Laparoscopic Transduodenal Sphincteroplasty

Abstract

Common bile duct stones are a difficult problem, often leading to conversion to an open operation or repeated endoscopic procedures. Both strategies are associated with added morbidity. A new technique was developed to perform a traditional sphincteroplasty using minimally invasive methods. The procedure was performed on two patients with distal common bile duct stones; each patient had previously undergone at least two unsuccessful preoperative endoscopic retrograde cholangiopancreatography procedures by at least two different experienced endoscopists. In both patients, a laparoscopic transduodenal sphincteroplasty was successfully completed. A transduodenal common bile duct exploration was performed at the time of sphincterotomy, successfully clearing the common bile duct in both cases. There were no untoward postoperative sequelae. Follow-up at one year was satisfactory in both patients. Laparoscopic transduodenal sphincteroplasty can be safely performed in patients with common bile duct stones refractory to endoscopic retrograde cholangiopancreatography. This technique offers a new approach to the management of common bile duct stones, and can spare patients the need for an open operation or subsequent endoscopic procedures.
