Spontaneous biliary perforation in infancy: Management strategies and outcomes

Abstract

PurposeInfantile spontaneous biliary perforation is rare with variable management strategies ranging from nonoperative treatment to complex operations such as biliary-enteric reconstruction. Biliary fistula and portal vein thrombosis are known complications, though outcomes are poorly defined. MethodsWe assessed the incidence of spontaneous biliary perforation in infants <1year old using a population database. Next, we describe 4 patients treated at our institution and review all reported cases within the past 25years. ResultsThe incidence of spontaneous biliary perforation is 1.5 in 1,000,000 live births. Over the past 25years, 90 cases were reported, over half of which were initially managed with a surgical drainage procedure. The most common reason for failure of this strategy was CBD obstruction. Our 4 patients were successfully managed without biliary reconstruction despite 2 presenting with CBD obstruction. Reported complications occurred in 22% of patients, most frequently biliary fistula requiring delayed biliary reconstruction. ConclusionsSurgical drainage is an effective method for treatment of infantile spontaneous biliary perforation; however a persistent biliary fistula should prompt evaluation for distal CBD obstruction. Though biliary-enteric anastomosis is the historic procedure of choice for persistent fistula, with improvements in endoscopic and percutaneous treatment, extensive biliary reconstruction may be avoided in the future.
