Esophagopleural fistula (EPF) is a rare condition that is usually accompanied by severe infection and life-threatening morbidity. Here, we report the successful treatment of an EPF by closing an esophageal orifice using the over-the-scope-clip (OTSC) system without postprocedural complications. A 41-year-old man had serious thoracic and abdominal trauma due to a traffic accident. Computed tomography revealed findings suggestive of esophageal rupture due to Boerhaave syndrome. An emergent explorative operation was performed for primary repair with the insertion of a vacuum-assisted closure device. A postoperative upper gastrointestinal series revealed an EPF tract connecting the left pleural space and distal esophagus. We performed an endoscopic procedure using the "traumatic-type"OTSC to seal the EPF, and the esophageal orifice was completely healed 2 weeks postoperatively. The OTSC system might represent a safe and feasible modality for the treatment of EPF.

The incidence of early gastric cancer (EGC) has increased to >50% in Korea owing to a higher detection rate caused by rapid advances in diagnostic instrumentation. EGC with distant metastasis has been rarely reported. Here, we report the case of a 76-year-old woman in whom general EGC was initially diagnosed by endoscopy and endoscopic ultrasonography. She subsequently underwent endoscopic submucosal dissection (ESD). Histological examination of the ESD specimen revealed that neoplastic cells were located predominantly in the submucosal layer and submucosal lymphatic channels. Metastatic cancer cells were also found in the pleural effusion. After conducting all analyses, including immunohistochemical staining, we concluded that the patient had primary EGC with pleural metastasis.

The most common cause of esophagorespiratory fistulas (ERFs) is associated with malignancy. The use of self-expandable metal stents is effective for the treatment of malignant ERFs, but benign ERF is rare, which is why its optimal treatment is not defined yet. There have been few reports describing benign esophagopleural fistula and its treatments in South Korea. Here, we report a rare case of spontaneous esophagopleural fistula, which was successfully treated by endoscopic placement of a membrane covered metal stent.
