Poor primary peristalsis
WebJun 5, 2016 · This test reveals loss of primary peristalsis in the distal two thirds of the esophagus. In the upright position, there is poor emptying, with retained food and saliva often producing a heterogeneous air-fluid level at the top of the barium column. The esophagus may be dilated (Fig. 72-21). WebUnlike contraction in the skeletal muscles controlled by central sequential activation of motor neurons, primary peristalsis along the smooth muscle portion (approximate distal two-thirds) of the esophageal body is initiated by non-sequential simultaneous central activation, and is believed to be propagated largely by peripheral mechanisms to produce …
