RESUMO
BACKGROUND AND AIMS: The gas-filled intragastric balloon (IGB) system (Obalon) and the fluid-filled IGB system (Orbera) are the current FDA-approved IGB systems to treat obesity; however, they have not been previously compared in clinical practice. The aims of this study were to compare their efficacy, tolerance, and safety in a clinical setting. MATERIALS AND METHODS: This is a retrospective cohort study of consecutive patients treated with the gas-filled IGB or fluid-filled IGB between October 2015 and May 2020 at 2 academic centers. The primary endpoints included percent total body weight loss at balloon removal in patients who completed at least 20 weeks of therapy, the difference in adverse events that required urgent evaluation or hospitalization, and early removal in the 2 groups. RESULTS: A total of 87 patients underwent successful IGB placement (gas-filled IGB n=57, age 48.9±8.8, body mass index 35.5±5 kg/m 2 ; fluid-filled IGB n=30, age 49.2±14.3, body mass index 38.8±6 kg/m 2 ). Eleven patients underwent early device removal. There were no differences in percent total body weight loss at balloon removal and 12 months between the balloon systems ( P =0.39). Patients who received the fluid-filled IGB were more likely to require urgent evaluation or treatment, require hospital stay >24 hours, and need early balloon system removal compared with patients treated with the gas-filled IGB. CONCLUSION: In this 2-center cohort, both FDA-approved gastric balloon systems had the same effectiveness, but the gas-filled IGB had fewer serious adverse events and better tolerability than the fluid-filled IGB.

BACKGROUND: Flexible endoscopic therapy of Zenker's diverticulum using submucosal tunneling (Z-POEM) similar to esophageal Per-Oral Endoscopic Myotomy (POEM) is becoming increasingly common. However, data comparing Z-POEM with traditional flexible endoscopic septotomy (FES) are sparse. The aim of this study was to compare outcomes of Z-POEM with traditional FES over a medium-term follow-up period. METHODS: This was a prospective study of patients who underwent Z-POEM for treatment of Zenker's diverticulum between 2018 and 2020 at a tertiary academic medical center compared to prior patients who had FES (between 2015 and 2018). Procedural characteristics and clinical outcomes (technical and clinical success, and adverse events) were compared between patients who underwent each treatment. RESULTS: A total of 28 patients underwent ZD therapy during the study period. 13 patients (mean age 70 years; 77% male) underwent Z-POEM and 15 patients (mean age 72 years; 73% male) underwent traditional FES. The mean Zenker's diverticulum size was 2.4 ± 0.6 cm in the ZPOEM group vs 2.5 ± 0.8 cm in the FES group. The mean procedure time was similar between groups: 43.9 min (range 26-66) in the Z-POEM group and 60.2 min (range 25-92) in the traditional FES group (t = 1.74 p = 0.19). Overall technical success was seen in 100% of patients. There was one adverse event in the FES group (dehydration resulting in near-syncope) (1/28, 3.6%). Overall clinical success was seen in 92.8% (26/28) of patients and was not significantly different between groups (Z-POEM; 13/13, 100% vs FES; 13/15, 86.7%, t = - 1.36 p = 0.18). CONCLUSION: This prospective study suggests that ZPOEM is an effective technique for the treatment of Zenker's diverticulum with no significant differences in clinical outcomes or adverse event rates when compared to traditional FES.

BACKGROUND: Death after endoscopy is rare, under-reported, and has variable causes. This study aimed to evaluate the incidence and causes of fatal endoscopic adverse events (AEs) across two academic medical centers and to identify patient-, procedure-, and sedation-related risk factors. METHODS: This is a retrospective cohort study of fatal adverse events causally related to endoscopy at Denver Health Medical Center and the University of Colorado Hospital from 2011 to 2020. Fatal AEs were retrieved from the physician-reported database. Electronic medical records were then reviewed to determine medical history, procedure details, subsequent treatments, and time and cause of death. RESULTS: From January 2011 to January 2020, 146,010 GI endoscopy procedures were performed. Median patient age was 70 [51-78] and 57% were male. Thirty-one deaths were identified, 28 of which were attributed to endoscopy, yielding a procedure-related fatality rate of 0.018%. Procedures included 11 EGDs, one colonoscopy, two flexible sigmoidoscopies, six ERCPs, seven upper EUS, and one PEG-J tube placement. Specific causes of death included aspiration in four patients (14%); cardiac arrest or myocardial infarction in seven patients (25%); perforation in nine patients (32%); bleeding in four patients (14%); cholangitis or sepsis without perforation in three patients (11%); and acute pancreatitis in one patient (3.6%). CONCLUSIONS: Fatal endoscopic AEs were rare but tended to occur in older patients with major comorbidities. Most deaths occurred from aspiration pneumonia, cardiac arrest, or perforation-related sepsis within 1 week of the procedure.

BACKGROUND AND AIMS: Despite recent advances, patients with pancreaticobiliary cancers have a poor prognosis. We previously demonstrated the efficacy of endoscopic ultrasound (EUS) guided acquisition of portal vein (PV) blood for enumeration of circulating tumor cells (CTCs). The aim of this study was to assess PV-CTCs as potential biomarkers for the assessment of progression-free (PFS) and overall survival (OS) in patients with pancreaticobiliary cancers. METHODS: 17 patients with biopsy-proven pancreaticobiliary malignancy were enrolled. CTCs were enumerated from both peripheral and PV blood. All patients were followed until death. PFS and OS were evaluated with the log-rank test and summarized with the use of Kaplan-Meier methods. Unadjusted and adjusted Cox-proportional hazards models were fitted to study the relationship between PV-CTCs and PFS and OS. RESULTS: After 3.5 years of follow-up, all patients had expired. PV-CTCs were detected in all patients (median PV-CTCs 62.0/7.5 mL (interquartile range [IQR] 17-132). The mean PFS in patients with PV-CTCs <185/7.5 mL was significantly longer than patients with PV-CTCs ≥185/7.5 mL (43.3 weeks vs. 12.8 weeks, log-rank p = 0.002). The mean OS in patients with PV-CTCs <185/7.5 mL was significantly longer than patients with PV-CTCs ≥185/7.5 mL (75.8 weeks vs. 29.5 weeks, log-rank p = 0.021). In an adjusted Cox-proportional hazards model, PV-CTCs were significant predictors of both PFS and OS (HR 1.004, p = 0.037; HR 1.004, p = 0.044 respectively). CONCLUSION: In this pilot and feasibility study, EUS-acquired PV-CTCs predicted PFS and OS. Our findings suggest that PV-CTCs can help provide important prognostic data for both providers and patients.

OBJECTIVES: Morbid obesity may adversely affect the clinical course of acute pancreatitis (AP); however, there are no inpatient, population-based studies assessing the impact of morbid obesity on AP-related outcomes. We sought to evaluate the impact of morbid obesity on AP-related clinical outcomes and health-care utilization. METHODS: The Nationwide Inpatient Sample (2007-2011) was reviewed to identify all adult inpatients (≥18 years) with a principal diagnosis of AP. The primary clinical outcomes (mortality, renal failure, and respiratory failure) and secondary resource outcomes (length of stay and hospital charges) were analyzed using univariate and multivariate comparisons. Propensity score-matched analysis was performed to compare the outcomes in patients with and without morbid obesity. RESULTS: Morbid obesity was associated with 3.9% (52,297/1,330,302) of all AP admissions. Whereas the mortality rate decreased overall (0.97%â0.83%, P<0.001), it remained unchanged in those with morbid obesity (1.02%â1.07%, P=1.0). Multivariate analysis revealed that morbid obesity was associated with increased mortality (odds ratio (OR) 1.6; 95% confidence interval (CI) 1.3, 1.9), prolonged hospitalization (0.4 days; P<0.001), and higher hospitalization charges ($5,067; P<0.001). A propensity score-matched cohort analysis demonstrated that the primary outcomes, acute kidney failure (10.8 vs. 8.2%; P<0.001), respiratory failure (7.9 vs. 6.4%; P<0.001), and mortality (OR 1.6, 95% CI 1.2, 2.1) were more frequent in morbid obesity. CONCLUSIONS: Morbid obesity negatively influences inpatient hospitalization and is associated with adverse clinical outcomes, including mortality, organ failure, and health-care resource utilization. These observations and the increasing global prevalence of obesity justify ongoing efforts to understand the role of obesity-induced inflammation in the pathogenesis and management of AP.

BACKGROUND: Recent studies have suggested that sleeve gastrectomy (SG) is associated with the development of Barrett esophagus (BE) even in the absence of gastroesophageal reflux disease (GERD) symptoms. OBJECTIVE: The aim of this study was to assess the rates of upper endoscopy and incidence of new BE diagnoses in patients undergoing SG. SETTING: This was a claims-data study of patients who underwent SG between 2012 and 2017 while enrolled in a U.S. statewide database. METHODS: Diagnostic claims data were used to identify pre- and postoperative rates of upper endoscopy, GERD, reflux esophagitis, and BE. Time-to-event analysis using a Kaplan-Meier approach was performed to estimate the cumulative postoperative incidence of these conditions. RESULTS: We identified 5562 patients who underwent SG between 2012 and 2017. Of these, 1972 patients (35.5%) had at least 1 diagnostic record of upper endoscopy. The preoperative incidences of a diagnosis of GERD, esophagitis, and BE were 54.9%, 14.6%, and .9%, respectively. The predicted postoperative incidences of GERD, esophagitis, and BE, respectively, were 18%, 25.4%, and 1.6% at 2 years and 32.1%, 85.0%, and 6.4% at 5 years. CONCLUSIONS: In this large statewide database, rates of esophagogastroduodenoscopy remained low after SG, but the incidence of a new postoperative esophagitis or BE diagnosis in patients who underwent esophagogastroduodenoscopy was higher than in the general population. Patients undergoing SG may have a disproportionately high risk of developing reflux complications including BE after surgery.

RESUMO
INTRODUCTION: Endoscopic transoral outlet reduction (TORe) has emerged as a safe and effective treatment option for weight regain after Roux-en-Y Gastric Bypass (RYGB). Factors that predict successful weight loss after TORe are incompletely understood. The aims of this study were to evaluate procedural factors and patient factors that may affect percent total body weight loss (%TBWL) after TORe. METHODS: A retrospective cohort study was performed on patients after TORe. The primary outcomes were %TBWL at 6 and 12 months based on four procedural factors: purse-string (PS) vs. non-purse-string (NPS) suture pattern, gastric pouch sutures (N), change in the diameter of the gastrojejunal anastomosis, and change in the length of the gastric pouch. Secondary outcomes included patient factors that affected weight loss. RESULTS: Fifty-one patients underwent TORe. Weight loss for completers was 11.3 ± 7.6% and 12.2 ± 9.2% at 6 and 12 months. There was a correlation between %TBWL and change in pouch length at 6 and 12 months and number of sutures in the pouch at 6 months. The difference in %TBWL between PS and NPS groups at 6 months (PS, n=21, 12.3 ± 8.5% and NPS, n=8, 8.7 ± 3.7%) and 12 months (PS, n=21, 13.5 ± 9.2% and NPS, n=5, 7.0 ± 7.9%) did not reach statistical significance. For secondary outcomes, depression was associated with %TBWL. CONCLUSION: Change in pouch length and number of sutures in the pouch correlated positively while depression correlated negatively with weight loss after TORe. Further studies are needed to understand these effects.

RESUMO
Tofacitinib is the only medicine in the class of Janus kinase (JAK) inhibitors that has been approved for use in moderate-to-severely active ulcerative colitis (UC). The potential of other JAK inhibitors to treat UC has not been fully explored. We present a case describing the successful use of the selective JAK inhibitor, ruxolitinib, to treat a patient with concomitant UC and polycythemia vera.
RESUMO
Rhabdomyolysis is a known rare and potentially lethal complication of statin use. This toxic effect is potentiated by alterations in hepatic physiology in patients with cirrhosis. Transjugular intrahepatic portosystemic shunt placement has the potential to further compound this effect; yet, examples of this have not previously been described in the literature. We present a case of a patient who experienced statin-induced rhabdomyolysis likely as a direct consequence of transjugular intrahepatic portosystemic shunt placement.
RESUMO
Aspiration therapy is a novel, endoscopic bariatric therapy that allows patients to remove a portion of an ingested meal through a modified percutaneous gastrostomy tube, called an A-Tube. Weight loss results from both fewer calories consumed, and from modifications in lifestyle and mealtime behaviors that patients make as a result of having the device installed. The first commercially available device for aspiration therapy, the AspireAssist (Aspire Bariatrics, King of Prussia, PA), was approved by the Food and Drug Administration in 2016 for weight loss for greater than 6 months duration in patients with a body mass index of 35-55. Multiple studies have demonstrated the effectiveness and safety of aspiration therapy, with low rates of adverse events related to the procedure, including no reported deaths, as well as no evidence of eating disorders developed during therapy. This chapter will describe our experience with aspiration therapy. We will describe how we select appropriate candidates for aspiration therapy, how we perform the procedure including a summary of the equipment used, and how we mitigate and manage complications of the procedure. This article will highlight the effectiveness of aspiration therapy as a novel and safe approach for weight loss in patients in obesity.

BACKGROUND: The outcomes of patients undergoing esophagogastroduodenoscopy (EGD) in the intensive care unit (ICU) for upper gastrointestinal bleeding (UGIB) are not well described. Our aims were to determine predictors of 30-day mortality and endoscopic intervention, and assess the utility of existing clinical-prediction tools for UGIB in this population. METHODS: Patients hospitalized in an ICU between 2008 and 2015 who underwent EGD were identified using a validated, machine-learning algorithm. Logistic regression was used to determine factors associated with 30-day mortality and endoscopic intervention. Area under receiver-operating characteristics (AUROC) analysis was used to evaluate established UGIB scoring systems in predicting mortality and endoscopic intervention in patients who presented to the hospital with UGIB. RESULTS: A total of 606 patients underwent EGD for UGIB while admitted to an ICU. The median age of the cohort was 62 years and 55.9% were male. Multivariate analysis revealed that predictors associated with 30-day mortality included American Society of Anesthesiologists (ASA) class (odds ratio [OR] 4.1, 95% confidence interval [CI] 2.2-7.9), Charlson score (OR 1.2, 95% CI 1.0-1.3), and duration from hospital admission to EGD (OR 1.04, 95% CI 1.01-1.07). Rockall, Glasgow-Blatchford, and AIMS65 scores were poorly predictive of endoscopic intervention (AUROC: 0.521, 0.514, and 0.540, respectively) and in-hospital mortality (AUROC: 0.510, 0.568, and 0.506, respectively). CONCLUSIONS: Predictors associated with 30-day mortality include ASA classification, Charlson score, and duration in the hospital prior to EGD. Existing risk tools are poorly predictive of clinical outcomes, which highlights the need for a more accurate risk-stratification tool to predict the benefit of intervention within the ICU population.
