Abstract
PURPOSE: Pancreatic anastomosis reconstruction is one of the most technically demanding and complicated procedures in general surgery. No single technique has been demonstrated to be superior to the others in the prevention of postoperative pancreatic fistula (POPF), and the accumulation of surgical experience is closely related to the quality of this anastomosis. The aim of the current study was to evaluate the feasibility of our simplified technique, single-layer continuous duct-to-mucosa pancreaticojejunostomy. METHODS: A single-center prospective single-arm trial was performed. The first 20 patients who underwent Whipple's procedure with the new technique performed by a single surgeon in our center were recruited. General information, preoperative treatments, risk factors for POPF, and postoperative morbidity of the patients were prospectively recorded and reported. RESULTS: From January to February 2020, 13 male and 7 female patients were included. Ten cases were classified as intermediate/high risk according to validated fistula prediction models. The median operation time was 260 min, including a median pancreaticojejunostomy time of 7.7 min. There were 2 cases (10%) of grade B POPF, and no grade C POPF occurred. The overall morbidity rate was 30%, including 2 cases with severe complications (Clavien-Dindo grade ≥ 3). No patients underwent reoperation, and no patient died within 90 days after surgery. The median length of hospitalization was 11 days. CONCLUSION: Single-layer continuous duct-to-mucosa pancreaticojejunostomy is a simplified and feasible method for pancreatic anastomosis. Further studies are warranted to evaluate the indications or contraindications and efficacy of preventing POPF with our new technique.
