Investigation of effect of lesser curvature seromyotomy of the stomach in animal experiments

The effectiveness of seromyotomy of the lesser curvature of the stomach — the simplified version of proximal selective vagotomy — was investigated in eleven dogs. Decreased acid secretion was proved with congo red test and pH measuring by glass electrode. No significant damage to the motor function of the stomach was found with scintigraphy. Histological examinations revealed neurofibre degeneration peripherally to the seromyotomy line after peripheral vagotomy and vacuolar degeneration in the ganglion cells and amputation neuromas in the seromyotomy line.
