Single-port robot-assisted retroperitoneal surgery: A feasible approach

Abstract

IntroductionThe concept of surgery through a single incision has been pursued in the field of minimal invasion for the treatment of different pathologies. This, added to a retroperitoneal approach, implies less aggression for the patient at different levels. We describe the first cases of single-port robot-assisted retroperitoneal surgery (SP-RARS) in our country using the da Vinci Xi® system. Material and methodsWe present two cases of patients with right adrenal masses larger than 4 cm. The first case was a 55-year-old woman with an incidental diagnosis of angiomyolipoma, and the second case was a 62-year-old man with a non-functioning adrenal adenoma. Both cases were operated through a single 4-cm subcostal incision using the da Vinci Xi® system, annulling arm 4 without reallocating laterality on the surgeon’s console. ResultsBoth surgeries were performed with console times of 75 and 150 min, respectively, with access and docking times below 30 min. Bleeding was less than 100 cc in both surgeries without the need to make accessory incisions or leave a drainage tube. The surgical specimens were removed through the same initial incision without the need for enlargement. Postoperative intravenous analgesia was not necessary in any case (VAS 0) and hospital stay was less than 24 h in both patients without reporting any complications. ConclusionsSP-RARS is a feasible approach using the da Vinci Xi® system.
