[The useless appendectomy]

The appendectomy is still the most frequent operation in general surgery, being after performed without complete investigation. Because the appendix, through its lymphoid tissue with implication in the immunoglobuline secretion, has an important role in immunitary system criteria were searched to justify the appendectomy and to reduce the number of useless appendectomies, the proportion of the normal appendices being around 15%. Instead the basic triad-fever over 38 degrees C, parietal reaction and leucocitosis over 10.000/ml--measuring of reactive protein C, echography, CT, laparoscopy and antileucocite antibody labelled with TC99, would contribute to a better selection of patients for appendectomy. Surgeon's responsibility regarding the technique and the moment of operation, oblige him to take the proper decision.
