Summary
Post-gastrostomy CT scans reveal common findings like pneumoperitoneum and hematomas. Alert for complications if subcutaneous emphysema or fluid collections are present after feeding tube placement.
Area of Science:
- Radiology
- Gastroenterology
- Surgical Imaging
Background:
- Percutaneous endoscopic gastrostomy (PEG) is a common procedure for enteral feeding.
- Post-procedural imaging is often performed to assess complications.
- Establishing normal imaging findings post-gastrostomy is crucial for accurate diagnosis.
Purpose of the Study:
- To define the spectrum of normal CT findings following percutaneous gastrostomy placement.
- To differentiate expected post-procedural changes from potential complications.
Main Methods:
- Retrospective review of upper abdominal CT scans from 18 patients.
- Scans were obtained 1 hour to 9 days after percutaneous gastrostomy.
- Analysis focused on identifying common and abnormal post-procedural findings.
Main Results:
- Pneumoperitoneum was observed in 56% of patients.
- Abdominal wall hematomas occurred in 33%, and gastric hematomas in 17%.
- No significant abdominal fluid collections were noted, except in one patient with ascites.
Conclusions:
- Pneumoperitoneum and hematomas are common, expected findings after percutaneous gastrostomy.
- Subcutaneous emphysema, free peritoneal fluid, or loculated collections warrant investigation for complications.
