Laparoscopic transcystic duct balloon dilatation of the sphincter of Oddi.

Balloon dilatation of the sphincter of Oddi has been performed via a laparoscopic transcystic duct technique. Small common duct stones and stone debris have been successfully lavaged into the duodenum in 17 of 20 cases (85%) by this method. Postoperative hyperamylasemia was noted in four patients. Mild clinical pancreatitis was observed in three patients (15%). Further evaluation of this technique as an adjunct to laparoscopic common bile duct stone extraction is warranted.
