| Endoscopy and manometry did not help to elucidate the cause. |
| Finally, a different technology relies on catheters with several miniaturized solid state transducers as an alternative to the conventional manometry equipment. |
| Two other cases with Hirschsprung's disease were examined by manometry. |
| Esophageal manometry generally is used to accurately place ambulatory pH monitoring probes, although adequate placement recently has been reported with a tubeless system. |
| An esophageal manometry revealed a normal function of the upper and lower esophageal sphincters. |
| Anorectal manometry is indicated to demonstrate the rectoanal inhibitory reflex and to rule out Hirschsprung's disease. |
