摘要
目的探讨贲门癌术后胸腔内残余食管胃的功能变化情况。方法选取研究对象56例,其中对照组15例为健康志愿者,行食管腔内压力测定和24hpH监测;术后组41例为贲门癌切除术后患者,行上消化道X线钡餐造影、食管腔内压力测定和24hpH监测,分析其临床意义。结果测压显示41例患者术后吻合口压力明显低于对照组食管下括约肌和残余食管压力(P<0.05),术后组残余食管静息压均明显高于对照组食管静息压和胸腔内胃的静息压(P<0.05),食管体部蠕动收缩压术后组低于对照组;24h食管pH监测结果表明,两组间pH<4的立位、卧位和总时间及反流次数与时间均存在显著差异(P<0.01),卧位与立位pH<4的总时间有显著差异(P<0.01);术后组上消化道X线钡餐造影显示胸腔内胃体部无蠕动性收缩且胃排空延迟。结论贲门癌术后存在食管反流,反流的发生与术后胃排空延迟有一定关系。
Objective To study the function of intrathoracic stomach and esophagus after cardiac cancer operation. Methods Fifteen healthy volunteers were as normal control group, and 41 post-operative patients with cardiac cancer as another group. Intro-esophageal pressure and 24 h pH were monitored. In addition, X-ray barium meal was carried out to all 41 patients. Results The pressuer at esophago-gastric anatomotic portion in cancer patients was lower than that at LES of normal esophagus, and intrathoracic stomach. The pressure of residual esophagus was higher than that of normal esophagus and intrathoracic stomach. The peristaltic contraction pressure of post-operative esophagus was lower than that of normal esophagus. The signifcant pH diference could be observered between post-operative esophagus and normal e- sophagus. The X-ray barium meal showed that there was no peristaltic contraction in the intrathoracic stomach and the intrathoracic stomach had delayed emptying. Conclusion Gastroesophageal reflux existed in the post-operative patients of cardiac cancer, which is related to the delayed emptying of intrathoracic stomach.
