Each physician should use caution when considering CSA treatment for high risk patient situations, specifically regarding the ability to extract gas from the esophagus and stomach. Consult the Instructions for Use for additional information.
IMPORTANT SAFETY INFORMATION
The CSA System is contraindicated for use during pregnancy, where significant esophageal ulceration or mucosal break is evident, where esophageal narrowing exists that precludes advancing into the stomach, where any procedure or anatomy has significantly reduced or restricted the volume of the stomach including but not limited to gastric bypass, stomach stapling, and gastrojejunostomy, where any disease state has significantly reduced the elasticity in the GI tract (e.g. Marfan's syndrome), and where food is identified in the stomach or proximal duodenum at the time of the procedure and cannot be removed. The most common side effects include chest pain, sore throat, difficult or painful swallowing. Other rare but serious side effects may occur. Always consult with a physician to determine whether this treatment may be appropriate for you.
