Medium-term outcomes after laparoscopic revision of laparoscopic Kasai portoenterostomy in patients with biliary atresia
Objective To determine whether revision laparoscopic Kasai portoenterostomy (RLKPE) is a viable treatment option for patients with biliary atresia (BA) who underwent initially successful laparoscopic Kasai portoenterostomy (ILKPE). Methods The medical records of 312 patients with nonsyndromic BA who underwent ILKPE between May 2009 and May 2017 were retrospectively reviewed. The patients were divided into three groups according to their outcomes after ILKPE: group A: 25 patients who underwent
... nts who underwent RLKPE; group B: 203 patients who underwent ILKPE and required no further surgical intervention; and group C: 84 patients with failed ILKPE who either died or required liver transplantation for survival. The 3-year and 5-year survival with native liver (SNL) rates were compared between groups A and B and between groups A and C. Among the 25 patients in group A, the perioperative data of RLKPE were compared with those of ILKPE. Results Of the 312 patients who underwent ILKPE, 228 reached the normal bilirubin concentration range within 6 months postoperatively. Among them, 25 patients with a sudden cessation of bile flow underwent RLKPE. Adequate biliary drainage evidenced by normalized conjugated bilirubin levels was achieved in 80% of the patients who underwent RLKPE. The perioperative variables, including operative time, blood loss, rate of conversion to open surgery and complications of RLKPE, were not significantly different between RLKPE and ILKPE. The 3-year and 5-year SNL rates in patients after RLKPE were 64.0% and 52.0%, respectively, which were not significantly different from the corresponding 86.2% and 73.9% in patients after unrevised ILKPE (P > 0.05) but were significantly better than the corresponding values of group C (P < 0.01). Conclusion Our data demonstrated that with appropriate patient selection, RPLKE can be a viable and effective treatment opinion in patients who experience sudden cessation of bile drainage after ILKPE. RPLKE can delay the need for liver transplantation, yielding encouraging medium-term patient outcomes.
