Restoration of Fecal Continence After Functional Gluteoplasty

Abstract

For patients with severe fecal incontinence, reconstruction of the anal sphincter, via gluteoplasty, may improve quality of life, but little is known about long-term functional results. We present our comprehensive experience with gluteoplasty, highlighting technical refinements, donor-site morbidity, and functional outcomes. We performed a retrospective analysis of 25 consecutive patients (22 female, 3 male; mean age 42 years, range 23-65) undergoing gluteoplasty for fecal incontinence at a university teaching hospital from 1996-2004. Etiology of incontinence was as follows: obstetrical injury (n = 13), irritable bowel syndrome (n = 3), previous rectal surgery (n = 3), Crohn disease (n = 3), impalement (n = 1), rectocele (n = 1), and idiopathic (n = 1). Gluteoplasty was successful in restoring fecal continence in 18 patients (72%) and was partially successful in 4 patients (16%). Two patients required permanent ostomy because of refractory incontinence. Donor-site morbidity and perirectal complications were observed in 16 patients (64%) and included dysthesias (n = 7), cellulitis (n = 5), irregular contour (n = 3), abscess (n = 2), seroma (n = 2), fistula (n = 1), but no hip dysfunction or altered gait. Mean length of follow-up was 20.6 months (range: 3-68 months). Despite a high incidence of donor-site and perirectal complications, unilateral functional gluteoplasty was successful in restoring long-term fecal continence in most patients.
