Anastomotic leakage (AL) remains a major complication after esophagectomy, especially in patients with esophagogastric cancers who have undergone neoadjuvant therapies, which can impair tissue healing. Endoscopic vacuum-assisted closure (EndoVAC) is an innovative approach aimed at managing AL by facilitating wound drainage, reducing infection, and promoting granulation tissue formation, thus supporting effective healing. This review explores the role and effectiveness of EndoVAC in treating AL post-esophagectomy in esophageal cancer patients. We present an overview of its physiological principles, including wound contraction, enhanced tissue perfusion, and optimized microenvironment, which collectively accelerate wound closure. In addition, we examine clinical outcomes from recent studies, which indicate that EndoVAC is associated with improved leak resolution rates and potentially shorter hospital stays compared to traditional methods. Overall, this review highlights EndoVAC as a promising tool for AL management and underscores the need for continued investigation to refine its protocols and broaden its accessibility. By optimizing EndoVACs use, multidisciplinary teams can improve patient outcomes and advance esophageal cancer care.
