Anterior sagittal anorectoplasty: An alternative to posterior approach in management of congenital vestibular fistula.

BACKGROUND

Better exposure, possibility of extension if needed and precise placement of the anal canal within the external sphincter complex have made the posterior and anterior sagittal approaches more popular and established for the correction of anovestibular fistula. The mini posterior sagittal anorectoplasty (PSARP) was the procedure of choice for female ARM at our center till date. As an alternative surgical option, we performed anterior sagittal anorectoplasty (ASARP) in 15 cases of anovestibular fistula and compared them with 12 cases of vestibular fistula operated by PSARP technique.

PATIENTS AND

METHODS

Fifteen female infants with vestibular fistula who had anterior sagittal anorectoplasty (ASARP) procedure were reviewed. The procedure and its outcome were evaluated.

RESULTS

The manoeuvering during anesthesia and operative access were quite easier in ASARP compared to PSARP. Delineation of plane in ASARP between rectum and vagina was easier and clearer in comparison to PSARP. Rent occurred in the posterior vaginal wall in three cases of ASARP and two cases of PSARP. There were two cases of wound infection in each group. Three cases of PSARP group developed anal stenosis and constipation while one in the ASARP group developed constipation.

CONCLUSION

Anesthesia and access in ASARP makes it an easier alternative option to PSARP in the management of anovestibular fistula in girls.
