Laparoscopic resection of hepatic colorectal metastases

Abstract

Background Liver resection for secondary malignancy has become the standard of care in appropriately staged patients, offering 5‐year survival rates of >40%. Reports of laparoscopic liver resection have been published with increasing frequency over the last few years. In these small series approximately one‐third of all operations have been for malignancy, but survival figures cannot be assessed yet. Methods A retrospective review of all laparoscopic liver resections performed by four surgeons in Brisbane between 1997 and 2004 was done. Follow‐up was by regular patient review and telephone confirmation. Results Of 84 laparoscopic liver resections, 33 (39%) were for malignancy; 28 of these were for metastases (22 colorectal). Thirteen patients had left lateral sectionectomy with minimal morbidity; nine right hepatectomies were attempted and six cases of segmental or subsegmental resection were performed. Survival rates in 12 patients followed for 2 years with colorectal secondaries were 75% with 67% disease‐free. Discussion Laparoscopic liver resection is feasible in highly selected cases of malignant disease. Patients need to be appropriately staged and surgeons need a broad experience of open liver surgery and advanced laparoscopic procedures.
