[Carcinoid tumors of the vermiform process]

An analysis of 11127 appendectomies has been made, among which carcinoid of the appendicular process was revealed in 8 cases. The carcinoid was diagnosed histologically. It is the authors' opinion that determination of the serotonin level in blood and 5-hydroxy-indol acetic acid in urine would permit to judge the activity of the carcinoid process. In case of progressing carcinoid a pararectal incision with a revision of the abdominal organs is recommended. Patients operated upon should be under medical observation.
