Effectiveness of modified fistuloscopy in complex and recurrent anal fistula

The objective of the paper is to develop and implement a modified fistuloscopy method for minimally invasive treatment of anal fistulas. Materials and Methods. Thirty-one patients with chronic paraproctitis underwent special treatment. Depending on the type of fistula, patients were divided into 4 groups: 19 persons with transphincteric fistulas (61.3 %), 5 patients with extrasphincteric fistulas, grade 1 (12.9 %), 3 patients with extrasphincteric fistulas, grade 2 (9.7 %), and 4 patients with extrasphincteric fistulas, grade 3 (16.1 %). All fistulas were recurrent. We used an original method for anal fistula treatment for the patients of the main group (RF patent application No. 2017144148/14 (075775). A patient is lying on the operating table on his back, lower limbs raised. The surgical area is treated with antiseptic agents; then a rigid fistuloscope is put into the fistula external opening under anesthesia. At the end of the operation the fibrin glue BioGlue is injected into the fistula residual cavity through the external opening until it is completely filled...
