Laparoscopic anatomic liver resection.

ABSTRACT: BACKGROUND: Liver resection is reputed to be one of the most difficult procedures embraced in laparoscopy. This report shows that with adequate training, anatomical liver resection including major hepatectomies can be performed. METHODS: This is a retrospective study. RESULTS: From 1995 to 2004, among 84 laparoscopic liver resections, 46 (54%) anatomical laparoscopic hepatectomies were performed in our institution by laparoscopy. Nine (20%) patients had benign disease while 37 (80%) had malignant lesions. Among those with malignant lesions, 14 patients had hepatocellular carcinoma (HCC), 18 had colorectal metastasis (CRM), while 5 had miscellaneous tumours. For benign disease, minor (two Couinaud's segments or less) and major anatomic hepatectomies were performed in five and four patients, respectively. For malignant lesions, minor and major anatomic hepatectomies were performed in 15 and 22 patients, respectively. Overall, conversion to laparotomy was necessary in 7 (15%) patients. Blood transfusion was required in five (10%) patients. One patient died of cerebral infarction 8 days after a massive peroperative haemorrhage. The overall morbidity rate was 34% whatever the type of resection. Three patients required reoperation, either for haemorrhage (n=1) and/or biliary leak (n=2). For CRM (n=18), overall and disease-free survival at 24 months (mean follow-up of 17 months) were 100% and 56%, respectively. For HCC (n=14), overall and disease-free survival at 36 months (mean follow-up of 29 months) were 91% and 65%, respectively. No port site metastasis occurred in patients with malignancy. CONCLUSIONS: After a long training with limited liver resection in superficial segments, laparoscopic anatomical minor and major resections are feasible. Short-term carcinological results seem to be similar to those obtained with laparotomy.
