Abstract

Abstract: Ascaris lumbricoides is spreading throughout the entire world. In its adult form it usually lives in the human intestine, but biliary or pancreatic complications due to the worn's infestation are not uncommon in endemic areas like Bolivia and have become a significant problem. Many authors recommended surgical treatment for the removal of the worn.In this paper we present our experiences with the endoscopic management of bilialy ascariasis.From June 1985 to August 1991, 38 patients were diagnosed as having biliary ascuriasis by means of an endoscopic retrograde cholungiography. In the duodenoscopic treatment, all of the procedures were performed under fluoroscopic control.These Ascaris lumbricoides were located in the choledocus and common hepatic ducts in 33 patients (86.8%), 3. patients had them in the gallbladder (7.9%) and 2 patients had them (5.3%) in the intrahepatic ducts.Endoscopic extractions were successful in 17 out of 20 (85.0%) non‐jaundice patients, in the other 3 cases the woms were removed surgically. In the jaundice cases, 3 of the 6 patients with woms (50.0%) were successfully treated by endoscopic extractions with simultaneous stones prior to an endoscopic sphincterotomy and the rest were treated surgically.Since no significant complications were observed after this endoscopic treatment method we recommend endoscopic extractions of biliary ascariasis.
