[Experience in the diagnosis and treatment of cancer of the rectum].

The results of diagnosis and treatment of rectal cancer in 92 patients are analysed. Four clinical forms of rectal cancer were differentiated: with predominant local signs, with predominant general symptoms, with an asymptomatic course and with signs of functional disorders in pelvic organs. In these cases dyselectrolitemia, manifested in hyponatriemia, hypokaliemia and hypochloremia, was noted. According to phase analysis data of the cardiac activity in these patients the myocardial contractility is diminished. Abdomino-anal resection of the obturatory apparatus of the sigmoid is felt to be the operation of choice in rectal cancer, if permitted by tumor localization, its size and anatomical features of the sigmoid.
