Secure reconstruction after pancreaticoduodenectomy: Review and improved our continuous duct-to-mucosa anastomosis

Abstract

Abstract Pancreatic anastomotic leakage is the most common major complication after pancreaticoduodenectomy (PD). The incidence of pancreatic anastomotic leak or fistula has declined to less than 20%, and mortality from this complication has decreased to less than 10% in recent years. The ideal surgical procedures to achieve the most secure pancreaticojejunostomy were compared and reviewed. A single-institution and personal experience was retrogradely compared with two periods between 1988 and 2017, which involved 121 patients who were designed to compare the outcome of complications with or without pancreatic stump by four to six sutures before continuous duct-to-mucosa PD. The surgical reconstruction technique was standardized and unique, and the pancreaticojejunal anastomosis was created using the duct-to-mucosa without (group A, n = 62) and with (group B, n = 59) interrupted stump sutures. The rate of grade A pancreatic fistula was 6.9% in group A and 0% in group B (P < 0.05). Postoperative mortality was 0% in group B. No patient underwent reoperative PD due to pancreatic anastomotic leak. The length of stay during admission and after surgery was significant lower in group B, which was due to less complication after surgery. Interrupted suture of pancreatic stump with a continuous duct-to-mucosa end-to-side pancreaticojejunostomy plus external drainage is the best secure method for pancreaticojejunostomy after PD.
