BACKGROUND: The portoenterostomy (PE) procedure for treating biliary atresia (BA) has been so repeatedly modified that it currently hardly resembles Kasai's original PE (KOPE). Now PE involves an extended lateral dissection and a wide anastomosis (extended PE: EPE). We reappraised KOPE and created our-KOPE (OKOPE) by adhering strictly to its principles and techniques. We compared outcome of EPE and OKOPE. METHODS: We reviewed 24 consecutive cases of PE for BA performed at our institution from 2005 to 2011. Thirteen had EPE, and 11 had OKOPE. Body weight, serum total bilirubin, age at PE, total steroid dosage required for jaundice clearance (JC: total bilirubin ≤1.2 mg/dL), JC ratio, time taken for JC, survival rate with the native liver (SNL), and SNL after JC (SNL + JC) were compared at 16 months (shortest mean follow-up). Postoperative management protocols were identical for both groups. RESULTS: The JC ratio was significantly higher for OKOPE (90.9%) than EPE (46.2%) (p = 0.02). Both SNL and SNL + JC were significantly higher for OKOPE (90.9 and 72.7%) than EPE (30.8 and 30.8%) (p = 0.003 and p = 0.04, respectively). All other variables were similar for both groups. CONCLUSIONS: Jaundice clearance following OKOPE would appear to be better than after EPE.
