Success of Intraoperative Cholangiography

Study Overview
=================
Brief Summary
-----------------
The purpose of the present study was to evaluate the success of routine use of intraoperative cholangiography (IOC ) and to examine the factors that are hindering the performance of intraoperative c-arm cholangiography.

Detailed Description
-----------------
From January 2018 to August 2018 all consecutive elective and emergency cholecystectomies performed were entered in a prospective database. IOC has been instructed to be performed routinely when feasible during cholecystectomy since 1998. All elective operations were performed either by residents or specialist surgeons. For this study the investigators collected the radiation exposure values from exposure and pulsed fluoroscopy. Fluoroscopy time (s) was recorded.The operating surgeon was asked to fulfill a questionnaire directly after the cholecystectomy. The technical success and reasons for possible deferral of IOC were documented.Patient data from unsuccessful or deferred cholangiography cases was checked 6 months after cholecystectomy for possible symptomatic residual choledocholithiasis.Laparoscopic cholecystectomies were performed both by residents and specialist surgeons. Ethics: The study was approved by the hospital administration.
