[Bowel control of elderly low rectal cancer patients after anus-retained operation].
OBJECTIVE
Though anus-retained operation has became the first choice in radical cure operation for rectal cancer, most surgeons whom fear of dissatisfied bowel control after operation recommend permanent bowel stoma in abdomen for elderly low rectal cancer patients rather than anus-retained operation. This study was to evaluate the bowel control of elderly low rectal cancer patients after anus-retained operation.


METHODS
A total of 80 elderly low rectal cancer patients were divided into > or =75-year old group (39 patients) and 60-74-year old group (41 patients). Clinical data and follow-up data of the 80 patients were analyzed; bowel function and continence of the 2 groups were compared.


RESULTS
The postoperative 18-month survival rate of all patients was 98.8%. The bowel control statuses of 76 patients were evaluable, of which 36 were in > or =75-year old group, 40 were in 60-74-year old group. Three months after operation, the bowel function was significantly poorer in > or =75-year old group than in 60-74-year old group (P<0.05), but the difference dissolved 6 months after operation (P>0.05). The time of recovering normal defecation frequency was slightly longer in > or =75-year old group than in 60-74-year old group (P>0.05). The prevalence of grade I incontinence 6 months after operation was significantly higher in > or =75-year old group than in 60-74-year old group (36.1% vs. 12.5%, P<0.05), but all symptoms of incontinence were relieved after treatment.


CONCLUSIONS
Most elderly low rectal cancer patients could maintain bowel control after anus-retained operation. Age alone should not be a contraindication to a restorative resection for low rectal cancer.
