Figure 5 Process of thoracoscope-assisted tunnel endoscopic resection. A: Thoracoscopic exploration of the tumor; B: Endoscopic exploration of the tumor; C-D: A submucosal tunnel was created to expose the tumor under endoscopy, which was the same as the submucosal tunneling endoscopic resection procedure; E: The thoracoscopic electric hook was used to separate the esophagus and open the muscular layer over the tumor by blunt dissection, we removed the large tumor from the chest; F: Use of metallic clips to close the mucosal entry; G: Use of thoracoscopy to suture the pleura mediastinalis; H: The lesions.
