Esophageal anastomotic leaks remain a life-threatening postoperative complication of upper gastrointestinal surgery. In Germany, self-expandable metal stents (SEMS) and endoscopic vacuum therapy (EVT) are established endoscopic treatment options [1]
[2], but no evidence points to the superiority of either of these [3]. Consequently, new approaches aim to combine both procedures [4]
[5].
One available medical device that combines EVT (sealing and drainage) with SEMS treatment (sealing and food passage) is a fully covered SEMS coated with a polyurethane foam (VACStent; Möller Medical GmbH, Fulda, Germany) ([Fig. 1]). To our knowledge, this is the first report on using a hybrid SEMS for treating an esophageal anastomotic leak ([Video 1]).

Qualität:
A 61-year-old man with an esophageal anastomotic leak ([Fig. 2]) had undergone previous total gastrectomy for a signet cell carcinoma of the stomach. On the 16th postoperative day (POD), the patient was admitted to our hospital in a septic condition, having been treated unsuccessfully with an over-the-scope clip (Ovesco Endoscopy AG, Tübingen, Germany). We performed an endoscopy (POD 16) and discovered a semicircular anastomotic leak of the esophagojejunostomy with an abscess cavity. We removed the clip and applied a VACStent (125 mmHg negative pressure) to treat the leak. A computed tomography scan with oral contrast ([Fig. 3]) confirmed sealing of the leak so that oral intake of fluids was possible.

Fig. 3 Axial computed tomography with oral contrast showed complete sealing of the leak by the VACStent (yellow arrow) with a thoracic drain (asterisk).
The following endoscopy (POD 18) demonstrated a healing tendency; consequently, we placed a second VACStent. After VACStent removal (POD 22), we observed a sealed leak with a small and encapsulated wound cavity ([Fig. 4]). A digestive swallowing test confirmed the sealing. Although the postoperative course was delayed because of pulmonary complications, the patient was discharged (POD 39) ([Fig. 5]) with full oral intake and no clinical signs of a residual anastomotic leak.
