Endoscopic management of early postoperative biliary ascariasis in patients with biliary tract surgery.
Bile leak and residual stones are well known complications of biliary tract surgery. In endemic areas of ascariasis, invasion of the biliary tract by roundworms during the early postoperative period is an infrequent but serious complication. The present study describes the endoscopic management of postoperative biliary ascariasis in 19 consecutive patients. There were 5 men and 14 women with a mean age of 33.3 +/- 6.3 years. All patients had undergone cholecystectomy, with choledocholithotomy and placement of a T-tube in 13 (68.4%) patients. Eight (42.1%) patients including two with T-tubes were acutely sick at referral. Altogether, 16 (84.2%) patients had widened papillae due to previous endoscopic sphincterotomy (3 patients) or recent dilatation of the sphincter of Oddi by Bake's dilators (13 patients). All patients with a T-tube in situ had undergone unsuccessful attempts to remove the worms by flushing saline through the T-tube. Endoscopic retrograde cholangiopancreatography was performed 4 to 16 days after biliary tract surgery and revealed roundworms in the common bile duct in 10 patients, in the hepatic ducts in 2, or in both ducts in 7. Three patients had coexisting biliary leakage: from the cystic duct stump in two and from a T-tube track in one. Endoscopic treatment consisted of extracting the worms from the biliary tree and placing stents in those with coexisting leakage. Endoscopic success was defined as complete worm extraction and resolution of biliary leakage and was achieved in all patients. Complications occurred in one (5.3%) patient. We concluded that endoscopic management is an effective, safe approach for extracting ascarids from the biliary tree during the early postoperative period. It reduces the hospital stay, avoids T-tube-related complications, and permits a postoperative complication to be treated using a nonsurgical method.
