SUBSTANCE: method involves removing an epithelial layer, exposing a cornea by saturating it through multiple instillations of 0.1% riboflavin followed by the ultraviolet exposure. After the epithelial layer has been removed, a ring made of an ultraviolet-protected contact lens is applied on a surface of the eyeball perilimbally. An outer diameter of the ring covers the limb by no more than 2 mm, whereas an inner diameter of the ring is equal to a basic diameter of the keratoconus. The whole duration of the ultraviolet exposure involves additional instillations of riboflavin on the cornea every 3-4 minutes. The exposure is characterised by wavelength 365 nm, power 3.0 mWt/cm2 at 50 mm for 30 minutes with the ring to be removed after the exposure is completed.

EFFECT: method is easy to implement, involves no difficulties for specialists, providing higher clinical effectiveness by limiting the ultraviolet exposure area, preventing the ultraviolet involvement of the limb and reducing a risk of postoperative complications.

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.

SUBSTANCE: duodenoscopy is performed with the use of an endoscope with its inspection window on the side. The greater duodenal papilla is visualised. It is cannulated with a Teflon catheter with a working end having an aperture in the middle. An end face of the working end of the catheter is inclined at an angle of 45°. Two apertures of 0.2 cm in diameter are arranged oppositely diametrically on its sides. The first aperture is arranged at 0.4 cm from the end face. The second is found at 0.8 cm. A metal lift is actuated to advance the catheter into a lumen of the common bile duct. A sterile syringe is attached to a connector of the catheter; the syringe is pulled out to draw the bile into the catheter. The syringe piston is pulled out to a 8 ml mark and then released. The manipulation is repeated until the bile penetrates into the syringe. After the bile ingress into the syringe is visualised, the piston is pulled out to a 5 ml mark. A 2-second pause is made. The piston is released. In the course of bile aspiration, the catheter is advanced along the common bile duct 1-2 cm above.

EFFECT: method enables fast and effective bile aspiration from the lumen of the common bile duct, preparation of the material free from the intestinal discharge and pancreatic fluid, as well as reduces a risk of the catheter suction to a wall of the common bile duct ensured by the catheter structure and a certain sequence of the syringe piston motions.
