[Selection of the surgical approach to the adrenal glands and means of reducing suppurative complications in Cushing syndrome].

Based on their experience with 230 operations on patients with the Icenko--Cushing syndrome the authors made a conclusion that the oblique-transverse lumbar access through the XIth intercostal space was preferable in patients with newformations of the adrenals with the diameter not less than 4 cm. The exclusion was a great tumor on the right adrenal. In these cases a good access to the adrenal was provided by lateral thoracophrenotomy through the Xth intercostal space. The lumbar access in question followed by the active drainage through a special wound is thought to be preferable.

[Complaints concerning the digestive organs in virtually healthy persons].

The specially developed questionnaires were completed by interrogating 126 practically healthy people. It was established that when studying the long-term results of operations on the stomach one should not restrict himself by general questions about the patient's health but it is necessary to use a special questionnaire. After vagotomy about 3-6% of such patients have pronounced disorders of digestive organs which could hardly be associated with the operation itself.

[Malignant stomach ulcer].

The authors present data of the clinical X-ray and morphological diagnostics of malignant gastric ulcers revealed in 96 patients. The total number of patients with gastric ulcer operated upon was 642. The morphological findings may serve the only reliable criterium of malignancy. Results of the operative treatment of such a malignant ulcer of the stomach are dependent on the spread of malignant invasion in the gastric wall. Treatment of patients with the involved mucosa only gave 5-year survival in 89.5%. Spread of the malignant invasion throughout the whole thickness of the gastric wall--50.0%. In patients with metastases into lymph nodes (independent of the invasion into the gastric wall) 5-year survival made up 29.4%.

[Comparative data on the healing of surgical wounds of the stomach made by ordinary, laser and ultrasonic scalpels].

The article presents comparative morphological data on the healing of operative wounds on the stomach of rabbits made by an ordinary, laser and ultrasound scalpels. In all the cases the wound was sutured by a one-row interrupted sero-muscular stitches. Clear distinctions in the healing of postoperative gastric wounds made by different scalpels were established. The formation of a zone of coagulative necrosis, followed by rejection of necrotic masses was invariably noted after the laser and ultrasound scalpels. These zones were not so considerable after dissecting the stomach with an ordinary scalpel. No incompetent sutures, failure of their hermetic quality or any other complications in the process of scar formation were detected in all the series.

[Various features of anesthesiologic provisions for surgery of pheochromocytoma].

The examination of 46 patients with pheochromocytoma has shown all the patients to have cardiac insufficiency before operation. This finding shows the necessity of preoperative preparation of the myocardium. The standard administration of beta-adrenoblocking agents without controlling the parameters of central hemodynamics can cause insufficiency of the minute volume of blood circulation. The authors failed to reveal advantages of any kind of general anesthesia. They consider that all the efforts in the course of anesthesiologic measures should be directed to the correction of hemodynamics.

[Cholecystolithiasis after vagotomy].

On the basis of experiments in animals (examination of bile after vagotomy), results of clinical observations of 450 patients after vagotomy and the state of motor and evacuatory functions of the gallbladder the authors make a conclusion that vagotomy in itself does not cause cholecystolithiasis.

[Various problems in the pathogenesis and surgical treatment of patients with hypercortisolism].

Based on an analysis of clinical and laboratory data, results of histological examination of removed adrenals and tumors of the cortical layer as well as an assessment of the functional state of the hypothalamo-hypophyseal-adrenal system in 132 patients the authors discuss some debatable questions of pathogenesis and selection of methods of treatment of the disease known as the Icenko--Cushing disease and syndrome.
