EsoGuard is a convenient five-minute procedure performed in an office setting. This procedure will collect cells from the patient’s esophagus. The patient will swallow a capsule, which is attached to a thin catheter, until the capsule reaches the stomach. The balloon is then inflated and gently pulled back until resistance is felt indicating the balloon is located at the GEJ, where target cell collection begins. Once cell collection has been completed, the collected cells will be pulled into the capsule where they are protected from dilution and contamination during the device retrieval. The balloon covered in sampled cells will then be placed in a preservation solution for transform to a diagnostic testing facility.
EsoGuard is a simple procedure that can be done in office. EsoGuard utilizes next generation sequencing, which detects precancerous cells in the esophagus. This procedure typically takes five minutes or less and does not require sedation.
As with any treatment or procedure, side effects may occur. Potential adverse events could include discomfort, throat soreness or irritation or gagging while swallowing the capsule.
You will be given specific instructions to prepare for your procedure. Your physician may request that you don’t eat or drink 2 hours before your procedure. After the procedure, patients will receive their results within 2 to 3 weeks.
