Hepatic arterial injuries after percutaneous biliary interventions in the era of laparoscopic surgery and liver transplantation: experience with 930 patients.

Abstract：

PURPOSE:To retrospectively determine if patients with a history of intraoperative bile duct injury or liver transplantation have an increased risk for arterial injury (AI) during percutaneous transhepatic cholangiography (PTC) and percutaneous transhepatic biliary drainage (PTBD) compared with the risk of AI established in the 1970s and 1980s. MATERIALS AND METHODS:This study was approved by the committee on human research and was deemed compliant with the Health Insurance Portability and Accountability Act. The informed consent requirement was waived. Records of 1394 procedures (307 PTCs, 1087 PTBDs) performed in 930 patients (445 male, 485 female; age range, 4 months to 99 years) over the past 13 years were retrospectively reviewed. The rate of AI was determined, and demographic, pathologic, technical, and laboratory variables were tested for association with increased risk of AI by using generalized estimating equation analysis. RESULTS:AIs were encountered after 30 (2.2%) biliary procedures. No significant difference in the rate of AI was seen among the groups of patients with malignant biliary obstruction (1.8%), history of bile duct injury (2.2%), or complications of liver transplantation (2.6%). Patients who underwent PTBD had a higher risk of AI than did patients who underwent PTC (2.6% vs 0.7%); however, this difference was not significant (P = .06). Ongoing hemobilia was seen in 26 (87%) of the patients, which made it the most common sign of AI, and it had a 94% positive predictive value for AI. A postprocedure decrease in the hematocrit level of more than 13% was seen only in the setting of AI, and it occurred in only three (10%) of patients with AIs. CONCLUSION:PTC and PTBD performed for management of bile duct injury and complications of liver transplantation are not associated with an increased risk of hepatic AIs compared with the risk of AI reported in the 1970s and 1980s.
