RESUMO
Perivascular epithelioid cell tumors is a group of rare tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. There are no specific imaging sighs. In most cases, the final diagnosis is possible only after the immunihistochemical study. These tumors are extremely rare. We present imaging findings of two cases of perivascular epithelioid cell tumors of the liver.

Nine patients were operated on with the use of robotic complex. In 3 cases the nonorganic retroperitoneal pelvic tumor was removed, the 4 full-layer urinary bladder and ureteral orifice resections and simultaneous ureteral plasty together with ileal-obturatory lymphadenectomy (2 - cancer of the urinary bladder cervix, 1 - pheochromocytoma of the urinary bladder) and 2 ureterocele with complete ureter duplication and megaureter were performed. Technical aspects of the robotic layerwise resection of the neck of the urinary bladder were worked out. The operation time varied from 1 hour 45 minutes to 4 hours 45 minutes. The maximal blood loss was 100 ml. One patient developed the acute respiratory failure. The were no other postoperative complications. The postoperative hospital stay was 7-12 days.

The experience of single institution of 43 robotic-assisted operations in the abdomen and retroperitoneal space has been analyzed. The problem of port placement conditioned the preoperative computed 3D-modelling of the operative course. The procedure allowed to optimize the movements of the robotic manipulators, decrease the risk of organ injury and overall incidence of intra- an postoperative complications.

Some ways to improve informative capacity of ultrasonic diagnostic examinations are discussed, and their application in an extended network of outpatient clinics by using the state-of-the-art automated devices, microcomputers and microprocessors in particular, are considered. Possible approaches to automating ultrasonic diagnostic examinations are analysed, and requirements for hardware and software of ultrasonic complexes are specified. A configuration structure of complexes for processing monodimensional and bidimensional echo signals is presented.

An optimal modification of the patients flow arrangement is offered for more convenient form and methods of the population screening for malignant tumours and precancerous diseases, aided by medical and computer techniques. A scheme of the mass-screening system and principal aspects of technical provision particularly for oncological screening are presented.

A device for collecting medical history data, using the microprocessor K580 and intended for work in the automated system for mass prophylactic surveys, is discussed. The device is realized in 2 variants: working autonomously or in combination with computers of a higher level. The structural diagrams of both variants and the software for the autonomous variant are described.
