[Surgical treatment of rectovaginal fistula with vaginal rectangular flap]. / Khirurgicheskoe lechenie rektovaginal'nykh svishchei rasshcheplennym vlagalishchno-pryamokishechnym loskutom.

OBJECTIVE: To evaluate the early and long-term outcomes of rectovaginal fistula closure with vaginal rectangular flap. MATERIAL AND METHODS: There were 61 patients with rectovaginal fistula for the period 2012-2020. Median age of patients was 35 years [31; 48]. Postpartum fictula was observed in 27 (44.2%) cases, postoperative - 10 (16.4%) patients, inflammatory - 15 (24.6%) patients, other causes - 9 (14.8%) patients. Disease recurrence occurred in 29 (47.5%) patients. RESULTS: Median follow-up period was 36.2 [6; 64] months. Postoperative recurrence of rectovaginal fistula occurred in 19 (31.1%) patients. Length of hospital-stay ranged from 3 to 36 days (median 14 [12; 16]). We analyzed the relationship between the risk of disease recurrence and various factors, including etiology of rectovaginal fistula, localization and diameter of the fistula, intraoperative cautery, previous surgeries and preventive colostomy. CONCLUSION: Vaginal rectangular flap is effective for rectovaginal fistula. Multivariate analysis confirmed two significant risk factors of postoperative recurrence: diameter of fistula over 5 mm and its localization in the rectum above the upper border of surgical anal canal (more than 7 mm from the dentate line).

[Comparison of Doppler-assisted dearterialization with mucopexy and hemorrhoidectomy].

AIM: To compare two methods of hemorrhoid treatment. MATERIAL AND METHODS: This prospective study included 240 patients with hemorrhoids stage III-IVA. Stages III and IVA were diagnosed in 156 (65%) and 84 (35%) patients respectively. Randomization was performed using envelopes method in one to one distribution. In group 1 (n=120) Doppler-assisted dearterialization of internal hemorrhoids with mucopexy was performed (DDM), in group 2 (n=120) - hemorrhoidectomy using harmonic scalpel (HE). RESULTS: Duration of surgery was 17.9±6.1 and 34.5±10.1 minutes in DDM and HE groups respectively (p<0.01). Postoperative pain severity was higher in group 2 (4.8 compared with 2.5 scores of the first group (p<0.01). Narcotic analgesics were used less often in DDM group (1.3 doses compared with 6.1 doses in HE group (p<0.01). Disability period was 14.4±5.2 and 30.3±5.4 days in both groups respectively (p<0.01). Immediate postoperative complications occurred in 9 (7.5%) and 19 (15.8%) patients of DDM and HE groups respectively. Recurrent prolapse of internal hemorrhoids was diagnosed in 2 (1.7%) patients of the 1st group in terms of up to 45 days. CONCLUSION: DDM is reliable minimally invasive method of hemorrhoids stage III-IVA treatment and has similar efficacy with HE. DDM reduces postoperative pain severity, hospital stay and disability period.

NORMAL MEASUREMENTS OF PRESSURE IN ANAL CANAL DURING SPHINCTEROMETRY ON S4402 MSM AND WMP SOLAR GI DEVICES.

AIM: To assess normal measurements of pressure in anal canal during sphincterometry on S4402 MSM and WPM Solar GI devices. MATERIALS AND METHODS: The study included 126 patients with colonic polyps. inclusion criteria were absence of anal incon- tinence and defecation disorders. Seventy-three patients were assessed with S4402 MSM device, Included were 28 males (mean age 56,2±10,2 years) and 45 females (mean age 54,9±13,7 years). Fifty-three subjects were assessed via WPM Solar GI device: 23 women (mean age 51,4±11,1 years) and 30 males (mean age 65,1±15,9 years). RESULTS: Sphincterometry results using S4402 MSM device in males were as follows: mean resting pressure - 52,1+198 mm Hg; maximal resting pressure - 60,3±21,9mm Hg; mean pressure at voluntary contraction - 118,2±41,5 mm Hg and maximal pressure at voluntary contraction - 174,2±56,8 mm Hg. Corresponding values in females were 37,1±15,3 mm Hg, 43,8±15,5 mm Hg; 75,1±29,5 mm Hg and 99,1±39,7 mm Hg, respectively. Using WPM Solar GI sphincterometry the following figures were obtained in males: resting pressure - 43-61 mm Hg; maximal voluntary contraction pressure - 121-227 mm Hg; mean pressure - 106-190 mm Hg; maximal pressure with coughing test - 45-175 mm Hg; at straining minimal pressure decreased to 19-43 mm Hg (20-60%). In females the results were as follows: resting pressure - 41-63 mm Hg; maximal pressure at voluntary contraction 110-178 mm Hg; mean pressure - 88-146 mm Hg; maximal pressure at coughing test - 76-126 mm Hg, pressure decrease at straining to 28-52 mm Hg, relaxation up to 19-40%.
