Abstract
BACKGROUND Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is frequently used to obtain core samples of solid lesions. Here, we describe and evaluate a novel hydrostatic stylet (HS) technique designed to optimize core sample acquisition, reporting diagnostic yield, efficacy, and safety relative to the conventional stylet slow-pull (SP) technique. METHODS A novel HS technique was developed and validated retrospectively. Consecutive patients who underwent EUS-FNB with core biopsy of solid lesions through either the HS or SP technique between January 2020 and April 2022 were included. Exclusion criteria included cystic lesions, nonlesional liver biopsies, and specimens sent for cytologic analysis only. Patient and lesion characteristics, number of passes, sample adequacy, and adverse events were compared between the two techniques. RESULTS A total of 272 patients were included with 138 in the HS group and 134 in the SP group. Lesion size and anatomic distribution were similar in both groups. Compared with the SP approach, the HS technique demonstrated significantly higher sample adequacy (97.8% vs 83.6%, P < 0.001), higher sensitivity (97.1% vs 89.7%, P = 0.03), and lower mean number of passes (1.2 vs 3.3, P < 0.001). Rates and severity of adverse events in the HS group were comparable to the SP group and existing literature. Similar associations were observed in pancreatic and nonpancreatic lesion subanalyses. CONCLUSIONS The novel HS technique demonstrated excellent biopsy sample adequacy and diagnostic yield while requiring fewer passes to obtain diagnostic specimens compared with a conventional EUS-FNB approach. Further prospective evaluation is needed to confirm these pilot findings and optimize EUS-FNB acquisition techniques.

Abstract
BACKGROUND AND AIMS The application of endoscopic suturing has revolutionized defect closures. Conventional over-the-scope suturing necessitates removal of the scope, placement of the device, and reinsertion. A single channel, single sequence, through-the-scope suturing device has been developed to improve this process. This study aims to describe the efficacy, feasibility, and safety of a through-the-scope suturing device for gastrointestinal defect closure. METHODS This was a retrospective multicenter study involving 9 centers of consecutive adult patients who underwent suturing using the X-Tack Endoscopic HeliX Tacking System (Apollo Endosurgery). The primary outcomes were technical success and long-term clinical success. Secondary outcomes included adverse events, recurrence, and reintervention rates. RESULTS In all, 56 patients (mean age 53.8, 33 women) were included. Suturing indications included fistula repair (n=22), leak repair (n=7), polypectomy defect closure (n=12), peroral endoscopic myotomy (POEM) site closure (n=7), perforation repair (n=6), and ulcers (n=2). Patients were followed at a mean duration of 74 days. Overall technical and long-term clinical success rates were 92.9% and 75%, respectively. Both technical and clinical success rates were 100% for polypectomies, POEM-site closures, and ulcers. Success rates were lower for the repair of fistulas (95.5% technical, 54.5% clinical), leaks (57.1%, 28.6%), and perforations (100%, 66.7%). No immediate adverse events were noted. CONCLUSION This novel, through-the-scope endoscopic suturing system, is a safe and feasible method to repair defects that are ≤3 cm. The efficacy of this device may be better suited for superficial defects as opposed to full-thickness defects. Larger defects will need more sutures and probably a double closure technique to provide a reinforcement layer.

Abstract
Background and study aims Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is an emerging procedure that lacks technical standardization with limited adoption beyond expert centers. We surveyed high-volume endosonographers about the technical aspects of EUS-GE to describe how the procedure is currently performed at expert centers and identify targets for standardization. Methods Invitations to complete an electronic survey were distributed to 21 expert EUS practitioners at 19 U.S. centers. Respondents were surveyed about technical aspects of EUS-GE, indications, efficacy, safety, and attitudes toward the procedure. Results All 21 (100%) invited expert endoscopists completed the survey. Nine (42.9%) reported performing >10 EUS-GEs in the last 12 months. About half (47.6%, 10/21) puncture the target loop prior to lumen-apposing metal stent (LAMS) introduction, most often to confirm the loop is jejunum. No respondents reported guidewire placement prior to LAMS introduction. Most (71.4%, 15/21) do not use a guidewire at any time, while 28.6% (6/21) reported wire placement after distal flange deployment to secure the tract during apposition. Eight (38.1%, 8/21) reported at least one major adverse event, most commonly intraperitoneal LAMS deployment (87.5%, 7/8). Factors most often reported as advantageous for EUS-GE over enteral stenting included lack of papilla interference (33.3%, 7/21) and decreased occlusion risk (23.8%, 5/21). Conclusions Significant variation in performance technique for EUS-GE exists among expert US endoscopists, which may hinder widespread adoption and contribute to inconsistencies in reported patient outcomes. The granularity provided by these survey results may identify areas to focus standardization efforts and guide future studies on developing an ideal EUS-GE protocol.

Abstract
BACKGROUND AND AIMS No studies have evaluated trainees' outcomes when learning ERCP with patients in the supine and prone positions simultaneously. We aimed to assess whether patient position impacts procedural outcomes and learning curve. METHODS We prospectively evaluated patients undergoing ERCP by a supervised advanced endoscopy trainee (AET) at a tertiary care center. Adult patients with native papillae were included. The AET was universally given 5 attempts per cannulation. Outcomes were evaluated quarterly. RESULTS Successful cannulation was achieved in 44 supine (69%) and 17 prone (68%) patients (P = .95). Although mean time to reach the papilla was shorter in the supine patient position, time to biliary cannulation (7.8 vs 9.4 minutes, P = .53) and number of attempts were similar. A stepwise increase was seen in cannulation rates throughout the academic year (P < .01) and increased more in supine patients (P = .01). Procedure and total room times were shorter in supine patients. CONCLUSIONS Shorter procedure and room turnover times and a comparable cannulation rate were found for supine versus prone ERCP.

Abstract
BACKGROUND We conducted this study to compare the weight loss outcome of intragastric balloons (IGBs) in conjunction with pharmacotherapy vs IGB and intensive lifestyle changes alone. METHODS This was a multicenter, non-randomized, retrospective study involving 4 academic hospitals. Patients underwent IGB placement with or without concomitant anti-obesity pharmacotherapy. The primary outcome was percent total weight loss (TBWL) after IGB placement at 6 and 12 months. RESULTS This study included 102 patients, with 23 patients (mean age 46.6 years, 82.6% female) treated with IGB/pharmacotherapy and 79 patients (mean age 46.0 years, 88.6% female) treated with IGB/lifestyle modifications. Patients had a 100% follow-up rate at 6 and 12 months. At 6 months following IGB placement, both groups achieved a similar %TBWL. At 12 months, %TBWL was greater in the IGB/pharmacotherapy group (12.6% ± 1.2 vs 9.7% ± 0.7, P = .04). 65.2% of patients achieved ≥10% TBWL at 12 months in the IGB/pharmacotherapy group, compared to 38.0% in the IGB/lifestyle group (P < .05). The proportion of patients that achieved ≥15% weight loss at 12 months was also significantly different between the IGB/pharmacotherapy and IGB/lifestyle groups (30.4% vs 20.3%, P < .05). DISCUSSION IGB with concomitant use of pharmacotherapy did not improve weight loss while the IGB was in place compared to IGB and lifestyle changes. However, patients receiving IGB with pharmacotherapy did have greater weight loss and diminished weight regain after balloon removal compared to those receiving just IGB and lifestyle changes.

Abstract
BACKGROUND & AIMS Endoscopic submucosal dissection (ESD) is a widely accepted treatment option for superficial gastric neoplasia in Asia, but there are few data on outcomes of gastric ESD from North America. We aimed to evaluate the safety and efficacy of gastric ESD in North America. METHODS We analyzed data from 347 patients who underwent gastric ESD at 25 centers, from 2010 through 2019. We collected data on patient demographics, lesion characteristics, procedure details and related adverse events, treatment outcomes, local recurrence, and vital status at the last follow up. For the 277 patients with available follow-up data, the median interval between initial ESD and last clinical or endoscopic evaluation was 364 days. The primary endpoint was the rate of en bloc and R0 resection. Secondary outcomes included curative resection, rates of adverse events and recurrence, and gastric cancer-related death. RESULTS Ninety patients (26%) had low-grade adenomas or dysplasia, 82 patients (24%) had high-grade dysplasia, 139 patients (40%) had early gastric cancer, and 36 patients (10%) had neuroendocrine tumors. Proportions of en bloc and R0 resection for all lesions were 92%/82%, for early gastric cancers were 94%/75%, for adenomas and low-grade dysplasia were 93%/ 92%, for high-grade dysplasia were 89%/ 87%, and for neuroendocrine tumors were 92%/75%. Intraprocedural perforation occurred in 6.6% of patients; 82% of these were treated successfully with endoscopic therapy. Delayed bleeding occurred in 2.6% of patients. No delayed perforation or procedure-related deaths were observed. There were local recurrences in 3.9% of cases; all occurred after non-curative ESD resection. Metachronous lesions were identified in 14 patients (6.9%). One of 277 patients with clinical follow up died of metachronous gastric cancer that occurred 2.5 years after the initial ESD. CONCLUSIONS ESD is a highly effective treatment for superficial gastric neoplasia and should be considered as a viable option for patients in North America. The risk of local recurrence is low and occurs exclusively after non-curative resection. Careful endoscopic surveillance is necessary to identify and treat metachronous lesions.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is often unsuccessful in patients with duodenal stenosis or malignant ampullary infiltration. While endoscopic ultrasound-guided biliary drainage (EUS-BD) has been proposed as an alternative, EUS-guided gallbladder drainage (EUS-GBD) is an attractive option when both approaches fail. We aimed to assess the effectiveness and safety of EUS-GBD as rescue therapy for malignant distal bile duct obstruction. METHODS A multicenter retrospective study was performed on patients with unresectable malignant distal bile duct obstruction who underwent EUS-GBD between 2014 and 2019 after unsuccessful ERCP and EUS-BD. Clinical success was defined as a decrease in serum bilirubin of > 50 % within 2 weeks. RESULTS 28 patients were included, with a lumen-apposing metal stent used in 26 (93 %) and a self-expandable metal stent in two (7 %). The technical success rate was 100 %. The clinical success rate was 93 %, with an improvement in bilirubin (7.3 [SD 5.4] pre-procedure vs. 2.8 [SD 1.1] post-procedure; P = 0.001). Delayed adverse events included food impaction of the stent (n = 3), with a further two patients developing cholecystitis and bleeding. CONCLUSION This study demonstrates the feasibility of gallbladder drainage to relieve malignant distal bile duct obstruction in patients with failed ERCP and EUS-BD.

Abstract
Background and study aims The goal of this study was to assess surgical resection (SR) of early gastric cancer (EGC) fitting Japanese Gastric Cancer Association (JGCA) endoscopic resection (ER) criteria. Patients and methods We analyzed EGC data from the national Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015. Results A total of 2219 EGC cases were identified (1074 T1a and 1145 T1b). Of them, 409 met absolute criteria, 219 met expanded 1, 529 expanded 2, and 229 expanded 3. 259 lesions were treated endoscopically while 1007 were surgically resected (20.5 % vs 79.5 %, P = 0.0001). Temporal analysis showed that the frequency of ER steadily increased while SR proportionally decreased during the study period. Cox proportion regression analysis adjusting for confound variables (including age, gender, and race) showed no significant difference in the risk of mortality following either surgery or endoscopy. Conclusions EGC can be safely treated with ER. However, EGC meeting JGCA ER criteria is largely treated with SR in the United States.

Abstract
Background and study aims The rate of gastroesophageal reflux disease (GERD) after per oral endoscopic myotomy (POEM) is concerning. Endoscopic anti-reflux methods, such as Trans Oral Incisionless Fundoplication (TIF), are crucial for the long-term success of POEM, especially if they can be performed in the same session. Methods We completed a proof-of-concept canine pilot study (n = 6) to assess safety and feasibility of POEM and TIF in a single session (POEM-TIF). Subsequently, POEM-TIF was also performed in patients with achalasia (n = 5). Herein, we report on the safety, technical and clinical success of the first-in-human cases with symptom follow-up at 1, 3 and 6 months and pH testing at 6 months. Results POEM was completed successfully in six canines (3 anterior and 3 posterior myotomies), followed by TIF in the same session. Necropsy and extensive testing demonstrated no evidence of mucosal injury and no leaks. The reconstructed valve was 220 to 240 degrees, 3 to 4 cm in length, and resulted in concomitant esophageal lengthening (2-5 cm). Using similar principles, the first-in-human cases were performed without intraprocedural or delayed adverse events. pH testing at 6 months showed that four of five patients had no evidence of GERD (DeMeester > 14.72), and in one case, there was evidence of esophagitis. Conclusions Single session POEM-TIF appears to be safe and feasible. Early clinical human data suggests that it may be able to reduce post POEM GERD, however the additional secondary benefits such as lengthening and straightening of the esophagus, may prove to be equally important for the long-term success of POEM.

Abstract
Background and study aims The coronavirus disease 2019 (COVID-19), and measures taken to mitigate its impact, have profoundly affected the clinical care of gastroenterology patients and the work of endoscopy units. We aimed to describe the clinical care delivered by gastroenterologists and the type of procedures performed during the early to peak period of the pandemic. Methods Endoscopy leaders in the New York region were invited to participate in an electronic survey describing operations and clinical service. Surveys were distributed on April 7, 2020 and responses were collected over the following week. A follow-up survey was distributed on April 20, 2020. Participants were asked to report procedure volumes and patient characteristics, as well protocols for staffing and testing for COVID-19. Results Eleven large academic endoscopy units in the New York City region responded to the survey, representing every major hospital system. COVID patients occupied an average of 54.5 % (18 - 84 %) of hospital beds at the time of survey completion, with 14.5 % (2 %-23 %) of COVID patients requiring intensive care. Endoscopy procedure volume and the number of physicians performing procedures declined by 90 % (66 %-98 %) and 84.5 % (50 %-97 %) respectively following introduction of restricted practice. During this period the most common procedures were EGDs (7.9/unit/week; 88 % for bleeding; the remainder for foreign body and feeding tube placement); ERCPs (5/unit/week; for cholangitis in 67 % and obstructive jaundice in 20 %); Colonoscopies (4/unit/week for bleeding in 77 % or colitis in 23 %) and least common were EUS (3/unit/week for tumor biopsies). Of the sites, 44 % performed pre-procedure COVID testing and the proportion of COVID-positive patients undergoing procedures was 4.6 % in the first 2 weeks and up to 19.6 % in the subsequent 2 weeks. The majority of COVID-positive patients undergoing procedures underwent EGD (30.6 % COVID +) and ERCP (10.2 % COVID +). Conclusions COVID-19 has profoundly impacted the operation of endoscopy units in the New York region. Our data show the impact of a restricted emergency practice on endoscopy volumes and the proportion of expected COVID positive cases during the peak time of the pandemic.

Abstract
Background and study aims The Full-Thickness Resection Device (FTRD) provides a novel treatment option for lesions not amenable to conventional endoscopic resection techniques. There are limited data on the efficacy and safety of FTRD for resection of upper gastrointestinal tract (GIT) lesions. Patients and methods This was an international multicenter retrospective study, including patients who had an endoscopic resection of an upper GIT lesion using the FTRD between January 2017 and February 2019. Results Fifty-six patients from 13 centers were included. The most common lesions were mesenchymal neoplasms (n = 23, 41 %), adenomas (n = 7, 13 %), and hamartomas (n = 6, 11 %). Eighty-four percent of lesions were located in the stomach, and 14 % in the duodenum. The average size of lesions was 14 mm (range 3 to 33 mm). Deployment of the FTRD was technically successful in 93 % of patients (n = 52) leading to complete and partial resection in 43 (77 %) and 9 (16 %) patients, respectively. Overall, the FTRD led to negative histological margins (R0 resection) in 38 (68 %) of patients. A total of 12 (21 %) mild or moderate adverse events (AEs) were reported. Follow-up endoscopy was performed in 31 patients (55 %), on average 88 days after the procedure (IQR 68-138 days). Of these, 30 patients (97 %) did not have any residual or recurrent lesion on endoscopic examination and biopsy, with residual adenoma in one patient (3 %). Conclusions Our results suggest a high technical success rate and an acceptable histologically complete resection rate, with a low risk of AEs and early recurrence for FTRD resection of upper GIT lesions.

Abstract
The COVID-19 pandemic seemingly is peaking now in New York City and has triggered significant changes to the standard management of gastrointestinal diseases. Priorities such as minimizing viral transmission, preserving personal protective equipment, and freeing hospital beds have driven unconventional approaches to managing gastroenterology (GI) patients. Conversion of endoscopy units to COVID units and redeployment of GI fellows and faculty has profoundly changed the profile of most GI services. Meanwhile, consult and procedural volumes have been reduced drastically. In this review, we share our collective experiences regarding how we have changed our practice of medicine in response to the COVID surge. Although we review our management of specific consults and conditions, the overarching theme focuses primarily on noninvasive measures and maximizing medical therapies. Endoscopic procedures have been reserved for those timely interventions that are most likely to be therapeutic. The role of multidisciplinary discussion, although always important, now has become critical. The support of our faculty and trainees remains essential. Local leadership can encourage well-being by frequent team check-ins and by fostering trainee development through remote learning. Advancing a clear vision and a transparent process for how to organize and triage care in the recovery phase will allow for a smooth transition to our new normal.

Abstract
Abstract
Background and study aims With newer imaging modalities, indications for use of endoscopic retrograde cholangiopancreatography (ERCP) have changed in the last decade. Despite advances in ERCP, paucity in recent literature regarding utilization and outcomes of ERCP exists. Thus, the aim of this study was to assess the inpatient use of ERCP, outcomes, and most common indications.
Patients and methods Retrospective-cohort study using the Nationwide Inpatient Sample 2007–2016. All patients with ICD9–10CM procedural codes for ERCP were included. The primary outcome was the use of ERCP. Secondary outcomes included determining procedural specifics (stenting, sphincterotomy and dilation), complications (post-ERCP pancreatitis [PEP], bile duct perforation), hospital length of stay, total hospital costs and charges. Multivariate regression analysis was used to adjust for confounders.
Results A total of 1,606,850 patients underwent inpatient ERCP. The mean age was 59 years (60 % female). The total number of ERCPs increased over the last decade. Patients undergoing ERCP in 2016 had greater odds of undergoing bile duct stent placement, pancreatic duct (PD) stenting, biliary dilation, pancreatic sphincterotomy, PEP and biliary perforation. Inpatient mortality decreased. Hospital charges increased, while length of stay (LOS) decreased.
Conclusions The number of ERCPs increased in the past decade. Odds of therapeutic interventions and complications increased. The most common principal diagnoses were choledocholithiasis and gallstone-related AP. Hence, physicians must be aware to promptly diagnose and treat complications. These findings may reflect the increased case complexity and fact that ERCP continues to evolve into an increasingly interventional tool, contrasting from its former role as a predominantly diagnostic and gallstone extraction tool.

Abstract
INTRODUCTION AND AIM Endoscopic submucosal dissection (ESD) for early gastric cancer is highly effective and well established. Performing ESD in the surgically altered stomach (SAS) is challenging. The aim of this meta-analysis is to assess the safety and efficacy of ESD for patients with early neoplastic lesions occurring in the SAS with a subgroup analysis of lesions occurring on the suture line compared to non-suture line lesions and outcomes in the remnant stomach compared to the gastric tube. METHODS We performed a literature search of the PubMed, Embase, and CINAHL electronic databases from January 2000 to November 2017 for articles reporting the safety and efficacy of ESD in the surgically altered stomach. SAS was defined as the remnant stomach following gastrectomy and gastric tube following esophagectomy. Meta-analysis was performed using Review Manager version 5.3 software. RESULTS A total of 21 articles, with 903 lesions occurring in the remnant stomach or gastric tube, were included in this study. There was no significant difference between en bloc (RR 0.99, 95% CI 0.91-1.08), curative resection (RR 1.03, 95% CI 0.84-1.26), or bleeding rates (RR 1.40, 95% CI 0.18-10.72) between lesions in the remnant stomach and gastric tube. However, perforation was significantly higher in the gastric tube (RR 5.19, 95% 1.27-21.25). Suture line lesions had a significantly higher risk of perforation (RR 4.55, 95% CI 2.13-9.74). CONCLUSION ESD for early neoplastic lesions occurring in the SAS is a safe and efficacious with similar en bloc and curative resection rates compared to the anatomically normal stomach. ESD for lesions on the suture line or in the gastric tube is associated with an increased risk of perforation which can be managed endoscopically.

Abstract
BACKGROUND AND STUDY AIMS Current endoscopic therapies for gastroesophageal reflux disorder (GERD) are limited by technical complexity, and/or cost. We sought to evaluate the success of a novel resection and plication (RAP) anti-reflux procedure. PATIENTS AND METHODS RAP was performed on 10 patients with GERD refractory to proton pump inhibitor (PPI) therapy. RAP consists of semi-circumferential mucosectomy along with full-thickness plication of the lower esophageal sphincter (LES) and cardia. We assessed the technical success and safety as well as followed GERD-Health Related Quality of Life (GERD-HRQL) scores and medication usage. RESULTS All patients underwent RAP without adverse events and were discharged on the same day. Only half of the patients required general anesthesia. Follow-up ranged from 5 to 24 months (median 9 months) and all patients had a significant improvement in their GERD-HRQL scores ( P < 0.0001, 95 % CI 19.3 - 25.3). 8 of 10 eliminated their daily PPI dependence. CONCLUSIONS The RAP method has potential as an effective anti-reflux option. Its main advantages include a short procedure time, simple approach using readily available equipment, and possible avoidance of general anesthesia.

Abstract
BACKGROUND There is no standard nor widely accepted way of reporting outcomes of treatment of biliary injuries. This hinders comparison of results among approaches and among centers. This paper presents a proposal to standardize terminology and reporting of results of treating biliary injuries. METHODS The proposal was developed by an international group of surgeons, biliary endoscopists and interventional radiologists. The method is based on the concept of "patency" and is similar to the approach used to create reporting standards for arteriovenous hemodialysis access. RESULTS The group considered definitions and gradings under the following headings: Definition of Patency, Definition of Index Treatment Periods, Grading of Severity of Biliary Injury, Grading of Patency, Metrics, Comparison of Surgical to Non Surgical Treatments and Presentation of Case Series. CONCLUSIONS A standard procedure for reporting outcomes of treating biliary injuries has been produced. It is applicable to presenting results of treatment by surgery, endoscopy, and interventional radiology.

Abstract
Background and study aims Data on clinical outcomes of endoscopic drainage of debris-free pseudocysts (PDF) versus pseudocysts containing solid debris (PSD) are very limited. The aims of this study were to compare treatment outcomes between patients with PDF vs. PSD undergoing endoscopic ultrasound (EUS)-guided drainage via transmural stents. Patients and methods Retrospective review of 142 consecutive patients with pseudocysts who underwent EUS-guided transmural drainage (TM) from 2008 to 2014 at 15 academic centers in the United States. Main outcome measures included TM technical success, treatment outcomes (symptomatic and radiologic resolution), need for endoscopic re-intervention at follow-up, and adverse events (AEs). Results TM was performed in 90 patients with PDF and 52 with PSD. Technical success: PDF 87 (96.7 %) vs. PSD 51 (98.1 %). There was no difference in the rates for endoscopic re-intervention (5.5 % in PDF vs. 11.5 % in PSD; P = 0.33) or AEs (12.2 % in PDF vs. 19.2 % in PSD; P = 0.33). Median long-term follow-up after stent removal was 297 days (interquartile range [IQR]: 59 - 424 days) for PDF and 326 days (IQR: 180 - 448 days) for PSD (P = 0.88). There was a higher rate of short-term radiologic resolution of PDF (45; 66.2 %) vs. PSD (21; 51.2 %) (OR = 0.30; 95 % CI: 0.13 - 0.72; P = 0.009). There was no difference in long-term symptomatic resolution (PDF: 70.4 % vs. PSD: 66.7 %; P = 0.72) or radiologic resolution (PDF: 68.9 % vs. PSD: 78.6 %; P = 0.72) Conclusions There was no difference in need for endoscopic re-intervention, AEs or long-term treatment outcomes in patients with PDF vs. PSD undergoing EUS-guided drainage with transmural stents. Based on these results, the presence of solid debris in pancreatic fluid collections does not appear to be associated with a poorer outcome.

Abstract
BACKGROUND & AIMS Endoscopic ultrasound-guided transmural drainage and necrosectomy have become the standard treatment for patients with pancreatic walled-off necrosis (WON). Lumen-apposing metal stents (LAMS) have shown success in the management of pancreatic fluid collections. However, there are few data on their specific roles in management of WON. We investigated the efficacy and safety of LAMS in treatment of WON. METHODS We performed a retrospective multicenter case series of 124 patients with WON who underwent endoscopic transmural drainage by using LAMS at 17 tertiary care centers from January 2014 through May 2015. Patients underwent endoscopic ultrasound-guided cystogastrostomy or cystoenterostomy with placement of an LAMS into the WON collection. At the discretion of the endoscopist, we performed direct endoscopic necrosectomy, irrigation with hydrogen peroxide, and/or nasocystic drain placement. We performed endoscopic retrograde cholangiopancreatography with pancreatic duct stent placement when indicated. Concomitant therapies included direct endoscopic debridement (n = 78), pancreatic duct stent placement for leak (n = 19), hydrogen peroxide-assisted necrosectomy (n = 38), and nasocystic irrigation (n = 22). We collected data for a median time of 4 months (range, 1-34 months) after the LAMS placement. The primary outcomes were rates of technical success (successful placement of the LAMS), clinical success (resolution of WON, on the basis of image analysis, without need for further intervention via surgery or interventional radiology), and adverse events. RESULTS The median size of the WON was 9.5 cm (range, 4-30 cm). Eight patients had 2 LAMS placed for multiport access, all with technical success (100%). Clinical success was achieved in 107 patients (86.3%) after 3 months of follow-up. Thirteen patients required a percutaneous drain, and 3 required a surgical intervention to manage their WON. The stents remained patent in 94% of patients (117 of 124) and migrated in 5.6% of patients (7 of 124). The median number of endoscopic interventions was 2 (range, 1-9 interventions). CONCLUSIONS On the basis of a retrospective analysis of 124 patients, endoscopic therapy of WON by using LAMS is safe and effective. Creation of a large and sustained cystogastrostomy or cystoenterostomy tract is effective in the drainage and treatment of WON.

Abstract
BACKGROUND AND AIMS Current modalities for lymph node staging in cancer can be limited. We sought to evaluate the feasibility of needle-based confocal laser endomicroscopy (nCLE) at the time of endoscopic ultrasound (EUS) and to describe the nCLE features that distinguish between benign, malignant, and inflammatory lymph nodes. METHODS We collected data on 28 consecutive patients during EUS staging of malignancy or assessment of enlarged lymph nodes. Patients underwent nCLE at the time of EUS followed by fine needle biopsy. nCLE images were correlated with the patients' final histopathology. RESULTS All 28 patients successfully underwent nCLE during EUS without adverse events. There were 17 cases of carcinoma, 4 lymphoid malignancies, and 7 benign lymph nodes. We characterized the various nCLE features of the lymph node capsule and cortex. Features of carcinoma, such as clusters of dark pleomorphic tumor cells, were identified and found to correlate well with the final pathology. Lymphoid malignancies often had enlarged follicles, but this was inconsistent. CONCLUSIONS nCLE of lymph nodes at the time of EUS is feasible and appears to be safe. Dark pleomorphic cells were readily identified in all of the malignant lymph nodes and correlated with tumor cells seen on histology.

Abstract
BACKGROUND AND AIMS The need for transpapillary drainage (TPD) in patients undergoing transmural drainage (TMD) of pancreatic fluid collections (PFCs) remains unclear. The aims of this study were to compare treatment outcomes between patients with pancreatic pseudocysts undergoing TMD versus combined (TMD and TPD) drainage (CD) and to identify predictors of symptomatic and radiologic resolution. METHODS This is a retrospective review of 375 consecutive patients with PFCs who underwent EUS-guided TMD from 2008 to 2014 at 15 academic centers in the United States. Main outcome measures included TMD and CD technical success, treatment outcomes (symptomatic and radiologic resolution) at follow-up, and predictors of treatment outcomes on logistic regression. RESULTS A total of 375 patients underwent EUS-guided TMD of PFCs, of which 174 were pseudocysts. TMD alone was performed in 95 (55%) and CD in 79 (45%) pseudocysts. Technical success was as follows: TMD, 92 (97%) versus CD, 35 (44%) (P = .0001). There was no difference in adverse events between the TMD (15%) and CD (14%) cohorts (P = .23). Median long-term (LT) follow-up after transmural stent removal was 324 days (interquartile range, 72-493 days) for TMD and 201 days (interquartile range, 150-493 days) (P = .37). There was no difference in LT symptomatic resolution (TMD, 69% vs CD, 62%; P = .61) or LT radiologic resolution (TMD, 71% vs CD, 67%; P = .79). TPD attempt was negatively associated with LT radiologic resolution of pseudocyst (odds ratio, 0.11; 95% confidence interval, 0.02-0.8; P = .03). CONCLUSIONS TPD has no benefit on treatment outcomes in patients undergoing EUS-guided TMD of pancreatic pseudocysts and negatively affects LT resolution of PFCs.

Abstract
BACKGROUND Probe-based confocal laser endomicroscopy (pCLE) provides microscopic imaging during an endoscopic procedure. Its introduction as a standard modality in gastroenterology has brought significant progress in management strategies, affecting many aspects of clinical care and requiring standardisation of practice and training. OBJECTIVE This study aimed to provide guidance on the standardisation of its practice and training in Barrett's oesophagus, biliary strictures, colorectal lesions and inflammatory bowel diseases. METHODS Initial statements were developed by five group leaders, based on the available clinical evidence. These statements were then voted and edited by the 26 participants, using a modified Delphi approach. After two rounds of votes, statements were validated if the threshold of agreement was higher than 75%. RESULTS Twenty-six experts participated and, among a total of 77 statements, 61 were adopted (79%) and 16 were rejected (21%). The adoption of each statement was justified by the grade of evidence. CONCLUSION pCLE should be used to enhance the diagnostic arsenal in the evaluation of these indications, by providing microscopic information which improves the diagnostic performance of the physician. In order actually to implement this technology in the clinical routine, and to ensure good practice, standardised initial and continuing institutional training programmes should be established.

Abstract
BACKGROUND The most common complication of uncovered biliary self-expandable metal stents (SEMSs) is tumor ingrowth. The addition of an impenetrable covering may prolong stent patency. OBJECTIVE To compare stent patency between uncovered and partially covered SEMSs in malignant biliary obstruction. DESIGN Multicenter randomized trial. SETTING Four teaching hospitals. PATIENTS Adults with inoperable distal malignant biliary obstruction. INTERVENTIONS Uncovered or partially covered SEMS insertion. MAIN OUTCOME MEASURES Time to recurrent biliary obstruction, patient survival, serious adverse events, and mechanism of recurrent biliary obstruction. RESULTS From October 2002 to May 2008, 129 patients were randomized. Recurrent biliary obstruction was observed in 11 of 61 uncovered SEMSs (18%) and 20 of 68 partially covered SEMSs (29%). The median times to recurrent biliary obstruction were 711 days and 357 days for the uncovered and partially covered SEMS groups, respectively (P = .530). Median patient survival was 239 days for the uncovered SEMS and 227 days for the partially covered SEMS groups (P = .997). Serious adverse events occurred in 27 (44%) and 42 (62%) patients in the uncovered and partially covered SEMS groups, respectively (P = .046). None of the uncovered and 8 (12%) of the partially covered SEMSs migrated (P = .0061). LIMITATIONS Intended sample size was not reached. Allocation to treatment groups was unequal. CONCLUSIONS There was no significant difference in time to recurrent biliary obstruction or patient survival between the partially covered and uncovered SEMS groups. Partially covered SEMSs were associated with more serious adverse events, particularly migration.

Abstract
BACKGROUND Acute pancreatitis is a most serious complication following endoscopic retrograde cholangiopancreatography (ERCP). Previous meta-analyses and randomized controlled trials have shown conflicting results regarding the preventive efficacy of somatostatin or octreotide for this complication. The aim of this study was to resolve these conflicts. METHODS A standardized comprehensive literature search was performed through September 2009. Depending on heterogeneity of outcomes, either random-effects model (REM) or fixed-effects model (FEM) was applied to calculate pooled estimates of drug efficacy. RESULTS Seventeen studies, including 3818 participants, met the inclusion criteria. Analysis of somatostatin and octreotide trials showed that these drugs prevented post-ERCP pancreatitis (pooled risk ratio [95% confidence interval; CI], 0.63 [0.42-0.96] in REM. Pooled risk ratios [95% CI] of each subgroup were: 0.52 [0.30-0.90] for somatostatin in REM; 0.30 [0.17-0.53] for high-dose somatostatin infused over 12 h in FEM; 0.27 [0.13-0.52] for bolus somatostatin in FEM; 0.35 [0.15-0.82] for pancreatic duct (PD) injection with somatostatin in FEM; 0.33 [0.16-0.70] for biliary sphincterotomy (BS) with somatostatin in FEM; 0.53 [0.24-1.17] for intention-to-treat (ITT) analysis with somatostatin in REM; 0.42 [0.20-0.90] for high-dose octreotide in FEM; 0.61 [0.27-1.35] for PD injection with octreotide in FEM; 0.64 [0.32-1.29] for BS with octreotide in FEM; and 0.83 [0.34-2.03] for ITT analysis with octreotide in REM. CONCLUSIONS Somatostatin and high-dose octreotide may prevent post-ERCP pancreatitis. The preventive efficacy of somatostatin is more prominent in cases of PD injection, or BS, or high-dose administration over 12 h, or bolus injection.

A novel device for endoscopic submucosal dissection that combines water-jet submucosal hydrodissection and elevation with electrocautery: initial experience in a porcine model. Gastrointest Endosc 2010; 71:615-8.

Abstract
BACKGROUND Endoscopic submucosal dissection requires a high degree of endoscopic skill and specifically designed dissecting instruments. OBJECTIVE To describe the technique for endoscopic submucosal dissection when using the ERBE Hybrid Knife, which combines an ultrafine high-pressure water jet with an electrocautery needle. DESIGN Descriptive study (ex vivo and in vivo porcine esophagus, stomach, and colon). INTERVENTIONS The only instrument used for the dissection was the ERBE Hybrid Knife. The high-pressure water jet was used at a pressure between 45 and 60 bar for creating submucosal fluid elevation. After this, circumferential mucosal incisions and submucosal dissection were performed with the FORCED COAG and ENDOCUT D modes of the same device. The water jet was used intermittently during the dissection process. MAIN OUTCOME MEASUREMENTS At the end of the in vivo experiments, animals were killed and the organs removed for evaluation. RESULTS Multiple endoscopic submucosal dissection procedures were successfully performed. It was possible to create submucosal fluid cushions rapidly. Repeated fluid injections during dissection were easily facilitated with the same device. All ex vivo gastric endoscopic submucosal dissections of 50 x 40-mm lesions were completed within 10 minutes. In the in vivo studies, the mean size of the gastric and colonic specimens was 3.7 +/- 2.1 x 2.3 +/- 1 cm, and the dissections were completed within 8 minutes. No thermal injury was observed on the serosa, and no perforations were detected. CONCLUSIONS Endoscopic submucosal dissection can be safely and effectively achieved in a porcine model with the ERBE Hybrid Knife and should be considered a suitable device for this procedure in humans.

Abstract
OBJECTIVES We sought to test the hypothesis that placement of a new nitinol duodenal self-expandable metallic stent (SEMS) for palliation of malignant gastroduodenal obstruction is effective and safe in allowing patients to tolerate an oral diet. METHODS In a prospective multicenter study, SEMSs (Duodenal WallFlex, Boston Scientific) were placed to alleviate gastroduodenal obstruction in inoperable patients without the ability to tolerate solid food. The primary study end point was improvement in oral intake monitored according to the 4-point Gastric Outlet Obstruction Scoring System (GOOSS) up to 24 weeks after stent placement. RESULTS Forty-three patients received SEMSs, which were successfully deployed on the first attempt in 41 cases (95%) and the second attempt in two (5%). Within 1 day and 7 days after SEMS placement, 52% and 75% of patients, respectively, benefited from a GOOSS increase > or =1. Resumption of solid food intake (GOOSS 2-3) was attained by 56% of patients within 7 days and 80% by 28 days. Of the patients attaining GOOSS 2-3, 48% remained on solid food until death or last follow-up. Device-related adverse events included stent occlusion/malfunction in 9% of patients and perforation in 5% of patients. CONCLUSIONS Duodenal WallFlex stent placement promptly improves oral intake in a majority of inoperable patients with malignant gastroduodenal obstruction. In approximately half the patients achieving GOOSS 2-3, the capacity for solid food intake endures until death or last follow-up.

Abstract
BACKGROUND Patients with Roux-en-Y gastric bypass (RYGB) present a unique problem if they require diagnostic or therapeutic interventions for which the pancreatobiliary limb or the defunctionalized stomach must be accessed. Novel shape-locking guides have been reported in the literature to reduce looping during colonoscopy, and a new guide is now available to assist with enteroscopy. OBJECTIVE To use ShapeLock technology to permit evaluation of the defunctionalized stomach. DESIGN Observational case series. SETTING Tertiary-care center. PATIENTS Nine patients with a history of RYGB referred for repeat endoscopic evaluation after initial enteroscopy failed to reach the excluded stomach. INTERVENTIONS After achieving appropriate levels of sedation, a standard enteroscope was back-loaded with the ShapeLock enteroscopy guide and was inserted through the mouth. The device was moved through the gastrojejunal (GJ) anastomosis, along the Roux limb, and into the distal pancreatobiliary limb. The device was then locked, which allowed the enteroscope to be advanced to the defunctionalized stomach. RESULTS The ShapeLock guide was able to be advanced to the excluded stomach and perform a thorough examination of the pancreatobiliary limb in 8 of 9 patients, without complications. In 1 patient, the diameter of the GJ anastomosis prevented passage of the device. CONCLUSIONS The ShapeLock enteroscopy guide can allow access to the upper-GI tract in patients after RYGB, provided the GJ anastomosis is of adequate diameter. This study suggested that the technique is safe and has the potential to allow therapeutic interventions in the defunctionalized stomach and duodenum, including ERCP.

Abstract
BACKGROUND Endoluminal gastroplication has been shown to reduce symptoms of gastroesophageal reflux disease and to induce focal hypertrophy of the gastroesophageal junction (GEJ) muscularis propria. Despite suture loss, some patients have persistent symptomatic resolution. OBJECTIVE This study was designed to examine the durability of smooth muscle hypertrophy after suture removal. DESIGN Seven pigs underwent upper endoscopy with endoscopic ultrasonography (EGD/EUS) at baseline to evaluate GEJ muscularis propria layer. Endoluminal gastroplication was performed at week 1 with placement of 2 sutures at the GEJ. Repeat EGD/EUS was performed at week 3 and week 5. Three of the 7 pigs were killed for histologic analysis. The remaining 4 pigs had sutures removed and survived for 9, 11, and 13 weeks; serial weekly EGD/EUS was performed until the animal was killed. RESULTS The GEJ muscularis propria thickness by EUS was 1.1+/-0.1 mm at baseline, 4.7+/-1.9 mm at week 3, and 4.4+/-1.1 mm at week 5. The muscularis propria thickness by histologic examination in the 3 animals with sutures intact were 6.2+/-0.3 mm near the suture site and 4.7+/-0.5 mm at the opposing wall to the suture site. For the 4 animals with sutures removed, the measurements were 6.9+/-0.2 mm (suture site) and 4.7+/-0.5 mm (opposing wall), respectively. CONCLUSIONS The GEJ smooth muscle cell hypertrophy induced by endoluminal gastroplication persisted after removal of mucosal sutures. These changes may be responsible for persistent symptomatic response despite suture loss in patients.
