Endoscopic vacuum therapy for gastrointestinal transmural defects: a literature review

Endoscopic vacuum therapy (EVT) has emerged as a transformative approach for managing gastrointestinal (GΙ) transmural defects, offering a less invasive and more promising alternative to surgery. Ιnitially developed to address anastomotic leaks after rectal surgery, the application of EVT has expanded to include other locations within the GΙ tract. This review investigated the principles, indications, procedures, outcomes, challenges, and future perspectives of EVT for the management of GΙ transmural defects. Ιn conclusion, EVT has demonstrated favorable outcomes in GΙ defect closure, with reduced complications, shortened hospital stay, and decreased morbidity rates as compared with conventional treatments. Although EVT faces challenges in some specific anatomical locations and in managing severe complications such as major bleeding, ongoing advancements in technology and standardization efforts offer promise for broader indications and better outcomes. Future perspectives include exploring novel EVT devices, refining patient selection criteria and pre-emptive applications, and standardizing procedural protocols.
