A New Feasible Technique for Polytetrafluoroethylene Suture Buttress-Reinforced Pancreaticojejunostomy (PBRP): Mechanical Analysis and a Prospective, Randomized Controlled Trial

Novel single-layer continuous suture of pancreaticojejunostomy for robotic pancreaticoduodenectomy

BACKGROUND

The best technique for pancreatic anastomosis after pancreaticoduodenectomy (PD) remains controversial, and the procedure for robotic PD (RPD) has not been previously reported. This study aimed to evaluate the safety and feasibility of a novel technique of pancreaticojejunostomy (PJ) for RPD.

METHODS

The demographics and perioperative outcomes of a consecutive series of RPD patients who underwent single-layer continuous suture (SCS) for PJ between September 2018 and November 2018 were analyzed.

RESULTS

Thirty patients were included in the study. Twenty patients had a soft pancreas, and 15 patients had a small main pancreatic duct (MPD) (<3 mm). The mean operative time was 234.1 min, the mean duration of PJ was 14.9 min, and the median estimated blood loss was 100.0 ml. No patients required conversion to laparotomy. Postoperative pancreatic fistula (POPF) included seven cases of Grade A and two cases of Grade B. No case of Grade C POPF occurred. The mean postoperative hospital stay was 12.3 days. No 90-day readmission or mortality was observed. Neither pancreatic texture nor MPD size affected the perioperative outcomes.

CONCLUSIONS

Single-layer continuous suture is easy to perform and is associated with favorable clinical outcomes, regardless of the pancreatic duct size and texture.
