[Gastric ulcers in liver cirrhosis and their exposure to low-intensity infrared laser radiation].
By means of light, scanning electron microscopy and planimetry, the pathomorphology of gastric ulcers (GU) was investigated in patients who had died from liver cirrhosis (LC) and in rats with experimental portal hypertension (PH). It was noticed that GU are frequent (13.3%) in patients with LC. Experimental GU induced in rats with PH persist longer and their areas are larger than in ulcers without cirrhosis. The treatment of ulcers through abdominal wall with low-intensive infrared laser irradiation (LILR) causes significant acceleration of their epithelialization in the rat without cirrhosis. Ulcers in the animals with cirrhosis do not repair under LILR influence, but their area significantly decreases after forming collateral shunting. The congestion in the portal system is the main pathogenetic element in gastroesophageal ulcerogenesis. The laser therapy without decreasing portal hypertension is not efficient.
