Curative endoscopic closure of a chronic esophagopleural fistula after Boerhaave syndrome using an over-the-scope clip: A case report

Figure 3 Endoscopic and contrast findings at the time of transfer to our hospital (1 year after onset). A: Upper gastrointestinal endoscopy revealed a well-demarcated fistulous opening approximately 2 mm in diameter on the left wall just above the esophagogastric junction; the surrounding mucosa showed only mild erythema, without marked edema or necrotic changes; the esophagopleural fistula is indicated by an arrow; B: Contrast injection through a catheter inserted into the fistula demonstrated immediate flow of the contrast medium into the left pleural abscess cavity, confirming persistent communication of the esophagopleural fistula.
