The largest use of endoscopic techniques is in the examination of the gastrointestinal tract. Upper intestinal endoscopy is the examination of the esophagus, stomach, and proximal duodenum. Colonoscopy is the examination of the colon, large intestine, and in some cases the distal parts of the small intestine. Cholangiopancreatography is the examination of the biUary tree and pancreas.

Endoscopic approaches are typically used and may include colonoscopy, proctosigmoidoscopy, or possibly upper GI endoscopy in patients with suspected CD. Endoscopy is useful for determining the disease distribution, pattern and depth of inflammation, and to obtain mucosal biopsy specimens. Supplemental information from imaging procedures, such as computed tomography (CT), abdominal x-ray, abdominal ultrasound, or intestinal barium studies may provide evidence of complications such as obstruction, abscess, perforation, or colonic dilation.3...

Colonoscopy allows visualization and biopsy of the colon and is preferred if blood has been found in the stool or if the patient has AIDS. 

Barium enema, sigmoidoscopy, or colonoscopy maybe indicated in the presence of red flag symptoms (fever, weight loss, bleeding, and anemia, which maybe accompanied by persistent severe pain), which often point to a potentially serious non-IBS problem. A barium enema may identify polyps, diverticulosis,... 

Flexible sigmoidoscopy can be performed to identify obstruction in the rectum and lower colon, whereas colonoscopy can evaluate the entire colon for organic disease. 

Routinely assess acromegaly complications, including blood pressure, glucose tolerance, fasting lipid profile, cardiac evaluations (if clinically indicated), colonoscopy, dual-energy x-ray absorptiometry (DEXA) scan (hypogonadal only), evaluation of residual pituitary function, and evaluation of sleep apnea. 

In selected patients, sigmoidoscopy, colonoscopy, or abdominal computed tomographic (CT) scan can provide useful diagnostic information. 

Follow-up in patients with amebiasis should include repeat stools (one to three), colonoscopy (in colitis) or computed tomography (CT, in liver abscess) between days 5 and 7, at the end of the course of therapy, and a month after the end of therapy. 

Subclinical warts Subclinical warts may be identified through colonoscopy, biopsy, acetic acid application, or laboratory serology. However, early treatment has not been linked to a favorable effect during the course of therapy in the index patient or the partner with regard to reduction of the transmission rate. 

Colonoscopy revealed multiple polyps in his transverse colon.

Colonoscopy Visual examination of the colon using a lighted, lens-equipped, flexible tube (colonoscope) inserted into the rectum. 

A series of examinations, including proctoscopy, sigmoidoscopy, colonoscopy, or barium enema, may be necessary to determine the presence of colorectal pathology. 

Secondary prevention is aimed at preventing malignancy in a population that has already manifested an initial disease process. Secondary prevention includes procedures ranging from colonoscopic removal of precan-cerous polyps detected during screening colonoscopy to total colectomy for high-risk individuals (e.g., familial adenomatous polyposis). 

The entire large bowel should be evaluated by colonoscopy or flexible sigmoidoscopy with double-contrast barium enema.

Benzodiazepines have a wide array of clinical uses. In addition to relieving anxiety, they can be used to treat epilepsy, alcohol withdrawal, insomnia, agitation, and perhaps impulsivity. They can also be used as muscle relaxants or to produce conscious sedation during certain medical procedures such as cardiac catheterization and colonoscopy.

Electrocautery procedures A theoretical hazard may exist for patients being treated with lactulose who may undergo electrocautery procedures during proctoscopy or colonoscopy. Accumulation of H2 gas in significant concentration in the presence of...

The diagnosis is made by appropriate combinations of colonoscopy, biopsy and contrast radiology. Disease has to be differentiated from ulcerative colitis (see above) and from infective disease, notably tuberculosis and amoebiasis as well as diverticular disease and cancer. 

The diagnosis is essentially by exclusion of discrete organic disease usually by barium enema and sigmoidoscopy, or colonoscopy.
