Laparoscopic liver resection: experience of 53 procedures at a single center.

Background/purpose: The short-term outcome following laparoscopic liver resection at a single center is presented.

Methods: Fifty-three procedures were carried out in 47 patients, between August 1998 and April 2004 (6 patients were resected on two occasions). A previous laparotomy and/or hepatectomy had been done in 83% and 26% of the procedures, respectively. Colorectal metastasis was the main indication for treatment (42/53). A total laparoscopic approach was applied.

Results: Three of the 53 (6%) procedures were converted to laparotomy. In one additional procedure, radiofrequency ablation was done instead of resection. Sixty liver resections were done during the 49 procedures completed laparoscopically as planned (9 patients had concomitant resections performed). Nonanatomic (45/60) and anatomic (15/60; left lobectomies) resections were done. Tumor tissue was found in the resection margins of 6% of the specimens. The free margin was very short in 8% of the specimens. The morbidity was 16%. There was no mortality. Blood transfusions were given following 26% of the procedures. The median hospital stay was 3.5 days (range, 1-14 days) and the median number of days on which there was a need for opioids was 1 (range, 0-11 days).

Conclusions: Laparoscopic liver resection can be performed safely and seems to offer short-term benefits to the patients. Randomized studies are required to further evaluate the potential benefits of this treatment.
