Colonic J pouch neo-rectum versus straight anastomosis for low rectal cancers.

AIM: The development of sphincter saving procedures for low carcinoma rectum has been the consequence of oncological and technological factors. The major disadvantage associated with these procedures is the development of anterior resection syndrome because of the resection of rectal reservoir. Colonic J pouch (CJP) neorectum has been practiced as an antidote to overcome this problem. We are working at a tertiary care center, which is a high volume center for rectal cancers. We thought it worthwhile to assess the efficacy of J Pouch neorectum viz.-a-viz. a straight coloanal anastomosis for low rectal cancers.

MATERIALS AND

METHODS

Hospital based prospective randomized study (June 2007-December 2009) low rectal cancers (4-12 cm from the anal verge). One group (20 patients) subjected to low/ultralow anterior resection with straight anastomosis (SA) and other group (22 patients) to CJP. The two groups were compared on the basis of functional outcome.

RESULTS

Anastomotic leak, strictures, frequency of bowel movements, nocturnal bowel movements, use of retarding medication and incontinence to solids, liquids and gases were seen more in SA group. All these findings were statistically significant.

CONCLUSIONS

We conclude that CJP has a significant functional advantage over SA and improves the overall quality-of-life in patients of low rectal cancers and the advantage persisted over a period of more than 30 months.
