Purpose: Surgical options previously described by us as part of a bowel management program for the treatment of soiling and fecal incontinence include (1) resection of a megarectosigmoid to reduce a patient's laxative requirement or (2) a Malone appendicostomy in patients who require enemas. We have found that some patients may benefit from both procedures.
Methods: We reviewed 18 fecally incontinent patients with structural or functional disorders of the anorectosigmoid (16 ARM, 1 spina bifida, and 1 SCT) who underwent both procedures.
Results: Of 18 patients, the enema regimen prior to resection had an average volume of 681 ml of saline (Range 400-1000 ml) and 60 ml (Range 48-117 ml) of additives (glycerine, castile soap and/or phosphate). Following the colon resection, the average volume of saline and additives was 335 ml (Range 130-650 ml) and 25 ml (Range 0-60 ml), respectively, a 50% reduction for both (P<0.01). The time for enema administration and evacuation was reduced by 25%, and the enemas were more effective, rendering the patients clean in 18 of 18 cases (follow-up was 3 months to 21 years). 2 patients later demonstrated that they could be managed with laxatives alone.
Conclusion: In patients with poor continence potential and a megarectosigmoid, combining a colon resection with a Malone appendicostomy can make the enema more effective. In some rare cases we found the resection may allow for a better response to laxatives.
