Sessile polyps simply mean that the mass is flat and does not have a stalk. The other types of colonic polyps are pedunculated- these are not flat but attached to a stalk. Since a sessile colonic polyp does not have a stalk, it is usually found very close to the colonic wall lining.
Most benign sessile colon polyps can be removed colonoscopically from all reaches of the colon, thus avoiding laparotomy previously required for most of these lesions. Two hundred and fifty colonoscopy procedures were reviewed, revealing 87 sessile colon polyps ranging from 0.5-6.0 cm. in size.ost benign sessile colon polyps can be removed colonoscopically from all reaches of the colon, thus avoiding laparotomy previously required for most of these lesions.
