Editor’s note: This is the third in a series of columns by Mary Horsley about IBD-related procedures. Part one and part two are also available. Continuing with my "Scope Series" theme, the next procedure I am writing about is a "double balloon endoscopy." To give you a little insight as to what the procedure entails, it is a more specific-type endoscopy, complete with anesthesia and preparation, as previously discussed for these scopes. Like other scopes, the endoscopy or colonoscopy, the dreaded food fasting is required. This is almost always required because food and waste block the scope view, and items in the bowel can be misdiagnosed as something worse.
