The use of laparoscopy in retroperitoneal pathology.

Laparoscopy is usually not performed for retroperitoneal disease. However, if the retroperitoneal process is palpable or displaces viscera, laparoscopy may allow visualization and directed biopsy. In a personal series of 316 laparoscopies reviewed retrospectively, 19 (6%) were performed primarily for retroperitoneal pathology. All patients had CT scans documenting a retroperitoneal process. A confirmed histologic diagnosis was obtained on directed laparoscopic biopsy in 16 patients, including 9 non-Hodgkin's lymphomas. There was no mortality or morbidity in this series. Laparoscopy is a useful modality in selected patients with retroperitoneal diseases, and its use should be considered when a histologic diagnosis is necessary.
