Endoscopic vacuum therapy (EVT) for early infradiaphragmal leakage after bariatric surgery-outcomes of six consecutive cases in a single institution.

EVT is an effective and safe treatment for staple line defects or anastomotic leakage after bariatric surgeries and can therefore be adopted for the treatment of midgut wall defects. Further studies with a greater number of patients comparing surgical drainage alone or in combination with EVT versus EVT alone are needed.
