There is limited evidence on which to base clear indications for right hemicolectomy in patients with a diagnosis of appendiceal carcinoid. Acceptable indications are carcinoids larger than 2 cm in size, any high-grade malignant carcinoid (including those with a high mitotic index), mesoappendiceal invasion, lesions at the base of the appendix with tumour-positive margins, and goblet cell adenocarcinoid tumours.

The diagnostic value of chromogranin-A, urinary 5-hydroxy-indol-acetic acid, and (111)Indium-labeled octreotide scintigraphy seems to be limited in these tumors. Ki67 index appears to predict tumor behavior. Right hemicolectomy may reduce the risk of developing metastases. Chemotherapy may have efficacy in metastatic disease, however, more data are required to determine this and the optimal regimen.

Meta-analysis of randomised controlled trials comparing hand-sewn with stapled OG anastomosis demonstrates that a stapled anastomosis is associated with a shorter operative time but with an increased rate of post-operative anastomotic stricture.
