Colonoscopy monitoring intervals after polypectomy of adenomas of the large intestine in patients younger than 40 years of age

: A group of patients younger than 40 years of age, who had been subdued to endoscopic large intestine adenoma polypectomy were compared with the rest of the patients regarding the adenoma occurrence according to sex, localisation, histologic character, frequency of recurrence, and carcinoma formation in the large intestine in the site of previous polypectomy. The compared groups of patients differed merely in time of recurrence. In patients over 40 years of age the adenomas reoccurred most frequently in the first and fifth years following the primary polypectomy. In patients after primary polypectomy regular colonoscopic controls were suggested, namely after the first year and subsequently after every two years. This scheme is appropriate also for patients under the age of 40 years. Therefore the recommended intervals of colonoscopic controls at this age category do not require to be subdued to alteration.
