Role of electrogastrography in detecting motility disorders in children affected by chronic intestinal pseudo-obstruction and Crohn's disease.

摘要

Gastrointestinal motility disorders are frequently found in several pathologies. The aim of this study was to assess, by means of electrogastrography, the presence of gastrointestinal motility abnormalities in children affected by Crohn's disease (CD) or Chronic Intestinal Pseudo-Obstruction (CIPO). Patients and Methods. We studied 34 subjects; 20 control subjects (M = 15, mean age = 10 +/- 3.5 yrs), 8 patients (M = 4, mean age = 18 +/- 7 yrs) with Crohn's disease in a quiescent phase and 6 patients (M = 6, mean age = 10 +/- 3.5 yrs) with Chronic Intestinal Pseudo-Obstruction. Results. Analysis of gastric electrical activity (GEA) parameters demonstrated that in the control group physiological post-prandial changes are represented by an increase of 3 Cycles Per Minute (3 CPM) activity, Period Dominant Power (PDP) and Period Dominant Frequency (PDF) and by the reduction of bradygastria. Crohn patients showed an insignificant increase of 3 CPM and PDP; CIPO patients showed an abnormal variation of 3 CPM,PDP and post-prandial bradygastria. Moreover, CD patients showed a significant difference in post-prandial values of PDP compared to normal subjects. CIPO patients revealed a significant difference in the values of either preprandial PDF with tachygastria or the post-prandial value of 3 CPM, compared to normal subjects. Conclusions. EEG is a non-invasive method to study gut motility related to GEA alterations present in CIPO as well as in CD patients.
