Abstract
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.

[PMID: 38743243 DOI: 10.1007/s13304-024-01866-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Accepted: 05/03/2024] [Indexed: 05/16/2024]
Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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 2020-2022. 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 to elective colectomies performed by CRS, elective colectomies performed by GS had higher rates of complications(4.9% vs. 3.9%, OR1.23, 95%CI 1.17-1.29,p<.01) and mortality(0.5% vs. 0.2%, OR2.06, 95%CI 1.72-2.47,p<.01). Of 71,718 urgent colectomies, 54,680(76.2%) were performed by GS, while 17,038(23.8%) were performed by CRS. Compared to urgent colectomies performed by CRS, urgent colectomies performed by GS were associated with higher rates of complications(12.1% vs. 10.4%, OR1.14, 95%CI 1.08-1.20,p<.01) and mortality (5.1% vs. 2.3%, OR2.08, 95%CI 1.93-2.23,p<.01). Of 43,749 elective proctectomies, 28,458(65.0%) were performed by CRS and 15,291(35.0%) by GS. Compared to proctectomies performed by CRS, those performed by GS were associated with higher rates of complications (5.3% vs. 4.4%, OR1.16, 95%CI 1.06-1.27,p<.01) and mortality(0.3% vs. 0.2%, OR1.49, 95%CI 1.02-2.20,p=.04). CONCLUSIONS In this nationwide study, colectomies and proctectomies performed by CRS were associated with improved outcomes compared to GS. Hospitals without a CRS on staff should consider prioritizing recruiting CRS specialists.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVE Prognostic models proposed for cirrhotic patients' survival have not been satisfactorily investigated in the Vietnam population, especially in the medium-term period. PATIENTS AND METHODS In this prospective study, we enrolled a total of 904 patients admitted to Hepato-Gastroenterology Center, Bach Mai Hospital from December 2019 to November 2021 and calculated their CP, MELD, MELD-Na score, IMELD, Refit MELD, and Refit MELD-Na after 2-year follow-up to compare their survival prognosis. RESULTS The mean age of the patients was 53.8 ±10.8 years, and males constituted 91%. Compared with the surviving group, deceased patients had statistically significant lower albumin, higher INR, serum bilirubin, and creatinine levels with higher means of all prognostic scores. RefitMELD score had the highest AUC (0.768), followed by MELD (0.766), and the lowest belonged to RefitMELDNa (0.669). CONCLUSIONS In conclusion, deceased patients had significantly higher values of Child-Pugh score and all MELD-based scores than survival. RefitMELD is the most reliable scoring system to predict 2-year mortality in patients with decompensated liver cirrhosis.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND: TB control remains a serious public health problem, compounded by poor treatment adherence, which increases the likelihood of onward transmission. We evaluated the effectiveness of medication event reminder monitoring (MERM) upon treatment adherence in a high TB burden setting.METHODS: We conducted an open-label parallel group randomised controlled trial among pulmonary TB adults. Participants were provided with a MERM device to store their medications. In the intervention arm, the devices were set to provide daily medication intake reminders. Primary outcome was the proportion of patient-months in which at least 6/30 doses were missed. Secondary outcomes included 1) the proportion of patient-months in which at least 14/30 doses were missed, and 2) the proportion of doses missed.RESULTS: Of 2,142 patients screened, 798 (37.3%) met the inclusion criteria and 250 participants were enrolled. The mean ratio (MR) for poor adherence between the intervention and control groups was 0.72 (95% CI 0.55-0.86). The intervention was also associated with a reduction in the proportion of patients missing at least 14/30 doses (MR 0.61, 95% CI 0.54-0.68) and the percentage of total doses missed (MR 0.75, 95% CI 0.68-0.80).CONCLUSION: MERM is effective in improving TB treatment adherence in a resource-limited environment.

Abstract
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.

Abstract
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.

Transoral incisionless fundoplication for recurrent symptoms after laparoscopic fundoplication. Surg Endosc 2023; 37:3701-3709. [PMID: 36650353 DOI: 10.1007/s00464-023-09880-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Accepted: 01/08/2023] [Indexed: 01/19/2023]
Abstract
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.

Hiatal hernia repair with transoral incisionless fundoplication versus Nissen fundoplication for gastroesophageal reflux disease: A retrospective study. Endosc Int Open 2023; 11:E11-E18. [PMID: 36618876 PMCID: PMC9812651 DOI: 10.1055/a-1972-9190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 10/19/2022] [Indexed: 01/06/2023] Open
Abstract
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.

Abstract
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.

Abstract
Current guidelines recommend neoadjuvant (NAC) and/or adjuvant chemotherapy for locally advanced gastric cancers (LAGCs). However, the choice and duration of NAC regimen is standardized, rather than personalized to biologic response, despite the availability of several different classes of agents for the treatment of gastric cancer (GC). The current trial will use a tumor-informed ctDNA assay (Signatera™) and monitor response to NAC. Based on ctDNA kinetics, the treatment regimen is modified. This is a prospective single center, single arm, open label study in clinical stage IB-III GC. ctDNA is measured at baseline and repeated every 8 weeks. Imaging is performed at the same intervals. The primary endpoint is the feasibility of this approach, defined as percentage of patients completing gastrectomy.

Abstract
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.

Abstract
Introduction The coronavirus disease 2019 (COVID-19) pandemic continues to spread globally and as of February 4, 2021, there are more than 26 million confirmed cases and more than 440,000 deaths in the United States (US). A top priority of the Centers for Disease Control and Prevention (CDC) is to identify risk factors for severe COVID-19 illness. The objective of this study was to analyze the characteristics and outcomes of COVID-19 adults who were managed in an outpatient setting compared to patients who required hospitalization at US academic centers. Methods Using the Vizient clinical database, Discharge records of adults with a diagnosis of COVID-19 between March 1, 2020 and January 31, 2021 were reviewed. Outcome measures included demographics, characteristics, rate of hospitalization, and mortality, and data were analyzed based on inpatient versus outpatient management. Results Among COVID-19 adults, 1,360,078 patients were managed in an outpatient setting while 545,635 patients required hospitalization. Compared to hospitalized COVID-19 adults, COVID-19 adults who were managed in an outpatient setting were more likely to be female (56.1% vs 47.5%, p <0.001), white (57.7% vs 54.8%, p <0.001), within younger age group of 18–50 years (p<0.001) and have lower rate of comorbidities. Mortality was significantly lower in outpatient group compared to hospitalized group (0.2% vs 12.2%, respectively, p <0.01%). For outpatient group, mortality increased with increasing age group: 0.02% (52 of 295,112) for patients 18–30 years and 1.2% (1,373 of 117,866) for patients >75 years. The rate of hospitalization was lowest for age group 18–30 years at 10.6% (35,607 of 330,719) and highest for age group >75 years at 56.1% (150,381 of 268,247). Conclusion This analysis of US academic centers showed that 28.6% of COVID-19 adults who sought care at one of the hospitals reporting data to the Vizient clinical database required in-patient treatment. The rate of hospitalization in our study was lowest for the youngest age group of 18–30 years and highest for age group >75 years. Beside older age, other factors associated with outpatient management included female gender, white race, and having commercial insurance.

Abstract
INTRODUCTION Strategies are needed to increase implementation of evidence-based tobacco dependence treatment (TDT) in health care systems in low-and middle-income countries (LMICs). METHODS We conducted a two-arm cluster randomized controlled trial to compare the effectiveness of two strategies for implementing TDT guidelines in community health centers (n=26) in Vietnam. Arm 1 included training and a tool kit (e.g., reminder system) to promote and support delivery of the 4As (Ask about tobacco use, Advise to quit, Assess readiness, Assist with brief counseling) (Arm 1). Arm 2 included Arm 1 components plus a system to refer smokers to a community health worker (CHW) for more intensive counseling (4As+R). Provider surveys were conducted at baseline, six- and 12-months to assess the hypothesized effect of the strategies on provider and organizational-level factors. The primary outcome was provider adoption of the 4As. RESULTS Adoption of the 4As increased significantly across both study arms (all p<.001). Perceived organizational priority for TDT, compatibility with current workflow, and provider attitudes, norms and self-efficacy related to TDT also improved significantly across both arms. In Arm 2 sites, 41% of smokers were referred to a CHW for additional counseling. CONCLUSION The study demonstrated the effectiveness of a multicomponent and multilevel strategy (i.e., provider and system) for implementing evidence-based TDT in the Vietnam public health system. Combining provider-delivered brief counseling with opportunities for more in-depth counseling offered by a trained CHW may optimize outcomes and offers a potentially scalable model for increasing access to TDT in health care systems like Vietnam. IMPLICATIONS Improving implementation of evidence-based tobacco dependence treatment (TDT) guidelines is a necessary step towards reducing the growing burden of non-communicable disease (NCDs) and premature death in LMICs. The findings provide new evidence on the effectiveness of multilevel strategies for adapting and implementing TDT into routine care in Vietnam, and offers a potentially scalable model for meeting FCTC Article 14 goals in other LMICs with comparable public health systems. The study also demonstrates that combining provider-delivered brief counseling with referral to a community health worker for more in-depth counseling and support can optimize access to evidence-based treatment for tobacco use.

Abstract
IMPORTANCE Prior studies on COVID-19 and pregnancy have reported higher rates of cesarean delivery and preterm birth and increased morbidity and mortality. Additional data encompassing a longer time period are needed. OBJECTIVE To examine characteristics and outcomes of a large US cohort of women who underwent childbirth with vs without COVID-19. DESIGN, SETTING, AND PARTICIPANTS This cohort study compared characteristics and outcomes of women (age ≥18 years) who underwent childbirth with vs without COVID-19 between March 1, 2020, and February 28, 2021, at 499 US academic medical centers or community affiliates. Follow-up was limited to in-hospital course and discharge destination. Childbirth was defined by clinical classification software procedural codes of 134-137. A diagnosis of COVID-19 was identified using International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) diagnosis of U07.1. Data were analyzed from April 1 to April 30, 2021. EXPOSURES The presence of a COVID-19 diagnosis using ICD-10. MAIN OUTCOMES AND MEASURES Analyses compared demographic characteristics, gestational age, and comorbidities. The primary outcome was in-hospital mortality. Secondary outcomes included hospital length of stay, intensive care unit (ICU) admission, mechanical ventilation, and discharge status. Continuous variables were analyzed using t test, and categorical variables were analyzed using χ2. RESULTS Among 869 079 women, 18 715 (2.2%) had COVID-19, and 850 364 (97.8%) did not. Most women were aged 18 to 30 years (11 550 women with COVID-19 [61.7%]; 447 534 women without COVID-19 [52.6%]) and were White (8060 White women [43.1%] in the COVID-19 cohort; 499 501 White women (58.7%) in the non-COVID-19 cohort). There was no significant increase in cesarean delivery among women with COVID-19 (6088 women [32.5%] vs 273 810 women [32.3%]; P = .57). Women with COVID-19 were more likely to have preterm birth (3072 women [16.4%] vs 97 967 women [11.5%]; P < .001). Women giving birth with COVID-19, compared with women without COVID-19, had significantly higher rates of ICU admission (977 women [5.2%] vs 7943 women [0.9%]; odds ratio [OR], 5.84 [95% CI, 5.46-6.25]; P < .001), respiratory intubation and mechanical ventilation (275 women [1.5%] vs 884 women [0.1%]; OR, 14.33 [95% CI, 12.50-16.42]; P < .001), and in-hospital mortality (24 women [0.1%] vs 71 [<0.01%]; OR, 15.38 [95% CI, 9.68-24.43]; P < .001). CONCLUSIONS AND RELEVANCE This retrospective cohort study found that women with COVID-19 giving birth had higher rates of mortality, intubation, ICU admission, and preterm birth than women without COVID-19.

Abstract
Introduction The coronavirus disease 2019 (COVID-19) pandemic continues to be a global threat, with tremendous resources invested into identifying risk factors for severe COVID-19 illness. The objective of this study was to analyze the characteristics and outcomes of male compared to female adults with COVID-19 who required hospitalization within US academic centers. Methods Using the Vizient clinical database, discharge records of adults with a diagnosis of COVID-19 between March 1, 2020 and November 30, 2020 were reviewed. Outcome measures included demographics, characteristics, length of hospital stay, rate of respiratory intubation and mechanical ventilation, and rate of in-hospital mortality of male vs female according to age, race/ethnicity, and presence of preexisting comorbidities. Results Among adults with COVID-19, 161,206 were male while 146,804 were female. Adult males with COVID-19 were more likely to have hypertension (62.1% vs 59.6%, p <0.001%), diabetes (39.2% vs 36.0%, p <0.001%), renal failure (22.3% vs 18.1%, p <0.001%), congestive heart failure (15.3% vs 14.6%, p <0.001%), and liver disease (5.9% vs 4.5%, p <0.001%). Adult females with COVID-19 were more likely to be obese (32.3% vs 25.7%, p<0.001) and have chronic pulmonary disease (23.7% vs 18.1%, p <0.001). Gender was significantly different among races (p<0.001), and there was a lower proportion of males versus females in African American patients with COVID-19. Comparison in outcomes of male vs. female adults with COVID-19 is depicted in Table 2. Compared to females, males with COVID-19 had a higher rate of in-hospital mortality (13.8% vs 10.2%, respectively, p <0.001); a higher rate of respiratory intubation (21.4% vs 14.6%, p <0.001); and a longer length of hospital stay (9.5 ± 12.5 days vs. 7.8 ± 9.8 days, p<0.001). In-hospital mortality analyzed according to age groups, race/ethnicity, payers, and presence of preexisting comorbidities consistently showed higher death rate among males compared to females (Table 2). Adult males with COVID-19 were associated with higher odds of mortality compared to their female counterparts across all age groups, with the effect being most pronounced in the 18–30 age group (OR, 3.02 [95% CI, 2.41–3.78]). Conclusion This large analysis of 308,010 COVID-19 adults hospitalized at US academic centers showed that males have a higher rate of respiratory intubation and longer length of hospital stay compared to females and have a higher death rate even when compared across age groups, race/ethnicity, payers, and comorbidity.

Abstract
OBJECTIVE This study analyzed the outcomes of COVID-19 patients with ARDS who were managed with extracorporeal membrane oxygenation (ECMO) across 155 US academic centers. SUMMARY BACKGROUND DATA ECMO has been utilized in COVID-19 patients with acute respiratory distress syndrome (ARDS) and refractory hypoxemia. Early case series with the use of ECMO in these patients reported high mortality exceeding 90%. METHODS Using ICD-10 codes, data of patients with COVID-19 with ARDS, managed with ECMO between April and September 2020, were analyzed using the Vizient clinical database. Outcomes measured included in-hospital mortality, hospital and ICU length of stay, and direct cost. For comparative purposes, the outcome of a subset of COVID-19 patients aged between 18 and 64 years and managed with versus without ECMO were examined. RESULTS 1,182 patients with COVID-19 and ARDS received ECMO. In-hospital mortality was 45.9%, mean length of stay was 36.8 ± 24.9 days, and mean ICU stay was 29.1 ± 17.3 days. In-hospital mortality according to age group was 25.2% for 1 to 30 years; 42.2% for 31 to 50 years; 53.2% for 51 to 64 years; and 73.7% for ≥65 years. A subset analysis of COVID-19 patients, aged 18 to 64 years with ARDS requiring mechanical ventilation and managed with (n = 1113) vs without (n = 16,343) ECMO, showed relatively high in-hospital mortality for both groups (44.6% with ECMO vs 37.9% without ECMO). CONCLUSIONS In this large US study of patients with COVID-19 and ARDS managed with ECMO, the in-hospital mortality is high but much lower than initial reports. Future research is needed to evaluate which patients with COVID-19 and ARDS would benefit from ECMO.

[PMID: 34170950 PMCID: PMC8232521 DOI: 10.1371/journal.pone.0253767] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 06/12/2021] [Indexed: 12/15/2022] Open
Abstract
Background COVID-19’s pulmonary manifestations are broad, ranging from pneumonia with no supplemental oxygen requirements to acute respiratory distress syndrome (ARDS) with acute respiratory failure (ARF). In response, new oxygenation strategies and therapeutics have been developed, but their large-scale effects on outcomes in severe COVID-19 patients remain unknown. Therefore, we aimed to examine the trends in mortality, mechanical ventilation, and cost over the first six months of the pandemic for adult COVID-19 patients in the US who developed ARDS or ARF. Methods and findings The Vizient Clinical Data Base, a national database comprised of administrative, clinical, and financial data from academic medical centers, was queried for patients ≥ 18-years-old with COVID-19 and either ARDS or ARF admitted between 3/2020-8/2020. Demographics, mechanical ventilation, length of stay, total cost, mortality, and discharge status were collected. Mann-Kendall tests were used to assess for significant monotonic trends in total cost, mechanical ventilation, and mortality over time. Chi-square tests were used to compare mortality rates between March-May and June-August. 110,223 adult patients with COVID-19 ARDS or ARF were identified. Mean length of stay was 12.1±13.3 days and mean total cost was $35,991±32,496. Mechanical ventilation rates were 34.1% and in-hospital mortality was 22.5%. Mean cost trended downward over time (p = 0.02) from $55,275 (March) to $18,211 (August). Mechanical ventilation rates trended down (p<0.01) from 53.8% (March) to 20.3% (August). Overall mortality rates also decreased (p<0.01) from 28.4% (March) to 13.7% (August). Mortality rates in mechanically ventilated patients were similar over time (p = 0.45), but mortality in patients not requiring mechanical ventilation decreased from March-May compared to June-July (13.5% vs 4.6%, p<0.01). Conclusions This study describes the outcomes of a large cohort with COVID-19 ARDS or ARF and the subsequent decrease in cost, mechanical ventilation, and mortality over the first 6 months of the pandemic in the US.

Outcomes of Complex Gastrointestinal Cancer Resection at US News & World Report Top-Ranked vs Non-Ranked Hospitals. J Am Coll Surg 2021; 233:21-27.e1. [PMID: 33752982 DOI: 10.1016/j.jamcollsurg.2021.02.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Accepted: 02/02/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND The US News & World Report (USNWR) annual ranking of the best hospitals for gastroenterology and gastrointestinal surgery offers direction to patients and healthcare providers, especially for recommendations on complex medical and surgical gastrointestinal (GI) conditions. The objective of this study was to examine the outcomes of complex GI cancer resections performed at USNWR top-ranked, compared to non-ranked, hospitals. STUDY DESIGN Using the Vizient database, data for patients who underwent esophagectomy, gastrectomy, and pancreatectomy for malignancy between January and December 2018 were reviewed. Perioperative outcomes were analyzed according to USNWR rank status. Primary outcome was in-hospital mortality. Secondary outcomes include length of stay, mortality index (observed-to-expected mortality ratio), rate of serious complication, and cost. Secondary analysis was performed for outcomes of patients who developed serious complications. RESULTS There were 3,054 complex GI cancer resections performed at 42 top-ranked hospitals vs 3,608 resections performed at 198 non-ranked hospitals. The mean annual case volume was 73 cases at top-ranked hospitals compared to 18 cases at non-ranked hospitals. Compared with non-ranked hospitals, top-ranked hospitals had lower in-hospital mortality (0.96% vs 2.26%, respectively, p < 0.001) and lower mortality index (0.71 vs 1.53, respectively). There were no significant differences in length of stay, rate of serious complications, or direct cost between groups. In patients who developed serious morbidity, top-ranked hospitals had a lower mortality compared with non-ranked hospitals (8.2% vs 16.8%, respectively, p < 0.01). CONCLUSIONS Within the context of complex GI cancer resection, USNWR top-ranked hospitals performed a 4-fold higher case volume and were associated with improved outcomes. Patients with complex GI-related malignancies may benefit from seeking surgical care at high-volume regional USNWR top-ranked hospitals.

Collaboration between GI surgery & Gastroenterology improves understanding of the optimal antireflux valve-the omega flap valve. Surg Endosc 2021; 35:3214-3220. [PMID: 33709228 DOI: 10.1007/s00464-021-08416-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Accepted: 02/23/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a chronic and sometimes disabling disease. An important component in the surgical management of GERD is either laparoscopic or endoscopic restoration of the native gastroesophageal flap valve (GEFV). Recently, a procedure combining laparoscopic hiatal hernia repair with transoral incisionless fundoplication (cTIF) was introduced. This relatively new operation is performed in collaboration between the gastrointestinal (GI) surgeon and the gastroenterologist. METHODS By working together, both interventionalists gain new insight into the ideal GEFV by observing the same operation being performed from different perspectives. In the cTIF, the gastroenterologist learns from an external perspective, through the laparoscopic view, the importance of the crura in contributing to the antireflux barrier. Similarly, the GI surgeon gains understanding of the elements that define an effective and desirable GEFV through an endoscopic perspective. RESULTS This collaboration with cTIF and seeing the procedure from different perspectives have led to our improved understanding of 1) factors contributing to an optimal surgically constructed GEFV and 2) the limitations of the GEFV constructed by the conventional laparoscopic total and partial fundoplications. CONCLUSION The collaboration between GI surgery and gastroenterology with cTIF has led to an improved understanding in characteristics of an optimal antireflux barrier and allowed for a proposed technical modification of the current fundoplication technique to optimize the construct of the surgical GEFV.

Abstract
As the coronavirus disease 2019 pandemic continues to impact hospital systems both in the United States and throughout the world, it is important to understand how the pandemic has impacted the volume of hospital admissions. Using the Vizient Inc (Chicago, IL) clinical databases, we analyzed inpatient hospital discharges from the general medicine service and its subspecialty services including cardiology, neonatology, pulmonary/critical care, oncology, psychiatry, and neurology between December 2019 and July 2020. We compared baseline discharge data to that of the first six months of the pandemic, from February to July 2020. We set the baseline as discharges by specialty from February 2019 through January 2020, averaged over the 12 months. Compared to baseline, by April 2020 the volume of general medicine hospital discharge was reduced by -20.2%, from 235,581 to 188,027 discharges. We found that while overall the number of discharges decreased from baseline, with a nadir in April 2020, pulmonary/critical care services had an increase in hospital discharge volume throughout the pandemic, from 7534 at baseline to 15,792 discharges in April. These findings are important for understanding health care use during the pandemic and ensuring proper allocation of resources and funding throughout the coronavirus disease 2019 pandemic.

Novel Interdisciplinary Approach to GERD: Concomitant Laparoscopic Hiatal Hernia Repair with Transoral Incisionless Fundoplication. J Am Coll Surg 2020; 232:309-318. [PMID: 33346082 DOI: 10.1016/j.jamcollsurg.2020.11.021] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 11/21/2020] [Accepted: 11/23/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Transoral incisionless fundoplication (TIF) is an endoscopic alternative for the treatment of GERD. However, TIF does not address the hiatal hernia (HH). We present a novel approach with a laparoscopic HH repair followed by same-session TIF, coined concomitant transoral incisionless fundoplication (cTIF). The aim of this study was to assess the efficacy, safety, and feasibility of cTIF in a collaborative approach between Gastroenterology and surgery. STUDY DESIGN Patients with confirmed GERD and >2 cm HH who underwent cTIF between 2018 and 2020 were included. Symptoms were assessed using the Reflux Disease Questionnaire, GERD Health-Related Quality of Life Index, and the Reflux Symptom Index pre and post cTIF. One-way ANOVA and paired samples t-test were used for statistical analysis. RESULTS Sixty patients underwent cTIF (53% were men, mean age was 59.3 years) with 100% technical success. Mean ± SD HH measurement on endoscopy was 2.9 ± 1.5 cm. Scores on Reflux Disease Questionnaire for symptom frequency and symptom severity improved significantly from before to 6 months after cTIF (17.4 to 4.72; p < 0.01 and 16.7 to 4.56; p < 0.05, respectively). According to the GERD Health-Related Quality of Life Index, significant decreases were seen post cTIF in heartburn (23.26 to 7.37; p < 0.01) and regurgitation (14.26 to 0; p = 0.05). Reflux Symptom Index similarly decreased after cTIF (17.7 to 8.1 post cTIF; p < 0.01). Mean DeMeester score decreased from 43.7 to 4.9 and acid exposure time decreased from 12.7% to 1.28% post cTIF (p = 0.06). CONCLUSIONS We present a novel multidisciplinary approach to GERD using a combined endoscopic and surgical approach with close collaboration between Gastroenterology and surgery. Our results suggest that cTIF is safe and effective in reducing reflux symptoms in a large spectrum of GERD patients.

Abstract
BACKGROUND Appendiceal cancer (AC) is a rare malignancy usually diagnosed incidentally after appendectomy. Risk factors for AC are poorly understood. We sought to provide a descriptive analysis for patients with AC discovered after appendectomy for acute appendicitis (AA). METHODS The 2016-2017 American College of Surgeons-National Surgical Quality Improvement Program Procedure-Targeted Appendectomy database was queried for adult patients who underwent appendectomy for image-suspected AA. Patients with pathology consistent with AA were compared to patients found to have AC. A multivariable logistic regression model was used for analysis. RESULTS From 21 058 patients, 203 (1.0%) were found to have AC on pathology. Compared to patients with AA, patients with AC were older (median, 48 vs. 40 years old, P < .001). The AA group had a similar rate of perforated appendix compared to the AC group (16.3% vs. 13.4% P = .32). After adjusting for covariates, associated risk factors for AC were: age ≥65 years old (odds ratio (OR) 2.25, 1.5-3.38, P < .001), absence of leukocytosis (OR 1.58, 1.16-2.17, P = .004), and operative time ≥1 hour (OR 1.57, 1.14-2.16, P = .006). Gender, race, and history of smoking were not independent associated risk factors for AC. CONCLUSION The incidence of AC after appendectomy for suspected AA is approximately 1% in a large national analysis. These factors may be used to help identify patients at higher risk for AC after appendectomy.

Abstract
BACKGROUND The impact of preoperative chemotherapy/radiation on esophageal anastomotic leaks (ALs) and the correlation between AL severity and mortality risk have not been fully elucidated. We hypothesized that lower severity ALs have a similar risk of mortality compared to those without ALs, and preoperative chemotherapy/radiation increases AL risk. METHODS The 2016-2017 American College of Surgeons National Surgical Quality Improvement Program's procedure-targeted esophagectomy database was queried for patients undergoing any esophagectomy for cancer. A multivariable logistic regression analysis was performed for risk of ALs. RESULTS From 2042 patients, 280 (13.7%) had ALs. AL patients requiring intervention had increased mortality risk including those requiring reoperation, interventional procedure, and medical therapy (P < .05). AL patients requiring no intervention had similar mortality risk compared to patients without ALs (P > .05). Preoperative chemotherapy/radiation was not predictive of ALs (P > .05). CONCLUSION Preoperative chemotherapy/radiation does not contribute to risk for ALs after esophagectomy. There is a stepwise increased risk of 30-day mortality for ALs requiring increased invasiveness of treatment.

Abstract
Colistin is one of the antibiotics of last resort for human health. However, the dissemination of the plasmid-mediated colistin resistance gene mcr-1 is of great concern globally. In the One Health framework, the environment is an important component for managing antimicrobial resistance. However, little information is available concerning the prevalence of mcr-1 in water environments. We aimed to reveal the prevalence of mcr-1 in different water environments in Hanoi, Vietnam. Quantitative PCR was applied to detect mcr-1 in four urban drainages receiving untreated domestic wastewater, three rivers, five lakes and two groundwater samples. Urban drainages contained higher concentrations of mcr-1, suggesting that urban residents carry the gene. The class 1 integron-integrase gene was identified as a good surrogate of antibiotic resistance genes including mcr-1. A significant correlation was found between the levels of mcr-1 and the human-specific cross-assembly phage, which is an indicator of human faecal pollution. These results indicated that the primary source of mcr-1 in urban water environments is human faeces, which is consistent with the fact that most domestic wastewater is untreated in Hanoi. The control of untreated wastewater is critical for alleviating the spread of mcr-1 in water environments in Vietnam.

Abstract
INTRODUCTION Anastomotic leak is a dreaded complication following esophagectomy. Conventional management for leaks includes invasive reoperation and even gastrointestinal diversion. OBJECTIVE The aim of this study was to examine our contemporary outcome of using endoscopic esophageal stenting as primary therapy for management of anastomotic leak following minimally invasive esophagectomy (MIE). METHODS We reviewed data on 11 patients who developed an esophageal leak following 111 MIE between January 2011 and December 2019. Of the 11 anastomotic leaks, 10 patients had an anastomotic disruption and underwent endoscopic esophageal stenting as primary therapy for management of leaks, while 1 patient had an anastomotic disruption complicated by an associated tracheoesophageal fistula that required surgical reoperation and subsequent colonic interposition. Main outcome measures focused on the 10 patients who were managed with endoscopic stenting, including length of hospital stay following leak management, need for thoracotomy or gastrointestinal diversion for leak, stent complications, and leak-associated mortality. RESULTS Of the 10 patients who underwent endoscopic esophageal stenting as primary therapy for management of leaks, there were 8 males with a median age of 66 years. The median time to diagnosis of anastomotic leak was 10 days postoperatively. One of the ten patients also underwent percutaneous drain placement, while none of the patients required thoracotomy. Median duration of stent placement was 39 (range, 29-105) days. Median length of stay after stent placement was 10 (range, 4-43) days. The median number of stent exchange was 1 (range, 1-3) stent. Gastrointestinal continuity was maintained in all patients. The 90-day leak-associated mortality was 9.1% (1 of 11 patients). CONCLUSIONS Endoscopic stenting is an effective primary therapy in the management of postesophagectomy leak and avoids the need for an invasive, reoperative thoracotomy or gastrointestinal diversion procedure.

Abstract
BACKGROUND Isolated diaphragm injury (IDI) occurs in up to 30% of penetrating left thoracoabdominal injuries. Laparoscopic abdominal procedures have demonstrated improved outcome including decreased postoperative pain and length of stay (LOS) compared to open surgery. However, there is a paucity of data on this topic for penetrating IDI. The aim of this study was to examine the prevalence and outcome of laparoscopic diaphragmatic repair versus open diaphragmatic repair (LDR vs ODR) of IDI. METHODS The Trauma Quality Improvement Program (2010-2016) was queried for patients with IDI who underwent ODR versus LDR. A bivariate analysis using Pearson chi-square and Mann-Whitney test was performed to determine LOS among the two groups. RESULTS From 2039 diaphragm injuries, 368 patients had IDI; 281 patients (76.4%) underwent ODR and 87 (23.6%) underwent LDR. Compared to LDR, the ODR patients were older (median, 31 vs 25 years, P < .001) and had a higher injury severity score (mean, 11.2 vs 9.6, P = .03) but had similar rates of intensive care unit LOS, unplanned return to the operating room, ventilator days, and complications (P > .05). Patients undergoing ODR had a longer LOS (5 vs 4 days, P = .01), compared to LDR. There were no deaths in either group. CONCLUSIONS Trauma patients presenting with IDI undergoing ODR had a longer hospital LOS compared to patients undergoing LDR with no difference in complications or mortality. Therefore, we recommend when possible an LDR should be employed to decrease hospital LOS. Further research is needed to examine other benefits of laparoscopy such as postoperative pain, incisional hernia, and wound-related complications.

Abstract
Importance The US News & World Report (USNWR) annual ranking of the best hospitals for gastroenterology and gastrointestinal operations provides guidance and referral of care for medical and surgical gastrointestinal conditions. Objective To investigate whether USNWR top-ranked hospitals for gastroenterology and gastrointestinal surgical procedures are associated with improvements in patient outcomes, compared with nonranked hospitals, in common advanced laparoscopic abdominal operations. Design, Setting, and Participants This study used the Vizient database, which contains administrative, clinical, and financial inpatient information of index hospitalizations for US academic centers and their affiliated hospitals that are members of Vizient. Data were obtained on advanced laparoscopic abdominal operations performed from January 1, 2017, through December 31, 2017, at USNWR top-ranked hospitals (n = 16 296 operations) and nonranked hospitals (n = 35 573 operations). Abdominal operations included bariatric, colorectal, and hiatal hernia procedures. Operations on patients younger than 18 years, emergent cases, conversion cases, and patients with extreme severity of illness were excluded. Main Outcomes and Measures Outcome measures included in-hospital mortality, mortality index (observed to expected mortality ratio), serious morbidity, length of stay, and cost. Results A total of 51 869 advanced laparoscopic abdominal operations were performed at 351 academic health centers and their community affiliates. Of these procedures, 16 296 (31.4%) were performed at 41 top-ranked hospitals and 35 573 (68.6%) at 310 nonranked hospitals. The annual case volume at top-ranked hospitals was 397 compared with 114 at nonranked hospitals. Between top-ranked and nonranked hospitals, no significant differences were found in in-hospital mortality (0.04% vs 0.07%; P = .33) or serious morbidity (1.06% vs 1.02%; P = .75). Compared with nonranked hospitals, advanced laparoscopic abdominal operations performed at top-ranked hospitals had higher mean costs ($7128 [$4917] vs $7742 [$6787]; P < .01) and longer mean lengths of stay (2.38 [2.60] days vs 2.73 [3.31] days; P < .01). Conclusions and Relevance Although, among academic centers, the annual volume of advanced laparoscopic abdominal operations was 3-fold higher for USNWR top-ranked hospitals compared with nonranked hospitals, the volume did not appear to be associated with improved patient outcomes.

Abstract
Acute respiratory failure (ARespF) is a common complication after esophagectomy that contributes to higher morbidity and mortality. Using the Nationwide Inpatient Sample database, we sought to identify predictors of ARespF in 6352 patients who underwent esophagectomy for malignancy between 2006 and 2008. Multivariate regression analyses were performed to identify preoperative factors (patient characteristics, comorbidities, procedural type, tumor's location, hospital teaching status, and payer type) predictive of ARespF in esophagectomy. The overall rate of ARespF was 27.08 per cent. For comorbidities, independent risk factors for higher rate of ARF included weight loss (adjusted odds ratio [AOR], 3.63; 95% confidence interval [CI], 3.02 to 4.37), pulmonary hypertension (AOR, 2.38; 95% CI, 1.85 to 3.45), congestive heart failure (AOR, 2.35; 95% CI, 1.77 to 3.13), liver disease (AOR, 1.95; 95% CI, 1.22 to 3.12), chronic lung disease (AOR, 1.40; 95% CI, 1.17 to 1.66), and anemia (AOR, 1.26; 95% CI, 1.04 to 1.51). Cervical location of malignancy (AOR, 2.32; 95% CI, 1.51 to 3.56), total esophagectomy (AOR, 1.64; 95% CI, 1.41 to 1.90), and non-teaching hospital (AOR, 1.45; 95% CI, 1.20 to 1.75) were independent risk factors for ARespF. There was no effect of age, gender, race, hypertension, diabetes, renal failure, obesity, smoking, peripheral vascular disorder, or payer type on ARespF. We identified multiple preoperative risk factors that have an impact on development of ARespF after esophagectomy. Surgeons can use these factors to inform patients of potential risks and should consider these factors during surgical-decision making.

Abstract
In patients undergoing bariatric surgery, the presence of metabolic syndrome (MetS) contributes to perioperative morbidity. We aimed to evaluate the utilization and outcome of severely obese patients with MetS who underwent laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB). Using the 2015 and 2016 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, data were obtained for patients with MetS undergoing LSG or LRYGB. There were 29,588 MetS patients (LSG: 58.7% vs LRYGB: 41.3%). There was no significant difference in 30-day mortality (0.1% for LSG vs 0.2% for LRYGB, adjusted odds ratio (AOR) 0.58, confidence interval (CI) 0.32–1.05, P = 0.07) or length of stay between groups (2 ± 2 for LSG vs 2.2 ± 2 days for LRYGB, P = 0.40). Compared with LRYGB, LSG was associated with significantly shorter operative time (78 ± 39 vs 122 ± 54 minutes, P < 0.01), lower overall morbidity (2.3% vs 4.4%, AOR 0.53, CI 0.46–0.60, P < 0.01), lower serious morbidity (1.5% vs 2.3%, AOR 0.64, CI 0.53–0.76, P < 0.01), lower 30-day reoperation (1.2% vs 2.3%, AOR 0.52, CI 0.43–0.63, P < 0.01), and lower 30-day readmission (4.2% vs 6.6%, AOR 0.62, CI 0.55–0.69, P < 0.01). In conclusion, LSG is the predominant operation being performed for severely obese patients with MetS, and its popularity may in part be related to its improved perioperative safety profile.

The effect of transparency on the gender-based compensation gap in surgical disciplines within a large academic healthcare system. Surg Endosc 2020; 35:2607-2612. [PMID: 32488656 DOI: 10.1007/s00464-020-07679-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Accepted: 05/27/2020] [Indexed: 11/27/2022]
Abstract
BACKGROUND Female representation in surgery and surgical subspecialties has increased over the last decade. Studies have shown a discrepancy in compensation in the field of surgery, and several groups have advocated for increasing transparency as a primary solution to decrease this gender salary gap in surgery. The aim of this study was to evaluate differences in compensation between genders in surgical specialties within a large academic healthcare system. METHODS Using a public compensation database from January 1, 2016 through December 31, 2016, this retrospective observational study analyzed salaries of full-time faculty surgeons within a large multi-institutional academic healthcare system. Surgeons included those who were employed for the entirety of 2016 and were full-time faculty who were then stratified according to surgical specialty and rank. The median base and median total salaries were compared between male and female surgeons with adjustment for rank and surgical specialty. RESULTS There were 170 surgeons from eight surgical subspecialties included in the study with 29% being female (n = 50). Overall, unadjusted and adjusted median total salaries were significantly lower for female compared to male surgeons by $121,578 and $45,904, respectively. The three subspecialties with the highest compensation had a median total salary of $558,998 and had a high male to female ratio (3.7 male to 1 female), whereas the three subspecialties with the lowest compensation had a median total salary of $376,174 and had a male to female ratio of 1.5 male to 1 female. CONCLUSIONS In a large academic healthcare system with transparent and publicly accessible salaries, the gender compensation gap in surgery persists. In conjunction with transparency, future academic institutions should consider a value-based, objective compensation plan with personal and systemic introspection of traditional gender biases, in efforts to circumvent the impact of gender on salary.

Geriatric patients undergoing appendectomy have increased risk of intraoperative perforation and/or abscess. Surgery 2020; 168:322-327. [PMID: 32461001 DOI: 10.1016/j.surg.2020.04.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Revised: 04/08/2020] [Accepted: 04/15/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND The number of geriatric patients is expected to grow 3-fold over the next 30 years, and as many as 50% of the surgeries done in the United States may occur in geriatric patients. Geriatric patients often have increased comorbidities and more often present in a delayed manner for acute appendicitis. The aim of this study was to evaluate outcomes between geriatric patients and younger patients undergoing appendectomy, hypothesizing that geriatric patients will have a higher risk of abscess and/or perforation, conversion to open surgery, postoperative intra-abdominal abscess, and 30-day readmission. METHODS The 2016 to 2017 American College of Surgeons National Surgical Quality Improvement Program Procedure Targeted Appendectomy database was queried for patients with preoperative image findings consistent with acute appendicitis. Geriatric patients (age ≥65 years old) were compared with younger patients (age <65 years old). A multivariable logistic regression model was used for analysis. RESULTS From 21,586 patients undergoing appendectomy, 2,060 (9.5%) were geriatric patients. Compared with the younger cohort, geriatric patients were less likely to have leukocytosis (59.0% vs 65.8%, P < .001) and more likely to have a tumor and/or malignancy involving the appendix on final pathology (2.0% vs 0.8%, P < .001), an unplanned laparoscopic conversion to open surgery (4.2% vs 1.5%, P < .001), and 30-day readmission (7.0% vs 3.3%, P < .001). Geriatric patients had a longer median length of stay (2 vs 1 days, P < .001) and higher mortality rate (0.5% vs <0.1%, P < .001). After adjusting for covariates, there was an increased associated risk of intraoperative abscess and/or perforation (odds ratio 2.23, 2.01-2.48, P < .001) and postoperative intra-abdominal abscess (odds ratio 1.43, 1.12-1.83, P = .005) but no difference in associated risk for mortality (odds ratio 2.56, 0.79-8.25, P = .116), compared with the younger cohort. CONCLUSION Nearly 10% of laparoscopic appendectomies are done on geriatric patients with geriatric patients having a higher rate of conversion to open surgery and tumor and/or malignancy on final pathology. Geriatric patients have an associated increased risk of intraoperative perforation and/or abscess and postoperative intra-abdominal abscess but have similar risk for mortality compared with nongeriatric patients undergoing laparoscopic appendectomy.

Short- and long-term survival after laparoscopic versus open total gastrectomy for gastric adenocarcinoma: a National database study. Surg Endosc 2020; 35:1872-1878. [PMID: 32394166 DOI: 10.1007/s00464-020-07591-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2019] [Accepted: 04/22/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND The use of laparoscopic total gastrectomy for gastric cancer remains controversial. Our objective was to compare outcomes of laparoscopic total gastrectomy (LTG) vs. open total gastrectomy (OTG) for gastric adenocarcinoma using a national cancer database. METHODS The National Cancer Database (2010-2014) was analyzed for total gastrectomy cases performed for gastric adenocarcinoma. Patient demographics and surgical outcomes were stratified by stage and compared based on laparoscopic vs. open surgical approach. Primary outcome measures included 30-day and 90-day mortality and Kaplan-Meier curves to estimate long-term survival. RESULTS There were 2584 cases analyzed, including 592 (22.9%) stage I, 710 (27.5%) stage II, and 1282 (49.6%) stage III cases. The distribution of LTG vs. OTG cases was 156 (26.4%) vs. 436 (73.6%) for stage I, 163 (23.0%) vs. 547 (77.0%) for stage II, and 241 (18.8%) vs. 1041 (81.2%) for stage III. For all stages analyzed, there was no difference between laparoscopic vs. open approach for adjusted 30-day mortality (stage I: adjusted odds ratio (AOR) 0.52, p = 0.75; stage II: AOR 1.36, p > 0.99; stage III: AOR 0.46, p = 0.29) or 90-day mortality (stage I: AOR 0.46, p = 0.99; stage II: AOR 1.17, p = 0.99; stage III: 0.57, p = 0.29). There was no difference between LTG vs. OTG 5-year Kaplan-Meier estimated survival curves for any stage (stage I: p = 0.20; stage II: p = 0.83; stage III: p = 0.46). When compared to OTG, LTG had a similar hazard ratio (HR) for mortality (HR 0.89 p = 0.20). CONCLUSIONS Laparoscopic total gastrectomy and OTG have comparable 30-day mortality, 90-day mortality, and long-term survival.

High and low estimated glomerular filtration rates are associated with adverse outcomes in patients undergoing surgery for gastrointestinal malignancies. Nephrol Dial Transplant 2020; 34:810-818. [PMID: 29718365 DOI: 10.1093/ndt/gfy108] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2017] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Abnormally high estimated glomerular filtration rates (eGFRs) are associated with endothelial dysfunction and frailty. Previous studies have shown that low eGFR is associated with increased morbidity, but few reports address high eGFR. The purpose of this study is to evaluate the association of high eGFR with surgical outcomes in patients undergoing surgery for gastrointestinal malignancies. METHODS We identified patients who underwent elective surgery for gastrointestinal malignancies from 2005 to 2015 in the American College of Surgeons National Surgical Quality Improvement Program database. We evaluated associations of eGFR with surgical outcomes by Cox or logistic models with restricted cubic spline functions, adjusting for case mix variables (i.e. age, gender, race and diabetes). RESULTS The median eGFR is 83 (interquartile range 67-96) mL/min/1.73 m2. Thirty-day mortality was 1.9% (2555/136 896). There is a U-shaped relationship between eGFR and 30-day mortality. The adjusted hazard ratios (95% confidence intervals) for eGFRs of 30, 60, 105 and 120 mL/min/1.73 m2 (versus 90 mL/min/1.73 m2) are 1.73 (1.52-1.97), 1.00 (0.89-1.11), 1.42 (1.31-1.55) and 2.20 (1.79-2.70), respectively. Similar associations are shown for other surgical outcomes, including return to the operating room and postoperative pneumonia. Subgroup analyses show that eGFRs both higher and lower than the respective medians are consistently associated with a higher risk of adverse outcomes across age, gender and race. CONCLUSIONS High and low eGFRs are associated with more adverse surgical outcomes in patients undergoing surgery for gastrointestinal malignancies. The eGFR associated with the lowest postoperative risk is approximately at the median eGFR of a given population.

Abstract
BACKGROUND Cryopreservation of zona pellucida (ZP)-free embryos provides more options for somatic cell nuclear transfer, particularly during handmade cloning. OBJECTIVE This study investigated whether the removal of the ZP affects the development of porcine zygotes after vitrification and warming. MATERIALS AND METHODS We determined the appropriate volume of the corresponding medium for the individual culture of ZP-intact and -free embryos and evaluated the protection effect of ZP during cryopreservation on the resulting development of the vitrified-warmed zygotes. RESULTS The volume of culture medium influenced the development of ZP-intact zygotes, and a volume of 15 µL was most suitable for their development. However, the volume of culture medium did not modify the development of ZP-free zygotes. The removal of the ZP before vitrification did not adversely affect embryonic development or quality of the resulting blastocysts. CONCLUSION Our results suggest that the removal of the ZP does not cause detrimental effects to the development of vitrified-warmed zygotes.

Clinical and histopathological characterization of paradoxical head and neck erythema in patients with atopic dermatitis treated with dupilumab: a case series. Br J Dermatol 2019; 183:745-749. [PMID: 31749159 PMCID: PMC7586932 DOI: 10.1111/bjd.18730] [Citation(s) in RCA: 65] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/18/2019] [Indexed: 12/29/2022]
Abstract
Dupilumab is the first biologic registered for the treatment of atopic dermatitis (AD). We report on seven patients with AD presenting with a paradoxical head and neck erythema that appeared 10-39 weeks after the start of dupilumab treatment. The patients presented with a relatively sharply demarcated, patchy erythema in the head and neck area that showed no or less scaling compared with their usual eczema. Only one patient experienced symptoms of itch and burning, although this was notably different from his pre-existent facial AD. Except for a notable 'red face', eczema on other body parts had greatly improved in six of the seven patients, with a mean numerical rating scale for treatment satisfaction of 9 out of 10 at the time of biopsy. Treatment of the erythema with topical and systemic drugs was unsuccessful. Despite the presence of this erythema, none of our patients discontinued dupilumab treatment. Lesional skin biopsies showed an increased number of ectatic capillaries, and a perivascular lymphohistiocytic infiltration in all patients. In addition, epidermal hyperplasia with elongation of the rete ridges was observed in four patients, resembling a psoriasiform dermatitis. Additional immunohistochemical stainings revealed increased numbers of plasma cells, histiocytes and T lymphocytes. Interestingly, spongiosis was largely absent in all biopsies. We report on patients with AD treated with dupilumab developing a paradoxical erythema in a head and neck distribution. Both clinically and histopathologically we found a heterogeneous response, which was most suggestive of a drug-induced skin reaction.

Abstract
In patients undergoing bariatric surgery, the presence of metabolic syndrome (MetS) contributes to perioperative morbidity. We aimed to evaluate the utilization and outcome of severely obese patients with MetS who underwent laparoscopic sleeve gastrectomy (LSG) versus laparoscopic Roux-en-Y gastric bypass (LRYGB). Using the 2015 and 2016 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, data were obtained for patients with MetS undergoing LSG or LRYGB. There were 29,588 MetS patients (LSG: 58.7% vs LRYGB: 41.3%). There was no significant difference in 30-day mortality (0.1% for LSG vs 0.2% for LRYGB, adjusted odds ratio (AOR) 0.58, confidence interval (CI) 0.32-1.05, P = 0.07) or length of stay between groups (2 ± 2 for LSG vs 2.2 ± 2 days for LRYGB, P = 0.40). Compared with LRYGB, LSG was associated with significantly shorter operative time (78 ± 39 vs 122 ± 54 minutes, P < 0.01), lower overall morbidity (2.3% vs 4.4%, AOR 0.53, CI 0.46-0.60, P < 0.01), lower serious morbidity (1.5% vs 2.3%, AOR 0.64, CI 0.53-0.76, P < 0.01), lower 30-day reoperation (1.2% vs 2.3%, AOR 0.52, CI 0.43-0.63, P < 0.01), and lower 30-day readmission (4.2% vs 6.6%, AOR 0.62, CI 0.55-0.69, P < 0.01). In conclusion, LSG is the predominant operation being performed for severely obese patients with MetS, and its popularity may in part be related to its improved perioperative safety profile.
