In an open prospective non-selective study intramucosal pH (pHi) was monitored in 27 patients undergoing elective aortic surgery and in seven submitted to emergency procedures. The pHi was monitored in the sigmoid colon in all 34 patients and in the stomach in 26. Eight patients developed major complications, four of whom had ischaemic colitis, and five died. Sigmoid acidosis (pHi below 7\u00b710) served as an early warning; if acidosis was reversed within 2 h no major complication developed, if prolonged it was predictive of major morbidity (sensitivity 100 percent, specificity 92 per cent). A colonic pHi below 6\u00b786 predicted endoscopically detectable ischaemic colitis. A gastric pHi below 7\u00b720 predicted major complications with a sensitivity of 100 per cent and specificity of 81 per cent. Both monitoring procedures were considered feasible, although monitoring in the sigmoid colon was found to be superior for the patients studied.<\/jats:p>","DOI":"10.1002\/bjs.1800810108","type":"journal-article","created":{"date-parts":[[2007,3,3]],"date-time":"2007-03-03T19:24:48Z","timestamp":1172949888000},"page":"25-30","source":"Crossref","is-referenced-by-count":107,"title":["Early detection of major complications after abdominal aortic surgery: Predictive value of sigmoid colon and gastric intramucosal ph monitoring"],"prefix":"10.1093","volume":"81","author":[{"given":"M","family":"Bj\u00f6rck","sequence":"first","affiliation":[{"name":"Vascular Unit, Department of Surgery, University Hospital of Northern Sweden , Ume\u00e5,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B","family":"Hedberg","sequence":"additional","affiliation":[{"name":"Vascular Unit, Department of Surgery, University Hospital of Northern Sweden , Ume\u00e5,","place":["Sweden"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[1994,1,1]]},"reference":[{"key":"2024092813134540500_bib1","doi-asserted-by":"crossref","first-page":"806","DOI":"10.1001\/archsurg.1960.01290220098012","article-title":"Ischemia of the colon as a complication in the surgery of the abdominal aorta","volume":"80","author":"Smith","year":"1960","journal-title":"Arch Surg"},{"key":"2024092813134540500_bib2","first-page":"417","article-title":"Ischemic colitis: incidence following abdominal aortic resection: a prospective study","volume":"80","author":"Ernst","year":"1976","journal-title":"Surgery"},{"key":"2024092813134540500_bib3","doi-asserted-by":"crossref","first-page":"825","DOI":"10.1002\/bjs.1800711105","article-title":"Acute gastrointestinal complications of infrarenal aortic aneurysm repair","volume":"71","author":"Crowson","year":"1984","journal-title":"Br J Surg"},{"key":"2024092813134540500_bib4","first-page":"771","article-title":"A prospective study of clinically and endoscopically documented colonic ischemia in 100 patients undergoing aortic reconstructive surgery with aggressive colonic and direct pelvic revascularization, compared with historic controls","volume":"106","author":"Zelenock","year":"1989","journal-title":"Surgery"},{"key":"2024092813134540500_bib5","first-page":"447","article-title":"Intestinal ischemia complicating abdominal aortic surgery","volume":"109","author":"Brewster","year":"1991","journal-title":"Surgery"},{"key":"2024092813134540500_bib6","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1016\/S0950-821X(05)80203-8","article-title":"Ischaemic disease of the colon and rectum after surgery for abdominal aortic aneurysm.
