Colonoscopy vs sigmoidoscopy: new studies fuel ongoing debate.

Comparing Current Screening Modalities for Colorectal Cancer and Precancerous Lesions: Is Colonoscopy the Method of Choice?

Colorectal cancer (CRC) is the third most common form of cancer and the second leading cause of cancer death in the Western world. Presently, screening tools such as colonoscopy, sigmoidoscopy, fecal occult blood test (FOBT) and computed tomographic colonography (CTC) are available for CRC screening. The debate over which screening tool is most effective in detecting CRC and precancerous lesion...

Right Colonoscopy vs Sigmoidoscopy Screening : Getting It

Systematic review: the use of nitrous oxide gas for lower gastrointestinal endoscopy.

BACKGROUND Nitrous oxide gas (N(2)O) has been proposed as an alternative to intravenous (i.v.) analgesia in patients undergoing lower gastrointestinal endoscopy. AIM To perform a systematic review of randomized studies where N(2)O was compared against control in patients undergoing either flexible sigmoidoscopy or colonoscopy. METHODS Electronic databases were searched; reference lists were...

Prospective comparison of double contrast barium enema plus flexible sigmoidoscopy v colonoscopy in rectal bleeding: barium enema v colonoscopy in rectal bleeding.

Rectal bleeding often heralds serious colonic disease. The literature suggests that colonoscopy is superior to barium enema plus sigmoidoscopy, although no good comparative studies exist. Seventy one patients with overt rectal bleeding had prospectively flexible sigmoidoscopy, double contrast barium enema and colonoscopy completed independently. Against the gold standard, the sensitivity and sp...
