To investigate the effect of intermittent valved pancreaticojejunostomy，"Double R" pancreaticojejunostomy and traditional pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy（LPD）.

A total of 75 patients who underwent laparoscopic pancreaticoduodenectomy from January 2019 to March 2021 were prospectively selected as the research objects and divided into three groups according to the random number table method，25 cases in each group. Group A received intermittent valgus pancreaticojejunostomy，group B received "Double R" pancreaticojejunostomy，and group C received traditional pancreaticojejunostomy. The perioperative indicators and postoperative complications of the three groups were observed. SPSS 20.0 software was used for statistical analysis，and χ² test was used for postoperative complications and other counting data. Measurement data such as perioperative indicators were expressed as（

The operation time and pancreaticojejunostomy time in group B were significantly shorter than those in groups A and C（P<0.05）. The length of hospital stay in group A was significantly shorter than that in groups B and C（P<0.05）. There were no significant differences in postoperative pancreatic fistula，gastroparesis，postoperative bleeding and abdominal infection among the three groups（P>0.05）.

Although intermittent valvae anastomosis in LPD prolongs the operation time and pancreaticojejunostomy time，it has advantages in reducing the incidence of pancreatic fistula and shortening the length of hospital stay，which is worthy of clinical promotion.
