|An antro-duodenal manometry examination is used to evaluate the motor activity of the small bowel.
Measuring abnormal contractions or abnormal motor patterns in the antrum or the small intestine is helpful to diagnose normal or abnormal small bowel function. Motility disorders as irritable bowel syndrome (IBS or spastic colon), diffuse motor dysfunction can be diagnosed.
Migrating Motor ComplexThe normal Migrating Motor Complex (MMC), the mechanism by which food is processed through the gastrointestinal tract, has a period of about 1.5 hours. It can be divided into 3 phases:
Solar GI, intelligent manometry systemWith the Solar GI antro-duodenal examination software, phase I, II and III and MMC cycles can be recorded. Solid state or water perfusion catheters with 4 to 21 channels can be used.
TMPDBy using the TMPD option of the Solar GI it is possible to monitor the position of the catheter during measurement. TMPD means Trans Mucosal Potential Difference. Electrical signals in the antrum and the duodenum are recorded. The catheter is in the right position if the potential difference reaches a value above a certain level.
