Metal stenting to resolve post-photodynamic therapy stricture in early esophageal cancer

Figure 1 Gastroscopy before photodynamic therapy. A: Gastroscopy showed a flat and reddish lesion in the mid-esophagus (a biopsy showed squamous cell carcinoma); B: Gastroscopy showed an unstained lesion after spraying Lugol solution in the mid-esophagus.

Figure 2 Two days after Photodynamic therapy. Endoscopy showed circumferential coagulation necrosis with an ulcer in the photodynamic therapy-treated lesion.

Figure 3 Two months after Photodynamic therapy. Endoscopy showed luminal narrowing with fibrous scarring changes in the photodynamic therapy-treated lesion.

Figure 4 Fluoroscopic image showed a metal stent at the stricture site in the esophagus.

Figure 5 Endoscopy showed improvement of the previous stricture site 2 mo after stent removal.
