BACKGROUND Endoscopic polypectomy is a common technique, but there are discrepancies over which treatment--surgical or endoscopic--to follow in case of polyps of 2 cm or larger. OBJECTIVES To analyse the efficacy and complications of colonoscopic polypectomy of large colorectal polyps. PATIENTS AND METHODS 147 polypectomies were performed on 142 patients over an eight-year period. The techn...
Traction device to remove an adenoma in the appendiceal orifice by endoscopic submucosal dissection.
appendiceal orifice by endoscopic submucosal dissection Adenomatous polyps of the appendix are rare [1,2]; in some cases polypectomy is unsuccessful and surgical treatment is required [3]. Appendiceal polypectomy at colonoscopy is carried out extremely rarely [4]. This is the first reported case of an adenoma of the appendix resected using a traction device during endoscopy. A 63-year-old man a...
S2907 Duodenal Lipoma Masquerading as an Adenomatous Polyp Causing Intermittent Duodenal Obstruction
from june 1989, to june 1991, 58 patients with gi polyps were reviewed. except two patients who had multiple polyps, 56 had only one polyp. the size of polyps were 0.5 to 3 em in diameter. 51 (75%) of polyps were located in the rectosigmoid region, 25 (37%) were in the rectum and 26 (38%) in the sigmoid. (seventeen) (25%) polyps (two in right colon, four in transverse, and 11 in descending colo...

Arylamine N-acetyltransferase 2 (NAT2) is involved in both the detoxification and bioactivation of carcinogenic arylamines and other mutagens. This enzyme is polymorphic, and the fast and slow phenotypes are thought to be risk factors for colon and bladder cancer, respectively. Here, we report on a case-control study of adenomatous and hyperplastic polyps, with particular attention to tobacco s...
Fermentation of carbohydrates in the colon can stimulate cell proliferation and could thus be a cancer risk. The effects of resistant carbohydrates, i.e. those not digested and absorbed in the small intestine, on cell proliferation, crypt fission and polyp development were investigated in wild-type and adenomatous polyposis coli multiple intestinal neoplasia (Apc(Min/+)) mice. Fifteen 4-week-ol...
