Zusammenfassung:An esophageal fistula is a pathological connection between the esophagus and another structure. The most common treatment for an esophageal fistula is airway stenting. However, several case series have demonstrated the superiority of the over-the-scope clip (OTSC) system for fistula closure. We report a case requiring multiple stent/OTSC placements in an esophageal-pleural fistula (EPF) due to underlying malignancy. A 57-year-old male with stage IV esophageal cancer with an esophageal stent presented with three days of back pain and shortness of breath. A gastrografin was performed and showed a fistula at the proximal aspect of the pre-existing esophageal stent. A self-expandable metallic stent (SEMS) was utilized to bridge the fistula to the pre-existing esophageal stent. An esophagram two days later revealed extravasation and continuous esophageal leak. OTSC was then deployed at the fistula. A SEMS was also implanted through the patient's pre-existing stent. Endoscopy showed persistent esophageal perforation. The initial OTSC and SEMS combination was removed. After removal, a second OTSC was placed over the fistula, allowing for complete suction of the fistula into the OTSC clip cap. We followed this by deploying another SEMS through the pre-existing stent and clipping them together. The proximal end of this new stent fully covered the fistula, creating a complete seal. This case is notable in that successful EPF closure secondary to existing esophageal stent erosion was achieved by utilizing a properly positioned OTSC with stent-within-stent combination management.
