RESUMEN
Background/Aims: Coaxial placement of double pigtail plastic stents (DPPS) through lumen-apposing metal stents (LAMSs) is commonly performed to reduce the risk of LAMS obstruction, bleeding, and stent migration when used for the drainage of pancreatic fluid collections (PFCs). A systematic review and meta-analysis were performed to compare the outcomes of LAMS alone and LAMS with coaxial DPPS placement in the management of PFCs. Methods: A systematic review was conducted to identify studies comparing LAMS and LAMS/DPPS for PFC drainage. Primary outcomes included the rate of clinical success, overall adverse events (AEs), bleeding, infection, occlusion, and stent migration. The pooled effect size was summarized using a random-effects model and compared between LAMS and LAMS/DPPS by calculating odds ratios (ORs). Results: Nine studies involving 709 patients were identified (338 on LAMS and 371 on LAMS/DPPS). LAMS/DPPS was associated with a reduced risk of stent obstruction (OR, 0.59; p=0.004) and infection (OR, 0.55; p=0.001). No significant differences were observed in clinical success (OR, 0.96; p=0.440), overall AEs (OR, 0.57; p=0.060), bleeding (OR, 0.61; p=0.120), or stent migration (OR, 1.03; p=0.480). Conclusions: Coaxial DPPS for LAMS drainage of PFCs is associated with a reduced risk of stent occlusion and infection; however, no difference was observed in the overall AE rates or bleeding.
RESUMEN
BACKGROUND AND AIMS: Pancreatic fluid collections (PFC) may recur after initial successful endoscopic drainage of walled-off necrosis (WON), most commonly due to disconnected pancreatic duct syndrome (DPDS). The primary aim of this study is to assess the role of magnetic resonance cholangiopancreatography (MRCP) for identifying DPDS to guide appropriate management and prevent PFC recurrence. METHODS: Patients with WON undergoing LAMS drainage of a PFC were retrospectively identified and categorized as those with versus those without MRCP prior to removal of transmural stents. Data on patient demographics, procedural details, cross-sectional imaging, and recurrence rates were collected through chart review. RESULTS: A total of 121 patients with WON were identified, of whom 44 (36.4%) had an MRCP prior to transmural stent removal. In patients without MRCP, 13/77 (16.8%) had PFC recurrence versus 0/44 (0%; p=0.003) in those with MRCP. MRCP identified DPDS in 12 (27.2%) patients, all of whom were managed with indefinite drainage with double-pigtail plastic stents (DPPS) without recurrence. In the group without MRCP, PFCs recurred at a median interval of 284 days (IQR 182-618 days) after transmural stent removal. Among the 13 patients with PFC recurrence, 11 patients (85%) had undiagnosed DPDS detected on subsequent imaging, of whom 9 were subsequently managed with indefinite DPPS, without further PFC recurrence. CONCLUSION: Patients with WON who underwent MRCP prior to transmural stent removal had a lower rate of PFC recurrence largely due to the identification of DPD with appropriate endoscopic management.
RESUMEN
BACKGROUND AND AIMS: Early identification of malignant biliary strictures (MBSs) is challenging, with up to 20% classified as indeterminants after preliminary testing and tissue sampling with endoscopic retrograde cholangiopancreatography. We aimed to evaluate the use of methylated DNA markers (MDMs) from biliary brushings to enhance MBS detection in a prospective cohort. APPROACH: Candidate MDMs were evaluated for their utility in MBS diagnosis through a series of discovery and validation phases. DNA was extracted from biliary brushing samples, quantified, bisulfite-converted, and then subjected to methylation-specific droplet digital polymerase chain reaction. â¯Patients were considered to have no malignancy if the sampling was negative and there was no evidence of malignancy after 1 year or definitive negative surgical histopathology. RESULTS: Fourteen candidate MDMs were evaluated in the discovery phase, with top-performing and new markers evaluated in the technical validation phase. The top 4 MDMs were TWIST1, HOXA1, VSTM2B, and CLEC11A, which individually achieved AUC values of 0.82, 0.81, 0.83, and 0.78, respectively, with sensitivities of 59.4%, 53.1%, 62.5%, and 50.0%, respectively, at high specificities for malignancy of 95.2%-95.3% for the final biologic validation phase. When combined as a panel, the AUC was 0.86, achieving 73.4% sensitivity and 92.9% specificity, which outperformed cytology and fluorescence in situ hybridization (FISH). CONCLUSIONS: The selected MDMs demonstrated improved performance characteristics for the detection of MBS compared to cytology and FISH. Therefore, MDMs should be considered viable candidates for inclusion in diagnostic testing algorithms.
RESUMEN
PURPOSE: Revisional bariatric surgery (RBS) after primary Roux-en-Y gastric bypass (RYGB) is indicated for the efficient management of specific complications such as bile reflux. Published literature on this topic remains scarce as we aim to evaluate the long-term outcomes (10 years) of RBS for bile reflux after RYGB. MATERIAL AND METHODS: We conducted a single-center retrospective study of patients who underwent primary RYGB complicated by bile reflux and had RBS between 2008 and 2023. Our cohort was divided into two groups based on the etiology of bile reflux. Long-term surgical outcomes and nutritional status were reported and compared between the groups. RESULTS: A total of 41 patients (100% primary RYGB; 90.2% female, 97.6% white) were included. 56.1% (n = 23) of patients underwent Roux limb lengthening and the remaining 43.9% (n = 18) had a gastrogastric fistula takedown, with no significant differences in terms of intraoperative complications, estimated blood loss (p = 0.616), length of hospital stay (p = 0.099), and postoperative complications between the two groups. Long-term resolution of obesity-related medical conditions was demonstrated for all the evaluated comorbidities. Lastly, there was no reported mortality, bile reflux recurrence, or micro- and macro-nutrient deficiencies over the total follow-up period of 10 years. CONCLUSION: In our cohort, RBS after a primary RYGB for bile reflux management demonstrated safe and efficient short- and long-term surgical outcomes without any reported bile reflux recurrence or mortality. Adequate supplementation and close patient follow-up remain essential to decrease the morbidity and mortality associated with RBS as further studies are required to support our findings.

Background: To evaluate the weight loss outcomes of the large US cohort of patients undergoing endoscopic sleeve gastroplasty (ESG) with or without concomitant anti-obesity (AOM) use. Methods: We performed a retrospective analysis of adult patients who underwent ESG from seven different sites, from January 1, 2020 to November 30, 2022. Percent total body weight loss (%TBWL) and %excess weight loss (%EWL) were calculated based on baseline weight at the procedure. Medication use was considered if the subject received a prescribed AOM during the study period. SPSS (version 29.0) was used for statistical analyses. Results: A total of 1506 patients were included (1359 (90.2 %) no AOM use and 147 (9.8 %) AOM use). Patients who were on an active AOM at the time of the procedure had a significantly lower TBWL% as compared to patients not on AOMs at 6 months. At the 24-month visit, patients who were prescribed AOMs after the 12-month visit had a significantly higher TBWL% and EWL% as compared to patients who were on active AOM at the time of the procedure. There was no significant difference between classes of medications at any time point, however, patients on a GLP-1RA had a trend towards improved weight loss at 18 and 24 months. Conclusion: In this large, real-world cohort of patients from the United States, data signal that with the use of pharmacotherapy at the appropriate time, patients can achieve optimal results.
RESUMEN
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.
RESUMEN
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.
RESUMEN
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.
Use of individualized metabolic surgery score in endoscopic sleeve gastroplasty Why was the study done? Endoscopic sleeve gastroplasty (ESG) is effective and safe as a treatment for obesity and has also shown improvement in diabetes in previous studies. However, there is no data showing the rates of diabetes remission after this procedure and no measures to predict this outcome. This study uses the individualized metabolic score (IMS) to predict diabetes remission after ESG. What did the researchers do? They analyzed a sample of patients who had undergone ESG, and evaluated the change in their diabetes parameters at 1 year compared to baseline, and then correlated this with their calculated baseline IMS score. What did the researchers find? Patients with a higher IMS score, representing more severe disease, were less likely to have an improvement in their diabetes after ESG. What do the findings mean? ESG can be an effective treatment option for patients with obesity and early-stage diabetes.
RESUMEN
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.
RESUMEN
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.

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.

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.

INTRODUCTION: Inadequate bowel preparation can result in decreased diagnostic accuracy and therapeutic safety of colonoscopy for colon cancer screening. The Boston Bowel Preparation Scale (BBPS) has been used to assess the quality of bowel preparation. Glucagon-like peptide-1 receptor agonists (GLP-1RA) are commonly used medications for diabetes mellitus and obesity that are known to delay gastrointestinal motility. We hypothesized that the use of GLP-1RA would be associated with decreased quality of bowel preparation. METHODS: We performed a retrospective cohort study of patients who underwent screening or surveillance colonoscopy at a large academic medical center between December 2021 and December 2022. We included patients taking any GLP-1RA for diabetes or obesity during colonoscopy defined as our cases, and patients who were prescribed GLP-1RA at one point but not within 3 months of colonoscopy defined as our controls. We excluded patients on any promotility or antimotility agents and those without BBPS recorded on their procedure report. Independent t test assessed statistical differences in the case and control groups to compare the quality of bowel preparation for continuous variables, and the χ 2 test was used for categorical variables. Multivariate linear regression including diabetes as a covariate was also performed for continuous variables, and multivariate logistic regression was performed for categorical variables. RESULTS: A total of 446 patients were included in the study, comprising 265 (59%) cases and 181 controls (41%). There were no statistically significant differences between groups at baseline except for the diagnosis of diabetes ( P = 0.001) with a higher proportion of patients with diabetes in the cases. The mean BBPS was significantly higher in controls (7.0 ± 1.9 vs 7.5 ± 2.4, P = 0.046) when controlling for diabetes. The percentage of patients with a total BBPS score of <5 was significantly higher in cases (15.5% vs 6.6%, P = 0.01). The proportion of patients who required a repeat colonoscopy due to poor bowel preparation was also significantly higher in cases (18.9% vs 11.1%, P = 0.041). DISCUSSION: The use of GLP-1RA was associated with a statistically significantly lower quality of bowel preparation, with additional clinical significance given a notable difference in the need for a repeat colonoscopy. It will be essential to understand the cumulative effect of medications that may delay gastric emptying on the quality of bowel preparation to better understand the appropriate measures and counseling that need to be taken before undergoing outpatient colonoscopies.
RESUMEN
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.

INTRODUCTION: Gastrojejunal anastomosis (GJA) dilation is an independent predictor of weight regain (WR) after Roux-en-Y gastric bypass (RYGB). However, the role of planimetric measurements in this context remains unknown. METHODS: This is a retrospective cohort study including adult RYGB patients who underwent a diagnostic endoscopy with Endoflip assessment of the GJA. We excluded patients in the early postoperative period and those with abnormal endoscopic findings (marginal ulcers and gastro-gastric fistulas). RESULTS: Thirty-four patients were initially included. Endoscopic GJA diameter had a moderate positive correlation with WR (r=+0.438, p=0.011). However, after excluding the 7 patients with GJA> 30 mm, there was no significant correlation. There was a moderate agreement between the EndoFLIP-GJA diameter at 60mL and endoscopic diameter (ICC=0.576, p=0.049). The distensibility index (DI) showed a consistent moderate negative correlation with WR. Considering the maximum DI at 40 ml, we found a cutoff of DI = 7 mm2/mmHg that split the sample in two significantly different populations in terms of WR (67.4% vs. 43.2%, p=0.04). CONCLUSION: Visual estimation of the GJA diameter correlates with EndoFLIP at 60mL. In the subset of patients with GJA ≤ 30 mm, more distensible GJAs are associated with lower rates of WR. Larger studies are needed to confirm this correlation and to validate its utility for clinical management.

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.
RESUMEN
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.
RESUMEN
BACKGROUND AND AIMS: Data on how to teach endosonographers needle-based confocal laser endomicroscopy (nCLE)-guided histologic diagnosis of pancreatic cystic lesions (PCLs) are limited. Hence, we developed and tested a structured educational program to train early-career endosonographers in nCLE-guided diagnosis of PCLs. METHODS: Twenty-one early-career nCLE-naïve endosonographers watched a teaching module outlining nCLE criteria for diagnosing PCLs. Participants then reviewed 80 high-yield nCLE videos, recorded diagnoses, and received expert feedback (phase 1). Observers were then randomized to a refresher feedback session or self-learning at 4 weeks. Eight weeks after training, participants independently assessed the same 80 nCLE videos without feedback and provided histologic predictions (phase 2). Diagnostic performance of nCLE to differentiate mucinous versus nonmucinous PCLs and to diagnose specific subtypes were analyzed using histopathology as the criterion standard. Learning curves were determined using cumulative sum analysis. RESULTS: Accuracy and diagnostic confidence for differentiating mucinous versus nonmucinous PCLs improved as endosonographers progressed through nCLE videos in phase 1 (P < .001). Similar trends were observed with the diagnosis of PCL subtypes. Most participants achieved competency interpreting nCLE, requiring a median of 38 assessments (range, 9-67). During phase 2, participants independently differentiated PCLs with high accuracy (89%), high confidence (83%), and substantial interobserver agreement (κ = .63). Accuracy for nCLE-guided PCL subtype diagnoses ranged from 82% to 96%. The learned nCLE skills did not deteriorate at 8 weeks and were not impacted by a refresher session. CONCLUSIONS: We developed a practical, effective, and durable educational intervention to train early-career endosonographers in nCLE-guided diagnosis of PCLs.

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 (Pâ<â0.001 for POSE 2.0; Pâ=â0.24 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.

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.
