BACKGROUND: Pancreatic leak after pancreaticoduodenectomy and gut restoration via a single jejunal loop remains the crucial predictor of patients' outcome. Our reasoning that active pancreatic enzymes may be more disruptive to the pancreatojejunostomy prompted us to explore a Roux-en-Y configuration for the gut restoration, anticipating diversion of bile salts away from the pancreatic stump. Our study aims at comparing two techniques regarding the severity of postoperative pancreatic fistula (POPF) and patients' outcome.
METHODS: The files of 415 pancreaticoduodenectomy patients were retrospectively reviewed. Based on gut restoration, the patients were divided into: cohort A (n = 105), with gut restoration via a single jejunal loop, cohort B (n = 140) via a Roux-en-Y technique assigning the draining of pancreatic stump to the short limb and gastrojejunostomy and bile (hepaticojejunostomy) flow to long limb, and cohort C (n = 170) granting the short limb to the gastric and pancreatic anastomosis, whereas hepaticojejunostomy was performed to the long limp. The POPF-related morbidity and mortality were analyzed.
RESULTS: Overall POPF in cohort A versus cohorts B and C was 19% versus 12.1% and 9.4%, respectively (P = 0.01 A vs B + C). POPF-related morbidity in cohort A versus cohorts B and C was 10.5% versus 7.3% and 6.3%, respectively (P = 0.03 A vs B+C). POPF-related total hospital mortality in cohorts A versus B and C was 1.9% versus 0.8% and 0.59%, respectively (P = 0.02 A vs B+C).
CONCLUSION: Roux-en-Y configuration showed lower incidence and severity of POPF. Irrespective of technical skill, creating a gastrojejunostomy close to pancreatojejunostomy renders the pancreatic enzymes less active by leaping the bile salts away from the pancreatic duct and providing a lower pH.
