While endoscopic gastric balloon treatment has been successfully applied for many years, swallowable gastric balloon or elipse gastric balloon procedures have gained prominence as alternative methods due to the lack of sedation during the procedure and the absence of endoscopic assistance. In the swallowable gastric balloon procedure, the patient swallows a capsule-shaped balloon attached to a thin wire in an uninflated state with plenty of water. For patients who have difficulty swallowing the balloon, the doctor can assist the patient in swallowing the balloon using a thin guide wire. Once the balloon reaches the stomach, the doctor verifies its correct placement through imaging methods such as X-rays. An apparatus resembling a thin wire at the end of the balloon allows for inflation of the balloon. The doctor ensures that the balloon is correctly positioned and proceeds to inflate the balloon using approximately 500 mL of water containing potassium sorbate. After inflating the balloon to the desired extent, the final position is rechecked. Following thorough checks, the apparatus at the end of the balloon is carefully removed by the expert doctor. The swallowable gastric balloon procedure takes approximately 20 minutes. Since no anesthesia is administered during the procedure, the patient can return to their daily life shortly afterward. The swallowable gastric balloon has a leak-proof and soluble valve. Approximately 4 months later, the valve dissolves, the fluid inside the balloon is emptied, and the deflated balloon passes through the intestines and is excreted from the body. Due to the absence of anesthesia and endoscopy during placement and removal, the swallowable gastric balloon is one of the preferred methods for patients who have been unsuccessful in losing weight through diet and exercise.
