[Prognosis of early outcomes of severe craniocerebral injuries depending on duration of neurological syndromes and complications].

A mathematical model is presented of prognosis of early (within the periods of stationary treatment) outcomes of a severe cranio-cerebral injury according to the main indicator--"favorable outcome--discharged from the hospital", "unfavorable outcome--died" depending on 10 indicators characterizing the patient's age, injury, duration of neurological syndromes and intraoperative, intracranial postoperative and somatic complications. The model was developed with the help of Excel and the application software Statistica and SPSS for Windows. For the development of the model of the correlative and discriminant analyses were used. The calculation of the prognosis can be made with the help of a computer or a microcalculator.

[The surgical procedure in ulcerous duodenal hemorrhages].

Available are the results of treatment of 493 patients with duodenal ulcer complicated by bleeding in the center of gastro-intestinal bleedings at N. I. Pirogov City Hospital No. 1 in 1995-1996 years. 74 patients were operated. Overall lethality made up 1.8%, postoperative lethality rate--8.1%. In ulcer of posterior wall of the duodenum, 10 mm and more in diameter with blood loss of medium and high degree, the number of relapses made up 57.1%. In cases of urgent operations (n = 30); carried out on the first day of admittance to the hospital, 1 patient died. Expectant policy in treatment of patients with ulcer of posterior wall of the duodenum results in poor effect of the treatment and complications (4.1%). The advantages of active individual approach in treatment of patients with acute duodenal bleeding are outlined.

[The invasion of a tumor into the bronchial wall in central cancer of the lung].

The paper analyzes histological findings of a number of bronchial sections made proximal the visible margins of a tumor in 54 patients operated on for central cancer of the lung. In coincidence of micro- and macroscopic limits of the extension of tumor cells was revealed in 29 (53.7%) patients. Statistical analysis revealed that the extension of tumor invasion obeys the exponential law of distribution. Probability of detecting tumor cells at various distances from the visible margin of the tumor was found. The findings suggest that one may predict that tumor cells can remain in the bronchial stump depending on the level of its elimination.

[Surgical prevention and treatment of gastroesophageal hemorrhage in portal hypertension].

The article discusses the techniques of a two-stage combined separating intervention and instrumental division of the esophagus for the prevention and treatment of gastroesophageal hemorrhage in portal hypertension. The sequence of the stages of the operation is determined according to the emergency situation, the condition of hepatic function, and the presence of signs of hypersplenism. Separating interventions were carried out in 12 patients, one patient died in the immediate postoperative period. Complications were encountered in 4 patients. The patients who survived were examined in follow-up periods of 3 to 14 months, neither recurrent hemorrhages nor hepatic encephalopathy occurred. Varicosity of the esophageal and gastric veins disappeared and reduced in 10 patients.

[Therapy and prophylaxis of eventration].

The author observed 86 patients with eventration which was caused by progressive peritonitis in 49 and by suppuration of the laparotomy wound in 27. Only in 10 patients the eventration was not a consequence of a pyoinflammatory process. The surgeon's is suggested according to the type of the eventration.
