Treatment of biliary atresia: microsurgery for hepatic portoenterostomy.

Microsurgery was used for hepatic portoenterostomy as the treatment of biliary atresia in 46 patients whom we treated since 1972. The microscope had a higher power (eight or ten times) magnification. As for the results of the operative procedure with the microscope, of 46 patients, 32 (70 percent) showed satisfactory bile flow postoperatively.
