Neuroendocrine tumors (NETs) arise from hormone-producing neuroendocrine cells found throughout the body. They most commonly develop in the gastrointestinal tract, pancreas, and lungs. NETs can be slow-growing or highly aggressive. Early detection and treatment help improve outcomes and quality of life.
Symptoms vary depending on tumor location and hormone secretion. You may experience:
The precise cause of most NETs is not known. However, several risk factors and associations have been identified:

A perianal fistula is a small, abnormal tunnel that forms between the anal canal or rectum and the skin around the anus, most often developing after an infection or abscess.
Diagnosis typically involves a physical exam by a colorectal specialist and may include imaging tests such as MRI or endoanal ultrasound to map the fistula's course.
Yes. Chronic inflammation from Crohn's disease can lead to the development of recurrent or complex perianal fistulas in affected patients.
Symptoms often include persistent pain or tenderness near the anus, swelling, itching, and drainage of pus or blood from an opening in the skin.
Recovery time varies by procedure, but most patients heal within 4 to 6 weeks. More complex cases or additional therapies may extend this timeline.
Antibiotics can help control infection and reduce inflammation but usually are not sufficient to close the fistula, which often requires a surgical approach.
Spontaneous healing is rare. Most fistulas persist and require medical or surgical intervention to fully close and prevent complications.
If you experience ongoing pain, swelling, drainage, or suspect a fistula, schedule an evaluation with a gastroenterologist or colorectal surgeon promptly.
In some cases, seton placement to maintain drainage and biologic medications (especially for Crohn's-related fistulas) can manage symptoms without immediate surgery.
Yes. While many patients achieve lasting healing, fistulas can recur. Regular follow-up care and, when indicated, medical therapy help minimize the risk.
