Advances in fiberoptic endoscopy have improved diagnostic capabilities and management in patients with gastrointestinal polyps. The gastrointestinal polyp is a premalignant lesion in varying degrees, according to size, pathology, and location.
Endoscopic polypectomy has long been considered as a safe and effective method for removal of polyps. Sixty endoscopic gastrointestinal polypectomies were done in 53 patients who visited Hanyang University Hospital from 1984 to 1990, and the
clinical
characteristics including histopathology were evaluated.
@ES The results obtained were as follows;
@EN 1) Most patients were in fifth decade. The ratio of male to female was 1:1.52
2) 40 gastric polyps were found among 41,300 gastrofiberscopies (0.09%) and 20 colonic polyps were found among 1,200 colonofiberscopies(1.6%).
3) The removed gastroduodenal polyps were mostly below 0.5cm in size(37.5%) and colonic polyps were mostly 1.0cm to 2.0cm in size(25%).
4) The number of single polyp was 32(88%) in gastroduodenum and 12(70.5%) in colon. The gastroduodenal polyps, polyps were located on gastric body(20 cases), gastric antrum(18 cases), and duodenal bulb(2 cases), in order of frequency. In colonic
polyps, polyps were located on sigmoid colon(10 cases) and rectum(4 cases).
5) Histopathologic examinations revealed that most common type was hyperplastic type(62.5%) in gastroduodenal polyps and adenomatous type(40%) in colonic polyps. One case of gastroduodenal polyp and three cases of colonic polyps showed focally
malignant change of muscosa.
Therefore, endoscopic polypectomy is thought to be important to assess malignant change of gastrointestinal polyps.
