EXPERIMENTALPatients were injected with 0·6 ml of a solution containing 30 units botulinum toxin A (Botox; Allergan, Ireland). A 27-G needle was used to give two injections of equal volume (0·3 ml) into the internal anal sphincter, one on each side of the anterior midline of the sphincter.

PLACEBO COMPARATORPatients in the placebo group received a 0·6-ml injection of saline. A27-G needle was used to give two injections of equal volume (0·3 ml) into the internal anal sphincter, one on each side of the anterior midline of the sphincter.
Interventions
Patients received a 0·6-ml injection of a solution containing 30 units botulinum toxin into the internal anal sphincter
Patients received a 0·6-ml injection of a saline solution into the internal anal sphincter
