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

Background: Previous data from South Asia and India had shown that patients with nonalcoholic fatty liver disease (NAFLD) have mild liver disease severity. There are no data regarding long-term clinical outcomes in patients with NAFLD from South Asia. The aim of the study was to evaluate the clinicopathological profile, severity of NAFLD, and clinical outcomes in a large cohort of patients with NAFLD from South Asia. Methods: In an ongoing real-life study [Indian Consortium on nonalcoholic fatty liver disease (ICON-D)], interim data captured across 23 centers in India over 18 months was analyzed for clinicopathological profile, severity of NAFLD, and hepatic/extrahepatic events on follow-up. Results: Of 4313 patients (mean age 45 ± 12.2 years, males 52%), data on metabolic risk factors in 3553 (82.3%) patients revealed that 378 (10.6%) were lean, 575 (16.2%) overweight, 2584 (72.7%) obese; metabolic syndrome in 1518 (42.7%) and at least one metabolic risk factor in 3292 (92.6%) patients. Evidence of significant or advanced fibrosis assessed with [aspartate transaminase to platelet ratio index (APRI), n = 3196 (74%)], [fibrosis-4 (FIB-4), n = 3554 (82.4%)], [NAFLD fibrosis score (NFS), n = 1924 (44.6%)], [Fibroscan, n = 2475, (57.3%)], and histology [n = 267 (6.2%)] was present in 682 (21.3%), 676 (19%), 397 (20.6%), 715 (29%), and 41 (15.4%) patients, respectively; 246 (10%) patients on Fibroscan and 22 (8.2%) on histology had evidence of cirrhosis. On a mean follow-up 43.5 months, hepatic and extrahepatic events recorded in 1353 (31.3%) patients showed that patients with compensated cirrhosis [71 (5.2%)] had more hepatic [26 (36.7%)] and extrahepatic events [8 (11.3%)] in comparison with those without cirrhosis (P < 0.0001). Conclusion: Around one fifth of patients with NAFLD in South Asia have significant liver disease. Both hepatic and extrahepatic events on follow-up are observed more commonly in patients with nonalcoholic steatohepatitis-related compensated cirrhosis.

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.

Geriatric patients tend to have subtle presentations of biliary disorders and, if untreated, can decompensate acutely. Each biliary disorder warrants formulation of an individualized treatment plan with a multidisciplinary approach. Acute cholecystitis, a common complication of gallstones, is initially managed by conservative measures and subsequently, among patients with optimal surgical risk, through laparoscopic or open cholecystectomy. High-risk patients undergo temporization, percutaneous or endoscopic, followed by definitive intervention. Acute cholecystitis with complications (ie, perforation, gangrene, or small bowel obstruction) warrants emergent cholecystectomy. Gallstone migration into the biliary system can cause choledocholithiasis, often complicated by biliary pancreatitis or cholangitis if not intervened. Therapy for choledocholithiasis is based on biliary clearance through endoscopic and, infrequently, surgical approaches.

Background and study aims The Full-Thickness Resection Device (FTRD) provides a novel treatment option for lesions not amenable to conventional endoscopic resection techniques. There are limited data on the efficacy and safety of FTRD for resection of upper gastrointestinal tract (GIT) lesions. Patients and methods This was an international multicenter retrospective study, including patients who had an endoscopic resection of an upper GIT lesion using the FTRD between January 2017 and February 2019. Results Fifty-six patients from 13 centers were included. The most common lesions were mesenchymal neoplasms (nâ=â23, 41â%), adenomas (nâ=â7, 13â%), and hamartomas (nâ=â6, 11â%). Eighty-four percent of lesions were located in the stomach, and 14â% in the duodenum. The average size of lesions was 14âmm (range 3 to 33âmm). Deployment of the FTRD was technically successful in 93â% of patients (nâ=â52) leading to complete and partial resection in 43 (77â%) and 9 (16â%) patients, respectively. Overall, the FTRD led to negative histological margins (R0 resection) in 38 (68â%) of patients. A total of 12 (21â%) mild or moderate adverse events (AEs) were reported. Follow-up endoscopy was performed in 31 patients (55â%), on average 88 days after the procedure (IQR 68-138 days). Of these, 30 patients (97â%) did not have any residual or recurrent lesion on endoscopic examination and biopsy, with residual adenoma in one patient (3â%). Conclusions Our results suggest a high technical success rate and an acceptable histologically complete resection rate, with a low risk of AEs and early recurrence for FTRD resection of upper GIT lesions.
RESUMEN
Direct endoscopic imaging of the biliary tree is increasingly performed by endoscopists since the introduction of digital single-operator cholangioscopy. In parallel, there have been several advances to overcome the challenges associated with direct peroral cholangioscopy with development of multibending cholangioscopes and new devices to enable direct placement of an endoscope into the biliary tree without a supporting duodenoscope. The indications for cholangioscopy are also evolving with newer indications, such as intraductal lithotripsy, foreign body (mostly stent) removal, guide wire cannulation of specific ducts, photodynamic therapy for cholangiocarcinoma, and performance of fluoroscopy-free cholangiography. There has also been progress in image enhancement during cholangioscopy and additional imaging techniques, such as intraductal ultrasound, confocal laser endomicroscopy, and optical coherence tomography.

OBJECTIVE: To report the changing incidence, clinical presentation, microbiologic spectrum, and outcomes of pyogenic liver abscess (PLA) in Olmsted County, Minnesota, over the past 35 years. PATIENTS AND METHODS: The Rochester Epidemiology Project was used to identify residents with PLA from January 1, 1980, through December 31, 2014. The study included all patients older than 18 years, with the diagnosis of PLA confirmed through radiographic review and microbiologic cultures. RESULTS: In total, 72 patients received a diagnosis of PLA from 1980 through 2014. The age-adjusted incidence for men was 3.92 cases per 100,000 person-years (95% CI, 2.76-5.09 cases per 100,000 person-years) compared with 1.87 cases per 100,000 person-years (95% CI, 1.15-2.59 cases per 100,000 person-years) for women. Incidence was higher in the period from January 1, 2001, through December 31, 2014, than in the period from January 1, 1980, through December 31, 2000, for women (incidence rate ratio [IRR], 3.8; 95% CI, 1.43-10.09; P=.007) but not for men (IRR, 0.99; 95% CI, 0.55-1.76; P=.96). Fifteen additional patients had postintervention PLA (1980-2000: n=3 of 29 [10.3%] vs 2001-2015: n=12 of 58 [20.6%]). A significant association was seen between age- and sex-adjusted incidence rates of PLA and year of diagnosis (per year since 1980: IRR, 1.04; 95% CI, 1.02-1.07; P<.001) after including postintervention PLA. Streptococcus milleri was the most common organism identified (52.5%). Organisms with multidrug resistance were more common in the period from 2001 through 2014 than in the period from 1980 through 2000 (51% vs 14%; P=.005). The overall mortality rate of PLA was 16.8% (95% CI, 7.6%-25.0%) at 6 months. CONCLUSION: The incidence of PLA is increasing, probably because of increase in frequency of hepatobiliary interventions and organisms with multidrug resistance.
RESUMEN
BACKGROUND & AIMS: A diagnosis of pancreatic cancer in a first-degree relative increases an individuals' risk of this cancer. However, it is not clear whether this cancer risk increases in individuals with pancreatic cystic lesions who have a first-degree relative with pancreatic cancer. The Fukuoka criteria are used to estimate risk of pancreatic cancer for patients with pancreatic cystic lesions: individuals with cysts with high risk or worrisome features (Fukuoka positive) have a higher risk of pancreatic cancer than individuals without these features (Fukuoka negative). We aimed to compare the risk of pancreatic cancer and surgery based on presence or absence of pancreatic cystic lesions and a first-degree relative with pancreatic cancer. METHODS: We performed a retrospective study of patients seen at the Mayo Clinic in Rochester, Minnesota, from January 1, 2000, through December 31, 2012. We identified individuals with: pancreatic cystic lesions and first-degree relative with pancreatic cancer (group 1, n = 269), individuals with pancreatic cystic lesions but no first-degree relative with pancreatic cancer (group 2, n = 1195), and individuals without pancreatic cystic lesions but with a first-degree relative with pancreatic cancer (group 3, n = 720). We compared, among groups, as well among patients with cysts classified according to Fukuoka criteria, proportions of individuals who developed pancreatic cancer or underwent pancreatic surgery within a 5-year period. RESULTS: A significantly higher proportion of individuals in group 1 developed pancreatic cancer during the 5-year period than in group 3 (6.64% vs 1.69%; P = .03); there was no significant difference between the percentage of individuals in group 1 vs group 2 who developed pancreatic cancer (6.64% vs 4.05%; P = .41). There was no significant difference in pancreatic cancer development among individuals with Fukuoka-positive cysts with vs without a family history of pancreatic cancer (P = .39). There was no significant difference in the proportion of patients in group 1 vs group 2 who underwent pancreatic surgery for their pancreatic cyst over the 5-year period (14.37% vs 11.80%; P = .59). Among patients with Fukuoka-negative cysts, a significantly higher proportion underwent surgery in group 1 than in group 2 (10.90% vs 5.90%; P = .03). However, among patients with Fukuoka-positive cysts, there was no difference in proportions of patients who underwent surgery between groups 1 and 2 (P = .66). CONCLUSIONS: In a retrospective study of patients with pancreatic cysts and/or cancer, we found that a family history of pancreatic cancer does not affect 5-year risk of pancreatic cancer in patients with pancreatic cystic lesions. Despite this, among patients with Fukuoka-negative cysts, a higher proportion of those with a family history of pancreatic cancer undergo surgery than patients without family history of pancreatic cancer.

BACKGROUND AND AIMS: Symptomatic pancreatic walled-off necrosis (WON) may be managed by endoscopic transmural drainage and endoscopic transmural necrosectomy, with stent placement at endoscopic drainage sites. The optimal stent choice is yet to be determined. We compared outcomes after endoscopic management of WON using either large-caliber fully covered self-expandable metal stents (LC-SEMSs) or double-pigtail plastic stents (DPPSs). METHODS: We performed a retrospective comparison of outcomes among patients who received LC-SEMSs or DPPSs before endoscopic transmural necrosectomy for WON. RESULTS: Among 94 patients included, WON resolution rates did not differ between the DPPS (36 patients) and LC-SEMS (58 patients) groups, whether concomitant percutaneous drainage was considered a failure (75% vs 82.8%; P = .36) or not (91.7% vs 94.8%; P = .55). Of 75 patients (80%) successfully treated without percutaneous drainage, 37 (49%) underwent endoscopic transmural drainage without subsequent endoscopic transmural necrosectomy. WON was more likely to resolve without subsequent endoscopic transmural necrosectomy in the LC-SEMS group than the DPPS group (60.4% vs 30.8%; P = .01). WON resolution without subsequent endoscopic transmural necrosectomy remained more likely with LC-SEMSs (odds ratio, 4.5 [95% confidence interval, 1.5-15.5]) after adjusting for patient age and size and location of WON. Rates of adverse events were similar except for clinically significant bleeding requiring endoscopic intervention, which was higher with DPPSs than LC-SEMSs (14% vs 2%; P = .02). CONCLUSION: Management of pancreatic WON with LC-SEMSs appears to decrease both the need for repeated necrosectomy procedures and the risk of intervention-related hemorrhage.

BACKGROUND AND AIMS: Gastric ischemia is a rare condition associated with poor prognosis. Our study aim was to highlight the clinical features and outcomes of patients with gastric ischemia. METHODS: A retrospective review of patients diagnosed with isolated gastric ischemia at our institution from January 1, 2000, to May 5, 2016, was performed. Demographic, clinical, endoscopic, radiologic, and outcome variables were abstracted for analysis. RESULTS: Seventeen patients (65% men) with mean age of 69.3 ± 11.3 years and body mass index of 28.8 ± 11.1 were identified. The etiologies for gastric ischemia included local vascular causes (n = 8), systemic hypoperfusion (n = 4), and mechanical obstruction (n = 5). The most common presenting symptoms were abdominal pain (65%), gastrointestinal bleeding (47%), and altered mental status (23%). The typical endoscopic appearance was mucosal congestion and erythema with or without ulceration. Gastric pneumatosis and portal venous air were more commonly seen on CT imaging. Radiologic and/or surgical intervention was needed in 9 patients, while the remaining 8 patients were managed conservatively with acid suppression, antibiotics, and nasogastric tube decompression. The median duration of hospital stay was 15 days (range 1-36 days). There were no cases of rebleeding and the mortality rate as a direct result of gastric ischemia was 24% within 6 months of diagnosis. CONCLUSION: Although uncommon, gastric ischemia is associated with significant mortality. Endoscopy and CT imaging play an important role in its diagnosis. The management of gastric ischemia is dictated by its severity and associated comorbidities.
