A comparison between Marlex and resection rectopexy

The role of sphincter recovery, and postoperative constipation in the recovery of continence after both anterior and posterior Marlex rectopexy (APR) and resection and rectopexy (RR) has been investigated. Neither bowel frequency or straining at stool, nor incomplete emptying is significantly altered in either group although emptying is improved overall. Upper anal canal electrosensitivity is reduced postoperatively (APR 18 mA preoperatively vs. 13 postoperatively [n.s.], RR 15 vs. 13) as is the volume for appreciation of rectal filling (APR 77.5 ml preoperatively vs. 50 postoperatively, RR 55 ml vs 32.5).

Continence postoperatively does not directly depend on sphincter recovery or postoperative constipation. Improved anorectal sensation may be an important factor in postoperative improvement.
