Removal of Ascaris lumbricoides from the Bile Duct Using Balloon Sphincteroplasty

Percutaneous Treatment of Extrahepatic Bile Duct Stones Assisted by Balloon Sphincteroplasty and Occlusion Balloon

OBJECTIVE To describe the technical feasibility and usefulness of extrahepatic biliary stone removal by balloon sphincteroplasty and occlusion balloon pushing. MATERIALS AND METHODS Fifteen patients with extrahepatic bile duct stones were included in this study. Endoscopic stone removal was not successful in 13 patients, and two patients refused the procedure due to endoscopy phobia. At first...

Does Sphincteroplasty Predispose to Bile Duct Cancer?

Hakamada, K., Sasaki, M., Endoh, M., Itoh, T., Morita, T. and Konn, M. (1998) Late development of bile duct cancer after sphincteroplasty: A tento twenty-two-year follow-up study. Surgery; 121, 488-492. Background: Transduodenal sphincteroplasty is designed to destroy the sphincteric muscle fibers, producing a terminal choledochoduodenostomy. In the absence of Oddi’s sphincter, intestinal conte...

Ascaris Lumbricoides

Ascaris lumbricoides--the ubiquitous roundworm.

Protocollagen proline hydroxylase from Ascaris lumbricoides.

An enzyme was found in the muscle layers of Ascaris lumbricoides which was similar to the protocollagen proline hydroxylase found in chick embryos and other vertebrates in that it synthesized 14C-hydroxyprolme when incubated with 14C-proline-labeled protocollagen from chick cartilage. The Ascaris enzyme was also similar in that it required atmospheric oxygen, a-ketoglutarate, iron, and ascorbat...
