The Effect of Goal-Directed Fluid Administration on Outcomes After Pancreatic Surgery.

BACKGROUND

We evaluated the effect of an Enhanced Recovery After Surgery protocol on intraoperative fluid administration and postoperative outcomes in pancreatic surgery.

METHODS

Pancreatic cancer resections at our institution from 2012 to 2018 were grouped according to pre- or post-protocol initiation. Preoperative characteristics and postoperative outcomes were compared with Fisher's exact test and chi-square for categorical variables, and Mann-Whitney U test for continuous variables. Further analysis separated patients that had a Whipple from those who had distal pancreatectomy.

RESULTS

A total of 263 patients underwent pancreatic cancer resection during the study period (169 Whipples, 84 DPs, 92 pre-ERAS and 171 post-ERAS). Intraoperative fluid administration significantly decreased after protocol implementation (mean 6,277 ml vs. 3870 ml, p < 0.001). This held true when separating patients that had a Whipple procedure from those that had a DP (6,929 ml vs. 4,513 ml, p < 0.001, 5,060 ml vs. 2,833 cc, p = 0.002, respectively). Intensive care unit (ICU) admission (41.3% vs. 20.5%, p < 0.001) and length of stay (9.4 vs. 8.1 days, p < 0.01) were significantly reduced after ERAS implementation for all patients and in Whipple patients alone (47.5% vs. 23.6%, p = 0.002 and 10.7 vs. 6.6 days, p = 0.004). DP patients also had significantly decreased ICU admissions (41.3% vs. 20.5%, p = 0.045). All other postoperative outcomes were not significantly different.

CONCLUSION

For patients undergoing pancreatic cancer resection, goal-directed fluid management is associated with decreased intraoperative fluid administration, decreased ICU admission, and decreased length of stay without an increase in postoperative complications or readmission.
