Celioscopy
Celioscopy involves examination of the abdomen through an endoscope. It is passed through an abdominal incision and the peritoneum is examined.
Sigmoidoscopy
Sigmoidoscopy allows the physician to examine the large intestine through the colon. Sigmoidoscopy is used to check for signs of colon cancer. Flexible sigmoidoscopy involves use of a flexible endoscope to screen the inside of the large intestine from the rectum through the last part of the colon. This procedure takes about 20 minutes. A patient scheduled for sigmoidoscopy must follow a liquid diet for about a day beforehand. Possible complications include bleeding and puncture of the colon. This minimally invasive diagnostic test is similar to a colonoscopy.
Enteroscopy
Enteroscopy allows direct visualization of the upper gastrointestinal tract or the bowels. An endoscope is a thin, flexible tube that is inserted into the mouth or nose. In a colonoscopy, the tube is inserted through the rectum to view the small intestine. Enterescopy is used to examine tumors in the small intestine, gastrointestinal bleeding and unexplained diarrhea. Enterescopy can help in identifying conditions such as Crohn's disease, Amyloidosis, Ulcers, polyps and enlarged lymph nodes. Double balloon enteroscopy involves balloons fixed to the end of the tube so as to inflate the small intestine for better examination.
