Upper GI endoscopy and colonoscopy simultaneously?

Upper GI endoscopy and colonoscopy simultaneously?

Yes sometimes needed: it can be done at the same time (different scopes!). by performing both, you get anesthesia only once but get two procedures done, minimizing risks of future anesthesias. This is only done if both are medically needed (regardless of physician reimbursement), no need to do them always together. ...Read more

Would an upper GI endoscopy reveal celiac disease?

Would an upper GI endoscopy reveal celiac disease?

Depends: A person would need to be consuming at least some gluten on a daily basis for 3 weeks prior to the studies for a biopsy to obtain tissue consistent with the diagnosis. That could be as little as a slice of wheat bread/day, but someone who has been avoiding gluten can make the study less accurate. Just looking (endoscopy) is not diagnostic. ...Read more

Can upper GI endoscopy show intestinal cancer?

Can upper GI endoscopy show intestinal cancer?

Some areas.: Upper endoscopy can look at the esophagus, stomach, and at least the 1st portion of the duodenum; also the opening where the bile exits. It cannot look at and therefore cannot diagnose problems in the remainder of the duodenum, the ileum or the jejunum. However, capsule endoscopy can look at these other areas. ...Read more

Can normal CT scan, stool and blood tests, colonoscopy, gallblader us and hida scan, upper endoscopy (gerd, gastritis) rule out pancreatic cancer?

Can upper GI endoscopy shows intestinal cancer?

Can upper GI endoscopy shows intestinal cancer?

Sometimes but not: Often. Egd examines esophagus, stomach, duodenum (technically small intestine, but only the very first part), and sometimes the first portion of jejunum, which is the true small intestine. The small intestine is about 30 feet long. Then there is the large intestine, or colon, for which you need colonoscopy. The middle 29+ feet is not accessble via endocsopy. ...Read more

Can an upper endoscopy and a colonoscopy diagnose gastroparesis?

Can an upper endoscopy and a colonoscopy diagnose gastroparesis?

Sometimes: It's actually a clinical diagnosis, based on high level of suspicion (i.e., if you are a diabetic, for example) a "snapshot" (upper endoscopy, aka egd) may show liquid in the stomach after 8-10 hours of fasting; but no fluid does not negate the clinical diagnosis. Plus, many medications can stop evacuation from a healthy stomach. ...Read more

Do colonoscopies screen for colon cancer?

Yes.: That is one of the main reasons for colonoscopy. The gastroenterologist usually can see every part of the colon wall and biopsy suspicious lesions. Often this is curative if found early. While not completely true, consider all polyps to be future cancers and most cancers come from polyps. Screening should begin at age 50 unless there is a history to suggest beginning earlier. ...Read more
