Background
Redo surgery for anorectal anomalies (ARA) may be considered a special category of reconstructive surgery with less predictable outcomes. In this report, we studied anatomical derangements in a group of boys following a previously complicated PSARP procedure, in addition to the effect of reoperation on rectifying this distorted anatomy.
Results
The study included 27 boys who were re-operated after a previous complicated PSARP. Included cases were divided into two groups: group A (14 cases) was referred before colostomy closure with an obviously complicated primary operation, and group B (13 cases) was referred with delayed complications after colostomy closure.
Conclusion
A wide pelvic hiatus was a frequently encountered postsurgical complication after failed PSARP that has most probably resulted from poor reconstruction of the pelvic floor at time of the primary repair. Re-approximation of the split halves of levator ani in the midline behind the anorectum at reoperation can help to correct the distorted internal anatomy and improve bowel control in these cases.
