BACKGROUND: Botulinum toxin injection into the internal anal sphincter (IAS) is gaining popularity as a second line therapy for chronic anal fissures after patients fail medical therapy. The dosage of Botulinum toxin reported in the literature ranged from 20 to 50 IU. Complicated chronic anal fissure is defined as persistent fissure concurrent with other perianal pathology. We report a new approach involving high-dose circumferential chemodenervation (HDCC) of 100 IU in treating these complicated chronic anal fissures.
AIM: The aim of this study was to evaluate the fissure healing, complication, and recurrence rates with HDCC.
METHODS: Complicated anal fissure was defined as fissure with other perianal pathologies including skin tag, hypertrophied papilla, fistula, symptomatic hemorrhoids, anal condylomata, and abscess. Between 2008 and 2012, 62 consecutive patients (28 Blacks, 33 Whites, 1 Hispanic) with complete follow-up data were included in this single arm study. These patients underwent HDCC-IAS with addition interventions by a single colorectal surgeon. Follow up data were obtained by chart review and office follow up.
RESULTS: Of the 62 patients, the overall success rate was greater than 70% at 3 months follow-up. A few patients developed transient flatus or fecal incontinence, but shortly resolved. There was no major complication following HDCC-IAS.
CONCLUSIONS: Combination therapy involving HDCC-IAS and local anorectal surgery for associated condition is both safe and effective for fissure healing.
