Gastric Emphysema and Hepatic Portal Vein Gas as Complications of Noninvasive Positive Pressure Ventilation.

Gastric emphysema (GE) in association with hepatic portal vein gas (HPVG) is a rare, benign medical condition that is very seldom caused by noninvasive positive pressure ventilation (NIPPV). This report describes a patient who developed GE along with gastric vein gas and HPVG, most likely due to multiple episodes of vomiting in combination of using bilevel positive airway pressure (BiPAP), a form of NIPPV. The patient responded to conservative treatment with intravenous fluids, pantoprazole, and the urgent cessation of BiPAP and oral intake.
