Currently, both the subtotal stomach and narrow gastric tube approaches are widely used for esophagogastric anastomosis after esophagectomy. Some stud- ies have concluded that the subtotal gastric conduit is superior to the wide gastric-tube approach, as it provides better protection of the submucosal vessels and can slightly increase gastric capacity.
Furthermore, blood perfusion significantly decreases after tubular gastric surgery.
Stomach is the most common esophageal subtitute after a esophagectomy procedure, because it has a abundant blood supply and the need for only one anastomosis. However, cervical esophago-gastro anastomosis still has a high risk of complications, especially anastomosis leakage (11.9 - 25 % ).
There are three types of gastric subtitute: whole stomach, subtotal stomach and narrow gastric tube. While whole stomach and subtotal stomach has an advantage in the submucosal vascular network, a narrow tube is excellent elasticity and the ease with which it can be pulled up into the neck without tension, that could affect leakage rate.
On the other hand, after esophagectomy, nutrition status and quality of life (QoL) had decreased due to effect of adjuvant therapy, lower quantity of food intake, gastro-esophageal reflux and other postoperative syndromes. Several studies had shown the affect of the width of gastric tube to the postoperative nutrition and QoL, however, the results were not homogenous. This study aims to compared two types of gastric subtitute after esophagectomy: subtotal stomach and narrow gastric tube

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Subtotal stomach | Experimental | The vessels at the anastomosis of right and left gastric arteries were separated, then the proximal haft of lesser curvature and cardia was resected using linear staplers. |

| Narrow gastric tube | Active Comparator | At the lesser curvature, the resection began at the point that was 5-cm from the pyloric, toward to the greater curvature, then the stomach was divided along 3 cm from the greater curvature using linear stapler. |
