Biliary dilatation and strictures (BDS) are well recognized after liver transplantation but not reported after composite liver-small bowel transplantation (CLSBT). We aimed to describe and propose a classification of BDS in children undergoing CLSBT and analyze the potential risk factors.Biliary complications of 47 consecutive children undergoing CLSBT were reviewed and classified according to presentation, location, and intervention required. The following variables were studied: small recipient (weight,10 kg), donor-recipient weight ratio, liver/bowel graft reduction/not, partial/full pancreas, liver/bowel rejection, and median cold ischemia time (454 min).Twenty-one (45%) children developed BDS at median 190 days (22 [7-138] months follow-up). Five distinct biliary lesions were identified. Most of the BDS (14/21; 67%) consisted of sphincter dysfunction-related bile duct dilatation (type I), whereas others (7/21; 33%) comprised extrahepatic bile duct (type II; n=3), hilar (type III; n=1), segmental (type IV; n=1), and diffuse (type V; n=2) intrahepatic strictures. None of the graft reduction strategies or other variables studied demonstrated a significant association with BDS. Therapeutic intervention was required in 1 of 14 type I and four of seven type II to V BDS in the form of percutaneous biliary dilatation with or without drainage.This article identifies BDS after CLSBT as a frequent late complication after CLSBT, which has a benign outcome in most cases. The natural history of children with extrahepatic and intrahepatic strictures is not yet clear and will need multicenter prospective studies.

BACKGROUND: Intestinal transplantation is known to be associated with a high risk of early complications and mortality. METHODS: We analyzed prospective data of 51 primary small bowel transplantations from December 1999 to August 2009 and identified perioperative factors that impact on early mortality (≤6 months after transplantation) after isolated intestinal (IITx; n=12) and combined liver-intestinal transplantation (CLITx group; n=39). RESULTS: Ten patients died during the first 6 months after transplantation, all of them in CLITx group (n=10/51, 19%). Multivariate analyses demonstrated intraoperative red blood cell transfusion greater than 70 mL/kg (P=0.019, odds ratio [OR]=13.79) and base excess 30-min after reperfusion less than -16 (P=0.001, OR=14.05), thrombocytopenia (
