Suspected biliary complications after laparoscopic and open cholecystectomy leading to endoscopic cholangiography: a...

To study how suspected postoperative biliary complications are influenced by surgical technique, we compared clinical profiles of 63 patients referred for ERCP after open (OC) and laparoscopic cholecystectomy (LC) over a four-year period. ERCP was not performed for postoperative pain alone and only six (9.5%) studies were normal. Referrals after LC were younger (mean 39.1 vs 53.6 years, P < 0.001) and ERCP was requested earlier (mean 71.6 vs 2360 days, P < 0.001) in the postoperative course. Choledocholithiasis (CDL) alone, the most common finding, was successfully managed with a single ERCP in 97.2% of cases. CDL after LC occurred in younger patients (35.5 vs 58.9 years, P < 0.01) who presented earlier (mean 98.6 days vs 5.1 years, P < 0.01), without biliary ductal dilatation (P < 0.01). Although CDL after LC was associated with higher ALT and bilirubin levels than after OC, the difference was not statistically significant. Cystic duct leaks (LC: six patients, OC: four patients) were typically associated with CDL after OC and 90% resolved with endoscopic therapy. Biliary ligation (four cases) was managed successfully with choledochojejunostomy. We conclude that findings at ERCP for suspected biliary obstruction or injury after OC or LC are similar and usually can be endoscopically managed. After LC, referrals currently are younger, present much earlier, and retained stones are less likely to be associated with ductal dilatation than after OC.
