Survival With Own Liver of Conventional Versus Laparoscopic Kasai for Biliary Atresia

Objective: A prospective observational study to compare survival with own liver in laparoscopic versus conventional Kasai portoenterostomy in patients with biliary atresia. Summary Background Data: Available studies on laparoscopic versus conventional Kasai portoenterostomy focus on short-term results, include limited numbers of patients and have design limitations. Methods: A consecutive series of patients underwent laparoscopic Kasai procedure from 2006 to 2007. Conventionally operated control patients consisted of a consecutive series of infants with biliary atresia operated from August 2003 to 2006. All data were ascertained prospectively using the European Biliary Atresia Registry / EBAR registration forms. Primary outcome measure was survival with own liver 6 months after Kasai without being listed for liver transplantation. An interim analysis was planned after data became available for the first 12 patients who underwent laparoscopic Kasai procedure. In case of a significantly different interim outcome the follow-up period should be extended to 24 months until a final decision should be drawn.
