The most recent approaches to the treatment of postoperative esophageal strictures usually include probe dilation, balloon catheter dilation, and esophageal metal stenting. Patients should identify the cause of anastomotic stricture after esophagectomy and treat accordingly. 1. Probe dilatation: it is usually applied to patients with anastomotic stenosis with an internal diameter of not less than 0.2 cm, but patients need multiple dilatations to consolidate the efficacy of the treatment. 2. Balloon catheter dilatation: it can be used under direct endoscopic guidance. This method is safe and reliable, especially for anastomotic stenosis with eccentricity, angular deformity and severe stenosis. 3. Esophageal metal stent treatment: Titanium memory alloy stent is mostly used, which has the advantages of self-expansion, abrasion resistance and corrosion resistance. In addition to neck anastomosis, it can treat severe scar stenosis with good effect. In daily life, patients should have a reasonable diet, less oil and salt, avoid spicy stimulation, maintain a good mood, regular work and rest, and cooperate with the doctor for regular review.
