METHOD FOR LASER TREATMENT OF ACUTE THROMBOSIS OF EXTERNAL HAEMORRHOID Russian patent published in 2025 - IPC A61B18/20 A61B17/3211 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to surgery and coloproctology. External haemorrhoid is separated under infiltration anaesthesia. Longitudinal incision up to 1 cm is made with a pointed scalpel above an external haemorrhoid. Thrombic excision is performed with the use of a Volkmann spoon by pressing a haemorrhoid base and advancing towards the incision. Haemorrhoid cavity is washed with hydrogen peroxide H₂O₂ – 3% and dried. Metal conductor with a conical light guide of BIOLITEC AG laser is inserted through the formed wound defect: Ceralas, in the form of a pike, which is brought through tissues to a haemorrhoid base. Continuous laser coagulation of an external haemorrhoid is performed at wave length 1470 nm, power 8 W with traction of a laser light guide from a haemorrhoid base to a wound edge, and the laser light guide is removed.

EFFECT: method allows to eliminate the risk of bleeding and recurrent thrombosis in the external haemorrhoid; eliminate risk of recurrence; shortening the patient's rehabilitation time; excluding inflammatory and purulent-septic complications of the anorectal zone.
