[Perioperative augmented reality technology in surgical treatment of locally advanced recurrent rectal cancer]. / Perioperatsionnoe primenenie tekhnologii dopolnennoi real'nosti v khirurgicheskom lechenii bol'nogo mestnorasprostranennym lokoregionarnym retsidivom raka pryamoi kishki.

Rectal cancer occupies the leading position among cancers, and incidence of locally advanced recurrences is still high despite comprehensive treatment. Combined resections are usually associated with high perioperative risks. These procedures are technically complex interventions requiring further improvement. Virtual reality technology in surgical treatment of locally advanced rectal cancer recurrence has not been widely discussed. The authors present multidisciplinary construction of the matched topographic-anatomical virtual model and virtual planning of the combined surgical intervention. Intraoperative use of augmented reality allowed specifying topographic and anatomical features of surgical area, level of vascular ligation, localization of tumor fixation points and resection borders. These data ensured safety and quality of resection. Further research of augmented reality technology and improvement of its technical aspects will improve the results of surgical treatment of patients with locally advanced pelvic tumors and recurrences.

PREDICTORS OF FATAL OUTCOME IN PATIENTS WITH HEMORRHAGIC SHOCK IN GASTROINTESTINAL BLEEDING.

This work aimed to reveal the statistically reliable clinical and laboratory markers, which are associated with fatal outcomes in patients with hemorrhagic shock of the III degree on the stage of hospital treatment. It was stated that decrease of body temperature (till 35,9 °C), pH of venous blood (till 7,19) and content of ionized calcium (till 0,32 mmole/l) in venous blood and increase of lactate content (up to 4,1 mmole/l) in venous blood and rise of activated partial thromboplastin time (up to 59 sec) are connected with fatal outcomes.

[THE ADVANCED METHOD OF VESSEL SEPARATION AND HEMOSTASIS].

The authors suggested the advanced method of vessel separation and hemostasis, which was applied in 13 patients. This method was compared with the traditional method used for 8 patients. Proposed approach allowed separation of vascular fascicle twice faster than in usual way. There were noted a less decrease of hemoglobin level and shortening of hospital stay. The results of treatment were improved due to the application of the method of vessel mobilization and temporal hemostasis in surgery of stab-cut wound of the neck.

[Clinical assessment of various treatments for tracheal stenosis].

The paper deals with the management of cicatricial stenoses of the trachea, which is a topical problem of modern thoracic surgery. Surgical techniques and endoscopic operations aimed at expanding and maintaining the lumen of the airways have been employed. Original types of surgical operations and new endoscopic tools are proposed.

[The application of an impulse plasma jet for trauma of the liver]. / Primenenie impul'snoi plazmennoi strui pri travme pecheni.

The authors made an analysis of the application of a plasma jet with the help of an apparatus of original construction used for treatment of wounds of the liver in 36 patients. This apparatus has a number of advantages as compared with others. The plasma jet gives a reliable homostasis and minimum heat injuries to the liver tissues.
