Capsule Endoscopy to Screen for Small Bowel Neoplasia in Lynch Syndrome

Lynch syndrome (LS), or hereditary nonpolyposis colorectal cancer (HNPCC), is a hereditary disorder characterized by a very high risk of early-onset colorectal and endometrial cancer and an increased risk of other cancers, including cancers of the stomach, ovary, urinary tract, hepatobiliary tract, pancreas and small bowel. This is a national multi-centre study evaluating the yield of small bowel screening using capsule endoscopy (CE) and double balloon enteroscopy (DBE) in Lynch syndrome subjects. The intervention consists of performing a capsule endoscopy procedure at baseline and at 2-year follow-up. In patients with polyps or malignant appearing abnormalities on capsule endoscopy, double balloon enteroscopy will be performed with subsequent endoscopic or surgical removal of neoplastic lesions. The aim of the study is to determine the prevalence and incidence of small bowel neoplasia in Lynch syndrome patients using small bowel CE and DBE.
