Biofeedback with and without surgery for fecal incontinence improves maximum squeeze pressure, saline retention capacity and quality of life.
BACKGROUND
Fecal incontinence (FI) impairs quality of life. We performed an audit of biofeedback (BFB) in management of patients with FI.


METHODS
Fifty patients (median [range] age 30 [4-77] years; 28 men) who received BFB for median (range) of 15 weeks (4-28), either postoperatively (n=39), or as the sole treatment (n=11) were evaluated. Cleveland continence score (0-good, 20-poor), anorectal manometry parameters, and patient satisfaction (assessed by Fecal Incontinence Quality of Life Scale [FIQLS]) were evaluated at baseline and after the BFB therapy in all patients.


RESULTS
Continence scores improved after intervention. In the surgery + BFB group, mean (SD) continence scores baseline vs. postsurgery + BFB (post-treatment) were 18.2 (3.9) vs. 6 (5.9; p< 0.01). In the BFB alone group, scores were similar at baseline 11.7 (5.9) and 6.1 (5.2) post BFB (p=0.08). Maximum resting anal pressure (MRP) improved from preoperative 12.6 (9.8) mmHg to: vs. 21.1 (11.9) mmHg post-treatment (p< 0.01). In patients who received BFB alone, MRP did not change significantly (pre vs post BFB 22.9 (11.7) mmHg vs. 29.6 (12.1) mmHg [p=0.08]). Maximal squeeze pressure improved significantly (preoperative vs. post-treatment: 46.3 (41.2) mmHg vs. 78.3 (33.9) mmHg [p< 0.01]; pre vs. post BFB alone: 72.4 (34.8) mmHg vs. 114.5 (43.1) mmHg [p< 0.01]). In 29 patients (19 surgery + BFB; 10 BFB alone), maximal tolerable volume in saline continence improved from baseline 47.9 (27.4) mL to 152.6 (87) mL after surgery + BFB (p< 0.01); pre vs. post BFB: 98 mL (95.9) vs. 205 (134.3) p< 0.02]. There was significant improvement in all parameters of FIQLS in both groups: lifestyle (p< 0.02), coping/behavior (p< 0.02), depression/self perception (p< 0.02) and embarrassment (p< 0.02).


CONCLUSIONS
BFB therapy with or without surgical reconstruction of the damaged anal sphincter improves maximum squeeze pressure, saline retention capacity, quality of life and is a useful first line treatment for fecal incontinence.
