Outcome Measures

Primary Outcomes (1)

  • The pain syndrome severity score (spontaneous pain) of the visual analog scale (VAS)

    The change in the pain syndrome severity score (spontaneous pain) of the visual analog scale (VAS) on day 7 after the intervention as compared with the baseline value at the V0 visit.

    7 days

Secondary Outcomes (14)

    14 days

  • Pain syndrome - Spontaneous pain (2)

    25 days

  • Use of analgesics

Study Arms (2)

Group N 1

This study is non-interventional and has an observational nature, so randomization is not provided for it. This protocol will use the approach with random allocation of sites into clusters depending on the postoperative treatment strategy, acceptable for an observational study. In order to maintain a balance between the number of patients receiving MPFF and those not receiving any systemic venoactive drug, a random distribution of research sites into two clusters will be performed by compiling a table identical to the randomization tables for clinical trials. The study sites allocated to the first cluster will recruit patients who meet the criteria for the group N 1 - those with planned prescription and use of MPFF after the minimally invasive surgical intervention

Group N 2

The study sites allocated to the second cluster will recruit patients who meet the criteria for the group 2 - those without the planned prescription of any systemic venoactive drugs after the minimally invasive surgical intervention

patients with haemorrhoids undergoing minimally invasive surgical interventions

You may qualify if:

  • Males and females aged over 18 years.
  • Absence of conditions requiring urgent medical care.
  • The patient was diagnosed with chronic hemorrhoids of grade 2 or 3 according to Goligher classification.
  • laser vaporization (laser submucosal destruction or ablation);

  • transanal dearterialization + laser vaporization (laser submucosal destruction or ablation);
  • transanal dearterialization + sclerotherapy.

You may not qualify if:

  • Pregnancy or breast-feeding, or planning for pregnancy during the study or at least in two months after its completion.
  • Confirmed or suspected malignancy.
  • Severe somatic disorder (of heart or blood vessels, lungs, kidneys, pancreas, or liver), accompanied by the organ function decompensation.
  • Mental disorder.
  • Contraindications for examination.
  • Predicted unwillingness of the patient to follow the protocol of treatment and supervision, poor adherence to treatment.
  • Patient's participation in any interventional/observational study at the present time.
