How Dr. Scott Diagnoses Proctitis?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He asks about your symptoms (bleeding, mucus, urgency), sexual history, prior pelvic radiation or infections, and reviews any family history of bowel disease.
Laboratory Tests
Stool studies to rule out infectious causes (bacterial cultures, ova & parasites, C. difficile toxin).
Blood tests including CBC (to check for anemia), inflammatory markers (CRP, ESR), and STD panels if indicated.
Endoscopic Evaluation
He performs a flexible sigmoidoscopy or colonoscopy to directly visualize the rectal lining, assess the extent of inflammation, and obtain biopsies for histology.
Imaging and Advanced Testing (if needed)
Pelvic MRI or CT scan to evaluate complications or rule out other pelvic pathology.
Anorectal manometry or defecography for persistent symptoms of incontinence or outlet obstruction.
Rarely, if the diagnosis remains unclear, targeted biopsy or molecular testing on tissue samples.

Frequently Asked Questions
What is the difference between ulcerative proctitis and ulcerative colitis?
Ulcerative proctitis affects only the rectum, while ulcerative colitis involves larger areas of the colon beyond the rectum.
Is ulcerative proctitis the same as erosive proctitis?
Erosive proctitis specifically refers to visible sores on the rectal lining; ulcerative proctitis may not always show visible erosions.
How quickly will I feel better?
Most patients notice improvement within one to two weeks after starting recommended medications and dietary changes.
Can I stop future flare-ups?
Yes. Adhering to your treatment plan, avoiding trigger foods, and managing stress can help prevent flare-ups.
Will I need surgery?
Surgery is uncommon. The majority of cases respond well to early medical and dietary management, with surgery reserved for severe complications.
How long is recovery after a scope procedure?
Most patients resume normal activities within a day or two following a sigmoidoscopy or colonoscopy.
Where can I learn more about the ICD-10 code for proctitis?
Visit the World Health Organization website and search for code K51.3 to see the official listing for ulcerative proctitis.
