 We analyzed 99 followed-up cases,105 lesions, of protruded (sessile and/or subpedunculated) type colorectal adenomas less than 10 mm in diameter, all of which were diagnosed as adenoma from biopsy specimen at the initial endoscopic examination. The result were as follows:

 (1) The lesions did not showed marked change in size and shape during the observation period (four years and one month in average). In most of the enlarged cases, the growth of lesion was limited within 2 to 3 mm.

 (2) As histological diagnosis between adenoma and carcinoma has not definitely established yet, protruded type colorectal adenomas measuring less than 10 mm should be followed up for some period, and treatment including polypectomy should be considered when they show dimensional or morphological change.

 (3) From the result of this study, we assume decrease of colorectal carcinomas could not be much expected through increase of polypectomy for those type adenomas.
