Purpose: This study describes our clinical experience with adynamic bilateral gluteoplasty in 20 patients with total fecal incontinence, in whom a sphincter repair had failed (n = 17) or was nonviable.
Methods: Between 1986 and 1995, 12 women and 8 men ranging in age from 15 to 58 (mean, 37) years underwent different techniques of adynamic gluteoplasty. The indications for the operation were congenital anomalies, denervation, or sphincter destruction. Postoperative evaluation was clinical (Pescatori grading; self-evaluation) and manometric.
Results: Morbidity was only related to wound infection (n = 7) requiring late reoperations for neosphincter repair (n = 5), anal stenosis (n = 2), and incisional hernia after colostomy closure (n = 1). Two other patients with no complications also had further surgery for tightening of the neosphincter; they had a successful outcome. Of the 17 evaluable patients, 9 (53 percent) achieved normal control or were graded as Pescatori A-1, A-2, B-1, or C-1, 1 (6 percent) as Pescatori C-2, and 7 (41 percent) as Pescatori C-3. Six patients (35 percent) judged their results as excellent, three (18 percent) as good, one (6 percent) as fair, and seven (41 percent) as bad. Eight patients are able to retain 200 ml of water instilled into the rectum for between five minutes and two hours. For the nine patients with better results, the mean +/- standard deviation of the differences between postgluteoplasty and pregluteoplasty anal pressures were 40 +/- 25 mmHg (resting pressure) and 122 +/- 85 mmHg (squeeze pressure). These findings demonstrate a tonic and voluntary activity of the plasty. The author's technique has less morbidity, and excellent or good results were achieved in 67 percent of the patients. Failures were attributable to suture disruption (n = 4), poor muscular contraction (n = 2), and intractable constipation (n = 1).
Conclusions: Adynamic gluteoplasty is efficient for achieving good or very good continence status in a higher proportion of patients than with other adynamic muscle transfer procedures.
