The role of peritoneal biopsy in the diagnosis of ascites.

摘要

Percutaneous biopsies of the peritoneum were obtained in 23 patients with ascites of unknown cause. The only case of tuberculous peritonitis was correctly diagnosed. Peritoneal biopsy provided a diagnosis of malignancy in 6 patients (one lymphoma, one mesothelioma, 4 cases of disseminated carcinoma) but failed to recognize a further 13 cases of disseminated carcinoma. Previous literature is reviewed and the diagnostic usefulness of this procedure is discussed.
