*3.1.5 Orogastric tube insertion*

Although the preferred orogastric tube size varies between 32 Fr and 42 Fr, the average bougie size used by experts today is 36–37 French [6].

Before the first staple firing, a 36 French orogastric tube is placed by the anesthesia team. The surgeon can guide the bougie using graspers for proper placement. The tube is positioned in the antrum along the lesser curvature and not passed through the pylorus.

**Tip**: The stomach should be placed in its anatomical position, and the orogastric tube should stay parallel to lesser curvature. Also, stretching the stomach by excessive pushing of the tube compromises the straightness of the stapler line (**Figure 8**).
