However—since its development by Dr. Hiromi Shinya and Dr. William I. Wolff in the 1960s—polypectomy has become a routine part of colonoscopy, allowing for quick and simple removal of polyps without invasive surgery.
During a routine colonoscopy, doctors found a cancerous growth attached to Zell's colon, and removed it laparoscopically at Petaluma Valley Hospital.
Virtual colonoscopy (VC, also called CT Colonography or CT Pneumocolon) is a medical imaging procedure which uses x-rays and computers to produce two- and three-dimensional images of the colon (large intestine) from the lowest part, the rectum, all the way to the lower end of the small intestine and display them on a screen.
