So why does there seem to be more fuss about colonoscopies vs upper? Is it more to do with the preparation required and the chance of incomplete exam?

So why does there seem to be more fuss about colonoscopies vs upper? Is it more to do with the preparation required and the chance of incomplete exam?

Colonoscopy.: Not sure what you mean by "fuss," but it is true that preparing your colon for a colonoscopy is more difficult than just not eating after midnight to prepare for an upper endoscopy. However, if you take the preparation properly, more than 90% of colonoscopies are completed without difficulty. Just follow the instructions that your doctor gives you and it should go well. Good luck. ...Read more

Well in terms of something going horribly wrong, as small a chance as that might be, is one safer than the other? Colonoscopy vs gastroscopy.

Well in terms of something going horribly wrong, as small a chance as that might be, is one safer than the other? Colonoscopy vs gastroscopy.

Both are very safe: modern colonoscopy and EGD are extremely safe. Complications are rare. Probably the most common complication is perforation, and it reportedly occurs in about one of every 1200 colonoscopies and about one every 2000 upper endoscopies. There are rare risks of bleeding and of a reaction to the sedation. Overall, they are extremely safe, and if you have a reason for needing one, don't shy away. ...Read more

If you have a clean egd and colonoscopy, then what are the chances you could still have chron's?

Still possible: Crohn's disease affects small bowel, primarily. So this part of the GI tract is not accessible via egd or colonoscopy. So the diagnosis is made on clinical basis and barium studies of the small bowel. You can consult a gastroenterologist for further clarification. ...Read more

I am 31 i had my first colonoscopy in february of this year, is there any chance that tumors or polyps can appear soon after? It was negative!

Depends...: Depends on--genetics (is there an underlying polyposis syndrome); the skill of your colonoscopist & the quality of your colon preparation; risk reduction (eat more fiber, less fat, watch your weight); predisposing factors (crohn's colitis, ulcerative colitis), age (incidence of polyps increases with age), more. That being said, a negative exam at age 31 offers opportunity for polyp prevention. ...Read more

If I had a normal colonoscopy 17 months ago but now have a mass, what are the chances that the mass is cancerous?

It really depends: If one does have a history of prior cancer, or inflammatory bowel disease or familial adenomatous polyposis or a strong family history of cancer - the mass has a higher chance of being cancerous. Always assume any new mass is cancerous and seek medical attention promptly. ...Read more

Developed diverticulitis following colonoscopy. First time ever had it. Colon now messed up. Chance of diverticulitis happening again?

Developed diverticulitis following colonoscopy. First time ever had it. Colon now messed up. Chance of diverticulitis happening again?

Close observation: One risk associated with an elective colonoscopy is a perforation. A plain xray of your abdomen when symptoms start after procedure can help diagnose. It would be difficult to tell the difference from diverticulitis. Recurrance risk will also depend on status of diverticular disease. ...Read more

How can I maximize my chance of an effective bowel preparation for my upcoming colonoscopy?

How can I maximize my chance of an effective bowel preparation for my upcoming colonoscopy?

Split prep: There are at least a dozen colonoscopy preps. However, the most effective prep is taken both the night before and the morning of the exam. Also, it is important to drink as much clear liquids as possible the 24 hours before colonoscopy. Avoid sugary drinks which draws water back into the blood stream from the colon. ...Read more
