title: Hepatic Portal Venous Gas: An Unusual Complication Following Upper Endoscopy and Dilation.
abstract: Hepatic portal venous gas (HPVG), a rare condition in which gas accumulates in the portal venous circulation, is often associated with a significant underlying pathology, such as intestinal ischemia, sepsis, and trauma. HPVG after endoscopy or dilation is an unusual complication. We report a case of HPVG following upper endoscopy and dilation for an esophageal stricture in a 34-year-old patient with eosinophilic esophagitis (EoE). The patient was treated conservatively, and his symptoms resolved. Follow-up computed tomography (CT) scan showed resolution of HPVG. This case highlights a rare and potentially ominous complication of upper endoscopy and dilation and underscores the role of conservative management.
