RESUMO
BACKGROUND: Closure of gastrointestinal defects can reduce postprocedural adverse events. Over-the-scope clips and an over-the-scope suturing system are widely available, yet their use may be limited by defect size, location, operator skill level, and need to reinsert the endoscope with the device attached. The introduction of a through-the-scope helix tack suture system (TTSS) allows for closure of large irregular defects using a gastroscope or colonoscope, without the need for endoscope withdrawal. Since its approval 3 years ago, only a handful of studies have explored outcomes using this novel device. METHODS: Multiple databases were searched for studies looking at TTSS closure from inception until August 2023. The primary outcomes were the success of TTSS alone and TTSS with clips for complete defect closure. Secondary outcomes included complete closure based on procedure type (endoscopic mucosal resection [EMR], endoscopic submucosal dissection [ESD]) and adverse events. RESULTS: Eight studies met the inclusion criteria (449 patients, mean defect size 34.3 mm). Complete defect closure rates for TTSS alone and TTSS with adjunctive clips were 77.2% (95%CI 66.4-85.3; I2=79%) and 95.2% (95%CI 90.3-97.7; I2=42.5%), respectively. Complete defect closure rates for EMR and ESD were 99.2% (95%CI 94.3-99.9; I2 = 0%) and 92.1% (95%CI 85-96; I2=0%), respectively. The adverse event rate was 5.4% (95%CI 2.7-10.3; I2=55%). CONCLUSION: TTSS is a novel device for closure of postprocedural defects, with relatively high technical and clinical success rates. Comparative studies of closure devices are needed.

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

DESCRIPTION: Endoscopic gallbladder drainage is a feasible and efficacious alternative to percutaneous drainage in the management of acute cholecystitis for high-risk surgical candidates. Endoscopic ultrasound-guided gallbladder drainage and per-oral cholecystoscopy is facilitated by the use of lumen-apposing metal stents. Endoscopic ultrasound-guided gallbladder drainage should be performed by those expert in advanced therapeutic endoscopic ultrasound. Multidisciplinary collaboration between interventional radiology and surgery is paramount in the care of these patients. Choosing the optimal drainage method is dependent on individual patient characteristics. METHODS: This commentary was drawn from a review of the literature to provide practical advice. Because this was not a systematic review, we did not perform any formal rating of the quality of evidence or strength of the presented considerations. This expert commentary was commissioned and approved by the American Gastroenterological Association (AGA) Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership, and underwent internal peer-review by the Clinical Practice Updates Committee and external peer-review through standard procedures of Clinical Gastroenterology and Hepatology.

BACKGROUND AND AIMS: Interventions for malignant small-bowel obstruction (SBO) may be limited by extent of peritoneal disease, rendering surgical or traditional endoscopic methods (ie, luminal stenting or decompressive gastrostomy) unfeasible. We demonstrated the novel use of EUS-guided lumen-apposing metal stent placement for enterocolonic bypass in patients with malignant SBO who were deemed high risk for surgery. METHODS: Across 3 tertiary U.S. centers, a retrospective series of consecutive patients underwent attempted EUS-guided enterocolostomy (EUS-EC) for palliation of acute SBO because of malignant causes. Technique and devices used were described, and patient demographics and outcome data were collected. RESULTS: Ten patients were included, of whom 9 (90.0%) were men, with a mean age of 64.5 ± 14.0 years and who were 1.5 ± 2.1 years postdiagnosis. Technical success was achieved in 8 of 10 patients (80.0%) and clinical success in 7 of 10 (70.0%), with a single major adverse event (10.0%) of aspiration. Median time until resumption of oral intake was 1.0 day (range, 0-8) after the procedure, with an interval to discharge home of 6.5 days and survival of 57.0 days. CONCLUSIONS: EUS-EC is a new alternative for palliation of acute SBO because of advanced malignant disease when conservative measures fail and other surgical or endoscopic options are not possible. Additional larger studies with longer duration of follow-up are needed to further define efficacy and safety of this approach.

BACKGROUND AND AIMS: EUS-directed transgastric intervention (EDGI) is an established technique for the management of pancreaticobiliary pathology in Roux-en-Y gastric bypass (RYGB) patients. There is an inherent risk of intraprocedural stent dislodgement, leading to perforation. The procedure is therefore often performed in 2 stages, 2 to 4 weeks apart, to allow for fistula maturation to mitigate the risk of lumen-apposing metal stent (LAMS) dislodgment. However, some clinical indications such as cholangitis require more urgent intervention, rendering this approach impractical. The aim of this study was to evaluate the safety and efficacy of same-session (SS)-EDGI with fixation of a 20-mm LAMS using endoscopic suturing. METHODS: This was a 2-center, retrospective study of consecutive RYGB patients who underwent SS-EDGI using a sutured 20-mm LAMS between February 2018 and May 2020. Patient demographics, procedural details, and clinical outcomes were recorded. RESULTS: Thirty-seven patients (mean age, 58.1 years; 86.5% women) underwent SS-EDGI with a median follow-up of 31.8 months. The procedural intervention was ERCP in 33 patients (89.2%) and ERCP with EUS in 4 patients (10.8%). Technical success was 100%. Access was achieved through the gastrogastric fistula in 26 patients (70.3%) and the jejunogastric fistula in 11 (29.7%). The LAMS was anchored with 2 endoscopic sutures in 33 patients (89.2%) and 1 suture in 4 (10.8%). Adverse events occurred in 4 patients (10.8%; 3 postprocedural bleeding, 1 cholangitis). There were no episodes of stent dislodgement or delayed stent migration. A persistent fistula was diagnosed in 7 patients (18.9%) who underwent objective testing (n = 28, 75.7%), of which 6 were successfully closed endoscopically. CONCLUSIONS: Single-stage EDGI using a sutured 20-mm LAMS was associated with a high rate of technical success, low rates of adverse events, and no episodes of stent migration. Persistent fistulas, although common, were amenable to endoscopic management.

BACKGROUND AND AIMS: Fully covered self-expandable metal stents (FCSEMSs) may offer a treatment option for pain associated with a dilated pancreatic duct (PD) in chronic pancreatitis (CP), but optimal patient selection and FCSEMS design, efficacy, and safety remain uncertain. We studied an investigational pancreatic FCSEMS for treatment of CP-associated pain. METHODS: Patients with painful CP, a dominant distal PD stricture, and PD dilation upstream were enrolled in a prospective, multicenter, single-arm trial studying 6-month indwell of a 4- to 6-cm-long soft pancreatic FCSEMS. Primary efficacy and safety endpoints were pain reduction 6 months after FCSEMS indwell (performance goal ≥53%) and PD stenting-related serious adverse events (SAEs), respectively (performance goal <32%). The primary efficacy endpoint was assessed in patients with sufficiently severe and frequent pain at FCSEMS placement as a first stent or in exchange of a plastic stent. RESULTS: Among 67 patients (mean age, 52.7 ± 12.5 years; mean time since CP diagnosis, 6.4 ± 6.4 years), 34 (50.7%) had plastic stent placement within 90 days of FCSEMS placement, and 46 patients were eligible for the primary efficacy endpoint analysis. Technical success was 97.0% (65/67). The observed primary efficacy (26.1%, 12/46) and safety endpoints (31.3%, 21/67) failed to meet the a priori study hypotheses. Study stent migration occurred in 47.7% of patients (31/65). CONCLUSIONS: Six-month treatment with an FCSEMS did not lead to an expected degree of pain reduction, and migrations and SAEs were common. Further study is needed to clarify optimal decompressive strategy, FCSEMS design, and patient selection. (Clinical trial registration number: NCT02802020.).

BACKGROUND AND AIMS: EUS-directed transgastric ERCP (EDGE) is an established method for managing pancreaticobiliary pathology in Roux-en-Y gastric bypass patients, with high rates of technical success and low rates of serious adverse events (AEs). However, widespread adoption of the technique has been limited because of concerns about the development of persistent gastrogastric or jejunogastric fistulas. Gastrogastric and jejunogastric fistulas have been reported in up to 20% of cases in some series, but predictive risk factors and long-term management and outcomes are lacking. Therefore, our aims were to assess factors associated with the development of persistent fistulas and the technical success of endoscopic fistula closure. METHODS: This is a case-control study involving 9 centers (8 USA, 1 Europe) from February 2015 to September 2021. Cases of persistent fistulas were defined as endoscopic or imaging evidence of fistula more than 8 weeks after lumen-apposing metal stent (LAMS) removal. Control subjects were defined as endoscopic or imaging confirmation of no fistula more than 8 weeks after LAMS removal. AEs were defined and graded according to the American Society for Gastrointestinal Endoscopy lexicon. RESULTS: Twenty-five patients identified to have evidence of a persistent fistula on follow-up surveillance (cases) were matched with 50 patients with no evidence of a persistent fistula on follow-up surveillance (control subjects) based on age and sex. Mean LAMS dwell time was 74.7 ± 106.2 days. After LAMS removal, argon plasma coagulation (APC) ablation of the fistula was performed in 46 patients (61.3%). Primary closure of the fistula was performed in 26.7% of patients (20: endoscopic suturing in 17, endoscopic tacking in 2, and over-the-scope clips + endoscopic suturing in 1). When comparing cases with control subjects, there was no difference in baseline demographics, fistula site, LAMS size, or primary closure frequency between the 2 groups (P > .05). However, in the persistent fistula group, the mean LAMS dwell time was significantly longer (127 vs 48 days, P = .02) and more patients had ≥5% total body weight gain (33.3% vs 10.3%, P = .03). LAMS dwell time was a significant predictor of persistent fistula (odds ratio, 4.5 after >40 days in situ, P = .01). The odds of developing a persistent fistula increased by 9.5% for every 7 days the LAMS was left in situ. In patients with a persistent fistula, endoscopic closure was attempted in 19 (76%) with successful resolution in 14 (73.7%). CONCLUSIONS: Longer LAMS dwell time was found to be associated with a higher risk of persistent fistulas in EDGE patients. APC or primary closure of the fistula on LAMS removal was not found to be protective against developing a persistent fistula, which, if present, can be effectively managed through endoscopic closure in most cases.

BACKGROUND AND AIMS: Palliation of malignant gastric outlet obstruction (mGOO) allows resumption of peroral intake. Although surgical gastrojejunostomy (SGJ) provides durable relief, it may be associated with a higher morbidity, interfere with chemotherapy, and require an optimum nutritional status. EUS-guided gastroenterostomy (EUS-GE) has emerged as a minimally invasive alternative. We aimed to conduct the largest comparative series to date between EUS-GE and SGJ for mGOO. METHODS: This multicenter retrospective study included consecutive patients undergoing SGJ or EUS-GE at 6 centers. Primary outcomes included time to resumption of oral intake, length of stay (LOS), and mortality. Secondary outcomes included technical and clinical success, reintervention rates, adverse events (AEs), and resumption of chemotherapy. RESULTS: A total of 310 patients were included (EUS-GE, n = 187; SGJ, n = 123). EUS-GE exhibited significantly lower time to resumption of oral intake (1.40 vs 4.06 days, P < .001), at lower albumin levels (2.95 vs 3.33 g/dL, P < .001), and a shorter LOS (5.31 vs 8.54 days, P < .001) compared with SGJ; there was no difference in mortality (48.1% vs 50.4%, P = .78). Technical (97.9% and 100%) and clinical (94.1% vs 94.3%) success was similar in the EUS-GE and SGJ groups, respectively. EUS-GE had lower rates of AEs (13.4% vs 33.3%, P < .001) but higher reintervention rates (15.5% vs 1.63%, P < .001). EUS-GE patients exhibited significantly lower interval time to resumption of chemotherapy (16.6 vs 37.8 days, P < .001). Outcomes between the EUS-GE and laparoscopic (n = 46) surgical approach showed that EUS-GE had shorter interval time to initiation/resumption of oral intake (3.49 vs 1.46 days, P < .001), decreased LOS (9 vs 5.31 days, P < .001), and a lower rate of AEs (11.9% vs 17.9%, P = .003). CONCLUSIONS: This is the largest study to date showing that EUS-GE can be performed among nutritionally deficient patients without affecting the technical and clinical success compared with SGJ. EUS-GE is associated with fewer AEs while allowing earlier resumption of diet and chemotherapy.

BACKGROUND: Endoscopic ultrasound-guided rendezvous (EUS-RV) endoscopic retrograde cholangiopancreatography (ERCP) is an alternative to interventional radiology-guided rendezvous ERCP in patients who failed biliary cannulation with conventional ERCP. However, there is significant variation in reported rates of success and adverse events associated with EUS-RV-assisted ERCP. We performed a systematic review and a proportion meta-analysis to reliably assess the effectiveness and safety of the EUS-RV-assisted ERCP. MATERIALS AND METHODS: We conducted a comprehensive search of multiple electronic databases and conference proceedings (from inception through August 2020) to identify studies reporting EUS-RV-assisted ERCP in patients who failed biliary cannulation with conventional ERCP techniques. Using the random-effects model described by DerSimonian and Laird, we calculated the pooled rates of technical success, clinical success, and adverse events of EUS-RV-assisted ERCP. RESULTS: Twelve studies reporting a total of 342 patients were included in the meta-analysis. The pooled rate of technical success (12 studies reporting a total of 342 patients) was 86.1% [95% confidence interval (CI): 78.4-91.3]. The pooled rate of clinical success (4 studies reporting a total of 94 patients) was 80.8% (95% CI: 64.1-90.8). The pooled rate of overall adverse events (12 studies; 42 events in 342 patients) was 14% (95% CI: 10.5-18.4). Low to moderate heterogeneity was noted in the analyses. CONCLUSIONS: EUS-RV-assisted ERCP appears to be effective and safe in patients who failed biliary cannulation with conventional ERCP. Given the risk of adverse events, it should be performed in centers with expertise in therapeutic endoscopic ultrasound.

BACKGROUND: Necrotizing pancreatitis can be complicated by Necrotic Fluid Collections (NFC). Guidelines recommend waiting for 4 weeks from the onset of acute pancreatitis (AP) before considering endoscopic drainage. We aimed to compare outcomes and safety in patients undergoing early versus late drainage of NFC. METHODS: We performed a retrospective review of all patients who underwent Dual Modality Drainage (DMD) [combined endoscopic and percutaneous drainage] for NFC from January 2007 to December 2020. Patients were stratified into the "early" group (DMD < 28 days from AP onset) and were matched to "late" (DMD ≥ 28 days) drainage group using propensity- core-matching. Primary outcomes of interest were technical success and adverse events. Secondary outcomes included clinical success, late complication rates, and mortality. RESULTS: We identified 278 patients who underwent DMD for NFC. Thirty-nine belonged to the early group and were matched to 174 patients from the late group. Technical success was similar in both early and late groups (97.4% vs 99.4%: P = 0.244) as were the procedural and early post-procedural (< 14 days) adverse events rates (23.1% vs 27.6%: P = 0.565). Clinical success (92.3% vs 93.1%; P = 0.861) and late complication rates (23.1% vs 31.6%; P = 0.294) were similar. There were 2 deaths (5.7%) in the early vs. 9 (5.2%) in the late group, P = 0.991. CONCLUSIONS: When performed in a tertiary care center with expertise in therapeutic endoscopic ultrasound, early drainage of NFC appears to be feasible and safe. Further studies are needed to validate our results.

BACKGROUND AND AIMS: Placement of a lumen-apposing metal stent (LAMS) between the gastric pouch and the excluded stomach allows for EUS-guided transgastric interventions (EDGIs) in patients with Roux-en-Y gastric bypass (RYGB). Although EUS-guided transgastric ERCP (EDGE) outcomes have been reported, data are scant on other endoscopic interventions. We aimed to evaluate the outcomes and safety of EDGIs. METHODS: This retrospective study involved 9 centers (United States, 8; Europe, 1) and included patients with RYGB who underwent EDGIs between June 2015 and September 2021. The primary outcome was the technical success of EDGIs. Secondary outcomes were adverse events (AEs), length of hospital stay, and fistula follow-up and management. RESULTS: Fifty-four EDGI procedures were performed in 47 patients (mean age, 61 years; 72% women), most commonly for the evaluation of a pancreatic mass (n = 16) and management of pancreatic fluid collections (n = 10). A 20-mm LAMS was used in 26 patients and a 15-mm LAMS in 21, creating a gastrogastrostomy in 37 patients and jejunogastrostomy in 10. Most patients (n = 30, 64%) underwent a dual-session EDGI, with a median interval of 17 days between the 2 procedures. Single-session EDGI was performed in 17 patients, of whom 10 (59%) had anchoring of the LAMS. The most common interventions were diagnostic EUS (with or without FNA or fine-needle biopsy sampling; n = 28) and EUS-guided cystgastrostomy (n = 8). The mean procedural time was 97.6 ± 78.9 minutes. Technical success was achieved in 52 patients (96%). AEs occurred in 5 patients (10.6%), of which only 1 AE (2.1%) was graded as severe. Intraprocedural LAMS migration was the most common AE, occurring in 3 patients (6.4%), whereas delayed spontaneous LAMS migration occurred in 2 (4.3%). Four of the 5 LAMS migration events were managed endoscopically, and 1 required surgical repair. LAMS anchoring was found to be protective against LAMS migration (P = .001). The median duration of hospital stay was 2.1 ± 3.7 days. Of the 17 patients who underwent objective fistula assessment endoscopically or radiologically after LAMS removal, 2 (11.7%) were found to have persistent fistulas. In 1 case the fistula was intentionally left open to assist with weight gain. The other fistula was successfully closed endoscopically. CONCLUSIONS: EDGI is effective and safe for the diagnosis and management of pancreaticobiliary and foregut disorders in RYGB patients. It is associated with high rates of technical success and low rates of severe AEs. LAMS migration is the most common AE with evidence that anchoring can be protective against its occurrence. Persistent fistulas may occur, but endoscopic closure seems to be effective.

BACKGROUND AND AIMS: Stent misdeployment (SM) has hindered the dissemination of EUS-guided gastroenterostomy (EUS-GE) for gastric outlet obstruction (GOO) management. We aimed to provide a classification system for SM during EUS-GE and study clinical outcomes and management accordingly. METHODS: This is a retrospective study involving 16 tertiary care centers (8 in the United States, 8 in Europe) from March 2015 to December 2020. Patients who developed SM during EUS-GE for GOO were included. We propose classifying SM into 4 types. The primary outcome was rate and severity of SM (per American Society for Gastrointestinal Endoscopy lexicon), whereas secondary outcomes were clinical outcomes and management of dislodgement according to the SM classification type, in addition to salvage management of GOO after SM. RESULTS: From 467 EUS-GEs performed for GOO during the study period, SM occurred in 46 patients (9.85%). Most SMs (73.2%) occurred during the first 13 EUS-GE cases by the performing operators. SM was graded as mild (n = 28, 60.9%), moderate (n = 11, 23.9%), severe (n = 6, 13.0%), or fatal (n = 1, 2.2%), with 5 patients (10.9%) requiring surgical intervention. Type I SM was the most common (n = 29, 63.1%), followed by type II (n = 14, 30.4%), type IV (n = 2, 4.3%), and type III (n = 1, 2.2%). Type I SM was more frequently rated as mild compared with type II SM (75.9% vs 42.9%, P = .04) despite an equivalent rate of surgical repair (10.3% vs 7.1%, P = .7). Overall, 4 patients (8.7%) required an intensive care unit stay (median, 2.5 days). The median length of stay was 4 days after SM. CONCLUSIONS: Although SM is not infrequent during EUS-GE, most are type I, mild/moderate in severity, and can be managed endoscopically with a surgical intervention rate of approximately 11%.

BACKGROUND: Endoscopic resection of lesions involving the appendiceal orifice remains a challenge. We aimed to report outcomes with the full-thickness resection device (FTRD) for the resection of appendiceal lesions and identify factors associated with the occurrence of appendicitis. METHODS: This was a retrospective study at 18 tertiary-care centers (USA 12, Canada 1, Europe 5) between November 2016 and August 2020. Consecutive patients who underwent resection of an appendiceal orifice lesion using the FTRD were included. The primary outcome was the rate of R0 resection in neoplastic lesions, defined as negative lateral and deep margins on post-resection histologic evaluation. Secondary outcomes included the rates of: technical success (en bloc resection), clinical success (technical success without need for further surgical intervention), post-resection appendicitis, and polyp recurrence. RESULTS: 66 patients (32 women; mean age 64) underwent resection of colonic lesions involving the appendiceal orifice (mean [standard deviation] size, 14.5 (6.2) mm), with 40 (61â%) being deep, extending into the appendiceal lumen. Technical success was achieved in 59/66 patients (89â%), of which, 56 were found to be neoplastic lesions on post-resection pathology. Clinical success was achieved in 53/66 (80â%). R0 resection was achieved in 52/56 (93â%). Of the 58 patients in whom EFTR was completed who had no prior history of appendectomy, appendicitis was reported in 10 (17â%), with six (60â%) requiring surgical appendectomy. Follow-up colonoscopy was completed in 41 patients, with evidence of recurrence in five (12â%). CONCLUSIONS: The FTRD is a promising non-surgical alternative for resecting appendiceal lesions, but appendicitis occurs in 1/6 cases.

BACKGROUND: Endoscopic therapy with endoscopic retrograde cholangiopancreatography is considered the first-line treatment in the management of post-cholecystectomy bile leak (PCBL). Currently, there is no consensus on the most effective endoscopic intervention for PCBL. Hence, we performed a systematic review and meta-analysis to compare the effectiveness and safety of the two interventional groups (biliary sphincterotomy [BS] alone vs. biliary stent ± BS) in management of PCBL. METHODS: We conducted a comprehensive search of multiple electronic databases and conference proceedings (from inception through January 2021). The primary outcome was to compare the pooled rate of clinical success between the 2 groups. The secondary outcome was to estimate the pooled rate of adverse events. RESULTS: The pooled rate of clinical success with BS alone (5 studies, 299 patients) was 88% (95% confidence interval (CI): 84-92%, I2: 0%) and for biliary stent ± BS (5 studies, 864 patients) was 97% (CI: 93-100%, I2: 79%). The rate of clinical success in biliary stent ± BS group was significantly higher than BS alone group (OR: 3.91 95% CI: 2.29-6.69, p < 0.001, I2: 13%). The rate of adverse events was numerically lower in biliary stent ± BS group compared to BS alone (3 studies; OR: 0.65 95% CI: 0.41-1.03, p = 0.07) without statistical significance. Low heterogeneity was noted in the analysis. CONCLUSIONS: Biliary stent ± BS is more effective in endoscopic management of PCBL compared to BS alone. This may be related to inter-endoscopist variation in completeness of sphincterotomy and post-sphincterotomy edema, which can influence the preferential trans-papillary flow of bile.

BACKGROUND: Although released only for drainage of pseudocyst and walled-off necrosis (WON) with ≤ 30% solid debris, the utilization of lumen-apposing metal stent (LAMS) in "real-world" practice has deviated from approved indications. We evaluated the contemporary use of LAMS and associated clinical, procedural outcomes in the setting of a tertiary referral center in the USA. METHODS: Data from 303 consecutive patients who underwent LAMS placement were analyzed. Outcomes included technical and clinical success rates and adverse events. RESULTS: Of 303 patients, 190 (62.7%) received LAMS for off-label indications. The latter included gallbladder drainage (n = 56, 18.5%), gastroenterostomy (n = 52, 17.2%), treatment of gastrointestinal strictures (n = 37, 12.2%), biliary drainage (n = 20, 6.6%), temporary gastric access for endoscopy (n = 13, 4.3%), symptomatic WON with > 30% solid debris (n = 8, 2.6%), and miscellaneous (n = 4, 1.3%). Technical success rates in the on- and off-label arm were 98.2% and 95.8%, respectively (P = .331; 95% CI 0.08 to 1.96). Clinical success rates in the on- and off-label arm were 89.4% and 83.2%, respectively (P = .137; 95% CI 0.28 to 1.19). The rate of adverse events was 20.5% (n = 39) in the off-label arm and 16.8% (n = 19) in the on-label arm (P = .242; 95% CI 0.69 to 2.34). CONCLUSION: Off-label use of LAMS out-numbered on-label use in our practice. The safety profile between the groups was similar and with the exception of refractory stricture treatment, efficacy was comparable.

BACKGROUND: Fluoroscopy is often used for endoscopic balloon dilation (EBD) of Crohn's disease (CD)-related strictures. However, its benefit remains unclear. AIMS: To compare EBD with (EBDF) and without (EBDNF) fluoroscopic guidance in CD patients with strictures. METHODS: Single-center, nested, case-control retrospective study of EBD for CD-related strictures. Technical and clinical success and safety outcomes were compared between EBDF and EBDNF. RESULTS: A total of 122 strictures in 114 CD patients who underwent EBD from 2010 to 2018 at a single institution were reviewed (44 patients EBDF vs. 70 EBDNF). Esophagogastroduodenoscopy was the approach in 8 strictures, colonoscopy in 86, and deep enteroscopy in 28. There were no significant differences in the rates of technical and clinical success, need for repeat dilation and surgery between the two groups, although the mean maximal endoscopic balloon diameter was larger in the EBDNF group (17.1 ± 1.9 vs. 14.1 ± 2.5; p < 0.001). There was one perforation in EBDF and no serious complications in EBDNF. In multivariate analysis, balloon size < 15 mm (odds ratio [OR] 6.388; 95% CI 1.96-20.79; p = 0.002) and multiple strictures (OR 3.897; 95% CI 1.09-14.01; p = 0.037) were associated with repeat EBD, and age < 50 years (OR 7.178; 95% CI 1.38-37.44; p = 0.019) and small bowel (vs. colon) location (OR 7.525; 95% CI 1.51-37.47; p = 0.014) were associated with the need for surgery after EBD. CONCLUSIONS: EBD for CD-related strictures can be performed safely and effectively without fluoroscopic guidance. Balloon size, patient age, stricture location, and multiplicity are associated with clinical success and avoidance of surgery.

BACKGROUND AND AIMS: Therapeutic endoscopy plays a critical role in the management of upper GI (UGI) postsurgical leaks. Data are scarce regarding clinical success and safety. Our aim was to evaluate the effectiveness of endoscopic therapy for UGI postsurgical leaks and associated adverse events (AEs) and to identify factors associated with successful endoscopic therapy and AE occurrence. METHODS: This was a retrospective, multicenter, international study of all patients who underwent endoscopic therapy for UGI postsurgical leaks between 2014 and 2019. RESULTS: Two hundred six patients were included. Index surgery most often performed was sleeve gastrectomy (39.3%), followed by gastrectomy (23.8%) and esophagectomy (22.8%). The median time between index surgery and commencement of endoscopic therapy was 16 days. Endoscopic closure was achieved in 80.1% of patients after a median follow-up of 52 days (interquartile range, 33-81.3). Seven hundred seventy-five therapeutic endoscopies were performed. Multimodal therapy was needed in 40.8% of patients. The cumulative success of leak resolution reached a plateau between the third and fourth techniques (approximately 70%-80%); this was achieved after 125 days of endoscopic therapy. Smaller leak initial diameters, hospitalization in a general ward, hemodynamic stability, absence of respiratory failure, previous gastrectomy, fewer numbers of therapeutic endoscopies performed, shorter length of stay, and shorter times to leak closure were associated with better outcomes. Overall, 102 endoscopic therapy-related AEs occurred in 81 patients (39.3%), with most managed conservatively or endoscopically. Leak-related mortality rate was 12.4%. CONCLUSIONS: Multimodal therapeutic endoscopy, despite being time-consuming and requiring multiple procedures, allows leak closure in a significant proportion of patients with a low rate of severe AEs.

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 >â50â% within 2 weeks. RESULTS: 28 patients were included, with a lumen-apposing metal stent used in 26 (93â%) and a self-expandable metal stent in two (7â%). The technical success rate was 100â%. The clinical success rate was 93â%, with an improvement in bilirubin (7.3 [SD 5.4] pre-procedure vs. 2.8 [SD 1.1] post-procedure; Pâ=â0.001). Delayed adverse events included food impaction of the stent (nâ=â3), 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.

BACKGROUND: Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP; EDGE) is an alternative to enteroscopy- and laparoscopy-assisted ERCP in patients with Roux-en-Y gastric bypass anatomy. Although short-term results are promising, the long-term outcomes are not known. The aims of this study were: (1) to determine the rates of long-term adverse events after EDGE, with a focus on rates of persistent gastrogastric or jejunogastric fistula; (2) to identify predictors of persistent fistula; (3) to assess the outcomes of endoscopic closure when persistent fistula is encountered. METHODS: This was a multicenter retrospective study involving 13 centers between February 2015 and March 2019.âAdverse events were defined according to the ASGE lexicon. Persistent fistula was defined as an upper gastrointestinal series or esophagogastroduodenoscopy showing evidence of fistula. RESULTS: 178 patients (mean age 58 years, 79â% women) underwent EDGE. Technical success was achieved in 98â% of cases (175/178), with a mean procedure time of 92 minutes. Periprocedural adverse events occurred in 28 patients (15.7â%; mild 10.1â%, moderate 3.4â%, severe 2.2â%). The four severe adverse events were managed laparoscopically. Persistent fistula was diagnosed in 10â% of those sent for objective testing (9/90). Following identification of a fistula, 5â/9 patients underwent endoscopic closure procedures, which were successful in all cases. CONCLUSIONS: The EDGE procedure is associated with high clinical success rates and an acceptable risk profile. Persistent fistulas after lumen-apposing stent removal are uncommon, but objective testing is recommended to identify their presence. When persistent fistulas are identified, endoscopic treatment is warranted, and should be successful in closing the fistula.
