An easy and effective method of cholangiography in laparoscopic cholecystectomy: laparoscopic
1Belmont District Hospital, New South Wales, Australia.
Background:
There is ample evidence that the incidence of operative cholangiography has declined since the introduction of laparoscopic cholecystectomy. It has been suggested that one of the reasons for this decline is the technical difficulty of cystic duct catheterization. A method of cholangiography which does not require such catheterization has been developed by others. This paper examines the ease and effectiveness of operative cholangiography performed by direct puncture of the gall-bladder.
Methods:
A retrospective study was made of the records of 380 consecutive patients who underwent attempted laparoscopic cholecystectomy. After exclusion of patients in whom laparoscopic cholecystectomy was abandoned in favour of open cholecystectomy and those patients in whom operative cholangiography was not attempted, the records of 325 patients were available to the study. The operation notes of each patient were studied to determine whether, in the operator's opinion, a successful cholangiogram had been obtained.
Results:
There were 290 patients in whom cholangiography was attempted using direct gall-bladder puncture (cholecystocholangiography (CCC)). There were 35 patients in whom cholangiography was attempted via cystic duct cannulation (CDC). Cholecystocholangiography was successful in 86% of those cases in which it was attempted. Cystic duct cannulation was successful in 83% of those cases in which it was attempted.
Conclusion:
Cholecystocholangiography is a valid alternative to cystic duct catheterization in its ability to achieve intra-operative cholangiography in the setting of laparoscopic cholecystectomy.
