FIELD: medicine.;SUBSTANCE: method of laparoscopic spleen resection refers to medicine, namely to abdominal surgery. Patient is placed on the operating table on his/her back in the Fowler position. Under aseptic conditions under combined intubation anaesthesia in a supraumbilical region, a skin incision of 1 cm is performed, laparolifting is performed by means of clamps, and laparocentesis is performed with a Veress needle. 10 mm camera trocar is introduced with a viewing angle of 30 degrees; the instrument trocars are introduced under the control of an optics in the proposed topographic-anatomical area of the operation. Thunderbeat apparatus is used to open an omental bursa, and a gastro-splenic or colonic-splenic ligament is transected depending on the localization of the pathological focus and the required resection border. Spleen is mobilized; a splenic artery is separated at distance of 4 cm in the proximal direction from the splenic hilum to the point of branching into segmental arteries from the surrounding tissues; a soft vascular DeBakey clamp is applied on the artery with a laparoscopic clamp. Using the Thunderbeat apparatus, a pathological neoplasm is resected along the border of a healthy tissue, haemostasis of the resection line is performed by bipolar coagulation, haemostatic plates Tachocomb and haemostatic system PerClot are applied to the resection site, resected area is placed in a plastic container, removed from the abdominal cavity through a minilaparotomic incision in the left iliac region.;EFFECT: method enables performing a surgical intervention on a "dry" surgical site, which provides adequate haemostasis and visibility of clear boundaries of the resection of the organ; perform an economical resection of the organ, thereby maximally preserving the immunological and hematopoietic functions of the spleen; allows performing surgical intervention on various topographic and anatomical areas of spleen due to convenient viewing angle; also minimally invasive approach allows reducing pain syndrome and accelerating postoperative rehabilitation, which reduces time of patient’s stay in hospital.;1 cl, 1 ex
