Visualization of the relief of the human body using stereo photography and quantification of its parameters.

An improved method for digital stereo photography for a living object allowed us to register the relief of human back as the indicator of dysplastic process or effectiveness of its treatment. We proposed a set of relief parameters to evaluate quantitatively the shape of the back in the dynamics. Three methods of assessment of varying difficulty are discussed. The safety and accessibility of the method of stereo photography allows us to study the development of dysplastic processes at the early stage, first of all in children.

[Early postoperative hyperlactatemia in patients after surgery under extracorporeal circulation].

Metabolic disturbances, such as changes in blood acid-base balance and electrolytic composition; hyperglycemia and hyperlactatemia, are frequent factors that complicate the early postoperative period in patients after cardiac surgery under extracorporeal circulation. The purpose of the study was to estimate the incidence of hyperlactatemia in the early postoperative period and to reveal the predictors of its occurrence. This prospective study was conducted in our center from November 14, 2006, to September 1, 2007. The study covered 270 patients above 15 years of age, who had been operated on for coronary heart disease, acquired heart diseases, and combined lesions of valves and coronary arteries. Hyperlactatemia was observed in a substantial proportion of patients who had been operated on under extracorporeal circulation. Correlation analysis indicated a significant association between the duration of extracorporeal circulation and the magnitude of hyperlactatemia developing in the early postoperative period. Hyperglycemia with a glucose level of > 9 mmol/l is a predictor of the development of hyperglycemia.

[The diagnosis and treatment of wounds to the lumbar area].

An analysis of results of treatment of 228 patients with wounds of the lumbar region has shown that in 66.2% of cases they were not penetrating, in 33.8% they were penetrating. In 42 patients there were injuries of internal organs and of the vessels of the abdominal cavity and retroperitoneal space. The casualties must be examined under conditions of the emergency operating room and which in addition to thorough revision of the wound must include subsidiary methods of examination: USI, survey radiography of the thoracic and abdominal cavities and diagnostic survey laparoscopy, if necessary.

[Injuries of the duodenum].

Based on an experience with treatment of 68 patients with injuries of the duodenum the authors have developed a diagnostic algorithm always permitting the diagnosis of injuries of the retroperitoneal part of the duodenum. A classification of severity of the duodenal injury was proposed determining the volume and type of surgery. Using the proposed therapeutic-diagnostic program decreased postoperative lethality from 52.4% to 11.8% in patients with wounds and from 60% to 13.4% in patients with closed injury of the duodenum.

[Acute gastrointestinal bleedings of tumorous etiology].

A retrospective analysis of treatment of 436 patients with acute bleedings from tumors of the gastrointestinal tract was made. Elderly and senile patients made up 72% of the hospitalized patients. The emergency complex diagnostics in 75% of the patients under conditions of a multi-profile hospital allowed the source of bleeding to be detected during the first day, the strategy of treatment being also determined. Radical operations could be fulfilled both in emergency and planned order on most patients. Lethality of patients with tumors of the stomach and colon after radical operations was 10%, after palliative operations 29.5% and 27.9% respectively. Acute bleedings from tumors of the gastrointestinal tract is not the absolute sign of the patient being inoperable.

[Method of cover of "difficult" duodenal stump in resection of the stomach].

The experience with 233 stomach resections in "difficult" ulcers is analyzed. The main cause of complications and lethality after these surgeries is duodenal stump sutures insufficiency seen in 17 (7.3%) patients, and in 10 (4.3%) patients it was the cause of death. Original duodenal stump cover was performed in 86 patients. There were no cases of suture insufficiency, two patients died of pneumonia and hepatic failure.

[Specific topographic-anatomical and technical features of resection of the stomach by the Roux method].

The topographic-anatomical investigations of the extraorganic part of the arterial and nervous systems of the duodenum and the initial part of the jejunum in combination with the results of the clinical use of gastric resection by the Roux method allowed to draw a conclusion that the development of Roux syndrome can be prevented by a transection of the jejunum with the saved arcades between the first jejunal artery, the duodenal branch and the second jejunal arteries. The rules of gastric resection by the Roux method and indications to this procedures in patients with ulcer disease of the stomach and duodenum are described. Good and excellent long-term results were obtained in 75.8% of the patients operated upon.

[Hemodynamic features during coronary bypass surgery on the working heart].

Changes in hemodynamics and blood oxygen transport function were studied during coronary bypass surgery (CBS) on the working heart under anesthesia with propofol and fentanyl. In patients operated on the working heart, the course of the basic stage of an operation was characterized by a moderate reduction in cardiac index and stroke volume due to the cardiac changes and immobilization, which resulted in cardiac compression and venous return deterioration. These impairments did not lead to worse oxygen-transportfunction and they were completely eliminated in the rehabilitative period. Analyzing the results of studies of troponin-T and creatinine kinase-MB showed that the procedure of coronary bypass surgery without using EKK had a less damaging effect on the myocardium. Analyzing the course of an early postoperative period indicated that the use of perfusionless technology substantially reduced needs for inotropic support, the time of artificial ventilation, and the length of stay at an intensive care unit.

[Diagnosis and treatment of wounds of the gluteal area].

The authors present results of surgical treatment of 98 patients with gluteal wounds. In 93.9% of cases the wounds were not penetrating and in 6.1% there were penetrating wounds. All the patients admitted to hospitals in state of shock as well as suspected to the penetrating character of the wound underwent general laparoscopy. In 2 patients with penetrating wounds of the abdominal cavity and in 7 patients with non-penetrating wounds ligation of the internal iliac artery was necessary because of huge bleeding. Two patients (2%) with penetrating wounds of the abdominal cavity died.

[Specific features of surgical strategy in gastroduodenal ulcer bleedings in elderly and senile patients].

An analysis of results of surgical treatment of 107 elderly and senile patients with gastroduodenal ulcer bleedings was made. Emergency operations were fulfilled on 47 patients, urgent operations on 56 patients and planned operations--on 4 patients. Ulcers of large size prevailed. Most of the patients had complications of ulcer disease. Palliative interventions were performed on 27 patients: suturing the vessel--in 20, ablation of the ulcer--in 7. Lethality was 33.3%. Radical operations were performed on 80 patients: resection of the stomach--in 75, vagotomy--in 5. Lethality was 16.3%.

[Surgical strategy for wounds of the cervical part of the esophagus]. / Khirurgicheskaia taktika pri raneniiakh sheinogo otdela pishchevoda.

An analysis of results of treatment of 425 patients aged from 15 to 85 years with penetrating wounds of the neck was made. In 40 (8.1%) patients there were wounds of the cervical part of the esophagus, 29 of them had associated injuries. The proposed active surgical strategy consisted in a necessary thorough revision of the penetrating wounds of the neck using general anesthesia and then directly in the operation room using subsidiary methods of examination such as urgent x-ray analysis with a water-soluble contrast, esophagoscopy, larengotracheoscopy. This approach allowed detection of injuries of the cervical part of the esophagus, even in cases of the absence of clinical symptoms of esophagus injuries. In all the patients the wounds of the esophagus were sutured and followed by active aspiration drainage and antibacterial treatment with modern antimicrobial medicines.

[The diagnosis and treatment of injuries of the upper respiratory tract in wounds and traumas of the neck]. / Diagnostika i lechenie povrezhdenii verkhnikh dykhatel'nykh putei pri raneniiakh i travmakh shei.

The authors made an analysis of results of treatment of 339 patients with wounds and closed injuries of the neck. Laryngotracheal injuries were found in 27 (7.9%) patients, in 15 patients the injuries being of combined character. Active surgical strategy including the necessary thorough revision of the penetrating wounds of the neck during operation under general narcosis anesthesia, by instrumental methods of examination. Such strategy allowed timely detection and adequate elimination of injuries of the organs and vessels of the neck and improvement of the results of treatment of such patients.

[Acute tumorous obstruction of the colon in elderly and senile patients]. / Ostraia opukholevaia neprokhodimost' obodochnoi kishki u bol'nykh pozhilogo i starcheskogo vozrasta.

The authors present the results of surgical treatment of 106 elderly and senile patients. In 30 patients admitted in a extremely severe condition the acute intestinal obstruction was combined with peritonitis. Postoperative mortality in this group of patients was 86.7% in spite of intensive treatment. In 28 patients generalization of the process was detected and they were given palliative interventions for liquidation of acute intestinal obstruction. Postoperative mortality in this group was 39.2%. Conventional radical operations were fulfilled on 48 patients. Postoperative mortality in this group was 20.8%. Later on the intestinal patency was reestablished in 15 patients. The data obtained show the possibility to widen the indications to radical operative interventions and to improve results of treatment of such patients.
