title: Chronic splanchnic ischaemia: is tonometry a useful test?
abstract: OBJECTIVE
  To find out if gastric tonometry is of sufficient accuracy to diagnose chronic splanchnic syndrome.
  
  
  METHODS
  Prospective open study.
  
  
  METHODS
  University hospital, The Netherlands.
  
  
  METHODS
  10 patients in whom chronic splanchnic syndrome had been suspected, and in 5 of whom it was subsequently confirmed.
  
  
  METHODS
  Standardised measurement of intramucosal gastric pH (tonometry) and multiplane angiography of the abdominal aorta and splanchnic arteries.
  
  
  METHODS
  Correlation between intramucosal gastric pH and angiographic and clinical findings.
  
  
  RESULTS
  The mean basal pH preoperatively was 7.48 among 5 patients subsequently found to have splanchnic syndrome (group 1) and 7.41 among the 5 who did not (group 2). Those in group 1 all had extensive three vessel disease with stenoses of 70% or more in at least two of the three splanchnic arteries. The 5 patients in group 2 had no clinically important stenoses in either the coeliac or the superior mesenteric artery; 4 had occlusions of the inferior mesenteric artery.
  
  
  CONCLUSIONS
  Gastric tonometry is of no use in the diagnosis of chronic splanchnic syndrome.
