Image of the Space Adjuster (TOP, Tokyo, Japan). A, Space Adjuter is tranparent straight hood. B, Space Aduster is soft enough to adjust to narrow spaces.

Figure 2
Esophageal stricture because of radiation therapy for hypopharyngeal cancer located at the oral side of the lesion (yellow arrows surround the esophageal stricture). A normal hood could not pass through the esophageal stricture.
Figure 3
Figure 3
Image of esophageal squamous cell carcinoma with lugol staining (yellow arrows surround the esophageal squamous cell carcinoma). The lesion was 30 mm IIc.
Figure 4

Image of the endoscopic submucosal dissection with the Space Adjuster (TOP, Tokyo, Japan). The clip and line method was successfully enforced.
Figure 5
Figure 5
A total of 100 mg of triamcinolone acetonide was injected in the remaining submucosa after endoscopic submucosal dissection to avoid stricture.
Figure 6

Resected specimen with lugol staining. Pathological findings showed squamous cell carcinoma, pT1a-epithelium, ly(-), v(-), pHM0, pVM0.
Figure 7
Figure 7
Three months after endoscopic submucosal dissection. There was no stricture of endoscopic resection or recurrence with lugol staining (yellow arrows indicate the scar).
