11 weeks later, the patient underwent a gastroscopy (Fig. 2), which found that ”a stenotic segment was visible at a distance of 16-20cm from the hilar tooth and the gastroscope (Olympus GIFXP260: 9 mm) could not be passed”. After absolute contraindications were ruled out, the patient was treated with careful serial graded dilatations by selecting an initial dilator size based on the estimated stricture diameter(diameters of 7mm, 9mm, 11mm, 13mm, 15mm), the number of bougies ≤3 at a time. From January 22, 2017, to February 19, 2017, the patient used to be handled with weekly dilatation per week, with unfavorable outcomes after 5 therapies. Esophageal stent placement or ERI was indicated when dilatation is not successful. After that, the patient was treated endoscopically if the Stooler[9] grade of his dysphagia was ≥2. From February 26, 2017 to April 19, 2018, The patient underwent 4 times stent placement (The average remission time of his dysphagia was 47.25 days) combined with intermittently dilatation 13 times (the average remission time was 18.85 days) to improve esophageal dysphagia. Due to scar constitution, stent migration, stent dislocation, and so on, the patient still had recurrent dysphagia. So from May 17 to September 27, 2018, the patient underwent endoscopic radial incision (ERI) for 4 times (the average time of remission was 59.75 days) while taking oral steroids (the initial amount was 30 mg qd, and the amount was reduced by 5 mg every 2 weeks until the drug was stopped. During the period of oral steroids, the patient was treated with ERI 3 times and once stenting, the mean remission time was 33.25 days) and once ERI, after therapies his dysphagia improved significantly. However, the patient reoccurred dysphagia grade 3 again after 5 months, he chose dilatation 6 times again from February 24, 2019, to September 15, 2019 (the average remission time was 37.83 days), and then he was stented 1 time (the remission time was 98 days). Implanted stents was difficult to take out several times due to the severe scar hyperplasia (Fig. 3), so that the patient was continued to be maintained on dilatation 6 times (the average remission time was 127.33 days). The patient had no similarly esophageal strictures and able to eat solid food at 2 years of follow-up. The therapy has achieved a favorable outcome (Figure 4).
