Outcomes of ileocolic conduit for biliary drainage in infants with biliary atresia; comparison with Roux-en-Y type reconstruction.
This study was undertaken to define the role of an ileocolic conduit that was devised as anti-reflux procedure in comparative study with Roux-en-Y type reconstruction in infants with biliary atresia treated at a single institution. The ileocolic conduit (IC) consisted of 30 cm of distal ileum anastomosed to the portahepatis and a 10-cm segment of ascending colon vented through the abdominal wall, which was later anastomosed to the second portion of the duodenum. In the Roux-en-Y type reconstruction (RY), 40 to 60 cm of jejunum was used for the hepatic limb. Twenty-three infants in group IC and 16 infants in group RY were entered in this study. Mean ages at definitive surgery were 65.3 +/- 23.1 days for group IC and 65.0 +/- 19.5 days for group RY. The two groups were compared for the postoperative outcomes in terms of bile excretion, incidence of cholangitis, esophageal varices, survival rate, and the effects on physical development. The follow-up ranged from 4 to 15 years. Bile excretion was obtained in all infants in both groups. Twenty infants (87.0%) in group IC and 10 infants (62.5%) in group RY became anicteric. Cholangitis occurred in 60.9% of group IC, compared with 83.3% for group RY, in which 6 infants required revision to complete diversion of Roux-en-Y limb (Suruga II). There was the same occurrence rate of esophageal varices for both groups. However, the varices tended to develop later in group IC (53.0 +/- 18.4 months) than in group RY (12.7 +/- 6.0 months) (P < .02).(ABSTRACT TRUNCATED AT 250 WORDS)
