Application of split pancreatic duct stent in laparoscopic pancreaticoduodenectomy

Laparoscopic pancreaticoduodenectomy (LPD) is a classic surgical method for diseases, such as tumors at the lower end of the common bile duct, pancreatic head, and benign and malignant tumors of the duodenum. Postoperative pancreatic fistula (POPF) is one of the most serious complications of LPD. To reduce the incidence of grade B or C POPF and other complications after LPD, we applied a split pancreatic duct stent combined with the characteristics of internal and external stent drainage. Between September 2020 and September 2022,12 patients underwent placement of the Split pancreatic duct stent during LPD. Data on basic characteristics of patients, surgical related indicators and postoperative POPF incidence were collected and analyzed. The results showed that the average operation time was 294.2 ± 36 minutes, average time for pancreaticojejunostomy was 35.9 ± 4.1 minutes, and average estimated blood loss was 204.2 ± 58.2 mL. Biochemical leakage occurred in 2 patients (16.7%), whereas no grade B or C POPF, 1 case (8.3%) had postoperative bleeding, and no death occurred within 30 days after the operation. Preliminary experience shows that the split pancreatic duct stent can effectively reduce the incidence of complications after LPD, especially grade B or C POPF.
