Efficacy of anorectal biofeedback in scleroderma patients with fecal incontinence: a case–control study

Objective: To determine whether anorectal biofeedback therapy can improve the symptoms of fecal incontinence (FI) in patients with scleroderma when compared to patients with functional FI, and also whether there is any effect on anorectal physiology or quality of life (QOL). FI in patients with scleroderma is highly prevalent and is associated with significant loss of QOL. Biofeedback has been proven to be an effective treatment for functional FI, but there are no data to support its use in scleroderma.

Materials and methods: 13 consecutive female patients (median age 59, IQR 47–65 years) with scleroderma, and 26 age- and parity-matched female patients with functional FI (disease controls, 2:1), underwent biofeedback therapy for management of FI. Fecal incontinence severity index (FISI), anorectal physiology, feeling of control and QOL were collected before and after 6 weeks of biofeedback therapy, with additional scoring repeated at 6-month follow-up.

Results: After biofeedback treatment FISI, feeling of control and QOL significantly improved in both groups (p?p?Conclusions: Patients with scleroderma benefit from biofeedback therapy to the same extent as that achieved in patients with functional FI. There are significant improvements in symptoms, physiology and QOL. Biofeedback is an effective, low-risk treatment option in this patient group.
