Tokyo, July 18 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000058499) titled 'Comparative study of endoscopic ultrasound-guided treatment and balloon-enteroscopy assisted endoscopic retrograde cholangiopancreatography approach for the treatment of large bile duct stone removal in surgically altered anatomy' on July 17.

Study Type: Observational

Primary Sponsor: Institute - Oita University

Condition: Condition - large bile duct stone in patients with surgical altered anatomy Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - Comparison of complete stone removal rate of endoscopic ultrasound-guided treatment and balloon enteroscopy assisted endoscopic retrograde cholangiopancreatography for large bile duct stone in patients with surgical altered anatomy Basic objectives2 - Safety

Eligibility: Age-lower limit - 18 years-old = Gender - Male and Female Key inclusion criteria - From January 2016 to February 2025, patients and endoscopic procedures for bile duct stones in surgical altered anatomy (SAA) treated with either EUS-T or BE-ERCP. Bile duct stone 12mm or more in diameter Key exclusion criteria - In patients who underwent EUS-T sessions following failed BE-ERCP sessions, or BE-ERCP sessions following failed EUS-T sessions, each EUS-T and BE-ERCP both the failed and subsequent alternative sessions was analyzed and compared separately as an individual session series if there was no change in the size and number of target stones. Cases treated alternately with EUS-T and BE-ERCP repeatedly (e.g., first treatment with EUS-T, second with BE-ERCP, third with EUS-T), those treated using the rendezvous technique, those who underwent on going treatment, cases without adequate datasets were excluded. Target Size - 130

Recruitment Status: Recruitment status - Open public recruiting Date of protocol fixation - 2025 Year 06 Month 27 Day Date of IRB - 2025 Year 06 Month 27 Day Anticipated trial start date - 2025 Year 07 Month 17 Day Last follow-up date - 2029 Year 03 Month 31 Day
