Abstract
Objective:
To introduce laparoscopic neo-pancreaticogastrostomy (neo-PG) and investigate its application potential in total laparoscopic pancreaticoduodenectomy (TLPD).
Materials and Methods:
We performed a single-center prospective single-arm trial to evaluate the feasibility and safety of neo-PG for its initial application in TLPD. The first 50 patients who were operated by a single surgeon and who underwent TLPD with neo-PG at our institution were recruited. The pre/intra/postoperation data were collected and analyzed.
Results:
Twenty-nine male patients and 21 female patients from May 2022 to March 2023 were included. The mean operation time was 272.60 ± 47.30 minutes. The median PG time was 16 (15, 23) minutes. Six patients had delayed gastric emptying (DGE), and all underwent standard LPD. None of the patients had Grade B/C postoperative pancreatic fistula (POPF) or postoperative hemorrhage, or underwent reoperation. The median length of post-LPD hospital stay was 6 (6, 8) days. None of the patients died within 90 days after surgery. Nineteen cases were pathologically classified as pancreatic lesion, 6 cases as bile duct lesion, 18 cases as duodenal lesion, and 7 cases as ampullary lesion.
Conclusion:
The laparoscopic neo-PG is a simple, safe, and feasible pancreatic anastomosis that can be applied in TLPD. Pylorus-preserving LPD may decrease DGE rate. Further studies involving more surgeons are warranted to prove that our new technique may terminate POPF in TLPD.
