RESUMEN
OBJECTIVES: The current report describes the feasibility of robotic retroperitoneal lymph node dissection (RRPLND), including some technical tricks for port placement for both right- and left-sided surgery. METHODS: Patients with advanced stage retroperitoneal disease underwent RRPLND using the 4-arm da Vinci Si Surgical System (Intuitive Surgical, Inc.). In both cases, the field of dissection was an ipsilateral template for lymph node dissection. RESULTS: RRPLND in such configuration was safe and effective in both cases. The illustrated port placement with perpendicular docking of the robot allowed for a wide range of motion with limited external clashing, providing sufï¬cient space for the assistant surgeon. The operative time was 300 min (including docking and console time), with no perioperative complications and short hospital stay. CONCLUSION: The port configuration for right- or left-sided unilateral template RRPLND was feasible, permitting a wide range of motion for the robotic arms and thus facilitating an efficient and safe dissection.

Adrenal myelolipoma is a rare mesenchymal tumour with benign biological behaviour that is mainly composed of mature adipose and myeloid tissue. Both sexes are equally affected, most commonly between the fifth and seventh decades of life. The diagnosis of adrenal myelolipoma is mostly incidental. Although it may occasionally be associated with necrosis, rupture and haemorrhage, causing abdominal pain, this tumour is usually asymptomatic. Consequently, management is conservative, while surgical treatment is reserved for symptomatic cases, or for masses growing quickly or to a size >6 cm. Giant myelolipomas (sized >10 cm) are rare. Open radical adrenalectomy is the standard treatment for giant myelolipomas, while the minimally invasive approach has been used in only few cases. We herein report the case of a patient with a giant adrenal myelolipoma who underwent robotic partial adrenalectomy. To the best of our knowledge, this is the largest giant adrenal myelolipoma treated with robotic surgery reported in the literature to date. A 55-year-old male patient underwent an abdominal computed tomography scan during follow-up after radical prostatectomy for prostate cancer Gleason Score 6 (ISUP 1) due to biochemical recurrence. The examination revealed a right hypodense adrenal mass, sized 16×13 cm. Abdominal magnetic resonance imaging confirmed the presence of characteristics suggestive of a myelolipoma. The patient did not report any symptoms. Due to the benign characteristics of the mass, robotic partial adrenalectomy and enucleation of the mass were performed. The operative time and estimated blood loss were 205 min and 100 ml, respectively. No intra- or postoperative complications occurred. The patient was mobilized on the first postoperative day and the time to flatus was 36 h; the length of hospitalization was 4 days. Histological examination confirmed the diagnosis of adrenal myelolipoma, sized 18×11.5×6 cm. No tumour recurrence occurred over a follow-up period of 12 months. In conclusion, robotic surgery allows performing partial adrenalectomy with a lower risk of bleeding and with preservation of healthy adrenal tissue, which is of paramount importance for the patient as it reduces recovery time and the need for medical substitution therapy.
RESUMEN
Pneumoscrotum is the term used to describe the presence of air within the scrotum and includes scrotal emphysema as well as pneumatocele. The etiology varies; in some cases, pneumoscrotum may be due to life-threatening disease like pneumothorax or Fournier gangrene. Despite this, pneumoscrotum is a rarely debated issue. We present two different cases of pneumoscrotum and a review of the literature. The first case report is about a 29 year old male patient affected by Duchenne syndrome who showed pneumoscrotum after cardiopulmonary resuscitation that was performed for asphyxic crisis and cardiovascular arrest. We carried out local puncture with an 18-gauge needle, and the pneumoscrotum was successfully solved. The second case report is about a 56 year old male with pneumoscrotum due to Fournier gangrene who underwent radical exeresis of all necrotic tissues and drainage. This is why most of the scrotal skin and all of the penis skin were removed; as a result, the testicles, epididymis, and cavernosa corpora were externalized. On postoperative day one, the patient was feverless and underwent hyperbaric chamber therapy. No postoperative complications occurred. Accurate evaluation of the pneumoscrotum is always needed. Despite the benign course of most of the clinically evident pneumoscrotum cases, this condition should never be underestimated.
