Summary
Endoscopic ultrasound (US) effectively diagnoses mucosal prolapse syndrome (MPS) by revealing characteristic rectal wall thickening. This imaging technique helps differentiate MPS from other rectal conditions.
Area of Science:
- Gastroenterology
- Diagnostic Imaging
Background:
- Mucosal prolapse syndrome (MPS), also known as solitary ulcer of the rectum, presents diagnostic challenges.
- Accurate diagnosis is crucial for appropriate patient management and differentiating MPS from other rectal pathologies.
Purpose of the Study:
- To evaluate the diagnostic utility of endoscopic ultrasound (EUS) for mucosal prolapse syndrome.
- To assess the specific EUS findings associated with MPS.
Main Methods:
- A study involving five patients (3 male, 2 female; age 17-66) with biopsy-proven MPS.
- Endoscopic ultrasound (EUS) was performed on affected rectal areas.
- Rectal wall thickness in affected areas was compared to normal mucosa.
Main Results:
- EUS identified smooth, diffuse thickening of the third rectal wall layer in all MPS cases.
- Other rectal wall layers showed minimal thickening, preserving the five-layer structure.
- Polypoid lesions exhibited winding and thickened third layers, sometimes with microcystic changes.
Conclusions:
- Endoscopic ultrasound (EUS) is valuable in diagnosing mucosal prolapse syndrome.
- EUS findings can help differentiate MPS from malignant neoplasia and Crohn disease.
