The effect of abdominal ventral rectopexy on faecal incontinence and constipation in patients with internal intra-anal rectal intussusception

Aim Optimal treatment of anal incontinence in a patients with a normal anal sphincter is controversial, as is the role of intra-anal rectal intussusception in anal incontinence. We evaluated the results of abdominal ventral rectopexy on anal continence in such patients. Method Forty consecutive patients with incontinence and intra-anal rectal intussusception without a sphincter defect were treated by abdominal ventral mesh rectopexy without sigmoidectomy. The Cleveland Clinic Incontinence Score (CCIS), patient satisfaction and constipation before and after surgery and recurrence were recorded. Results The mean CCI scores were 13.2 (=/-4.25) preoperatively and 3 (+/- 3.44) postoperatively (P<0.0001). Patient assessment was reported as 'cured' in 26 (65%), 'improved' in 13 (32.5%) and 'unchanged' in one (2.5%) patient. Constipation was induced in two (5%) patients and was cured in 13 of 20 (65%) patients who were constipated before surgery. One case of recurrent prolapse occurred after a mean follow-up of 38 months. Conclusion Intra-anal rectal intussusception may be associated with anal incontinence. For these patients, abdominal ventral mesh rectopexy appears to be an adequate treatment.
