- First description of extended and tailored fluorescence-guided lymphadenectomy during robotic distal pancreatosplenectomy: case report(2023) SURJAN, R. C. T.; SILVEIRA, S. P.; FIGUEIRA, E. R. R.; ARDENGH, J. C.Background: Minimally invasive distal pancreatosplenectomies for the treatment of pancreatic duct adenocarcinoma (PDAC) of the pancreatic body have become a well-established approach. To improve oncologic resection and lymph node (LN) dissection, technical alternatives have emerged on the last few years, such as the radical antegrade modular pancreatosplenectomy (RAMPS). While it is accepted that 12 LNs should be retrieved during distal pancreatosplenectomies, during RAMPS procedure the mean harvest is described to be 21 LNs (range, 11–30). With the objective of performing extended and tailored lymphadenectomies during robotic distal pancreatosplenectomies, we developed a novel technique for LN dissection with the use of real-time near-infrared robotic fluorescence and direct injection of indocyanine green in the pancreas as a contrast agent. Case Description: The patient presented pathologically confirmed PDAC on the body of the pancreas and was submitted to totally robotic distal pancreatosplenectomy. After exposing the pancreatic body and under intraoperative sonography guidance, 1 mL of indocyanine green was injected on the pancreas just proximal to the tumor. Using robotic fluorescence, we could clearly identify the lymphatic drainage of the pancreatic body, in order to perform fluorescence-guided, extended and tailored lymphadenectomy. Operative time was 4 hours and 43 minutes. Forty-three LNs were retrieved. Surgical margin was free from neoplasia. Postoperative period was uneventful. Conclusions: Fluorescence-guided extended lymphadenectomy with intrapancreatic injection of indocyanine green is a novel technique that may improve oncological results and staging during robotic distal pancreatosplenectomies for the treatment of PDAC of the pancreatic body.
- First Robotic Roux-en-Y Gastric Bypass for the Treatment of Refractory Gastroesophageal Reflux Disease in a Patient With Systemic Sclerosis(2023) SURJAN, Rodrigo Canada T.; SILVEIRA, Sergio; FIGUEIRA, Estela R.Systemic sclerosis (SSc) is an immune-mediated disease that results in fibrosis of the skin and internal organs. Refractory gastroesophageal reflux disease (GERD) associated with severe esophageal dysmotility is common in SSc patients, and surgical treatment with usual anti-reflux procedures such as fundoplications is associated with dismal symptomatic relief and postoperative dysphagia. We report the first robotic short -limb Roux-en-Y gastric bypass (RYGB) with a short Roux limb for the treatment of GERD in a patient with SSc with intense esophageal dysmotility. The operative time was two hours. The procedure and postoperative course were uneventful. The patient presented complete relief of gastroesophageal reflux symptoms and no postoperative dysphagia in a two-year follow-up. Therefore, short-limb RYGB is a safe and very effective alternative for the treatment of severe GERD in patients with SSc. The robotic surgical platform may have some advantages compared to conventional laparoscopy.
