[0002] In current medical practice, the use of a feeding tube is crucial for postoperative nutritional support of patients who have undergone esophageal cancer surgery. The traditional method of placing a feeding tube usually involves inserting it into the jejunum through the patient's nasal cavity during esophageal cancer surgery at an appropriate time to ensure that the patient can receive the necessary nutritional supplements after surgery.

[0003] However, this traditional method of placing a feeding tube faces challenges in two-incision esophageal cancer surgery. The procedure first involves abdominal cavity manipulation to prepare for anastomosis of the stomach and esophagus by creating a tubular stomach. Subsequently, the surgery enters the thoracic cavity stage, where the prepared tubular stomach is pulled into the thoracic cavity and anastomosed with the esophagus. Due to the particularity of this surgical approach, conventional feeding tubes cannot be successfully placed in the predetermined position during surgery.

[0004] To overcome this difficulty, other methods have been attempted in clinical practice. For example, performing jejunostomy during surgery, although this method can solve the problem to some extent, undoubtedly increases the trauma of surgery and brings more pain and difficulty in recovery to the patient. Another option is to use total parenteral nutrition after surgery, but this places higher demands on the patient's economic burden and long-term nutritional management. In addition, there is also a scheme of placing a feeding tube through an endoscope during or after surgery, although this method may be effective in certain cases, it also brings additional costs, trauma, and discomfort to the patient.
