Abstract/OtherAbstract:
INTRODUCTION: Anal fissure is associated with anal pain and bleeding. Lateral internal sphincterotomy (LIS) has been a common form of surgical management. This can however cause incontinence and hence an equally effective alternative without this risk would be ideal. Anal fissurectomy and an anal advancement flap (AAF) have been used as an alternative to LIS. METHODS: We carried out a retrospective analysis of the results of AAF and LIS for the treatment of anal fissure. Fifty patients underwent AAF and a further 50 cases were chosen who had undergone LIS over the same time period. Patient and procedural data were collected including post-operative course. RESULTS: Presenting symptoms included anal pain (94%), rectal bleeding (77%) and constipation (15%). Mean (±SD) follow-up was 20 ± 12 months in the AAF group vs 22 ± 12.5 months in the LIS group. Healing of fissure was achieved in 96% of patients after AAF and 88% after LIS (p = 0.27). Resolution of symptoms was achieved in 90% after AAF and 72% of patients after LIS (p = 0.04). LIS was associated with an increased incidence of readmission with infection and pain (8% vs 4%, p = 0.35). Seven patients whom had undergone successful AAF with complete resolution of symptoms had previously had LIS with failure of symptom relief. There was no incidence of faecal incontinence in either group. CONCLUSION: AAF is associated with a higher incidence of symptomatic relief and fissure healing and lower incidence of complications when compared with LIS. AAF is effective at healing fissures which are refractory to LIS.
