Upon receipt of this event spatz had investigated the case and found that the patient had active acid reflux requiring ppi for control - symptoms recurred with missed dosing.Under those circumstances the post approval study protocol states that 200 ml is the recommended balloon adjustment however, the patient was given an addition of 300 ml.Additionally, a review of the device labeling notes the following: failure of patients to take prescribed daily proton-pump inhibitor medication increases the risk of gastric ulceration or perforation.Each patient must be monitored closely during the entire term of treatment to detect the development of possible complications.Each patient should be instructed regarding signs and symptoms of balloon deflation, gastrointestinal obstruction, perforation, ulceration, and other complications, which might occur, and should be advised to contact his/her physician immediately upon the onset of such signs and symptoms.Any change in symptoms - new onset nausea, vomiting, pain, or trouble breathing - needs to be addressed by the doctor.The cause may include dietary indiscretion, ulceration, hyperinflation, perforation, or obstruction.In certain circumstances the doctor will choose to do an x-ray, or endoscopy, if dietary/medication changes do not alleviate symptoms.Prompt attention is recommended to prevent serious complications.Inflation volumes above 850 ml are not recommended and may increase risk of intolerance, balloon deflation, gastric ulceration and/or gastric perforation.Section 10.3.D - balloon volume up-adjustments are recommended for patients between weeks 14-24, who have diminished balloon effect, and who are asymptomatic, with bmi above 25, and without any evidence of gastric ulcer, erosive gastritis, esophagitis (any grade).A letter was sent to all study pis emphasizing the criteria for up adjustment and the importance of following the post approval study protocol.
