Introduction: The safety and efficacy of laparoscopic transperitoneal lateral adrenalectomy and retroperitoneoscopic adrenalectomy have been reported. The aim is to report the authors' experience in laparoscopic left adrenalectomy with an alternative transperitoneal submesocolic and retropancreatic approach with patient supine.
Research methods:The authors have performed laparoscopic transperitoneal submesocolic, retropancreatic adrenalectomy for both benign and malignant, functioning lesions >4cm in diameter or with smaller lesions but having an imaging pattern suspicious of malignancy or of sub-clinically secreting tumors. After opening the posterior peritoneum at the root of the transverse mesocolon and Gerota's fascia, the junction of the inferior adrenal vein with the left renal vein is identified. The adrenal vein is then prepared and divided, followed by mobilization and removal of the left adrenal gland.Conclusion: Early ligation of the adrenal vein is the most relevant technical feature of this procedure to avoid the release of catecholamines, hormones or neoplastic cells which could occur during manipulation of the gland prior to ligation of the main adrenal vein. Moreover, this approach makes it possible to perform associated procedures, including a bilateral adrenalectomy, without the need to reposition the patient on the operative table, but simply by positioning additional trocars.
