Background and Aims: In this decade, laparoscopy-assisted hepatectomy has been rapidly spreading because of its less-invasiveness. Because metastatic liver tumor and hepatocellular carcinoma (HCC) often need repeated operation, minimally-invasive laparoscopy-assisted hepatectomy have a number of advantages to keep the damage and the period for subsequent therapy at a minimum. Herein we present our experiences of laparoscopy-assisted hepatectomy for the treatment of metastatic liver tumor and HCC and evaluate its usefulness.
Methods: We retrospectively analyzed the clinical outcomes of 41 patients who had undergone laparoscopy-assisted hepatic resection for metastatic liver tumor and HCC from January 2006 to March 2011 at Eiju General Hospital. We adopted laparoscopy-assisted hepatectomy appropriately, in consideration of adhesion due to surgery for primary disease or incision for simultaneous resection of primary disease.
Results: Twenty three and 18 laparoscopy-assisted hepatectomy for treatment of metastatic liver tumor and HCC were carried out. Metastatic liver tumors included 15 metastases of colon cancer, 1 metastasis of ovarian carcinoma, 1 metastasis of gastrointestinal stromal tumor of jejunum, 1 metastasis of breast cancer. The patients were composed of 25 men and 16 women. The patients’ mean age was 67.7 ± 9.9 years. Tumor mean size was 3.7 cm (range: 1.0 cm to 10 cm). There were 21 partial hepatectomy, 3 lateral sectionectomy, 3 anterior sectionectomy, 3 posterior sectionectomy, 2 left hepatectomy and 9 right hepatectomy. The operation consisted of laparoscopic mobilization of the target liver lobe, followed by open liver resection through a 8-12 cm extraction site. The mean operative time was 390 ± 124 minutes and 3 patient had blood transfusion. There were no intraoperative complications and no conversion to conventional open method. Mean postoperative hospital stay was 16 ± 13 days. There were no critical postoperative complications which need intensive therapy and no postoperative mortality.
Conclusion: Our experiences indicated that laparoscopy-assisted hepatectomy was a safe and useful option in the treatment of metastatic liver tumor and HCC. More accumulation of data may be needed for evaluation of long-term outcome.
