Question 1

What is the process of sigmoidoscopy with the colon?

Accepted Answer

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.

Question 2

How long does it take for performated colon symptoms to occur after sigmoidoscopy?

Accepted Answer

Depends on the extentbofbpweforation. Could be from a few hours to days. See your doctor if you have fever , or abdominal pain.

Question 3

Can many months of cdif & tx make your colon more likely to perforate from colonoscopy or sigmoidoscopy after its cured (test ok & no sx)?

Accepted Answer

I am not aware of any data to suggest this.

Question 4

If a sigmoidoscopy scope shown no polyps or cancer in the area tested, does that mean there's no cancer throughout all of the colon?

Accepted Answer

A sigmoidoscopy allows viewing of the rectum, sigmoid colon and occasionally the last part of the descending colon. This is about 25% of the colon and leaves 75% of colon unexamined and at theoretical risk for cancer

Question 5

Do colon cancers usually continue to bleed? can they bleed then nothing for 2.5 years? no symptoms, negative sigmoidoscopy.

Accepted Answer

Colon cancers can bleed but they do not regress and go away...They continue to grow and obstruct the large intestine and also spread to the liver within one or two years, if left untreated. Colonoscopy is a better way to locate them as sigmoidoscopy only reaches the lower part of the colon.

Question 6

Would a sigmoidoscopy show details or info like a colonoscopy and a endoscopy ? still have bad stomach symptoms. got a colon and endo done still pain

Accepted Answer

of the colon and specially the sigmoid colon and the anus is generally done to rule  out lesions of the lower colon specially if there is unexplained abdominal pain or rectal bleeding or change in your bowel movements
to rule out lesions like malignancy
I am sure you physician is worried about the status of your colon and will then treat your abdominal pain

Question 7

I jst had my flex sigmoidoscopy. dr saw small ulcer in my colon, her post endoscopic diagnosis is 'colitid probably amebic'. if not amebic, what is it?

Accepted Answer

it could be another infection. it could be due to inflammatory bowel disease (such as crohn's disease or ulcerative colitis), it could be a cancer (unlikely at your age), it could be lack of blood supply to your colon. biopsies should help

Question 8

Does fresh blood mixed with stool come from higher than the sigmoid colon? from what i understand a sigmoidoscopy is a pointless test.?

Accepted Answer

Bright red Blood per your rectum (BRBPR) is never normal and signifies that most likely you have a bleed close to your anus.  A sigmoid scope will only see the distal third of your colon, so most Doctors will opt to simply do a full colonoscopy to see the whole colon and assure that there is no bleeding coming from anywhere else too.

Question 9

Would sigmoidoscopy performed up to the proximal sigmoid colon mean the doctor examined the proximal sigmoid colon or stopped right before reaching it?

Accepted Answer

The report you mentioned used standard language for a complete sigmoidoscopy. The report is telling the reader that the doctor used a sigmoidoscope to look at the colon from anus to rectum up to and including the proximal sigmoid colon. The evaluation stopped before reaching the bottom of the left descending colon.

Question 10

Can diveticulosis (not itis) be mistaken for colon cancer on ct scan?  had sigmoidoscopy to 35 cm and 4 ct scans over past three years.

Accepted Answer

Diverticulosis has quite a different appearance than cancer of the colon and it would be unlikely that the two would be confused by the radiologist if the diverticulosis was straightforward.
