Duct-to-Mucosa Pancreaticojejunostomy with Less Serosal Stitches: A Different Approach to Well-known Problem.

To describe a new approach (duct-to-mucosa pancreaticojejunostomy with less serosal stiches) for postoperative pancreatic fistula (POPF) in pancreaticoduodenectomy. An observational study. Tepecik Training and Research Hospital, Izmir, Turkey, between January 2019 and May 2020. Medical records of 45 patients, who underwent pancreaticoduodenectomy by the same general surgeon between January 2019 and May 2020, were reviewed retrospectively. Pylorus-preserved pancreaticoduodenectomy was performed for all patients. Duct-to-mucosa PJ with less serosal suture technique was used for all patients in reconstruction after pancreaticoduodenectomy. Definition of the ISGPS was used for the POPF and only grade B and C fistulas were accepted as clinically relevant POPF. Here, the descriptive measures were reported. Seventeen (17) of the forty-five (45) patients were females and median age was sixty- six (66) years. The majority of the underlying disease was pancreatic adoneocarcinoma. Hyperbilirunemia was seen in 15 patients. Median operation time was 360 minutes. Number of patients with pancreatic duct size <3 mm was five. Rate of soft pancreas texture was 33.3%. Lastly, the number of patients that underwent vascular resection or additional organ resection were 6 (13.3%) and 8 (17.8%), respectively. Clinically relevant POPF according to ISGPS was seen in 6 patients (grade B:4 and grade C:2). The most prevalent postoperative complication was surgical site infection at a rate of 40%. There was no POPF related mortality. Two-layer duct-to-mucosa pancreaticojejunostomy with less serosal stitches technique has acceptable pancreatic fistula rates. This technique could be used by surgeons who are faced with challenges with the duct-to-mucosa anastomosis due to aforementioned causes. Large multi-centre randomised future studies are required to confirm these findings. Key Words: Postoperative pancreatic fistula, Surgical technique, Duct-to-mucosa pancreaticojejunostomy, Less serosal stiches.
