Study of Two Fasting Procedures Before Gastroscopy: 6 Hours Versus 2 Hours for Clear Fluids

Upper gastrointestinal endoscopy is the key examination for screening for precancerous and cancerous lesions of the esophagus and stomach. This study aims to describe the quality of the visualization of the esophageal and gastric mucosa, the safety of use of two fasting procedures before gastroscopy and the feeling of patients. The population evaluated here concerns cirrhotic patients, at high risk of developing a precancerous lesion of the upper gastrointestinal tract.

The investigator carries out a prospective, monocentric (Besançon CHRU), interventional and randomized study according to two fasting procedures before gastroscopy: 6 hours (F6 group) versus 2 hours (F2 group) for clear fluids. The primary endpoint was to describe and compare the quality of visualization of the esophageal and gastric mucosa, graded from A (good quality) to C (poor quality) according to a score. developed by Elvas et al. (Endoscopy 2017).
