Large Single-center Experience with Long-term Outcomes of EUS-guided Transmural Gallbladder Drainage.

GOALS: To describe the long-term outcomes of patients after EUS-guided gallbladder drainage (EUS-GBD), including those who underwent standardized stent exchanges for permanent plastic stents. BACKGROUND: EUS-GBD has become one of the first-line alternatives for gallbladder decompression, with outcomes and safety profiles comparable to that of percutaneous gallbladder drainage. However, the long-term outcomes of EUS-GBD are not well-described. We report our single-center experience of a large cohort who underwent EUS-GBD. STUDY: Patients who underwent EUS-GBD from August 2014 to December 2022 were included in the study. Patient demographics, comorbidities, and procedure details were recorded. Patients were followed until complete stent removal, end of study period, or death. Short and long-term outcomes include technical and clinical success, stent patency, recurrent cholecystitis, cholecystectomy, and death. RESULTS: During the study period, 128 patients were included. One hundred and one patients had benign indications for EUS-GBD, including cholecystitis and choledocholithiasis. Of those with malignant indications, 23 of 27 had distal malignant biliary obstruction. Technical and clinical successes were 95.3% and 95.1%, respectively. Stents were exchanged for 2 permanent double pigtail plastic stents in 43.0%. The mean stent patency was 421 days (488 d among those still alive) without any recurrent cholecystitis. CONCLUSION: EUS-GBD demonstrates prolonged stent patency and minimal long-term adverse events, particularly among patients who underwent stent exchanges for permanent plastic stents. EUS-GBD is also promising for patients presenting with choledocholithiasis and biliary colic who are not surgical candidates.

Abnormal bolus reflux on impedance-pH testing independently predicts 3-year pulmonary outcome and mortality in pulmonary fibrosis.

BACKGROUND AND AIM: Gastroesophageal reflux has been associated with idiopathic pulmonary fibrosis (IPF), although the directionality of the relationship has been debated. Data on the value of objective reflux measures in predicting IPF disease progression and mortality remain limited. We aimed to evaluate the association between multichannel intraluminal impedance and pH testing (MII-pH) and 3-year pulmonary outcomes in IPF patients. METHODS: This was a retrospective cohort study of adults with IPF who underwent pre-lung transplant MII-pH off acid suppression at a tertiary center. Patients were followed for 3 years after MII-pH for poor pulmonary outcomes (hospitalization for respiratory exacerbation or death). A secondary analysis was performed using mortality as outcome of interest. Time-to-event analyses using Kaplan-Meier and Cox regression were performed to evaluate associations between MII-pH and poor outcomes. RESULTS: One hundred twenty-four subjects (mean age = 61.7 ± 8 years, 62% male) were included. Increased bolus exposure time (BET) on MII-pH was associated with decreased time to poor pulmonary outcomes and death (log-ranked P-value = 0.017 and 0.031, respectively). On multivariable Cox regression analyses controlling for potential confounders including age, sex, smoking history, body mass index, proton pump inhibitor use, baseline pulmonary function, and anti-fibrotic therapy, increased BET was an independent predictor for poor pulmonary outcomes [hazard ratio 3.18 (95% confidence interval: 1.25-8.09), P = 0.015] and mortality [hazard ratio 11.3 (95% confidence interval: 1.37-63.9), P = 0.025] over 3 years. CONCLUSIONS: Increased BET on MII-pH is an independent predictor of poor pulmonary outcomes and mortality over 3 years in IPF patients. These findings also support a role for gastroesophageal reflux in IPF disease progression and the potential impact of routine reflux testing and treatment.

Failed Swallows on High-Resolution Manometry Independently Correlates With Severity of LPR Symptoms.

BACKGROUND: Abnormal esophageal motility is prevalent in gastroesophageal reflux disease patients; however, its relationship with laryngopharyngeal reflux (LPR) symptom severity remains unclear. Altered esophageal transit may contribute to LPR symptoms. We aimed to examine the relationship between reflux symptom index (RSI), a validated questionnaire for LPR symptoms, and abnormal esophageal motility on high-resolution manometry (HRM). METHODS: A total of 133 consecutive patients (55.9 ± 14.6 years, 69.9% female) with suspected LPR referred for HRM and multichannel intraluminal impedance-pH study (MII-pH) at a tertiary center from March 2015 to October 2017 were included. RSI questionnaire was prospectively collected prior to motility testing. Authors analyzing HRM and MII-pH were blinded to RSI findings. Statistical analyses were performed using Student's t test or Pearson's correlation (univariate) and general linear regression (multivariable). RESULTS: Mean RSI was higher among patients with ineffective esophageal motility than those with normal motility (23.7 vs 18.6, P = 0.01). Significant positive correlation was found between RSI and percent failed swallows (R2 = 0.21, P = 0.03), but not percent weak swallows. On multivariable analysis, percent ineffective (failed or weak) swallows was significantly associated with RSI (ß-coefficient: 0.072, P = 0.05) after controlling for age, gender, BMI, smoking, prior PPI use, and reflux on MII-pH. When analyzed separately, percent failed swallows (ß-coefficient: 0.095, P= 0.02), but not percent weak swallows, independently predicted higher RSI. CONCLUSIONS: Ineffective swallows, particularly failed swallows, are independently associated with higher RSI in patients with suspected LPR, even after controlling for reflux on MII-pH. Esophageal dysmotility may play a role in suspected LPR symptoms independent of reflux. HRM should be routinely considered in evaluating these patients.

Endoscopic ultrasound-guided biliary drainage in benign biliary pathology with normal foregut anatomy: a multicenter study.

BACKGROUND AND AIMS: Biliary drainage using endoscopic ultrasound (EUS-BD) has been developed as a novel technique to obtain biliary access and drainage when ERCP fails. Numerous studies have demonstrated its safety and efficacy specifically pertaining to those with malignant distal biliary obstruction or altered foregut anatomy. The aim of this study is to evaluate the safety and efficacy of EUS-BD in benign indications in patients with normal foregut anatomy. METHODS: We performed a retrospective comparative study from 5 academic medical centers (2008-2018) involving patients with benign biliary obstruction and native foregut anatomy who had an initial failed ERCP with subsequent attempt at biliary decompression via EUS-BD or by repeating ERCP. RESULTS: 36 patients (mean age 61.6 ± 2.2, 38.9% female) who underwent attempted EUS-BD following initial failed ERCP were compared to 50 patients (mean age 62.7 ± 2.3, 73.5% female) who underwent repeat ERCP following an initial failed cannulation. EUS-BD was technically successful in 28 (77.8%) patients with rendezvous being the most common approach (86.1%). A higher level of pre-procedural bilirubin was found to be associated with technical success of EUS-BD (3.65 ± 0.63 versus 1.1 ± 0.4, p value 0.04). Success of repeat ERCP following failed cannulation was 86%. Adverse events were significantly more frequent in the EUS-BD cohort when compared to the repeat ERCP (10 (27.8%) versus 4 (8.0%), p = 0.02, OR 4.32. CONCLUSIONS: EUS-BD remains a viable therapeutic option in the setting of benign biliary disease, with success rates of 77.8%. Adverse events were significantly more common with EUS-BD vs. repeat ERCP, emphasizing the need to perform in expert centers with appropriate multidisciplinary support and to strongly consider the urgency of biliary decompression before considering same session EUS-BD after failed initial biliary access.

Evaluation of socioeconomic and healthcare disparities on same admission cholecystectomy after endoscopic retrograde cholangiopancreatography among patients with acute gallstone pancreatitis.

BACKGROUND: Despite literature and guidelines recommending same admission cholecystectomy (CCY) after endoscopic retrograde cholangiopancreatography (ERCP) for patients with acute gallstone pancreatitis, clinical practice remains variable. The aim of this study was to investigate the role of clinical and socio-demographic factors in the management of acute gallstone pancreatitis. METHODS: Patients with acute gallstone pancreatitis who underwent ERCP during hospitalization were reviewed from the U.S. Nationwide Inpatient Sample database between 2008 and 2014. Patients were classified by treatment strategy: ERCP + same admission CCY (ERCP + CCY) versus ERCP alone. Measured variables including age, race/ethnicity, Charlson Comorbidity Index (CCI), hospital type/region, insurance payer, household income, length of hospital stay (LOS), hospitalization cost, and in-hospital mortality were compared between cohorts using χ2 and ANOVA. Multivariable logistic regression was performed to identify specific predictors of same admission CCY. RESULTS: A total of 205,012 patients (ERCP + CCY: n = 118,318 versus ERCP alone: n = 86,694) were analyzed. A majority (53.4%) of patients that did not receive same admission CCY were at urban-teaching hospitals. LOS was longer with higher associated costs for patients with same admission CCY [(6.8 ± 5.6 versus 6.4 ± 6.5 days; P < 0.001) and ($69,135 ± 65,913 versus $52,739 ± 66,681; P < 0.001)]. Mortality was decreased significantly for patients who underwent ERCP + CCY versus ERCP alone (0.4% vs 1.1%; P < 0.001). Multivariable regression demonstrated female gender, Black race, higher CCI, Medicare payer status, urban-teaching hospital location, and household income decreased the odds of undergoing same admission CCY + ERCP (all P < 0.001). CONCLUSION: Based upon this analysis, multiple socioeconomic and healthcare-related disparities influenced the surgical management of acute gallstone pancreatitis. Further studies to investigate these disparities are indicated.

Trends and Socioeconomic Health Outcomes of Cannabis Use Among Patients With Gastroparesis: A United States Nationwide Inpatient Sample Analysis.

BACKGROUND: Although cannabis may worsen nausea and vomiting for patients with gastroparesis, it may also be an effective treatment for gastroparesis-related abdominal pain. Given conflicting data and a lack of current epidemiological evidence, we aimed to investigate the association of cannabis use on relevant clinical outcomes among hospitalized patients with gastroparesis. MATERIALS AND METHODS: Patients with a diagnosis of gastroparesis were reviewed from the National Inpatient Sample (NIS) database between 2008 and 2014. Gastroparesis was identified by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes with patients classified based on a diagnosis of cannabis use disorder. Demographics, comorbidities, socioeconomic status, and outcomes were compared between cohorts using χ2 and analysis of variance. Logistic regression was then performed and annual trends also evaluated. RESULTS: A total of 1,473,363 patients with gastroparesis were analyzed [n=33,085 (2.25%) of patients with concomitant cannabis use disorder]. Patients with gastroparesis and cannabis use disorder were more likely to be younger and male gender compared with nonusers (36.7±18.8 vs. 51.9±16.8; P<0.001 and 52.9% vs. 33.5%; P<0.001, respectively). Race/ethnicity was different between groups (P<0.001). Cannabis users had a lower median household income and were more likely to have Medicaid payor status (all P<0.001). Controlling for confounders, length of stay, and mortality were significantly decreased for patients with gastroparesis and cannabis use (all P<0.001). CONCLUSION: While patients with gastroparesis and cannabis use disorder were younger, with a lower socioeconomic status, and disproportionately affected by psychiatric diagnoses, these patients had better hospitalization outcomes, including decreased length of stay and improved in-hospital mortality.

Single session endoscopic ultrasound-guided double bypass (hepaticogastrostomy and gastrojejunostomy) for concomitant duodenal and biliary obstruction: A case series.

BACKGROUND: Concomitant malignant biliary and gastric outlet obstruction can be difficult to manage endoscopically with traditional endoscopic retrograde cholangiopancreatography (ERCP) and luminal stenting. Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HG) and gastrojejunostomy (GJ) are novel techniques that can relieve both obstructions in a single session. This study aims to describe the outcomes of combined, single session EUS-HG and EUS-GJ. METHODS: This is a two-center retrospective study of consecutive patients who underwent same session EUS-HG and EUS-GJ. The primary outcome was technical success. Secondary outcomes included adverse events (AE), reduction in total serum bilirubin, length of hospital stay (LOS), and re-intervention rates. RESULTS: A total of 23 patients underwent EUS-HG and EUS-GJ (12 males, mean age 66.4 years). Twenty-one were performed for malignant obstruction. Technical success was 100% and 95.6% for HG and GJ, respectively. All patients subsequently tolerated a soft diet and 72.7% (16/22) of patients had a 50% reduction in bilirubin post-procedure. The median LOS for the 17 patients who were not discharged home immediately following the procedure was 2 (range 1-20) days. There were five AEs (2 mild, 3 moderate). Only three patients required reintervention (interventional radiology-guided biliary drainage, stent exchange for a benign biliary stricture, and placement of a second stent through an occluded distal common bile duct stent) over a median follow-up of 78 days. One patient with pancreatic cancer underwent successful tumor resection. CONCLUSION: Single session EUS-guided double bypass (HG and GJ) is technically feasible and safe when conducted by experienced endosonographers. Larger, comparative studies are needed.

EUS-guided transhepatic biliary drainage: a large single-center U.S. experience.

BACKGROUND AND AIMS: EUS-guided hepaticogastrostomy has been performed for many years with most published experience from outside the United States. The luminal access point can be from the esophagus, stomach, duodenum, or jejunum; biliary access can be either into the right or left intrahepatic system. Thus, we prefer the term EUS-guided transhepatic biliary drainage (ETBD). We describe what is believed to be the largest single-center U.S. experience of ETBD for management of benign and malignant biliary disease. METHODS: This was a retrospective study of all ETBD conducted by 1 endoscopist between September 2014 and May 2021. RESULTS: Two hundred fifteen patients underwent attempted ETBD: 85 for benign disease and 130 for malignant disease. Ninety-two patients (43%) had surgically altered anatomy (SAA). In 94 patients previously endoscopic attempts failed. The approach was transesophageal in 9, transgastric in 188, transduodenal in 5, and transjejunal in 5 patients. In 1 patient a bilateral approach was used. Standard fully covered self-expandable stents of 4- to 10-cm lengths and 8- or 10-mm diameters were used. Technical success was 95.3% and clinical success was 87.25%. Forty patients (18.6%) experienced adverse events (13 mild, 21 moderate, and 6 severe according to the modified American Society for Gastrointestinal Endoscopy lexicon). Mean follow-up was 257.31 ± 308.11 days for all patients (124.53 ± 229.86 days for benign disease and 457.27 ± 466.31 days for malignant disease). Seventy-four patients (34.4%) had died at the time of data collection (66 in the malignant cohort, 8 in the benign cohort). Of those with malignancy surviving >6 months, 17.4% required reintervention. CONCLUSIONS: ETBD is effective in the management of benign and malignant biliary obstruction for patients with SAA as well as native anatomy, with a modest adverse event rate.

Novel Advanced Impedance Metrics on Impedance-pH Testing Predict Lung Function Decline in Idiopathic Pulmonary Fibrosis.

INTRODUCTION: Gastroesophageal reflux has been associated with idiopathic pulmonary fibrosis (IPF). Mean nocturnal baseline impedance (MNBI) is a marker of esophageal mucosal integrity, whereas postreflux swallow-induced peristaltic wave (PSPW) index reflects esophageal chemical clearance. Both metrics offer novel ways to assess reflux burden on multichannel intraluminal impedance-pH testing (MII-pH), but their role in extraesophageal reflux remains unclear. We aimed to evaluate the relationship between these novel metrics and lung function decline in patients with IPF. METHODS: Adults with IPF undergoing prelung transplant MII-pH were enrolled. All patients completed pulmonary function testing (PFT) at the time of MII-pH and at the 1-year follow-up. MNBI was calculated by averaging baseline impedance at three 10-minute intervals (1 AM/2 AM/3 AM). PSPW index was the proportion of all reflux episodes, followed by a peristaltic swallow within 30 seconds. Univariate (Student t-test/Pearson correlation) and multivariable (general linear regression) analyses were performed. RESULTS: One hundred twenty-five subjects (mean age = 61.7 years, 62% men) were included. Forced expiratory volume in one second and forced vital capacity declined more significantly over 12 months in subjects with lower distal MNBI, proximal MNBI, and PSPW index (all P < 0.05). On multivariable analyses adjusting for age, sex, proton pump inhibitor use, and baseline lung function, distal MNBI (ß = -10.86, P = 0.024; ß = -8.03, P = 0.045), proximal MNBI (ß = -13.5, P = 0.0068; ß = -9.80, P = 0.025), and PSPW index (ß = -18.1, P = 0.010; ß = -12.55, P = 0.050) remained predictive of greater forced expiratory volume in one second and forced vital capacity decline. DISCUSSION: Low distal MNBI, proximal MNBI, and PSPW index independently predicted more severe lung function decline over 1 year in patients with IPF. These impedance metrics may have prognostic value and support a role for reflux in IPF pathogenesis.

Endoscopic band ligation in the treatment of gastric antral vascular ectasia: a systematic review and meta-analysis.

Background and study aims While argon plasma coagulation (APC) is the first-line treatment for gastric antral vascular ectasia (GAVE), endoscopic band ligation (EBL) has shown promising results. The aim of this study was to perform a systematic review and meta-analysis to evaluate the effectiveness of EBL for the treatment of GAVE. Methods Individualized search strategies were developed in accordance with PRISMA and MOOSE guidelines through September 1, 2020. Measured outcomes included endoscopic success (defined as GAVE eradication/improvement), change in hemoglobin, transfusion dependency, number of treatment sessions, adverse events, rebleeding, and bleeding-associated mortality. Outcomes were compared among studies evaluating EBL versus APC. Results Eleven studies (n = 393; 59.39 % female; mean age 58.65 ±â€Š8.85 years) were included. Endoscopic success was achieved in 87.84 % [(95 % CI, 80.25 to 92.78); I 2  = 11.96 %] with a mean number of 2.50 ±â€Š0.49 treatment sessions and average of 12.40 ±â€Š3.82 bands applied. For 8 studies comparing EBL (n = 143) versus APC (n = 174), there was no difference in baseline patient characteristics. However, endoscopic success was significantly higher for EBL [OR 6.04 (95 % CI 1.97 to 18.56; P  = 0.002], requiring fewer treatment sessions (2.56 ±â€Š0.81 versus 3.78 ±â€Š1.17; P  < 0.001). EBL was also associated with a greater increase in post-procedure hemoglobin [mean difference 0.35 (95 % CI 0.07 to 0.62; P  = 0.0140], greater reduction in transfusions required [mean difference -1.46 (95 % CI -2.80 to -0.12; P  = 0.033], and fewer rebleeding events [OR 0.11 (95 % CI, 0.04 to 0.36); P  < 0.001]. There was no difference in adverse events or bleeding-associated mortality ( P  > 0.050). Conclusions EBL appears to be safe and effective for treatment of GAVE, with improved outcomes when compared to APC.

Endoscopic gallbladder drainage for symptomatic gallbladder disease: a cumulative systematic review meta-analysis.

BACKGROUND: Endoscopic ultrasound (EUS)-guided transmural or endoscopic retrograde cholangiography (ERC)-based transpapillary drainage may provide alternative treatment strategies for high-risk surgical candidates with symptomatic gallbladder (GB) disease. The primary aim of this study was to perform a systematic review and meta-analysis to investigate the efficacy and safety of endoscopic GB drainage for patients with symptomatic GB disease. METHODS: Searches of PubMed, EMBASE, Web of Science, and Cochrane Library databases were performed in accordance with PRISMA and MOOSE guidelines. Pooled proportions were calculated for measured outcomes including technical success, clinical success, adverse event rate, recurrence rate, and rate of reintervention. Subgroup analyses were performed for transmural versus transpapillary, transmural lumen apposing stent (LAMS), and comparison to percutaneous transhepatic drainage. Heterogeneity was assessed with I2 statistics. Publication bias was ascertained by funnel plot and Egger regression testing. RESULTS: Thirty-six studies (n = 1538) were included. Overall, endoscopic GB drainage achieved a technical and clinical success of 87.33% [(95% CI 84.42-89.77); I2 = 39.55] and 84.16% [(95% CI 80.30-87.38); I2 = 52.61], with an adverse event rate of 11.00% [(95% CI 9.25-13.03); I2 = 7.08]. On subgroup analyses, EUS-guided transmural compared to ERC-assisted transpapillary drainage resulted in higher technical and clinical success rates [OR 3.91 (95% CI 1.52-10.09); P = 0.005 and OR 4.59 (95% CI 1.84-11.46); P = 0.001] and lower recurrence rate [OR 0.17 (95% CI 0.06-0.52); P = 0.002]. Among EUS-guided LAMS studies, technical success was 94.65% [(95% CI 91.54-96.67); I2 = 0.00], clinical success was 92.06% [(95% CI 88.65-94.51); I2 = 0.00], and adverse event rate was 11.71% [(95% CI 8.92-15.23); I2 = 0.00]. Compared to percutaneous drainage, EUS-guided drainage possessed a similar efficacy and safety with significantly lower rate of reintervention [OR 0.05 (95% CI 0.02-0.13); P < 0.001]. DISCUSSION: Endoscopic GB drainage is a safe and effective treatment for high-risk surgical candidates with symptomatic GB disease. EUS-guided transmural drainage is superior to transpapillary drainage and associated with a lower rate of reintervention compared to percutaneous transhepatic drainage.

Safety and sedation-associated adverse event reporting among patients undergoing endoscopic cholangiopancreatography: a comparative systematic review and meta-analysis.

BACKGROUND AND AIM: There is wide variation in choice of sedation and airway management for endoscopic retrograde cholangiopancreatography (ERCP). The aim of this study was to perform a systematic review and meta-analysis to investigate safety outcomes of deep sedation with monitored anesthesia care (MAC) versus general endotracheal anesthesia (GETA). METHODS: Individualized search strategies were performed in accordance with PRISMA and MOOSE guidelines. This meta-analysis was performed by calculating pooled proportions using random effects models. Measured outcomes included procedure success, all-cause and anesthesia-associated adverse events, and post-procedure recovery time. Heterogeneity was assessed with I2 statistics and publication bias by funnel plot and Egger regression testing. RESULTS: Five studies (MAC: n = 1284 vs GETA: n = 615) were included. Patients in the GETA group were younger, had higher body mass index (BMI), and higher mean ASA scores (all P < 0.001) with no difference in Mallampati scores (P = 0.923). Procedure success, all-cause adverse events, and anesthesia-associated events were similar between groups [OR 1.16 (95% CI 0.51-2.64); OR 1.16 (95% CI 0.29-4.70); OR 1.33 (95% CI 0.27-6.49), respectively]. MAC resulted in fewer hypotensive episodes [OR 0.32 (95% CI 0.12-0.87], increased hypoxemic events [OR 5.61 (95% CI 1.54-20.37)], and no difference in cardiac arrhythmias [OR 0.48 (95% CI 0.13-1.78)]. Procedure time was decreased for MAC [standard difference - 0.39 (95% CI - 0.78-0.00)] with no difference in recovery time [standard difference - 0.48 (95% CI - 1.04-0.07)]. CONCLUSIONS: This study suggests MAC may be a safe alternative to GETA for ERCP; however, MAC may not be appropriate in all patients given an increased risk of hypoxemia.

Healthcare Disparities in the Management of Acute Cholecystitis: Impact of Race, Gender, and Socioeconomic Factors on Cholecystectomy vs Percutaneous Cholecystostomy.

BACKGROUND: While percutaneous cholecystostomy (PC) is a recommended treatment strategy in lieu of cholecystectomy (CCY) for acute cholecystitis among patients who may not be considered good surgical candidates, reports on disparities in treatment utilization remain limited. The aim of this study was to investigate the role of demographic, clinical, and socioeconomic factors in treatment of acute cholecystitis. METHODS: Patients with a diagnosis of acute cholecystitis who underwent CCY versus PC were reviewed from the U.S. Nationwide Inpatient Sample (NIS) database between 2008-2014. Measured variables including age, race/ethnicity, Charlson comorbidity index (CCI), hospital type/region, insurance payer, household income, length of stay (LOS), hospital cost, and mortality were compared using chi-square and ANOVA. Multivariable logistic regression was performed to identify specific predictors of cholecystitis treatment. RESULTS: A total of 1,492,877 patients (CCY:n=1,435,255 versus PC:n=57,622) were analyzed. The majority of patients that received PC were at urban teaching hospitals (65.2%). LOS was significantly longer with higher associated costs for PC [(11.1±11.0 versus 4.5±5.3 days; P<0.001) and ($99577±138850 versus $48399±58330; P<0.001)]. Mortality was also increased for patients that received PC compared to CCY (8.8% versus 0.6%; P<0.001). Multivariable regression demonstrated multiple socioeconomic and healthcare-related factors influencing the utilization of PC including male gender, Black or Asian race/ethnicity, Medicare payer status, urban hospital location, and household income (all P<0.001). CONCLUSION: Although patients receiving PC had higher CCI scores, multiple socioeconomic and healthcare related factors appeared to also influence this treatment decision. Additional studies to investigate these disparities are indicated to improve outcomes for all individuals with this condition.

How Do Presenting Symptoms and Outcomes Differ by Race/Ethnicity Among Hospitalized Patients With Coronavirus Disease 2019 Infection? Experience in Massachusetts.

BACKGROUND: Population-based literature suggests severe acute respiratory syndrome coronavirus 2 infection may disproportionately affect racial/ethnic minorities; however, patient-level observations of hospitalization outcomes by race/ethnicity are limited. Our aim in this study was to characterize coronavirus disease 2019 (COVID-19)-associated morbidity and in-hospital mortality by race/ethnicity. METHODS: This was a retrospective analysis of 9 Massachusetts hospitals including all consecutive adult patients hospitalized with laboratory-confirmed COVID-19. Measured outcomes were assessed and compared by patient-reported race/ethnicity, classified as white, black, Latinx, Asian, or other. Student t test, Fischer exact test, and multivariable regression analyses were performed. RESULTS: A total of 379 patients (aged 62.9 ± 16.5 years; 55.7% men) with confirmed COVID-19 were included (49.9% white, 13.7% black, 29.8% Latinx, 3.7% Asian), of which 376 (99.2%) were insured (34.3% private, 41.2% public, 23.8% public with supplement). Latinx patients were younger, had fewer cardiopulmonary disorders, were more likely to be obese, more frequently reported fever and myalgia, and had lower D-dimer levels compared with white patients (P < .05). On multivariable analysis controlling for age, gender, obesity, cardiopulmonary comorbidities, hypertension, and diabetes, no significant differences in in-hospital mortality, intensive care unit admission, or mechanical ventilation by race/ethnicity were found. Diabetes was a significant predictor for mechanical ventilation (odds ratio [OR], 1.89; 95% confidence interval [CI], 1.11-3.23), while older age was a predictor of in-hospital mortality (OR, 4.18; 95% CI, 1.94-9.04). CONCLUSIONS: In this multicenter cohort of hospitalized COVID-19 patients in the largest health system in Massachusetts, there was no association between race/ethnicity and clinically relevant hospitalization outcomes, including in-hospital mortality, after controlling for key demographic/clinical characteristics. These findings serve to refute suggestions that certain races/ethnicities may be biologically predisposed to poorer COVID-19 outcomes.

Endoscopic vacuum therapy versus endoscopic stenting for upper gastrointestinal transmural defects: Systematic review and meta-analysis.

BACKGROUND: Upper gastrointestinal fistulas, leaks, and perforations represent a high cost burden to health systems worldwide, with high morbidity and mortality rates for affected patients. Management of these transmural defects remains therapeutically challenging. OBJECTIVES: The aim of this study is to perform a systematic review and meta-analysis to investigate the efficacy and safety of self-expanding metal stents (SEMS) versus endoscopic vacuum therapy (EVT) for treatment of upper gastrointestinal transmural defects. METHODS: Searches were performed on MEDLINE, EMBASE, Central Cochrane, Latin American and Caribbean Health (LILACS), and gray literature, as well as a manual search to identify studies comparing SEMS versus EVT to treat upper gastrointestinal transmural defects. Evaluated outcomes were: rates of successful closure, mortality, length of hospital stay, duration of treatment, and adverse events. RESULTS: Five studies with a total of 274 patients were included. There was a 21% increase in successful fistula closure attributed to EVT compared with the SEMS group (RD 0.21, CI 0.10-0.32; P = 0.0003). EVT demonstrated a 12% reduction in mortality compared to stenting (RD 0.12, CI 0.03-0.21; P = 0.006) and an average reduction of 14.22 days in duration of treatment (CI 8.38-20.07; P < 0.00001). There was a 24% reduction in adverse events (RD 0.24, CI 0.13-0.35; P = 0.0001. There were no statistical differences between the studied therapies regarding the length of hospital stay. CONCLUSION: Endoscopic vacuum therapy proves to be superior in successful defect closure, mortality, adverse events and duration of treatment.
