OBJECTIVE. To review results of laparoscopic liver resections, particularly in those patients with hepatic malignancy and recurrent pyogenic cholangitis.

DESIGN. Retrospective analysis.

SETTING. Minimal access surgery training centre, Hong Kong.

PATIENTS. Patients with pathologies located at anterio-inferio-lateral segments (Couinaud segments 2, 3, 4b, 5, 6) for laparoscopic resection were recruited during the period 1998 to 2005. Patients were excluded from review if they had: pathologies at central locations and the superior and posterior segments (4a, 7, 8), large tumours (>5 cm in diameter), and those close to major vasculature or the liver hilum.

RESULTS. During the study period, we attempted 40 such laparoscopic liver resections, excluding marsupialisations and resections for simple liver cysts. There were 20 female and 20 male patients, with a mean age of 57 (standard deviation, 13; range, 29-81) years. All but one underwent a successful laparoscopic operation. Pathology included hepatocellular carcinoma (n=17), recurrent pyogenic cholangitis (n=14), colorectal liver metastasis (n=4), benign liver tumour (n=4), and intrahepatic cholangiocarcinoma (n=1). All except four were hand-assisted laparoscopic liver resections. The mean operating time was 169 (range, 60-290) minutes and mean blood loss amounted to 270 mL (range, 0-1000 mL). Complications occurred in eight (20%) patients, which included six wound infections, one postoperative bile leak, and two incisional hernias. There was no operative or hospital mortality. For hepatocellular carcinoma, clear resection (>10 mm) was achieved in all except five patients, and the 1-year and 2-year survival rates were 86% and 59% respectively. Favourable results were also obtained for resections in patients with recurrent pyogenic cholangitis; after a mean (standard deviation) follow-up of 29 (23) months, only one was readmitted (for cholangitis).

CONCLUSION. In appropriately selected patients, laparoscopic liver resection is feasible and safe, and achieves acceptable survival among individuals with hepatic malignancy and very favourable long-term outcomes in those with recurrent pyogenic cholangitis undergoing hand-assisted laparoscopic segmentectomy.
