Today, another patient with esophageal smooth muscle tumor was discharged from the hospital. The patient was found to have a mass in the middle part of the esophagus after physical examination, and the esophageal ultrasound suggested that it was an esophageal smooth muscle tumor. On the second day of hospitalization, we removed the tumor, which was about 7×3×2cm in size, with the operation and postoperative recovery going smoothly, and he started to resume diet on the third day after the operation, and was discharged from the hospital on the fifth day. Traditional surgery to remove benign esophageal tumors requires an incision of 20cm, but with the assistance of thoracoscopy, only three 1.5cm holes can be made in the chest to complete the surgical operation (see the following figure), with less postoperative pain, faster recovery, and to meet the requirements of aesthetics, and a shorter hospital stay (5 days after the operation can be discharged from the hospital). Note: If ultrasound endoscopy reveals an esophageal smooth muscle tumor, do not biopsy it to avoid damage to the mucosa. Cooperate with gastroscopy during the operation to find out whether there is any damage to the esophageal mucosa.
