Efficacy of the cardiac septal occluder in the treatment of post-bariatric surgery leaks and fistulas.

Background: Endoscopy has evolved to become first-line therapy for the treatment of post-bariatric leaks; however, many sessions are often required with variable success rates. Due to these limitations, the use of the cardiac septal defect occluder (CSDO) has recently been reported in this population.

Methods: The study population was a multicenter retrospective series of patients with post-bariatric surgical leaks who underwent treatment with CSDO placement.
