Abstract

Background: There is scant data regarding the outcomes of hand-assisted laparoscopic surgery (HALS) for colorectal liver metastasis (CRLM). The aim of this study is to report our experience and analyze the short-term and long-term results.

Materials and methods: Retrospective study of patients undergoing HALS for CRLM in 2 university affiliated medical centers.

Results: Two hundred and thirty-eight liver procedures were performed on 145 patients including 205 parenchymal sparing resections and 33 anatomic resections. The median number of metastases was 1 (range: 1 to 8), 38 patients (26.2%) had 3 or more metastases, and 41 patients (28.3 had a bi-lobar disease. The tumor size was 20 (2 to 90) mm, and 52 patients (36.6%) had a tumor larger than 30 mm. Nighty-nine patients (67.8%) received neoadjuvant chemotherapy. In 8 patients (5.5%) the laparoscopic liver resection was combined with ablation, and 16 patients (11%) underwent a synchronous resection of colorectal cancer. The median operative time, blood loss during surgery, and postoperative hospital stay were 163 minutes, 300 mL, and 4 days, respectively. The median modified Iwate complexity score was 4 (0 to 10) and the conversion rate to open surgery was 5.5%. The overall and major complication rates were 23.8% and 3.6%, respectively. The mortality rate was 0.7%. R0 resections were achieved in 91% of patients. Median overall survival for all the cohort (intend to treat) was 59 months, and the 8- and 10-year overall survival rates were 47.3% and 24.9%, respectively.

Conclusions: This study shows that HALS is a safe and efficacious treatment for selected patients with CRLM.
