[Surgical treatment of chronic anal fissures. Modification of the operation of Gabriel (author's transl)].
The author reports a personal technique for treating chronic complicated anal fissures. The advantages of this technique are: 1. Complete removal of lesions (fissure and its sclerotic base). 2. Covering of the week area with good quality mucosa. 3. Small uncovered residual area with consequent fast healing. 4. Nonetheless good drainage of the suture line. 5. Sphincterotomy made unnecessary as the debridment close to the muscle of the posterior flap removes together with the fissure, the fibrous tract (pecten) that often formed beneath. 6. Horn-shaped incisions drain as well as the large excision of Gabriel and avoid development of a fibrous scar at the posterior anal commissure. 7. The operation is relatively painless. The experience of the author is based on 500 cases, with no morbidity or recurrence.
