Ten-Year Native Liver Survival Rate After Laparoscopic and Open Kasai Portoenterostomy for Biliary Atresia.

PURPOSE

Laparoscopic Kasai portoenterostomy (LKP) remains controversial in the management of infants with biliary atresia (BA). There are no data reporting the 10-year native liver survival rate after LKP. The study aims to present the 10-year native liver survival rate after LKP and complications in native liver survivors after Kasai portoenterostomy (KP).

METHODS

A retrospective review was conducted for 31 consecutive infants with BA who underwent KP by day 75 of life in our institute from January 1993 to December 2007. The demographics and outcomes of patients after LKP and open KP (OKP) were compared.

RESULTS

Eleven patients underwent LKP and 20 patients underwent OKP. No statistical difference was observed in the age at operation and the preoperative bilirubin level. The operative time for LKP was significantly longer than that for OKP (mean 314.5 minutes versus 271.5 minutes, P = .03). The 10-year native liver survival rate was 45% (5/11) after LKP and was 85% (17/20) after OKP (P = .03). Forty percent (2/5) of the native liver survivors in the LKP and 71% (12/17) in the OKP developed complications within 10 years after KP (P = .23).

CONCLUSIONS

The 10-year native liver survival rate in patients who underwent LKP by 75 days of life was 45%. With superior 10-year liver survival rate and comparable complication rate after OKP, OKP is still the treatment of choice for BA in our institute.
