In many cases, the manometric examination is not feasible because of the pharyngeal sinusitis or pharyngeal torsion. In addition, although previous conventional manometry was used to estimate pharyngeal swallowing, the bolus flow transmission was still not evaluated, which still depended on the videofluoscopic swallowing studies. High resolution impedance manometry could help us to measure the bolus flow according to the impedance changes. However, the comparison between two approach methods of postoperative recovery of swallowing function is still inconclusive. In this study, we aimed to examine the correlation between high-resolution manometric and videofluoroscopic (Barium) measurements of the swallowing function.

For the patients and method decription, consecutive patients who will fulfill the criteria of elective esophagectomy patients aged >= 20 will be enrolled. After got the inform consent, these patients receive the swallowing function by barium examination and HRIM.
