OBJECTIVES: To evaluate the thoraco-abdominal approach for resection of retroperitoneal tumours, as this approach is rarely used because, although exposure is excellent, morbidity is presumed to be increased. PATIENTS AND METHODS: From October 2003 to September 2005, 21 patients (six female, 15 male), aged 14-76 years, underwent resection of very large and/or T4 retroperitoneal tumours through a thoraco-abdominal approach. RESULTS: In 16 (76%) patients tumour resection was complete. There were no significant complications during surgery. After surgery, there were complications in six patients (29%), in four of whom there was no long-term impairment. One patient died at 75 days after surgery from a complicated retroperitoneal haematoma. The mean (range) estimated blood loss was 2883 (50-20 000) mL, the intensive-care unit stay was 3.85 (0-30) days and the intermediate-care unit stay 2.6 (0-9) days. With a mean follow-up of 9.6 (1-19) months, 15 patients (72%) are recurrence-free, two (10%) have progressive disease, and four (19%) have died from malignancy. CONCLUSIONS: The thoraco-abdominal approach permits excellent exposure of the retroperitoneum for large and/or T4 tumours, allowing radical surgery in cases considered otherwise inoperable. Additional advantages are the possibilities of early vascular control and easy surgical extension of the procedure. These facts, combined with the reasonable morbidity found in our series, support the integration of the thoraco-abdominal approach in the regular options for urological surgery.
