Postoperative complication rates in patients undergoing pancreaticoduodenectomy remain high although the operation techniques have developed a lot in recent years. There is evidence that restrictive intraoperative fluid therapy could decrease postoperative complication rates but the results of the former studies have been somewhat controversial. The aim of this study is to examine whether the intraoperative and postoperative fluid therapy affect to the postoperative complication rates in patients undergoing pancreaticoduodenectomy.

The study is a retrospective cohort study. The first cohort consists of patients who underwent pancreaticoduodenectomy in year 2015 when intraoperative fluid therapy were managed using goal directed fluid therapy technique. The second cohort consists of patients who underwent pancreaticoduodenectomy in year 2017 when intraoperative fluid therapy were based on the consideration of the anaesthesiologist. In 2015 most of the patients spent the first postoperative night in the ICU where the fluid management and monitoring of the urine output and vital functions were more controlled than in the normal ward. In 2017 most of the patients got in the regular ward right after the surgery. The aim of the study is to examine whether there are differences in the amounts of the intraoperative and postoperative fluids between the cohorts and does the perioperative fluid therapy affect to the complication rates.

All patients who have underwent pancreaticoduodenectomy in years 2015 and 2017 are counted in the study.
