Triple-sized intragastric balloon due to spontaneous hyperinflation

Area of Science:

• Gastroenterology
• Bariatric Surgery
• Medical Devices

Background:

• Intragastric balloons (IGBs) are used for weight loss in obese patients.
• Complications associated with IGBs can include over-inflation and gastric obstruction.
• This case highlights a rare complication of IGB use.

Observation:

• A 38-year-old obese female presented with nausea, vomiting, and abdominal pain three weeks after IGB placement.
• Physical examination revealed dehydration and abdominal distension.
• Laboratory tests showed severe metabolic alkalosis, hypocalcemia, and hypokalemia.

Findings:

• Abdominal X-ray showed a significantly enlarged intragastric balloon (estimated volume 1800mL) causing gastric distension.
• Upper endoscopy confirmed the balloon was stuck in the gastric antrum.
• The balloon was successfully deflated and removed endoscopically.

Implications:

• Prompt endoscopic intervention is crucial for managing IGB complications like gastric obstruction.
• Successful removal of the over-inflated balloon resolved the patient's hydroelectrolytic disturbances.
• This case underscores the importance of careful patient monitoring after IGB placement.
