Laparoscopic management of common bile duct stones.
We reviewed our experience with the management of common bile duct (CBD) stones in 100 consecutive patients treated laparoscopically during the past 9 years (1990-1998) and evaluated the advantages, disadvantages, and feasibility of the treatment, to elucidate reasonable therapeutic strategies for patients harboring CBD stones. We conclude that the most rational management of CBD stones is that which is decided according to the size of the CBD, which, in turn, depends on the size, number, and location of stones. The cystic duct in patients with a non-dilated CBD is narrow, because the size of the CBD depends on the size and number of stones that have migrated through the narrow cystic duct, and the stones in the non-dilated CBD are therefore usually small in size and number. Patients with a dilated CBD, however, are good candidates to undergo single-stage laparoscopic treatment. In our Department, therefore, even if complete removal of stones has failed in patients with non-dilated CBD, further choledochotomy is not carried out, and a C-tube is placed through the cystic duct for a subsequent postoperative transduodenal approach, because laparoscopic transcystic CBD exploration and choledochotomy may not be always feasible in those patients with non-dilated CBD, and spontaneous migration of small stones into the duodenum is frequently noted. In fact, some stones demonstrated on intraoperative cholangiograms were not revealed by postoperative cholangiography. In contrast, retained stones detected postoperatively were successfully removed by postoperative endoscopic sphincterotomy (EST), the endoscopic papillary balloon dilatation technique (EPBDT), or postoperative cholangioscopy (POCS) without any injury to the sphincter of Oddi. With this approach, we believe that the causes of stone recurrence can be avoided in the majority of cases.
