Abstract
Background/Aim: The impact of perioperative fluid management on postoperative morbidity after pancreaticoduodenectomy (PD) remains uncertain. This study aimed to investigate the independent association between perioperative fluid balance (FB) and clinically relevant postoperative pancreatic fistula (POPF) in PD patients. Patients and Methods: A total of 243 consecutive open PD patients were included. Intra- and postoperative FB until postoperative day 3 were calculated, and their predictive performance for POPF was assessed using receiver operating characteristic (ROC) analysis. Propensity score (PS) was estimated as the probability of having higher FB, and factors associated with POPF were identified using crude and PS-adjusted logistic regression models. Results: POPF occurred in 60 patients (24.7%). ROC analysis showed the highest predictive value for total FB on postoperative days 1 and 2, with a cut-off value of 1,585 ml (area under the ROC curve=0.74). Patients with FB ≥1,585 ml had a significantly higher POPF rate (48.3%) compared to those with lower FB (11.0%, PS-adjusted p<0.001). Male sex, body mass index ≥25 kg/m2, non-pancreatic ductal adenocarcinoma, biliary drainage, main pancreatic duct diameter <3 mm, and higher FB showed significant associations with POPF in crude univariate analysis. Higher FB remained a significant factor in both crude multivariate and PS-adjusted analysis [crude multivariate: odds ratio (OR)=8.0; PS-adjusted univariate: OR=4.2; PS-adjusted multivariate: OR=6.1, all p<0.001]. Conclusion: Higher early postoperative FB, a potentially modifiable factor, may be independently associated with increased risk of POPF in PD patients.
