Summary

Data of patients treated with pancreaticoduodenectomy in 21 hospitals from January 2014 to December 2019 were retrospectively collected and classified to Chen's group, duct-to-mucosa group and invagination group according to different pancreaticojejunostomy. Propensity score matching analysis was performed to balance the baseline differences among three groups. The surgical outcomes were compared. Independent risk factors for postoperative pancreatic fistula were confirmed by logistic regression analysis, and subgroup analysis was also conducted.

Conditions

  • Pancreaticoduodenectomy

Interventions

PROCEDURE

Chen's U-suture technique

Initially, an approximately 2 cm cut edge of the pancreas remnant was mobilized and a incision of the jejunal loop was conducted slightly shorter than the pancreatic remnant. Using dual-needle 3-0 prolene suture for anastomosis, needle A went through the entire intestinal wall from the posterior wall about 1.5 cm away from the resection margin of the jejunum loop, then went through the superior boarder of the pancreas from posterior to anterior. To suture the anterior wall of the jejunum loop, the stitch next entered from the resection margin of the jejunum loop and kept it within the seromuscular layer from proximal to distal, and got out from about 1.5 cm away from the resection margin. Needle B repeated the aforementioned procedures with a parallel distance about 1.0 cm between needle A. Generally, the whole anastomosis needed two to four identical stitches. The stitches should overlap each other to reduce pancreatic leakage. Once all the stitches were finished and tighte

PROCEDURE

invagination

Firstly, using 3-0 silk sutures, the pancreatic capsule and the serosa of the jejunal loop were anastomosed interruptedly to constitute the posterior outer layer of the anastomosis. Secondly, a jejunotomy with an appropriate size was performed and the inner layer (including posterior and anterior) of invagination was formed by two 5-0 prolene sutures with a continuous running between the pancreatic parenchyma and the full-thickness jejunum. Thirdly, the anterior outer layer was sutured in line with the first step.

PROCEDURE

Duct-to-Mucosa

Briefly, Duct-to-Mucosa should make a opening matched to the pancreatic duct and was also performed by two layers. One was the outer layer in both the anterior and posterior walls of the anastomosis which were formed by interrupted 3-0 silk sutures betweent the pancreatic capsule and the jejunal serosa. The other was the inner layer performed in eight to twelve stitches from pancreatic duct to jejunal mucosa with 5-0 prolene sutures.
