RESUMO
INTRODUCTION: Guidelines endorse pancreatic cancer screening in genetically susceptible individuals. We conducted a prospective, multicenter study to determine yield, harms, and outcomes of pancreatic cancer screening. METHODS: All high-risk individuals undergoing pancreatic cancer screening at 5 centers from 2020 to 2022 were prospectively enrolled. Pancreas findings were designated as low-risk (fatty or chronic pancreatitis-like changes), intermediate-risk (neuroendocrine tumor [NET] <2 cm or branch-duct intraductal papillary mucinous neoplasm [IPMN]), or high-risk lesions (high-grade pancreatic intraepithelial neoplasia/dysplasia, main-duct IPMN, NET >2 cm, or pancreatic cancer). Harms from screening included adverse events during screening or undergoing low-yield pancreatic surgery. Annual screening was performed using endoscopic ultrasound and or magnetic resonance cholangiopancreatography. Annual screening for new-onset diabetes using fasting blood sugar was also performed ( ClinicalTrials.gov : NCT05006131). RESULTS: During the study period, 252 patients underwent pancreatic cancer screening. Mean age was 59.9 years, 69% were female, and 79.4% were White. Common indications were BRCA 1/2 (36.9%), familial pancreatic cancer syndrome kindred (31.7%), ataxia telangiectasia mutated (3.5%), Lynch syndrome (6.7%), Peutz-Jeghers (4.3%), and familial atypical multiple mole melanoma (3.5%). Low-risk lesions were noted in 23.4% and intermediate-risk lesions in 31.7%, almost all of which were branch-duct IPMN without worrisome features. High-risk lesions were noted in 2 patients (0.8%), who were diagnosed with pancreas cancer at stages T2N1M0 and T2N1M1. Prediabetes was noted in 18.2% and new-onset diabetes in 1.7%. Abnormal fasting blood sugar was not associated with pancreatic lesions. There were no adverse events from screening tests, and no patient underwent low-yield pancreatic surgery. DISCUSSION: Pancreatic cancer screening detected high-risk lesions with lower frequency than previously reported. No harms from screening were noted.

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: 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: A small percentage of patients with esophageal dysmotility disorders (EDDs) fail to improve or relapse after management by laparoscopic Heller myotomy (LHM) and peroral endoscopic myotomy (POEM). In this study, we aimed to describe the role of functional luminal imaging probe (FLIP) in identifying patients who might benefit from lower esophageal sphincter (LES)-directed retreatment. METHODS: This was a retrospective study at 6 tertiary care centers (United States, 4; Europe, 1; Asia, 1) between January 2015 and April 2021 involving patients with prior failed myotomy. The primary outcome was the impact of the use of FLIP on the management of patients with prior failed myotomy. RESULTS: One hundred twenty-three patients (62 women [50%]; mean age, 53 ± 21.1 years) who underwent LHM (n = 53, 43%) or POEM (n = 70, 57%) for the management of achalasia (n = 98) or other EDDs (n = 25) had clinical failure at a median time of 10.8 months (interquartile range, .8-17.3) postprocedure. Twenty-nine patients had apposing "abnormal" diagnoses in terms of integrated relaxation pressure (IRP) >15 mm Hg on HRM and distensibility index (DI) <2.8 mm2/mm Hg on FLIP, with ultimate change in management noted in 15 patients (10 directed toward conservative management, 5 directed toward LES-directed retreatment). The impact of FLIP on both diagnosis and management was noted in 15 of 29 patients (52%). In the subgroup analysis of 44 patients who underwent LES-directed retreatment, clinical success was highest among patients with both abnormal IRP and DI (21/25 [84%]) versus patients with only abnormal IRP (8/14 [57%]) or only abnormal DI (3/5 [60%], P = .04), with DI at 40-mL distension volume on FLIP identified as an independent predictor of clinical success (odd ratio, 1.51; 95% confidence interval, 1.02-2.1; P = .03). CONCLUSIONS: The finding of this study further suggests the important role of using FLIP in addition to HRM in evaluating patients with clinical failure postmyotomy.

BACKGROUND: Endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections (PFCs) by cautery-enhanced lumen-apposing metal stents (LAMS) has largely been limited to collections located <â10âmm from the luminal wall. We present outcomes of the use of a novel 15-mm-long cautery-enhanced LAMS for drainage of PFCs located ≥â10âmm away. METHODS: This international, multicenter study analyzed all adults with PFCs located ≥â10âmm from the luminal wall who were treated by EUS-guided drainage using the 15-mm-long cautery-enhanced LAMS. The primary outcome was technical success. Secondary outcomes included clinical success (decrease in PFC size byâ≥â50â% at 30 days and resolution of clinical symptoms without surgical intervention), complications, and recurrence. RESULTS: 35 patients (median age 57 years; interquartile range [IQR] 47-64 years; 49â% male) underwent novel LAMS placement for drainage of PFCs (26 walled-off necrosis, 9 pseudocysts), measuring 85âmm (IQR 64-117) maximal diameter and located 11.8âmm (IQR 10-12.3; range 10-14) from the gastric/duodenal wall. Technical and clinical success were high (both 97â%), with recurrence in one patient (3â%) at a median follow-up of 123 days (58-236). Three complications occurred (9â%; one mild, two moderate). CONCLUSIONS: The 15-mm-long cautery-enhanced LAMS was feasible and safe for drainage of PFCs located 10-14âmm from the luminal wall.

BACKGROUND: Most studies on endoscopic ultrasound (EUS)-guided gastroenterostomy (EUS-GE) for palliation of malignant gastric outlet obstruction (GOO) utilized a 15-mm lumen-apposing metal stent (LAMS). More recently, a 20-mm LAMS has become available. This study aimed to compare rates of technical and clinical success and adverse events (AEs) in patients undergoing EUS-GE using a 20-mm vs. 15-mm LAMS. METHODS: Patients who underwent EUS-GE with 15-mm or 20-mm LAMS for malignant GOO during the period from January 2018 to October 2020 were included. The primary outcome was clinical success, defined as an increase in the gastric outlet obstruction score (GOOS) by at least 1 point during follow-up.âSecondary outcomes were technical success, maximum tolerated diet, re-intervention rate, and rate/severity of AEs. RESULTS: 267 patients (mean age 67 years, 43â% women) with malignant GOO from 19 centers underwent EUS-GE. Clinical success rates were similar for the 15-mm and 20-mm stents (89.2â% [95â%CI 84.2â%-94.2â%] vs. 84.1â% [77.4%-90.6â%], respectively). However, a significantly higher proportion of patients in the 20-mm group tolerated a soft solid/complete diet at the end of follow-up (91.2â% [84.4â%-95.7â%] vs. 81.2â% [73.9â%-87.2â%], Pâ=â0.04). Overall, AEs occurred in 33 patients (12.4â% [8.4â%-16.3â%]), with similar rates for 15-mm and 20-mm stents (12.8â% [7.5â%-18.2â%] vs. 11.8â% [6â%-17.6â%]), including incidence of severe/fatal AEs (2â% [0.4â%-5.8â%] vs. 3.4â% [0.9â%-8.4â%]). CONCLUSIONS: The 20-mm and 15-mm LAMS show similar safety and efficacy for patients undergoing EUS-GE for malignant GOO. The 20-mm LAMS allows a more advanced diet and is, thus preferred for EUS-GE.

OBJECTIVES: Disconnected pancreatic duct syndrome (DPDS) is the most common cause of pancreatic fluid collection (PFC) recurrence. While long-term transmural drainage with plastic stents is the preferred endoscopic approach, there is a paucity of literature on patients undergoing initial drainage with lumen-apposing metal stents (LAMS). We describe our experience managing patients with DPDS. METHODS: A retrospective review of a prospectively maintained database (November 2015-September 2020) was performed looking at clinical outcomes and overall survival for patients undergoing endoscopic management of PFCs using LAMS. The primary outcome was to assess recurrence-free survival in PFC patients with DPDS managed with or without double pigtail stents (DPS) replacement after LAMS removal. RESULTS: Of 96 patients with PFCs, 48 with DPDS were included in the study. The median follow-up was 20.1 months. LAMS replacement with DPS was successful in 21/48 (43.8%) patients. Recurrence was seen in 1/21 (5%) patients with DPS replacement and 10/27 (37%) without DPS replacement. In multivariable models, a longer duration of LAMS placement was negatively associated with successful DPS replacement (odds ratio 1.33, 95% confidence interval [CI] 1.11, 1.59, P = 0.0019) and successful LAMS replacement with DPS in patients with DPDS improved recurrence-free survival (hazard ratio 0.09, 95% CI 0.01, 0.83, P = 0.033). CONCLUSION: In patients with PFCs and DPDS, early replacement of LAMS with DPS improves the likelihood of successful long-term transmural drainage and decreases recurrences.

BACKGROUND & AIMS: The prevalence and significance of digestive manifestations in coronavirus disease 2019 (COVID-19) remain uncertain. We aimed to assess the prevalence, spectrum, severity, and significance of digestive manifestations in patients hospitalized with COVID-19. METHODS: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, laboratory assessment, imaging, and endoscopic findings from the time of symptom onset until discharge or death were abstracted manually from electronic health records to characterize the prevalence, spectrum, and severity of digestive manifestations. Regression analyses were performed to evaluate the association between digestive manifestations and severe outcomes related to COVID-19. RESULTS: A total of 1992 patients across 36 centers met eligibility criteria and were included. Overall, 53% of patients experienced at least 1 gastrointestinal symptom at any time during their illness, most commonly diarrhea (34%), nausea (27%), vomiting (16%), and abdominal pain (11%). In 74% of cases, gastrointestinal symptoms were judged to be mild. In total, 35% of patients developed an abnormal alanine aminotransferase or total bilirubin level; these were increased to less than 5 times the upper limit of normal in 77% of cases. After adjusting for potential confounders, the presence of gastrointestinal symptoms at any time (odds ratio, 0.93; 95% CI, 0.76-1.15) or liver test abnormalities on admission (odds ratio, 1.31; 95% CI, 0.80-2.12) were not associated independently with mechanical ventilation or death. CONCLUSIONS: Among patients hospitalized with COVID-19, gastrointestinal symptoms and liver test abnormalities were common, but the majority were mild and their presence was not associated with a more severe clinical course.

INTRODUCTION: Radiofrequency ablation (RFA) is an effective treatment modality for atrial fibrillation (AF); however, serious complications can occur. We present the case of a highly morbid consequence, the esophagopericardial fistula (EPF). CASE: A hemodynamically unstable patient with a history of AF and recent RFA presented with chest pain and was found to have pneumopericardium and pericardial effusion. The patient went to the operating room emergently for combined management with surgical pericardial window and endoscopic stent placement. CONCLUSION: EPF must be on the differential diagnosis while evaluating patients who develop constitutional symptoms or sudden onset chest pain days or weeks after catheter ablation for AF. Early detection followed by aggressive management with a combined surgical and endoscopic approach may be considered for successful treatment of this type of postablation esophageal perforation if an atrioesophageal fistula is effectively ruled out.

BACKGROUNDS: Endoscopic ultrasound (EUS)-guided placement of lumen-apposing metal stents (LAMSs) has gained popularity for the treatment of pancreatic walled-off necrosis (WON). We compared the 20-mm and 15-mm LAMSs for the treatment of symptomatic WON in terms of clinical success and adverse events. METHODS: We conducted a retrospective, case-matched study of 306 adults at 22 tertiary centers from 04/2014 to 10/2018. A total of 102 patients with symptomatic WON who underwent drainage with 20-mm LAMS (cases) and 204 patients who underwent drainage with 15-mm LAMS (controls) were matched by age, sex, and drainage approach. Conditional logistic regression analysis was performed to compare clinical success (resolution of WON on follow-up imaging without reintervention) and adverse events (according to American Society for Gastrointestinal Endoscopy criteria). RESULTS: Clinical success was achieved in 92.2â% of patients with 20-mm LAMS and 91.7â% of patients with 15-mm LAMS (odds ratio 0.92; Pâ=â0.91). Patients with 20-mm LAMS underwent fewer direct endoscopic necrosectomy (DEN) sessions (mean 1.3 vs. 2.1; Pâ<â0.001), despite having larger WON collections (transverse axis 118.2 vs. 101.9âmm, Pâ=â0.003; anteroposterior axis 95.9 vs. 80.1âmm, Pâ=â0.01). There was no difference in overall adverse events (21.6â% vs. 15.2â%; Pâ=â0.72) and bleeding events (4.9â% vs. 3.4â%; Pâ=â0.54) between the 20-mm and 15-mm LAMS groups, respectively. CONCLUSIONS: The 20-mm LAMS showed comparable clinical success and safety profile to the 15-mm LAMS, with the need for fewer DEN sessions for WON resolution.

BACKGROUND: Larger caliber lumen-apposing stents (LAMSs) have been increasingly used in the management of pancreatic fluid collections, specifically when solid debris is present; however, their advantages over smaller caliber plastic stents in the management of pancreatic pseudocysts are unclear. The aim of this study was to investigate the safety and efficacy of LAMS specifically in the management of pancreatic pseudocysts compared with double-pigtail plastic stents (DPPSs). METHODS: We performed a multicenter, international, retrospective study between January 2012 and August 2016.âA total of 205 patients with a diagnosis of pancreatic pseudocysts were included, 80 patients received LAMSs and 125 received DPPSs. Measured outcomes included clinical success, technical success, adverse events, stent dysfunction, pancreatic pseudocyst recurrence, and need for surgery. RESULTS: Technical success was similar between the LAMS and the DPPS groups (97.5â% vs. 99.2â%; Pâ=â0.32). Clinical success was higher for LAMSs than for DPPSs (96.3â% vs. 87.2â%; Pâ=â0.03). While the need for surgery was similar between the two groups (1.3â% vs. 4.9â%, respectively; Pâ=â0.17), the use of percutaneous drainage was significantly lower in the LAMS group (1.3â% vs. 8.8â%; Pâ=â0.03). At 6-month follow-up, the recurrence rate was similar between the groups (6.7â% vs 18.8â%, respectively; Pâ=â0.12). The rate of adverse events was significantly higher in the DPPS group (7.5â% vs. 17.6â%; Pâ=â0.04). There was no difference in post-procedure mean length of hospital stay (6.3 days [standard deviation 27.9] vs. 3.7 days [5.7]; Pâ=â0.31). CONCLUSION: When compared to DPPSs, LAMSs are a safe, feasible, and effective modality for the treatment of pancreatic pseudocysts and are associated with a higher rate of clinical success, shorter procedure time, less need for percutaneous interventions, and a lower overall rate of adverse events.

BACKGROUND: Multiple studies have examined the use of lumen-apposing metal stents (LAMSs) for the drainage of peripancreatic fluid collections. Data on the use of LAMSs for postoperative fluid collections (POFCs) are scarce. POFCs may lead to severe complications without appropriate treatment. We aimed to study the outcomes (technical success, clinical success, rate/severity of adverse events, length of stay, recurrence) of the use of LAMSs for the drainage of POFCs. METHODS: This international, multicenter, retrospective study involved 19 centers between January 2012 and October 2017. The primary outcome was clinical success. Secondary outcomes included technical success and rate/severity of adverse events using the ASGE lexicon. RESULTS: A total of 62 patients were included during the study period. The most common etiology of the POFCs was distal pancreatectomy (46.8â%). The mean (standard deviation) diameter was 84.5âmm (30.7âmm). The most common indication for drainage was infection (48.4â%) and transgastric drainage was the most common approach (82.3â%). Technical success was achieved in 60/62 patients (96.8â%) and clinical success in 57/62 patients (91.9â%) during a median (interquartile range) follow-up of 231 days (90â-â300 days). Percutaneous drainage was needed in 8.1â% of patients. Adverse events occurred intraoperatively in 1/62 patients (1.6â%) and postoperatively in 7/62 (11.3â%). There was no procedure-related mortality. CONCLUSION: This is the largest study on the use of LAMSs for POFCs. It suggests good clinical efficacy and safety of this approach. The use of LAMSs in the management of POFCs is a feasible alternative to percutaneous and surgical drainage.

BACKGROUND AND AIMS: The obesity epidemic has led to increased use of Roux-en-Y gastric bypass (RYGB). These patients have an increased incidence of pancreaticobiliary diseases, yet standard ERCP is not possible because of surgically altered gastroduodenal anatomy. Laparoscopy-assisted ERCP (LA-ERCP) has been proposed as an option, but supporting data are derived from single-center small case series. Therefore, we conducted a large multicenter study to evaluate the feasibility, safety, and outcomes of LA-ERCP. METHODS: This is a retrospective cohort study of adult patients with RYGB who underwent LA-ERCP in 34 centers. Data on demographics, indications, procedure success, and adverse events were collected. Procedure success was defined when all the following were achieved: reaching the papilla, cannulating the desired duct, and providing endoscopic therapy as clinically indicated. RESULTS: A total of 579 patients (median age, 51; 84% women) were included. Indication for LA-ERCP was biliary in 89%, pancreatic in 8%, and both in 3%. Procedure success was achieved in 98%. Median total procedure time was 152 minutes (interquartile range [IQR], 109-210), with a median ERCP time of 40 minutes (IQR, 28-56). Median hospital stay was 2 days (IQR, 1-3). Adverse events were 18% (laparoscopy related, 10%; ERCP related, 7%; both, 1%) with the clear majority (92%) classified as mild/moderate, whereas 8% were severe and 1 death occurred. CONCLUSIONS: Our large multicenter study indicates that LA-ERCP in patients with RYGB is feasible with a high procedure success rate comparable with that of standard ERCP in patients with normal anatomy. The ERCP-related adverse events rate is comparable with conventional ERCP, but the overall adverse event rate was higher because of the added laparoscopy-related events.

GOALS: The aim of this study was to characterize current trends in the use of endoscopic retrograde cholangiopancreatography (ERCP) in the United States for patients hospitalized with chronic pancreatitis. BACKGROUND: Historically, ERCP was the primary tool for diagnostic and therapeutic management of chronic pancreatitis. With increased availability of magnetic resonance imaging and endoscopic ultrasound, indications for ERCP are being redefined. STUDY: We performed a retrospective cohort study using the Nationwide Inpatient Sample from 1998 to 2010. We identified patients with a primary discharge diagnosis of chronic pancreatitis who underwent ERCP. We excluded patients diagnosed with biliary, gallbladder, or pancreatic neoplasm and patients who underwent gallbladder or pancreatic operation during the same admission. We analyzed patient and hospital characteristics, length of stay, and in-hospital mortality, and adjusted for weighted sample schema. RESULTS: During the study period, 29,318 patients with chronic pancreatitis (mean age 52 y, 57.2% female) underwent ERCP during their hospitalization. The majority of patients were white (56.1%). The majority of procedures were performed at large (72.4%), urban (95.2%), and academic (69.0%) hospitals. Mean hospital charges were $32,929 (SE= $1605). Mean length of stay was 6 days (SE=0.3), with in-hospital mortality of 0.76%. Over the study period, the number of procedures has decreased significantly (P<0.001). CONCLUSIONS: In the United States, ERCP has been an important diagnostic and therapeutic tool for chronic pancreatitis. Over the last decade, ERCP has become an uncommon inpatient procedure for chronic pancreatitis.
