Ten-year experience of totally laparoscopic liver resection in a single institution

Background: Recent developments in liver surgery include the introduction of laparoscopic liver resection. The aim of the present study was to review a single institution's 10-year experience of totally laparoscopic liver resection (TLLR). Methods: Between May 1997 and April 2008, 82 patients underwent TLLR for hepatocellular carcinoma (HCC) (37 patients), liver metastases (39) and benign liver lesions (six). Operations included 69 laparoscopic wedge resections, 11 laparoscopic left lateral sectionectomies and two thoracoscopic wedge resections. Nine patients underwent simultaneous laparoscopic resection of colorectal primary cancer and synchronous liver metastases. Results: Median operating time was 177 (range 70-430) min and blood loss 64 (range 1-917) ml. Median tumour size and surgical margin were 25 (range 15-85) and 6 (range 0-40) mm respectively. One procedure was converted to a laparoscopically assisted hepatectomy. Three patients developed complications. Median postoperative stay was 9 (range 3-37) days. The overall 5-year survival rate after surgery for HCC and colorectal metastases was 53 and 64 per cent respectively. Conclusion: TLLR can be performed safely for a variety of primary and secondary liver tumours, and seems to offer at least short-term benefits in selected patients.
