OBJECTIVE: Assessment of the videoscopic approach to the retroperitoneal space in the vicinity of the kidney and the adrenal gland. DESIGN: Open study. SETTING: University hospital, Belgium. SUBJECTS: 10 patients who underwent 11 operations (adrenalectomy, n = 3, nephrectomy, n = 5, partial nephrectomy, n = 2, and renal cystectomy, n = 1). INTERVENTIONS: Direct CO2 insufflation of the retroperitoneal space in order to obtain a convenient retroperitoneal working space for renal and adrenal surgery. OUTCOME MEASURES: Feasibility, morbidity and mortality. RESULTS: 8 patients were operated on exclusively by the retroperitoneoscopic approach; 2 required the retroperitoneal and transperitoneal routes to be combined to complete an adrenalectomy. No patients required blood transfusion and no patient died. Median postoperative stay was 3 days. CONCLUSION: The CO2 insufflation technique of the retroperitoneum is safe and reproducible. Nevertheless, far from excluding each other, both approaches-laparoscopic and retroperitoneoscopic-are complementary in difficult cases, particularly for adrenal endoscopic surgery and for larger renal lesions.
