Aim
To conduct a retrospective analysis of the incidence and long-term outcomes of carcinoid tumor of the appendix in emergency appendectomies.
Methods
From a histopathologic database of 2197 appendectomies from a single center, all appendiceal carcinoid tumors were identified and case notes reviewed. Demographic data, clinical presentation, histopathology, operative reports, and survival were scored and compared with those reported in the literature.
Results
Ten patients (0.45%) with appendiceal carcinoid tumor were identified (2 male, 8 female; mean age, 29.2 years; age range, 14–56 years). In all cases, the clinical presentation resembled the symptoms of acute appendicitis. Open appendectomy was performed in all patients. All tumors were located at the tip of the appendix, with a mean diameter of 0.4 cm (range, 0.1–0.9 cm), and the mesoappendix was invaded in one patient. No patient had repeat surgery after the initial operation. After a mean follow-up period of 55 months (range, 26–82 months), all patients were alive and disease- and symptom-free.
Conclusion
To conclude, carcinoid tumors are extremely rare, and the diagnosis is often made after surgery. We emphasise the value of obtaining histopathological analysis of every removed appendix because visual examination does not always correlate with later pathological examination. Furthermore, small appendiceal carcinoids (<1 cm) have an excellent prognosis after appendectomy.
