Safety of EUS latex balloon use in patients with a latex allergy. Gastrointest Endosc 2024; 99:1032-1034. [PMID: 38280533 DOI: 10.1016/j.gie.2024.01.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 01/16/2024] [Accepted: 01/21/2024] [Indexed: 01/29/2024]
Abstract
BACKGROUND AND AIMS Balloons are used in EUS to improve visualization. However, data on the safety of latex balloons in patients with latex allergies are limited, and nonlatex alternatives can be costly. We investigated the safety of latex balloon use during EUS. METHODS A retrospective review was conducted at a tertiary center between 2019 and 2022. Patients with reported latex allergies who underwent linear EUS were included. Baseline demographics, EUS characteristics, and adverse events were collected. The primary outcome was the rate of adverse events. RESULTS Eighty-seven procedures were performed on 57 unique patients (mean age, 65.3 ± 14.5 years). Latex balloons were used in 59 procedures (67.8%), with only 8 procedures (13.6%) using prophylactic medications. No adverse events occurred during or after procedures, regardless of medication use or history of anaphylaxis. CONCLUSIONS The use of EUS latex balloons in patients with a latex allergy was associated with no adverse events.

A novel blood-sensing capsule for rapid detection of upper GI bleeding: a prospective clinical trial. Gastrointest Endosc 2024; 99:712-720. [PMID: 38065512 DOI: 10.1016/j.gie.2023.11.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 11/07/2023] [Accepted: 11/23/2023] [Indexed: 04/24/2024]
Abstract
BACKGROUND AND AIMS Upper GI bleeding (UGIB) is a common medical emergency associated with high resource utilization, morbidity, and mortality. Timely EGD can be challenging from personnel, resource, and access perspectives. PillSense (EnteraSense Ltd, Galway, Ireland) is a novel swallowed bleeding sensor for the detection of UGIB, anticipated to aid in patient triage and guide clinical decision-making for individuals with suspected UGIB. METHODS This prospective, open-label, single-arm comparative clinical trial of a novel bleeding sensor for patients with suspected UGIB was performed at a tertiary care center. The PillSense system consists of an optical sensor and an external receiver that processes and displays data from the capsule as "Blood Detected" or "No Blood Detected." Patients underwent EGD within 4 hours of capsule administration; participants were followed up for 21 days to confirm capsule passage. RESULTS A total of 126 patients were accrued to the study (59.5% male; mean age, 62.4 ± 14.3 years). Sensitivity and specificity for detecting the presence of blood were 92.9% (P = .02) and 90.6% (P < .001), respectively. The capsule's positive and negative predictive values were 74.3% and 97.8%, and positive and negative likelihood ratios were 9.9 and .08. No adverse events or deaths occurred related to the PillSense system, and all capsules were excreted from patients on follow-up. CONCLUSIONS The PillSense system is safe and effective for detecting the presence of blood in patients evaluated for UGIB before upper GI endoscopy. It is a rapidly deployed tool, with easy-to-interpret results that will affect the diagnosis and triage of patients with suspected UGIB. (Clinical trial registration number: NCT05385224.).

Clinical predictors of significant findings on EUS for the evaluation of incidental common bile duct dilation. Gastrointest Endosc 2024:S0016-5107(24)03161-4. [PMID: 38692515 DOI: 10.1016/j.gie.2024.04.2902] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 04/22/2024] [Accepted: 04/24/2024] [Indexed: 05/03/2024]
Abstract
BACKGROUND AND AIMS While endoscopic ultrasound(EUS) is highly accurate for the evaluation of common bile duct (CBD) dilation, the yield of EUS in patients with incidental CBD dilation is unclear. METHODS Serial patients undergoing EUS for incidental, dilated CBD (per radiologist, minimum >6mm objectively) from two academic medical centers, without active pancreaticobiliary disease or significantly elevated LFTs were evaluated. Multivariable logistic regression identified predictors of EUS with significant findings and a novel prediction model was derived from one center, internally validated with bootstrapping, and externally validated at the second center. RESULTS Of 375 patients evaluated, 31 (8.3%) had significant findings including 26 choledocholithiasis, 1 ampullary adenoma, and 1 pancreatic mass. Predictors of significant findings with EUS included: age ≥70(OR 3.7, 95CI 1.5-10.0), non-biliary-type abdominal pain without chronic pain(OR 6.1, 95CI 2.3-17.3), CBD diameter ≥15 mm or ≥17mm with cholecystectomy(OR 6.9, 95CI 2.7-18.7), and prior ERCP(OR 6.8, 95CI 2.1-22.5). A point-based novel clinical prediction model was created: age ≥70=1, non-biliary-type abdominal pain without chronic pain=2, prior ERCP=2, CBD dilation=2. A score <1 had 93% (development) and 100% (validation) sensitivity and predicted a <2% chance of having a significant finding in both cohorts while excluding the need for EUS in ∼30% of both cohorts. Conversely, a score >4 was >90% specific for the presence of significant pathology. CONCLUSION Less than 10% of patients undergoing EUS for incidental CBD dilation had pathologic findings. This novel, externally validated, clinical prediction model may reduce low-yield, invasive evaluation in nearly a third of patients.

Celiac artery mesenteric fat measurement with endosonography (CAMEUS) reliably correlates with obesity and related comorbidities. Gastroenterol Rep (Oxf) 2024; 12:goae039. [PMID: 38681751 PMCID: PMC11052652 DOI: 10.1093/gastro/goae039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 02/29/2024] [Accepted: 03/20/2024] [Indexed: 05/01/2024] Open
Abstract
Background Visceral fat represents a metabolically active entity linked to adverse metabolic sequelae of obesity. We aimed to determine if celiac artery mesenteric fat thickness can be reliably measured during endoscopic ultrasound (EUS), and if these measurements correlate with metabolic disease burden. Methods This was a retrospective analysis of patients who underwent celiac artery mesenteric fat measurement with endosonography (CAMEUS) measurement at a tertiary referral center, and a validation prospective trial of patients with obesity and nonalcoholic steatohepatitis who received paired EUS exams with CAMEUS measurement before and after six months of treatment with an intragastric balloon. Results CAMEUS was measured in 154 patients [56.5% females, mean age 56.5 ± 18.0 years, body mass index (BMI) 29.8 ± 8.0 kg/m2] and was estimated at 14.7 ± 6.5 mm. CAMEUS better correlated with the presence of non-alcoholic fatty liver disease (NAFLD) (R2 = 0.248, P < 0.001) than BMI (R2 = 0.153, P < 0.001), and significantly correlated with metabolic parameters and diseases. After six months of intragastric balloon placement, the prospective cohort experienced 11.7% total body weight loss, 1.3 points improvement in hemoglobin A1c (P = 0.001), and a 29.4% average decrease in CAMEUS (-6.4 ± 5.2 mm, P < 0.001). CAMEUS correlated with improvements in weight (R2 = 0.368), aspartate aminotransferase to platelet ratio index (R2 = 0.138), and NAFLD activity score (R2 = 0.156) (all P < 0.05). Conclusions CAMEUS is a novel measure that is significantly correlated with critical metabolic indices and can be easily captured during routine EUS to risk-stratify susceptible patients. This station could allow for EUS access to sampling and therapeutics of this metabolic region.

Endoscopic Ultrasound-based Shear Wave Elastography for Detection of Advanced Liver Disease. J Clin Gastroenterol 2024:00004836-990000000-00288. [PMID: 38648501 DOI: 10.1097/mcg.0000000000002013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 03/17/2024] [Indexed: 04/25/2024]
Abstract
BACKGROUND AND AIMS Endoscopic ultrasound shear wave elastography (EUS-SWE) is a novel modality for liver stiffness measurement. The aims of this study are to evaluate the performance and reliability of EUS-SWE for detecting advanced liver disease in a prospective cohort. METHODS EUS-SWE measurements were prospectively obtained from patients undergoing EUS between August 2020 and March 2023. Liver stiffness measurements were compared between patients with and without advanced liver disease (ALD), defined as stage ≥3, to determine diagnostic accuracy for advanced fibrosis and portal hypertension. Logistic regression was performed to identify variables that impact the reliability of EUS-SWE readings. Select patients underwent paired magnetic resonance elastography (MRE) for liver fibrosis correlation. RESULTS Patients with ALD demonstrated higher liver stiffness compared to healthy controls (left lobe: 17.6 vs. 12.7 kPa, P<0.001; median right lobe: 24.8 vs. 11.0 kPa, P<0.001). The area under the receiver operator characteristic (AUROC) for the detection of ALD was 0.73 and 0.80 for left and right lobe measurements, respectively. General anesthesia was associated with reliable EUS-SWE liver readings (odds ratio: 2.73, 95% CI: 1.07-7.39, P=0.040). Left lobe measurements correlated significantly with MRE with an increase of 0.11 kPa (95% CI: 0.05-0.17 kPA) for every 1 kPa increase on EUS-SWE. D. CONCLUSIONS SWE is a promising technology that can readily be incorporated into standard EUS examinations for the assessment of ALD.

The association between microvascular and macrovascular diseases and diabetes remission after bariatric surgery. Surg Endosc 2024; 38:1835-1843. [PMID: 38305895 DOI: 10.1007/s00464-024-10687-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 12/30/2023] [Indexed: 02/03/2024]
Abstract
BACKGROUND Type-2 diabetes mellitus (T2DM) results in detrimental vascular complications including both microvascular and macrovascular diseases. Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are effective weight-loss therapies that enhance T2DM remission. However, limited data are present regarding the association between diabetes-associated diseases before RYGB and SG with T2DM remission. METHODS This is a retrospective cohort study in patients with T2DM who underwent RYGB or SG. We collected data on preoperative microvascular (i.e., retinopathy, nephropathy, and neuropathy) and macrovascular (coronary artery disease, cerebrovascular accidents, and peripheral artery disease) diabetes-associated diseases. Our end points included assessment of association and cumulative effect of diabetes-associated diseases and disease remission. We also performed a multivariate logistic regression to evaluate the parameters associated with T2DM remission. RESULTS A total of 536 patients (67% female, 94% White) were included in this study. Patients without diabetes-associated diseases had an OR of 2.72 (95% CI 1.92 to 3.88) to achieve T2DM remission compared to patients with diabetes-associated diseases (27.9% vs 59.4%; p < 0.001). Importantly, there was an additive effect of the number of diabetes-associated diseases on the T2DM remission (p < 0.001). We demonstrate a significant association between HbA1c (p < 0.001), number of diabetes medications (p < 0.001), T2DM duration (p < 0.001), surgery type (p = 0.009), and insulin use (p = 0.04) with T2DM remission. CONCLUSION Patients with presurgical diabetes-associated diseases had a lower remission rate after RYGB and SG. Not only do these complications represent a more practical and consistent variable to predict T2DM remission, but also help planning a multidisciplinary management of patients with more severe T2DM.

Abstract
Background and study aims Endoscopic sleeve gastroplasty (ESG) is performed in clinical practice by gastroenterologists and bariatric surgeons. Given the increasing regulatory approval and global adoption, we aimed to evaluate real-world outcomes in multidisciplinary practices involving bariatric surgeons and gastroenterologists across the United States. Patients and methods We included adult patients with obesity who underwent ESG from January 2013 to August 2022 in seven academic and private centers in the United States. Patient and procedure characteristics, serious adverse events (SAEs), and weight loss outcomes up to 24 months were analyzed. SPSS (version 29.0) was used for all statistical analyses. Results A total of 1506 patients from seven sites included 235 (15.6%) treated by surgeons and 1271 (84.4%) treated by gastroenterologists. There were no baseline differences between groups. Gastroenterologists used argon plasma coagulation for marking significantly more often than surgeons ( P <0.001). Surgeons placed sutures in the fundus in all instances whereas gastroenterologist placed them in the fundus in less than 1% of the cases ( P <0.001>). Procedure times were significantly different between groups, with surgeons requiring approximately 20 minutes more during the procedure than gastroenterologists ( P <0.001). Percent total body weight loss (%TBWL) and percent responders achieving >10 and >15% TBWL were similar between the two groups at 12, 18, and 24 months. Rates of SAEs were low and similar at 1.7% for surgeons and 2.7% for gastroenterologists ( P >0.05). Conclusions Data from a large US cohort show significant and sustained weight loss with ESG and an excellent safety profile in both bariatric surgery and gastroenterology practices, supporting the scalability of the procedure across practices in a multidisciplinary setting.

Post-bariatric Surgery Changes in Secondary Esophageal Motility and Distensibility Parameters. Obes Surg 2024; 34:347-354. [PMID: 38123782 DOI: 10.1007/s11695-023-06959-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 12/23/2023]
Abstract
INTRODUCTION Despite the increasing number of bariatric procedures over the recent years, the physiological changes in secondary esophageal motility and distensibility parameters after surgery remain unknown. METHODS This is a retrospective, single-center cohort study comparing esophageal planimetry and gastroesophageal junction (GEJ) distensibility in post-bariatric surgery patients (Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and conversion/revisional patients (DH)) and native-anatomy patients with obesity (NAC). Distensibility refers to the area achieved with a certain amount of pressure, and secondary peristalsis represents the esophageal response to an intended obstruction. Patients with pre-surgical dysmotility symptoms were excluded from the study. RESULTS From November 2018 to January 2023, 167 patients were evaluated and eligible for this study (RYGB = 87, SG = 33, NAC = 22, DH = 25). In NAC cohort, 17/22 (77%) patients presented normal motility patterns compared to 35/87 (40%) RYGB, 12/33 (36%) SG, and 5/25 (20%) DH (p < 0.05 for all comparisons). The most common abnormal motility pattern for all three bariatric cohorts was absent contractions. DH patients generally had the highest mean maximum distensibility index averages, followed by SG, RYGB, and NAC. CONCLUSION Bariatric surgery affects esophageal and GEJ physiology, and it is associated with higher rates of secondary dysmotility. DH patients have even higher rates of dysmotility. Further studies assessing clinical data and their correlation with manometric and pH-metric findings are needed.

Abstract
INTRODUCTION Endoscopic sleeve gastroplasty (ESG) has gained popularity over the past decade and has been adopted in both academic and private institutions globally. We present outcomes of the largest cohort of patients from the United States undergoing ESG and evaluate these according to obesity class. METHODS We performed a retrospective analysis of adult patients who underwent ESG. Medical information was abstracted from the electronic record with weight records up to 2 years after ESG. Percent total body weight loss (%TBWL) at 6, 12, 18, and 24 months was calculated based on baseline weight at the procedure. SPSS (version 29.0) was used for all statistical analyses. RESULTS A total of 1,506 patients from 7 sites were included (501 Class I obesity, 546 Class II, and 459 Class III). Baseline demographics differed according to obesity class due to differences in age, body mass index (BMI), height, sex distribution, and race. As early as 6 months post-ESG, mean BMI for each class dropped to the next lower class and remained there through 2 years. %TWBL achieved in the Class III group was significantly greater when compared with other classes at all time points. At 12 months, 83.2% and 60.9% of patients had ≥10% and ≥15% TBWL for all classes. There were no differences in adverse events between classes. DISCUSSION Real-world data from a large cohort of patients of all BMI classes across the United States shows significant and sustained weight loss with ESG. ESG is safe to perform in a higher obesity class with acceptable midterm efficacy.

Abstract
BACKGROUND AND AIMS Coaxial double-pigtail plastic stent (DPPS) placement is often performed within lumen-apposing metal stents (LAMSs) for drainage of pancreatic fluid collections (PFCs) to prevent adverse events (AEs) such as stent occlusion and bleeding. This study compares the safety and outcomes of LAMSs alone versus LAMSs with coaxial DPPSs for PFC management. METHODS Patients undergoing drainage of a PFC with LAMSs were retrospectively identified and categorized as LAMS or LAMS/DPPS based on initial drainage strategy. The AE rate, AE type, and clinical success were extracted by chart review. RESULTS One hundred eighty-five individuals (83 LAMS, 102 LAMS/DPPS) were identified. No significant differences were found in rates of clinical success (75.9% LAMS vs 69.6% LAMS/DDPS, P = .34) or overall AEs (15.7% LAMS vs 15.7% LAMS/DPPS, P = .825). CONCLUSIONS In this comparative single-center study, placement of a coaxial DPPS for drainage of PFCs with LAMSs did not affect rates of AEs or clinical success.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is technically challenging in patients with Roux-en-Y gastric bypass (RYGB) due to altered anatomy. OBJECTIVE To compare the procedural and clinical outcomes of 4 different ERCP techniques in RYGB patients. SETTING Academic tertiary referral center in the United States. METHODS A retrospective cohort study including patients with RYGB anatomy who underwent an ERCP between January 2015 and September 2020. We compared procedural success and adverse events (AEs) rates of balloon-assisted enteroscopy (BAE), gastrostomy-assisted ERCP (GAE), endoscopic ultrasound (EUS)-directed transgastric ERCP (EDGE), and rendezvous guidewire-assisted ERCP (RGA). RESULTS Seventy-eight RYGB patients underwent a total of 132 ERCPs. The mean age was 60 ± 11.8 years, with female predominance (85.7%). The ERCP procedures performed were BAE (n = 64; 48.5%), GAE (n = 18; 13.7%), EDGE (n = 25; 18.9%), and RGA (n = 25; 18.9%), with overall procedure success rates of 64.1%, 100%, 89.5%, and 91.7%, respectively. All approaches were superior to BAE (GAE versus BAE, P = .003; EDGE versus BAE, P = .034; RGA versus BAE, P = .011). The overall AE rates were 10.9%, 11.1%, 15.8 %, and 25.0%, respectively. There was no statistical difference in AEs. There were also no differences in bleeding, post-ERCP pancreatitis, and perforation rates between the 4 approaches. CONCLUSION Procedure success was similar between GAE, RGA, and EDGE, but superior to BAE. AE rates were similar between approaches.

Abstract
Background Endoscopic sleeve gastroplasty (ESG) is a safe and effective obesity treatment. The individualized metabolic score (IMS) is a validated score that uses preoperative variables predicting T2D remission (DR) in bariatric surgery. Objectives We evaluated the applicability of using the IMS score to predict DR in patients after ESG. Design/Methods We performed a retrospective review of patients with obesity and T2D who underwent ESG. We calculated DR, IMS score, and severity, and divided patients based on IMS category. Results The cohort comprised 20 patients: 25% (5) mild, 55% (11) moderate, and 20% (4) severe IMS stages. DR was achieved in 60%, 45.5%, and 0% of patients with mild, moderate, and severe IMS scores (p = 0.08), respectively. IMS score was significantly associated with DR (p = 0.03), with the area under the curve of the receiver operating characteristic for predicting DR 0.85. Conclusion These pilot data demonstrate that the IMS score appears to be useful in predicting DR after ESG.

Abstract
Background and Aims Percutaneous gallbladder drainage has traditionally been the reference standard treatment for cholecystitis in patients deemed unfit for surgery. Endoscopic transpapillary gallbladder drainage has emerged as a reliable alternative that offers an internal, incisionless option in nonsurgical patients. The aim of this study was to describe techniques for successful selective cystic duct cannulation and gallbladder drainage during ERCP. Methods A series of endoscopic transpapillary gallbladder procedures is shown, including endoscopic and fluoroscopic video and images. Each case highlights best practices, devices, and techniques to aid with successful completion of challenging cases. Results Standard cystic duct cannulation and gallbladder access is described using a standard catheter and a 0.035-inch angled guidewire. Challenges to selective cystic duct cannulation are overcome using various approaches, including using a rotatable catheter system, downsizing to a smaller guidewire, occluding the proximal common hepatic duct with an occlusion balloon, and directly intubating the cystic duct using peroral cholangioscopy. Dilation of the cystic duct is performed using standard devices designed for biliary intervention, but smaller, percutaneous angioplasty balloons are used for small ducts and severe strictures. After dilation, a plastic, double-pigtail stent is deployed across the papilla, and access is reobtained in a similar fashion to place a second, parallel stent. To eliminate the need to re-access the gallbladder after initial stent deployment, a cytology brush catheter is repurposed to obtain dual-wire access within the gallbladder before initial stent deployment. Conclusions When the fundamentals of ERCP and the techniques described here are used, endoscopic transpapillary gallbladder drainage can be performed safely and effectively to treat cholecystitis in patients who are not surgical candidates.

Abstract
BACKGROUND The primary obesity surgery endoluminal 2.0 (POSE 2.0) procedure involves full-thickness gastric body plications to narrow the stomach using durable suture anchor pairs. We evaluated POSE 2.0 as a treatment strategy for nonalcoholic fatty liver disease (NAFLD) in patients with obesity. METHODS Adults with obesity and NAFLD were prospectively allocated based on their preference to undergo POSE 2.0 with lifestyle modification or lifestyle modification alone (control). Primary end points were improvement in controlled attenuation parameter (CAP) and resolution of hepatic steatosis at 12 months. Secondary end points included %total body weight loss (%TBWL), change in serum measures of hepatic steatosis and insulin resistance, and procedure safety. RESULTS 42 adult patients were included (20 in the POSE 2.0 arm and 22 in the control arm). At 12 months, POSE 2.0 significantly improved CAP, whereas lifestyle modification alone did not (P < 0.001 for POSE 2.0; P = 0.24 for control). Similarly, both resolution of steatosis and %TBWL were significantly higher with POSE 2.0 than with control at 12 months. Compared with controls, POSE 2.0 significantly improved liver enzymes, hepatic steatosis index, and aspartate aminotransferase to platelet ratio at 12 months. There were no serious adverse events. CONCLUSION : POSE 2.0 was effective for NAFLD in patients with obesity, with good durability and safety profile.

Utility of Urgent Endoscopic Retrograde Cholangiopancreatography in Patients with Predicted Mild Acute Pancreatitis and Cholestasis. Dig Dis Sci 2023; 68:4259-4265. [PMID: 37665426 DOI: 10.1007/s10620-023-08004-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 06/13/2023] [Indexed: 09/05/2023]
Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) within 72 h is suggested for patients presenting with acute biliary pancreatitis (ABP) and biliary obstruction without cholangitis. This study aimed to identify if urgent ERCP (within 24 h) improved outcomes compared to early ERCP (24-72 h) in patients admitted with predicted mild ABP. METHODS Patients admitted for predicted mild ABP defined as a bedside index of severity in acute pancreatitis score < 3 and underwent ERCP for biliary obstruction within 72 h of presentation during the study period were included. Patients with prior biliary sphincterotomy or surgically altered anatomy preventing conventional ERCP were excluded. The primary outcome was the development of moderately severe or severe pancreatitis based on the revised Atlanta classification. Secondary outcomes were the length of hospital stay, the need for ICU admission, and ERCP-related adverse events (AEs). RESULTS Of the identified 166 patients, baseline characteristics were similar between both the groups except for the WBC count (9.4 vs. 8.3/µL; p < 0.044) and serum bilirubin level (3.0 vs. 1.6 mg/dL; p < 0.0039). Biliary cannulation rate and technical success were both high in the overall cohort (98.8%). Urgent ERCP was not associated with increased development of moderately severe pancreatitis (10.4% vs. 15.7%; p = 0.3115). The urgent ERCP group had a significantly shorter length of hospital stay [median 3 (IQR 2-3) vs. 3 days (IQR 3-4), p < 0.01]. CONCLUSION Urgent ERCP did not impact the rate of developing more severe pancreatitis in patients with predicted mild ABP but was associated with a shorter length of hospital stay and a lower rate of hospital readmission.

Abstract
This clinical practice guideline from the American Society for Gastrointestinal Endoscopy provides an evidence-based approach to strategies to prevent endoscopy-related injury (ERI) in GI endoscopists. It is accompanied by the article subtitled "Methodology and Review of Evidence," which provides a detailed account of the methodology used for the evidence review. This document was developed using the Grading of Recommendations Assessment, Development and Evaluation framework. The guideline estimates the rates, sites, and predictors of ERI. Additionally, it addresses the role of ergonomics training, microbreaks and macrobreaks, monitor and table positions, antifatigue mats, and use of ancillary devices in decreasing the risk of ERI. We recommend formal ergonomics education and neutral posture during the performance of endoscopy, achieved through adjustable monitor and optimal procedure table position, to reduce the risk of ERI. We suggest taking microbreaks and scheduled macrobreaks and using antifatigue mats during procedures to prevent ERI. We suggest the use of ancillary devices in those with risk factors predisposing them to ERI.

Uncovered versus fully covered self-expandable metal stents for the management of distal malignant biliary obstruction. Gastrointest Endosc 2023; 98:577-584.e4. [PMID: 37201725 DOI: 10.1016/j.gie.2023.05.047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 05/02/2023] [Accepted: 05/11/2023] [Indexed: 05/20/2023]
Abstract
BACKGROUND AND AIM Self-expandable metal stents (SEMSs) are widely used for palliation of distal malignant biliary obstruction (dMBO). However, previous studies comparing the outcomes between uncovered SEMSs (UCSEMSs) and fully covered SEMSs (FCSEMSs) report conflicting results. This large cohort study aimed to compare the clinical outcomes between UCSEMSs and FCSEMSs for dMBO. METHODS A retrospective cohort study was performed in patients with dMBO who underwent either UCSEMS or FCSEMS placement between May 2017 and May 2021. Primary outcomes were rates of clinical success, adverse events (AEs), and unplanned endoscopic reintervention. Secondary outcomes were types of AEs, intervention-free stent patency, and management and outcomes of stent occlusion. RESULTS The cohort included 454 patients (364 in the UCSEMS group and 90 in the FCSEMS group). Median follow-up duration was 9.6 months and was similar between the 2 groups. Use of UCSEMSs and FCSEMSs had comparable clinical success (P = .250). However, use of UCSEMSs had significantly higher rates of AEs (33.5% vs 21.1%; P = .023) and unplanned endoscopic reintervention (27.0% vs 11.1%; P = .002). UCSEMSs had a higher rate of stent occlusion (26.9% vs 8.9%; P < .001) and shorter median time to stent occlusion (4.4 months vs 10.7 months; P = .002). Stent reintervention-free survival was higher in the FCSEMS group. FCSEMSs had a significantly higher rate of stent migration (7.8% vs 1.1%; P < .001), but patients in the FCSEMS group had similar rates of cholecystitis (.3% vs 1.1%; P = .872) and post-ERCP pancreatitis (6.3% vs 6.6%; P = .90). When UCSEMSs did occlude, placement of a coaxial plastic stent had a higher rate of stent reocclusion compared with coaxial SEMS placement (46.7% vs 19.7%; P = .007). CONCLUSION FCSEMSs should be considered for the palliation of dMBO because of lower rates of AEs, longer patency rates, and lower rates of unplanned endoscopic intervention.

Abstract
This document from the American Society for Gastrointestinal Endoscopy (ASGE) provides a full description of the methodology used in the review of the evidence used to inform the final guidance outlined in the accompanying Summary and Recommendations document regarding the role of endoscopic submucosal dissection (ESD) in the management of early esophageal and gastric cancers. This guideline used the Grading of Recommendations, Assessment, Development and Evaluation framework and specifically addresses the role of ESD versus EMR and/or surgery, where applicable, for the management of early esophageal squamous cell carcinoma (ESCC), esophageal adenocarcinoma (EAC), and gastric adenocarcinoma (GAC) and their corresponding precursor lesions. For ESCC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonulcerated cancer >15 mm, whereas in patients with similar lesions ≤15 mm, the ASGE suggests either ESD or EMR. The ASGE suggests against surgery for such patients with ESCC, whenever possible. For EAC, the ASGE suggests ESD over EMR for patients with early-stage, well-differentiated, nonulcerated cancer >20 mm, whereas in patients with similar lesions measuring ≤20 mm, the ASGE suggests either ESD or EMR. For GAC, the ASGE suggests ESD over EMR for patients with early-stage, well or moderately differentiated, nonulcerated intestinal type cancer measuring 20 to 30 mm, whereas for patients with similar lesions <20 mm, the ASGE suggests either ESD or EMR. The ASGE suggests against surgery for patients with such lesions measuring ≤30 mm, whereas for lesions that are poorly differentiated, regardless of size, the ASGE suggests surgical evaluation over endosic approaches.

Abstract
BACKGROUND Post-operative pancreatic fluid collections (POPFCs) can be drained using percutaneous or endoscopic approaches. The primary aim of this study was to compare rates of clinical success between endoscopic ultrasound-guided drainage (EUSD) with percutaneous drainage (PTD) in the management of symptomatic POPFCs after distal pancreatectomy. Secondary outcomes included technical success, total number of interventions, time to resolution, rates of adverse events (AEs), and POPFC recurrence. METHODS Adults who underwent distal pancreatectomy from January 2012 to August 2021 and developed symptomatic POPFC in the resection bed were retrospectively identified from a single academic center database. Demographic data, procedural data, and clinical outcomes were abstracted. Clinical success was defined as symptomatic improvement and radiographic resolution without requiring an alternate drainage modality. Quantitative variables were compared using a two-tailed t-test and categorical data were compared using Chi-squared or Fisher's exact tests. RESULTS Of 1046 patients that underwent distal pancreatectomy, 217 met study inclusion criteria (median age 60 years, 51.2% female), of whom 106 underwent EUSD and 111 PTD. There were no significant differences in baseline pathology and POPFC size. PTD was generally performed earlier after surgery (10 vs. 27 days; p < 0.001) and more commonly in the inpatient setting (82.9% vs. 49.1%; p < 0.001). EUSD was associated with a significantly higher rate of clinical success (92.5% vs. 76.6%; p = 0.001), fewer median number of interventions (2 vs. 4; p < 0.001), and lower rate of POPFC recurrence (7.6% vs. 20.7%; p = 0.007). AEs were similar between EUSD (10.4%) and PTD (6.3%, p = 0.28), with approximately one-third of EUSD AEs due to stent migration. CONCLUSION In patients with POPFCs after distal pancreatectomy, delayed drainage with EUSD was associated with higher rates of clinical success, fewer interventions, and lower rates of recurrence than earlier drainage with PTD.

Tubularization of the gastric pouch helps sustain weight loss after transoral outlet reduction for post-Roux-en-Y gastric bypass weight recurrence. Endosc Int Open 2023; 11:E829-E834. [PMID: 37719801 PMCID: PMC10504039 DOI: 10.1055/a-2117-8113] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 04/18/2023] [Indexed: 09/19/2023] Open
Abstract
Background and study aims Traditional transoral outlet reduction (TORe) is a minimally invasive endoscopic approach focused on reducing the aperture of the gastrojejunal (GJ) anastomosis, while the tubular transoral outlet reduction (tTORe) consists of tabularization of the distal pouch utilizing an O-shape gastroplasty suturing pattern. The primary aim of this study was to compare short-term weight loss between TORe and tTORe. Patients and methods Retrospective analysis of a prospectively maintained database was conducted at a tertiary care bariatric center of excellence. The study included patients with history of Roux-en-Y gastric bypass (RYGB) who had an endoscopic revision by TORe or tTORe and had follow-up data in their electronic medical record. The primary outcome was percent total body weight loss (%TBWL). Results A total of 128 patients were included (tTORe=85, TORe=43). At 3 and 6 months, the tTORe and TORe cohorts presented similar %TBWL (3 months: 8.5±4.9 vs. 7.3±6.0, P = 0.27 and 6 months: 8.1±7.4 vs. 6.8±5.6, P = 0.44). At 9 months, there was a trend toward greater weight loss in the tTORe cohort (9.7±8.6% vs. 5.1±6.8%, P = 0.053). At 12 months, the %TBWL was significantly higher in the tubularization group compared to the standard group (8.2±10.8 vs. 2.3±7.3%, P = 0.01). Procedure time was significantly different between both groups (60.5 vs. 53.4 minutes, P = 0.03). The adverse events rate was similar between groups (8.2% vs. 7.0% for tTORe and TORe, respectively, P = 0.61). Conclusions The tTORe enhances efficacy and durability of the standard procedure without adding significant procedure-related risks.

Abstract
BACKGROUND Delayed bleeding is among the most common adverse events associated with endoscopic mucosal resection (EMR) of nonampullary duodenal polyps. We evaluated the rate of delayed bleeding and complete defect closure using a novel through-the-scope (TTS) suturing system for the closure of duodenal EMR defects. METHODS We reviewed the electronic medical records of patients who underwent EMR for nonampullary duodenal polyps of ≥ 10 mm and prophylactic defect closure with TTS suturing between March 2021 and May 2022 at centers in the USA. We evaluated the rates of delayed bleeding and complete defect closure. RESULTS 36 nonconsecutive patients (61 % women; mean [SD] age, 65 [12] years) underwent EMR of ≥ 10-mm duodenal polyps followed by attempted defect closure with TTS suturing. The mean (SD) lesion size was 29 (19) mm, defect size was 37 (25) mm; eight polyps (22 %) involved > 50 % of the lumen circumference. Complete closure was achieved in all cases (78 % with TTS suturing alone), using a median of one TTS suturing kit. There were no cases of delayed bleeding and no adverse events attributed to application of the TTS suturing device. CONCLUSION Prophylactic closure of nonampullary duodenal EMR defects using TTS suturing resulted in a high rate of complete closure and no delayed bleeding events.

Abstract
OBJECTIVE To evaluate the safety and efficacy of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using a lumen-apposing metal stent (LAMS). BACKGROUND For patients with acute cholecystitis who are poor surgical candidates, EUS-GBD using a LAMS is an important treatment alternative to percutaneous gallbladder drainage. METHODS We conducted a regulatory-compliant, prospective multicenter trial at 7 tertiary referral centers in the United States of America and Belgium. Thirty consecutive patients with mild or moderate acute cholecystitis who were not candidates for cholecystectomy were enrolled between September 2019 and August 2021. Eligible patients had a LAMS placed transmurally with 30 to 60-day indwell if removal was clinically indicated, and 30-day follow-up post-LAMS removal. Endpoints included days until acute cholecystitis resolution, reintervention rate, acute cholecystitis recurrence rate, and procedure-related adverse events (AEs). RESULTS Technical success was 93.3% (28/30) for LAMS placement and 100% for LAMS removal in 19 patients for whom removal was attempted. Five (16.7%) patients required reintervention. Mean time to acute cholecystitis resolution was 1.6±1.5 days. Acute cholecystitis symptoms recurred in 10.0% (3/30) after LAMS removal. Five (16.7%) patients died from unrelated causes. Procedure-related AEs were reported to the FDA in 30.0% (9/30) of patients, including one fatal event 21 days after LAMS removal; however, no AEs were causally related to the LAMS. CONCLUSIONS For selected patients with acute cholecystitis who are at elevated surgical risk, EUS-GBD with LAMS is an alternative to percutaneous gallbladder drainage. It has high technical and clinical success, with low recurrence and an acceptable AE rate. Clinicaltrials.gov, Number: NCT03767881.

A Protocolized Management of Walled-Off Necrosis (WON) Reduces Time to WON Resolution and Improves Outcomes. Clin Gastroenterol Hepatol 2023; 21:2543-2550.e1.

Abstract
BACKGROUND AND AIMS Patients with infected or symptomatic walled-off necrosis (WON) have high morbidity and health care utilization. Despite the recent adoption of nonsurgical treatment approaches, WON management remains nonalgorithmic. We investigated the impact of a protocolized early necrosectomy approach compared with a nonprotocolized, clinician-driven approach on important clinical outcomes. METHODS Records were reviewed for consecutive patients with WON who underwent a protocolized endoscopic drainage with a lumen-apposing metal stent (cases), and for patients with WON treated with a lumen-apposing metal stent at the same tertiary referral center who were not managed according to the protocol (control subjects). The protocol required repeat cross-sectional imaging within 14 days after lumen-apposing metal stent placement, with regularly scheduled endoscopic necrosectomy if WON diameter reduction was <50%. Control patients were treated according to their clinician's preference without an a priori strategy. Inverse probability of treatment weighting-adjusted analysis was used to evaluate the influence of being in the protocolized group on time to resolution. RESULTS A total of 24 cases and 47 control subjects were included. There were no significant differences in baseline characteristics. Although numbers of endoscopies and necrosectomies were similar, cases had lower adverse event rates, shorter intensive care unit stay, and required nutritional support for fewer days. On matched multivariate Cox regression, cases had earlier WON resolution (hazard ratio, 5.73; 95% confidence interval, 2.62-12.5). This was confirmed in the inverse probability of treatment weighting-adjusted analysis (hazard ratio, 3.4; 95% confidence interval, 1.92-6.01). CONCLUSIONS A protocolized strategy resulted in faster WON resolution compared with a discretionary approach without the need for additional therapeutic interventions, and with a better safety profile and decreased health care utilization.

Abstract
BACKGROUND AND AIMS Large colon polyps removed by EMR can be complicated by delayed bleeding. Prophylactic defect clip closure can reduce post-EMR bleeding. Larger defects can be challenging to close using through-the-scope clips (TTSCs), and proximal defects are difficult to reach using over-the-scope techniques. A novel, through-the-scope suturing (TTSS) device allows direct closure of mucosal defects without scope withdrawal. The goal of this study was to evaluate the rate of delayed bleeding after the closure of large colon polyp EMR sites with TTSS. METHODS A multicenter retrospective cohort study was performed involving 13 centers. All defect closure by TTSS after EMR of colon polyps ≥2 cm from January 2021 to February 2022 were included. The primary outcome was rate of delayed bleeding. RESULTS A total of 94 patients (52% female; mean age, 65 years) underwent EMR of predominantly right-sided (n = 62 [66%]) colon polyps (median size, 35 mm; interquartile range, 30-40 mm) followed by defect closure with TTSS during the study period. All defects were successfully closed with TTSS alone (n = 62 [66%]) or with TTSS and TTSCs (n = 32 [34%]), using a median of 1 (interquartile range, 1-1) TTSS system. Delayed bleeding occurred in 3 patients (3.2%), with 2 requiring repeated endoscopic evaluation/treatment (moderate). CONCLUSION TTSS alone or with TTSCs was effective in achieving complete closure of all post-EMR defects, despite a large lesion size. After TTSS closure with or without adjunctive devices, delayed bleeding was seen in 3.2% of cases. Further prospective studies are needed to validate these findings before wider adoption of TTSS for large polypectomy closure.

Abstract
Marginal ulcer (MU) is a potential complication following Roux-en-Y gastric bypass (RYGB), with a mean prevalence of 4.6%. Early identification and prompt intervention are crucial to mitigating further complications. The pathophysiology of MU is complex and involves multiple factors, including smoking, Helicobacter pylori infection, non-steroidal anti-inflammatory drug (NSAID) use, and larger pouch size. Patients with MU may experience acute or chronic abdominal pain. Rarely, they may present with a complication from the ulceration, such as bleeding, perforation, or strictures. Following diagnosis by endoscopy, management of MU typically involves modification of risk factors and medical therapy focused on proton pump inhibitors. In case of complicated ulcers, surgical intervention is often required for the repair of the perforation or resection of the stricture. For recurrent or recalcitrant ulcers, endoscopic coverage of the ulcer bed, resection of the anastomosis, and abdominal or thoracoscopic truncal vagotomy may be considered. This review aims at providing an overview of the etiology, diagnosis, and management of MU after RYGB.

Abstract
BACKGROUND Complete closure of large mucosal defects following colorectal endoscopic submucosal dissection (ESD) with through-the-scope (TTS) clips is oftentimes not possible. We aimed to report our early experience of using a novel TTS suturing system for the closure of large mucosal defects after colorectal ESD. METHODS We performed a retrospective multicenter cohort study of consecutive patients who underwent attempted prophylactic defect closure using the TTS suturing system after colorectal ESD. The primary outcome was technical success in achieving complete defect closure, defined as a < 5 mm residual mucosal defect in the closure line using TTS suturing, with or without adjuvant TTS clips. RESULTS 82 patients with a median defect size of 30 (interquartile range 25-40) mm were included. Technical success was achieved in 92.7 % (n = 76): TTS suturing only in 44 patients (53.7 %) and a combination of TTS suturing to approximate the widest segment followed by complete closure with TTS clips in 32 (39.0 %). Incomplete/partial closure, failure of appropriate TTS suture deployment, and the need for over-the-scope salvage closure methods were observed in 7.3 % (n = 6). One intraprocedural bleed, one delayed bleed, and three intraprocedural perforations were observed. There were no adverse events related to placement of the TTS suture. CONCLUSION The TTS suture system is an effective and safe tool for the closure of large mucosal defects after colorectal ESD and is an alternative when complete closure with TTS clips alone is not possible.

Effect of endoscopic sleeve gastroplasty on gastric emptying, motility and hormones: a comparative prospective study. Gut 2023; 72:1073-1080. [PMID: 36241388 PMCID: PMC10102256 DOI: 10.1136/gutjnl-2022-327816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Accepted: 09/30/2022] [Indexed: 01/19/2023]
Abstract
OBJECTIVE Endoscopic sleeve gastroplasty (ESG) has gained global adoption but our understanding of its mechanism(s) of action and durability of efficacy is limited. We sought to determine changes in gastric emptying (GE), gastric motility (GM), hormones and eating behaviours after ESG. DESIGN A priori-designed single-centre substudy of a large US randomised clinical trial, adults with obesity were randomised to ESG or lifestyle interventions (LS) alone. We measured GE, hormones and weight loss and assessed eating behaviours. In a subset of ESG patients, we assessed GM. The primary outcome was the change in T1/2 (min) at 3 months, and secondary outcomes were changes in weight, GE, GM, hormones and eating behaviours. We used t-test analyses and regression to determine the association between GE and weight loss. RESULTS 36 (ESG=18; LS=18) participated in this substudy. Baseline characteristics were similar between the two groups. At 3 months, T1/2 was delayed in the ESG group (n=17) compared with the LS group (n=17) (152.3±47.3 vs 89.1±27.9; p<0.001). At 12 months, T1/2 remained delayed in the ESG group (n=16) vs control group (n=14) (137±37.4 vs 90.1±23.4; p<0.001). Greater delays in GE at 3 months were associated with greater weight loss. GM was preserved and fasting ghrelin, glucagon-like peptide 1 and polypeptide YY significantly increased 18 months after ESG. CONCLUSION ESG promotes weight loss through several key mechanistic pathways involving GE and hormones while preserving GM. These findings further support clinical adoption of this technique for the management of obesity. TRIAL REGISTRATION NUMBER NCT03406975.

Abstract
OBJECTIVE We evaluated a protocolized endoscopic necrosectomy approach with a lumen-apposing metal stent (LAMS) in patients with large symptomatic walled-off pancreatic necrosis (WON) comprising significant necrotic content, with or without infection. SUMMARY BACKGROUND DATA Randomized trials have shown similar efficacy of endoscopic treatment compared with surgery for infected WON. DESIGN We conducted a regulatory, prospective, multicenter single-arm clinical trial examining the efficacy and safety of endoscopic ultrasound -guided LAMS with protocolized necrosectomy to treat symptomatic WON ≥6 cm in diameter with >30% solid necrosis. After LAMS placement, protocolized WON assessment was conducted and endoscopic necrosectomy was performed for insufficient WON size reduction and persistent symptoms. Patients with radiographic WON resolution to ≤ 3 cm and/or 60-day LAMS indwell had LAMS removal, then 6-month follow-up. Primary endpoints were probability of radiographic resolution by 60 days and procedure-related serious adverse events. RESULTS Forty consecutive patients were enrolled September 2018 to March 2020, of whom 27 (67.5%) were inpatients and 19 (47.5%) had clinical evidence of infection at their index procedure. Mean WON size was 15.0 ± 5.6 cm with mean 53.2% ± 16.7% solid necrosis. Radiographic WON resolution was seen in 97.5% (95% CI, 86.8%, 99.9%) by 60 days, without recurrence in 34 patients with 6-month follow-up data. Mean time to radiographic WON resolution was 34.1 ± 16.8 days. Serious adverse events occurred in 3 patients (7.5%), including sepsis, vancomycin-resistant enterococcal bacteremia and shock, and upper gastrointestinal bleeding. There were no procedure-related deaths. CONCLUSIONS Endoscopic ultrasound-guided drainage with protocolized endoscopic necrosectomy to treat large symptomatic or infected walled-off necrotic pancreatic collections was highly effective and safe.

Abstract
BACKGROUND Lumen-apposing metal stents (LAMS) are an alternative therapeutic option for benign gastrointestinal (GI) tract strictures. Our study aimed to evaluate the safety and efficacy of LAMS for the management of benign GI strictures. METHODS Consecutive patients who underwent a LAMS placement for benign luminal GI strictures at a tertiary care center between January 2014 and July 2021 were reviewed. Primary outcomes included technical success, early clinical success, and adverse events (AEs). Other outcomes included rates of stent migration and re-intervention after LAMS removal. RESULTS One hundred and nine patients who underwent 128 LAMS placements (67.9% female, mean age of 54.3 ± 14.2 years) were included, and 70.6% of the patients had failed prior endoscopic treatments. The majority of strictures (83.5%) were anastomotic, and the most common stricture site was the gastrojejunal anastomosis (65.9%). Technical success was achieved in 100% of procedures, while early clinical success was achieved in 98.4%. The overall stent-related AE rate was 25%. The migration rate was 27.3% (35/128). Of these, five stents were successfully repositioned endoscopically. The median stent dwell time was 119 days [interquartile range (IQR) 68-189 days], and the median follow-up duration was 668.5 days [IQR: 285.5-1441.5 days]. The re-intervention rate after LAMS removal was 58.3%. CONCLUSIONS LAMS is an effective therapeutic option for benign GI strictures, offering high technical and early clinical success. However, the re-intervention rate after LAMS removal was high. In select cases, using LAMS placement as destination therapy with close surveillance is a reasonable option.

Novel classification system for walled-off necrosis: a step toward standardized nomenclature and risk-stratification framework. Gastrointest Endosc 2023; 97:300-308. [PMID: 36208794 DOI: 10.1016/j.gie.2022.09.019] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 09/07/2022] [Accepted: 09/23/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS The optimal therapeutic approach for walled-off necrosis (WON) is not fully understood, given the lack of a validated classification system. We propose a novel and robust classification system based on radiologic and clinical factors to standardize the nomenclature, provide a framework to guide comparative effectiveness trials, and inform the optimal WON interventional approach. METHODS This was a retrospective analysis of patients who underwent endoscopic management of WON by lumen-apposing metal stent placement at a tertiary referral center. Patients were classified according to the proposed QNI classification system: quadrant ("Q"), represented an abdominal quadrant distribution; necrosis ("N"), denoted by the percentage of necrosis of WON; and infection ("I"), denoted as positive blood culture and/or systemic inflammatory response syndrome reaction with a positive WON culture. Two blinded reviewers classified all patients according to the QNI system. Patients were then divided into 2 groups: those with a lower QNI stratification (≤2 quadrants and ≤30% necrosis; group 1) and those with a higher stratification (≥3 quadrants, 2 quadrants with ≥30% necrosis, or 1 quadrant with >60% necrosis and infection; group 2). The primary outcome was mean time to WON resolution. Secondary procedural and clinical outcomes between the groups were compared. RESULTS Seventy-one patients (75% men) were included and stratified by the QNI classification; group 1 comprised 17 patients and group 2, 54 patients. Patients in group 2 had a higher number of necrosectomies, longer hospital stays, and more readmissions. The mean time to resolution was longer in group 2 than in group 1 (79.6 ± 7.76 days vs 48.4 ± 9.22 days, P = .02). The mortality rate was higher in group 2 (15% vs 0%, P = .18). CONCLUSIONS Despite the heterogeneous nature of WON in severe acute pancreatitis, a proposed QNI system may provide a standardized framework for WON classification to inform clinical trials, risk-stratify the disease course, and potentially inform an optimal management approach.

Abstract
Background and study aims Gastric outlet obstruction (GOO) is traditionally managed with surgical gastroenterostomy (surgical-GE) and enteral stenting (ES). Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is now a third option. Large studies assessing their relative risks and benefits with adequate follow-up are lacking. We conducted a comparative analysis of patients who underwent EUS-GE, ES, or surgical-GE for GOO. Patients and methods In this retrospective comparative cohort study, consecutive patients presenting with GOO who underwent EUS-GE, ES, or surgical-GE at two academic institutions were reviewed and independently cross-edited to ensure accurate reporting. The primary outcome was need for reintervention. Secondary outcomes were technical and clinical success, length of hospital stay (LOS), and adverse events (AEs). Results A total of 436 patients (232 EUS-GE, 131 ES, 73 surgical-GE) were included. The median duration of follow-up of the entire cohort was 185.5 days (interquartile range 55.25-454.25 days). The rate of reintervention in the EUS-GE group was lower than in the ES and surgical-GE groups (0.9 %, 12.2 %, and 13.7 %, P < 0.0001). Technical success was achieved in 98.3 %, 99.2 %, and 100 % ( P = 0.58), and clinical success was achieved in 98.3 %, 91.6 %, and 90.4 % ( P < 0.0001) in the EUS-GE, ES, and surgical-GE groups, respectively. The EUS-GE group had a shorter LOS (2 days vs. 3 days vs. 5 days, P < 0.0001) and a lower AE rate than the ES and surgical-GE groups (8.6 % vs. 38.9 % vs. 27.4 %, P < 0.0001). Conclusion This large cohort study demonstrates the safety and palliation durability of EUS-GE as an alternative strategy for GOO palliation in select patients.

Abstract
Background Reports suggest that the rate of adverse events (AEs) post-endoscopic sphincterotomy (ES) to be as high as 10%, with gastrointestinal bleeding being most common after post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. Objective The aim of this study was to characterize the incidence of bleeding in patients with thrombocytopenia following ES. Design Retrospective observational cohort study. Methods Patients with thrombocytopenia (defined as <150,000 platelets/μL) who underwent ES between May 2017 and December 2020 were identified at a tertiary care medical center. The incidence of immediate (intraprocedural oozing >5 min or requiring intervention) or delayed (clinical bleeding with associated hemoglobin drop within 14 days) post-ES bleeding was determined via manual chart review. Results A total of 221 patients with a mean platelet count of 108,000 ± 13,000 platelets/μL underwent ERCP with ES. Immediate bleeding occurred in 11 (5%) patients with no significant drop in hemoglobin or transfusion requirement. Two patients (0.9%), both of whom were noted to have immediate bleeding, also developed delayed bleeding. Presence of malignancy was associated with an increased risk of bleeding (36.4% versus 11.4%, p = 0.037) while platelet count was not. Conclusion In a cohort of patients with thrombocytopenia, rates of immediate and delayed bleeding are similar to previously reported AE rates of ES in the general patient population. Careful attention should be given to patients with a history of active malignancy as well as those who develop immediate bleeding as they appear to be at increased risk for bleeding complications.

Abstract
Background and study aims A percutaneous intragastric trocar (PIT) enables intraluminal use of laparoscopic tools and helps overcome traditional limitations of endoscopy. The aim of this study was to determine the efficacy of using a PIT to perform an anti-reflux stapling procedure. Materials and methods Trocars were placed in four animals and an articulating stapler was used to perform fundoplication under endoscopic guidance. Animals were monitored for 14 days post-procedure. Functional lumen imaging of the esophagogastric junction (EGJ) was performed at baseline, immediately post-intervention, and at 14 days. Results The procedure was successful in all animals who survived to day 14 without distress or significant adverse events. Baseline EGJ distensibility was 5.0 ± 1.2 mm 2 /mmHg, 2.7 ± 0.7 mm 2 /mmHg post-procedurally, and 3.0 ± 0.8mm 2 /mmHg on day 14. Average change in distensibility pre- and post-procedure was -2.3 ± 1.8 mm 2 /mmHg (95 % confidence interval [CI] -0.5 to 5.1, P = 0.08) while change in pre- and day 14 distensibility was -2.0 ± 1.4 mm 2 /mmHg (95 % CI -0.1 to 4.2, P = 0.06). Conclusions An intragastric trocar allows for use of large-diameter laparoscopic instruments to safely and effectively perform endoluminal fundoplication with anti-reflux properties that persist for at least 14 days.

Abstract
OBJECTIVE To describe the clinical, endoscopic, and histologic features in patients with acute esophageal necrosis (AEN). PATIENTS AND METHODS In this retrospective cohort study, patients who were diagnosed as having AEN at Mayo Clinic sites in Minnesota, Florida, and Arizona between January 1, 1996, and January 31, 2021, were included. Data were collected on patient clinical characteristics and endoscopic and pathologic findings. RESULTS The study included 79 patients with AEN with a median (range) age of 64 years (12 to 91 years); 53 (67.1%) were men. Predominant presenting symptoms were hematemesis (49 of 79 [62.0%]), abdominal pain (29 [36.7%]), and melena (20 [25.3%]). Shock was the triggering event for AEN in 49 (62.0%). The 30- and 90-day mortality were 24.0% (19 of 79) and 31.6% (25), respectively. The presence of coexisting infection or bacteremia was significantly associated with 90-day mortality (P<.01). Endoscopically, involvement of the distal third only, distal two-thirds only, and entire esophagus was observed in 31.6% (24 of 76), 39.5% (30), and 29.0% (22), respectively. The length of esophageal involvement correlated with duration of hospitalization (P=.05). The endoscopic appearance of the esophageal mucosa ranged from predominantly white (21 of 44 [47.7%]) to mixed white and black (13 [29.6%]) to predominantly black (10 [22.7%]), and sloughing was present in 18 (40.9%). In the 26 patients with histopathologic findings available for review, 25 (96.1%) had necrosis and/or ulceration with abundant pigmentation. Among the 79 patients, 39 (49.4%) had a follow-up esophagogastroduodenoscopy; 26 of these 39 patients (66.7%) had resolution while 5 had persistent AEN, 4 of whom had improvement. Esophageal strictures developed in 7 of the 39 patients (18.0%). CONCLUSION Acute esophageal necrosis is a serious condition observed in critically ill patients. Its endoscopic appearance can be highly variable. In patients with an unclear diagnosis, esophageal biopsies may be helpful given the characteristic histologic findings.

Abstract
Background and study aims Obtaining quality tissue during ERCP biliary stricture sampling is of paramount importance for a timely diagnosis. While single-operator cholangioscopy (SOC)-guided biopsies have been suggested to be the superior biliary tissue acquisition modality given direct tissue visualization, less is known about the specimen histological quality. We aimed to analyze the specimen quality of SOC biopsies and compare the new generation forceps with prior "legacy" forceps. Patients and methods Patients who underwent SOC from January 2017-August 2021 for biliary sampling were reviewed. In February 2020, the SOC-guided biopsy forceps were changed from legacy SpyBite to the SpyBite Max forceps (max). Specimens were assessed by blinded pathologists for crush artifact (none, mild, or severe) and gross size (greatest dimension in mm). Crush artifact and gross size were compared between the two groups. The diagnostic performance characteristics for cholangiocarcinoma (CCA), were assessed in an exploratory fashion. Results Eighty-one patients (max = 27, legacy = 54) with similar baseline characteristics were included in this study. On blinded pathological assessment, 58 % had crush artifact, without significant differences between the two groups (Max 63 % vs. Legacy 56 %; P = 0.64). A similar mean specimen size was found (max 3 mm vs. legacy 3.2 mm; P = 0.24). The overall prevalence of CCA was 40 %. The sensitivity, specificity, positive predictive value, and negative predictive value of the entire cohort using a combination of cytology, fluorescence in situ hybridization, and SOC-guided biopsies were 78.1 %, 91.8 %, 86.2 %, and 86.5 %, respectively. No difference between legacy or max groups was found. Conclusions A high rate of crush artifact was found in SOC-guided biopsy specimens. Further investigation regarding proper biopsy technique and handling is necessary to increase the diagnostic yield with SOC-guided biopsies.

Abstract
AbstractObesity has been escalating as one of the worst public health epidemics. Conservative therapies including lifestyle modifications and weight loss medications have limited efficacy and long-term sustainability. Bariatric surgeries, although effective, remain underutilized due to their cost, safety concerns, and patient acceptance. In the past two decades, endoscopic bariatric and metabolic therapies (EBMTs) have emerged as safe, effective, and less invasive options for the treatment of obesity and its comorbidities, with recent studies reporting favorable outcomes in terms of weight loss and metabolic parameters. This article reviews the major and newly developed EBMTs, with emphasis on their metabolic effects and potential use in the management of metabolic conditions.

BACKGROUND Endoscopic ultrasound (EUS)-guided main pancreatic duct (PD) access may be used when conventional endoscopic retrograde cholangiopancreatography (ERCP) techniques fail. The use of a percutaneous transluminal angioplasty balloon (PTAB), originally developed for vascular interventions, can be used to facilitate transmural (e.g., transgastric) PD access and to dilate high-grade pancreatic strictures.
AIM To describe the technique, efficacy, and safety of PTABs for EUS-guided PD interventions.
METHODS Patients who underwent EUS with use of a PTAB from March 2011 to August 2021 were retrospectively identified from a tertiary care medical center supply database. PTABs included 3-4 French angioplasty catheters with 3-4 mm balloons designed to use over a 0.018-inch guidewire. The primary outcome was technical success. Secondary outcomes included incidence of adverse events (AEs) and need for early reintervention.
RESULTS A total of 23 patients were identified (48% female, mean age 55.8 years). Chronic pancreatitis was the underlying etiology in 13 (56.5%) patients, surgically altered anatomy (SAA) with stricture in 7 (30.4%), and SAA with post-operative leak in 3 (13.0%). Technical success was achieved in 20 (87%) cases. Overall AE rate was 26% (n = 6). All AEs were mild and included 1 pancreatic duct leak, 2 cases of post-procedure pancreatitis, and 3 admissions for post-procedural pain. No patients required early re-intervention.
CONCLUSION EUS-guided use of PTABs for PD access and/or stricture management is feasible with an acceptable safety profile and can be considered in patients when conventional ERCP cannulation fails.

Efficacy and safety of endoscopic ultrasound-guided gastrojejunostomy in patients with malignant gastric outlet obstruction and ascites. Endosc Int Open 2022; 10:E670-E678. [PMID: 35571468 PMCID: PMC9106441 DOI: 10.1055/a-1797-9318] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Accepted: 02/22/2022] [Indexed: 11/18/2022] Open
Abstract
Background and study aims Endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) is an endoscopic procedure for treating gastric outlet obstruction (GOO). Limited data exist regarding the safety and efficacy of EUS-GJ in patients with malignant GOO with ascites. Thus, we aimed to study the outcomes and safety of EUS-GJ in GOO patients with vs. without ascites. Patients and methods This is a retrospective cohort study of patients with malignant GOO who underwent successful EUS-GJ at a tertiary care academic center. Primary outcomes included the efficacy and safety of EUS-GJ. Secondary outcomes included 30-day readmission, reintervention, and survival utilizing Kaplan-Meier analysis. Results A total of 55 patients (mean age of 67.0 ± 11.3 years, 40.0 % female) who underwent EUS-GJ, of whom 24 had ascites (small in 22, large in 2) were included. Clinical success was achieved in 91.7 % and 93.5 % ( P = 1.00) of patients with and without ascites, respectively. A higher rate of adverse events (AEs) was noted in patients with ascites but this was not statistically significant (37.5 % vs. 19.4 %, P = 0.13). Four patients in the ascites group (16.6 %) developed clinical evidence of peritonitis or sepsis post-EUS-GJ. Eight patients with ascites developed worsening ascites within a month of EUS-GJ. In contrast, only one patient without ascites developed evidence of new ascites. The median survival of patients was not significantly different between the two groups (patients with ascites: 129 days vs. patients without ascites: 180 days, ( P = 0.12). Conclusions The efficacy EUS-GJ in the presence of ascites is promising; however, the safety profile remains concerning given the high rate of AEs, specifically peritonitis and sepsis.
