Introduction: Recent evidence shows that microscopic examination of some surgical specimens is not necessary. The aim of this work was to assess the usefulness of routine histopathologicalexamination of appendectomy and cholecystectomy specimens, and its impact on the management of patients. Methods: We reviewed all pathological reports on appendectomy and cholecystectomy specimens studied in our laboratory between January 2008 and July 2009.The frequency of unexpected pathological diagnoses and their impact on management of patients were evaluated. Results: Out of 2.175 appendectomy specimens, 40 (1.8%) revealed unexpected pathological findings, mostly parasitic infestations (23 cases). Apart from parasites, there were only 2 cases with impact on management: one of tuberculosis and another of a mucinous borderline cystadenoma. Unexpected pathological gallbladder findings were present in 14 (1.3%) of 1.039 cholecystectomy specimens: 2 were of in situ carcinoma and 12 of invasive carcinoma; 8 cases with treatment implications had notbeen suspected by the surgeons, and 4 of them were notevident in the macroscopic examination. Conclusions: Incidental histological findings that are relevant to the management of patients are rare but, nevertheless, they indicate that microscopic examination is necessary. Since routine studies are expensive, a more selective approach to histological studies could be proposed.
