N-OTC is associated with shorter operative time and fewer peri-operative complications , and it is comparable to R-OTC in terms of CBD injury risk during cholecystectomy .
R-OTC is helpful for peri-operative CBD stone detection and there is therefore reduced readmission for retained CBD stones .
The N-OTC approach may be adopted routinely for patients undergoing laparoscopic cholecystectomy providing there are no clinical , biochemical or radiological features suggestive of CBD stones .
INTRODUCTION The aim of this review was to systemically analyse trials evaluating the efficacy of routine on-table cholangiography ( R-OTC ) versus no on-table cholangiography ( N-OTC ) in patients undergoing cholecystectomy .
Does routine intraoperative cholangiography prevent bile duct transection?
Background The role of routine intraoperative cholangiography is controversial . The aim of this study was to assess the impact of routine intraoperative cholangiography on the incidence of common bile duct injuries , and to evaluate the operative outcome of laparoscopic cholecystectomy carried out in a major teaching hospital and review the literature . Methods Prospect ively collected data on 3,145 laparoscopic cholecystectomies performed mainly by surgical trainees in the period 1990 to 2002 using routine intraoperative cholangiography with fluoroscopy were review ed . Results The mean age of the study sample ( 65.6 % male , 34.4 % female ) was 54 years , and 16.9 % of the patients had clinical acute cholecystitis . The conversion rate to open cholecystectomy was 4.3 % . Intraoperative cholangiography was attempted for 90.7 % of the patients with a 95.9 % success rate . Five patients ( 0.16 % ) had common bile duct injuries . Four injuries had occurred in the first 5 years . One injury ( 0.06 % ) had occurred after 1995 . This injury was identified intraoperatively and repaired laparoscopically . Routine intraoperative cholangiography prevented one definite common bile duct transection . Conclusions In this series using routine intraoperative cholangiography , there was a low rate and severity of common bile duct injuries , with a high intraoperative recognition rate . There was no bile duct transection or major injury requiring common bile duct reconstruction . Although intraoperative cholangiography helped in the immediate identification of injuries and the institution of appropriate therapy , injury was not completely prevented
