[Laparoscopy for suspected appendicitis. Should an appendix that appears normal be removed?]

Abstract

The question whether an appendix found to be macroscopically normal at laparoscopy for suspected appendicitis should be removed remains open to debate. Potential advantages of appendicectomy in all cases include early diagnosis of neoplastic lesions that cannot be detected macroscopically, diagnosis and cure of neurogenic appendicectomy, avoidance of diagnostic confusion in later episodes of abdominal pain, and prevention of appendicitis developing later in life. Therefore, adopting a strategy of always removing the appendix even if it is found to be uninflamed at laparoscopy seems justified as long as it does not imply an increase in postoperative morbidity. We retrospectively studied all patients undergoing laparoscopic appendicectomy in which a "normal appendix" was found and all patients undergoing diagnostic laparoscopy in our hospital during a 7-year period. Our data as well as a critical review of the literature show that removal of the appendix does not increase morbidity compared to simple diagnostic laparoscopy and should always be done when performing laparoscopy for suspected acute appendicitis.
