What Is Radiation Proctitis?
Radiation proctitis is inflammation or irritation of the rectal lining that develops after radiation therapy to the pelvic area. Symptoms can appear weeks, months, or even years after treatment and the ICD-10 code is K62.7.
Common Causes and Risk Factors
Radiation therapy for prostate, bladder, cervical, or rectal cancer
High total radiation dose or prolonged treatment courses
He reviews your radiation treatment record (site, dose, timing), asks about rectal bleeding, urgency, pain or epigastric discomfort, and performs a digital rectal exam.
Endoscopic Assessment
Flexible sigmoidoscopy or colonoscopy allows direct visualization of the rectal lining to identify inflammation, telangiectasias, ulcerations, or strictures.
Stool Studies
Laboratory analysis rules out infectious causes and quantifies blood loss with fecal occult blood testing.
Imaging Studies
Pelvic MRI highlights deeper tissue involvement, fistulas, or abscesses.
CT scan evaluates adjacent organs and excludes other pelvic pathology.
Advanced Testing (if needed)
In selected cases, endoscopic biopsy confirms mucosal changes, and anorectal manometry assesses sphincter function when urgency or incontinence is a concern.
