Long-term follow-up on the effects of sigmoid-rectal pouch for urinary diversion.

BACKGROUND

The management of patients with common bile duct stones associated with stones in the gall bladder remains controversial.

METHODS

Over the three-year period from 1996 to 1999, patients with cholelithiasis and known choledocholithiasis, or choledocholithiasis found at laparoscopic cholecystectomy, were initially treated by placing a stent across the sphincter of Oddi. The stent was pushed along a guide wire through the cystic duct and then down the common bile duct, before the cystic duct was closed. Subsequently, the stent was used to facilitate performance of a needle knife endoscopic sphincterotomy. The stent was then removed, a cholangiography was performed and the common bile duct was cleared. Patients with persistent jaundice usually had a preoperative endoscopic retrograde cholangio-pancreatography.

RESULTS

Transcystic stenting was the 'intention-to-treat' basis of therapy for 56 of the patients. The placement of the stent only failed once when the stent became trapped in the cystic duct. Complications of the operation included: pain and jaundice (n = 2), cholangitis (n = 1), and pulmonary embolus (n = 1). The median postoperative hospitalization was 2 days (range: 1-15). Five further patients had common bile duct stones removed via a choledochotomy; a stent was placed through the choledochotomy before its closure. The selective common bile duct cannulation rate at the first endoscopic retrograde cholangio-pancreatography, was 98%. A second endoscopic retrograde cholangio-pancreatography was required in 15% of patients. The only complication of all the endoscopic procedures was a single case of mild cholangitis; there were no cases of pancreatitis.

CONCLUSION

A treatment option open to all surgeons for non-jaundiced patients with known choledocholithiasis or choledocholithiasis found at operative cholangiogram, is the transcystic stenting of the sphincter of Oddi at the time of laparoscopic cholecystectomy. At a subsequent sitting, the common bile duct can be safely cleared endoscopically using a sphincterotomy facilitated by the stent.
