Abstract

A 38-year-old female with medical history of breast cancer, hypertension, diabetes mellitus and obesity (body max index 55kg/m2), was admitted to the emergency room with complains of nausea and vomits. Three weeks prior to the presentation, she placed an intragastric balloon (IGB) (Orbera365™, Apollo endosurgery Inc., Austin, TX), for weight loss, filled with 600ml solution of saline and methylene blue dye. Upon physical examination, she was dehydrated and presented with a bulging of the upper abdominal wall associated with mild abdominal pain. Laboratory tests showed severe metabolic alkalosis, hypocalcemia and hypokalemia. Abdominal x-ray revealed gastric distension with an increased size IGB, measuring 164.3*145.6*144.1 mm (estimated volume of 1800mL), with an air-fluid level. Upper endoscopy revealed the balloon stuck in the antrum. A catheter needle was used to puncture and deflate the balloon. Once deflated it was removed with endoscopic forceps. The fluid was not sent for microbiologic culture. After IGB removal, hydroelectrolytic disturbances were resolved and oral feeding was promptly resumed without further complications.
