Summary
Gastrostomy tube removal can cause a stomach wall deformity. This finding on upper GI series may mimic other gastric lesions.
Area of Science:
- Gastroenterology
- Radiology
- Surgical Procedures
Background:
- Upper gastrointestinal (GI) series are crucial for diagnosing various gastric conditions.
- Surgical gastrostomy tubes are commonly placed for nutritional support.
- Post-removal changes in the stomach require careful radiological assessment.
Observation:
- Three cases presented with a focal concave deformity along the greater curvature of the stomach.
- The deformity was observed on upper GI series following recent gastrostomy tube removal.
- The gastrostomy tube site was consistently located at the greater curvature.
Findings:
- The observed gastric deformity is likely related to invaginated gastric mucosa.
- This mucosal invagination is intentionally created during surgical gastrostomy tube placement.
- The association between gastrostomy tube removal and this specific deformity is highlighted.
Implications:
- Radiologists and gastroenterologists should be aware of this potential post-surgical finding.
- This deformity may be mistaken for other gastric pathologies, necessitating accurate interpretation.
- Recognizing this benign entity can prevent unnecessary investigations and interventions.
