Causes of the perioperative complications occurrence in 736 elderly and senile patients, operated on for gastric cancer, were studied. It was established that the complications frequency and mortality were depended on the concomitant diseases presence, on the main disease complications, duration and volume of operation as well, but not from their age. The operation performance method and anesthesiological support perfection would permit to widen indications for the radical surgical intervention performance and raise the treatment of patients efficacy.

[Possibilities of x-ray methods in diagnosis of an acute pancreatitis and its local complications].

The ray methods of investigation were applied in 182 patients with an acute pancreatitis (AP). In 28% of patients local complications of AP were revealed: pseudocyst, abscess, pancreatic gland phlegmon, the gastric wall infiltration and ulceration, paracolic infiltrate and colonic obstruction, biliary hypertension, portal hypertension, subcapsular and parenchymatous splenic hematoma.

[Errors in the diagnosis of tumors of the adnexa uteri and the means for their elimination].

Errors are described made in the course of diagnosis of "false" tumors of the uterine appendages of inflammatory genesis. An algorithm is developed of carrying out differential diagnosis between carcinoma of the ovary and "false" tumours of uterine appendages, involving ultrasonic investigation, computerized tomography and direct endolymphatic antibiotic therapy over a long period of time, which measures permitted a more accurate diagnosis to be made, an adequate surgical treatment to be instituted.

[Multifactorial diagnosis and surgical treatment in inflammatory tumors of the uterine adnexa].

In 66 patients with a tubo-ovarian tumor of inflammatory genesis in consequence of hyperdiagnostics in gynaecological compartments of general practice net diagnosis of the ovary cancer was established. Application of complex diagnostic measures, consisting of computing diagnosis tables construction, use of straight prolonged endolymphatic antibacterial therapy, ultrasonic investigation and computer tomography as well allowed to specify the diagnosis and to conduct an adequate surgical treatment.

[Immediate results of surgical treatment of gastric cancer complicated by anemia].

The immediate results of surgical treatment of gastric cancer complicated by anemia in 137 patients are presented. Resectability rate was 66.4%, total postoperative lethality--4.

[Surgical treatment of cancer of the colon and rectum in patients over 70 years of age].

Analysis of the results of surgical treatment of carcinoma of the colon and rectum in 200 patients over 70 years of age provides strong evidence for recommending sphincter-preserving and one-stage operations by methods of surgical interventions suggested by the authors. Postoperative complications occurred in 34% of patients, the mortality was 12%.

[The dynamics of the enzymatic activity of DNA metabolism during the treatment of stomach cancer patients].

The activity of thymidine kinase was found to be distinctly elevated while the activity of thymidine phosphorylase was markedly reduced in the blood serum of patients with gastric cancer. The dynamics of enzymatic activity depended on the form of surgical intervention. In patients undergoing chemotherapy positive effects were observed in those with a high initial activity of thymidine phosphorylase.

[Restoration of intestinal continuity after right-side hemicolectomy].

In restoration of intestinal continuity in 154 patients with colonic cancer, the duplicate end-to-end anastomosis was used. A description of the method is presented.

[Activity of the enzymes of DNA metabolism in the blood of patients with breast cancer].

Age-related changes in the activity of thymidine- and adenosine-metabolizing enzymes were studied in healthy females and those with breast cancer aged 46-70 years. A significant increase in activity of thymidine kinase, adenosine deaminase and 5'-nucleotidase and a decrease in that of thymidine phosphorylase were registered in blood serum of breast cancer patients of all age brackets. Adenosine deaminase activity in blood serum and lymphocytes of breast cancer patients was found to significantly change after surgery.

[Prevention and treatment of necrosis of the downward transposed intestine following abdomino-anal resection of cancer].

The article analyzes an experience with treatment of 83 patients with necrosis of the descended gut after 1128 sphincter-preserving resections of the rectum. The rectum resection if performed at high professional level and the drug correction of coexistent diseases were found to reduce the amount of necroses of the descended gut up to 4%. In 33.

[Surgical treatment of non-epithelial tumors of the stomach].

The results of surgical treatment of 38 patients with non-epithelial gastric tumours are presented. Combined treatment contributes to the increase in the survival of patients.

[Results of surgical treatment of cancer of the large intestine in middle-aged and elderly patients].

The immediate and long-term results of the surgical treatment of cancer of the colon and rectum in 955 elderly and senile patients are presented. The authors recommend the wide use of the primary-restorative operations on the colon, and the sphincter-preserving operations on the rectum. In advanced cancer of the large intestine, the performance of combined and palliative resection, and extirpation of the large intestine is justified.

[The enzymatic activity of DNA metabolism of the blood in patients operated on in stomach cancer].

The study was concerned with comparison of the activity of thymidine kinase, thymidine phosphorylase, adenosine desaminase and AMP 5'-nucleotidase in serum of cancer patients and healthy subjects. A significant change in 5'-nucleotidase level was registered in patients over 60 years of age and in those of adenosine desaminase and thymidine phosphorylase in patients older than 70 years. A comparative evaluation of the activity of those enzymes showed an increase in thymidine kinase activity matched by a sharp drop in that of thymidine phosphorylase in patients over 45 years.

[Surgical treatment of complicated cancer of the rectum].

The authors make an analysis of results of the surgical treatment of 246 patients with rectum carcinoma complicated by partial or complete ileus, pararectal abscess and perforation of the tumor. The data obtained show that primary resection of the tumor especially with a one-step reestablishment of the colon continuity is one of the main prerequisites for the elimination of postoperative complications and lethality.

[Age-related characteristics of thymidine metabolism in healthy subjects and in patients with stomach ulcer and cancer].

Biosynthesis of pyrimidine nucleotides was intensified in proliferating tissues. Age-dependent alterations in activities of thymidine kinase and thymidine phosphorylase were found in healthy persons of 17-70 years old. Distinct increase in activity of thymidine kinase was observed in patients with gastric ulcer but the activity was decreased with ageing.
