Abstract
|
|
|
Colonic polyps are one of the most risky factors for colorectal cancer. Colonoscopy permits most colonic polyps to be endoscopically removed and studied pathologically. Experience with 1919 consecutive colonoscopies, from January 1989 to December
1994,
was reviewed to determine their clinical significance. The prevalence of polyp was 9.5%(182/1919). The peak incidence of age was between 5th and 7th decades and male to female ratio was 2 : 1. Anal bleeding was the most common symptom and
pedunculated
polyps were asymptomatic than sessile polyps. Cectum was the most common site. There were 125 cases of sessile polyp and 57 cases of pedunculated polyp. In cases of sessile polyp, colonoscopic removal was performed in 45 cases(84.2%). Eight cases
of
invasive cancer were treated by colectomy and two cases of carcinoma in situ were treted by colonoscopic polypectomy. The most common histological type was adenomatous polyp. Inflammatory and harmatomatous polyp were followed. The malignant rate
of
sessile polyps were 12.8% and pedunculated polyps were 8%.
As a result of this study, it is concluded that total colonoscopic examination must be performed in patients who complaint rectal bleeding and are over 40 of age and if polyps are detected during procedure, colonoscopic polypectomy is
recommended.
