[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.
