Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The main cause of the development of a chronic anal fissure is a spasm of the internal sphincter. It should be eliminated first of all to ensure effective therapy. All the main treatment methods, such as medicinal relaxation of the internal sphincter with 0.4% nitroglycerin ointment, lateral subcutaneous sphincterotomy, and pneumodivulsion of the anal sphincter are aimed at its removal. However, the optimal method has not yet been developed. Non-surgical treatments are often attended by relapse of disease, while surgical treatment is often complicated by intestinal contents incontinence, usually gas and loose or hard stool in some occasions (grade 3 anal sphincter insufficiency). In particular, lateral subcutaneous sphincterotomy performed in such patients is associated with an increase in the degree of anal incontinence in the early postoperative period.
Botulinum Toxin Type A application in treatment of patients with chronic anal fissure (after fissure excision) is intended to improve the therapy results, namely to reduce the frequency and duration of anal sphincter insufficiency after sphincter spasm removal (reduction in the number of patients suffering from post-operative incontinence)

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
main group
Patients of the main group undergo excision of the anal fissure with further relaxation of the internal sphincter with botulinum toxin A (40 units, injection into the internal anal sphincter at 1, 5, 7 and 11 hours, 10 units each)
excision of the anal fissure with further relaxation of the internal sphincter with botulinum toxin A
patients undergo excision of the fissure in combination with drug relaxation of the internal sphincter with botulinum toxin type A at a dosage of 40 units of action; an additional injection of platelet-rich plasma is added
control group
Patients in the control group undergo excision of the anal fissure with further relaxation of the internal sphincter with botulinum toxin A (40 units, injection into the internal anal sphincter at 1, 5, 7 and 11 hours, 10 units each)
excision of the anal fissure with further relaxation of the internal sphincter with botulinum toxin A
patients undergo excision of the fissure in combination with drug relaxation of the internal sphincter with botulinum toxin type A at a dosage of 40 units of action; an additional injection of platelet-rich plasma is added
