Basing on the material of 124 patients operated on for cancer of the upper part of the alimentary canal the authors carried out examinations of anastomoses using various visualizing techniques in order to detect cancer recurrences. Oral biocontrast examination using various contrast media proved most efficient. It visualised early changes in the mucous membrane of the stump or anastomosis and determined the degree of flexibility of the walls. USG and CT, however, revealed the depth of wall infiltration and first of all, localisation of distant metastases in lymph nodes, especially in the liver.
