SUBSTANCE: ventral release from a toracotomy approach at an apex is accompanied by excising the seventh, or eighth, or ninth rib to gain an access in the form of an autograft 15-20 cm long. An excised rib autograft is placed into a pocket bed pre-formed from the toracotomy incision in subcutaneous fat and fixed to the subiculum to be used as the autograft; the excised rib autograft is underrun for a period from the moment of the final stage of dorsal correction. The second stage of the surgical treatment is preceded by vertical dry halotraction under the patient's body standing in the space of a therapeutic four-wheel frame equipped with a telescopic arm for the patient's head suspension. At the stage of the dorsal correction, the excised rib autograft is removed through a 2-3-cm incision along the postoperative toracotomy scar from the pocket bed in the subcutaneous fat, cleaned from soft tissues, treated in the antiseptic solution, and placed onto the decorticated posterior elements of the operated spine.

SUBSTANCE: invention relates to medicine, namely to neurosurgery, neurooncology, and can be used for the treatment of glial brain tumours of a supratentorial localisation. For this purpose photodithazine in a dose of 1 mg/kg of body weight is introduced to a patient 2 hours before the tumour ablation. After that, surgical access to the tumour is performed. The operation wound is illuminated by blue colour with a wavelength of 400 nm, and the tumour boundaries are determined by means of fluorescence of photodithazine, selectively accumulated in the tumour tissue. The tumour is ablated under control of the tumour luminescence in blue colour with the application of an operation microscope. After that, a flexible light guide from a radiation source with a wavelength of 662 nm and power of 2.0 W with a light dispersing nozzle is placed into the tumour bed and the perifocal zone of the tumour is irradiated. The dose of irradiation is determined by the disappearance of fluorescence.

EFFECT: method provides an increase of the treatment efficiency due to the reliable clear determination of the tumour tissue boundaries with the normal brain substance independent on the malignancy degree and character of the tumour growth, with an increase of its ablation radicality, as well as due to the destruction of cells, located in the perifocal zone.

That is followed by performing the stage f) that involves removing the tip from the hollow organ lumen. That is followed by performing the stages a, b, c, d and f again in the same sequence from the other side of the second connected structure. After both connected organs are sutured together, the spring-assisted plates are removed from the outer surface; both ends of the same needle sutures brought through the wall of the connected organs are found in each spring sector. The plates with sutures are diverged, and both halves of the surface and the tipped rod are sequentially removed from a surgical site.

An opening 1.5 cm long is formed from an opposite end of a gastric stump. The Roux isolated enteric loop is formed. An enterotomic opening is formed at 5 cm from the stump of the Roux isolated enteric portion. One branch of the linear stapling apparatus is inserted into the gastric lumen through the provided gastrotomic opening of the stump towards a greater curvature. The second branch is inserted through the enterotomic opening towards the enteric stump. The gastroenteroanastomosis is partially formed. The rest portion of the gastroenteroanastomosis is formed between the gastric stump and the enteric enterotomic opening by an uninterrupted manual suture.

SUBSTANCE: invention refers to medicine, namely to surgery, and can be used in a laparoscopic hepaticojejunostomy accompanying pancreatoduodenal resection. A pancreatectomy is performed. A side-to-end pancreaticojejunoanastomosis is created on the Roux isolated jejunal loop. The hepaticojejunostomy follows. An intestinal lumen is exposed at 10-15 cm from the created pancreaticojejunoanastomosis; the opening diameter is equal to that of a common hepatic duct. The needle is first pricked in a point of 9 o'clock. After knotting, traction of a free end of the needle is generated to extend a posterior wall of the common hepatic duct. A posterior lip of the anastomosis is created by locking continuous stitching at 0.1-0.3 cm to the level of 3 o'clock. The second knot is formed. An anterior lip of the anastomosis is created by locking continuous stitching at 0.1-0.3 cm. Once reaching the position of 9 o'clock, the free ends of the suture are tied together.

EFFECT: method provides reducing the intraoperative injuries, the length of treatment, and the risk of postoperative ventral hernias by applying the laparoscopic approach involving no injuries of the muscles of the anterior abdominal wall and providing the reliable anastomosis to be created.

SUBSTANCE: invention refers to experimental medicine and immunology, and can be used for the assessment of the millimetre-range electromagnetic wave (EHF) effect within a three-component model of cytostatic exposure. That is ensured by a thymus exposure in the group of animals to the millimetre-range electromagnetic wave (EHF) effect at wavelength 5.6 mm for 2 weeks every 1-2 days. A single exposure of the physical factor makes 1-2 minutes for 2 weeks every 1-2 days. That is followed by simulating a surgical intervention by opening and closing a peritoneum. On the seventh postoperative day, the animals are exposed to three-fold fractionated external gamma exposure in a single dose of 2.5 Sv every single day. Thereafter, cyclophosphan is administered intraperitoneally in a dose of 4 mg/100 g of animal's body weight. On the 14th day after the cytostatic is administered, the animals are killed to examine their blood and immune competent organs. That is combined with determining a thymus cellularity (TC) in 106cell./100 mg of its weight, a functional lymphocyte activity in a nitroblue tetrazolium test (NTT) in units, a spleen antibody-forming cell (AFC) count according to N.K.Erne in cells/"чП", apoptosis in an annexin test (AT), %, blood serum circulating immune complex (CIC) in units. That is followed by calculating a physical factor effect index (FI) by formula: FI=AT×NTT×TC×100CIC×AFC. If the FI is less than 48, the presence of the immunomodulatory effect of the EHF-exposure is stated.

EFFECT: method provides the objective assessment of the millimetre-range electromagnetic wave (EHF) effect within the three-component model of the cytostatic exposure.
