This article, published in the journal Endoscopy, explores the predictive factors for failed cannulation of the common bile duct (CBD) during endoscopic treatment of biliary lithiasis. The study, conducted retrospectively from June 2017 to September 2022, included 498 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) for CBD stones. The researchers found that papilla characteristics, such as small size, hidden location, and difficult orientation, were the main factors influencing the success rate of CBD cannulation. Additionally, the use of advanced catheterization techniques was also identified as a predictive factor for failed cannulation. The authors suggest that larger-scale studies are needed to further investigate these factors and develop effective management strategies for ERCP. [Extracted from the article]

This article, published in the journal Endoscopy, examines the factors associated with the failure of clearing common bile stones during endoscopic retrograde cholangiopancreatography (ERCP). The study analyzed 498 patients who underwent ERCP for stone extraction and found that failed stone removal was more likely in patients with multiple common bile duct stones and a diameter of 15mm or greater. Other factors associated with failure included age over 65, acute cholangitis, fever, elevated total bilirubin, leukocytosis, infected bile, large stones, a ratio of stone size to CBD diameter greater than 1, and impacted stones. The use of a balloon catheter was associated with successful clearance. [Extracted from the article]

This article discusses the results of a study conducted at a Tunisian hospital on the use of preoperative endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of common bile duct (CBD) stones associated with gallstones. The study included 498 patients, with a mean age of 61.08 years. The success rate of bile duct cannulation during the first ERCP was 93.7%, and for those with failed cannulation, a second ERCP was successful in all cases. Bile duct clearance was achieved in 90.03% of cases after the first ERCP, and in 92.83% of cases overall. Complications were observed in a small percentage of patients, including bleeding during the procedure and post-procedure complications such as acute pancreatitis and cholangitis. The study concludes that preoperative ERCP is an efficient and safe treatment for the management of CBD stones associated with gallstones. [Extracted from the article]

This article, published in the journal Endoscopy, examines the prevalence and predictors of unnecessary endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of common bile duct stones (CBDS). The study conducted a retrospective analysis of 475 patients who underwent ERCP for CBDS over a 5-year period. The results showed that ERCP was unnecessary in approximately one-third of the patients, with factors such as age, stone size, stone type, and the time interval between imaging and ERCP being identified as predictors of unnecessary ERCP. The study highlights the importance of careful evaluation and consideration of these factors in order to avoid unnecessary procedures. [Extracted from the article]
