Background
We compare lateral internal sphincterotomy as an effective treatment of chronic fissure in ano to fissurectomy, which is as an alternative surgical treatment.
Methods
Sixty two consecutive patients were divided into two groups through sequential sampling. Thirty patients underwent fissurectomy and 32 underwent lateral internal sphincterotomy. After a median follow-up of 22 months, we compared the results of the two procedures. In addition to frequent visits on a predetermined basis, a telephone inquiry into fissure recurrence and continence status was made.
Results
All patients in both groups were pain-free and without bleeding within 1 week. In both groups, urinary retention was noted in one patient. Incontinence to flatus was noted in the fissurectomy (F) group in two (6.2%) patients, but no incontinence was noted in the lateral internal sphincterotomy (LIS) group. There was one patient (3.1%) with fissure recurrence in the F group but none in the LIS group. No patient in either group was afflicted with anal stenosis or perianal infections. All wounds healed within 8 weeks. Twenty nine patients (96.6%) in the LIS group and 28 (87.5%) in the F group reported satisfactory results with their procedure.
Conclusion
In the surgical treatment of chronic anal fissure not responding to conservative management, LIS may be the better treatment and, perhaps, the preferable surgical technique with fewer total complications (P < 0.005).
