Gaining Rectal Length During Posterior Sagittal Anoplasty / PSARP
Colorectal Center surgeons at Cincinnati Children's Hospital Medical Center provides information about gaining rectal length in Posterior Sagittal Anoplasty / PSARP.
Enough rectal length must then be gained in order to perform a comfortable, tension-free anastomosis between the rectum and the skin.
As traction is exerted on the mucosal stitches plus the stitches we previously placed in the rectal edge during the opening of the rectum, some grooves can be seen which demonstrate the tension lines that hold the rectum.
Those bands must be divided in order to gain rectal length and they are divided in a circumferential manner.
Histologic study of the bands demonstrates that they are mainly vessels and nerves; the vessels are found more prominently in the lateral aspects of the rectum (hemorrhoidal vessels).
It is important not to dissect in excess, but just as much as is necessary to achieve the goal of suturing the rectum to the skin with a moderate amount of tension, which will help to prevent rectal prolapse.
