[Anatomy of splenic flexure and surgical treatment in 52 patients with non-obstructive splenic flexure colon cancer].
OBJECTIVE
To investigate the anatomic characteristics of splenic flexure, surgical techniques, and oncologic outcomes in 52 patients with non-obstructive splenic flexure colon cancer.


METHODS
Clinical data of 52 patients with non-obstructive splenic flexure colon cancer from March 2004 to March 2011 in the Department of General Surgery at the Henan Province Tumor Hospital were analyzed retrospectively.


RESULTS
There were 37 patients of regular type, 5 of mobile type, and 10 of adhesive type. All the patients received radical operation. Eighteen patients received pre-small intestine anastomosis, including 12 cases with regular type, 4 with mobile type, and 2 with adhesive type. The difference in pre-small intestine anastomosis among the three types was not statistically significant(P=0.062). In addition, 32 cases received retro-ileum anastomosis. There were no significant differences in operative time, intraoperative blood loss, number of lymph node dissection and positive lymph node, and postoperation complication rate among the three types. Follow up was available in all the cases. Five-year survival rates of cases with regular type, mobile type and adhesive type were 62.5%, 59.2% and 58.7% respectively(P>0.05).


CONCLUSIONS
Radical resection can provide satisfactory survival for splenic flexure colon cancer patients. The anatomy of splenic flexure does not affect the type of anastomosis. Retro-ileum anastomosis is a simple and effective method for reconstruction after radical resection of the tumor.
