[Differentiated approach to the choice of the treatment method for pancreatic pseudocysts].

The results of treatment of 182 patients, suffering pancreatic pseudocysts, were analyzed. Total of 226 operative interventions were performed. Under ultrasonographic control 142 (78.02%) patients were operated, open surgical procedures were conducted in 68 (37.36%) patients. While doing selection of the operative intervention method it is mandatory to take into account not only the size and character of the cyst, but the pancreatic parenchyma and ductal system state, as well as the presence of complications. Application of a puncture-draining method in the pancreatic cysts treatment, which have originated after an acute pancreatitis, is effective in 71.08%, owes low of complications 2.41% and lethality 0.98%. While the pancreatic cysts treatment, which have developed as a consequence of chronic pancreatitis exacerbation, application of the cysts draining under ultrasonographic control is effective in 57.89% of the cases, and is performed in 15.80% as a first stage to stabilize the patient state and his preoperative preparation, correcting the signs of chronic pancreatitis and were conducted in our observations in 36.84% of patients. While the cysts are formatted on a chronic pancreatitis background practically all the gland becomes affected by chronic inflammatory process with degenerative-cystic transformation of pancreatic parenchyma, calculous changes and ductal hypertension. The resectional and resection-draining operations, which were performed in 57.14% of patients, have had constituted the method of choice in the treatment of pancreatic pseudocysts.

[Application of somatulin in the treatment of complications after operations on the pancreatic gland].

The results of treatment of 32 patients with complications, occurring after operations on pancreatic gland, ended by the external pancreatic fistula formation, in the complex of their treatment Somatulin, somatostatin analogue of prolonged action, were studied. Application of the treatment tactics proposed have permitted to achieve the fistula closure in all the patients without the operative intervention. The terms of the pancreatic fistula closure after Somatulin injection had constituted 5-20 days, (11.1 +/- 0.7) days at average.

[Enzyme immunoassay of human chorionic beta-gonadotropin in biological fluids using photographic detection]. / Immunofermentnyi metod opredeleniia beta-khorionicheskogo gonadotropina cheloveka v biologicheskikh zhidkostiakh s ispol'zovaniem fotograficheskoi detektsii.

Potentialities of a new detection method making use of photographic information transformers were demonstrated as exemplified by enzyme immunoassay of human chorionic beta-gonadotropin. Commercial enzyme immunoassay kits for measurements of human chorionic beta-gonadotropin manufactured by Diaplus joint venture were used in the study. The results of traditional spectrophotometric detection and photographic detection were in good correlation, the correlation coefficient r being equal to 0.882. The sensitivity of the method permits reliable testing of clinically significant gonadotropin concentrations in biologic fluids.
