Sigmoidoscopy
Sigmoidoscopy is a procedure used to examine the lower part of the large intestine (sigmoid colon and rectum) using a thin, flexible tube with a camera.
It is a quick and minimally invasive test that helps identify problems in the lower colon, especially in patients with symptoms like rectal bleeding, constipation, or diarrhea.
Compared to a colonoscopy, sigmoidoscopy examines only the last portion of the colon, making it faster and simpler.
