Resection or repair of large peripancreatic arteries during robotic pancreatectomy.

Minimally invasive pancreatic surgery is eventually gaining momentum, but concerns remain regarding the ability to manage challenging operative scenarios. A retrospective review of a prospectively maintained database was performed to identify patients who received arterial resection, or required arterial repair, during robot-assisted pancreatic resection (RA-PR). All procedures were video recorded. Between October 2008 and June 2019, a total of 361 RA-PR were performed. Associated vascular procedures were required in 31 patients (8.5%), including resection or repair of arterial segments in five cases (1.3%): celiac trunk (n = 1), hepatic artery (n = 2), splenic artery (n = 1), and superior mesenteric artery (n = 1). In three patients, an arterial resection was required to manage tumor infiltration. In the remaining two patients, an intraoperative injury demanded arterial repair. All procedures were completed without conversion to open surgery and no patient developed severe complications. At the longest follow-up, all vascular reconstructions are patent. Our results do not call for more liberal use of robotic assistance in borderline resectable or locally advanced pancreatic tumors, but rather emphasize the importance of proper preoperative planning and the need for advanced vascular skills for safe implementation of RA-PR.
