Ethylene-Vinyl Alcohol Copolymer Endobiliary Obliteration of Hepatic Segments in a Patient with Isolated Bile Leaks

摘要

A 54-year-old woman with a symptomatic giant hepatic hemangioma underwent an extended left hepatic trisegmentectomy complicated by 250-350 mL/d postoperative bilious drainage. After 5 months of therapy, drainage was unabated, and the patient was no longer a surgical candidate. Sinography revealed three distinct isolated bile duct leaks involving segments 6, 7, and 8. Endobiliary segmentectomy was achieved by obliterating the isolated systems with ethylene-vinyl alcohol copolymer (Onyx; ev3, Plymouth, Minnesota) during three fluoroscopic procedures. Bilious leaks were successfully eliminated, and compensatory hypertrophy of noninvolved liver occurred. At 2 years from the last embolization procedure, the patient remained; asymptomatic with no bilious leak.
