Port-site tuberculosis after laparoscopy: report of eight cases.

In light of the explosive increase in laparoscopic surgery, there is concern about the effectiveness of sterilizing reusable laparoscopic instruments by immersion in 2% glutaraldehyde. This article describes the clinical features of eight patients who presented with biopsy-proven tuberculosis at the port-site unassociated with other clinical features of tuberculosis. Three of the eight patients had positive cultures for Mycobacterium tuberculosis. The port-site sinuses healed with antituberculous chemotherapy. There is conflicting information in the literature regarding the effectiveness of a 20-min instrument soak in 2% glutaraldehyde to clear M. tuberculosis. In light of the preceding information, the current practice of glutaraldehyde disinfection for reusable laparoscopes needs to be reexamined.
