Brief Summary:
This study evaluated laparoscopic (videosurgery) versus conventional (open surgery) Kasai portoenterostomy (anastomosis of small intestine to the liver hilus) in children with biliary atresia. The study was stopped due to lower survival with native liver 6 months after the laparoscopic operation. Follow-up after 24 months confirmed superior results after conventional operation.

Condition or disease Intervention/treatment Phase
Biliary Atresia Procedure: Laparoscopic Kasai operation Not Applicable

Detailed Description:


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.


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.

Arm Intervention/treatment
Experimental: Lap Kasai
Patients in this arm had their necessary Kasai procedure in a laparoscopic way.
Procedure: Laparoscopic Kasai operation
the Kasai procedure (hepatoportoenterostomy) is performed laparoscopically, thus not in open surgery.
Other Names:
  • hepatoportoenterostomy
  • coelioscopie

Primary Outcome Measures :
  1. Survival with own liver at 6 months after the Kasai operation without beeing listed for liver transplantation [ Time Frame: one year ]

Secondary Outcome Measures :
  1. Jaundice free survival confirmed by serum bilirubin < 20 umol/l [ Time Frame: 6 months ]
  2. Feasibility of laparoscopic Kasai with regard to conversions and revisions [ Time Frame: 3 months ]
