Laparoscopic liver surgery is gaining increasing acceptance worldwide, but its frontiers are constantly challenged. Laparoendoscopic single-site surgery (LESS) has been performed for various organs, but the feasibility of LESS hepatectomies has yet to be explored fully.
From May 2010 to March 2011, seven patients underwent LESS minor hepatectomies. Patient demographic, operative, and clinical data were reviewed.
Five left lateral sectionectomies, one segment 3, and one segment 5 resection were performed. The median operative time was 142 min (range, 104-171 min), and the median blood loss was 200 ml (range, 100-450 ml). The median hospital stay was 3 days (range, 1-11 days). For all the patients, the indications for surgery were suspected malignant tumors, and the surgical resection margins were clear for every patient.
Laparoendoscopic single-site minor hepatectomy is a novel modification to traditional laparoscopic surgery. The method is safe and feasible without any compromise to oncologic safety for selected patients with hepatocellular carcinoma (HCC) and colorectal liver metastases that are peripheral and smaller than 5 cm in size.
腹腔镜肝手术在全球范围内越来越被接受，但它的边界不断受到挑战。经脐单孔腹腔镜手术（LESS）已应用于各种器官，但 LESS 肝切除术的可行性仍有待充分探索。
2010 年 5 月至 2011 年 3 月，7 例患者接受了 LESS 小肝癌切除术。回顾患者的人口统计学、手术和临床资料。
5 例行左外叶切除术，1 例行 3 段切除术，1 例行 5 段切除术。中位手术时间为 142 分钟（范围 104-171 分钟），中位出血量为 200 毫升（范围 100-450 毫升）。中位住院时间为 3 天（范围 1-11 天）。所有患者的手术指征均为疑恶性肿瘤，且每位患者的手术切除边界均明确。
经脐单孔腹腔镜小肝癌切除术是传统腹腔镜手术的一种新的改良方法。对于外周、直径小于 5cm 的 HCC 和结直肠癌肝转移的选定患者，该方法安全可行，不影响肿瘤安全性。
