Anorectal Manometry in Defecatory Disorders: A Comparative Analysis of High-resolution Pressure Topography and Waveform Manometry

Comparison of High-resolution Anorectal Manometry With Water-perfused Anorectal Manometry

BACKGROUND/AIMS To date, high-resolution manometry has been used mainly in the study of esophageal motility disorders and has been shown to provide more physiological information than conventional manometry, and is easier to interpret. This study aimed to evaluate the usefulness of high-resolution anorectal manometry (HRARM) compared to water-perfused anorectal manometry. METHODS Patients who...

Anorectal manometry results in defecation disorders.

Anorectal manometry and suction biopsy were carried out on 47 children with constipation or soiling, or both. Patients were divided into two groups. Group 1 (37 patients): functional faecal retention, group 2 (10 patients): functional faecal soiling without retention. Ganglion cells or normal acetylcholinesterase staining, or both, was demonstrated in all cases. Normal inhibition of internal sp...

Minimum standards of anorectal manometry.

Functional disorders of the anus and rectum affect 10–20% of the population. Tests of anorectal function can provide useful information regarding the pathophysiology of disorders that affect continence and defecation or those that cause anorectal pain. Currently, several tests are available for evaluating anorectal function (Table 1). Often, they complement each other, but among the various tes...

Colon high-resolution manometry: using pressure topography plots to evaluate pediatric colon motility.

OBJECTIVES Colon manometry is usually performed using the 8-pressure sensor water-perfused manometry system. High-resolution manometry (HRM), using closely spaced solid-state pressure recording sensors, provides more detailed information of gut luminal pressure changes, and, by displaying the HRM data as a pressure topography plot (PTP), helps with data interpretation. Our aim was to compare th...
