Background and study aims: Overall, 5 % to 15 % of patients undergoing cholecystectomy for cholelithiasis have
concomitant bile duct stones, and the incidence of choledocholithiasis increases with
age. There is no clear consensus on the best therapeutic approach (endoscopic versus
surgical).
Patients and methods: A prospective randomized controlled clinical trial was performed to compare three
treatment options for patients with choledocholithiasis at the National Center for
Minimally Invasive Surgery in Havana, Cuba from November 2007 to November 2011. The
patients were randomized in three groups. Group I: patients who underwent intraoperative
cholangiography (IOC) to confirm the choledocholithiasis followed by laparoscopic
cholecystectomy (LC) associated with intraoperative endoscopic retrograde cholangiopancreatography
(ERCP), group II: patients who underwent preoperative ERCP followed by LC during the
same hospital admission and group III: patients who underwent IOC to confirm the choledocholithiasis
followed by LC associated with laparoscopic common bile duct exploration (LCBDE).
Results: A total of 300 patients with suspected choledocholithiasis were included in the trial
and were randomized. As a result, a total of 134 patients were diagnosed with the
presence of choledocholithiasis and treated during the study period. There were no
significant differences in success rates of ductal stone clearance, but retained stone,
postoperative complications and length of hospital stay were better in group I.
Conclusions: Intraoperative ERCP/ES shows a higher rate of common bile duct stones clearance,
a shorter hospital stay, and lower morbidity, but further research with a larger study
population is necessary to determine the additional benefits of this procedure. The
results to date suggests that in appropriate patients, single-stage treatments are
the best options.
