Impact of bariatric surgery on circulating irisin levels: a systematic review and meta­analysis.

This systematic review and meta-analysis evaluated changes in circulating irisin levels after bariatric surgery. A systematic search was performed across Embase, Scopus, PubMed, and Web of Science for this study. The meta-analysis was conducted using Comprehensive Meta-Analysis (CMA) V4 software. The overall effect size was depicted through a random-effects meta-analysis and the leave-one-out method. The meta-analysis, which included 13 studies with a total of 407 participants, showed a statistically non-significant reduction in circulating irisin levels following bariatric surgery (SMD: - 0.089, 95% CI - 0.281, 0.102, 95% PI: - 0.790, 0.611, p = 0.360; I2:70.56). Our research found no significant change in irisin levels after bariatric surgery. Moreover, these findings were not associated with the type of surgery or the duration of follow-up.

Comparing Accuracy of Night Radiology Interpretations for Pediatric Trauma: Radiology Residents Versus Attending Teleradiologists.

Background: Overnight radiology coverage for pediatric trauma patients (PTPs) is addressed with a combination of on-call radiology residents (RRs) and/or attending teleradiologists (ATs); however, the accuracy of these two groups has not been investigated for PTPs. We aimed to compare the accuracy of RRs vs AT interpretations of computed tomography (CT) scans for PTPs. Methods: Pediatric trauma patients (<18 years old) at a single level-I adult/level-II pediatric trauma center were studied in a retrospective analysis (3/2019-5/2020). Computed tomography scans interpreted by both RRs and ATs were included. Radiology residents were compared to ATs for time to interpretation (TTI) and accuracy compared to faculty attending radiologist interpretation, using the validated RADPEER scoring system. Additionally, RR and AT accuracies were compared to a previously studied adult cohort during the same time-period. Results: 42 PTPs (270 interpretations) and 1053 adults (8226 interpretations) were included. Radiology residents had similar rates of discrepancy (13.3% vs 13.3%), major discrepancy (4.4% vs 4.4%), missed findings (9.6% vs 12.6%), and overcalls (3.7% vs .7%) vs ATs (all P > .05). Mean TTI was shorter for RRs (55.9 vs 90.4 minutes, P < .001). Radiology residents had a higher discrepancy rate for PTPs (13.3% vs 7.5%, P = .01) than adults. Attending teleradiologists had a similar discrepancy rate for PTPs and adults (13.3% vs 8.9%, P = .07). Discussion: When interpreting PTP CT imaging, RRs had similar discrepancy rates but faster TTI than ATs. Radiology residents had a higher discrepancy rate for PTP CTs than RR interpretation of adult patients, indicating both RRs and ATs need more focused training in the interpretation of PTP studies.

Bariatric Surgery Improves Serum CD40L Levels as a Predictor of Cardiovascular Risk: Systematic Review and Meta-analysis.

CD40 and its ligand have been recently implicated in the pathogenesis of cardiovascular disease (CVD). This meta-analysis examined the effect of bariatric surgery in reducing circulating CD40L levels. A systematic review was performed using Embase, Google Scholar, PubMed, Scopus, and Web of Science. The meta-analysis was provided by Comprehensive Meta-Analysis (CMA) V4 software. The overall effect size was detected by a random-effects meta-analysis and the leave-one-out approach. Random-effects meta-analysis of 7 studies including 191 subjects showed a significant reduction in CD40L after bariatric surgery (standardized mean difference (SMD), - 0.531; 95% CI, - 0.981, - 0.082; p = 0.021; I2, 87.00). Circulating levels of CD40L are decreased after bariatric surgery which may represent a mechanism for improvement of metabolic profile.

Correlation of the Endoscopic Gastroesophageal Flap Valve with Pathologic Reflux.

BACKGROUND: The Hill classification characterizes the geometry of gastroesophageal junction and Hill grades (HGs) III and IV have a high association with pathologic reflux. This study aimed to understand the use of the Hill classification and correlate the prevalence of pathologic reflux across different HGs. STUDY DESIGN: A retrospective review of 477 patients who underwent upper endoscopy and BRAVO pH monitoring between August 2018 and October 2021 was performed. These charts were reviewed for endoscopic findings for hiatal hernia and association of HGs with pathologic reflux, defined as an abnormal esophageal acid exposure time (AET) of ≥4.9%. RESULTS: Of 477 patients, 252 (52.8%) had an HG documented on the endoscopy report. Of the 252 patients, 61 had HG I (24.2%), 100 had HG II (39.7%), 61 had HG III (24.2%), and 30 had HG IV (11.9%). The proportion of patients with abnormal AET increases with increasing HGs (p < 0.001) as follows: I (39.3%), II (52.5%), III (67.2%), and IV (79.3%). The mean overall AET is as follows: HG I (5.5 ± 6%), HG II (7.0 ± 5.9%), HG III (10.2 ± 10.3%), and HG IV (9.5 ± 5.5%). The proportion of patients with hiatal hernia was 18% for HG I, 28% for HG II, 39.3% for HG III, and 80% for HG IV. CONCLUSIONS: Use of the Hill classification in clinical practice is low. There is an association of increasing HGs with increasing proportion of patients with abnormal AET. There is a high proportion of patients within HGs I and II with documented pathologic reflux and the presence of a hiatal hernia as observed on endoscopic examination. Our study suggests that endoscopic grading of the gastroesophageal junction may not adequately differentiate between normal vs abnormal reflux status, particularly for HGs I and II.

Outcomes of Colectomy and Proctectomy According to Surgeon Training: General vs Colorectal Surgeons.

BACKGROUND: Colectomies and proctectomies are commonly performed by both general surgeons (GS) and colorectal surgeons (CRS). The aim of our study was to examine the outcomes of elective colectomy, urgent colectomy, and elective proctectomy according to surgeon training. STUDY DESIGN: Data were obtained from the Vizient database for adults who underwent elective colectomy, urgent colectomy, and elective proctectomy from 2020 to 2022. Operations performed in the setting of trauma and patients within the database's highest relative expected mortality risk group were excluded. Outcomes were compared according to surgeon's specialty: GS vs CRS. The primary outcome was in-hospital mortality. The secondary outcome was in-hospital complication rate. Data were analyzed using multivariate logistic regression. RESULTS: Of 149,516 elective colectomies, 75,711 (50.6%) were performed by GS and 73,805 (49.4%) by CRS. Compared with elective colectomies performed by CRS, elective colectomies performed by GS had higher rates of complications (4.9% vs 3.9%, odds ratio [OR] 1.23, 95% CI 1.17 to 1.29, p < 0.01) and mortality (0.5% vs 0.2%, OR 2.06, 95% CI 1.72 to 2.47, p < 0.01). Of 71,718 urgent colectomies, 54,680 (76.2%) were performed by GS, whereas 17,038 (23.8%) were performed by CRS. Compared with urgent colectomies performed by CRS, urgent colectomies performed by GS were associated with higher rates of complications (12.1% vs 10.4%, OR 1.14, 95% CI 1.08 to 1.20, p < 0.01) and mortality (5.1% vs 2.3%, OR 2.08, 95% CI 1.93 to 2.23, p < 0.01). Of 43,749 elective proctectomies, 28,458 (65.0%) were performed by CRS and 15,291 (35.0%) by GS. Compared with proctectomies performed by CRS, those performed by GS were associated with higher rates of complications (5.3% vs 4.4%, OR 1.16, 95% CI 1.06 to 1.27, p < 0.01) and mortality (0.3% vs 0.2%, OR 1.49, 95% CI 1.02 to 2.20, p = 0.04). CONCLUSIONS: In this nationwide study, colectomies and proctectomies performed by CRS were associated with improved outcomes compared with GS. Hospitals without a CRS on staff should consider prioritizing recruiting CRS specialists.

Improvement of Triglyceride-Glucose Index Following Bariatric Surgery: a Systematic Review and Meta-analysis.

BACKGROUND: Bariatric surgery is an effective intervention for the management of severe obesity and its associated comorbidities, including metabolic abnormalities. This meta-analysis aimed to evaluate the impact of bariatric surgery on the triglyceride-glucose (TyG) index, a novel marker of insulin resistance and metabolic syndrome. METHODS: A systematic search was conducted in Embase, PubMed, Web of Science, and Scopus. The meta-analysis was performed using Comprehensive Meta-Analysis (CMA) V4 software. The overall effect size was determined by a random-effects meta-analysis and the leave-one-out approach. RESULTS: A total of 9 trials including 1620 individuals confirmed a significant reduction in TyG following bariatric surgery (weighted mean difference (WMD) - 0.770, 95% CI - 1.006, - 0.534, p < 0.001). In a sub-analysis according to the type of bariatric surgery there was a significant reduction in TyG index for Roux-en-Y gastric bypass (WMD - 0.775, 95% CI - 1.000, - 0.550, p < 0.001), and sleeve gastrectomy (WMD - 0.920, 95% CI - 1.368, - 0.473, p < 0.001). In a sub-analysis according to the follow-up duration there was similarly a significant reduction in TyG index for both < 12 months (WMD - 1.645, 95% CI - 2.123, - 1.167, p < 0.001), and ≥ 12 months follow-up (WMD - 0.954, 95% CI - 1.606, - 0.303, p < 0.001). CONCLUSION: The results of this meta-analysis demonstrated a significant reduction in the TyG index following bariatric surgery, indicating improved insulin sensitivity and metabolic health. These findings highlight the potential of bariatric surgery as a valuable therapeutic option for individuals with obesity and its metabolic consequences.

Open vs robotic gastrectomy with D2 lymphadenectomy: a propensity score-matched analysis on 1469 patients from the IMIGASTRIC prospective database.

BACKGROUND: Comparative data on D2-robotic gastrectomy (RG) vs D2-open gastrectomy (OG) are lacking in the Literature. Aim of this paper is to compare RG to OG with a focus on D2-lymphadenectomy. STUDY DESIGN: Data of patients undergoing D2-OG or RG for gastric cancer were retrieved from the international IMIGASTRIC prospective database and compared. RESULTS: A total of 1469 patients were selected for inclusion in the study. After 1:1 propensity score matching, a total of 580 patients were matched and included in the final analysis, 290 in each group, RG vs OG. RG had longer operation time (210 vs 330 min, p < 0.0001), reduced intraoperative blood loss (155 vs 119.7 ml, p < 0.0001), time to liquid diet (4.4 vs 3 days, p < 0.0001) and to peristalsis (2.4 vs 2 days, p < 0.0001), and length of postoperative stay (11 vs 8 days, p < 0.0001). Morbidity rate was higher in OG (24.1% vs 16.2%, p = 0.017). CONCLUSION: RG significantly expedites recovery and reduces the risk of complications compared to OG. However, long-term survival is similar.

Obese adolescents have higher risk for severe lower extremity fractures after falling.

INTRODUCTION: Reports vary on the impact of obesity on the incidence of lower extremity fractures after a fall. We hypothesized that obese adolescents (OA) presenting after a fall have a higher risk of any and severe lower extremity fractures compared to non-OAs. METHODS: A national database was queried for adolescents (12-17 years old) after a fall. Primary outcome included lower extremity fracture. Adolescents with a body mass index (BMI) ≥ 30 (OA) were compared to adolescents with a BMI < 30 (non-OA). RESULTS: From 20,264 falls, 2523 (12.5%) included OAs. Compared to non-OAs, the rate of any lower extremity fracture was higher for OAs (51.5% vs. 30.7%, p < 0.001). This remained true for lower extremity fractures at all locations (all p < 0.05). After adjusting for sex and age, associated risk for any lower extremity fracture (OR 2.41, CI 2.22-2.63, p < 0.001) and severe lower extremity fracture (OR 1.31, CI 1.15-1.49, p < 0.001) was higher for OAs. This remained true in subset analyses of ground level falls (GLF) and falls from height (FFH) (all p < 0.05). CONCLUSIONS: Obesity significantly impacts adolescents' risk of all types of lower extremity fractures after FFH or GLF. Hence, providers should have heightened awareness for possible lower extremity fractures in OAs. LEVEL OF EVIDENCE: IV.

Impact of COVID-19 Pandemic on Management and Outcomes of Acute Cholecystitis at US Academic Centers.

BACKGROUND: The COVID-19 pandemic has had wide-ranging effects on management of medical conditions. Many hospitals encountered staffing shortages, limited operating room availability, and shortage of hospital beds. There was increased psychological stress and fear of contracting COVID-19 infection, leading to delay in medical care for various disease processes. The objective of this study was to examine changes in management and outcomes attributed to the COVID-19 pandemic in patients presenting with acute calculus cholecystitis at US academic centers. STUDY DESIGN: Using the Vizient database, patients with the diagnosis of acute calculus cholecystitis who underwent intervention during the 15 months before the pandemic (prepandemic, October 2018 to December 2019) were compared with 15 months during the pandemic (pandemic, March 2020 to May 2021). Outcomes measures included demographics, characteristics, type of intervention, length of stay, in-hospital mortality, and direct cost. RESULTS: There were 146,459 patients with acute calculus cholecystitis identified (prepandemic: 74,605 vs pandemic: 71,854). Patients in the pandemic group were more likely to undergo medical management (29.4% vs 31.8%; p < 0.001) or percutaneous cholecystostomy tube placement (21.5% vs 18%; p < 0.001) and less likely to undergo laparoscopic cholecystectomy (69.8% vs 73.0%; p < 0.001). Patients in the pandemic group who underwent procedural intervention had longer length of stay (6.5 days vs 5.9 days; p < 0.001), higher in-hospital death (3.1% vs 2.3%; p < 0.001), and higher cost ($14,609 vs $12,570; p < 0.001). CONCLUSIONS: In this analysis of patients with acute calculus cholecystitis, there were distinct changes in the management and outcomes of patients due to the COVID-19 pandemic. Changes in the type of intervention and outcomes are likely related to delayed presentation with increases in the severity and complexity of the disease.

Analysis of Veno-Venous Extracorporeal Membrane Oxygenation for COVID-19 Compared to Non-COVID Etiologies.

OBJECTIVE: This study analyzed the characteristics and outcomes of veno-venous (V-V) extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS) due to COVID-19 versus non-COVID causes at US academic centers. BACKGROUND DATA: V-V ECMO support has been utilized for COVID-19 patients with ARDS since the beginning of the pandemic. Mortality for ECMO in COVID-19 has been reported to be high but similar to reported mortality for ECMO support for non-COVID causes of respiratory failure. METHODS: Using ICD-10 codes, data of patients who underwent V-V ECMO for COVID-19 ARDS were compared with patients who underwent V-V ECMO for non-COVID causes between April 2020 and December 2022. The primary outcome was in-hospital mortality. Secondary outcome measures included length of stay and direct cost. Multivariate logistic regression modeling was performed to analyze differences in mortality between COVID and non-COVID groups, adjusting for other important risk factors (age, sex, and race/ethnicity). RESULTS: We identified and compared 6382 patients who underwent V-V ECMO for non-COVID causes to 6040 patients who underwent V-V ECMO for COVID-19. There was a significantly higher proportion of patients aged ≥ 65 years who underwent V-V ECMO in the non-COVID group compared with the COVID group (19.8% vs. 3.7%, respectively, P <0.001). Compared with patients who underwent V-V ECMO for non-COVID causes, patients who underwent V-V ECMO for COVID had increased in-hospital mortality (47.6% vs. 34.5%, P <0.001), length of stay (46.5±41.1 days vs. 40.6±46.1, P <0.001), and direct hospitalization cost ($207,022±$208,842 vs. $198,508±205,510, P =0.02). Compared with the non-COVID group, the adjusted odds ratio (OR) for in-hospital mortality in the COVID group was 2.03 (95% CI: 1.87-2.20, P <0.001). In-hospital mortality for V-V ECMO in COVID-19 improved during the study time period (50.3% in 2020, 48.6% in 2021, and 37.3% in 2022). However, there was a precipitous drop in the ECMO case volume for COVID starting in quarter 2 of 2022. CONCLUSIONS: In this nationwide analysis, COVID-19 patients with ARDS requiring V-V ECMO support had increased mortality compared with patients who underwent V-V ECMO for non-COVID etiologies.

Readmission and Disposition in Patients With Malignant Bowel Obstructions Following Gastrostomy Tube.

BACKGROUND: Patients with peritoneal carcinomatosis (PC) can develop malignant bowel obstructions (MBOs) requiring inpatient admission and nasogastric tube decompression. Palliative decompressive gastrostomy tubes (G-tubes) may affect patient disposition, allowing for self-management and reduction in inpatient services. Therefore, we sought to assess disposition and inpatient readmission rates in patients admitted with PC and MBO following G-tube placement. METHODS: The Vizient® Clinical Data Base was queried for inpatient admissions from October 2018 to May 2022 utilizing ICD-10 codes to identify patients admitted with PC and bowel obstruction, with or without G-tube placement. Demographics and hospital outcomes were recorded. Descriptive statistics and multivariate logistic regression analysis were performed. RESULTS: From 750 patients, 59 (7.9%) had a G-tube placed. Compared to patients without G-tubes, those with G-tubes had lower rates of disposition to home (32.2% vs 70.0%, P < .001) and higher rates of disposition to hospice (home: 30.5% vs 7.8%, P < .001, facility: 10.2% vs 3.9%, P = .02). There was no significant difference in the rate (17.3% vs 22.3%, P = .40) or risk (OR = 1.44, 95% CI .69-3.01) of 30-day readmissions with G-tubes. However, palliative care consultation (OR 33.77, 95% CI 19.16-59.52) and G-tube placement (OR 5.82, 95% CI 2.56-13.25) were independent predictors for hospice. DISCUSSION: Placement of G-tubes in patients with PC and MBO was associated with higher rates of disposition to hospice but there is no difference in 30-day readmission rates compared to those without G-tubes. Further prospective studies are needed to understand the role of G-tube placement in patients with MBO in relation to outcomes and disposition.

Weight Regain After Bariatric Surgery: Scope of the Problem, Causes, Prevention, and Treatment.

PURPOSE OF REVIEW: Although bariatric surgery is the most effective treatment of severe obesity, a proportion of patients experience clinically significant weight regain (WR) with further out from surgery. The purpose of this review is to summarize the prevalence, predictors, and causes of weight regain. RECENT FINDINGS: Estimating the prevalence of WR is limited by a lack of consensus on its definition. While anatomic failures such as dilated gastric fundus after sleeve gastrectomy and gastro-gastric fistula after Roux-en-Y gastric bypass can lead to WR, the most common causes appear to be dysregulated/maladaptive eating behaviors, lifestyle factors, and physiological compensatory mechanisms. To date, dietary, supportive, behavioral, and exercise interventions have not demonstrated a clinically meaningful impact on WR, and there is limited evidence for pharmacotherapy. Future studies should be aimed at better defining WR to begin to understand the etiologies. Additionally, there is a need for non-surgical interventions with demonstrated efficacy in rigorous randomized controlled trials for the prevention and reversal of WR after bariatric surgery.

Development and Validation of a Renal Replacement after Trauma Scoring Tool.

BACKGROUND: Stress on the healthcare system requires careful allocation of resources such as renal replacement therapy (RRT). The COVID-19 pandemic generated difficulty securing access to RRT for trauma patients. We sought to develop a renal replacement after trauma (RAT) scoring tool to help identify trauma patients who may require RRT during their hospitalization. STUDY DESIGN: The 2017 to 2020 TQIP database was divided into a derivation (2017 to 2018 data) and validation (2019 to 2020 data) set. A 3-step methodology was used. Adult trauma patients admitted from the emergency department to the operating room or ICU were included. Patients with chronic kidney disease, transfers from another hospital, and emergency department death were excluded. Multiple logistic regression models were created to determine the risk for RRT in trauma patients. The weighted average and relative impact of each independent predictor was used to derive a RAT score, which was validated using area under receiver operating characteristic curve (AUROC). RESULTS: From 398,873 patients in the derivation and 409,037 patients in the validation set, 11 independent predictors of RRT were included in the RAT score derived with scores ranging from 0 to 11. The AUROC for the derivation set was 0.85. The rate of RRT increased to 1.1%, 3.3%, and 20% at scores of 6, 8, and 10, respectively. The validation set AUROC was 0.83. CONCLUSIONS: RAT is a novel and validated scoring tool to help predict the need for RRT in trauma patients. With future improvements including baseline renal function and other variables, the RAT tool may help prepare for the allocation of RRT machines/staff during times of limited resources.

Hiatal hernia repair with transoral incisionless fundoplication versus Nissen fundoplication for gastroesophageal reflux disease: A retrospective study.

Background and study aims Concomitant hiatal hernia (HH) repair with transoral incisionless fundoplication (TIF) is a therapeutic option for patients with HH > 2 cm and gastroesophageal reflux disease (GERD). Data comparing this approach with laparoscopic Nissen fundoplication (LNF) are lacking. We performed an exploratory analysis to compare these two approaches' adverse events (AEs) and clinical outcomes. Patients and methods This was a multicenter retrospective cohort study of HH repair followed by LNF versus HH repair followed by TIF in patients with GERD and moderate HH (2-5 cm). AEs were assessed using the Clavien-Dindo classification. Symptoms (heartburn/regurgitation, bloating, and dysphagia) were compared at 6 and 12 months. Results A total of 125 patients with HH repair with TIF and 70 with HH repair with LNF were compared. There was no difference in rates of discontinuing or decreasing proton pump inhibitor use, dysphagia, esophagitis, disrupted wrap, and HH recurrence between the two groups ( P  > 0.05). The length of hospital stay (1 day vs. 2 days), 30-day readmission rate (0 vs. 4.3 %), early AE rate (0 vs. 18.6 %), and early serious AE rate (0 vs. 4.3 %) favored TIF (all P  < 0.05). The rate of new or worse than baseline bloating was lower in the TIF group at 6 months (13.8 % vs. 30.0 %, P  = 0.009). Conclusions Concomitant HH repair with TIF is feasible and associated with lower early and serious AEs compared to LNF. Further comparative efficacy studies are warranted.

Transoral incisionless fundoplication for recurrent symptoms after laparoscopic fundoplication.

BACKGROUND: Revision of a failed laparoscopic fundoplication carries higher risk of complication and lower chance of success compared to the original surgery. Transoral incisionless fundoplication (TIF) may be an endoscopic alternative for select GERD patients without need of a moderate/large hiatal hernia repair. The aim of this study was to assess feasibility, efficacy, and safety of TIF 2.0 after failed laparoscopic Nissen or Toupet fundoplication (TIFFF). METHODS: This is a multicenter retrospective cohort study of patients who underwent TIFFF between September 2017 and December 2020 using TIF 2.0 technique (EsophyX Z/Z+) performed by gastroenterologists and surgeons. Patients were included if they had (1) recurrent GERD symptoms, (2) pathologic reflux based upon pH testing or Grade C/D esophagitis or Barrett's esophagus, and (3) hiatal hernia ≤ 2 cm. The primary outcome was improvement in GERD Health-Related Quality of Life (GERD-HRQL) post-TIFFF. The TIFFF cohort was also compared to a similar surgical re-operative cohort using propensity score matching. RESULTS: Twenty patients underwent TIFFF (median 4.1 years after prior fundoplication) and mean GERD-HRQL score improved from 24.3 ± 22.9 to 14.75 ± 21.6 (p = 0.014); mean Reflux Severity Index (RSI) score improved from 14.1 ± 14.6 to 9.1 ± 8.0 (p = 0.046) with 8/10 (80%) of patients with normal RSI (< 13) post-TIF. Esophagitis healed in 78% of patients. PPI use decreased from 85 to 55% with 8/20 (45%) patients off of PPI. Importantly, mean acid exposure time decreased from 12% ± 17.8 to 0.8% ± 1.1 (p = 0.028) with 9/9 (100%) of patients with normalized pH post-TIF. There were no statistically significant differences in clinical efficacy outcomes between TIFFF and surgical revision, but TIFFF had significantly fewer late adverse events. CONCLUSION: Endoscopic rescue with TIF is a safe and efficacious alternative to redo laparoscopic surgery in symptomatic patients with appropriate anatomy and objective evidence of persistent or recurrent reflux.

The DEPARTS Score: A Novel Tool for Predicting Discharge Disposition in Geriatric Trauma Patients.

BACKGROUND: Geriatric trauma patients (GTPs) represent a high-risk population for needing post-acute care, such as skilled nursing facilities (SNFs) and long-term acute care hospitals (LTACs), due to a combination of traumatic injuries and baseline functional health. As there is currently no well-established tool for predicting these needs, we aimed to create a scoring tool that predicts disposition to SNFs/LTACs in GTPs. METHODS: The adult 2017 Trauma Quality Improvement Program database was divided at random into two equal sized sets (derivation and validation sets) of GTPs >65 years old. First, multiple logistic regression models were created to determine risk factors for discharge to a SNF/LTAC in admitted GTPs. Second, the weighted average and relative impact of each independent predictor was used to derive a DEPARTS (Discharge of Elderly Patients After Recent Trauma to SNF/LTAC) score. We then validated the score using the area under the receiver-operating curve (AROC). RESULTS: Of 66 479 patients in the derivation set, 36 944 (55.6%) were discharged to a SNF/LTAC. Number of comorbidities, fall mechanism, spinal cord injury, long bone fracture, and major surgery were each independent predictors for discharge to SNF/LTAC, and a DEPARTS score was derived with scores ranging from 0 to 19. The AROC for this was .74. In the validation set, 66 477 patients also had a SNF/LTAC discharge rate of 55.7%, and the AROC was .74. DISCUSSION: The DEPARTS score is a good predictor of SNF/LTAC discharge for GTPs. Future prospective studies are warranted to validate its accuracy and clinical utility in preventing delays in discharge.

Night Radiology Coverage for Trauma: Residents, Teleradiology, or Both?

BACKGROUND: Overnight radiology coverage for trauma patients is often addressed with a combination of on-call radiology residents (RR) and a teleradiology service; however, the accuracy of these 2 readers has not been studied for trauma. We aimed to compare the accuracy of RR versus teleradiologist interpretations of CT scans for trauma patients. STUDY DESIGN: A retrospective analysis (March 2019 through May 2020) of trauma patients presenting to a single American College of Surgeons Level I trauma center was performed. Patients whose CT scans were performed between 10 pm to 8 am were included, because their scans were interpreted by both a RR and teleradiologist. Interpretations were compared with the final attending faculty radiologist's interpretation and graded for accuracy based on the RADPEER scoring system. Discrepancies were characterized as traumatic injury or incidental findings and missed findings or overcalls. Turnaround time was also compared. RESULTS: A total of 1,053 patients and 8,226 interpretations were included. Compared with teleradiologists, RR had a lower discrepancy (7.7% vs 9.0%, p = 0.026) and major discrepancy rate (3.8% vs 5.2%, p = 0.003). Among major discrepancies, RR had a lower rate of traumatic injury discrepancies (3.2% vs 4.4%, p = 0.004) and missed findings (3.4% vs 5.1%, p < 0.001), but a higher rate of overcalls (0.5% vs 0.1%, p < 0.001) compared with teleradiologists. The mean turnaround time was shorter for RR (51.3 vs 78.8 minutes, p < 0.001). The combination of both RR and teleradiologist interpretations had a lower overall discrepancy rate than RR (5.0% vs 7.7%, p < 0.001). CONCLUSIONS: This study identified lower discrepancy rates and a faster turnaround time by RR compared with teleradiologists for trauma CT studies. The combination of both interpreters had an even lower discrepancy rate, suggesting this combination is optimal when an in-house attending radiologist is not available.

Variation of Laparoscopic Roux-en-Y Gastric Bypass Techniques: a Survey of 518 Bariatric Surgeons.

INTRODUCTION: Surgical technique varies dramatically in the performance of laparoscopic Roux-en-Y gastric bypass (LRYGB) and these differences can potentially lead to variation in outcomes. The objective of this study was to characterize surgical techniques used during LRYGB. METHODS: An anonymous 44-question survey was distributed by email to all bariatric surgeons with membership in the ASMBS, SAGES, and ACS from April to June 2020. Questions were designed to evaluate surgeon demographics, experience, and variation of techniques. Only surgeons who performed LRYGB within the past year were included for analysis. RESULTS: A total of 534 (18.8%) surgeons responded and the majority (97.0%) reported performing LRYGB in the past year. Surgeons were predominantly from the USA (77.8%). For preoperative work-up, 20.1% performed upper gastrointestinal series while 60.8% performed esophagogastroduodenoscopy. Limb length evaluation revealed mean Roux and biliopancreatic limb lengths of 124.1 ± 29.4 cm and 67.4 ± 32.2 cm, respectively. The gastrojejunostomy was most commonly formed using a linear stapler with handsewn closure of the common enterotomy (53.1%) and the jejunojejunostomy using a linear stapled anastomotic technique with handsewn closure of the common enterotomy (60.6%). The majority of surgeons closed the jejunojejunostomy mesenteric defect (91.1%) and one of the antecolic or retrocolic mesenteric defects (65.1%). Intraoperative leak tests were performed in 95.9% of cases. Only 22.1% of surgeons routinely performed upper gastrointestinal swallow studies postoperatively. CONCLUSIONS: There are wide variations in pre- and intraoperative practice patterns for LRYGB. Further clinical trials designed to evaluate the impact of these practice pattern differences on patient outcomes are warranted.

First report from the American Society of Metabolic and Bariatric Surgery closed-claims registry: prevalence, causes, and lessons learned from bariatric surgery medical malpractice claims.

BACKGROUND: Bariatric surgery has demonstrated sustained improvements in quality. Malpractice closed claims have been offered as a means of assessing quality. Few studies have investigated malpractice closed claims and opportunities for improvement in bariatric surgery. OBJECTIVES: To examine the prevalence and causes of malpractice claims with examination of prospects for quality improvement. SETTING: University hospital, United States; private practice. METHODS: Four national malpractice insurers participated in the closed-claims registry. Data regarding patients, staff, procedures, and hospital status were gathered from closed-claims files. Following data collection, a clinical summary of each closed claim was collected and later assessed by an expert panel on the basis of the following: contributing diagnosis and treatment events; whether complications were potentially preventable by the surgeon; the role of language, fatigue, distraction, workload, or teaching hospital/trainee supervision; communication concerns; and final care determination. RESULTS: A total of 175 closed claims were collected from index bariatric surgeries within the period from 2006-2014. Of these, 75.9% of surgeons were board certified and 43.3% of the hospitals were accredited for bariatric surgery. Most clinical complications after bariatric surgery that led to malpractice lawsuits were mortality (35.1%) and leaks (17.5%). While they were not the common cause for malpractice suits, bleeding (5.3%), retained foreign body (5.3%), and vascular injury (4.4%) occurred at higher rates than national averages. CONCLUSION: Prevalence of malpractice claims regarding bariatric surgery is low. Failure to diagnose, delay in treatment, postoperative care, and communication domain responses indicate future opportunities for improvement.

Surgical Outcome in Laparoscopic Abdominal Surgical Operations with Clostridium Difficile Infection.

Introduction: Postoperative Clostridium difficile infection (CDI) has associated morbidity, but it is unknown how it impacts different operations. We sought to determine the incidence and postoperative morbidity following abdominal surgery.Method: The National Surgical Quality Improvement Program database (2015-2019) was utilized to evaluate adult (≥18 years-old) patients who developed CDI following laparoscopic abdominal operations. Univariate and multivariate analysis were performed to evaluate outcomes.Results: A total of 973 338 patients were studied and the overall incidence of CDI was .3% within 30 days of operation. Colorectal surgery had the highest incidence of CDI (1601/167 949,1.0%) with significantly longer mean length of stay (LOS) (8.0 days± 9.0, P < .01) compared to other surgical procedures. CDI patients also had a longer mean length of stay (6.6± 8.0 vs 2.1 ± 3.6 days, P < .01) and increased mortality (1.8% vs .2%, AOR: 4.64, CI: 3.45-5.67, P < .01) compared to patients without CDI.Conclusions: This national analysis demonstrates that CDI is a significant complication following abdominal surgery and is associated with increased LOS and mortality. Furthermore, laparoscopic colorectal surgery appears to have the greatest risk of CDI. Future research is needed to determine the exact cause in order to decrease the incidence of CDI by reconsidering the protocol of antibiotic use within the high-risk population.
