We describe a new therapeutic procedure for fissure-in-ano, endoscopic anal dilatation. Anal dilatation is performed with a two-valved anoscope under local anesthesia in an ambulatory setting. We report our results using this technique in 62 patients after a mean follow-up of 19 months (range: 12-24 months). Thirty days after the procedure, 55 patients (93%) were symptom-free, whereas 3 of them (4.8%) failed to improve. After nineteen months, one patient out of 47 in follow-up had a recurrence. No bleeding, discharge or defects of continence, either transient or permanent, were noted. The results of endoscopic anal dilatation are comparable with those of lateral sphincterotomy, can be achieved at a lower complication rate, with only minor and temporary complications, and performed by physicians with no specific surgical training.
