Innovative modification of the hepatic portoenterostomy. Our experience of treating biliary atresia

We modified conventional hepatic portoenterostomy by pulling the remnant fibrous mass caudally and placing 5 or 6 numbered and individually clamped absorbable 5-0 double-needle sutures horizontally in the liver surface of the posterior side of the remnant fibrous mass before excision and apposing the posterior and anterior margins of the hepatic portoenterostomy to resemble a flattened isosceles triangle. Our technique was used to treat 14 cases of biliary atresia. Good postoperative biliary excretion (serum total bilirubin, <2 mg/dL) was achieved in 13 (92.9%) of 14 patients.
