Abstract: A flexible self‐expanding esophageal stent, made entirely of absorbable materials, was recently developed by the authors. The new stent consists of two components: a rolled vicryl sheet (Vicryl woven mesh, Ethicon) which has a 20‐mm outer diameter, and a PDS string (PDS II, 1 ‐0. Ethicon) which runs spirally around the rolled sheet. The stent is almost equal in flexibility to the Ultraflex (Microvasive, USA) and its expanding force exceeds that of the Ultraflex. This stent was uneventfully placed in the porcine esophagus and then fully opened. This absorbable stent, incubated in 37°C saline, showed a gradual diminution of its expanding force over a period of more than two weeks. We conclude that this novel absorbable stent, which has characteristics comparable to those of a metallic stent, as well as certain other advantages, is applicable to clinical cases.
