Natural behaviour and surgical treatment of appendiceal carcinoids: an analysis of 2,376 consecutive emergency appendectomies.

Objective: Carcinoid tumor of appendix is a rare condition. Its rarity may give rise to variances in its management. We aimed to demonstrate the occurrence and form of presentation of carcinoid tumor of appendix, as well as variations in its treatment.
Methods: All appendicectomies that took place between 2000 and 2008 were considered for study.
Results: A total of 2,376 appendicectomies were performed during this period while carcinoid tumours were diagnosed in 27 patients (1.13%). The mean age of patients with carcinoid tumor (26.7 years) was almost the same as that of patients with non-carcinoid pathology (28.1 years). The incidence of male patients was higher than that of females amongst the carcinoid tumor group (female/male ratio: 1/4). None of the carcinoid tumors were identified at operation. One patient (3.7 %) required right hemicolectomy. This patient was followed-up in an inconsistent manner.
Conclusions: Carcinoid tumour of the appendix remains an incidental diagnosis. Patients with carcinoid were significantly younger than those with non-carcinoid conditions in the study. Re-operation rate was low. The interval to definitive surgery was very short and only one patient was followed up. No consideration as to whether the surgery was complete or not was done in the study (Tab. 1, Fig. 1, Ref. 29).
