Laparoscopic revision of Kasai portoenterostomy after initial laparoscopic portoenterostomy in patients with biliary atresia: a limited but positive effect on native liver survival.

Abstract

It is important for patients with biliary atresia (BA) to retain the native liver after Kasai portoenterostomy (PE). Laparoscopic PE (Lap-PE) is standard, whereas laparoscopic revision of PE (Lap-revision) is performed as needed. We report the medium-term outcomes of Lap-revision. We retrospectively reviewed the demographics and outcomes of 63 patients who underwent Lap-PE between 2013 and 2021. Indications for revision included recurrent jaundice, repeat cholangitis, and persistent jaundice with temporary biliary excretion following the initial PE. We compared liver transplantation (LT) data of patients who underwent Lap-revision with those of patients who did not. Lap-revision was performed in 20 patients. Of those 17 (excluding the two who were jaundice-free before the age of 1, and the one who underwent open conversion for bleeding), 11 (65%) were jaundice-free 1year after Lap-revision. The surgical parameters of LT did not differ between patients who underwent Lap-revision and those who did not. Lap-revision for patients with BA had a limited but positive effect on native liver survival and did not adversely affect subsequent LT. Therefore, Lap-revision could be second-line standard therapy in patients with BA who have demonstrated biliary drainage at least once after initial PE.
