The aim of this study was to determine changes in the sigmoid colon during and after abdominal aortic grafting using endoluminal pulse oximetry (SmO<jats:sub>2<\/jats:sub>). Oxygen saturation was measured on the mucosa (SmO<jats:sub>2<\/jats:sub>) and serosa (SsO<jats:sub>2<\/jats:sub>) of 20 sequential patients undergoing elective surgery for abdominal aortic aneurysm; intramural pH<jats:sub>1<\/jats:sub> was also measured. Initially, all patients had a normal SmO<jats:sub>2<\/jats:sub> in the sigmoid; however, before cross-clamping eight patients had a reduction in the SmO<jats:sub>2<\/jats:sub>. The pulse curve disappeared immediately after cross-clamping in 15 patients, with only five still showing a pulse curve in the sigmoid colon. Before declamping, 13 patients regained their pulse curve. The intraluminal pH<jats:sub>i<\/jats:sub> showed a large interindividual variation (2 S.D. \u2248 0.4). Patients were classified into three groups according to SmO<jats:sub>2<\/jats:sub>: group A, no pulse; group B, diminished saturation (&lt;90%); and group C, normal saturation (\u226590%). There was significant correlation with the pH<jats:sub>i<\/jats:sub> after cross-clamping in all groups. One patient who developed ischaemia of the sigmoid colon demonstrated a prolonged reduction in the SmO<jats:sub>2<\/jats:sub>, a decreased perioperative pH<jats:sub>i<\/jats:sub>, and an increased oxygen saturation in the inferior mesenteric vein during cross-clamping. <\/jats:p>","DOI":"10.1177\/096721099700500112","type":"journal-article","created":{"date-parts":[[2024,9,24]],"date-time":"2024-09-24T09:11:46Z","timestamp":1727169106000},"page":"65-70","source":"Crossref","is-referenced-by-count":1,"title":["Endoluminal Pulse Oximetry Combined with Tonometry to Monitor the Perfusion of the Sigmoid during and after Resection of Abdominal Aortic Aneurysm"],"prefix":"10.1177","volume":"5","author":[{"given":"A.
