ACG: Capsule Colonoscopy Promising for Polyp Detection
Investigational technique not yet approved by the U.S. Food and Drug Administration
WEDNESDAY, Oct. 25 (HealthDay News) -- Capsule colonoscopy, the investigational method to detect colon polyps that involves ingestion of a small video capsule, has shown promise in two studies presented at the 71st Annual Scientific Meeting of the American College of Gastroenterology in Las Vegas.
In the first study, Blair Lewis, M.D., from Mount Sinai School of Medicine in New York City, and colleagues compared the accuracy of colonoscopy, capsule colonoscopy and virtual colonoscopy, to detect polyps and cancer in 51 patients, of whom 16 had family histories of colon cancer. They found 17 polyps in 15 patients, of which 16 were detected by colonoscopy, 12 by capsule colonoscopy and five by virtual colonoscopy.
"Capsule colonoscopy may complement colonoscopy in cases where colonoscopy is contraindicated, in incomplete colonoscopy, and for patients unwilling to undergo standard colonoscopy," Lewis said in a statement.
In the second study, Ramil Eliakim, M.D., from Rambam Medical Center in Haifa, Israel, and colleagues compared capsule colonoscopy and standard colonoscopy to detect polyps. They found that 70 percent of polyps were detected by capsule colonoscopy compared with 80 percent by standard colonoscopy.
"Improvements in the procedure may increase capsule endoscopy completion and polyp detection rates," Eliakim noted in a statement. "Further studies are needed to evaluate capsule endoscopy accuracy in the average risk population."
