title: Semicontinuous intra-abdominal pressure measurement using an intragastric Compliance catheter.
abstract: OBJECTIVE
  To compare intra-abdominal pressure (IAP) measurements obtained from an intragastric Compliance catheter with the pressure measured directly in the abdominal cavity.
  
  
  METHODS
  Prospective cohort study in an operating room of the Ghent University Hospital
  
  
  METHODS
  Seven patients undergoing elective laparoscopic cholecystectomy.
  
  
  METHODS
  IAP was obtained from both an intragastric catheter and directly from the peritoneal cavity at 1-minute intervals in patients undergoing elective cholecystectomy and compared using Bland-Altman analysis.
  
  
  RESULTS
  In 156 paired measurements obtained from 7 patients the mean difference between IAPgastric and IAPref was 0.12+/-0.70 mmHg (95% CI 0.01-0.23).
  
  
  CONCLUSIONS
  IAP measured using an intragastric Compliance catheter reliably reflects the reference IAP in patients undergoing laparoscopic cholecystectomy.
