Abstract
1: ESGE recommends a prolonged course of a prophylactic broad-spectrum antibiotic in patients with ascites who are undergoing therapeutic endoscopic ultrasound (EUS) procedures.Strong recommendation, low quality evidence. 2: ESGE recommends placement of partially or fully covered self-expandable metal stents during EUS-guided hepaticogastrostomy for biliary drainage in malignant disease.Strong recommendation, moderate quality evidence. 3: ESGE recommends EUS-guided pancreatic duct (PD) drainage should only be performed in high volume expert centers, owing to the complexity of this technique and the high risk of adverse events.Strong recommendation, low quality evidence. 4: ESGE recommends a stepwise approach to EUS-guided PD drainage in patients with favorable anatomy, starting with rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP), followed by antegrade or transmural drainage only when RV-ERP fails or is not feasible.Strong recommendation, low quality evidence. 5: ESGE suggests performing transduodenal EUS-guided gallbladder drainage with a lumen-apposing metal stent (LAMS), rather than using the transgastric route, as this may reduce the risk of stent dysfunction.Weak recommendation, low quality evidence. 6: ESGE recommends using saline instillation for small-bowel distension during EUS-guided gastroenterostomy.Strong recommendation, low quality evidence. 7: ESGE recommends the use of saline instillation with a 19G needle and an electrocautery-enhanced LAMS for EUS-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE) procedures.Strong recommendation, low quality evidence. 8: ESGE recommends the use of either 15- or 20-mm LAMSs for EDGE, with a preference for 20-mm LAMSs when considering a same-session ERCP.Strong recommendation, low quality evidence.

Abstract
OBJECTIVE In patients with an intermediate likelihood of choledocholithiasis, European Society of Gastrointestinal Endoscopy (ESGE) guidelines recommend endoscopic ultrasound (EUS) or magnetic resonance cholangiopancreatography (MRCP) to diagnose choledocholithiasis to make the indication for endoscopic retrograde cholangiopancreatography (ERCP) treatment; there is no randomised control trial to compare both in this setting. DESIGN Patients with suspected choledocholithiasis satisfying ESGE guideline's intermediate likelihood were screened for this single-centre randomised controlled trial between November 2019 and May 2020. The enrolled patients were randomised to either EUS or MRCP. ERCP was performed in stone positive cases or if clinical suspicion persisted during follow-up. Negative cases underwent a further 6-month clinical follow-up. Main outcome was accuracy (sensitivity/specificity) of both tests to diagnose choledocholithiasis, with ERCP or follow-up as a gold standard. RESULTS Of 266 patients, 224 patients (mean age: 46.77±14.57 years; 50.9 % female) were enrolled; overall prevalence of choledocholithiasis was 49.6%, with a higher frequency in the MRCP group (63/112 vs 46/112 for EUS). Both sensitivity of EUS and MRCP were similarly high (92%-98%), without significant differences between the two groups. The negative predictive value and likelihood ratio + were significantly higher in EUS arm (p<0.05). The percentage of ERCPs either incorrectly halted back (false negatives: EUS: 2 vs MRCP: 5) or performed unnecessarily (false positives: EUS: 1 vs MRCP: 2) was low in both groups. CONCLUSION The performance parameters of both EUS and MRCP are comparable for detecting choledocholithiasis in the intermediate-risk group of choledocholithiasis and the choice of a test should be based on local expertise, availability of resources and patient preference. TRIAL REGISTRATION NUMBER NCT04173624.

Abstract
1: ESGE recommends the use of endoscopic ultrasound-guided biliary drainage (EUS-BD) over percutaneous transhepatic biliary drainage (PTBD) after failed endoscopic retrograde cholangiopancreatography (ERCP) in malignant distal biliary obstruction when local expertise is available.Strong recommendation, moderate quality evidence. 2: ESGE suggests EUS-BD with hepaticogastrostomy only for malignant inoperable hilar biliary obstruction with a dilated left hepatic duct when inadequately drained by ERCP and/or PTBD in high volume expert centers.Weak recommendation, moderate quality evidence. 3: ESGE recommends that EUS-guided pancreatic duct (PD) drainage should only be considered in symptomatic patients with an obstructed PD when retrograde endoscopic intervention fails or is not possible.Strong recommendation, low quality evidence. 4: ESGE recommends rendezvous EUS techniques over transmural PD drainage in patients with favorable anatomy owing to its lower rate of adverse events.Strong recommendation, low quality evidence. 5: ESGE recommends that, in patients at high surgical risk, EUS-guided gallbladder drainage (GBD) should be favored over percutaneous gallbladder drainage where both techniques are available, owing to the lower rates of adverse events and need for re-interventions in EUS-GBD.Strong recommendation, high quality of evidence. 6: ESGE recommends EUS-guided gastroenterostomy (EUS-GE), in an expert setting, for malignant gastric outlet obstruction, as an alternative to enteral stenting or surgery.Strong recommendation, low quality evidence. 7: ESGE recommends that EUS-GE may be considered in the management of afferent loop syndrome, especially in the setting of malignancy or in poor surgical candidates. Strong recommendation, low quality evidence. 8: ESGE suggests that endoscopic ultrasound-directed transgastric ERCP (EDGE) can be offered, in expert centers, to patients with a Roux-en-Y gastric bypass following multidisciplinary decision-making, with the aim of overcoming the invasiveness of laparoscopy-assisted ERCP and the limitations of enteroscopy-assisted ERCP.Weak recommendation, low quality evidence.

Abstract
Introduction Biodegradable stents of various designs are reportedly used in pancreato-biliary conditions with promising results. Their major advantage is the avoidance of a repeat endoscopic procedure for stent removal thereby reducing overall cost along with ERCP associated adverse events. To evaluate the feasibility and safety of a new biodegradable stent in patients with pancreato-biliary diseases. Methods Prospective multicenter pilot study. All consecutive patients 18 years-old who underwent biliary or pancreatic stenting using the new biodegradable Archimedes stent were included. There were three biodegradation profiles. Technical and clinical success, feasibility and safety were assessed during a pre-established follow-up schedule. Results Fifty-three patients (mean age: 48.54±19.29, 66% male) having biliary (n=29, 54.7%%) or pancreatic (n=24, 45.3%) indications were included. The distribution of stents used according to degradation properties were as follows: fast (n=11, 20.8%), medium (n=16, 30.2%) and slow (n=26, 49.1%). The technical and clinical success were 100% and 77.8%. Thirty-five patients were followed for a median of 26 weeks (range: 4-56, 66%). There were 9 procedure-related adverse events (17%), all mild, including one uneventful stent-related event (external migration). Conclusion The biodegradable Archimedes stent placement is feasible and safe in pancreato-biliary diseases.

Abstract
Background and study aims Endoscopic ultrasound-guided gastro-enterostomy(EUS-GE) is a recently described novel minimally invasive endoscopic procedure for patients having malignant gastric outlet obstruction (GOO). The safety of EUS-GE in the presence of ascites with GOO is not known. The objective of the study was to evaluate the feasibility and safety of EUS-GE in patients with GOO and ascites. Patients and methods Consecutive patients with GOO who underwent EUS-GE between January 2019 and March 2021 constituted the study population. EUS-GE was performed using either EPASS or free-hand technique. The technical success, clinical success, adverse events, and survival times were evaluated. The outcomes were compared between patients with and without ascites. Results A total of 31 patients with GOO underwent EUS-GE of whom 29 (93.5 %) had malignant and two (6.4 %) had benign etiologies. Ascites was observed in 12 out of 31 (38.7%) patients and all had underlying malignancy. Majority (27, 87 %) of the EUS-GE procedures were performed using EPASS technique, and 4 (13 %) underwent free-hand technique. Eleven of 12 patients with ascites and GOO underwent EUS GE using EPASS technique. The technical success (91.6 % vs. 89.4 %; P = 0.841), clinical success (83.3 % vs. 89.4 %; P = 0.619), mean procedure time (32 vs. 31.6 min; P = 0.968) and adverse events (0 % vs. 10.5 %; P = 0.245) were not significantly different between patients with or without ascites. However, the median survival time was significantly low in patients with ascites when compared to without ascites (36 vs. 290 days; P < 001 ). Conclusions Ascites is a common occurrence in patients with malignant GOO. EUS GE is feasible in presence of ascites with EPASS technique.

Abstract
BACKGROUND Pancreatic cystic lesions (PCLs) are increasingly found on cross-sectional imaging, with the majority having a low risk for malignancy. The added value of fine-needle aspiration (FNA) in risk stratification remains unclear. We evaluated the impact of three FNA needles on diagnostic accuracy, clinical management, and the ability to accrue fluid for tumor markers. METHODS A multicenter prospective trial randomized 250 patients with PCLs ≥ 13 mm 2:1:1 to 19G Flex, 19G, and 22G needles with crossover for repeated FNA procedures. Diagnostic accuracy was established at 2-year follow-up, with the final diagnosis from surgical histopathology or consensus diagnosis by experts based sequentially on clinical presentation, imaging, and aspirate analysis in blinded review. RESULTS Enrolled patients (36 % symptomatic) had PCLs in the head (44 %), body (28 %), and tail (26 %). Percentage of cyst volume aspirated was 78 % (72 % - 84 %) for 19G Flex, 74 % (64 % - 84 %) for 22G, and 73 % (63 % - 83 %) for 19G (P = 0.84). Successful FNA was significantly higher for 19G Flex (89 % [82 % - 94 %]) and 22G (82 % [70 % - 90 %]) compared with 19G (75 % [63 % - 85 %]) (P = 0.02). Repeated FNA was required more frequently in head/uncinate lesions than in body and tail (P < 0.01). Diagnostic accuracy of the cyst aspirate was 84 % (73 % - 91 %) against histopathology at 2-year follow-up (n = 79), and 77 % (70 % - 83 %) against consensus diagnosis among nonsurgical cases (n = 171). Related serious adverse events occurred in 1.2 % (0.2 % - 3.5 %) of patients. CONCLUSIONS Our study results demonstrate a statistically significant difference among the three needles in the overall success rate for aspiration, but not in the percentage of cyst volume aspirated. Flexible needles may be particularly valuable in sampling cystic PCLs in the pancreatic head/uncinate process.

Abstract
Chronic pancreatitis (CP) is an inflammatory process characterized by irreversible morphological changes in the pancreas. Pain is the predominant symptom observed during the course of CP. The etiopathogenesis of pain in CP is multifactorial and includes ductal hypertension due to obstruction of the pancreatic duct (PD), neuropathic causes, and extrapancreatic complications of CP like pseudocyst and distal biliary obstruction. A sizeable proportion of patients with CP are amenable to endoscopic treatment. The mainstay of endotherapy includes decompression of PD with one or more plastic stents in those with stricture, and fragmentation of PD calculi using extracorporeal shock wave lithotripsy. Nearly two-thirds of the patients achieve pain relief in the long term with endotherapy. Upfront assessment for the suitability of endotherapy is paramount to achieve the best outcomes. The predictors of poor response to endotherapy include multifocal disease, like those with multifocal strictures or multiple calculi throughout the pancreas, or a combination of both PD strictures and stones. With the emerging use of covered metal stents, the outcomes are likely to improve in cases with refractory PD strictures as well as CP-related distal biliary obstruction. The optimum stent design and indwell time of metal stents in cases with refractory PD strictures need further evaluation. Endoscopic ultrasonography has emerged as a complementary endoscopic modality in the management of CP as well as associated complications like pseudocysts, refractory pain, and vascular complications.

Abstract
Background and Objectives: EUS-guided biliary drainage (EUS-BD) offers minimally invasive decompression when conventional endoscopic retrograde cholangiopancreatography fails. Stents can be placed from the intrahepatic ducts into the stomach (hepaticogastrostomy [HG]) or from the extrahepatic bile duct into the small intestine (choledochoduodenostomy [CCD]). Long-term patency of these stents is unknown. In this study, we aim to compare long-term patency of CCD versus HG. Methods: Consecutive patients from 12 centers were included in a registry over 14 years. Demographics, procedure info, adverse events, and follow-up data were collected. Student's t-test, Chi–square, and logistic regression analyses were conducted. Only patients with at least 6-month follow-up or who died within 6-month postprocedure were included. Results: One-hundred and eighty-two patients were included (93% male; mean age: 70; HG n = 95, CCD n = 87). No significant difference in indication, diagnosis, dissection instrument, or stent type was seen between the two groups. Technical success was 92% in both groups. Clinical success was achieved in 75/87 (86%) in the HG group and 80/80 (100%) in the CCD group. A trend toward higher adverse events was seen in the CCD group. A total of 25 patients out of 87 needed stent revision in the HG group (success rate 71%), while eight out of 80 were revised in the CCD group (success rate 90%). Chi square shows CCD success higher than HG (90% vs. 71%, P = 0.010). After adjusting for diagnosis, jaundice or cholangitis presentation, instrument used for dissection, and gender, CCD was 4.5 times more likely than HG to achieve longer stent patency or manage obstruction (odds ratio 4.5; 95% 1.1548–17.6500, P = 0.0302). Conclusion: CCD is associated with superior long-term patency than HG but with a trend toward higher adverse events. This is particularly important in patients with increased survival. Additional studies are required before recommending a change in practice.

Abstract
AbstractAbdominal tuberculosis has insidious course and is a diagnostic challenge. Tubercular lymphadenitis is associated with constitutional symptoms and multiple enlarged lymph nodes. Isolated giant lymph nodes are rare in tuberculosis and are common in lymphoma or malignancy. Peripancreatic mass on endosonography are commonly lymph node less than 4 cm. Isolated giant nonnecrotizing lymph node can mimic liver architecture on endoscopic ultrasound but lack a biliary connection.

Abstract
BACKGROUND AND AIM Hemosuccus pancreaticus is considered as one of the rare cause of upper gastrointestinal bleeding. Intermittent nature of bleeding and lack of standardized approach for diagnosis has resulted in significant delay in definitive management. METHODS We retrospectively analyzed prospectively maintained data of patients with suspected hemosuccus pancreaticus between January 2010 and December 2019. RESULTS Out of 114 patients, 87 patients were diagnosed with hemosuccus pancreaticus. Mean age was 35.7 ± 11.7 years with 89.7% men. Median duration of bleeding before diagnosis was 10 days, with 40.2%, 10.3%, and 5.7% patients had symptoms beyond 1, 6, and 12 months, respectively. Visceral artery aneurysm was noted in 62% of cases with splenic artery aneurysm (37.9%) being the common source of bleed. Rarer causes noted were superior mesenteric artery aneurysm, pancreatic adenocarcinoma, gastrointestinal stromal tumor, and post-endoscopic retrograde cholangiopancreatography (2.3% each). Santorinirrhage was seen in 3.4% patients. Endoscopic diagnosis was possible in 64.4% of patients, and angiogram localization of bleeding source was noted in 94.2%. A 56.3% of patients underwent conventional angioembolization with 95.9% success and 28.7% underwent surgery, with overall rebleeding rate of 11.5%. CONCLUSIONS Early diagnosis of hemosuccus pancreaticus avoids prolonged suffering, multiple hospital admissions, and multiple blood transfusions. It is not uncommon in the absence of aneurysm. In cases of high suspicion, repeating the endoscopy with proper technique and proper timing increases the yield. Angioembolization remains the most preferred first line therapeutic approach in majority of cases.

Abstract
Objective Colorectal cancer (CRC) is an emerging public health problem in Asia and India. However, there is scarcity of data on CRC and adenoma. We aimed to study prevalence and characteristics of colonic polyps in a large retrospective cohort.
Methods For this retrospective single center study, all patients with age > 18 years undergoing colonoscopy from January 2018 to December 2019 were included. Age, gender, and polyp characteristics were collected from endoscopy and histology database. Patients with incomplete histology reports and anal canal polyps were excluded. Based on histology, polyps were divided into adenocarcinoma, adenoma with advanced pathology (AAP; size > 10 mm, villous morphology or high-grade dysplasia), nonadvanced adenomas (nAAP), and nonadenomas.
Results Overall colon polyp prevalence was 10.18% (3551/34893). The mean age (standard deviation [SD]) was 51.51 (14.84) with 75.4% males, of which 128 (3.6%) were adenocarcinoma. A total of 1514 (42.64%) were adenomas; 344 (9.7%) were AAP and 1170 (32.9%) were nAAP. The remaining 1909 (53.8%) were nonadenomas. Colonic adenoma prevalence after excluding adenocarcinoma was 4.35% (1514/34893). Adenocarcinoma (68.8% vs. 31.2%), AAP (70.6% vs. 29.4%), other adenomas (75.4% vs. 24.6%), and nonadenomas (76.7% vs. 23.3%) were significantly higher in male compared with female (p < 0.05). Adenomas and adenocarcinomas were more common in left colon and rectum than right colon (p < 0.05). The mean age (SD) were significantly lower in nonadenomas than adenocarcinomas, AAP, and other adenomas (p 0.0001; 49.25 [14.84] vs. 55.97 [12.47], 54.78 [16.40], 53.76 [13.71]).
Conclusions The prevalence of colonic adenoma in India is 4.35%. Male gender and increased age were associated with increased risk of colonic adenoma and adenocarcinoma, which is more common in left colon and rectum. Prospective multicenter studies are required for evaluation of other risk factors of CRC and colonic adenomas.

Abstract
BACKGROUND & AIMS Benign biliary strictures (BBS) are complications of chronic pancreatitis (CP). Endotherapy using multiple plastic stents (MPS) or a fully covered self-expanding metal stent (FCSEMS) are acceptable treatment options for biliary obstructive symptoms in these patients. METHODS Patients with symptomatic CP-associated BBS enrolled in a multicenter randomized noninferiority trial comparing 12-month treatment with MPS vs FCSEMS. Primary outcome was stricture resolution status at 24 months, defined as absence of restenting and 24-month serum alkaline phosphatase not exceeding twice the level at stenting completion. Secondary outcomes included crossover rate, numbers of endoscopic retrograde cholangiopancreatography (ERCPs) and stents, and stent- or procedure-related serious adverse events. RESULTS Eighty-four patients were randomized to MPS and 80 to FCSEMS. Baseline technical success was 97.6% for MPS and 98.6% for FCSEMS. Eleven patients crossed over from MPS to FCSEMS, and 10 from FCSEMS to MPS. For MPS vs FCSEMS, respectively, stricture resolution status at 24 months was 77.1% (54/70) vs 75.8% (47/62) (P = .008 for noninferiority intention-to-treat analysis), mean number of ERCPs was 3.9 ± 1.3 vs 2.6 ± 1.3 (P < .001, intention-to-treat), and mean number of stents placed was 7.0 ± 4.4 vs 1.3 ± .6 (P < .001, as-treated). Serious adverse events occurred in 16 (19.0%) MPS and 19 (23.8%) FCSEMS patients (P = .568), including cholangitis/fever/jaundice (9 vs 7 patients respectively), abdominal pain (5 vs 5), cholecystitis (1 vs 3) and post-ERCP pancreatitis (0 vs 2). No stent- or procedure-related deaths occurred. CONCLUSIONS Endotherapy of CP-associated BBS has similar efficacy and safety for 12-month treatment using MPS compared with a single FCSEMS, with FCSEMS requiring fewer ERCPs over 2 years.

Abstract
BACKGROUND Although endoscopic ultrasound (EUS) features and criteria have been described in chronic pancreatitis, challenges remain with interoperator variability and ease of adoption. The aim of this study was to define and validate the EUS features of chronic pancreatitis in a multicenter prospective study in Asia. METHOD The study was divided into two parts: the first part was conducted to derive the EUS features of chronic pancreatitis with adequate interoperator agreement; the second was to prospectively evaluate these features in a multicenter cross-sectional study and determine the optimal combination of features for the diagnosis of chronic pancreatitis. Prospectively enrolled cases had standard internationally validated radiologic or histologic features of chronic pancreatitis, and controls were patients without chronic pancreatitis who underwent EUS examination. RESULTS The top six EUS features that had good interobserver agreement (mean kappa 0.73, range 0.60 - 0.90) were selected to be further evaluated in part II of the study. These included: hyperechoic foci with shadowing, lobularity with honeycombing, cysts, dilated main pancreatic duct, dilated side branches, and calculi in the main pancreatic duct. A total of 284 subjects (132 cases, 152 controls) were enrolled from 12 centers in Asia. All six features had high accuracy ranging from 63.3 % to 89.1 %. Two or more of these six EUS features accurately defined chronic pancreatitis (sensitivity 94.7 %, specificity 98.0 %), with an area under the receiver operating curve of 0.986. CONCLUSION This multicenter Asian study characterized and defined the EUS features of chronic pancreatitis. This provides a useful tool in clinical practice and further research in pancreatic cancer surveillance.

Abstract
BACKGROUND AND AIM Even though ductal interventions in chronic pancreatitis (CP) are known to improve pain, its impact on diabetes is unclear. In this cohort study, we evaluated the impact of ductal interventions on diabetes in these patients. METHODS Consecutive patients with CP visiting the pancreas clinic between August 1, 2011, and July 21, 2012, were enrolled and followed until December 2018. Detailed clinical, laboratory, imaging, and treatment data were recorded at enrolment and follow-up. Patients were followed up every 6 months through hospital visit and/or telephonic interview. Risk factors for diabetes were evaluated using logistic regression. The impact of ductal interventions on diabetes was evaluated using Kaplan-Meier survival analyses and Cox proportional hazards. RESULTS A total of 644 patients were enrolled of which 137 were excluded. Of these, 326 (64.3%) patients had idiopathic CP, and 283 (55.8%) patients underwent ductal intervention. The cumulative incidence of diabetes was 57.9%. Median duration between symptom onset and ductal intervention was similar irrespective of diabetes (2.6 [0.6-6.0] vs 3.0 [1.0-5.5] years; P = 0.69). Alcohol intake and pancreatic ductal calculi were independent risk factors for diabetes (odds ratio [95% confidence interval] of 2.05 (1.18-3.55), P = 0.01, and 2.05 (1.28-3.28), P = 0.003, respectively). Kaplan-Meier analyses revealed that diabetes free interval was significantly longer in patients undergoing ductal interventions, predominantly in those with idiopathic CP with obstructive ductal calculi (hazard ratio [95% confidence interval] 0.39 [0.28-0.55]; P < 0.0001). There were no differences in glycemic status in patients with non-idiopathic CP and those with pre-existing diabetes. CONCLUSION Early ductal intervention could delay development of diabetes in patients with idiopathic CP with obstructive ductal calculi.

Abstract
Abstract
Background Recently updated guidelines for choledocholithiasis stratify suspected patients into high, intermediate, and low likelihood, with the aim to reduce risk of diagnostic endoscopic retrograde cholangiopancreatography. This approach has increased proportion of patients in intermediate likelihood making it heterogenous. We aim to substratify intermediate group so that diagnostic tests (endoscopic ultrasound/magnetic resonance cholangiopancreatography) are judicially used.
Methods This is a single-center retrospective analysis of prospectively maintained data. We used subset of patients who met intermediate likelihood of American Society of Gastrointestinal Endoscopy (ASGE) criteria from previously published data (PMID:32106321) as derivation cohort. Binominal logistic regression analysis was used to define independent predictors of choledocholithiasis. A composite score was derived by allotting 1 point for presence of each independent predictor. The diagnostic performance of a composite score of ≥ 1 was evaluated in validation cohort.
Results A total of 678 (mean age [standard deviation]: 47.0 [15.9] years; 48.1% men) and 162 (mean age 47.8 [14.8] years; 47.4% men) patients in ASGE intermediate-likelihood group were included as derivation cohort and validation cohort, respectively. Binominal logistic regression analysis showed that male gender (p = 0.024; odds ratio [OR] = 1.92), raised bilirubin (p = 0.001; OR = 2.40), and acute calculus cholecystitis (p = 0.010; OR = 2.04) were independent predictors for choledocholithiasis. A composite score was derived by allotting 1 point for presence of independent predictors Using ≥ 1 as cutoff, sensitivity and specificity for detection of choledocholithiasis were 80% (95% confidence interval [CI]: 68.2–88.9) and 36.2% (95% CI: 32.2–40.0), respectively, in derivation cohort. Applying composite score in independent validation cohort showed sensitivity and specificity of 73.3% (95% CI: 44.9–92.2) and 40.1% (95% CI: 30.1–48.5), respectively.
Conclusion Substratification of intermediate-likelihood group of ASGE criteria is feasible. It may be useful in deciding in whom confirmatory tests should be performed with priority and in whom watchful waiting may be sufficient.

Abstract
Background Acute calculous cholecystitis (ACC) is the most frequent complication of gallstones requiring cholecystectomy. These patients may have coexisting choledocholithiasis. We aimed to evaluate the role of current guidelines for choledocholithiasis in patients with ACC. Methods In this retrospective study, we included all patients diagnosed with ACC between December 2018 and May 2019. These patients were substratified according to the guidelines of the American and European Societies of Gastrointestinal Endoscopy (ASGE and ESGE) as having high, intermediate, or low likelihood of choledocholithiasis, and the diagnostic performance was measured. Binomial logistic regression analysis was applied to ascertain independent risk factors for choledocholithiasis. Results A total of 173 patients with ACC, mean age (±standard deviation) 49.89±15.74 years and 60.1% male, were included. Sixty-three (36.4%) had confirmed choledocholithiasis. ASGE high likelihood criteria had sensitivity and specificity of 61.9% (95% confidence interval [CI] 48.8-73.9) and 83.4% (95%CI 75.4-90.0) for predicting choledocholithiasis. ESGE high likelihood criteria had sensitivity and specificity of 49.2% (95%CI 36.4-62.1) and 87.3% (95%CI 79.6-92.9). On logistic regression analysis, an alkaline phosphatase level above the upper limit of normal (P=0.003; odds ratio [OR] 4.26, 95%CI 1.66-10.96) and a dilated common bile duct on ultrasound (P=0.001; OR 9.97, 95%CI 4.65-21.36) were independent positive predictors for choledocholithiasis, while acute biliary pancreatitis was an independent negative predictor (P=0.030; OR 0.36, 95%CI 0.14-0.91). Conclusions The performance of the ASGE and ESGE guidelines’ risk stratification criteria is inadequate in patients with ACC. We suggest the utilization of a separate predictive model for suspected choledocholithiasis in these patients.

Abstract
Background To compare fully covered bi-flanged metal stents (BFMS) and lumen-apposing metal stents (LAMS) for endoscopic ultrasound (EUS)-guided drainage/debridement of pancreatic walled-off necrosis (WON). Methods Patients with WON managed by EUS-guided therapy were divided into those who underwent: 1) drainage using BFMS; and 2) drainage using LAMS and scheduled direct endoscopic necrosectomy (DEN). Clinical success (resolution of the WON), technical success (successful stent placement), and adverse events (AEs) were evaluated. Results 387 patients underwent WON endoscopic drainage, 205 using BFMS and 182 using LAMS. The clinical success in the BFMS or LAMS groups were similar (197 [96.1%] vs. 174 [95.6%]; P=0.81). Median number of procedures required for WON resolution was significantly lower in BFMS compared to LAMS (2 vs. 3, P<0.001). Technical success for stent placement was similar in BFMS and LAMS groups (203 [99%] vs. 180 [99%], P=0.90). Procedure-related AEs were similar in the BFMS and LAMS groups (19 [9.3%] vs. 20 [10.9%], P=0.61). Stent dysfunction with occluding debris was higher in the BFMS group compared to LAMS group (21 [10.2 %] vs. 11 [5.9%], P=0.04). The migration rate was higher in the BFMS group than in the LAMS group (15 [7.3%] vs. 3 [1.6%]; P<0.001). DEN was required in 23 [11.2%] patients in the BFMS group after lack of WON resolution by conservative means. Conclusion BFMS with a “step-up approach” and LAMS with scheduled DEN are both safe and effective for EUS-guided drainage/debridement of WON.
