Abstract
A 69-year-old Japanese man underwent successful percutaneous endoscopic gastrostomy (PEG) without any intra-procedural adverse event. However, 3 days postoperatively, he presented with melena and bloody discharge from the gastrostomy tube. Computed tomography revealed gastric emphysema, hepatic portal venous gas, portal vein thrombosis, and swelling of the ascending colon. We administered antibiotics and discontinued enteral feeding; this resulted in resolution of gastric emphysema, hepatic portal venous gas, and portal vein thrombosis and an improvement in the swelling of the ascending colon. To the best of our knowledge, till date, only three patients have been reported to develop gastric emphysema and hepatic portal venous gas after PEG. All previously reported patients were treated with antibiotics and/or discontinuation of enteral feeding, exhibiting recovery within 6-14 days. Although the occurrence of gastric emphysema and hepatic portal venous gas after a PEG procedure is rare, conservative management can ensure recovery in such patients.
