Objectives
Narrative objectives1
Esophagectomy for esophageal cancer has a variety of surgical strategies in reconstructions using gastric conduits, which may affect the patients' postoperative daily-life activities. The aim of this study is to evaluate the differences of the physiological environment inside gastric conduits in each reconstruction strategy in terms of peristaltic intensity and digestive juice reflux, using a High Resolution Manometry (HRM) device and a 24-hour pH monitoring device.

Assessment
Primary outcomes
1) Differences in peristaltic intensity among gastric conduit reconstruction strategies in the fasting state.
2) Differences in DeMeester scores/Time percentage below pH4 at the (remnant) esophagus levels among gastric conduit reconstruction strategies.
Key secondary outcomes
1) Changes in peristaltic intensity and frequency of peristalsis of the gastric conduit in each patient.
2) Correlation between the refluxive inflammation levels and the peristaltic intensity levels (include gross evaluations with endoscopic examinations).
3) Correlation between the refluxive inflammation levels and the DeMeester scores/Time percentage below pH4 at the (remnant) esophagus levels.
4) Correlation between the peristaltic intensity levels (include gross evaluations with endoscopic examinations) and the DeMeester scores/Time percentage below pH4 at the (remnant) esophagus levels.
5) Correlation between the nutritional markers (Onodera's prognostic nutritional index, serum PreAlb level, change in body weight)and the peristaltic intensity levels (include gross evaluations with endoscopic examinations).
6) Correlation between the nutritional markers (Onodera's prognostic nutritional index, serum PreAlb level, change in body weight)and the DeMeester scores/Time percentage below pH4 at the (remnant) esophagus levels.
7) Comparision between the postoperative patients and the preoperative patients in terms of periastaltic intensity levels and DeMeester scores/Time percentage below pH4 at the (remnant) esophagus levels.
8) Correlation between the lapsed months after the surgeries and the periastaltic intensity levels.
9) Correlation between the lapsed months after the surgery and the DeMeester scores/Time percentage below pH4 at the (remnant) esophagus levels.
10) Correlation between the QOL questionnaire results and the refluxive inflammation levels.
11) Completion rates of the examinations.

Interventions/Control_1
1)Blood sampling at the outpatient ward before the examinations below (~5 munites).
2) Endoscopic examination of the gastric conduit under video fluoroscopy and the placement of a marking clip on the oral side near the Pylorus (~10 minutes).
3)Intranasal placement of the High Resolution Manometry (HRM) catheter through the gastric conduit and the recording of the manometric data during a fasting state (90 minutes).
4) Recording of the manometric data of the gastric conduit whlie swallowing diluted contrast under video fluoroscopy (~10 minutes).
5) Recording of the manometric data of the gastric conduit during the fed state after liquid meal intake (90 munites).
6) Removing the HRM catheter and intranasal placement of the 24-hour pH monitoring catheter for 24-hour pH recording (24 hours).
7) Removing the 24-hour pH catheter (5 minutes).
