Would you operate on a 85 yr man with chf, for tumor w/cancer in sigmoid colon, 80 pd weight loss, bad ekg too, worried he won't make it, what chance?

Complicated Question: There's not enough space in this forum to answer a complex question like this. There are many nuances... how bad is the CHF? (ie, What is the NYHA Stage? What is the EF?) How large / problematic is the cancer? What type of cancer? (adenocarcinoma,? squamous?) What is the Grade and Stage of the cancer? (They're not the same thing). Hopefully a surgical oncologist is helping guide the pt. I feel 4u. ...Read more

What is malignant neoplasm in rectum? Is that still called colon cancer?

I recently had my appendix out & was told I have diverticula in my sigmoid colon. How dangerous is this?

I recently had my appendix out & was told I have diverticula in my sigmoid colon. How dangerous is this?

Diverticula: Most americans have diverticula, little outpouchings in the colon wall. They rarely cause problems but can get infected, diverticulitis, or cause significant lower GI bleeding. However, most of us do not develop these. The best thing for you to do is eat a high fiber diet and try to prevent constipation. However, in reality we do not recommend avoiding any particular food to prevent problems. ...Read more

Why could my doc not easily remove a 1/2 inch sessile polyp on the sigmoid colon? What type of doc can do it?

Sessile = flat: Sessile polyps are flat, which makes it very difficult (but not impossible) to remove. However, they can usually be biopsied to determine if (pre)cancerous or not. This is where the gastroenterologist comes in handy. Realistically, it comes down to experience as newly minted docs may not have skills of seasoned ones. But in general, gastroenterologist is specialist to go to for colonoscopy. ...Read more

Mild diffuse thickening of rectum and sigmoid colon--suggestive of infective-inflammatory colitis, what to do?

CT scan finding: This sounds like a result from a ct scan. Okay to talk with your doc about this result. Depending on your symptoms, age, and history it may not have much meaning. However, it may need further evaluation, colonoscopy, lab tests, if you have lower colon symptoms, blood in stool, weight loss, change in bowels, fever, pain. Be well. ...Read more

CECT whole abdomen with rectal contrast shows mild thickening of mucosal folds in sigmoid colon. Is this finding significant?

CECT whole abdomen with rectal contrast shows mild thickening of mucosal folds in sigmoid colon. Is this finding significant?

Fold thickening: There are numerous causes of fold thickening, including inflammatory, infectious, vascular, and neoplastic. Sometimes the fold thickening seen on CT is not real, a false abnormality due to incomplete bowel dissension. Your doctor, in the context of your entire clinical picture, can best determine how significant it is. Colonoscopy may be useful if you have not had one. ...Read more

Doc found one sessile polyp (half inch) on my sigmoid colon that he couldn't remove. Is the polyp precancerous or more dangerous than others?

What could be the probable diagnosis of a growth at sigmoid colon and rectm junction?

What could be the probable diagnosis of a growth at sigmoid colon and rectm junction?

Growth=Polyp=Tumor: A growth in the colon, also called a polyp, is a tumor or growth of abnormal tissue. They can be benign (non-cancerous) or cancer. Benign polyps such as adenomas have potential to turn to cancer if they grow a long time. Other polyps, such as hyperplastic, usually don't turn to cancer. Some polyps may already have cancer in them. Colonoscopy with biopsy is usually needed to make a diagnosis. ...Read more

What does "sigmoid colon showed an ulcero-proliferative" mean?

Your doctor can expl: The doctor who gave you this report must explain it to you, if you ask.

This may be a benign polyp, yet you need to get it removed as anything which is proliferating can turn into a cancer if you leave it alone inside for too long. ...Read more

What does equivocal wall thickening of sigmoid colon and proximal rectum mean?

What that means is there may be evidence of inflamed tissue when the wall of the colon is measured but a normal colon is sometimes the same thickness. Most likely further tests will be needed, such as a colonoscopy. That will be a decision made by you doctor based on the clinical situation. ...Read more

What does it mean when there's an area of mild congested mucosa in recto-sigmoid colon?

Mucosal congestion: This means that there is some swelling and inflammation that is going on - kind of similar to what is going on in your sinuses when you're having a cold. I would not worry too much over that if it is the only thing found to be abnormal. The doc who discovered should be able to help you treating it if it is what is causing your symptoms. In most cases, it would be expected to be asymptomatic. ...Read more

If someone had no waste in his sigmoid colon and then he went out to play a game baseball, would playing baseball cause waste to form in the sigmoid?

No: Waste comes from the food that you put in your mouth, goes to your stomach, then your small bowel, then your colon. If your sigmoid is empty now, it will be full in a few hours from what you had for breakfast, lunch or dinner. The journey from your mouth to your colon takes several hours. ...Read more

If I poop out all I could before I went on a bike ride. After I finished cycling, would there be any waste formed in sigmoid colon from riding?

Possibly: Partly depends on how much food you had eaten the night before and how fast your intestinal transit time is. Your body is constantly forming stool (liquid form on the right side of the colon and more solid by the time it reaches the sigmoid). So even with a good bm in the morning, there could be some stool in your sigmoid by the end of your bike ride. ...Read more
