Abstract
BACKGROUND: After the failure of conservative therapy, the most effective surgical treatment for chronic anal fissures (CAFs) is lateral internal sphincterotomy. However, the choice of the procedure must be always evaluated carefully due to the risk of long-term anal continence impairment. The aim of the present study is to report the outcomes of fissurectomy with or without associated anoplasty.
METHODS: This study is a single-center retrospective study including patients with CAFs in whom conservative medical and non-medical treatments failed and who underwent fissurectomy with or without anoplasty from January 2015 to June 2023. Fecal continence, pain, and complications were assessed using specific questionnaires and scores.
RESULTS: Overall, 475 patients [280 males (58.9%)] with CAF underwent fissurectomy, with (n = 392; 82.5%) or without (n = 83; 17.5%) anoplasty. The majority of them (n = 379; 79.8%) had a posterior fissure. The mean follow-up was 49.9 months ± 26.13 months, with a minimum of 1 year, showing no intraoperative complications and a 4.2% postoperative complication rate. Missed healing occurred in 7.15% of patients at 6 months of follow-up, with higher recurrence and sphincterotomy rates in posterior fissures (p = 0.04). Cleveland Clinic Incontinence Scores were higher in patients who underwent anoplasty (p = 0.002). Interestingly, anoplasty led to a significant decrease in visual analogue scale (VAS) scores (p < 0.001), compared with those who did not undergo the procedure, with a consequent faster recovery.
CONCLUSION: Our study showed that fissurectomy, whether performed with or without anoplasty, was a highly effective surgical option for treating CAFs, achieving an overall success rate of 92.8% without significant impairment of continence and with a low complication rate. Further randomized prospective trials are needed to confirm this finding. Interestingly, fissurectomy with anoplasty seems to allow for better short-term outcomes in terms of postoperative pain and recovery time compared with fissurectomy alone.
