Excision of a part of the bile duct as an iatrogenic injury typical for laparoscopic cholecystectomy - characteristics, treatment and long-term results, based on own material

Abstract

Introduction: Cholecystectomy is associated with the risk of bile duct injury (BDI). The nature of the injury in laparoscopic cholecystectomy (LC) cases seems to be more serious. Aim: We present an analysis of long-term results of the treatment of patients who underwent operations at our department due to iatrogenic excision of a part of the bile duct (EPBD). Material and methods: Out of all 120 patients treated for BDI in our department we selected a group of 40 with EPBD. In all cases the corrective operation was hepaticojejunostomy. The median follow-up time was 157 (56-249) months. We evaluated risk factors for EPBD during LC compared to open cholecystectomy (OC). Results: Among bile duct injuries referred to our centre, EPBD occurred more frequently during LC (46.7%) compared to OC (11%), p < 0.001. Injuries located in the hepatic hilum occurred more often in the case of LC (68.6%) than OC (20%), p = 0.056. We did not find a difference in the frequency of EPBD between LC and OC groups depending on the presence of acute or chronic cholecystitis. The narrow common hepatic duct was reported more frequently in the LC (68.6%) vs. OC (20%) group, p = 0.056. Satisfactory long-term reconstructive treatment results were observed in 36 (90%) of 40 patients. Conclusions: Excision of a part of the bile duct occurs more often during LC than OC. It is often located in the hepatic hilum. Presence of a narrow common hepatic duct is a risk factor for EPBD during LC. Large diameter hepaticojejunostomy is a reconstructive procedure that promises good long-term results.
