Method for predicting potential efficacy of endoscopic treatment of vesicoureteral reflux

FIELD: medicine.

SUBSTANCE: invention relates to medicine, surgery. Predict the effectiveness of endoscopic treatment of vesicoureteral reflux in children. At the mouth of the ureter, a ureteral catheter with a measuring scale is inserted through the working channel of the cystoscope. Cystoscope is deflected axially upwards relative to plane of operating table by no more than 20°. Model the endoscopic correction of the shortening of the submucosal ureter. Deformation of ureteral anterior wall is visually determined when end of catheter is moved from intramural to submucosa. Determine the length of the submucosa of the ureter. Length of no more than 2 mm is regarded as adverse predictor of the effectiveness of endoscopic treatment.

EFFECT: method for predicting the potential efficacy of endoscopic treatment of vesicoureteral reflux is proposed.

SUBSTANCE: pre-operative fasting venous blood 1 ml is sampled at room temperature 20-24°C into an anticoagulant-free vacuum system (test tube). The test tubes are delivered in a sealed container at temperature 2-8°C for 2 hours to a laboratory for immunoenzyme assay and analysed to determine anti-thyroid stimulating hormone receptor antibodies. If the antibody level is 1.5 units/l or more, a thyroidectomy is performed, whereas the antibody level of less than 1.5 units/l requires performing a subtotal thyroid resection according to standard techniques.

EFFECT: invention enables reducing a probability of recurrent thyrotoxicosis in the patients after subtotal thyroid resection.

SUBSTANCE: planned skin incision is first configured on an anteriolateral neck surface by projection zoning of a clavisternomastoid and a neck median line to be marked with colour graphic lines. A first line extends along a medial border of the clavisternomastoid. A second line extends from a suprasternal notch to the middle of a hyoid shaft. Both of the lines are then combined by drawing a perpendicular third line from a lower border of the middle of a hyoid shaft to the medial border of the clavisternomastoid, thereby forming a projection triangle. Cutaneofascial layers, platysma and subcutaneous fat are incised along the first and third lines to cut out a musculocutaneous flap, which is brought outwards. Underlying soft tissues are dissected to an anterior surface of cervical spinal bodies by splitting subcutaneous fat between a neurovascular bundle and a pharynx, detaching an intracervical fascia, splitting perioesophageal subcutaneous fat and displacing midline organs of the neck in the medial direction, and the neurovascular bundle - in the lateral direction.

EFFECT: method enables reducing a risk of treatment-induced traumatic injuries of the midline organs of the neck, an upper laryngeal nerve, upper and lower thyroid arteries, as well as a parenchyma and an excretory duct of a submandibular salivary gland with optimising topographo-anatomical relations of the incision wound structures, thus providing a surgical angle approaching 90 degrees.

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.
