Colonoscopy in Jamaica: a 12-year experience

ABSTRACT

Four hundred and nine colonoscopic examinations were performed in 335 patients over a 12-year period in Jamaica. The main indications were suspected polyps (34 percent), rectal bleeding (22 percent), and suspected carcinoma (11 percent). Total colonoscopy was performed in 33 percent of cases. The ascending colon and hepatic flexure were examined in a further 25 percent, and the transverse colon in another 21 percent. Endoscopic examination of the suspected abnormal area was possible in all cases. In 142 examinations, no abnormality was detected, reflecting a false positive Barium enema in some. Polyps were found in 135 examinations, diverticula in 69 and carcinoma in 13. There were no complications. Colonoscopy was more sensitive and specific than Barium enema. The barium enema findings were incorrect in 91 of 224 examinations (41 percent). Colonoscopy is a safe and accurate procedure which enables improved patient management (AU)
