Rectal Ulcers: Causes, Treatment, and Cancer Risks - Surgery

More Info

---

Understanding rectal ulcers is crucial, especially when they are identified during procedures like colonoscopy. Your mother's case, where a rectal ulcer measuring approximately 3-4 cm was found, raises several important questions regarding the nature of the ulcer, its potential for malignancy, and the appropriate treatment options.


Common Causes of Rectal Ulcers
Rectal ulcers can arise from various causes, including:
1. Inflammatory Bowel Disease (IBD): Conditions such as ulcerative colitis or Crohn's disease can lead to ulcer formation in the rectum.

2. Infections: Certain infections, including sexually transmitted infections (STIs) or cytomegalovirus (CMV), can cause ulcers.

3. Ischemia: Reduced blood flow to the rectal area can lead to ulceration.

4. Trauma: Physical injury or irritation from bowel movements can result in ulcers.

5. Malignancy: In some cases, ulcers may be indicative of cancer, particularly if they are associated with atypical cells.


Treatment Options
The treatment for rectal ulcers largely depends on the underlying cause. In your mother's case, the pathology report indicates chronic active inflammation and focal glandular atypia, which suggests that the ulcer is not simply a benign lesion. Here are some potential treatment strategies:
1. Medications: If the ulcer is due to inflammatory bowel disease, anti-inflammatory medications, immunosuppressants, or biologics may be prescribed. Antibiotics may be necessary if an infection is present.

2. Surgery: In cases where the ulcer does not respond to medical therapy or if there is a suspicion of malignancy, surgical intervention may be required.

3. Supportive Care: This includes dietary modifications, stool softeners, and pain management.


Cancer Risks
The concern about whether rectal ulcers can become cancerous is valid. The pathology report mentions "focal glandular atypia," which can be a precursor to cancer. While not all ulcers will progress to cancer, the presence of atypical cells warrants close monitoring. The report suggests that if invasive adenocarcinoma is suspected, a rebiopsy is recommended. This is crucial because early detection of cancer significantly improves treatment outcomes.


Monitoring and Follow-Up
Given the findings, it is essential to have regular follow-ups with a gastroenterologist. They may recommend:
- Repeat Colonoscopy: To monitor the ulcer's progression and assess for any changes that might indicate malignancy.

- Biopsy: If there are any changes in the ulcer's appearance or if new symptoms arise, a biopsy may be necessary to rule out cancer.

- Symptom Management: Monitoring for symptoms such as bleeding, changes in bowel habits, or weight loss, which could indicate complications.


Conclusion
In summary, rectal ulcers can be caused by various factors, and their treatment depends on the underlying cause. The presence of atypical cells in your mother's biopsy results raises concerns about the potential for malignancy, necessitating careful monitoring and possibly further investigation. It is crucial to maintain open communication with her healthcare provider to ensure that any changes in her condition are promptly addressed. Regular follow-ups and adherence to treatment plans will be vital in managing her health effectively.
