A Case of Hepatic Portal Venous Gas as a Complication of Endoscopic Balloon Dilatation

ABSTRACT

The development of hepatic portal venous gas (HPVG) is rare but it might be associated with serious disease and poor clinical outcome. Recently, several iatrogenic causes of HPVG have been reported. HPVG as a complication of endoscopic balloon dilatation is a previously unreported event. We experienced a case of HPVG after endoscopic balloon dilatation in a 31 yr-old man with pyloric stricture due to corrosive acids ingestion. The patient was treated conservatively with fluid resuscitation, antibiotics and Levin tube with natural drainage. Five days later, the follow-up CT scan showed spontaneous resolution of HPVG. This case reminded us the clinical importance and management strategy of HPVG. We report here a case of iatrogenic HPVG with a review of relevant literature.
