We highlight a cost-effective modified endoscopic vacuum therapy (EVT) technique for the management of gastrointestinal transmural defects and demonstrate the step-by-step process of manufacturing this device in detail. The modified sponge is constructed using a nasogastric tube, gauze, and antimicrobial incise drape. In this video, we also describe this approach’s advantages in the management of 3 patients with upper and lower gastrointestinal transmural defects.

The potential benefits of this cost-effective approach include easy placement, longer intervals between EVT systems exchanges, low cost, and lower rates of adverse events.

The modified EVT is easily inserted and increases the interval between the EVT system exchanges. This cost-effective technique may expand EVT use by providing less-invasive treatment to more patients around the world, especially in developing countries.
