Restorative proctocolectomy. Clinical results and manometric findings with long and short rectal cuffs.
Clinical results and manometric findings were compared in 82 patients following restorative proctocolectomy. There were 41 patients with long rectal cuffs measuring 8 to 10 cm. There were 39 J-shaped pouches and 2 S-shaped pouches in this group. Forty-one patients had short rectal cuffs measuring 2 to 3 cm. There were 28 J-shaped pouches and 13 S-shaped pouches in this group. Anal manometry was performed in ten patients with long rectal cuffs and in ten patients with short rectal cuffs matched for age, sex, and stool frequency. Postoperative complications were significantly greater in patients with long rectal cuffs. Functional results and manometric findings were similar. No patient demonstrated a normal rectoanal inhibitory reflex. The data in this study suggest that a short rectal cuff can be used safely for restorative proctocolectomy with satisfactory results. A normal rectoanal inhibitory reflex may be absent after restorative proctocolectomy, and this does not interfere with the attainment of continence.
