How Dr. Nghia Nguyen Diagnoses Solitary Rectal Ulcer Syndrome?
Dr. Nguyen uses a step-by-step approach:
Medical History and Symptom Review
He discusses your bowel habits, straining patterns, bleeding episodes, and any past gastrointestinal issues.
Physical Examination
Includes an external and digital rectal exam to check for tenderness, prolapse, or mucosal abnormalities.
Anoscopy or Flexible Sigmoidoscopy
Direct visualization of the rectal lining to identify ulcerations, inflammation, or mucosal prolapse.
Biopsy and Histology
Small tissue samples are taken during endoscopy to confirm SRUS under the microscope and exclude other disorders.
Additional Studies (if indicated)
Defecography or dynamic MRI to assess rectal prolapse or intussusception during evacuation.
Pelvic floor manometry to evaluate muscle coordination and sphincter function.
