Pneumoperitoneum following percutaneous endoscopic gastrostomy. A prospective study
Gastrointestinal Endoscopy
|December 1, 1986
Summary
Pneumoperitoneum, or free air in the abdomen, is a common finding after percutaneous endoscopic gastrostomy (PEG) procedures. This study found it to be a benign condition requiring no intervention when patients show no signs of inflammation.
Area of Science:
- Gastroenterology
- Minimally Invasive Surgery
- Radiology
Background:
- Percutaneous endoscopic gastrostomy (PEG) is a standard procedure for enteral feeding.
- PEG reduces surgical morbidity compared to traditional gastrostomy placement.
- An unusual case of benign pneumoperitoneum post-PEG prompted further investigation.
Purpose of the Study:
- To determine the incidence of pneumoperitoneum following PEG.
- To assess the clinical significance of pneumoperitoneum after PEG.
Main Methods:
- Prospective study of 24 patients undergoing PEG.
- Radiological assessment for pneumoperitoneum post-procedure.
- Clinical evaluation for signs of peritoneal inflammation.
Main Results:
- Radiologic pneumoperitoneum was detected in 38% of patients (9/24).
- Gross pneumoperitoneum occurred in 21% (5/24); subtle free air was seen in others.
- No patient exhibited signs or symptoms of peritoneal inflammation.
Conclusions:
- Pneumoperitoneum is a frequent occurrence after PEG.
- In the absence of inflammatory signs, post-PEG pneumoperitoneum is benign.
- No further diagnostic or therapeutic intervention is typically needed for this finding.
