[Effects of splenic flexure and sigmoid colon variation on the types of anastomosis after left colectomy].

OBJECTIVE

To explore the effects of splenic flexure and sigmoid colon variation on anastomosis after left colectomy.

METHODS

The clinical data of 76 descending colon patients were collected retrospectively from March 2004 to April 2011 at our hospital. Statistical analysis was performed for the types of splenic flexure and sigmoid colon with regards to the choice of anastomosis.

RESULTS

There were mesenteric type (n = 55), mobile type (n = 7) and adhesive type (n = 14) for splenic flexure. And among 61 regular types, 15 were of variable type for sigmoid colon variation. There was significant difference of anastomosis between the types of sigmoid colon variation [43 (78.2%) vs 5 (71.4%) vs 9 (64.3%), P > 0.05] while no significant difference existed between the types of splenic flexure [I type 56(91.8%) vs II type 1 (14.3%), III or IV type 0, P < 0.05].

CONCLUSION

A clinician should pay more attention to the types of sigmoid colon variation. And it helps to select the right approach of anastomosis after left colectomy.
