Periampullary carcinoma and carcinoma head of pancreas are common causes of obstruction at the lower end of the common bile duct. Whenever possible, surgical resection in the form of Whipple Pancreaticoduodenectomy (WPD) is the treatment of choice. However, this operation is associated with a substantial postoperative morbidity and mortality. With advances in surgical techniques and postoperative care there has been a decrease in the operative mortality. However, the postoperative morbidity remains high varying between 5%-64%. Of the various risk factors, the degree of jaundice as indicated by the serum bilirubin levels has been associated with an increased risk of complications. Preoperative biliary drainage has been tried to decrease the serum bilirubin levels and consequently decrease postoperative morbidity and mortality. Internal biliary drainage can be achieved by surgical cholecystojejunostomy or endoscopic bile duct stenting. Endoscopic stenting can be done as a day care procedure under conscious sedation, but involves insertion of a foreign body (stent), which results in introduction of bacteria into the bile and problems of postoperative infection. Also, endoscopic stenting before surgery may result in difficulty in dissecting around the common bile duct during the surgical procedure. While the surgical bilioenteric bypass has the advantage that no foreign body is inserted into the biliary tree and hence the likelihood of sepsis is low, it requires anesthesia and involves a surgical incision.
