[A rational surgical procedure in diffuse polyposis and multiple primary cancer against a background of polyps of the large intestine].

Under examination there were 292 patients. An analysis of results of treatment enabled the authors to conclude that surgical treatment of patients with diffuse polyposis of the colon is the method of choice. The method and volume of operations must be determined according to the involvement of the colon in polyposis, the age and state of the patients.

[The surgical treatment of polyps and early forms of cancer of the large intestine].

The article describes the present-day principles of surgical treatment of polyps and early forms of colorectal carcinoma appearing against their background. The investigation performed has shown that all benign adenomas of the colon can be successfully treated by local dissection. Sessile tumors located on the lower- and middle-ampullar portions of the rectum, are liable to endorectal dissection, in pedicular tumors endoscopic polypectomy is most expedient.

[Features of blood gastrin in patients with colorectal cancer: possible prognostic significance].

Blood-gastrin levels were assayed in 112 cases of colorectal carcinoma. Elevated concentrations of gastrinemia were identified in the patients as compared with healthy controls, on the basis of averaged data. An inverse correlation between hypergastrinemia incidence and stage was observed.
