Βuried bumper syndrome presenting with hematemesis two weeks after percutaneous endoscopic gastrostomy placement.

A 63-year-old woman with recent cerebrovascular accident, presented with hematemesis 15 days after placement of a percutaneous endoscopic gastrostomy (PEG) for dysphagia. She was afebrile, had no abdominal pain, and white blood cell count was normal. Urgent upper endoscopy showed that the PEG bumper was embedded within the gastric mucosa and eroded into the abdominal wall. There was significant ulceration, erythema, and exudate. The endoscopic findings are seen in Fig. 1 and 2. The PEG was cut and endoscopically removed through the mouth with a snare. The patient was made nil per os for 48 h and kept on a proton pump inhibitor infusion. Subsequently, a nasogastric tube was placed for feedings with plan for new PEG placement at a different site.

Buried bumper syndrome occurs in approximately 0.3-2.4% of the patients [1]. Lee and colleagues reported an incidence of 8.8% occurring on average 18 months after PEG placement [2]. It is a complication of PEG placement due to inordinate pressure and traction of the internal PEG bumper on the gastric wall and, albeit rare, is associated with significant morbidity. Patients with buried bumper may manifest with difficulty to infuse feedings through the PEG, abdominal wall abscess, peritonitis or necrotizing fasciitis among others [3].
