- Brief Summary
Aim: To assess the efficiency of the micro-flavonoid fraction (MMF) administration prior to anorectal surgery with spinal anesthesia on postoperative pain severity reduction.
Methods: Patients who meet the following criteria are included: participants must be diagnosed with surgical treatment of anorectal diseases. All participants are randomly divided into 2 groups: the first one gets a tablet with 1000 mg MFF (Detralex®), the second one gets a tablet containing starch per os 14 days before surgery (72 participants per arm). Then patients of each group will continue MFF administration for 30 days after surgery. Patients of both arms receive spinal anesthesia and undergo surgery. Following the procedure the primary and secondary outcomes are evaluated: frequency of the opioid drugs intake, the severity of the postoperative pain syndrome, duration and frequency of other drugs intake, readmission rate, overall quality of life, time from the procedure to returning to work and the complications rate, C-reactive protein level.
Discussion: the MFF intake allows reducing the severity of the hemorrhoidal disease symptoms during conservative treatment. In addition, the Detralex® efficacy has been proven in postoperative pain reduction for patients diagnosed with varicose veins of the lower extremities. The investigators intend to evaluate the feasibility of the preoperative MFF administration for the postoperative pain reduction and the decrease of the postoperative complications in patients with hemorrhoidal disease.

Group Intervention Description Experimental group micronized flavonoid fraction Patients of the experimental group received Detralex® 1000 mg QD for 15 days before the operation, 3000 mg starting from day 1 after the surgery for 4 days, then 2000 mg for the next 3 days and 1000 mg till day 30 after surgery
- Primary Outcome Measures
Name Time Method rate of prescribing opioid analgesics 7 days after surgery the rate of prescribing opioid analgesics to prevent the pain from rising above VAS 5 after surgery
- Secondary Outcome Measures
Name Time Method other medications use 7 days after surgery the need for other medications after surgery
complication rates within 30 days after the procedure bleeding, urinary retention, infectious complications
pain at rest and during defecation 15 days after surgery The pain was assessed using a visual analogue scale (VAS, 0 to 10 points, where 10 is the maximum score).
readmission rate 30 days after surgery The life quality rate 7 and 30 days The overall quality of life was assessed using the EQ-5D patient questionnaire.
time from surgery to return to work during 30 days after surgery
