Gastrocolocutaneous Fistula: A Case Report on a Rare Complication of Gastrostomy Placement

Percutaneous endoscopic gastrostomy (PEG) tube placement is a common procedure used to provide medium- and long-term enteral nutrition to patients. Although generally considered safe, PEG tube placement can be associated with various potential complications. We report a case of gastrocolocutaneous fistula formation in a patient who presented with severe abdominal pain, new-onset diarrhea, and feculent emesis nine days after PEG tube placement. Awareness of this rare complication can facilitate the recognition of colonic perforation during gastrostomy tube placement and enable early detection of the complication post-procedurally. Additionally, we discuss various techniques that may be employed to prevent this complication during PEG tube placement.
