Neutropenic typhlitis in adults

Area of Science:

• Gastroenterology
• Oncology
• Surgical Pathology

Background:

• Typhlitis, or neutropenic enterocolitis, is a severe necrotizing inflammation of the cecum.
• It predominantly affects neutropenic patients undergoing chemotherapy for various malignancies.
• Risk factors include immunosuppression, poor cecal perfusion, and bacterial presence.

Observation:

• The atonic cecum is particularly vulnerable due to compromised blood supply and bacterial activity.
• Typhlitis is a serious complication but not universally fatal.
• Surgical intervention, specifically resection of necrotic bowel, is often necessary.

Findings:

• Emergency surgery for typhlitis in critically ill patients with unprepared bowels favors a two-stage resection and anastomosis approach.
• Outcomes may differ between adult and pediatric patient populations.
• Increased incidence may correlate with aggressive chemotherapy regimens for leukopenic disorders.

Implications:

• Enhanced physician awareness of typhlitis is crucial, given potential underdiagnosis in adults.
• Early recognition and appropriate surgical management can improve patient outcomes.
• Understanding the pathophysiology aids in developing targeted preventative and therapeutic strategies.
