Popis: Background: The morbidity and mortality of open lung biopsy was assessed, and the ability to provide a specific diagnosis in the assessment of patients with diffuse radiographic pulmonary infiltrates was determined. Methods: A retrospective analysis was undertaken from January 1990 to May 1995 of all patients undergoing open lung biopsy during the study period. A total of 127 biopsies were performed. The indications were diffuse, infiltrative or multinodular disease. Forty-two (33%) patients had previously undergone non-diagnostic trans-bronchial biopsy. Results: Open lung biopsy obtained a histological diagnosis in 121 (95.3%) patients. Postoperative in-hospital mortality was 4.7% (six patients). Three of the four patients being ventilated at the time of biopsy died. Thirty-six (28.3%) patients suffered one or more morbid events. Patients with decreased lung function, as measured by forced expiratory volume, experienced a higher risk of a morbid event (P < 0.01). There was no significant correlation between the chance of a morbid event and age, sex or the use of multiple biopsy sites. A presumptive diagnosis was made prior to biopsy in 71 patients (55.9%) and was proven correct in 43.6% of cases. Conclusions: Open lung biopsy in patients with diffuse pulmonary disease is an accurate diagnostic tool and has an acceptable morbidity and mortality associated with the procedure.
