[Development of navigation technologies for ambulatory surgery].

The article considers the main directions in the development of navigation surgical technologies allowing to decrease traumatic effects of certain operative interventions and to fulfill them in "one day" hospitals. The historical aspects of navigation surgery are given as well as a classification of the navigation interventions and examples of the newest of them used at the present time in the Medical Center of Bank of Russia.

[Technologies of ambulatory surgery].

The development of the outpatient surgery in Russia is thought by the authors to be very urgent if compared with the experiences of foreign clinics. In 1998 a Center of the outpatient surgery was set up in the Medical center of the Bank of Russia where the planned surgery treatment was performed in the regimen of the one-day hospitalization. The ultrastructure of the unit and problems of the outpatient surgery technologies are discussed. The first experiences with performing 313 ambulatory interventions concerned with surgery, traumatology and cosmetology are analyzed.

[Therapeutic interventions under ultrasonic control in diseases of the abdominal cavity organs].

The results of 212 transcutaneous therapeutical abdominal interventions, performed under the ultrasound control, have been analysed. 190 patients have been treated. The sectorial ultrasound probe was acting at the frequency of 3 MHz. The electronic matrix guided the needle. One-stage percutaneous drainage with an "umbrella" stylet catheter was used in all cases. Percutaneous drainage of the gallbladder was performed in 140 patients; 111 of them had acute cholecystitis with a high surgical risk. The operation of cholecystectomy has been performed in 32 patients after control of the acute stage of the disease. In 47 patients percutaneous drainage was indicated in case of liver cysts and abscesses, intraliver hematomas, liver pseudocysts, liver pseudoabscesses, abdominal abscesses. These types of curative procedures have limited contraindications, can be performed irrespective of the patient's condition, and in certain cases may be an alternative to major surgical interventions.

[Polymer materials in laparostomy of peritonitis].

Cleansing of the abdominal cavity by the open method-laparostomy and the use of polymer materials-was conducted in 85 patients with generalized peritonitis (mainly due to perforation of a malignant tumor of the colon). With the use of this method the incidence of purulent complications reduced from 50% to 35.2% and mortality from 42% to 25.8%.

[The surgical treatment of patients with colonic cancer complicated by perifocal inflammation of the tissues].

In the clinic, at preoperative preparation of the patients with cancer of the colon complicated by perifocal inflammation, the irrigation of a tumour area, using antibacterial preparations, is employed. After laparoscopy, a drainage tube with microirrigator for perfusion of the antibacterial solution is introduced to the region of tumour location. Using the method described, 25 patients were prepared for the operation. Their state improved after 7-8 days. One-stage radical operation was performed in 20 patients. Of them in 17, primary intestinal anastomosis was created.

[Loop colostomy in patients with cancer of the colon and rectum].

At the clinic of Scientific Research Institute of Proctology, Ministry of Public Health of Armenia, in 97 patients with complicated cancer of the colon and rectum, a two-barrel loop colostomy was created for the recent 10 years. Use of intraperitoneal method contributed to 3-fold decrease in incidence of postoperative purulent complications. Irrigation of a tumour site with antibacterial preparations in perifocal inflammation of colonic cancer together with carrying out the complex antibacterial therapy permits to perform the radical operations.

[Microcholecystostomy].

Treatment efficacy was compared for transcutaneous transhepatic microcholecystostomy controlled by laparoscopy (75 patients) against that controlled by ultrasound scanning (67 patients) principally in acute cholecystitis. Basic indications for microcholecystostomy are a high operative risk in elderly patients and decompression of the bile ducts for obstructive jaundice. Four patients (2.8%) developed postmicrocholecystostomy complications treated by urgent surgery. The manipulation is short-term, simple and is well tolerated even in grave condition. This makes microcholecystostomy an alternative to cholecystostomy.

[Mechanical jaundice in cholangitis].

The peripheral lymph of the leg and venous blood from donor volunteers were compared. The lymph was found to issue at a higher rate in the active period of the day (from 9 a. m. to 9 p. m.) than at night (from 9 p. m. to 9 a. m.) and is equal to 0.45 and 0.22 X 10(-3) litre/hour, respectively. Its cell composition was lower than that of the peripheral blood (lymph, 2.04 X 10(7) cell/litre; blood, 509 X 10(7) cell/litre) with erythrocytes and platelets not taken into account. Lymphocytes (over 90 per cent) and monocytes (9 per cent) prevailed; the cell number varied with the time of the day; at daytime it was 5-6 times greater than at night. The immunological parameters of the lymph were characterized by a lower content of B cells, greater proportion of 0 cells, and a close T-cell proportion, the active lymphocytes being prevalent. This T-cell proportion correlated with higher spontaneous and lower PHA-induced proliferative activities. The lymph immunoglobulin level was 10-27 per cent of the serum immunoglobulin level; a relationship was observed between the plasma and lymph levels in different age groups.
