Abstract

Pancreatic fistulas are relevant in perioperative outcome, morbidity and mortality after pancreatic head resection. We analysed the potential benefit of an internal pancreatic duct draining technique by a resorbable monofilament suture if performing a two-layer duct-to-mucosa pancreatojejunostomy.From 2006 to 2010, 139 pancreatic head resections were performed in our department (124 pylorus-preserving, 15 Whipple). Indications for surgery were malignancies (n = 97), chronic pancreatitis (n = 24) or others (n = 18). In 64 cases, internal drainage of the pancreatic anastomosis was performed as described. Perioperative results were evaluated by the ISGPF classification (International Study Group for Pancreatic Fistula, type A-C) and Accordion classification (degree 1-6).Pancreatic anastomosis was performed in 99 cases as pancreatojejunostomy and in 41 cases as pancreatogastrostomy. Morbidity (Accordion 1-6) was 48 %, and mortality was 5.8 %. Pancreatic fistulas (A-C) occurred in 27 (19.4 %) cases. Only one patient died as a direct consequence of a pancreatic fistula (type C fistula after pylorus-preserving pancreatic head resection and pancreatogastrostomy). In the subgroup of patients with a two-layer duct-to-mucosa pancreatojejunostomy with internal pancreatic duct drainage by a resorbable monofilament suture (n = 64), a pancreatic fistula occurred in 20.3 % (n = 13). According to the ISGPF classification, they were type A (n = 10), type B (n = 2) and type C fistulas (n = 1). In this subgroup with pancreatic duct drainage, morbidity (Accordion 1-6) was 55 % (n = 35) and mortality (Accordion 6) was 6.2 % (n = 4). Complications due to the pancreatic duct drainage were not observed.Internal drainage of the duct-to-mucosa pancreatojejunostomy using monofilament suture material is a safe and feasible method. Pancreatic fistula occurred in 20 % both in the entire group as well as in subgroups with or without pancreatic duct drainage. A reduction of the rate of pancreatic fistula could not be achieved by internal drainage of the pancreatojejunostomy.Georg Thieme Verlag KG Stuttgart · New York.
