Event Description

Olympus reviewed the following literature titled, "balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography for the treatment of common bile duct stones in patients with roux-en-y gastrectomy: outcomes and factors affecting complete stone extraction." this retrospective study investigated the treatment outcomes and potential factors affecting complete stone extraction in 79 patients.The initial success rates of reaching the papilla of vater, biliary cannulation, and biliary intervention, including complete stone extraction or biliary stent placement, were 92%, 81%, and 78%, respectively.The multivariate analysis indicated that the largest cbd diameter = 14 mm (odds ratio (or), 0.04; 95% confidence interval (ci), 0.01¿0.58) and retroflex position (or, 6.43; 95% ci, 1.12¿36.81) were independent predictive factors affecting complete stone extraction achievement.This study concludes that therapeutic sdbe-ercp for cbd stones in a relatively elderly ryg cohort, was effective and safe.Type of adverse events/number of patients, mild perforation - 1 patient, moderate perforation - 1 patient, mild pancreatitis - 1 patient, mild hypoxia - 1 patient.This was a multi-center retrospective study conducted in three tertiary hospitals.This literature article requires 8 reports.The related patient identifiers are as follows: (b)(6)/pr-v220q/ae, (b)(6)/kd-10q-1/ae, (b)(6)/fg-v425pr/ae, (b)(6)/bml-v437qr-30/ae, (b)(6)/pr-v220q/hypoxia for 83-year-old, (b)(6)/kd-10q-1/hypoxia for 83-year-old, (b)(6)/fg-v425pr/hypoxia for 83-year-old, (b)(6)/bml-v437qr-30/hypoxia for 83-year-old., this medwatch is for patient identifier (b)(6).There is no report of any olympus device malfunction in any procedure described in this study.
