This new oximeter was applied to various organ parts during surgery for a variety of pathologic conditions. There were 10 esophageal cancers, 6 esophageal varices, 13 gastric cancers, 2 gastric ulcers 3 colon cancers, one jejuna! myoma, and one thyroid cancer, the latter with invasion into the cervical portion of the esophagus.
The average tissue SaO2 of the esophagus, stomach, jejumum and colon ranged from 92.3-94.4% at the time of the thoracotomy or laparotomy. In contrast, SaO2 of the liver was low, measuring 59.9%.
Subsequently, the tissue SaO2 of many digestive system organs, whose blood vessels were severed during their surgical removal, was measured. Interestingly, SaO2 of the proximal protion of the upper thoracic esophagus, whose only blood supply was through gastric circulation, still retained 85% saturation at the termination of the intra-thoracic procedure for the resection of the esophageal cancer. Secondly SaO2 of the left lobe of the liver (56%) dropped immediately following ligation of the common hepatic artery (down to 48.5%), but improved in a few minutes (to 55.5%) during Appleby's procedure for a total gastrectomy.
