Simple gastroscopy technique in the rat.
We present a simple method for gastroscopy in the anesthetized rat using an implanted gastric cannula, a standard rigid arthroscope, and a newly designed valve system. The method allows high-quality endoscopy and photo documentation, large-size biopsies, electrocoagulation and fluid collection. Repeated gastroscopy in the same animal is easy and well tolerated.
