Core Tip

Core tip: There are few reports about how to manage enterocutaneous fistulas (ECFs) after open abdomen, especially those that are unlikely to achieve spontaneous closure. This case report describes how to use 3D printing technique to fabricate a fistula stent in accordance with the ECF anatomy, and how the stent can improve enteric effluent, patient’s nutrition and physical strength, and surrounding wound inflammation.
