METHODS: In an 18-year period, among 603 patients referred to our hospital for surgical treatment of complex bile duct injuries, 53 presented involvement of the hilar confluence classified as Strasberg E4 injuries. Imagenological studies, mainly magnetic resonance imaging showed a loss of confluence. The files of these patients were analyzed and general data were recorded, including type of operation and postoperative outcome with emphasis on postoperative cholangitis, liver function test and quality of life. The mean time of follow-up was of 55.9 ± 52.9 mo(median = 38.5, minimum = 2, maximum = 181.2). All other patients with Strasberg A, B, C, D, E1, E2, E3, or E5 biliary injuries were excluded from this study.RESULTS: Patients were divided in three groups: G1(n = 21): Construction of neoconfluence + Roux-en-Y hepatojejunostomy. G2(n = 26): Roux-en-Y portoenterostomy. G3(n = 6): Double(right and left) Rouxen-Y hepatojejunostomy. Cholangitis was recorded in two patients in group 1, in 14 patients in group 2, and in one patient in group 3. All of them required transhepatic instrumentation of the anastomosis and six patients needed live transplantation.CONCLUSION: Loss of confluence represents a surgicalchallenge. There are several treatment options at different stages. Roux-en-Y bilioenteric anastomosis(neoconfluence, double-barrel anastomosis, portoenterostomy) is the treatment of choice, and when it is technically possible, building of a neoconfluence has better outcomes. When liver cirrhosis is shown, liver transplantation is the best choice.展开更多
