We plan to recruit 32 patients with esophageal cancer who have undergone minimally invasive esophagectomy (MIE) and place an enteral feeding tube. Enteral feeding is to be initiated on the second postoperative day, and the patient is to remain on enteral feeding at 300 kcal/day after discharge. The primary endpoint is adherence to enteral nutrition with HINEX® E-gel LC for up to 2 months postoperatively.

Furthermore, mice with systemic overexpression of Piezo1 showed no apparent abnormalities in growth or general activity.
