No surveillance is recommended after radical excision of low-risk adenomas (pedunculated adenoma irrespective of size, sessile adenoma < or = 10 mm, number < or = 2. An endoscopic check-up is recommended 3-6 months after radical excision of high-risk adenomas (sessile adenoma > 10 mm, number > or = 3), as well as after excision of a pedunculated or a sessile adenoma with an unclear resection margin. All above is irrespective of histopathological adenoma classification. An endoscopic check-up is recommended 3 months after radical excision of a highly or moderately differentiated malignant polyp with no sign of invasion into blood or lymph vessels and with a maximum invasion depth stage T1-sm1. Surgical resection is necessary if the malignant polyp is poorly differentiated, and/or invades into blood or lymph vessels, and/or is stage T1-sm3, or is excised with unclear resection margins. Treatment for stage T1-sm2 polyps may be individualized. Individuals with low-risk adenomas and a first degree relative with colorectal cancer, individuals having high-risk adenomas or malignant polyps removed, as well as individuals operated on for colorectal cancer should be subjected to colonoscopy after three years and then every fifth year when < or = 75 years of age.
