A Prospective Evaluation of the Strattice-LIFT to Treat Anal Fistula

2015-04-28 14:38:22 | BioPortfolio


This clinical trial will evaluate the safety and efficacy of the Strattice-LIFT procedure to treat anal fistulas.


The treatment of anal fistulas remains a challenging clinical problem. Fistulotomy is highly effective, but carries a significant risk of postoperative incontinence. A variety of surgical procedures that do not divide the sphincter muscle may be offered to patients, however none of them are as effective as fistulotomy.

The LIFT (ligation of intersphincteric fistula tract) procedure is a newer option for the treatment of transsphincteric fistulas. Initial results have been promising. However, some fistulas recur after the LIFT procedure because the divided ends of the fistula tract recanalize. Insertion of a barrier into the intersphincteric space may prevent this process. Strattice is acellular porcine dermis, will be used for this purpose.

This prospective trial will evaluate the safety and efficacy of the Strattice-LIFT procedure for the treatment of transsphincteric anal fistulas.

Medical and Biotech [MESH] Definitions

An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).

An abnormal anatomical passage that connects the VAGINA to other organs, such as the bladder (VESICOVAGINAL FISTULA) or the rectum (RECTOVAGINAL FISTULA).

A fistula between the maxillary sinus and the oral cavity.

Tumors or cancer of the anal gland.

Protrusion of the rectal mucous membrane through the anus. There are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.
