食管癌术前B超测定胆囊收缩功能200例,Ⅰ、Ⅱ期病例的胆囊收缩功能良好率为90.9％(10/11),Ⅲ、Ⅳ期病例则仅为6.3％(9/142)和 0(0/47)。作者认为:绝大部分Ⅲ、Ⅳ期病例术前胆囊收缩功能障碍,可能与迷走神经受癌肿和/或转移的淋巴结压迫、浸润有关。术前测定胆囊收缩功能,可为术前估计临床病理分期和制定治疗方案提供有效的参数。
200 cases of gallbladder systolic function were measured by preoperative B-ultrasonography of esophageal cancer. The gallbladder systolic function rate was 90.9% (10/11) in stage I and II cases, and only 6.3% (9/142) and 0 in stage III and IV cases. (0/47). The authors believe that preoperative gallbladder systolic dysfunction in most stage III and IV cases may be related to compression and infiltration of the vagus nerve by lymph nodes in cancer and/or metastases. Preoperative determination of gallbladder systolic function can provide effective parameters for estimating clinicopathological stage and formulating treatment plan before surgery.
