Endoscopic variceal ligation combined with endoscopic submucosal dissection in the treatment of esophageal varices complicated by early esophageal cancer

Endoscopic variceal ligation combined with endoscopic submucosal dissection in the treatment of esophageal varices complicated by early esophageal cancerVideo 1 A new technique for treating esophageal varices complicated by early esophageal cancer. Fig. 1 Preoperative imaging.a Endoscopy showed a red section of mucous membrane at 30-33 cm from the incisors.b The lesions under narrow-band imaging were slightly brown.c Magnifying endoscopy showed dilation and distortion of intraepithelial papillary capillary loop.d Endoscopic ultrasonography showed that the local mucosa was hypoechoic and slightly thickened, and the submucosa, lamina propria, and adventitia were of normal appearance. Fig. 2 Postoperative pathology con- firmed high grade mucosal intraepithelial neoplasia.
