title: [Endoscopic diagnostic errors in colon cancer].
abstract: The results of colonoscopy in 567 patients with malignant tumors of the colon have shown that in 10,0% of cases there were errors in primary endoscopic diagnosis due to inferior examination of the colon, missing of malignant tumors, misinterpretation of the alterations revealed. The authors believe that a single endoscopic examination can not be considered decisive, especially when tumor had been clinically or roentgenologically suspected. Only repeated dynamic observations during 12-14 months with 1-3 month intervals can give final conclusions. The authors believe the thorough early analysis, knowledge of endoscopic symptoms, correct estimation of the data of colonoscopy and biopsy to allow avoiding serious diagnostic errors in future.
