Improving the utility of high-resolution manometry for the diagnosis of defecatory disorders in women with chronic constipation.

ABSTRACT:

Background

We compared the utility of existing and modified versions of high-resolution manometry for diagnosing defecatory disorders (DD).

Methods

In 64 healthy and 136 constipated women, we compared left lateral (LL) and seated manometry, and analyzed with existing (ManoView™) and new methods, for discriminating between constipated patients with normal and prolonged rectal balloon expulsion time (BET). In both positions, the rectoanal gradient (RAG) and, for the new analysis, the pressure topography pattern during evacuation were used to discriminate between constipated patients without and with DD.

Key results

The BET was prolonged, suggestive of a DD, in 52 patients (38%). During evacuation, rectoanal pressures and the RAG were greater in the seated than the LL po
