A and B The 4–0 Vicryl suture completely penetrates the pancreatic stump, then continuously penetrates from the posterior to the anterior wall of the jejunal loop. The same method was used to perform the subsequent 6–8 sutures. The stitch suturing the entire layer of the jejunal wall begins, from proximal to distal, approximately 2–3 cm to the resection margin of the loop. These sutures are preplaced approximately 8–10 mm from the cut edge of the pancreatic remnant and the jejunum, 5 mm between each other, and they are not tied until all 6–8 of the sutures have been placed. The first and last suture should be on the outer edge of the jejunum incision, so as to guarantee the pancreatic stump was completely covered with jejunum serosa
