Clinical significance of hepatic artery variation in hepatic portal lymphadenectomy / 中国肿瘤临床

ABSTRACT

Objective:To investigate the recognition and injury prevention strategies of hepatic artery variations during hepatic portal lymphadenectomy. Methods:A retrospective analysis was performed, and 12 patients of hepatic arterial variation among 62 pa-tients with hepatic portal lymphadenectomy were the subjects. The study was conducted in the First Affiliated Hospital of Bengbu Medi-cal College between January 2013 and July 2014. The intraoperative treatment and postoperative complications were recorded. Results:Among 12 cases of hepatic artery variation, we found the following cases3 cases (25.0%) of Michels' Type III, 2 cases (16.7%) of Mi-chels' Type VI, 1 case (8.3%) of Michels' Type IX, 1 case (8.3%) of Hiatt's Type 6, 2 cases (16.7%) of spatial location variation between right hepatic artery and hepatic duct, 2 cases (16.7%) of left and right hepatic artery originating from a common hepatic artery, and 1 case (8.3%) of right hepatic artery originating from the gastroduodenal artery. No injury of hepatic artery occurred. Two cases had post-operative complications, including 1 case of pancreatic leakage and 1 case of incision infection;postoperative hemorrhage, bile leakage, hepatic abscess did not occur in these two cases. Patients recovered well in general. Conclusion:Hepatic arterial injury can be signifi-cantly reduced by the followingincreased familiarity with the various types of hepatic artery variations;complete imaging examina-tions for inspection and evaluation before surgery;and careful and meticulous operations in surgery.
