Abstract:
Objective To probe the causes,early recognition and effective therapy of posttraumatic biloma.Methods The data of all patients with the injury of the liver and bile duct treated in our center during the past 10 years were reviewed.Patients,diagnosed with biloma were retrospectively analyzed in respects of sex,age,cause of biloma,methods and efficacy of diagnosis and treatment.Results There were 46 patients with biloma.Of them,40 were found after liver trauma of grade Ⅲ-Ⅴ.The incidence of biloma was 15.2％ (40/263).In grade Ⅳ,Ⅴ,and Ⅲ,it was 22.6％ (31/137) and 7.1％ (9/126) respectively (x2 =12.20,P ＜ 0.01) and in blunt and penetrating injury,it was 19.3％ (35/181) and 6.1％ (5/82) respectively (x2 =7.67,P ＜ 0.01).Of these 40,36 were found during the course of conservative therapy of severe liver trauma; and 4 were found after laparotomy for the liver trauma.The remaining 6 cases of biloma had a history of injury to extrahepatic bile duct with a incidence of 18.8％(6/32).All 46 patients received spiral CT scaning plus MRI in 9,and ERCP in 11.Of those 40 with biloma after severe liver trauma,28 were cured by ultrasound-guided or computed tomography scan-guided pigtail drainage; and the remaining 12,in whom the biloma volume ＜ 30 cm3 resolved spontaneously.Six patients in whom the biloma as a result of injury to extrahepatic bile duct were cured by surgical intervention.There was no death and complication related with the therapy of biloma.Conclusions Attention should be given to biloma formation,when nonoperative therapy is exercised for severe liver trauma.Ultrasound-or CT scan-guided pigtail drainage is an effective option,but those due to injury of extrahepatic bile duct require surgical intervention.
