本文根据11例壁细胞迷走神经切断术术后食管下端括约肌的功能测定,观察此手术对括约肌功能的影响。用特殊的测压系统分别记录食管静止压力、吞咽反应时的压力、食管下端高压带长度以及食管下端括约肌压力升高与胃内压升高的比值。结果显示:手术前后静息时食管下端括约肌的压力(12.7±1.18mmHg与13.7±0.73mmHg)没有明显差异。高压力带的长度(3.85±0.15和3.73±0.17cm)也基本接近。在正常吞咽松弛后的观察也没有任何改变。
In this paper, 11 cases of parietal cell vagotomy after esophageal sphincter function was measured to observe the operation of sphincter function. With a special pressure measurement system were recorded esophageal resting pressure, pressure during swallowing reaction, the lower esophageal pressure zone length and the lower esophageal sphincter pressure and the ratio of elevated intragastric pressure. The results showed that there was no significant difference in the pressure of the lower esophageal sphincter at rest (12.7 ± 1.18mmHg vs 13.7 ± 0.73mmHg) before and after surgery. The length of the high-pressure zone (3.85 ± 0.15 and 3.73 ± 0.17 cm) is also basically close. No change was observed after normal swallowed relaxation.
