PH of the gastric mucosa after surgical interventions an experimental study.
In 41 dogs the mucosal pH was studied before and after different types of gastric resection. After BI and BII-Schoemaker type of resection a decrease of the slope of the pH-graph and an increase in latency was found. The mean surface of the non-acid area was the most extended in the BII-group, while the same was found for the pH-value of the border zone. Also the reduction of the number of parietal cells was reduced considerably. The changes in the microradioangiographic pattern and the histology of the border zone are discussed in view of the findings concerning the changes in mucosal pH and the histological investigation.
