Colon cancer is the third most common cancer diagnosed in men and women in the United States. It is also the third leading cause of cancer-related death in women and the second leading cause in men. Fortunately, over the last 20 years the death rate for this cancer has been decreasing. There are two primary reasons for this decrease, improvements in therapy and the increase in screening for and removal of colorectal polyps. A colonoscopy is recommended for adults over the age of fifty in the US. It is an examination of the colon performed by a gastroenterologist whereby an endoscope is inserted through the anus and into the colon. Most endoscopes have a camera and a light for visualization of the colon. In order to clearly see within the colon, which is in a naturally collapsed state, air or water is used to inflate the organ. Normally, a tight seal is formed around the scope to retain pressure inside the colon. But in some patients, a tight seal is not possible and is not able to retain the pressure making the procedure difficult to perform. Currently, the standard practice in these occasions is for a technician to use a towel to hold the anus shut.
