Procedures for treating rectal prolapse may constitute some of the best applications for colorectal laparoscopic techniques. Although the condition is benign, rectal prolapse is often debilitating and frequently progressive in terms of functional limitations. Moreover, many patients are elderly, medically unfit, or both. A technique that afforded relief of prolapse and of incontinence by laparoscopic rectal sacropexy, performed without sutures, using a newly designed laparoscopic sacral tacker and laparoscopic staples, is described. Indications, contraindications, technical details, and surgical implications are discussed. Laparoscopic pelvic suspension procedures are presented as realistic and appropriate objectives for colon and rectal surgeons.

Topical administration of a phosphodiesterase-5 inhibitor (sildenafil, Viagra) significantly reduces anal sphincter pressure in patients with chronic anal fissure. A beneficial effect of nitric oxide on the spastic anal sphincter has been demonstrated previously. This study confirms that this effect need not be derived solely from nitric oxide donors. New therapeutic avenues for treatment of anal fissure through indirect enhancement of nitric oxide activity are suggested.

Transanal flap-advancement procedures for complicated anorectal or rectovaginal fistula may include vertically incised flaps, horizontal flaps, and tubal flaps. Anatomic and pathologic considerations affecting choice of the three major techniques are examined in the context of their historical development over the last century. Application of the tubal (or sleeve) advancement principle is described in a woman whose combined rectovaginal and cryptogenic fistulas encompassed more than one-third of her anal circumference, necessitating surgical modifications beyond those afforded by previously documented techniques. Obliteration of disease and preservation of sphincteric competence were the achieved objectives of the procedure. Rationale for the procedure and technical details of the sleeve advancement anorectoplasty are described, mindful of the surgical antecedents of this therapeutic option.
