Abstract
Colonic EMG has not yet been reported in children.
5 children (3 boys, 2 girls, mean age 5.3 ± 3.4 y) with severe irritable bowel syndrome (IBS) underwent a colonic bipolar EMG with a probe with annular electrodes positionned in left colon by colonoscopy. After an overnight fast, a two hour pre- and post-prandial recording was performed (meal : 30 Kcal/kg).
Results : the tracing showed the typical colonic patterns : Short Spike Bursts (SSB), Long Spike Bursts (LSB), Migrating Long Spike Bursts (MLSB). As in adults, different patterns were observed, associated with different clinical features of IBS :
- in one case with watery diarrhea, low electrical activity with reduced number of SSB during the preprandial period, and a normal postprandial increase of colonic motility.
- in two IBS with abdominal pains, intense preprandial spiking activity with repetitive LSB, and decreased activity after feeding.
- in two cases with alternate diarrhea and constipation the preprandial electrical activity was normal and the postprandial spiking activity was lowered. These preliminary results individualize several groups of IBS children. Colonic EMG may contribute to diagnostic and therapeutic progress in IBS, and other intestinal dysmotilitics in children.
