Clinical application of pancreatic-duct-jejunum end-to-side continuous suture anastomosis in total laparoscopic pancreaticoduodenectomy.

BACKGROUND

To present a new pancreaticojejunostomy technique for laparoscopic pancreaticoduodenectomy (LPD) and to evaluate its safety and reliability.

METHODS

The data of 120 patients who underwent LPD at a single centre from October 2017 to October 2019 were retrospectively analysed. Of these patients, 71 received continuous suture pancreaticojejunostomy, and 49 received "8-character" suture pancreaticojejunostomy for LPD. We compared and analysed the operation time, anastomosis time, and incidence of postoperative complications between the patients in the two groups.

RESULTS

All operations were successfully performed, with no transfer to open surgery. The operation time and anastomosis time in the continuous suture group were lower than those in the "8-character" suture group (305.8 ± 60.7 min vs. 354.3 ± 69.1 min; 28.6 ± 6.3 min vs. 39.4 ± 11.9 min P < 0.001), and the postoperative hospital stay was also shorter (12.9 ± 3.8 days vs. 15.4 ± 5.8 days P < 0.05) in the continuous suture group. There was no significant difference in the pancreatic duct diameter or intraoperative blood loss between the two groups. There was also no significant difference in the incidence of a pancreatic fistula between the continuous suture group and the "8-character" suture group. The data of patients in the continuous suture group with pancreatic duct diameters < 3 mm and ≥ 3 mm were statistically analysed. There was no significant difference in the operation time, pancreaticojejunostomy time, postoperative hospital stay, or incidence of pancreatic fistula in the different pancreatic duct diameter groups.

CONCLUSIONS

Continuous suture of pancreaticojejunostomy in LPD is simple, safe, reliable, and rapid. This technique not only saves the anastomosis time but also suitable for pancreatic ducts < 3 mm.
