case_images: (a) EGD revealed a flat lesion in the esophagus, covering approximately half of its circumference. (b) Chromoendoscopy showed non-staining with iodine. (c) Magnifying endoscopy with narrow-band imaging revealed severe irregular vessels including type B2. (d) PET-CT scan detected metastasis to the peritracheal lymph nodes. EGD, esophagogastroduodenoscopy; HBOT, hyperbaric oxygen therapy; PET-CT, positron emission tomography-computed tomography.

case_images: Magnifying endoscopy with narrow-band imaging revealed severe irregular vessels including type B2, according to the classification of the Japan Esophageal Society, with a predicted invasion depth of T1a-MM or T1b-SM1 (Figure 1a-c). Positron emission tomography-computed tomography revealed esophageal cancer with metastasis to the peritracheal lymph nodes (Figure 1d).
case_images: At 3 months post-initial discharge, EGD revealed ulcers and strictures in the midthoracic esophagus. EGD, esophagogastroduodenoscopy.

case_images: EGD revealed a circumferential active ulcer with strictures in the midthoracic esophagus (Figure 2).
case_images: (a, b) At the time of the third admission, EGD and radiography examination showed no improvement in esophageal ulcers and strictures, impeding passage of the endoscope. EGD, esophagogastroduodenoscopy.

case_images: After hospitalization, EGD revealed no improvement in the esophageal circumferential ulcer with stricture (Figure 3).
case_images: (a) After 10 HBOT sessions, EGD revealed improvement in esophageal ulcers and strictures, allowing passage of the endoscope. (b, c) EGD and radiography conducted 3 months after completing 20 HBOT sessions demonstrated sustained improvement in esophageal ulcers and strictures. EGD, esophagogastroduodenoscopy; HBOT, hyperbaric oxygen therapy.

case_images: EGD showed epithelialization of the esophageal ulcers without strictures, allowing passage of the endoscope (Figure 4a). EGD confirmed sustained improvement in esophageal ulcers and strictures. Esophageal radiography also revealed an improvement in peristaltic movement, without strictures (Figure 4b,c).
