Incidental neuroendocrine tumours ('carcinoid'), is rare at <1% (5/1237,[1] 20/1350,[2] and 7/1485.[3]), but when found, is commonly at the tip. If at the tip and less than 1-2cm, further intervention is usually not required. There is uncertainty over the indications for a right hemicolectomy, but these may include:[4]
- large tumours (>2cm)
- tumours at the base
- invasion into the mesoappendix
- high-grade histological features
- goblet adenocarcinoid sub-type
