Splenic flexure colon cancers: minimally invasive treatment.

Abstract

Optimal treatment of splenic flexure (SF) colon cancer-less than 10% of all colorectal cancers is a matter of debate, in particular with regard to the optimal extent of radical surgery, according to the oncological principles of curative resection. Aims of this study were to assess the clinicopathological characteristics and report operative data and survival of patients with SF colon cancers. Short- and mid-term outcome of patients undergoing laparoscopic curative resection for SF colon cancer between June 2005 and September 2011 was assessed. The analysis considered 16 patients: 10 underwent segmental resection, 4 left hemicolectomy and 2 subtotal colectomy. There were no intraoperative deaths or major morbidity. The median operative time was 185 min. The median number of lymph nodes harvested was 17. Disease-free survival rate at 30-month follow-up was 75%. Laparoscopic resection of SF cancer is feasible and safe. Oncological principles of disease-free margins and minimum node harvest can be respected even with segmental resection.
