Answer

The clinical and cost benefits of routine preoperative anal manometry, pudendal nerve motor latency, and colonic transit are unclear. Anal manometry shows low resting pressure; patients with coexisting fecal incontinence also have low squeezing pressures. However, after surgery, the resting pressure or sphincter length may not change or improve. Squeeze pressure may improve. [31]
