> Laparoscopic liver resections : a single center experience.


Background : Since the first reported laparoscopic liver resection (Gagner 1992) an increasing number of small prospective studies have been published. They have shown encouraging results on the feasibility and safety of the procedure. This paper prospectively evaluated the results of a single center’s experience with elective liver resections.

Methods : From January 1995 to January 2004 a prospective study of laparoscopic liver resections was undertaken in 31 patients with preoperative diagnosis of benign lesions (13 cases, 42.4%), hepatocellular carcinoma in absence of complicated cirrhosis (3 cases, 9.1%), and liver metastases (15 cases, 45.5%). Mean tumor size was 34.9 mm (range 10 - 100 mm).

Results : The procedures included 11 (37.9%) major hepatectomies and 21 (62.1%) minor resections (one patient was submitted to repeat laparoscopic liver resection). There were 3 conversions to open. Mean blood loss was 210 ml (range 0 – 700 ml). Mean operative time was 115 minutes (range 45 – 210 minutes). There were no deaths and no reoperations for complications. No port-site metastases occurred in patients with malignant lesions.

Conclusions : Laparoscopic liver resections, including major hepatectomies, are feasible and safe. Major and posterior resections are difficult though and conventional surgery remains an option.
