Core Tip

Core tip: Few methods can be utilized to control enteroatomospheric fistulas (EAFs) which are unlikely to achieve spontaneous closure. The 3D-printed “fistula stent” presented here can be implanted to close EAF in the early stage of open abdomen. We think that this report could start the train of thought for plugging EAF to reduce the lost enteric effluent as well as avoid water electrolyte imbalance, corrosion on the wound surface, and intra-abdominal infection.
