RESUMO
BACKGROUND: Viral infections are known to impact the pancreato-biliary system; however, there are limited data showing that the same is true of COVID-19. Endoscopic retrograde cholangiopancreatography (ERCP) can safely be performed in patients with COVID-19 infection, but outcomes of patients with COVID-19 infections and concomitant pancreatic and biliary disease requiring endoscopic intervention are unknown. AIMS: This study aims to evaluate the severity of pancreaticobiliary diseases and post-ERCP outcomes in COVID-19 patients. METHODS: Patients with pancreato-biliary disease that required inpatient ERCP from five centers in the United States and South America between January 1, 2020, and October 31, 2020 were included. A representative cohort of patients from each month were randomly selected from each site. Disease severity and post-ERCP outcomes were compared between COVID-19 positive and COVID-19 negative patients. RESULTS: A total of 175 patients were included: 95 COVID positive and 80 COVID negative. Mean CTSI score for the patients who had pancreatitis was higher in COVID-positive cohort by 3.2 points (p < .00001). The COVID-positive group had more cases with severe disease (n = 41) versus the COVID-negative group (n = 2) (p < .00001). Mortality was higher in the COVID-19 positive group (19%) compared to COVID-negative group (7.5%) even though the COVID-19-negative group had higher incidence of malignancy (n = 17, 21% vs n = 7, 7.3%) (p = 0.0455). CONCLUSIONS: This study shows that patients with COVID infection have more severe pancreato-biliary disease and worse post-ERCP outcomes, including longer length of stay and higher mortality rate. These are important considerations when planning for endoscopic intervention. CLINICALTRIALS: gov: (NCT05051358).
RESUMO
Endoscopic retrograde cholangiopancreatography (ERCP) is the standard of care in the management of unresectable malignant biliary obstruction. However, endoscopic ultrasound (EUS)-guided biliary drainage has become widely accepted over the past several years for complicated biliary drainage in cases when ERCP is unsuccessful or not feasible. Recent emerging evidence suggests EUS-guided hepaticogastrostomy and EUS-guided choledochoduodenostomy are noninferior, and possibly even superior to conventional ERCP for primary palliation of malignant biliary obstruction. This article reviews the procedural techniques and considerations of the different techniques as well as comparative literature on safety and efficacy between techniques.

INTRODUCTION: Endoscopic ultrasound-guided biliary drainage (EUS-BD) is the procedure of choice for patients who cannot undergo endoscopic retrograde cholangiopancreatography (ERCP). The outcomes of patients undergoing surgery after EUS-BD for malignancy are unknown. METHODS: We conducted an international, multicenter retrospective comparative study of patients who underwent hepatobiliary surgery after having undergone EUS-BD or ERCP from 6 tertiary care centers. Patient demographics, procedural data, and follow-up care were collected in a registry. RESULTS: One hundred forty-five patients were included: EUS-BD n=58 (mean age 66, 45% male), ERCP n=87 (mean age 68, 53% male). The majority of patients had pancreatic cancer, cholangiocarcinoma, or gallbladder malignancy. In the EUS-BD group, 29 patients had hepaticogastrostomy, 24 had choledochoduodenostomy, and 5 had rendezvous technique done. The most common surgery was Whipple in both groups (n=41 EUS-BD, n=56 ERCP) followed by partial hepatectomy (n=7 EUS-BD, n=14 ERCP) and cholecystectomy (n=2 EUS-BD, n=2 ERCP). Endoscopy clinical success was comparable in both groups (98% EUS-BD, 94% ERCP). Adverse event rates were similar in both groups: EUS-BD (n=10, 17%) and ERCP (n=23, 26%). Surgery technical success and clinical success were significantly higher in the EUS-BD group compared with the ERCP group (97% vs. 83%, 97% vs. 75%). Total Hospital stay from surgery to discharge was significantly higher in the ERCP group (19 d vs. 10 d, P =0.0082). DISCUSSION: Undergoing EUS-BD versus ERCP before hepatobiliary surgery is associated with fewer repeat endoscopic interventions, shorter duration between endoscopy and surgical intervention, higher rates of surgical clinical success, and shorter length of hospital stay after surgery.

BACKGROUND: Endoscopic submucosal dissection (ESD) and transanal endoscopic microsurgery (TEM) are minimally invasive procedures that treat early rectal cancer (ERC). Both are effective treatments, yet there are very few studies comparing them. The aim of our study was to identify ideal candidates for each procedure. MATERIALS AND METHODS: Between January 2016 and November 2019, 204 ERC patients were managed with either ESD (n=101) or TEM (n=103) at 7 international centers. Data analyzed included clinical success, tumor characteristics, procedure info, and recurrence rates. RESULTS: Median tumor size was 40 mm±23.9 in the ESD group and 56 mm±27.9 in the TEM group, significantly larger in the latter ( P <0.00001). Average procedure time was 131.5±67.9 minutes in ESD group and 104.9±28.4 minutes in TEM group ( P =0.000347). Average hospital stay was 3.3±2.6 days in the ESD group and 4.7±0.7 days in the TEM group ( P <0.00001). Adverse event rate was 6.8% in the ESD group and 24% in the TEM group. There were no significant difference in the rate of en bloc resection, technical success, tumor location, necessity of additional procedures, and tumor recurrence rates. CONCLUSION: Compared with TEM, ESD is a safer procedure with shorter hospital stay and should be offered for patients who have ERC.

INTRODUCTION: Single-use disposable duodenoscopes (SDD) have been developed to mitigate infectious risks related to reusable duodenoscopes. The aim of this study is to compare the safety and efficacy of the two available SDDs in the United States. METHODS: We conducted a comparative study of 2 SDD in consecutive ERCP procedures performed by expert endoscopists from 9 academic centers. Performance ratings, procedure details, and adverse events were collected. RESULTS: A total of 201 patients were included: 129 patients underwent ERCP with Exalt (mean age 63, Males- 66 (51%), 72 with aScope Duodeno (mean age 65, males=30 (42%). A majority of endoscopists had performed >2000 ERCPs in both groups (71% Exalt, 93% aScope Duodeno). Technical success was 92% in both groups (n=119 Exalt-group, n=66 aScope-Duodeno-group). The procedural complexity for the ERCP cases performed were: Grade 1: 35 cases (18%), Grade 2: 83 cases (41%), Grade 3: 65 cases (32%), and Grade 4: 18 cases (9%). Thirteen patients (10%) from the Exalt group and 16 patients (22%) from the aScope Duodeno group required conversion to a reusable duodenoscope. On a scale of 1 to 5, Exalt and aScope Duodeno, respectively, were rated: 2.31 versus 2.60 for location and visualization quality, 1.38 versus 1.57 for maneuverability based on papillary orientation, 1.48 versus 1.15 for suction/air control, and 2.31 versus 2.34 for elevator efficiency. None of the adverse events were related to the SDDs. CONCLUSIONS: The 2 SDDs were comparable. Further ongoing enhancements to these devices will improve maneuverability and clinical effectiveness.

BACKGROUND: Endoscopic ultrasound (EUS)-guided gastroenterostomy (EUS-GE) is a minimally invasive therapy for patients with gastric outlet obstruction without the risks of surgical bypass and the limited long-term efficacy of enteral self-expanding metal stent placement. However, due to its novelty, there is a lack of significant data comparing long-term outcomes of patients with EUS-GE, based on the underlying disease. In this study, we compare outcomes of EUS-GE on benign versus malignant indications. METHODS: Consecutive patients from 12 international, tertiary care centers who underwent EUS-GE over 3 years were extracted in a retrospective registry. Demographic characteristics, procedure-related information and follow-up data was collected. Primary outcome was the rate of adverse events associated with EUS-GE and the comparison of the rate of adverse events in benign versus malignant diseases. Secondary outcomes included technical and clinical success as well as hospitalization admission. RESULTS: A total of 103 patients were included: 72 malignant and 31 benign. The characteristics of the patients undergoing EUS-GE is shown in Table 1. The mean age of the cohort was 68 years and 58 years for malignant and benign etiology. Gender distribution was 57% and 39% being females in malignant and benign etiology group, respectively. Clinical success, technical success, average procedure time, and hospital length of stay were similar in both groups. Patients with benign underlying etiology had significantly higher number of surgically altered midgut anatomy (P=0.0379). CONCLUSION: EUS-GE is equally efficient regardless of the underlying etiology (malignant vs. benign), and the adverse events both groups were comparable.
RESUMO
BACKGROUND: Endoscopic ultrasound-directed transgastric ERCP (EDGE) has become standard-of-care therapy at many centers for pancreaticobiliary disease in patients with Roux-en-Y Gastric Bypass. In this study, we aimed to evaluate the opinions and practices of endoscopists who perform EDGE. METHODS: A 22-question utilization of EDGE survey was sent to 36 advanced endoscopists at tertiary care centers in the United States. The two-section survey included questions regarding advanced endoscopy volume and training at the respective facilities, and questions on specific details of EDGE utilization. RESULTS: Among 36 interventional endoscopists (IE) surveyed, 14 (39%) reported performing > 1000 ERCPs annually. Thirty (83%) offered EDGE as an option for Roux-en-Y gastric bypass patients with previous cholecystectomy. Other options offered included: 19 (53%) offered Laparoscopy-assisted ERCP (LA-ERCP), 7 (19%) offered Single-Balloon ERCP (SBE), and 10 (28%) offered percutaneous drainage (PTC). Twenty (56%) IE performed 10 or less EDGE procedures, while 16 (44%) performed 11 or more. Single-session EDGE was performed by 7 (19%) IE, while 15 (42%) performed dual session, and 13 (36%) performed both. 19 (53%) actively closed fistulas while 17 (47%) let them close spontaneously. Thirty one (86%) reported a technical success rate of 91% to 100%. The most frequently reported immediate adverse event post-procedurally was abdominal pain, reported by 17 IE (47%). Weight gain was reported by 2 IE (6%). CONCLUSION: EDGE continues to gain in popularity as an option for Roux-en-Y gastric bypass patients requiring pancreaticobiliary interventions, with 24/36 IE (67%) believing that it should be the new standard. In addition, most report a low frequency of post-procedural weight gain. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT05041608.

BACKGROUND AND AIMS: Digital single-operator cholangioscopy (DSOC) allows direct visualization of the biliary tree for evaluation of biliary strictures. Our objective was to assess the interobserver agreement (IOA) of DSOC interpretation for indeterminate biliary strictures using newly refined criteria. METHODS: Fourteen endoscopists were asked to review an atlas of reference clips and images of 5 criteria derived from expert consensus. They then proceeded to score 50 deidentified DSOC video clips based on the visualization of tortuous and dilated vessels, irregular nodulations, raised intraductal lesions, irregular surface with or without ulcerations, and friability. The endoscopists then diagnosed the clips as neoplastic or non-neoplastic. Intraclass correlation (ICC) analysis was done to evaluate inter-rater agreement for both criteria sets and final diagnosis. RESULTS: Clips of 41 malignant lesions and 9 benign lesions were scored. Three of 5 revised criteria had almost perfect agreement. ICC was almost perfect for presence of tortuous and dilated vessels (.86), raised intraductal lesions (.90), and presence of friability (.83); substantial agreement for presence of irregular nodulations (.71); and moderate agreement for presence of irregular surface with or without ulcerations (.44). The diagnostic ICC was almost perfect for neoplastic (.90) and non-neoplastic (.90) diagnoses. The overall diagnostic accuracy using the revised criteria was 77%, ranging from 64% to 88%. CONCLUSIONS: The IOA and accuracy rate of DSOC using the new Mendoza criteria shows a significant increase of 16% and 20% compared with previous criteria. The reference atlas helps with formal training and may improve diagnostic accuracy. (Clinical trial registration number: NCT02166099.).

BACKGROUND AND AIMS: Direct endoscopic necrosectomy (DEN) of walled-off pancreatic necrosis (WOPN) lacks dedicated instruments and requires repetitive and cumbersome procedures. This study evaluated the safety and efficacy of a new powered endoscopic debridement (PED) system designed to simultaneously resect and remove solid debris within WOPN. METHODS: This was a single-arm, prospective, multicenter, international device trial conducted from November 2018 to August 2019 at 10 sites. Patients with WOPN ≥6 cm and ≤22 cm and with >30% solid debris were enrolled. The primary endpoint was safety through 21 days after the last DEN procedure. Efficacy outcomes included clearance of necrosis, procedural time, adequacy of debridement, number of procedures until resolution, hospital stay duration, and quality of life. RESULTS: Thirty patients (mean age, 55 years; 60% men) underwent DEN with no device-related adverse events. Of 30 patients, 15 (50%) achieved complete debridement in 1 session and 20 (67%) achieved complete debridement within 2 or fewer sessions. A median of 1.5 interventions (range, 1-7) were required. Median hospital stay was 10 days (interquartile range, 22). There was an overall reduction of 91% in percent necrosis within WOPN from baseline to follow-up and 85% in collection volume. Baseline WOPN volume was positively correlated with the total number of interventions (ρ = .363, P = .049). CONCLUSIONS: The new PED system seems to be a safe and effective treatment tool for WOPN, resulting in fewer interventions and lower hospital duration when compared with published data on using conventional instruments. Randomized controlled trials comparing the PED system with conventional DEN are needed. (Clinical trial registration number: NCT03694210.).

INTRODUCTION: Gastric peroral endoscopic pyloromyotomy (G-POEM) is a novel option for patients with gastroparesis. It involves submucosal tunneling across the pylorus, followed by pyloromyotomy, and subsequent closure of the endoscopic tunnel. The aim of this study was to determine the learning curve for G-POEM. METHODS: Consecutive patients undergoing G-POEM by a single operator were included from a prospective registry over 2 years. Demographics, procedure info, postprocedure follow-up data, and adverse events were collected. Nonlinear regression and cumulative sum control chart analyses were conducted for the learning curve. Clinical outcomes were improvement in Gastroparesis Cardinal Symptom Index score and gastric emptying scintigraphy. RESULTS: Thirty-six patients were included (16.7% M, mean age 46 y). The majority had idiopathic gastroparesis (n=16, 44%), with the remaining having diabetes (n=5, 17%), postsurgical (n=10, 28%), or other (n=4, 11%). Technical success was achieved in 35 of 36 (97%). There was a significant reduction in the total Gastroparesis Cardinal Symptom Index score (2.09 units, P<0.00001) and a significant reduction in postoperative gastric emptying scintigraphy (82.44 mins, P<0.00001). Mean follow-up was 15 months (SD, 1.05). Median procedure time was 60.5 minutes (range, 35 to 136). Cumulative sum control chart shows 60-minute procedure was achieved at the 18th procedure. Procedure durations further reduced with consequent procedures with the last 3 being 45 minutes, thus demonstrating continued improvement with ongoing experience (nonlinear regression P<0.0001). CONCLUSION: Endoscopists experienced in G-POEM are expected to achieve a reduction in procedure time over successive cases, with efficiency reached at 60.5 minutes and a learning rate of 18 cases with continuing improvement.

BACKGROUND: Visual characteristics seen during digital single-operator cholangioscopy (DSOC) have not been validated. The aim of this 2-phase study was to define terminology by consensus for the visual diagnosis of biliary lesions to develop a model for optimization of the diagnostic performance of DSOC. MATERIALS AND METHODS: In phase 1 (criteria identification), video-cholangioscopy clips were reviewed by 12 expert biliary endoscopists, who were blinded to the final diagnosis. Visual criteria were consolidated into the following categories: (1) stricture, (2) lesion, (3) mucosal features, (4) papillary projections, (5) ulceration, (6) abnormal vessels, (7) scarring, (8) pronounced pit pattern.During the second phase (validation), 14 expert endoscopists reviewed DSOC (SpyGlass DS, Boston Scientific) clips using the 8 criteria to assess interobserver agreement (IOA) rate. RESULTS: In phase 1, consensus for visual findings were categorized into 8 criteria titled the "Monaco Classification." The frequency of criteria were: (1) presence of stricture-75%, (2) presence of lesion type-55%, (3) mucosal features-55%, (4) papillary projections-45%, (5) ulceration-42.5%, (6) abnormal vessels-10%, (7) scarring-40%, and (8) pronounced pit pattern-10%. The accuracy on final diagnosis based on visual impression alone was 70%.In phase 2, the IOA rate using Monaco Classification criteria ranged from slight to fair. The presumptive diagnosis IOA was fair (κ=0.31, SE=0.02), and overall diagnostic accuracy was 70%. CONCLUSIONS: The Monaco classification identifies 8 visual criteria for biliary lesions on single-operator digital cholangioscopy. Using the criteria, the IOA and diagnostic accuracy rate of DSOC is improved compared with prior studies.

INTRODUCTION: Endoscopic management of Zenker diverticuli (ZD) has traditionally been via septotomy technique. The recent development of tunneling technique has shown to be both efficacious and safe. The aim of this study is to evaluate the tunneling technique using per oral endoscopic myotomy (Z-POEM) versus septotomy. METHODS: Patients who underwent endoscopic management of ZD either by Z-POEM or septotomy from March 2017 until November 2020 from 9 international academic centers were included. Demographics, clinical data preprocedure and postprocedure, procedure time, adverse events, and hospital length of stay were analyzed. RESULTS: A total of 101 patients (mean age 74.9 y old, 55.4% male) were included: septotomy (n=49), Z-POEM (n=52). Preprocedure Functional Oral Intake Scale score and Eckardt score was 5.3 and 5.4 for the septotomy group and 5.9 and 5.15 for the Z-POEM group. Technical success was achieved in 98% of the Z-POEM group and 100% of the septotomy group. Clinical success was achieved in 84% and 92% in the septotomy versus Z-POEM groups. Adverse events occurred in 30.6% (n=15) in septotomy group versus 9.6% (n=5) in the Z-POEM group (P=0.017). Reintervention for ongoing symptoms occurred in 7 patients in the septotomy group and 3 patients in the Z-POEM group. Mean hospital length of stay was shorter for the Z-POEM group, at 1.5 versus 1.9 days. CONCLUSIONS: A tunneling technique via the Z-POEM procedure is an efficacious and safe endoscopic treatment for ZD. Z-POEM is a safer procedure with a statistically significant reduction in adverse events compared with traditional septotomy technique.

BACKGROUND: Digital single-operator cholangioscopy (DSOC) (SpyGlass DS™, Boston Scientific, MA, USA) allows for high-definition imaging of the biliary tree. The superior visualization has led to the development of two different sets of criteria to evaluate and classify indeterminate biliary strictures: the Monaco criteria and the criteria in Carlos Robles-Medranda's publication (CRM). Our objective was to assess the interrater agreement (IA) of DSOC interpretation for indeterminate biliary strictures using the two newly published criteria. METHODS: Forty de-identified DSOC video recordings were sent to 15 interventional endoscopists with experience in cholangioscopy. They were asked to score the videos based on the presence of Monaco Classification criteria: stricture, lesion, mucosal changes, papillary projections, ulceration, white linear bands or rings, and vessels. Next, they scored the videos using CRM criteria: villous pattern, polypoid pattern, inflammatory pattern, flat pattern, ulcerate pattern and honeycomb pattern. The endoscopists then diagnosed the recordings as neoplastic or non-neoplastic based on the criteria. Intraclass correlation (ICC) analysis was done to evaluate interrater agreement for both criteria set and final diagnosis. RESULTS: Recordings of 26 malignant lesions and 14 benign lesions were scored. The IA using both the Monaco criteria and CRM criteria ranged from poor to excellent (range 0.1-0.76) and (range 0.1-0.62), respectively. Within the Monaco criteria, IA was excellent for lesion (0.75) and fingerlike papillary projections (0.74); good for tortuous vessels (0.7), mucosal features (0.62), uniform papillary projections (0.53), and ulceration (0.58); and fair for white linear bands (0.4). Within the CRM criteria, the IA was good for villous pattern (0.62), flat pattern (0.62), and honeycomb pattern; fair for ulcerated pattern (0.56), polypoid pattern (0.52) and inflammatory pattern (0.54). The diagnostic IA using Monaco criteria was good (0.65), while the diagnostic IA using CRM was fair (0.58). The overall diagnostic accuracy using the Monaco classification was 61% and CRM criteria were 57%. CONCLUSION: The IOA and accuracy rate of DSOC using visual criteria from both Monaco Criteria and CRM are similar. However, some criteria from both sets suffer from poor IA, thus affecting the overall diagnostic accuracy. More formal training and refinements in visual criteria with additional validation are needed to improve diagnostic accuracy. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02166099.

BACKGROUND AND AIMS: EUS-directed transgastric ERCP (the EDGE procedure) is a simplified method of performing ERCP in Roux-en-Y gastric bypass patients. The EDGE procedure involves placement of a lumen-apposing metal stent (LAMS) into the excluded stomach to serve as a conduit for passage of the duodenoscope for pancreatobiliary intervention. Originally a multistep process, urgent indications for ERCP have led to the development of single-session EDGE (SS-EDGE) with LAMS placement and ERCP performed in the same session. The goal of this study was to identify predictive factors of intraprocedural LAMS migration in SS-EDGE. METHODS: We conducted a multicenter retrospective review that included 9 tertiary medical centers across the United States. Data were collected and analyzed from 128 SS-EDGE procedures. The primary outcome was intraprocedural LAMS migration. Secondary outcomes were other procedural adverse events such as bleeding and perforation. RESULTS: Eleven LAMS migrations were observed in 128 procedures (8.6%). Univariate analysis of clinically relevant variables was performed, as was a binary logistic regression analysis of stent diameter and stent dilation. This revealed that use of a smaller (15 mm) diameter LAMS was an independent predictor of intraprocedural stent migration (odds ratio, 5.36; 95% confidence interval, 1.29-22.24; P = .021). Adverse events included 3 patients who required surgery and 2 who experienced intraprocedural bleeding. CONCLUSIONS: Use of a larger-diameter LAMS is a predictive factor for a nonmigrated stent and improved procedural success in SS-EDGE. Although larger patient cohorts are needed to adequately assess these findings, performance of LAMS dilation and fixation may also decrease risk of intraprocedural LAMS migration and improve procedural success.

INTRODUCTION: Endoscopic ultrasound guided gastroenterostomy (EUS-GE) is a minimally invasive option for gastric outlet obstruction. It requires skills in endoscopic ultrasound, fluoroscopy, and lumen-apposing metal stent deployment. The aim of this study was to determine the learning curve for EUS-GE. METHODS: Consecutive patients undergoing EUS-GE by a single operator were included from a prospective registry over 3 years. Demographics, procedure info, postprocedure follow-up data, and adverse events were collected. Nonlinear regression and cumulative sum analyses were conducted for the learning curve. Clinical success was defined as tolerating a diet postprocedure. RESULTS: Twenty-three patients were included (39% male, mean age 65.8 y). Technical success was achieved in 22 (96%) patients. Clinical success was achieved in 21/22 (95%) patients. Average follow-up time 10.8 months (9.1 SD). Five patients had minor postprocedure complications; 1 patient had a periprocedural esophageal tear treated with clips. Four patients required repeat intervention for stent revision or removal if no longer needed.Median procedure time was 88 minutes (range: 45 to 140 min). Cumulative sum chart shows 88-minute procedure time was achieved at the seventh procedure indicating efficiency. Even with bridging of a misdeployed lumen-apposing metal stent, the procedure duration further reduced with consequent procedures indicating continued improvement with experience (nonlinear regression P<0.0001). CONCLUSIONS: Endoscopists experienced in EUS-GE achieve a reduction in procedure time over successive cases, with efficiency reached at 88 minutes and a learning rate of 7 cases. Misdeployed stents that require bridging add to the procedure time even after competency is achieved but do not affect the overall learning curve trend.

BACKGROUND AND AIM: Gastroparesis is a potentially debilitating gastric motility disorder with limited treatment options. Highest efficacy treatments include gastric per-oral endoscopic myotomy (GPOEM) and surgical pyloromyotomy. This study compares the efficacy and safety of GPOEM versus laparoscopic pyloromyotomy for refractory gastroparesis. METHODS: Patients who underwent GPOEM or laparoscopic pyloromyotomy for refractory gastroparesis from four centers across the USA and Latin America were included in a dedicated registry. Data collected included patient demographics, imaging, laboratory values, clinical success, gastroparesis cardinal symptom index, procedure time, pre-op and post-op gastric emptying times, adverse events, and hospital length of stay. RESULTS: A total of 102 patients were included (mean age 47; 32.4% male): GPOEM n = 39, surgical pyloromyotomy n = 63.Technical success was 100% in both groups. Clinical success was 92.3% in the GPOEM group and 82.5% in the surgery group (P = 0.164). The GPOEM group had a significantly higher post-op GSCI score reduction by 1.3 units (P < 0.00001), post-op retention reduction at 2 h by 18% (P < 0.00001), post-op retention reduction at 4 h by 25% (P < 0.00001) and a lower procedure time by 20 min (P < 0.00001) as compared with surgery. GPOEM also had a lower hospital length of stay by 2.8 days (P < 0.00001). Adverse events were significantly fewer in the GPOEM group (13%) compared with surgery group (33.3%; P = 0.021). Mean blood loss in the GPOEM group was only 3.6 mL compared with 866 mL in the surgery group. CONCLUSIONS: The GPOEM may be a less invasive, safer, and more efficacious procedural treatment for refractory gastroparesis as compared with surgical pyloromyotomy.

INTRODUCTION: Endoscopic ultrasound (EUS)-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE) is a minimally invasive option for pancreaticobiliary access in patients with Roux-en-Y anatomy. The procedure involves creating a fistulous tract between the remnant stomach or jejunum and the bypassed stomach with the deployment of a lumen-apposing metal stent (LAMS), followed by the advancement of an endoscope through the LAMS to perform an ERCP or EUS. It is a technically challenging procedure, requiring skills in EUS, fluoroscopy, and LAMS deployment. The aim of this study was to determine the learning curve for EDGE. METHODS: Consecutive patients undergoing EDGE by a single operator were included from a prospective registry over 3 years. Demographics, procedure info, postprocedure follow-up data, and adverse events were collected. Nonlinear regression and cumulative sum analyses were conducted for the learning curve. Technical success was defined as the successful creation of the fistulous tract. Clinical success was defined as successful EUS or ERCP via the LAMS. RESULTS: Nineteen patients were included (21% male, mean age 58.7 y). Indication included symptomatic biliary stricture (n=6, 32%), choledocholithiasis (n=5, 26%), pancreatitis (n=3, 16%). Technical success was 100%. All patients had a 15 mm LAMS placed, 3 (16%) had cautery-enhanced LAMS. Clinical success was achieved in 18/19 (95%) patients. Fourteen patients had an ERCP, 1 patient had a EUS, and 3 patients had both. Adverse events included 2 cases of bleeding, 1 case of post-ERCP pancreatitis, and 1 jejunal perforation during duodenoscope insertion managed endoscopically.Median procedure time was 54.5 minutes (range: 31 to 88 min). Cumulative sum chart shows a 54-minute procedure time was achieved at the ninth procedure hence indicating efficiency. Apart from 2 outliers, the procedure duration further reduced with consequent procedures with the last 3 being under 40 minutes indicating that after 25 to 35 procedures a plateau may be reached indicating mastery (nonlinear regression P<0.0001). CONCLUSIONS: Endoscopists experienced in EDGE are expected to achieve a reduction in procedure time over successive cases, with efficiency reached 54.5 minutes and a learning rate of 9 cases. After 25 to 35 procedures, a plateau may be reached indicating mastery.

BACKGROUND AND AIMS: The standard of care for managing pancreaticobiliary disease in altered Roux-en-Y gastric bypass patients is laparoscopy-assisted endoscopic retrograde cholangiopancreatography (LA-ERCP), but is limited by cost and adverse events. Recently a minimally invasive, completely endoscopic approach using endoscopic ultrasound (EUS) directed transgastric ERCP (EDGE) has been described. We aim to compare EDGE to LA-ERCP in this study. METHODS: Patients from May 2005 to June 2017 with Roux-en-Y gastric bypass anatomy having undergone LA-ERCP or EDGE at 4 tertiary centers were captured in a registry. Patient demographics, procedural details, and clinical outcomes were measured for each group. RESULTS: Seventy-two patients (n=29 EDGE, n=43 LA-ERCP) were included in this study. There was no significant difference in the technical success of EDGE gastrogastric fistula (96.5%) versus LA-gastrostomy creation (100%). The success rate of achieving therapeutic ERCP (EDGE 96.5% vs. LA-ERCP 97.7%) and number of ERCP (EDGE 1.2 vs. LA-ERCP 1.02) needed to achieve clinical resolution was similar between both groups. Adverse event rate for EDGE, 24% (7/29) and LA-ERCP, 19% (8/43) was similar. The total procedure time (73 vs. 184 min) and length of hospital stay (0.8 vs. 2.65 d) was significantly shorter for EDGE compared to LA-ERCP. The overall weight change after EDGE was -6.6 lbs at an average 28-week follow-up. CONCLUSIONS: This study suggests that the EDGE procedure has similar technical success and adverse events compared with LA-ERCP with the benefit of significantly shorter procedure times and hospital stay. EDGE may offer a minimally invasive, effective option, with less resource utilization, and without significant weight gain.

BACKGROUND: Endoscopic ultrasound-guided gallbladder drainage (EGBD) with a lumen apposing metal stent is becoming a widely accepted alternative to percutaneous gallbladder drainage (PTGD) for patients who are not candidates for cholecystectomy (CCY). In some patients, medical comorbidites can improve, allowing them to undergo CCY. We compare feasibility and outcomes of interval CCY after EGBD versus PTGD. METHODS: We conducted a multicentered international cohort study of patients who underwent EGBD or PTGD and then underwent interval CCY. Baseline patient demographics, procedural details, and follow-up data were recorded and compared. RESULTS: In total, 34 patients were included. Thirteen patients underwent EGBD followed by CCY (mean age, 53.77±17.27, 46.15% male), and 21 patients underwent PTGD followed by CCY (mean age, 62.14±13.06, 61.9% male). There was no statistically significant difference in mean Charlson Comorbidity Index (P=0.12) or etiology of cholecystitis (P=0.85) between the 2 groups. All patients had a technically successful CCY. There was no difference between rates of open versus laparoscopic CCY (P=1). In addition, there was no difference in postsurgical adverse events (P=0.23). CONCLUSIONS: Surgical CCY after EGBD with lumen apposing metal stent is safe and feasible for the management of cholecystitis. If patient's underlying medical conditions improve, previous EUS-GLB drainage should not preclude patients from undergoing CCY as part of standard of care.

INTRODUCTION: In patients with pancreaticobiliary lesions anticipating surgical resection, digital pancreaticocholangioscopy can be used to identify the extent of disease. This presurgical"mapping" could change the surgical plan and optimize patient care. MATERIALS AND METHODS: Patients with pancreaticobiliary lesions anticipating surgery who underwent endoscopic retrograde cholangiopancreatography with digital pancreaticocholangioscopy from 9 international centers were included. Primary outcome was whether pancreaticocholangioscopy altered the surgical plan. Secondary outcome was correlation between surgical and endoscopic histology and adverse events. RESULTS: A total of 118 patients were included (64% male, mean age 69 y): cholangioscopy in 105 patients (89%), pancreatoscopy in 13 patients (11%). Pancreaticocholangioscopy changed the surgical plan in 39 (34%) of patients: 8 of 13 in the pancreatic duct, 32 of 105 in the bile duct. In the bile duct, 6 patients (5%) had less extensive surgery, 26 patients (25%) avoided surgery. In the pancreatic duct, 4 patients (31%) had more extensive surgery and 4 patients (31%) had less extensive surgery. Four patients with downstaged surgery had positive margins on surgical resection; 1 required additional surgical intervention. Overall correlation between endoscopy and surgical histology was 88%. Adverse events included post endoscopic retrograde cholangiopancreatography pancreatitis in 3 patients (2.5%). CONCLUSION: Digital pancreaticocholangioscopy can be effectively used as a mapping tool to delineate the degree of involvement of biliary lesions before surgical resection, in some cases altering the surgical plan. Prospective studies are needed, especially when downstaging surgery.
