A gastrointestinal(GI) transmural defect is defined as total rupture of the GI wall,and these defects can be divided into three categories: perforations,leaks,and fistulas. Surgical management of these defects is usually challenging and may be associated with high morbidity and mortality rates. Recently,several novel endoscopic techniques have been developed,and endoscopy has become a firstline approach for therapy of these conditions. The use of endoscopic vacuum therapy(EVT) is increasing with favorable results. This technique involves endoscopic placement of a sponge connected to a nasogastric tube into the defect cavity or lumen. This promotes healing via five mechanisms,including macrodeformation,microdeformation,changes in perfusion,exudate control,and bacterial clearance,which is similar to the mechanisms in which skin wounds are treated with commonly employed wound vacuums. EVT can be used in the upper GI tract,small bowel,biliopancreatic regions,and lower GI tract,with variable success rates and a satisfactory safety profile. In this article,we review and discuss the mechanism of action,materials,techniques,efficacy,and safety of EVT in the management of patients with GI transmural defects. 展开更多
