.

Study Design: A multicenter, prospective, consecutive database of surgical patients with adult spinal deformity (ASD).Objective: This study investigated the use of antifibrinolytic (AF) therapy in ASD surgery.Summary Of Background Data: AF therapy has been shown to be effective in preventing blood loss in some settings. Its effect on major and minor perioperative complications, blood product utilization, vascular events, and postoperative fusion in patients undergoing ASD surgery remains unclear.Methods: All patients with data on AF use were included. Parameters of blood utilization included transfusion rates and units of packed red blood cells and fresh frozen plasma transfused. Thromboembolic events included stroke, deep vein thrombosis, and pulmonary embolus. Multivariate regression was used, accounting for confounders.Results: Four hundred three patients were included. One hundred thirty-seven patients received aminocaproic acid (EACA), 81 received tranexamic acid (TXA), and 185 received no AFs. The use of AF was associated with a decrease in transfusion (EACA: odds ratio [OR] = 0.38, P = 0.043; TXA: OR = 0.31, P = 0.047), a decrease in the number of units of packed red blood cells transfused (EACA: incidence risk ratio [IRR] = 0.45, P = 0.0005; TXA: IRR = 0.7, P = 0.0005), and a decrease in the number of fresh frozen plasma transfused (EACA: IRR = 0.65, P = 0.003; TXA: IRR = 0.67, P = 0.006). AF use was associated with an increase in minor intraoperative complications (EACA: IRR = 2.15, P = 0.008; TXA: IRR = 2.12, P = 0.011). TXA use (but not EACA) was associated with a decrease in the incidence of major perioperative complications compared with no AF (IRR = 0.37, P = 0.019). There was no difference in the incidence of thromboembolic events.Conclusion: TXA or EACA use was associated with increased minor intraoperative complications. TXA was associated with decreased major perioperative complications. AF was associated with decreased utilization of blood products without an increased rate of thromboembolic events. Given the nature of this study, transfusion threshold was not standardized. Future studies with rigid criteria for transfusion should be prospectively performed to better evaluate the impact of AF during ASD surgery.Level Of Evidence: 3. [ABSTRACT FROM AUTHOR]

Objectives: This study aims to evaluate the role of dynamic change in total bilirubin after portal vein embolization (PVE) in predicting major complications and 30-day mortality in patients with hilar cholangiocarcinoma (HCCA).Methods: Retrospective analysis of prospectively maintained data of 64 HCCA patients who underwent PVE before hepatectomy in our institution was used. Total bilirubin and other parameters were measured daily in peri-PVE period. The difference between them and the baseline value from days 0-5 to day -1 (∆D1) and days 5-14 to day -1 (∆D2) were calculated. The relationship between ∆D1 and ∆D2 of total bilirubin and major complications as well as 30-day mortality was analyzed.Results: Out of 64 patients, 10 developed major complications (15.6 %) and 6 patients (9.3 %) had died within 30 days after surgery. The ∆D2 of total bilirubin after PVE was most significantly associated with major complications (P < 0.001) and 30-day mortality (P = 0.002). In addition, it was found to be an independent predictor of major complications after PVE (odds ratio (OR) = 1.050; 95 % CI 1.017-1.084). ASA >3 (OR = 12.048; 95 % CI 1.019-143.321), ∆D2 of total bilirubin (OR = 1.058; 95 % CI 1.007-1.112), and ∆D2 of prealbumin (OR = 0.975; 95 % CI 0.952-0.999) were associated with higher risk of 30-day mortality after PVE. Receiver operating characteristic curves showed that ∆D2 of total bilirubin were better predictors than ∆D1 for major complications (AUC (∆D2) 0.817; P = 0.002 vs. AUC (∆D1) 0.769; P = 0.007) and 30-day mortality (ACU(∆D2) 0.868; P = 0.003 vs. AUC(∆D1) 0.721;P = 0.076).Conclusion: Patients with increased total bilirubin in 5-14 days after PVE may indicate a higher risk of major complications and 30-day mortality if the major hepatectomy were performed.

Background: Laparoscopic spleen-preserving total gastrectomy (LSPTG) for gastric cancer is only performed at a few specialized institutions and carries the risk of major perioperative complications (MPCs) that may require reoperation and impair recovery. However, the predictors of such events remain largely unknown.Methods: Prospectively collected data from 325 consecutive patients undergoing LSPTG at a single institution from June 2011 to February 2014 were analyzed to determine the preoperative factors that correlated with MPCs. The rates of MPCs were assessed, and a score model was developed to identify preoperative variables associated with MPC.Results: Of the 325 LSPTG cases, the following types of MPCs were observed in 15 (4.6%) patients: intraoperative splenic hilar vascular injury (n = 1); intraoperative splenic parenchymal injury (n = 5); intraoperative splenic infarction (n = 1); intraabdominal abscess that required radiological intervention [not under general anesthesia (n = 2)]; intra-abdominal bleeding that required reoperation under general anesthesia (n = 2); anastomotic hemorrhage that required reoperation under general anesthesia (n = 2); and death (n = 2). Three independent variables were correlated with MPCs in the multivariate analysis: body mass index (BMI) ≥25 kg/m(2) (odds ratio [OR] 3.992, 95% confidence interval [CI] 1.210-13.175), tumor located at the greater curvature (OR 3.922, 95% CI 1.194-12.880), and No.10 LN metastases (OR 4.418, 95 % CI 1.250-13.770). A risk score consisting of one point for each preoperative risk factor (BMI ≥ 25 kg/m(2) or tumor location in the greater curvature), resulting in an overall score of 0-2 points for each patient, predicted an increased risk of MPCs.Conclusions: BMI, tumor location, and No.10 LN metastases were significantly associated with increased rates of MPCs. A simple, clinically relevant scoring system based on two preoperative variables was clinically useful in predicting MPC risk in patients undergoing LSPTG. [ABSTRACT FROM AUTHOR]

The article discusses a study which determined the prevalence of major complications in revision adult spinal deformity surgery. Out of 166 patients, 107 are diagnosed with idiopathic/de novo scoliosis, 35 with degenerative, 7 with trauma, 6 with neuromuscular scoliosis, 5 with congenital deformity, 2 with ankylosing spondylitis, and 2 with tumor. Equivalent outcome scores were reported by patients, but those experiencing complications reported lower scores at final follow-up.

Total thyroidectomy (TT) in patients with Graves' disease is challenging even for an experienced thyroid surgeon. This study aimed to investigate the accumulation of experience and applying newly developed devices on major complications and voice outcomes after surgery of a single surgeon over 30 years. This study retrospectively reviewed 90 patients with Graves' disease who received TT. Forty-six patients received surgery during 1990–1999 (Group A), and 44 patients received surgery during 2010–2019 (Group B). Major complications rates were compared between Group A/B, and objective voice parameters were compared between the usage of energy-based devices (EBDs) within Group B. Compared to Group B, Group A patients had higher rates of recurrent laryngeal nerve palsy (13.0%/1.1%, p = 0.001), postoperative hypocalcemia (47.8%/18.2%, p = 0.002), and postoperative hematoma (10.9%/2.3%, p = 0.108). Additionally, Group A had one permanent vocal cord palsy, four permanent hypocalcemia, and one thyroid storm, whereas none of Group B had these complications. Group B patients with EBDs had a significantly better pitch range (p = 0.015) and jitter (p = 0.035) than those without EBDs. To reduce the major complications rate, inexperienced thyroid surgeons should remain vigilant when performing TT for Graves' disease. Updates on surgical concepts and the effective use of operative adjuncts are necessary to improve patient safety and voice outcome. [ABSTRACT FROM AUTHOR]

Simple Summary: Skeletal muscle mass (SMM) depletion is gaining popularity as independent predictor of postoperative complications in many surgical scenarios, even in the field of head and neck oncology. In this study, we demonstrate the value of ultrasound scans of the rectus femoris muscle together with the neck CT/MRI at C3 level in terms of estimation of SMM (through muscle cross sectional area), the identification of sarcopenic patients and as a predictor of major surgical morbidity in a cohort of locally-advanced head and neck cancer patients submitted to surgical treatment. This provides important tools for the on-going re-assessment of patients with regards to any pre-habilitation strategy aimed at reducing postoperative complications. Skeletal muscle mass (SMM) depletion has been validated in many surgical fields as independent predictor of complications through cross-sectional imaging. We evaluated SMM depletion in a stage III-IV head and neck cancer cohort, comparing the accuracy of CT/MRI at C3 level with ultrasound (US) of rectus femoris muscle (RF) in terms of prediction of major complications. Patients submitted to surgery were recruited from 2016 to 2021. SMM was estimated on CT/MRI by calculating the sum of the cross-sectional area (CSA) of the sternocleidomastoid and paravertebral muscles at C3 level and its height-indexed value (cervical skeletal muscle index, CSMI) and on US by computing the CSA of RF. Specific thresholds were defined for both US and CT/MRI according to ROC curve in terms of best prediction of 30-day major complications to detect sarcopenic subjects (40–53%). Sixty-five patients completed the study. At univariate analysis, major complications were associated to lower RF CSA, lower CSA at C3 level and lower CSMI, together with previous radiotherapy, higher ASA score and higher modified frailty index (mFI). At multivariate analysis RF CSA (OR 7.07, p = 0.004), CSA at C3 level (OR 6.74, p = 0.005) and CSMI (OR 4.02, p = 0.025) were confirmed as independent predictors in three different models including radiotherapy, ASA score and mFI. This analysis proved the value of SMM depletion as predictor of major complications in a head and neck cancer cohort, either defined on cross-sectional imaging at C3 or on US of RF.

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. [ABSTRACT FROM AUTHOR]

The article focuses on the short-term complications arising after the treatment of localized prostate cancer using radiotherapy (RT). This treatment is commonly used for older men and men with comorbid illnesses. The rates of major short-term complications leading to hospitalization after RT have been reported by population-based studies. The reports suggest that post RT, such complications were relatively uncommon, generally increased with an increase in patient age and declined over time.

Learning Objectives: To describe normal anatomy of Roux-en-Y gastric bypass (GBP) surgery. To know the spectrum of major complications, time of appearance and imaging findings. Background: Roux-en-Y GBP surgery nowadays represents a successful treatment of morbid obesity. From January 1999 to June 2005, 148 patients with Roux-en-Y GBP surgery have been reviewed. Within a period of 24-72 h after surgery, upper gastrointestinal series was performed. The radiographic manifestations of normal anatomy and follow-up major complications are illustrated in this pictorial essay. We compare the CT and other imaging findings with clinical and surgical findings. Imaging Findings: A total of 14 follow-up major complications occurred in 9 of 148 patients. Only 3 were early complications, the other 11 were late and appeared between 1 month and 4 years. Imaging findings of stomal stenosis, gastric staple line dehiscence, leaks, jejunal and gastric wall necrosis, small bowel obstruction due to adhesions, loculated fluid collection and celiac trunk stenosis are illustrated. Conclusion: It is important for the radiologist to be familiarized with the radiographic manifestations of normal anatomy and major complications after Roux-en-Y GBP. These may be life-threatening and usually appear as late complications. An adequate imaging technique and a prompt evaluation by the radiologist can help to minimize them. [ABSTRACT FROM AUTHOR]

Study Objective: The potential of perioperative goal-directed therapy (PGDT) to improve outcome after high-risk abdominal surgery remains subject of debate. In particular, there is a need for large, multicenter trials focusing on relevant patient outcomes to confirm the evidence found in small, single center studies including minor complications in their composite endpoints. The present study therefore aims to investigate the effect of an arterial waveform analysis based PGDT algorithm on the incidence of major complications including mortality after high-risk abdominal surgery.Design: Prospective randomized controlled multicenter trial.Setting: Operating theatres and Post-Anesthesia/Intensive Care units (PACU/ICU) of four tertiary hospitals in The Netherlands.Patients: A total number of 482 patients undergoing elective, abdominal surgery that is considered high-risk due to the extent of the procedure and/or patient comorbidities.Interventions: Hemodynamic therapy using an age-specific PGDT algorithm including cardiac index (CI) and stroke volume variation (SVV) measurements during a 24-h perioperative period starting at induction of anesthesia.Measurements: The average number of major complications (including mortality) within 30 days after surgery, the number of minor complications, hospital and PACU/ICU length of stay (LOS), amounts of fluids and vasoactive medications used. Complications were graded using the Accordion severity grading system.Results: The average number of major complications per patient was 0.79 (PGDT group) versus 0.69 (control group) (p = 0.195). There were no statistically significant differences in the number of minor complications, hospital LOS, PACU/ICU LOS, or grading of complications. Patients in the PGDT group received more fluids intraoperatively, more dobutamine intra- and postoperatively, while patients in the control group received more phenylephrine during the operation.Conclusions: PGDT based on a CI and SVV driven algorithm did not result in improved outcomes after high-risk abdominal surgery.Clinical Trial Registration: Netherlands Trial Registry: NTR3380.

The diagnosis of ankyloglossia, or tongue-tie, and the number of frenotomies performed has increased over 10-fold from 1997 to 2012 in the United States. The sharpest increase has been in neonates. For parents considering frenotomy for their breastfeeding newborn, there is controversy surrounding the evaluation of tongue-tie and the benefit of a frenotomy. Complications from tongue-tie procedures are thought to be low, though it is not well reported nor studied. The aim of this study is to describe a case of a sublingual mucocele after laser frenotomy in a neonate with tongue-tie and to investigate major complications reported after tongue-tie release in pediatric patients through a systematic review of the literature. We present a 6-week-old female who underwent a laser frenotomy procedure performed by a dentist who presented with a new cyst under her tongue. A systematic literature search of articles published from 1965 to April 2020 was conducted in Ovid MEDLINE(R), Ovid EMBASE, and Scopus. Citations were uploaded into a systematic review software program (DistillerSR, Ottawa, ON, Canada), followed by full text screening. 47 major complications were reported in 34 patients, including our patient. Most of the cases were located in the United States and Europe. The most frequent indications for the procedure were breastfeeding problems (n = 18) and speech impediment (n = 4). The procedure was performed by dentists (n = 6), lactation consultants (n = 5), and otolaryngologists (n = 4). The bulk of the major complications after frenotomy included poor feeding (n = 7), hypovolemic shock (n = 4), apnea (n = 4), acute airway obstruction (n = 4), and Ludwig angina (n = 2). Reporting of complications after frenotomy is lacking. Risks to neonates may be different than risks to older children and adults. Practitioners across different specialties should be monitoring and studying this more rigorously to better guide patients and families on the risks and benefits of this procedure.

This prospective observational study aimed to assess the feasibility of adapting peritoneal hyperdistention to 25 mmHg during laparoscopy in an Australian hospital environment. A total of 1150 consecutive diagnostic or operative laparoscopies were performed. All cases were monitored for early detection of untoward physiological changes. All patients had Veress needle insufflation with distension to 25 mmHg prior to insertion of the primary trocar. No patients experienced any surgical entry complications or adverse clinical effects noted during anaesthetic. The aim of the current study is to assess the feasibility and safety of increasing the peritoneal insufflation pressure to 25 mmHg for primary trocar insertion. [ABSTRACT FROM AUTHOR]
