  • Abstract
  • Look Inside

 Eight lesions of early carcinama of the right colon (cecum and ascending colon) were encountered in six patients during the last two decades in our department. All lesions were resected by operation. Four of these early carcinoma were limited to the mucosa and others had submucosal invasion. Two of four lesions without submucosal invasion were less than 20mm in size, but none of four sm carcinoma were under 20mm in size. The shapes of these lesions were all non-pedunculated but there was one lesion of type Ip.

 Preoperative diagnosis of these lesions were not sufficient. Only three of these eight lesions were detected by x-ray examination, six of the eight by colonofiberscopy. One of the reasons for the bad results of x-ray diagnosis was due to the unusual shapes of these lesions, i. e. two IIa type, one IIa + IIc type, and one IIb type. The poor technique of x-ray examination in the right colon, however, is thought to be the main reason. It is possible to say colonofiberscopy is a more reliable procedure in finding out early carcinoma in the right colon. It should be noted, however, that there was a lesion that was completely missed even by this reliable diagnostic method.
