BACKGROUND & AIMS: No studies correlate manometric measurements with morphological changes during the esophageal peristaltic sequence. The aim of this study was to develop and use a system for sonographically imaging the esophageal wall while simultaneously recording esophageal pressure changes.
An ultrasonography transducer attached to a manometric probe was used to evaluate the esophagus.
Four sonographic phases of an esophageal peristaltic sequence were identified. The esophageal lumen was not open at rest in phase 1 (resting), increased to a maximum mean circumference of 4.90 +/- 0.57 cm in phase 2 (passive distention), and returned to a closed position in phases 3 (contraction) and 4 (relaxation). The muscle layers of the esophageal wall were baseline resting width in phase 1, decreased in width during phase 2, increased and reached maximum mean widths during phase 3, and returned to baseline widths during phase 4. The measurement of esophageal intraluminal pressure remained at a baseline resting level during phases 1 and 2, increased to a maximum mean peak of 67.95 +/- 9.18 mm Hg during phase 3, and returned to baseline during phase 4.
A combined ultrasonography transducer/manometry probe was used to dynamically and simultaneously evaluate esophageal wall motion, muscle thickness, and esophageal pressure changes during peristalsis.
尚无研究将食管蠕动序列中的测压测量结果与形态学变化相关联。本研究的目的是开发并使用一种系统，在超声成像食管壁的同时记录食管压力变化。
使用附着在测压探头上的超声换能器评估食管。
确定了食管蠕动序列的四个超声阶段。在第1阶段（静息期）食管腔在静息时未开放，在第2阶段（被动扩张期）增加至最大平均周长4.90±0.57厘米，并在第3阶段（收缩期）和第4阶段（松弛期）恢复到闭合位置。食管壁的肌层在第1阶段为基线静息宽度，在第2阶段宽度减小，在第3阶段增加并达到最大平均宽度，在第4阶段恢复到基线宽度。食管腔内压力测量在第1阶段和第2阶段保持在基线静息水平，在第3阶段增加至最大平均峰值67.95±9.18毫米汞柱，并在第4阶段恢复到基线。
联合使用超声换能器/测压探头动态并同时评估食管壁运动、肌肉厚度以及蠕动期间食管压力变化。
