Abstract
Background and aims
Dynamic graciloplasty and artificial anal sphincter are two options for refractory incontinence, the efficacy of which was compared in a prospective study.
Patients and methods
Between November 1966 and June 1998, 16 patients were operated on (artificial anal sphincter 8, dynamic graciloplasty 8). Four consecutive operations with each technique were performed by two colorectal surgeons (one initiated the study with the neosphincter and the other with dynamic graciloplasty). Two independent observers assessed postoperative results at 4-month intervals. Patients were followed up to January 2001, with a median (interquartile range) of 44 (13) months and 39 (15) months for the nesophincter and the dynamic graciloplasty, respectively.
Results
Fourteen patients had complications. In the immediate postoperative period; there were eight cases of wound healing-related problems (four in the graciloplasty group). Perineal infection occurred in one patient in the graciloplasty group. At follow-up there were 11 complications (6 in the neosphincter group). Four patients undergoing neosphincter implantation had erosion or pain at the cuff site and had the implant removed (a new device was reimplanted in one). Four patients undergoing dynamic graciloplasty had the stimulator removed. Postoperatively the neosphincter was associated with a significantly lower score on the continence grading scale of the Cleveland Clinic Florida than graciloplasty.
Conclusion
The artificial anal sphincter is a more convenient technique than dynamic graciloplasty for institutions treating small number of patients. However, technical failures and complications during follow-up that require reoperation are very high in both types of treatments.
