[The effect of lesser curve seromyotomy of the stomach in animal experiments]

The authors investigated the efficiency of the seromyotomy of the lesser curvature of the stomach in 11 dogs. Reduction of the acid production was verified by glass electrode pH measuring of the gastric mucosa. Scintigraphic examination showed that the operation did not damage the motor function (motility) of the stomach. The fact of peripheral vagotomy was established by histological examination: degeneration of nerve fibres was detected on the peripheral side of the line of the seromyotomy, vacuolar degeneration was found in the cells of parasympathetic ganglions, and amputation neurinomas were shown in the line of the seromyotomy.
