Percutaneous endoscopic gastrostomy (PEG) is widely used for providing long-term feeding access. Although generally considered safe, PEG can be associated with significant complications. The finding of hepatoportal venous gas (HPVG) is often associated with potentially lethal conditions requiring immediate surgery. We report a rare PEG complication by the manifestation of HPVG related to PEG tube dislodgement. The patient underwent emergent exploratory laparotomy under the impression of bowel ischemia with sepsis. The operation revealed dislodgement of the PEG tube bumper into the peritoneal cavity between gastric wall and anterior abdominal wall. There was no evidence of ischemia, perforation, or gangrene in the intestine. We believe the source of HPVG in our
