Summary
Carcinoid tumors are rare incidental findings in appendectomies, occurring in 0.56% of cases. Simple appendectomy is an effective treatment, with no recurrences observed in long-term follow-up.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Context:
- Appendectomies are common surgical procedures.
- Carcinoid tumors are a type of neuroendocrine tumor.
- Early detection and treatment are crucial for favorable outcomes.
Purpose:
- To determine the incidence of carcinoid tumors in patients undergoing appendectomy.
- To analyze the clinical presentation and histological types of these tumors.
- To evaluate the efficacy of simple appendectomy as a treatment.
Summary:
- A retrospective study analyzed 2478 appendectomies performed between 1984 and 1991.
- Carcinoid tumors were found in 0.56% of cases, often as incidental findings.
- Histologically, 11 cases were classical type (one with a balloon cell variant), and 3 were tubular adenocarcinoids.
- All patients were treated with simple appendectomy.
- Long-term follow-up (up to 11 years) showed no evidence of recurrence.
Impact:
- Highlights the importance of routine histological examination of all removed appendix specimens.
- Demonstrates that simple appendectomy is sufficient treatment for appendiceal carcinoid tumors.
- Provides evidence for the favorable prognosis of these tumors when treated surgically.
