STANDARDIZED ENTEROCLYSIS - MONITORING OF INTRALUMINAL PRESSURE IN 3 DIFFERENT GROUPS OF PATIENTS

Purpose: Monitoring of intraluminal pressure in standardized enterocly sis. Material and methods: Pressure monitoring with a double-lumen tub e during fluoroscopy-guided adjustment of contrast media instillation rate due to small bowel motility and contrast media transport of 67 pa tients. Stratification according to patient data and findings in enter oclysis: Crohn's disease (n=12), non-inflammatory disease (n=35) and i rritable bower syndrome (n=20). Results: The a mount, instillation per iod and rate of contrast media and distension media were not statistic ally different within the study population. Crohn's disease patients s howed elevated intraluminal pressure at the end of the distension phas e (47.94+/-10.42 cm H2O versus 38.03+/-10.08 and 39.55+/-9.74 cm H2O, respectively, P=0.0099), as well as at the end of the examination (48. 59+/-10.42 cm H2O versus 39.66+/-6.52 and 35.67+/-8.28 cm H2O, P=0.000 2). In comparison with both other patient groups, maximum intraluminal pressure in Crohn's disease is higher and totals 51.75+/-9.94 cm H2O versus 43.00+/-6.20 and 39.55+/-9.74 cm H2O, P=0.0010. Patients with C rohn's disease require a longer instillation period of distension medi a (28.05+/-12.82 min, not statistically significant). Conclusion: Intr aluminal pressure differs in standardized enteroclysis with fluoroscop y-guided instillation rate adjustment. Irrespective of stenosis or acu te inflammation, patients with Crohn's disease show a higher intralumi nal pressure compared to patients with non-inflammatory disease or irr itable bowel syndrome.
