<unk>  occurs when this internal<unk>  erodes into the wall of the stomach, sometimes becoming entirely<unk>  within the wall of the stomach.<unk>  tends to be a late complication of gastrostomy tube placement, but can rarely occur as early as 1 to 3 weeks after tube placement. Most cases occur more than 1 year after initial placement of the PEG tube. Excessive tightening of the external<unk>  is the primary risk factor for<unk> . Maintaining the external<unk>  in a loose position may help prevent<unk> . Additional risk factors include obesity, medications, poor wound healing, malnutrition, etc. Feeding tubes with soft balloon internal<unk> s are less likely to cause<unk> , compared with more firm or stiff polyurethane internal<unk> s. Signs and symptoms==<unk>  may be asymptomatic, especially early in the course. Dysfunction of the tube occurs commonly, including leakage around the insertion site, inability to administer feedings or fluids, or need for more pressure when giving feeds.<unk>  may cause abdominal pain or swelling (erythema) at the site of insertion of the PEG tube. Less commonly,<unk>  may also be complicated by acute infectious illness (sepsis), abscess formation, gastrointestinal bleeding or peritonitis. In some cases, the internal<unk>  may be felt by palpating the abdomen. Inspection of the tube typically reveals an inability to easily rotate the tube.
