Standard colonoscopy more effective than full-spectrum endoscopy — 3 insights

Research published in the Journal of Clinical Gastroenterology compared full-spectrum endoscopy to standard-forward viewing colonoscopy.

Researchers conducted a prospective, randomized study of 249 patients with positive fecal occult blood tests. Patients either received a standard forward-viewing colonoscopy or a full-spectrum colonoscopy with a full-spectrum endoscope.

What they found:

1. Full-spectrum endoscopes did not detect a significantly higher amount of adenomas than standard forward-viewing colonoscopy.

2. Full-spectrum endoscopes also had a significantly longer insertion time.

3. Researchers also found no significant difference in polyp/adenoma detection rates by lesion size or colonic section.

Researchers concluded, "[Full-spectrum endoscopes] did not detect significantly more colorectal neoplasia than forward viewing colonoscopy in a medium-risk colorectal cancer screening population with positive fecal occult blood test."
