  • Abstract
  • Look Inside

 Radiographic diagnosis of multiple cancers of the large bowel was studied over a period of 15 years from 1984 to 1999. It was based on 309 cases. In synchronous cases, the accuracy of preoperative diagnosis was 75.3% by barium enema study alone, and 93.3% by colonoscopy alone, while the rate was 98.9% when colonoscopy and barium-enema study were combined. The cause and problems associated with the lower level of detection by barium enema study were summarized as follows: 1) The most common macroscopic type of missed lesions were nonpedunculated lesions. 2) The lesions were common in the right colon. 3) The size of missed lesions were 10 mm or less. 4) Misjudgment. 5) Malignant obstruction hinders radiographic visualization of the more proximal bowel.

 In order to obtain a more thorough diagnosis when a cancer is first found, careful preoperative examination should be carried out and all patients who have undergone resection of colon cancer should be carefully followed up at short intervals with examination including barium-enema study as well as colonoscopy.
