Prospective Validation of "Cholecystectomy First" Strategy for Gallstone Migration
Initial Cholecystectomy With Intraoperative Cholangiography for Patients at Intermediate Risk of Common Bile Duct Stone Migration : Prospective Validation and Analysis
연구 개요
상태
상세 설명
A previous randomized controlled trial comparing initial cholecystectomy with intraoperative cholangiogram (IOC) versus common bile duct (CBD) assessment and subsequent cholecystectomy for patients admitted in the emergency room with an acute gallstone-related condition and with an intermediate risk of common bile duct stone was performed by the investigators. This study had been registered on Clinicaltrials.gov as well and had shown that a strategy with initial cholecystectomy significantly decreased the length of hospital stay and the number of CBD investigations procedures.
Initial cholecystectomy with IOC is now the standard management strategy for these patients in the investigators hospital. The goal of this study is to perform a prospective validation of this strategy and to analyze if the results obtained in the previously mentioned randomized controlled trial are confirmed on a larger patients cohort. This study will be observational, since the intervention (initial cholecystectomy) is not assigned by the investigators, but is already a standard treatment strategy at our institution.

Validation cohort
All patients of the study (single group, single arm) will undergo initial cholecystectomy with intraoperative cholangiogram, followed if required by ERCP, according to the standard protocol of treatment previously implemented at the investigators institution.

cf. arm/group description.
This intervention is not assigned by the investigators: it is the standard treatment at the investigators institution.
