title: [Surgical strategies for accidental detection of appendix carcinoids].
abstract: Carcinoids (neuroendocrine tumors NET) of the appendix are rare tumors and even today mostly detected only postoperatively by histopathology following operations for acute appendicitis or other abdominal procedures. Most NETs of the appendix are located at the tip of the appendix, less than 2 cm in size and non-metastasizing. Secondary right hemicolectomy with lymph node dissection bears a considerable risk of complications compared to simple appendectomy. To decide upon secondary surgery histopathological risk factors, such as grading, invasion of the mesoappendix, and tumor type in addition to tumor localization and size should be taken into consideration. Up to 20% of NETs of the appendix are associated with various neoplasms of the gastrointestinal tract. Follow-up examination should therefore also consider both appendix carcinoids and synchronous or metachronous neoplasms of the gastrointestinal tract.
