Core Tip
Core tip: Pelvic floor biofeedback was accepted to be an effective therapy for anismus. However, unfortunately the treatment proved to be ineffective in some cases. In our study, we performed biofeedback training combined with botulinum toxin type A injection to the puborectalis and external sphincter. Diagnosis was made by anorectal manometry, balloon expulsion test, surface electromyography of the pelvic floor muscle, and defecography. Follow-up was conducted before the paper was written. Improvement was evaluated using the chronic constipation scoring system. Botulinum toxin type A injection combined with pelvic floor biofeedback training achieved success in 24 (24/31) patients, with 23 maintaining persistent satisfaction during a mean period of 8.4 mo.
