Risk factors for incision hernia after hepatectomy and preventive method for wound closure

Abstract

Incisional hernia is one of the most common postoperative wound complications. 6 of the 70 patients with hepatocellular carcinoma who underwent laparoscopic hepatectomy in our hospital from 2018 to 2020 had incisional hernias, with an incidence rate of 8.6％. Obesity, wound infection, and postoperative ascites were the most common backgrounds of the cases, and most of them prolapsed from the upper midline or the site of excised specimen. As a risk factor, postoperative ascites was observed, and there was a tendency for SSI to occur in many cases. In order to recognize the risks and perform evidence-based abdominal wall closure methods and preventive measures, this paper describes preventive measures for abdominal wall incisional hernia, focusing on recent findings, including the results of a risk survey in our own case.
