During evacuation, rectoanal pressures and the RAG were greater in the seated than the LL position (<jats:italic>P<\/jats:italic>\u2264.001). The new analysis identified 4 rectoanal pressure patterns. In the seated position, the BET was associated with the pattern (<jats:italic>P<\/jats:italic>=.0001), being prolonged in, respectively, 45%, 15%, 53%, and 0% of patients with minimal change, anal relaxation, paradoxical contraction, and transmission.
