Sigmoidoscopy
 
 

Ths sigmoid colon is the region of the large intestine close to the rectum. Sigmoidscopy uses a scope to see this area. The scope is a flexible tube with a camera that is inserted through the anus. This procedure is done to take a tissue sample for analysis or look for cancerous polyps or growths. It can also help determine the source of abdominal pain, diarrhea, constipation, changes of bowel habits or the appearance of blood, mucus or pus in the stool. Sigmoidscopies are also done when an individual has unexplained weight loss.
