This study is to evaluate the need for preoperative cholangiography du
ring laparoscopic cholecystectomy when endoscopic retrograde cholangio
pancreatography (ERCP) is available. Over a period of four years, 1105
consecutive patients had laparoscopic cholecystectomy. All patients,
in addition to their clinical assessment, had routine liver function t
ests (LFTs) and ultrasound (US) examination of the biliary tract. Preo
perative ERCP was performed (diagnostic and/or therapeutic) in 107 (9.
6%) of the patients. The indications for ERCP were one or more of the
following: 1) abnormal liver function test, 74 patients; 2) jaundice,
37 patients; 3) common bile duct (CBD) stone seen in US, 36 patients,
and/or CBD dilatation, 46 patients; and 4) pancreatitis, 20 patients.
In 41 out of 107 (38%) patients, CBD stones were present and cleared e
ndoscopically. Postoperative ERCP was necessary in eight patients: to
remove retained stones in the CBD (two patients), to stop bile leak (t
wo patients), and to investigate the persistent abnormal LFTs in the r
emaining patients. The number of patients who had evidence of retained
CBD stone following laparoscopic cholecystectomy was only two. In bot
h patients, endoscopic removal was successful. Therefore, it is clear
that operative cholangiography in laparoscopic cholecystectomy is not
essential if there is a reasonable facility for ERCP.
