Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This retrospective observational study will include all patients with CBD stones who underwent CBD exploration for stone using Ambu aScope in Department of Surgery of BPKIHS, Dharan between January 2022 and December 2024.
Case record files of all patients who underwent CBD exploration using aScope as a Choledochoscope over last 3 years period will be obtained from medical record section and computer database of our department. All relevant information including patient demographics, indication for a CBD exploration, operative approach and procedure performed, intraoperative achievement of acceptable view of extrahepatic biliary tree using an aScope, intraoperative stone clearance on direct visualization of biliary tree and confirmation on postoperative T-tube cholangiogram or imaging on 10-14th postoperative day and intra/post-operative complications associated with the use of the aScope will be entered in a preformed proforma. In case of some missing information in medical case report sheet or computer database of our department, patient will be called directly on the contact number provided in admission sheet and through the telephonic conversation, the concerned queries will be cleared. Data will be entered in Microsoft Excel and analyzed by SPSS version 29.0.1.0. Qualitative data were described using numbers and percentages. Quantitative data will be described using range (minimum and maximum), mean, standard deviation, and median.
