What the experts said
Rectal prolapse is a very common problem following repair of an anorectal malformation
Rectal prolapse can cause mucous production and bleeding
Rectal prolapse can interfere with the patient's ability to close the anus and thereby affect bowel control
The anoplasty location should be checked with an electrical stimulator to confirm well-located positioning with circumferential contractions
Full thickness rectum is incised off the skin edge while preserving the sphincter muscle
Leaving the right side of the anoplasty untouched reduces the risk of postoperative stricture
The rectum is mobilized out until there is slight tension and the intended cut line will comfortably reach the anal skin
Extra stitches placed into the redundancy help straighten out the rectal tissue prior to incising it
The Lone Star retractor is very helpful to set up the anoplasty
The anoplasty technique involves taking a bite of anal skin to full thickness rectal wall
Dividing the upper and lower quadrants of the left-sided prolapse creates two triangles
All sutures are tied under slight tension so that once cut, the anoplasty retracts back nicely
