[Standardized enteroclysis. Monitoring of intra-lumen pressure in 3 different patient groups].
OBJECTIVE
Monitoring of intraluminal pressure in standardized enteroclysis.


METHODS
Pressure monitoring with a double-lumen tube during fluoroscopy-guided adjustment of contrast media instillation rate due to small bowel motility and contrast media transport of 67 patients. Stratification according to patient data and findings in enteroclysis: Crohn's disease (n = 12), non-inflammatory disease (n = 35) and irritable bowel syndrome (n = 20).


RESULTS
The amount, instillation period and rate of contrast media and distension media were not statistically different within the study population. Crohn's disease patients showed elevated intraluminal pressure at the end of the distension phase (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 = 0.0002). 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 Crohn's disease require a longer instillation period of distension media (28.05 +/- 12.82 min, not statistically significant).


CONCLUSIONS
Intraluminal pressure differs in standardized enteroclysis with fluoroscopy-guided instillation rate adjustment. Irrespective of stenosis or acute inflammation, patients with Crohn's disease show a higher intraluminal pressure compared to patients with non-inflammatory disease or irritable bowel syndrome.
