Continent appendicostomy in the treatment of fecal incontinence.

BACKGROUND

Fecal incontinence is common in children with anorectal anomalies or spina bifida. If it is possible to achieve fecal control, patients are given a large volume of enema once a day. Retrograde enemas are often unpleasant in children, particularly in adolescents. Malone procedure of antegrade appendicostomy achieves antegrade colonic irrigation.

MATERIAL AND

METHODS

From 1996 to 2003 Malone antegrade appendicostomy was performed in 10 patients with fecal incontinence. The patients were aged from 5 to 24 years. In 4 patients fecal incontinence was due to an anorectal anomaly, and in 6 patients spina bifida. Preoperatively, all patients were given a clysma to control fecal incontinence. The patients, who remained clean with regular usage of the clysma for 24 hours or longer, fulfilled the criterion for the formation of continent appendicostomy. In 9 patients the cecal appendix was used to create a stoma, while in another one a lateral tubularized cecal flap was applied. In 3 patients a continent conduit was also done due to urinary incontinence. The follow-up period was from 1 to 8 years. A patient was reoperated due to stenosis of the stomal aperture, while another one has not been using the stoma because of social reasons.

CONCLUSION

Continent appendicostomy is a simple surgery, which is effective in the control of fecal incontinence in most children. It is indicated only in patients in whom the rerograde clysma successfully cleans the colon and if patient and parents are motivated to use it. Possible complications, among which stenosis is the most frequent, can be solved with a reoperation.
