[Surgical diseases of the veriform appendix].

Various diseases can symptomatically resemble appendicitis. It has been proved that luminal obstruction is the most frequent cause of inflammation of the appendix. There are various causes of obstruction, such as scars, foreign bodies, tumors, granulomas, and dysfunction of coecocolon. Every appendix should therefore be histologically examined. The operative indication for appendectomy should not only include the time factor, but also anamnesis, complaints, and clinical presentation. It is inconsiderate to perform appendectomy as a prophylaxis against appendicitis. Finally, it is surprising that there have been almost no experimental studies on pathogenesis of appendicitis.
