Is Endoscopic Mucosal Clipping Useful for Preventing Colonic Manometry Probe Displacement?

Abstract

Goal-To examine whether endoscopic mucosal clipping prevents probe migration.Background-Ambulatory colonic manometry can provide useful pathophysiologic information regarding colonic motor function. However, probe displacement during prolonged recording can be problematic.

Day-to-day reproducibility of prolonged ambulatory colonic manometry in healthy subjects

“…Also, gender,13,32 age,33 sleep pattern,11 stress,3,34 and differences in colonic contents may influence intrinsic activity of the colon 5. Extrinsic factors include sensor localization10,21 and migration,26,27 non-physiological conditions (sedation, prolonged immobilization, stressful laboratory environment, bowel preparation with complete evacuation of stool)16,17 and use of different instrumentation (solid-state manometers vs. perfused tube manometry) 8,9,12…”

“…Once the location of the probe was confirmed by fluoroscopy, the silk thread was released, freeing the probe. Subsequently, a clip-fixing device was introduced through the biopsy channel and the silk sutures located at the tip and at three other sites on the probe were clipped to the colonic mucosa) using mucosal clips (Olympus America Inc, Melville, NY) 26,27. The snare was removed.…”

Clinical utility of colonic manometry in slow transit constipation

“…Once the location was confirmed by fluoroscopy, the silk thread was released, freeing the probe. Next, the probe was clipped to the colonic mucosa using mucosal clips (Olympus America Inc, Melville, NY) . The probe was taped securely to the gluteal region.…”

“…). Clipping the catheter to the colonic mucosa minimizes the risk of becoming dislodged and migrating distally throughout the study . As colonoscopy in children is usually performed under general anesthesia, the potential effect of anesthesia on colon motility becomes significant.…”

“…Clipping the catheter to the colonic mucosa minimizes the risk of becoming dislodged and migrating distally throughout the study. 21 As colonoscopy in children is usually performed under general anesthesia, the potential effect of anesthesia on colon motility becomes significant. It has been suggested that the study can be performed as early as 4 hours after recovering from anesthesia 22 but others have recently reported an important effect of anesthesia on colon motility and study interpretation when the study is performed on the same day of anesthesia.…”
