Help please! is air injected into the colon during a colonoscopy?

Help please! is air injected into the colon during a colonoscopy?

Yes: Colonoscopies generally require slight insufflation of air into the colon... This distends it and allows your doctor to look for polyps. This distension may cause some discomfort which is why most patients get sedated for the procedure. Your doctor generally will try to release all the gas at the end of the procedure so you don't feel too bloated! ...Read more

How much of the colon is examined during a colonoscopy?

How much of the colon is examined during a colonoscopy?

All of it!: The intention with colonoscopy is to examine the entire length of the colon. Sometimes due to tortuosity (or twisty-ness), it is difficult or impossible to see the entire colon. Other ways to evaluate the colon include virtual colonoscopy and barium enema. The advantage of colonoscopy is if anything is found, it can be biopsied or removed often times right away. ...Read more

Does the air pumped into the colon also inflate the small intestine?  What part of the intestine is likely to be involved in a inguinal hernia?

Can the cecum be seen during a colonoscopy? Or is it through a sigmoidoscopy? Can cancer of the cecum be detected through radiology tests like ct/mri?

Can the cecum be seen during a colonoscopy? Or is it through a sigmoidoscopy? Can cancer of the cecum be detected through radiology tests like ct/mri?

Yes-No-Maybe: Colonoscopy evaluates the entire large intestine, from cecum to rectum. Flexible sigmoidoscopy only goes as far as the left side of the colon, nowhere near the cecum. Routine ct scanning may identify a (large) cecal tumor but is much less sensitive than a colonoscopy; ct colonography is almost as sensitive as a colonoscopy, but is less desirable than colonoscopy since a biopsy cannot be done. ...Read more

Can endometriosis of the bowel be found during a colonoscopy?

Can endometriosis of the bowel be found during a colonoscopy?

Endometriosis of gut: Most GI doctors consider endometriosis in women with complaints of chronic discomfort. Crampy, nonpelvic pain can be seen in extensive endometriosis, & symptoms do not always intensify prior to or during menses. The disease can mimic inflammatory bowel disease on barium studies. On colonoscopy, submucosal lesions like endometriosis may be polypoid. Endoscopic ultrasound may be of further help. ...Read more

Why do esophageal cancer patients have a feeding tube inserted into the duodenum instead of the stomach?

Why do esophageal cancer patients have a feeding tube inserted into the duodenum instead of the stomach?

To avoid stomach: When your esophagus is removed due to cancer (esophagectomy) in order to eat again, your stomach may be used to replace your esophagus (stomach conduit). Therefore you want to avoid any surgery that may compromise the use of the stomach as a conduit. Therefore a feeding tube would be placed in the small bowel or jejunum. This is called a "j" tube. ...Read more

Is the barium enema exam of the large intestine safe for heart patients?

Is the barium enema exam of the large intestine safe for heart patients?

Compared to what? Ca: Cancer? Any procedure or test comes with risk, so if it isn't needed, then best not to do it. However, whoever ordered the Barium enema did so for a reason & the risk-vs-benefit calculation was done based on symptoms, history, & a preliminary diagnosis. All-in-all, barium is safer than colonoscopy using Mag citrate or other laxatives that cause electrolyte problems & require sedation. Enema is OK. ...Read more

What damage can be done from barium remaining in the esophagus? In sept i had an attempted tif procedure done. However, while inserting the equipment into my esophagus, the physician sliced into my esophagus wall creating a pocket. At the time the physici

A : A tear in the lining of the esophagus will repair itself. It is likely that you were kept from eating to make sure the tear was not deeper, going throught the entire wall of the esophagus leading into the chest between the lungs (the mediastinum). Given that this was in september and you are not extremely sick (or worse), that likely did not happen. Barium remaining in the esophagus should not be problematic. There are many variable to the story you give that can make any answers difficult to give, but the time course you describe leaves me to believe that you do not have a hole in the esophagus. ...Read more

What does "Bowel gas pattern is abnormal with dilated gas-filled small bowel, mostly in the left upper quadrant. Gas is present within the colon" mean?

Xray read: It means that there is a suggestion on plain film of the abdomen that there could be a small bowel obstruction/ partial obstruction or ilieus (temporary paralysis of the bowel). Depends on the clinical situation but that there is gas in the colon is somewhat assuring. Ask the doctor who ordered the film to go over the findings with you. ...Read more

When you get a barium enema, how long or round is piece that is inserted into rectum? I am nervous about the whole procedure!

When you get a barium enema, how long or round  is piece that is inserted into rectum? I am nervous about the whole procedure!

Not Big: I've been the inserter and the insertee. The tip is about as thick as an index finger with a mild area of widening about an inch from the end of the tip. A small balloon may be inflated after the tip is inserted (with lots of lubricant). The balloon helps you keep the enema from leaking out. Only a few inches of the tip will get inserted. Try not to get too worked up. The prep is a bigger deal. ...Read more
