Risk Of Overall Complications Research Articles

The Effectiveness and Safety of Leadless Pacemakers: An Updated Meta-Analysis.

Leadless pacemakers (LPs) are promising alternatives to traditional transvenous pacemakers (TVPs), but their comparative effectiveness and safety in clinical outcomes remain uncertain. We systematically searched PubMed, Embase, Scopus, Cochrane, and ClinicalTrials.gov for studies comparing LPs and TVPs. A restricted maximum likelihood random-effects model was used for all outcomes. Heterogeneity was assessed using I2 statistics. We performed a subgroup analysis with studies with multivariate-adjusted data. We included 21 studies involving 47,229 patients, of whom 12,199 (25.8%) underwent LP implantation. Compared with TVPs, LPs were associated with a significantly lower risk of overall complications (OR 0.61; 95% CI 0.45-0.81; p < 0.01), dislodgement (OR 0.34; 95% CI 0.20-0.56; p < 0.01), and pneumothorax (OR 0.27; 95% CI 0.16-0.46; p < 0.01). No significant difference in all-cause mortality was observed in the overall analysis (OR 1.43; 95% CI 0.65-3.15; p = 0.35) and in studies with multivariate-adjusted data (OR 1.34; 95% CI 0.65-2.78; p = 0.43). However, LPs were associated with a higher risk of pericardial effusion (OR 2.47; 95% CI 1.39-4.38; p < 0.01) and cardiac tamponade (OR 3.75; 95% CI 2.41-5.83; p < 0.01). LPs also demonstrated a lower pacing capture threshold (MD -0.19V; 95% CI [-0.23V]-[-0.16V]; p < 0.01), but no significant difference in impedance (MD 32.63 ohms; 95% CI [-22.50 ohms]-[87.76 ohms]; p = 0.25). These findings suggest that LPs were associated with lower overall complication rates and similar effectiveness to TVPs. However, randomized controlled trials are warranted to validate these results.

The impact of previous abdominal surgery on colorectal cancer patients undergoing laparoscopic surgery.

The current study aimed to investigate whether previous abdominal surgery (PAS) could affect the outcomes of colorectal cancer (CRC) surgery. We conducted the search strategy in three databases (PubMed, Embase, and the Cochrane Library) from inception to May 26, 2022. The short-term and long-term outcomes were compared between the PAS group and the non-PAS group. Odds ratios (ORs) and 95% confidence intervals (CIs) were pooled up. Stata (V.16.0) software was used for data analysis. We included 34,827 patients from 14 studies in the current study. After pooling up all the data, we found that there were higher proportions of overall complications (OR = 1.12, I2 = 4.65%, 95% CI 1.03 to 1.23, P = 0.01), ileus (OR = 1.96, I2 = 59.74%, 95% CI 1.12 to 3.44, P = 0.02) and mortality (OR = 1.26, I2 = 0.00%, 95% CI 1.11 to 1.42, P = 0.00) in the PAS group than the non-PAS group. Patients with a history of PAS had higher risks of overall complications and death following CRC surgery. However, it did not appear to significantly affect the short-term outcomes apart from ileus. Surgeons should raise awareness of patients with a history of PAS, and take steps to reduce postoperative complications and mortality.

The effect of omentoplasty in various surgical operations: Systematic review and meta-analysis.

Omentoplasty is commonly used in various surgeries. However, its effectiveness is unsure due to lack of convincing data and research. To clarify the impact of omentoplasty on postoperative complications of various procedures, this systematic review and meta-analysis was performed. A systematic review of published literatures from four databases: PubMed, Web of Science, Cochrane Library, and Embase before July 14, 2022. We primarily included publications on five major surgical operations performed in conjunction with omentoplasty: thoracic surgery, esophageal surgery, gastrointestinal surgery, pelvi-perineal surgery, and liver surgery. The protocol was registered in PROSPERO. This review included 25 273 patients from 91 studies (n=9 670 underwent omentoplasty). Omentoplasty was associated with a lower risk of overall complications particularly in gastrointestinal (RR 0.53; 95%CI 0.39-0.72) and liver surgery (RR 0.54; 95%CI 0.39-0.74). Omentoplasty reduced the risk of postoperative infection in thoracic (RR 0.38; 95%CI 0.18-0.78) and liver surgery (RR 0.39; 95%CI 0.29-0.52). In patients undergoing esophageal (RR 0.89; 95%CI 0.80-0.99) and gastrointestinal (RR 0.28; 95%CI 0.23-0.34) surgery with a BMI greater than 25, omentoplasty is significantly associated with a reduced risk of overall complications compared to patients with normal BMI. No significant differences were found in pelvi-perineal surgery, except infection in patients whose BMI ranged from 25kg/m2 to 29.9kg/m2 (RR 1.25; 95%CI 1.04-1.50) and anastomotic leakage in patients aged over 60 (RR 0.59; 95%CI-0.39-0.91). Omentoplasty can effectively prevent postoperative infection. It is associated with a lower incidence of multiple postoperative complications in gastrointestinal and liver surgery.

Postoperative morbidity following Hartmann's procedure in comparison to anterior resection and abdominoperineal resection for rectal cancer-a population-based study.

There is ongoing controversy regarding the extent to which Hartmann's procedure (HP) should be used in rectal cancer treatment. This study was designed to investigate 30-day postoperative morbidity and mortality following HP, anterior resection (AR) and abdominoperineal resection (APR) for rectal cancer using a national registry. All patients operated for rectal cancer, tumour height 5-15 cm, between the years 2010 and 2017, were identified through the Swedish colorectal cancer registry. A total of 8476 patients were included: 1210 (14%) undergoing HP, 5406 (64%) AR and 1860 (22%) APR. HP was associated with an increased risk of intra-abdominal infection (OR 1.7, CI 1.26-2.28, P = 0.0004) compared to AR and APR, while APR was related to an increased risk of overall complications (OR 1.18, CI 1.01-1.40, P = 0.040). No significant difference was observed in the rate of reoperations and readmissions between HP, AR and APR, and type of surgical procedure was not a risk factor for 30-day mortality. Findings from a subgroup analysis of patients with a tumour 5-7 cm from the anal verge revealed that HP was not associated with increased risk for complications or 30-day mortality. For patients where AR is not appropriate HP is a valid alternative with a favourable outcome. APR was associated with the highest overall 30-day complication rate.

Smoking impacts outcomes in transcervical Zenker's diverticulectomy

PurposeThere is sparse literature discussing the impact of smoking on postoperative outcomes following surgical treatment of Zenker's diverticulum. In this study, we seek to characterize differences in the management and outcomes of open Zenker's diverticulectomy based on patient smoking status. Methods and materialsThis paper is a retrospective cohort review. The 2005–2018 American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database was queried for patients undergoing open Zenker's diverticulectomy. Chi-square and multivariable logistic regression were performed to determine statistical associations between postoperative outcomes and smoking status. ResultsOf the 715 identified patients, 70 (9.8 %) were smokers and 645 (91.2 %) were non-smokers. Smokers were younger than non-smokers (mean 63.9 vs. 71.7 years, p < 0.001) and more likely to have a prolonged operative time (20.0 % vs. 11.6 %, p = 0.044). On multivariable regression analysis controlling for demographics and comorbidities, smokers had greater odds than non-smokers for developing overall postoperative complications (OR: 2.776, p = 0.013), surgical infections (OR: 3.194, p = 0.039), medical complications (OR: 3.563, p = 0.011), and medical infections (OR: 1.247, p = 0.016). Smokers also had greater odds for requiring ventilation/intubation (OR: 8.508, p = 0.025) and having a prolonged postoperative stay (OR: 2.425, p = 0.030). ConclusionIn a cohort of patients undergoing transcervical Zenker's diverticulectomy, smokers are at increased risk for overall complications, medical complications, medical infections, surgical infections, prolonged postoperative stay, and ventilation/intubation.

Risk of complications and implant survival of surgical treatment of proximal femoral metastasis: a meta-analysis.

The patients with femoral metastasis in the inter- or subtrochanteric area could be treated with intramedullary nailing or prosthetic reconstruction, however, it is controversial which surgical treatment could offer less complications and implant failure. Our purpose was to define the risk of complications and implant survival in patients treated with intramedullary nailing or prosthetic reconstruction. We analyzed studies reporting the risk of complications, reoperations and removal of the implant in patients treated with intramedullary nailing, hemiarthroplasty, arthroplasty or megaprosthesis. We analyzed 27 studies (1346 patients) reporting patients treated with intramedullary nail (51%), hemiarthroplasty (15%), arthroplasty (2%), megaprosthesis with (25%) or without (7%) acetabular component. No difference was found in the overall risk of complications between patients treated with intramedullary nailing 6%, hemiarthroplasty or total hip arthroplasty 7% and megaprosthesis 11% (p = 0.23). However, patients treated with megaprosthesis had increased risk of reoperation due to infection (70%), compared to the patients treated with intramedullary nail (13%), and patients treated with hemiarthroplasty or total hip arthroplasty (23%) (p = 0.02). Revision due to disease progression was required in 61% of the patients treated with intramedullary nail, but not in patients treated with hemiarthroplasty, total arthroplasty, and megaprosthesis (p = 0.03). Patients treated with megaprosthesis had higher risk of reoperation due to infection, while patients treated with intramedullary nailing had higher risk of revision due to disease progression. Regarding patients treated with megaprosthesis, the risk of reoperation due to dislocation was higher in those treated with acetabular component.

Twelve Years and over 2400 Implants Later: Augmentation Mammoplasty Risk Factors Based on a Single Plastic Surgeon’s Experience

Background: Breast augmentation is one of the most commonly performed aesthetic surgery procedures. Yet, few reports in the literature analyze individual surgeon experiences with a unified surgical method on a large group of patients. This study aimed to analyze a single surgeon’s complications rate and experience with the Akademikliniken augmentation mammaplasty method from the beginning of his career. Methods: A retrospective outcome analysis of all patients (n = 1646) who underwent breast augmentation between 2009 and 2021 performed by a single surgeon was conducted. Complications and reoperation rates were evaluated. In addition, correlations with the patient and implant characteristics and insertion-method–related risk factors were analyzed. Results: In total, 1212 female patients (mean age, 31.47 years) were analyzed. The minimal follow-up for every patient was 6 months (mean follow-up, 18.35 months). The total complication rate was 7.1%, and the most common complication (2.64%) was capsular contracture (Baker scale III/IV). Implant insertion with a funnel significantly lowered the overall risk of complications (P = 0.009). Statistical analysis indicates that the single independent risk factors for primary breast augmentation are patient age younger than 27 years, initial breast size B and C, and tobacco smoking. Conclusions: This study indicated that capsular contracture and implant rotation are the most common complications of analyzed primary augmentation mammoplasty. It also identifies various risk and protection factors, such as funnel usage, which should be considered by the surgeon when performing this type of procedure.

Should Chronological Age be a Consideration in Patients Undergoing Elective Primary Total Knee Arthroplasty?

BackgroundThe optimal time for total knee arthroplasty (TKA) requires a balance between patient disability and health state to minimize complications. While chronological age has not been shown to be predictive of complications in elective surgical patients, there is a point beyond which even optimized elderly patients would be at increased risk for complications. The purpose of this study was to examine the impact of chronological age on complications following primary TKA. MethodsUsing an administrative database, the records of 2,129,191 patients undergoing elective unilateral TKA between 2006 and 2021 were reviewed. The primary outcomes of interest were cardiac and pulmonary complications, and their relationship to the Charlson-Deyo Comorbidity Index (CDI) and chronological age. Secondary outcomes included risk of renal, neurologic, infection, and intensive care utilization postoperatively. The results were analyzed using a graphical method. The impact of chronological age as a modifier of overall risk for complications was modeled as a continuous variable. An age cutoff threshold of 80 years was also assigned for clinical convenience. ResultsThe risk of complications correlated more closely to the CDI (odds ratio (OR) 1.37 to 2.1) than chronological age (OR 1.0 to 1.1) across the various complications [Table 1. However, beyond age 80 years, the risks of cardiac, pulmonary, renal, and cerebrovascular complications were significantly increased for all CDI categories (OR 1.73 to 3.40) compared to patients below age 80 years [Table 2] [Figures 1A and 1B]. ConclusionsChronologic age can impact the risk of complications even in well-optimized elderly patients undergoing primary TKA. As arthroplasty continues to transition to outpatient settings and inpatient denials increase, these results can help patients, physicians, and payors mitigate risk while optimizing the allocation of resources.

Comparison of Outcomes in Below-Knee Amputation Based on Surgeon Specialty

Introduction/Purpose: Orthopaedic, vascular, and general surgeons all perform lower extremity amputations. Previous studies have indicated that outcomes may be related surgeon experience or skill, with a similar study indicating that general surgeons experience worst postoperative outcomes than vascular surgeons. In spite of these studies, there is a paucity of literature investigating the difference in outcomes between amputations performed by orthopaedic and vascular surgeons. This study aims to analyze the effect of surgeon specialty on 30-day complication, readmission, reoperation, and mortality rates following below-knee amputation (BKA) procedures between orthopaedic and vascular surgeons. Methods: The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database was queried from 2010-2019 to identify 28,776 patients undergoing BKA by either orthopaedic, general, or vascular surgeons using Current Procedural Terminology (CPT) codes 27880, 27881, and 27882. Patients were stratified into groups based on surgeon specialty with 18,935 (66.4%) cases performed by vascular surgeons, 6,146 (21.6%) cases by general surgeons, and 3,429 (15.3%) cases were performed by orthopaedic surgeons. Demographics, comorbid conditions, hospital length of stay (LOS), and 30-day complications, readmission, reoperation, and mortality rates were compared between groups. Univariate and multivariate analysis were performed to examine the associations between outcomes and surgical specialty, while controlling for comorbid conditions as measured by ASA score and 5-factor modified frailty index (mFI-5) score. Results: The cohort was predominantly male (68.4%), white (61.9%), and the mean age was 63.54 (range, 18-90) years. The cohort of patients treated by vascular and general surgeons had significantly higher rates of numerous comorbidities, including mFI-5 score (p &lt;.001) and ASA score (p &lt;.001). When controlling for age, gender, BMI, and comorbid conditions, BKAs performed by vascular and general surgeons experienced an increased risk overall complication (General: Odds ratio [OR]=1.158, 95% confidence Interval [CI]=1.055-1.271; p=.002) (Vascular: OR=1.167, 95%CI=1.074-1.268; p&lt;.001), readmission (General: OR=1.208; p=.011) (Vascular: OR=1.191; p=.009), and reoperation (General: OR=1.71;, p&lt;.001) (Vascular: OR=1.975; p&lt;.001). However, both general (OR=0.361, 95%CI=0.27-0.482; p&lt;.001) and vascular surgeons (OR=0.367, 95%CI= 0.256-0.526; p&lt;.001) surgeons experience decreased risk for organ/space SSI as compared to orthopaedic surgeons. Overall risk of mortality between specialties was not significantly different. Conclusion: There was no significant difference in rates of overall 30-day mortality in patients undergoing between surgical specialties when employing multivariate controls. However, patients undergoing BKA by vascular or general surgeons were found to have an increased risk of overall complication, readmission, and reoperation.

Comparison of percutaneous decannulation and open surgical repair for large-bore arterial access sites of extracorporeal membrane oxygenation.

Following weaning of peripheral venoarterial extracorporeal membrane oxygenation (ECMO) support, removal of cannulas and repair of large-bore arterial sites is traditionally by open surgical repair (OSR). The use of a percutaneous vascular closure device (VCD) offers a minimally invasive alternative to OSR with potential for reduced operative complications, reduced hospital length of stay and in-hospital mortality. A systematic review of Medline and Embase databases was conducted for studies comparing VCD-assisted decannulation with OSR following decannulation of peripheral ECMO. The primary endpoint was rate of post-procedural complications, namely wound infection and limb ischaemia. The secondary endpoint was in-hospital mortality. Eight studies, with a total of 685 patients, met inclusion criteria. Forty-eight percent (n = 328) of patients underwent VCD-assisted decannulation with the remainder decannulated by OSR. Pooled analysis demonstrated that patients undergoing VCD-assisted decannulation are at significantly lower risk of overall complications than surgical repair (OR 4.34; 95% CI 2.19-8.57; p < .001). Specifically, there was a substantial decrease in groin infections (OR 6.77; 95% CI 3.07-14.97; p < .001) without notable differences in limb ischaemia or pseudoaneurysm occurrence between the VCD and OSR cohorts. There was a lower incidence of intra-operative bleeding and haematoma in the VCD cohort (p < .001 and p = .002, respectively). Vascular closure device-assisted decannulation of peripheral ECMO offers a significantly reduced risk of complications, particularly groin infections and bleeding. Future research should encompass larger cohorts, randomised controlled trials, cost-benefit analyses, and the training of surgeons, cardiologists and intensivists in VCD-assisted decannulation, potentially through the integration of simulation-based training.

Evaluation of Outcomes Between the Top-down Versus the Bottom-up Approach for Retropubic Midurethral Sling

Introduction and hypothesisRetropubic midurethral sling (MUS) placement is the gold standard for the treatment of stress urinary incontinence in the USA. The procedure can be approached from either a top-down or a bottom-up direction, but there is a paucity of contemporary data regarding outcomes between these approaches. The aim of this study was to provide updated clinical outcomes data.MethodsThis was a retrospective cohort study of women undergoing the retropubic MUS procedure alone or at the time of pelvic organ prolapse repair between 2010 and 2020 at a single academic medical center. The electronic medical record was used to extract demographic data, operative approach, and perioperative complications. The primary outcome was a composite incidence of any perioperative complication.ResultsOf the 309 patients analyzed, 140 (45.3%) underwent top-down and 169 (54.7%) underwent bottom-up retropubic MUS placement. Patients undergoing top-down MUS placement were more likely to be older (mean age 58 vs 54, p=0.02), have a history of diabetes mellitus (20% vs 8.9%, p=0.004), and have had a prior hysterectomy (27% vs 16%, p=0.02). They were less likely to have a concurrent anterior (p<0.001) or posterior repair (p<0.001). Patients undergoing the top-down procedure were less likely to experience sling exposure (p=0.02); complications in the two groups were otherwise similar.ConclusionsThe top-down approach to retropubic MUS placement was associated with lower rates of mesh erosion in this population of patients. Neither approach is associated with an increased overall risk of complications or de novo overactive bladder symptoms.

Brachial Tunneled Peripherally Inserted Central Catheters and the Risk of Catheter Complications: A Systematic Review and Meta-Analysis.

Situations involving increased workloads and stress (i.e., the COVID-19 pandemic) underline the need for healthcare professionals to minimize patient complications. In the field of vascular access, tunneling techniques are a possible solution. This systematic review and meta-analysis aimed to compare the effectiveness of tunneled Peripherally Inserted Central Catheters (tPICCs) to conventional Peripherally Inserted Central Catheters (cPICCs) in terms of bleeding, overall success, procedural time, and late complications. Randomized controlled trials without language restrictions were searched using PUBMED®, EMBASE®, EBSCO®, CINAHL®, and the Cochrane Controlled Clinical Trials Register from August 2022 to August 2023. Five relevant papers (1238 patients) were included. There were no significant differences in overall success and nerve or artery injuries between the two groups (p = 0.62 and p = 0.62, respectively), although cPICCs caused slightly less bleeding (0.23 mL) and had shorter procedural times (2.95 min). On the other hand, tPICCs had a significantly reduced risk of overall complications (p < 0.001; RR0.41 [0.31-0.54] CI 95%), catheter-related thrombosis (p < 0.001; RR0.35 [0.20-0.59] IC 95%), infection-triggering catheter removal (p < 0.001; RR0.33 [0.18-0.61] IC 95%), wound oozing (p < 0.001; RR0.49 [0.37-0.64] IC 95%), and dislodgement (p < 0.001; RR0.4 [0.31-0.54] CI 95%). The tunneling technique for brachial access appears to be safe concerning intra-procedural bleeding, overall success, and procedural time, and it is effective in reducing the risk of late complications associated with catheterization.

Efficacy of electroacupuncture in improving postoperative ileus in patients receiving colorectal surgery: a systematic review and meta-analysis.

This meta-analysis aimed to evaluate the efficacy and safety of electroacupuncture (EA) in improving postoperative ileus after colorectal surgery. Electronic databases (e.g. Medline) were screened to identify randomized controlled trials that focused on the association between EA and postoperative ileus. Time to first flatus served as the primary outcome, while the secondary outcomes included time required for the recovery of other gastrointestinal functions (e.g. bowel sound recovery), time to tolerability of liquid/solid food, postoperative pain scores, risk of overall complications, and hospital length of stay. Our meta-analysis focusing on 16 studies with a total of 1562 patients demonstrated positive associations of EA with shorter times to the first flatus [mean difference (MD): -10.1h, P <0.00001, n =1562], first defecation (MD: -11.77h, P <0.00001, n =1231), bowel sound recovery (MD: -10.76h, P <0.00001, n =670), tolerability of liquid (MD: -16.44h, P =0.0002, n =243), and solid food (MD: -17.21h, P =0.005, n =582) than those who received standard care. The use of EA was also correlated with a lower risk of overall complications (risk ratio:0.71, P =0.04, n =1011), shorter hospital length of stay (MD: -1.22 days, P =0.0001, n =988), and a lower pain score on postoperative days two (standardized MD: -0.87, P =0.009, n =665) and three (standardized MD: -0.45, P <0.00001, n =795), without a difference in time to first ambulation. Our findings showed an association between EA and enhanced gastrointestinal functional recovery and reduced pain severity following colorectal surgery, highlighting the potential benefits of incorporating EA into perioperative care to enhance recovery outcomes in this setting.

Close lateral internal sphincterotomy versus open lateral internal sphincterotomy for chronic anal fissure: a systematic review and meta-analysis

Background: Lateral internal sphincterotomy (LIS) has been the gold standard for treating chronic anal fissure (CAF) that persists despite other measures. The authors aim to evaluate the effects of the close method (CLIS) of performing LIS as compared to the open method (OLIS). Methods: Databases were searched for relevant studies and results were screened to identify eligible articles, and all concerned outcomes were pooled as odd ratio (OR) or mean difference (MD) with 95% CI in the meta-analysis models using RevMan 5.4. Results: Pooled data from 16 trials with 1,711 patients with idiopathic CAF showed that the CLIS has significant lower risk of delayed fissure healing [OR: 0.28, 95% CI (0.10, 0.77), P = 0.01], duration of hospital stay [MD: -0.82 with 95% CI (−1.07, −0.57), P &lt; 0.00001] and postoperative visual analogue pain score (VAPS) at 24 h [MD: −0.30 with 95% CI (−0.39, −0.21), P &lt; 0.00001]. Also, the risk of overall complications [OR: 0.33 with 95% CI (0.19, 0.55), P &lt; 0.0001], incontinence [OR: 0.28 with 95% CI (0.20, 0.38), P &lt; 0.00001], and postoperative pain [OR: 0.56 with 95% CI (0.35, 0.91), P = 0.02] was significantly lower with CLIS. Conclusion: CLIS is a safer option than OLIS for treating anal fissure. The risk of delayed fissure healing, incontinence, post-op pain and overall complication was significantly lower. However, the risk of surgical site infection, postoperative bleeding and recurrence did not differ. Future research with more prolonged follow-up is necessary to document recurrence reliably.

The Impact of Portal Hypertension Assessment Method on the Outcomes of Hepatocellular Carcinoma Resection: A Meta-Analysis of Matched Cohort and Prospective Studies.

Examine portal hypertension (PHT) impact on postoperative and survival outcomes in hepatocellular carcinoma (HCC) patients after liver resection (LR), specifically exploring distinctions between indirect signs and invasive measurements of PHT. PHT has historically discouraged LR in individuals with HCC due to the elevated risk of morbidity, including liver decompensation (LD). A systematic review was conducted using 3 databases to identify prospective-controlled and matched cohort studies until December 28, 2022. Focus on comparing postoperative outcomes (mortality, morbidity, and liver-related complications) and overall survival in HCC patients with and without PHT undergoing LR. Three meta-analysis models were utilized: for aggregated data (fixed-effects inverse variance model), for patient-level survival data (one-stage frequentist meta-analysis with gamma-shared frailty Cox proportional hazards model), and for pooled data (Freeman-Tukey exact and double arcsine method). Nine studies involving 1124 patients were analyzed. Indirect signs of PHT were not significantly associated with higher mortality, overall complications, PHLF or LD. However, LR in patients with hepatic venous pressure gradient (HVPG) ≥10mmHg significantly increased the risk of overall complications, PHLF, and LD. Despite elevated risks, the procedure resulted in a 5-year overall survival rate of 55.2%. Open LR significantly increased the risk of overall complications, PHLF, and LD. Conversely, PHT did not show a significant association with worse postoperative outcomes in minimally invasive LR. LR in the presence of indirect signs of PHT poses no increased risk of complications. Yet, in HVPG ≥10mmHg patients, LR increases overall morbidity and liver-related complications risk. Transjugular HVPG assessment is crucial for LR decisions. Minimally invasive approach seems to be vital for favorable outcomes, especially in HVPG ≥10mmHg patients.

The impact of hospital experience in bariatric surgery on short-term outcomes after minimally invasive esophagectomy: a nationwide analysis.

Minimally invasive esophagectomy (MIE) is a technically challenging procedure with a substantial learning curve. Composite volume of upper gastrointestinal (upper GI) procedures for cancer has been previously linked to postoperative outcomes. This study aimed to investigate an association between hospital experience in bariatric surgery and short-term outcomes in MIE. Data on esophagectomy patients between 2016 and 2020 were collected from the Dutch Upper Gastrointestinal Cancer Audit, a mandatory nationwide registry. Hospitals were categorized as bariatric or non-bariatric. Multivariable logistic regression investigated short-term postoperative outcomes, adjusting for case mix. Of 3371 patients undergoing esophagectomy in sixteen hospitals, 2450 (72.7%) underwent MIE. Bariatric hospitals (N = 6) accounted for 1057 (43.1%) MIE. Annual volume of bariatric procedures was median 523 and esophagectomies 42. In non-bariatric hospitals, volume of esophagectomies was median 52 (P = 0.145). Overall postoperative complication rate was lower in bariatric hospitals (59.2% vs. 65.9%, P < 0.001). Bariatric hospitals were associated with a reduced risk of overall complications (aOR 0.76 [95% CI 0.62-0.92]), length of hospital (aOR 0.79 [95% CI 0.65-0.95]), and ICU stay (aOR 0.81 [95% CI 0.67-0.98]) after MIE. Surgical radicality (R0) did not differ. Lymph node yield (≥ 15) was lower in bariatric hospitals (90.0% vs. 94.7%, P < 0.001). Over the years, several short-term outcomes improved in bariatric hospitals compared to non-bariatric hospitals. In this nationwide analysis, there was an association between bariatric hospitals and improved short-term outcomes after MIE. Characteristics of bariatric hospitals that could explain this phenomenon and whether this translates to other upper GI procedures may be warranted to identify.

OGC P38 The impact of hospital experience in bariatric surgery on short-term outcomes after minimally invasive oesophagectomy: a nationwide analysis

Abstract Background Minimally invasive oesophagectomy (MIO) is a technically challenging procedure with a substantial learning curve. Composite volume of upper gastrointestinal (upper GI) procedures for cancer has been previously linked to postoperative outcomes. This study aimed to investigate an association between hospital experience in bariatric surgery and short-term outcomes in MIO. Methods Data on oesophagectomy patients between 2016 and 2020 were collected from the Dutch Upper Gastrointestinal Cancer Audit, a mandatory nationwide registry. Hospitals were categorized as bariatric or non-bariatric. Dutch institutions have a mandatory annual threshold of 200 bariatric and 20 oesophagectomy procedures. Multivariable logistic regression investigated short-term postoperative outcomes, adjusting for case-mix. Results Of 3371 patients undergoing oesophagectomy in sixteen hospitals, 2450 (72.7%) underwent MIO. Bariatric hospitals (N=6) accounted for 1057 (43.1%) MIO. Overall postoperative complication rate was lower in bariatric hospitals (59.2% vs. 65.9%, P&amp;lt;0.001). Bariatric hospitals were associated with a reduced risk of overall complications (OR 0.72 [95%CI 0.60-0.87]), length of hospital (OR 0.73 [95%CI 0.61-0.87]) and ICU stay (OR 0.83 [95%CI 0.69-1.00] (P=0.046)) after MIO. Surgical radicality did not differ. Lymph node yield (≥15) was lower in bariatric hospitals (90.0% vs. 94.7%, P&amp;lt;0.001). Several short-term outcomes showed a significantly improving trend over the years in bariatric, but not non-bariatric hospitals. Conclusions In this nationwide analysis, bariatric hospitals were associated with improved short-term outcomes after MIO and further improved over the years. Characteristics of bariatric hospitals that could explain this phenomenon and whether this translates to other upper GI procedures may be warranted to identify.

The impact of sarcopenia on esophagectomy for cancer: a systematic review and meta-analysis

BackgroundEsophagectomy is the gold-standard treatment for locally advanced esophageal cancer but has high morbimortality rates. Sarcopenia is a common comorbidity in cancer patients. The exact burden of sarcopenia in esophagectomy outcomes remains unclear. Therefore, this systematic review and meta-analysis were performed to establish the impact of sarcopenia on postoperative outcomes of esophagectomy for cancer.MethodsWe performed a systematic review and meta-analysis comparing sarcopenic with non-sarcopenic patients before esophagectomy for cancer (Registration number: CRD42021270332). An electronic search was conducted on Embase, PubMed, Cochrane, and LILACS, alongside a manual search of the references. The inclusion criteria were cohorts, case series, and clinical trials; adult patients; studies evaluating patients with sarcopenia undergoing esophagectomy or gastroesophagectomy for cancer; and studies that analyze relevant outcomes. The exclusion criteria were letters, editorials, congress abstracts, case reports, reviews, cross-sectional studies, patients undergoing surgery for benign conditions, and animal studies. The meta-analysis was synthesized with forest plots.ResultsThe meta-analysis included 40 studies. Sarcopenia was significantly associated with increased postoperative complications (RD: 0.08; 95% CI: 0.02 to 0.14), severe complications (RD: 0.11; 95% CI: 0.04 to 0.19), and pneumonia (RD: 0.13; 95% CI: 0.09 to 0.18). Patients with sarcopenia had a lower probability of survival at a 3-year follow-up (RD: -0.16; 95% CI: -0.23 to -0.10).ConclusionPreoperative sarcopenia imposes a higher risk for overall complications and severe complications. Besides, patients with sarcopenia had a lower chance of long-term survival.

Common laboratory tests and their correlation with the clinical presentation and prognosis of Lemierre syndrome

IntroductionLemierre syndrome is a thromboembolic complication following an acute bacterial infection of the head/neck area, often due to anaerobes. Data on the prognostic role of laboratory parameters is lacking. MethodsWe analyzed individual-patient level data from a multinational cohort of patients with Lemierre-syndrome. Patients had an infection in the head/neck area, and contiguous vein thrombosis or septic embolism, irrespective of the causal pathogen. We studied the patterns of white blood cell count, platelet count, and C-reactive protein concentration investigating their association with baseline characteristics and in-hospital clinical outcomes (septic embolism, major bleeding, all-cause death). ResultsA total of 447 (63%) patients had complete data for analysis. White blood cells were elevated across all subgroups (median 17 × 103/μL; Q1-Q3:12-21). Median platelet count was 61 × 103/μL (Q1-Q3:30-108) with decreasing levels with increasing age. Males, patients with renal failure or cardiopulmonary impairment, and those with typical Lemierre syndrome (tonsillitis, septic thromboembolism, positivity for Fusobacterium spp.) had the lowest platelet count. Median C-reactive protein was 122 (Q1-Q3:27-248) mg/L with higher values in patients who also had more severe thrombocytopenia. The overall risk of complications was similar across subgroups of patients stratified according to white blood cell and C-reactive protein levels. Patients in the lowest third of platelet count (<42 × 103/μL) had the highest rate of complications (26%), as opposed to those in the highest third (11%), notably septic embolic events. ConclusionsCommon laboratory tests correlate with the clinical presentation of Lemierre syndrome. However, extreme values did not appear to be prognostically relevant for in-hospital complications and potentially able to improve clinical management.

Outcomes of Head and Neck Free Tissue Transfer in Renal Failure Patients.

To assess if there is increased risk of free flap failure in renal failure patients undergoing head and neck reconstruction. We seek to primarily assess free flap outcomes based on stages of chronic kidney disease (CKD) and secondarily determine increased risk for postoperative complications. Retrospective chart review was performed at five tertiary care centers. Patients were identified that had undergone microvascular free flap reconstruction of the head and neck with diagnosis of renal failure, classified as Stage 3 CKD or higher. Demographic data was collected. Outcomes in the postoperative period were examined. Seventy-three patients met inclusion criteria. The average patient age was 69 years with a male predominance (n = 48). The majority of patients had CKD Stage 3 (n = 52). Overall flap failure rate was 12.33% (n = 9, CKD stage 3 = 7.69%, CKD stage 4 = 30%, CKD stage 5 = 18%). There was an increased risk of flap failure on multivariate analysis for CKD stage 4/5 patients when compared to CKD 3 patients (p = 0.0095). When compared to matched controls, there was an increased risk of flap failure in CKD patients (p = 0.01) as well as an increased risk of overall complications (p < 0.0001). Patients with CKD undergoing head and neck reconstruction are at a higher risk of flap failure and overall complications. When comparing CKD stages there may be increased risk of flap failure in later stages of CKD compared to CKD 3. Appropriate patient counseling is recommended pre-operatively in this patient population with consideration for regional flaps in the appropriate patient. 3 Laryngoscope, 134:688-694, 2024.
