Primary anorectoplasty in females with common anorectal malformations without colostomy.
OBJECTIVE
The objective of this study is to assess the feasibility of primary posterior sagittal anorectoplasty in vestibular fistula without a covering colostomy.


METHODS
Girls presenting from July 1997 to July 2005 with vestibular fistula were included prospectively in the study, in a nonrandomized manner, after excluding those with megarectosigmoid and pouch colon. All underwent primary posterior sagittal anorectoplasty after total gut irrigation with normal saline. They were kept nil per oral until the fifth postoperative day. No patient was started on anal dilatation. Patients were assessed for immediate and delayed complications as well as voluntary bowel movements and continence.


RESULTS
A total of 72 patients with an age range of 1.5 months to 8 years (median, 9 months) were studied after excluding 7 with pouch colon and 3 with megarectosigmoid. Of the 72, 3 had undergone previous surgery. Follow-up ranged from 7 months to 8 years. No wound dehiscence or recurrence of fistula was noted. There were 5 mild wound infections. At 1 month postoperative, all patients had 1 to 3 stools per day with no episodes of soiling. None required anal dilatations, laxatives, or enemas.


CONCLUSIONS
Primary posterior sagittal anorectoplasty in vestibular fistula can be performed without a covering colostomy provided fecal contamination of the wound can be kept to the minimum in the first postoperative week. We achieve this by thorough total gut irrigation preoperatively and keeping the child nil per oral for the first 5 postoperative days. Continence rates are excellent and postoperative constipation is unlikely if megarectosigmoid and pouch colon are ruled out before surgery. Anal dilatation is not required after surgery.
