Bilateral trunkal vagotomy (BTV) regarded as a pathogenic process. An experimental study.

Experimentally, bilateral trunkal vagotomy (BTV) generated some early acute modifications represented during the first 14 days by blood stasis, partial thrombosis, inflammatory infiltrates and necrobiosis of the gastric mucosa. The vascular lesions are the first to occur, the tissular ones being secondary. Later on, two and three months after surgery, chronic inflammation and metaplasia of the intestinal type have been detected as well.
