摘要："BACKGROUND & nbsp;Vascular variations are frequently encountered during surgery. Approximately thirty percent of these variations are aberrant left hepatic arteries originating from the left gastric artery.& nbsp;AIM & nbsp;To summarize the safety and feasibility of aberrant left hepatic arteries (ALHA) ligation in gastric cancer patients who underwent laparoscopic-assisted gastrectomy (LAG).& nbsp;METHODS & nbsp;The literature search was systematically performed on databases including PubMed, Embase, and Cochrane Library. The publishing date of eligible studies was from inception to June 2021.& nbsp;RESULTS & nbsp;A total of nine studies were included according to the inclusion and exclusion criteria in this review. The variation rate of ALHA ranged from 7.00% to 20.70%, and four studies compared the differences between the ALHA ligation group and the preservation group. Only one study showed worse postoperative outcomes in the ALHA ligation group. In all the included studies, a significant difference was found between the ALHA ligation group and the preservation group in terms of postoperative liver enzymes after LAG. However, there was no significant difference in the number of retrieved lymph nodes between the two groups.& nbsp;CONCLUSION & nbsp;In conclusion, it is not always safe and feasible for surgeons to ligate the ALHA during LAG surgery, and it is necessary for gastric cancer patients to undergo preoperative examination to clarify the ALHA subtypes, measure the diameter of the ALHA, and determine whether the patients have chronic liver disease."
