Full description
This is a comparative, prospective, non randomized, controled, mono-centric study.
Eligible patients: patients planned to undergo an upper gastrointestinal endoscopy or a rectosigmoidoscopy with biopsy in the digestive endoscopy unit of Hôpital Ambroise Paré. For patients accept participating to the study and sign the informed consent, they will be enrolled in the study and the recorded imaging of stomach or rectum will be obtained.
Patient management will not be modified in this study as compared to usual endoscopy procedure. Multispectral endoscopy will only prolong the examination 1 minute in order to obtain the imaging. The study consists of video records of endoscopy with white light and the reflected light projected by the fibre introduced 60 seconds in examined channel. This reflected light will be redirected to a multispectral camera.
The endoscopy examinations will be performed in gastric antrum and cardia when theses sites present abnormal position or contour. The biopsies samples of gastric mucosa will be performed in the antrum or the cardia according to the Guideline of the Société Française d'Endoscopie Digestive.
6 groups of patients will be constituted (included 2 groups of control) as described below and compared posteriorly:
