On physical examination, the patient had bulging of the upper abdominal wall and presented diffuse pain on palpation, but she showed no other signs of peritoneal irritation or hemodynamic instability (Figure 1).

Abdominal radiography showed an increase in the diameter of the IGB (Figure 2).

After upper digestive endoscopy of the gastric cavity and aspiration of a large quantity of gastric residues, IGB hyperinsufflation was confirmed with evident high levels of gas (approximately 50% of the total volume of the balloon was filled, whereas the normal fill volume is restricted to a very small quantity) (Figure 3).

However, the IGB ruptured after puncturing it with the needle (Figure 4).

The liquid contents of the IGB were aspirated, and the balloon was removed without further complications (Figure 5).
