Pancreaticogastrostomy (PG) is a viable option for selected patients needing a pancreatic anastomosis. The double purse-string technique can facilitate the construction of transgastric PG but in a minimally invasive approach can lead to complications due to lack of tactile feedback. We present an adaptation of double purse-string PG for the robotic surgery, with several modifications. Firstly, the inner purse-string suture is tied through the anterior gastrotomy to improve the approximation of gastric and pancreatic serosae. Secondly, all-around-the-clock intragastric interrupted mattress sutures of e-PTFE are used to secure the pancreatic remnant to the stomach, enhancing improve hemostasis. Thirdly, e-PTFE sutures precise tension calibration due to their elastic properties and resistance to robotic manipulation. Fourthly, retroperitoneal vessels are preemptively covered by passing the pancreatic remnant through a small opening in the omentum, which is rotated upward in the omental bursa. This technique was employed in 20 PGs with no grade C postoperative pancreatic fistula. It offers a viable option robotic pancreatic anastomosis.
