Treatment of Fistula in Ano by Advancement Flap. Is It Outdated or Still Modern Approach?

Aim.Investigation of possibilities of magnetic resonance imaging as a whole, as well as different modes of MR scanning (without intravenous contrast, with intravenous contrast, with the use of diffusion-weighted imaging) in the diagnosis of cryptogenic fistulas of the rectum.Materials and methods. In the study were included 50 patients with cryptogenic fistulas of the rectum (21 women and 29 men). All patients underwent magnetic resonance imaging of the pelvic organs.Results.The sensitivity of MRI in the diagnosis of the primary fistulas was 100%. With regard to secondary fistulas MRI sensitivity was 91.7%, specificity was 94.3%. The sensitivity of MRI in the diagnosis of chronic abscesses paraproctitis was 82.6%, specificity was 95.2%. The sensitivity of the method in the visualization of internal opening was 95.5%, specificity was 80.0%. The sensitivity of the method in the diagnosis of external openings was 91.7% and specificity was 100%. In the analysis of separates MR scanning mode we didn’t find statistically significant differences between them (p < 0.05). Conclusions.Magnetic resonance imaging has a high diagnostic efficacy in the diagnosis of cryptogenic perianal fistulas. We didn’t find statistically significant differences between MR scanning modes.

PURPOSE. Examine the results of surgical treatment of fistulas of the anus and rectum. MATERIALS AND METHODS. Generalized material surgical treatment of 53 patients with different types of fistulas of the anus and rectum during the period 2010-2015. based coloproctological DRKTMU center. We used clinical, laboratory and instrumental methods of investigation according to generally accepted standards of coloproctology. RESULTS. We used an individualized approach, which, along with the known operations: seton, Gabriel-1, Gabriel-2, and used more modern methods of radical surgical procedures, taking into account «case» building the wall of the rectum: 1) muco-submucosal flap; 2) muco-muscular flap (consisting of mucosal and submucosal layers and inner circular smooth muscle layer of the gut). Methods of radical plastic surgery were performed in 39 (73,6%) patients with transsphincteral and extrasphincteral fistulas. Among them by the method of V.M.Maslyak (1990) - 18 (34,0 %) patients and mucosalflap according to the technique developed in the clinic - 21 (39.6%) patients. Patients satisfactorily suffered an intervention. In 4 (7,6 %) patients the disease recurred. Among them in 1 patient after 3 weeks and in 3 patients after 2-3 months after the intervention the recurrence of disease was detected. Of these in 2 (3,8 %) patients was detected transsphincteral fistulae and in 2 (3,8 %) -extrasphincteral rectumfistulas. Patients with recurrent fistulas were reoperated. CONCLUSION. The results indicate the feasibility of application in surgical proctology transanal plastic interventions with the movement of mucous-submucosal or mucosal-muscle flap from the known and improved our procedures.

AIM: to reveal fistula healing incidence after application of FiLaC™ technique and factors that can affect it. MATERIALS AND METHODS: when searching electronic medical databases for publications that evaluated the results of the FiLaC™ technique in the treatment of anal fistula, 6 studies were selected, corresponding to the search queries. The search was carried out taking into account the principles of systematic literature reviews and meta-analyses (PRISMA). The time interval for searching publications was between 2011 and October 2018. In the publications included in the analysis, the following parameters were evaluated: general characteristics of the study groups, technical aspects of the FiLaC™ technique, the site of the fistula in relation to the anal sphincter, the option of closing the internal fistula, the incidence of healing and recurrence of fistula, the duration of the follow-up period after surgery, re-operated cases of fistula recurrences. RESULTS: taking into account the data obtained in the analysis of the selected studies, the mean incidence of fistula healing was 64.5% (40.0-88.2)%. It was found that the only factors that can be used to assess their impact on the incidence of fistula healing were: the gender and the variant of the fistula site in relationship to the anal sphincter (transsphincteric/extrasphincteric). Statistical analysis and evaluation of the odds ratio revealed no effect on the treatment result of the above parameters. CONCLUSION: the analysis of the data showed that FiLaCis mainly indicated for the treatment of patients with extrasphincter and transsphincteric anal fistulas. The method can be recommended as a sphincter-sparing treatment in patients with initially weakened anal sphincter function and, consequently, with a high risk of anal sphincter insufficiency in the application of traditional techniques. Further evaluation of the treatment results in the treated period and their comparison with the results after other variants of coagulation of the fistula walls is required to obtain a clearer understanding of the effectiveness of the FiLAC technique.
