Background: Anorectal malformations (ARMs) are major congenital malformations occurring in female children
in approximately 1 out of every 4000–5000 births. Posterior sagittal anorectoplasty (PSARP) was introduced for
their treatment in early 1980s by Pena and Devries. However, anterior sagittal anorectoplasty (ASARP) was first
introduced by Okada as a modification of the previous technique.
Purpose: The aim of this study was to report our experience and the long-term follow-up results of 594 female
patients with anorectal malformations treated by anterior sagittal anorectoplasty (ASARP) in a single center
over 22 years. We chose this approach as the incision is smaller, with minimal cutting of the external sphincter
and easier dissection of the vagina and rectum.
The type of our study was retrospective study.
Results: The study included 594 patients; 342 of them were less than 1 year old. About 526 patients had
rectovestibular fistula, anterior perineal anus in 55 patients, anocutaneous fistula in 6 patients and rectovaginal fis-
tula in 7 patients. All of these patients had been subjected to ASARP technique which had been done in one stage
without proceeding colostomy in about 470 cases and in staged fashion with a protective colostomy in 124 patients.
Postoperative follow up revealed that four patients (0.7%) developed anal retraction, 30 patients (5%) developed
anal stricture, 20 patients (3.4%) had rectal prolapse and 40 patients (6.7%) developed anterior anal migration.
Constipation was observed in 161 patients (27%) by the end of 1st postoperative year reduced to 41 patients (7%)
after one year. 474 patients were assessed for continence by Kelly's continence score and 453 patients showed
good result, 16 patients showed fair result and about 5 patients had poor continence outcome.
Conclusion: Anterior sagittal anorectoplasty is a procedure with optimal functional outcome especially at if done at
an early age in one stage without preliminary colostomy.

Anorectal malformations (ARMs) are major congenital malformations
in female children, occurring in approximately 1 out of every 4000–5000
births. On average, 70% of the female anorectal malformations are low,
17% are intermediate while 13% are high. Many procedures were used
for correction of these anomalies but their outcome was not satisfactory.
One of these procedures was the posterior sagittal anorectoplasty
(PSARP) which was introduced in the early 1980s by Pena and Devries
being done through a large incision extending to the coccyx dividing
the whole external sphincter complex [1].
Another procedure was described by Okada who described the an-
terior sagittal approach (ASARP) for correction of female anorectal
anomalies. This approach utilized the same basic principles as that of
the posterior one with a much smaller incision extending only to the
midpoint of the proposed new anus with only the anterior fibers of
external sphincter complex being divided. Also, the dissection of the
vagina and rectum, which is considered the most important step of
the operation, takes place under direct vision in ASARP [2].
The aim of this study was to report our experience and the long-term
follow-up results of female patients with anorectal malformations
treated by anterior sagittal anorectoplasty (ASARP) in a single center
over 22 years.
1. Patients and methods
Our retrospective study included 594 female patients with anorectal
anomalies admitted and operated on at our Pediatric Surgery
Department from March 1996 to March 2018. Patients with sacrospinal
anomalies were excluded from our study.
The patients' records were reviewed and the age at which the repair
was done, as well as the type of the anomaly (rectovestibular, anovestibular,
anterior perineal anus, rectovaginal fistula or anocutaneous fistula) was
recorded. All of the studied patients were treated by ASARP technique
either under cover of a proximal stoma (staged) or without a proximal
stoma (one stage).
