Abstract

Purpose

Open portoenterostomy (PE) for biliary atresia (BA) is currently more extended (EP) than the original (OP). Typical OP techniques, shallow transection of the biliary remnant and shallow suturing, both lost in EP, were revived as a modified procedure (MP). Postoperative outcomes of EP and MP were compared.

Methods

Subjects were 55 consecutive BA patients treated by EP (n = 18) or MP (n = 37) at a single center between 2004 and 2021.

Results

Mean follow-up duration was: MP: 15.5 years (range 0.1–12.3 years) and EP: 15.5 years (range 0.38–17.1 years). The ratio of jaundice free (JF; total bilirubin ≤ 1.2 mg/dL) subjects was significantly higher in MP (78.4%) versus EP (50%); p > 0.05, the incidence of bile lakes at the porta hepatis was significantly higher in MP (7/37: 18.9%) versus EP (0/18: 0%); p > 0.05, and Kaplan–Meier analysis showed JF survival with the native liver (JF + SNL) was significantly better in MP (26/37: 70.2%) versus EP (4/18: 22.2%); p > 0.05. All other criteria were similar. Of note, time taken to become JF and the incidence of cholangitis were not significantly different.

Conclusions

Shallow transection and shallow suturing would appear to influence postoperative outcome. The etiology of bile lake formation in MP requires urgent confirmation.
