Abstract

Objective To establish real-time surveillance Methods for capsule endoscopy when used in observing upper gastrointestinal mucosal diseases of Beagle dogs or other larger animals.Methods 1.One end of suture 4-0 was tied with the waist of the capsule endoscope, and the other end was taken from the top of the gastric tube through the lumen and out of the tube from a side hole before the capsule endoscope was pulled against the top of the gastric tube by stretching the line to accomplish a simple reconstruction for PillCam SB2 capsule endoscope; 2. A Beagle dog was narcotized before the gastric tube was used to assist the capsule endoscope into the esophagus and gastric cavity; 3. Glacial acetic acid (40%,40 ml)was administrated intragastrically and the capsule endoscope was used to observe the mucosal changes of the digestive tract.Results 1.The modified capsule endoscope entered the Beagle dog’s esophagus and stomach with the help of the gastric tube, and the capsule endoscope could be controlled when it rested against the top of the gastric tube by stretching the line to change the position and angle of the capsule endoscope; 2. Gavage administration of glacial acetic acid (40%,40 ml) led to the establishment of an acute gastric mucosal lesion model for Beagle dogs ; 3. The capsule endoscope could clearly capture the images of the gastric cavity, observe the apparent changes of gastric mucosa at different time points, making possible real-time surveillance of changes of gastrointestinal acute mucosal lesions of the animal model.Conclusions A method of real-time surveillance of the development of upper gastrointestinal mucosa acute lesions by capsule endoscopy has been established, which can be used to observe the changes of gastric mucosal acute injury of beagle dogs or larger animals.
