Technical details of robotic pancreatojejunostomy using a modified Blumgart anastomosis: Thread manipulation using gauze and an assisted port

摘要

BACKGROUNDS: Pancreatojejunostomy is a technically demanding procedure during robotic pancreaticoduodenectomy (RPD). Modified Blumgart anastomosis (mBA) is a common method for the pancreatojejunostomy; however, the technical details for robotic mBA are not well established. During RPD, we performed a mBA for the pancreatojejunostomy using thread manipulation with gauze and an additional assist port. METHODS: Patients who underwent robotic pancreatoduodenectomy at Fujita Health University from November 2009 to May 2023 were retrospectively investigated, and technical details for the robotic-modified Blumgart anastomosis were demonstrated. RESULTS: Among 78 patients who underwent RPD during the study period, 33 underwent robotic mBA. Postoperative pancreatic fistula (POPF) occurred in six patients (18%). None of the patients suffered POPF Grade C according to the international study group of pancreatic surgery definition. The anastomotic time for mBA was 80 min (54-125 min). CONCLUSION: Robotic mBA resulted in reasonable outcomes. We propose that mBA could be used as one of the standard methods for robotic pancreatojejunosotomy.
