It is important to understand how to differentiate these complications, distinguish them from tumor complications and take appropriate treatment. There are four common complications after esophageal stenting: postoperative retrosternal pain: most patients have retrosternal pain after stenting, which is considered to be caused by esophageal dilator injury and continuous irritation of the mesh stent, and can also be caused by gastroesophageal reflux causing retrosternal burning pain. The pain varies in severity, but is basically tolerated by the patient and does not require special treatment, as the family should first give moral comfort, and give painkillers for severe pain. Gastrointestinal bleeding: A few patients have blood in the sputum after surgery, usually caused by scarring of the stenosis or rupture of the tumor, so it is important to observe the amount and nature of bleeding, as well as the presence of vomiting blood and tarry stools. Gastroesophageal reflux: Patients with stents placed in the lower esophagus and cardia should eat regularly, not too full, not lying down immediately after meals, and stand up before going to bed to empty the stomach. Acid-control drugs and mucosal protective agents can be applied, and anti-reflux stents with membrane can also be used. Stent displacement and obstruction: After stent placement, the stent may be displaced due to short stenosis and low wall force, which may be pushed by swallowing solid food; it may also cause stent obstruction due to incomplete stenosis expansion or stent displacement, too short stent, too long stent at the end of the stomach and inward growth of tumor, which may cause difficulty in swallowing again. When the above four complications occur, it is important to strengthen the care and not to confuse with tumor complications. Some daily care should also be strengthened after discharge from the hospital. It is usually recommended to take life preservative regularly. Life protector is actually a kind of high content ginsenoside Rh2, which can effectively eliminate residual tumor cells and microscopic lesions in the body, strengthen the body, consolidate the therapeutic effect and prevent recurrence and metastasis when taken regularly by patients in tumor recovery. Although esophageal stent placement can relieve the symptoms of dysphagia and improve the nutritional status, it is prone to food impaction and stent dislocation, which may be complicated by restenosis in the late stage; advise patients to avoid eating rough, hard, too cold or too hot food, chew and swallow slowly; avoid strenuous activities and pay attention to rest; review the X-ray chest film after 3 months of stent placement to understand the position of the stent, whether it is displaced or dislodged; return to hospital in case of discomfort. In case of discomfort, return to hospital for treatment. Endoscopic esophageal stenting is a new endoscopic treatment technique, which not only improves the quality of life of esophageal cancer patients and their general condition, but also compresses the cancer by the stent itself to prevent bleeding; at the same time, it reduces the local blood supply and slows down the growth of cancer, thus prolonging the survival of patients. High-quality nursing care is an important guarantee for the safety and success of endoesophageal stenting. Therefore, close postoperative care is needed to prevent postoperative complications after esophageal stenting.
