[Follow-up of a cohort of 2604 colorectal adenomas treated in 1991 and 1992. Search for parameters related to adenomatous recurrence].

Aim: To evaluate the recurrence of colorectal neoplasia after endoscopic resection of adenomas.

Methods: The establishment of a register of colorectal cancers and pre-cancerous lesions for Loire-Atlantique (a French administrative division) led to the recording of files for all subjects with colorectal adenomas. The files for the cohort followed up for the years 1991 and 1992 were re-examined at the end of 1998 to determine the risk factors for recurrence.
