Risk factors for complications after robotic adrenalectomy: a review.

The application of adrenal surgery has been spreading steadily in recent years. With the increased use of robotics in surgery, robotic adrenalectomy (RA), especially for the posterior retroperitoneoscopic approach, has been taken on by many high-volume institutions as a good option over the standard laparoscopic approach (LA). This paper reviews the recent literature from May 2010 up to November 2019 with the aim of analyzing RA complications in order to identify risk factors for complications after RA. We analyzed 7 principal risk factors for complication: body mass index (BMI), age, tumor size, tumor side, pathology, previous surgery, and surgeon experience. In the review, some studies identified tumor size, malignancy type, completion of learning curve and, and less clearly, previous ipsilateral upper mesocolic or retroperitoneal surgery, as risk factors for postoperative complications and failure of robotic surgery. Whether RA is meaningfully superior to the standard minimally invasive approach is still a subject of discussion. RA appears safer by virtue of its reduction in hospital stay, lower blood loss, and equivalent complication rates, and surgeons should prefer adrenalectomy over the LA. Despite these advantages, the operative time and the overall cost of the robotic procedure are higher than the LA. Further high-quality trials, especially those analyzing the specific risk factors for complications in robotic surgery, should be conducted in order to optimize the stratification of patients eligible for robotic surgery.
