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.

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.

Inclusion Criteria:

• all consecutive cholecystectomy patients during January 2018 to August 2018

Exclusion Criteria:

• none

all consecutive cholecystectomy patients during January 2018 to August 2018 which are operated with open or laparoscopic cholecystectomy for symptomatic cholelithiasis
