AIM: To report the experience of the CHU Sart Tilman, University of Liège, Belgium, in the management of appendiceal carinoid tumor. METHODS: A retrospective review of 1237 appendecto- mies performed in one single centre from January 2000 to May 2004, was undertaken. Analysis of demographic data, clinical presentation, histopathology, operative re- ports and outcome was presented. RESULTS: Among the 1237 appendectomies, 5 appen- diceal carcinoid tumors were identified (0.4%) in 4 male and 1 female patients, with a mean age of 29.2 years (range: 6-82 years). Acute appendicitis was the clinical presentation for all patients. Four patients underwent open appendectomy and one a laparoscopic procedure. One patient was reoperated to complete the excision of mesoappendix. All tumors were located at the tip of the appendix with a mean diameter of 0.6 cm (range: 0.3-1.0 cm). No adjuvant therapy was performed. All patients were alive and disease-free during a mean follow-up of 33 mo. CONCLUSION: Appendiceal carcinoid tumor most of- ten presents as appendicitis. In most cases, it is found incidentally during appendectomies and its diagnosis is rarely suspected before histological examination. Appen- diceal carcinoid tumor can be managed by simple appen- dectomy and resection of the mesoappendix, if its size is ≤ 1 cm.
