Walled-off pancreatic necrosis (WOPN) represents a late complication of severe acute pancreatitis, with a high mortality rate. Its management depends on the patient's symptoms and WOPN location. The da Vinci surgical systems have been developed to allow an easier mini-invasive surgery, also in challenging abdominal procedures. We present here a case of a WOPN treated with a robotic trans-gastric drainage using da Vinci Xi platform. Methods: A 63-years old man with acute necrotizing pancreatitis was referred to our center. The patient developed a massive fluid collection causing gastrointestinal obstruction. The CT-scan 6 weeks after the acute episode confirmed the presence of a walled-off pancreatic necrosis compressing the stomach and the first duodenal portion. The patient was surgically treated using the da Vinci Xi platform. Results: Surgery was successfully completed in 130 min. An intraoperative US-guided anterior ideal gastrotomy was first performed. Then, through the gastrotomy, the best location for drainage on the posterior gastric wall was US-guided identified. The anastomosis between the posterior gastric wall and the walled-off necrosis wall was performed with the new EndoWrist stapler. Necrosectomy and toilette were performed through the anastomosis. Finally, the anterior gastrotomy was closed with triple layer 3-0 V-Lock running suture and cholecystectomy was done. No conversion or intra-operative complications occurred and the postoperative course was uneventful. A post-operative TC scan showed the collapse of the fluid collection.
