    Abstract:
    Percutaneous endoscopic gastrostomy (PEG) is well established as a safe and effective means of providing enteral feeding access in patients unable to tolerate oral feeding. There is some question, however, as to the true incidence of free air after PEG and the clinical significance of free air in these patients. We report our experience with 119 patients over 4 years who underwent placement of a percutaneous gastrostomy tube. This study is a retrospective review of percutaneous endoscopic gastrostomies performed by the Critical Care Service for Surgery (CCSS). A database of percutaneous endoscopic gastrostomies performed by the CCSS was maintained from September 1997 through December 2001. Complications of percutaneous gastrostomies were added to the database when noted. The electronic medical record of all patients was reviewed for the results of radiographic studies. Prior abdominal operations were noted as well as gastrostomy tube complications and outcome. A total of 115 intensive care unit patients underwent PEG placement by the CCSS. This total includes 18 patients who had undergone prior upper abdominal surgery, Three additional patients who underwent placement of a gastrostomy tube by vascular interventional radiology and one patient who underwent PEG placement by the ear, nose, and throat service were brought to the attention of CCSS secondary to complications for a total of 119 patients. Only four patients (3.4%) were found to have free air on subsequent chest radiograph. Six patients (5.2%) were found to have free air on abdominal CT scans. Two patients with free air on CT underwent exploratory celiotomy as a result of additional signs of peritonitis. Both were negative explorations. The incidence of free air after PEG in our experience is significantly less than the incidence in previous studies. In patients with free air after PEG placement exploratory celiotomy is not indicated in the absence of other clinical findings of peritonitis. Additionally it was noted that PEG placement could safely be performed in patients with prior upper abdominal surgery with a low incidence of complications.
