NO
Substance P (SP) is a transmitter to be produced by stimulation of dopamine produced in the basal ganglion, to be secreted from the nerve termination of the glosspharyngeal nerve and vagus nerve to the pharynx and to regulate the swallowing reflex. It has been reported that patients with stroke have a high risk of aspiration pneumonia, which has a close relationship to the decrease of SP concentration in the plasma or the sputum. However, there is no evidence of the association with low plasma SP concentration and subclinical infarction adjacent to the basal ganglion. On the other hand, postoperative aspiration pneumonia is one of severe complications with fatal possibility after esophagectomy for esophageal cancer. The improvement of surgical procedure and perioperative management cannot still prevent development of postoperative aspiration pneumonia completely. We speculate such patients who develop aspiration pneumonia despite various kind of measures might have low plasma SP concentration preoperatively and also have subclinical cerebral infarction. Then, to elucidate the validity of our speculations, we first investigate the association with preoperative low plasma SP concentration and subclinical cerebral infarction adjacent to the basal ganglion.
Others
Next, we plan to examine whether preoperative low plasma SP concentration has a close association with postoperative swallowing dysfunction or not and whether it is sensitive for detection of patients with high risk of postoperative aspiration preoperatively or not.

The enrolled patients provide blood sample for measuring the concentration of plasma substance P (SP) and undergo the examination of brain MRI and the evaluation of swallowing function by videofluorography (VF) by doctor belonging to the rehabilitation unit and by videoendoscopy (VE) by otolaryngologist preoperatively. Then, before starting a meal after operation, the evaluation of postoperative swallowing function by VF and VE are conducted. If patient developed aspiration or aspiration pneumonia, the collection of blood sample for measuring plasma SP concentration and the swallowing evaluation by VE if possible is planed to be carried out.
