How Far Into Colon Does Sigmoidoscopy Go
I have a severely redundant colon that is also permantly distended by gas, why can stool slowly get through but the gas does not, it goes backwards?
Different processes: Passage of gas is more mechanical process than passage of stool that requires active peristalsis in your colon to pass BM. If you haven't done it, you should have a GI consult for an endoscopic exam for proper diagnosis and management. Use OTC meds for gas and diet modification (avoid beans, cauliflower) in the meantime. ...Read moreSee 1 more doctor answer
Sigmoidoscopy is the use of a flexible fiberoptic camera or specially designed scope to examine the inside of the colon. Because the procedure only examines the left side of the colon (in an area called the sigmoid), it is termed sigmoidoscopy. This is to differentiate it from a colonoscopy, where the entire right and left side of the colon is examined. A sigmoidoscopy ...Read more
Sigmoidoscopy exam: The sigmoid colon is the last bend of the gut before food reaches the rectum. Accordingly, examination of the sigmoid & left colon (hence the name "sigmoidoscopy") involves a flexible tube inserted into the rectum (often under sedation if you wish). The procedure takes only a few minutes & typically requires only a limited preparation. On the other hand, "colonscopy" examines the whole colon. ...Read more
Can many months of cdif & tx make your colon more likely to perforate from colonoscopy or sigmoidoscopy after its cured (test ok & no sx)?

Does fresh blood mixed with stool come from higher than the sigmoid colon? From what I understand a sigmoidoscopy is a pointless test.?
Usually lower.: Bright red blood mixed with an otherwise normal stool usually suggests a lower tract source - hemorrhoid, anal fissure, rectal polyp or cancer. These can be readily observed with just a physical examination and sigmoidoscopy. Not look at the whole colon, a colonoscopy is necessary, a point to which I think you're alluding. ...Read moreSee 1 more doctor answer
