Background: Pancreaticobiliary diseases and choledocholithiasis are common in elderly patients. Endoscopic treatment of biliary stones represents a well-established mini-invasive technique. However, limited data are available regarding the treatment of 'difficult' biliary stones, especially in the elderly population. The aim of our study is to evaluate the efficacy and safety of therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in patients ≥85 years of age with complex biliary stones.Materials and Methods: From January 2015 to January 2017, data from ERCP procedures performed for complex biliary stones were retrospectively collected. The patients were divided into two groups based on their age: Group A - aged 85 years or older (n = 110) and Group B - aged 65 years or younger (n = 62). Demographic data, success, complications and recurrence rates for both groups were reported.Results: Chronic comorbidities (86.3% vs. 24.2%; P < 0.001) and use of antithrombotic drugs (48.2% vs. 19.3%; P < 0.001) were more frequent in the elderly. The technical success rate (95.4% vs. 96.7%; P > 0.6) and complication rate (8.2% vs. 13%; P > 0.2) were not statistically different among the two groups. Periampullary diverticula (PAD) were observed more frequently in Group A (38.1% vs. 17.7%; P < 0.006). More patients from Group B underwent cholecystectomy during the same admission (8.2% vs. 42.3%; P < 0.001). The recurrence rate was not different among the groups (7.6% vs. 5%; P > 0.5). PAD was identified as the risk factor for recurrence (P < 0.02).Conclusion: ERCP in the elderly was found to be a safe procedure, carrying a high degree of success for the treatment of difficult biliary stones.

Objectives: Clinical evidence regarding radiological–endoscopic management of intrahepatic bile duct stones is currently lacking. Our aim is to report our 18-year experience in combined radiological–endoscopic management of intrahepatic difficult bile duct stones. Methods: From June 1994 to June 2012, 299 symptomatic patients with difficult bile duct stones were admitted to our institution. Percutaneous transhepatic cholangiography (PTC)/biliary drainage/s was performed, dilating the PTC track to 10 or 16 French within 3–7 days. Afterward we carried out percutaneous transhepatic cholangioscopy (PTCS) with electrohydraulic lithotripsy (EHL) and/or interventional radiology techniques. Follow up was made with clinical/laboratory tests and ultrasound (US). We retrospectively analyzed our radiological–endoscopic approach and reported our technical and clinical outcomes. Results: Complete stone clearance was achieved in 298 patients after a maximum of 4 consecutive sessions. Most patients (64.6%) were treated with PTCS/EHL alone, while the remaining with radiological techniques alone (26%) or a combination of both techniques (13.3%). Recurrence of stones occurred in 45 cases (15%, Tsunoda class III and class IV) within 2 years and were successfully retreated. Major adverse events were: 5 (1.6%) cases of massive bleeding that required embolisation, 2 (0.66%) perforations of the common bile duct and 31 cases (10.3%) of acute cholangitis managed with medical therapy or intervention. Conclusion: After 18 years of experience we demonstrated that our combined radiological–endoscopic approach to ‘difficult bile duct stones‘ may result in both immediate and long-term clearance of stones with a low rate of adverse events.

Introduction: Needle-knife sphincterotomy (NKS), known as ‘precut’, is used worldwide to facilitate access to the common bile duct when standard cannulation has failed. This procedure is considered hazardous because it is burdened with high procedural related complications (bleeding and perforation). Its right timing is still debated. In this study we report our results using a modified precut approach, early shallow needle-knife papillotomy (eSNKP) coupled with guidewire cannulation in case of difficult papilla. We evaluated its safety and effectiveness. Methods: From 2012 to 2014, 1034 patients underwent therapeutic ERCP. A total of 138 of them presented difficult papilla and were treated with eSNKP performed after 5 failed attempts of standard guidewire cannulation. Deep biliary cannulation rate was recorded, as well as intraoperative and postoperative complication rate. Results: Successful biliary deep cannulation was achieved in 132/138 patients (95.7%) by means of eSNKP. In 6 patients (4.3%), cannulation failed even after eSNKP. ERCP was newly performed 72 hours later with successful and immediate guidewire biliary cannulation. Overall morbidity was 10.1% (14/138). No perforation occurred. Minor bleeding occurred in 4/138 cases (2.9%) and 10/138 patients (7.2%) developed mild pancreatitis. Conclusion: In case of difficult papilla, eSNKP followed by guidewire cannulation increases the successful deep biliary cannulation with low rate of complications.
