Aim:
The aim of this study was to evaluate the safety and feasibility of single-port laparoscopic multivisceral resection (SLMVR) for locally advanced colon cancer invading or adhering to neighboring organs.
Method:
A prospectively collected database was collated of all patients undergoing SLMVR from January 2011 to December 2014. Short-term and long-term oncologic outcomes were evaluated.
Results:
Thirty consecutive patients who underwent SLMVR were identified and the completion rate was 90%. The R0 resection rate of the primary tumor was 100%. The postoperative complication rate was 23.3%. The 3-year relapse-free survival rates of patients with stage II (n=11) and stage III (n=12) disease were 80.8% and 54.6%, respectively. The 5-year overall survival rates of patients with stage II and stage III disease were 75.8% and 75.0% over a median follow-up of 42 months, respectively.
Conclusions:
SLMVR for locally advanced colon cancer is safe and feasible in selected patients.
