trectomy and an esophagojejunal anastomosis developed a severe stricture of the surgical anastomosis (l" Fig. 1). The stricture was radiologically dilated, resulting in perforation during the dilation maneuvers. The perforation was resolved nonsurgically. The stricture recurred, so we placed a covered metal stent that was removed after 2 months, but the stricture recurred again afterwards. In this situation, we decided to place the SX-Ella-BD (Ella-CS, s. r. o., Hradec KrμlovØ, Czech Republic) – a new polydioxanone (PDS) biodegradable stent – under radiologic and endoscopic guidance (l" Fig. 2). Three months later the patient attended complaining of progressive dysphagia. Endoscopy revealed that the stent had already degraded, and a new severe stricture caused by hyperplastic inflammatory tissue was found at the level corresponding to the position of the proximal end of the stent (l" Fig. 3 and 4). The first (postsurgical) stricture now had a slightly larger diameter than before the stent placement. The hyperplasia was Severe epithelial hyperplasia as a complication of a novel biodegradable stent
