Intraoperative Determination of Intestinal Viability: A Comparison with Transserosal Pulse Oximetry and Histopathological Examination

O2 saturation measures > 76% may indicate reversible changes as mucosal necrosis, transmural congestion, or mucosal hemorrhage, and O2 saturation measures < 64% may indicate permanent transmural necrosis. As a result, intraoperative evaluation of intestinal viability by pulse oximetry may give us an idea about the degree of pathological changes and subsequently might reduce the number of second-look operations.
