Capsule endoscopy in the detection of small bowel neoplasias in patients with Lynch syndrome

Interventions: Capsule endoscopy will be performed according with standard method:
Small bowel preparation with 2 liters of polyethylene glycol (PEG) preparation. At 5 PM on the evening prior to capsule endoscopy patients will begin drinking an 8-ounce glass of the preparation fluid (in the gallon container) every fifteen minutes until all of the liquid is consumed;
Overnight fast;
Capsule endoscopy (Mirocam) will be swallowed in the day of the exam and pictures will be taken for 12 h and collected in a recorder. The capsule is eliminated in the feces and does not need to be recovered.
The images are read in the appropriate software by an experienced physician.
Primary outcome(s): To access the prevalence of small bowel neoplasias in patients with Lynch syndrome using capsule endoscopy findings.
Patients with relevant findings at capsule endoscopy- tumours or polyps, will be submitted to upper GI endoscopy or double ballon enetroscopy for histological confirmation.[At the time that capsule endoscopy is performed]
