Hi, Unfortunately, this is an absolute. You are at a higher risk of complications if you've had prior stomach surgery, including Nissen fundoplication, which makes this an absolute contraindication to Orbera placement. Other stomach surgeries, such as prior LabBand, gastric bypass, or gastric sleeve, would also be contraindications. Several Orbera case reports outside of the United States indicated that stomach rupture may occur in individuals with a history of stomach surgery. Though extraordinarily rare, this is obviously a serious complication and not worth the potential risk. Stomach rupture has not been reported in individuals without a history of stomach surgery. We think that prior surgery creates scar tissue, which alters the ability of the stomach to accommodate properly to the balloon, leading to potential complications.
