Gastric outlet obstruction due to an intragastric balloon in a patient returning from the Caribbean

Abstract

Key Clinical MessageGastric outlet obstruction can be a dangerous complication of intragastric balloons, as it can result in severe metabolic alkalosis. As weight loss procedures and medical tourism become more popular, physicians should have a high index of suspicion for complications of invasive procedures, particularly in returning travelers.AbstractIntragastric balloons for weight loss have decreased in frequency in the United States. However, they are still frequent in low‐ and middle‐income countries. Severe complications occur in less than 3% of patients who undergo this procedure. Herein, we present a case of gastric outlet obstruction, severe metabolic alkalosis, and refeeding syndrome in a patient returning from the Dominican Republic. She presented with 2 weeks of emesis and obstipation, followed by a pre‐syncope and altered mental status. An intragastric mass was observed on computerized tomography, which was characterized as an intragastric balloon and retrieved endoscopically. All metabolic derangements were corrected, and the patient improved without sequelae. As weight loss procedures and medical tourism become more popular, physicians should have a high index of suspicion for complications of invasive procedures, particularly in returning travelers.
