To summarize 1+ 2 pancreaticojejunostomy used in laparoscopic pancreaticoduodenectomy experience, and to explore its safety and effectiveness.

A retrospective analysis was performed on 22 patients undergoing laparoscopic pancreaticoduodenectomy from Nov. 2016 to Nov. 2018 in Digestive Minimally Invasive Center Second Affiliated Hospital of Baotou Medical College. Twelve patients in the observation group were treated with 1+ 2 pancreaticojejunostomy. The control group ten cases were treated with pancreatic duct jejunum mucosa-to-mucosal anastomosis. The time of pancreaticojejunostomy, operation time, intraoperative blood loss, incidence of postoperative pancreatic leakage, reoperation rate, and postoperative complications were observed in the two groups.

The operation was successfully completed in 22 patients.Pancreaticojejunostomy time: observation group (32.8±4.2) min, control group (39.1±7.4) min, the operation time: observation group (295.8±22.6) min, and control group (318.0±24.8) min, intraoperative blood loss: observation group (165.0 ± 30.6) ml, control group (181.0±25.6) ml, pancreatic leakage in postoperative complications: 3 cases in observation group (2 cases of grade A pancreatic leakage, 1 case of grade B pancreatic leakage, 0 case of grade C pancreatic leakage, 3 cases of control group (2 cases of grade A pancreatic leakage, 1 case of grade B pancreatic leakage, 0 case of grade C pancreatic leakage); 1 case of bile leakage in both groups. There were no postoperative bleeding in the group; no postoperative abdominal infection; 1 case in the observation group of gastric emptying and 1 case in the control group; 0 cases in the observation group of pulmonary infection and 1 case in the control group; There were no deaths in either group during the next 30 days. The statistical results showed that there was a significant difference between the two groups of pancreaticojejunostomy anastomosis time and operation time (P<0.05), There was no statistical difference between the remaining observation indicators between the two groups (P>0.05).

The 1+ 2 pancreaticojejunostomy is safe, accurate, and easy to use in laparoscopic pancreaticoduodenectomy. It is worthy of clinical application and promotion.
