[Minimally invasive adrenalectomy with posterior retroperitoneoscopy]

Authors report a total of 14 adrenalectomies performed from a posterior (lumbotomy) approach, using minimally invasive retroperitoneoscopic technique. The "UltraCision" scalpel, an ultrasound activated cutter-coagulation device has been used for operative tissue dissection. Two cases were converted. The mean operating time of the successful 12 cases were 128 minutes. No mortality and no septic complication occurred. The mean operative blood loss of the 12 procedures were less than 100 ml. The mean hospitalisation was 3-5 days, and the complete recovery needed 2-3 weeks. On the basis of our own experiences and the ones of prospective, randomized clinical studies of the literature, the retroperitoneoscopic adrenalectomy from a posterior approach is recommended for the surgical treatment of benign tumours of the suprarenal gland with a size less than 5 cm diameter. The low conversion- and complication-rate, the minimal operative blood loss, the short hospitalization and quick recovery time all are the advantages of this method. It can be performed after previous abdominal operation and in cases with morbid obesity. The technique is suitable for bilateral adrenalectomies as well. This method is not justified for the removal of malignant and/or larger than 5 cm adrenal tumours. Coagulopathies are contraindications.
