RESUMO
OBJECTIVE: To explore contemporary drain management practices and examine the impact of early removal following distal pancreatectomy (DP). BACKGROUND: Despite accruing evidence supporting its benefit following pancreatoduodenectomy, early drain removal after DP has yet to be explored. METHODS: The American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) was queried for elective DPs from 2014 to 2017. When possible, data were linked to survey responses regarding drain management from hepato-pancreato-biliary (HPB) surgeons in the ACS-NSQIP HPB Collaborative conducted in 2017. The independent association between timing of drain removal and patients' outcomes was investigated through multivariable analyses and propensity-score matching. RESULTS: Of 5581 DPs identified, 4708 (84.4%) patients received intraoperative drains and early removal (≤ POD3) was performed in 716 (15.2%). Drain fluid amylase was recorded on POD1 for 1285 (27.3%) patients who received drains. The overall rates of death or serious morbidity (DSM) and clinically-relevant fistula (CR-POPF) were 19.5% and 17.0%. Early removal demonstrated significantly better outcomes when compared to late removal and no drain placement for: DSM, CR-POPF, delayed gastric emptying, percutaneous drainage, length of stay, and readmission. On multivariable analysis, early removal demonstrated reduced odds of developing DSM (OR = 0.41, 95% CI = 0.26-0.65) and CR-POPF (OR = 0.33, 95% CI = 0.18-0.61) compared to no drain placement, while late removal displayed increased odds for CR-POPF (OR = 2.15, 95% CI = 1.27-3.61) when compared to no drain placement. After propensity-score matching, early removal was associated with reduced odds for CR-POPF (OR = 0.35, 95% CI = 0.17-0.73). CONCLUSION: Although not yet widely implemented, early drain removal after distal pancreatectomy is associated with better outcomes. This study demonstrates the potential benefits of early removal and provides a substrate to define best practices and improve the quality of care for DP.

OBJECTIVE: The aim of this study was to elucidate the impact of intraoperative blood loss on outcomes following pancreatoduodenectomy (PD). BACKGROUND: The negative impact of intraoperative blood loss on outcomes in PD has long been suspected but not well characterized, particularly those factors that may be within surgeons' control. METHODS: From 2001 to 2015, 5323 PDs were performed by 62 surgeons from 17 institutions. Estimated blood loss (EBL) was discretized (0 to 300, 301 to 750, 751 to 1300, and >1300âmL) using optimal scaling methodology. Multivariable regression, adjusted for patient, surgeon, and institutional variables, was used to identify associations between EBL and perioperative outcomes. Factors associated with both increased and decreased EBL were elucidated. The relative impact of surgeon-modifiable contributors was estimated through beta coefficient standardization. RESULTS: The median EBL of the series was 400âmL [interquartile range (IQR) 250 to 600]. Intra-, post-, and perioperative transfusion rates were 15.8%, 24.8%, and 37.2%, respectively. Progressive EBL zones correlated with intra- but not postoperative transfusion in a dose-dependent fashion (P < 0.001), with a key threshold of 750âmL EBL (8.14% vs 40.9%; P < 0.001). Increasing blood loss significantly correlated with poor perioperative outcomes. Factors associated with increased EBL were trans-anastomotic stent placement, neoadjuvant chemotherapy, pancreaticogastrostomy reconstruction, multiorgan or vascular resection, and elevated operative time, of which 38.7% of the relative impact was "potentially modifiable" by the surgeon. Conversely, female sex, small duct, soft gland, minimally invasive approach, pylorus-preservation, biological sealant use, and institutional volume (≥67/year) were associated with decreased EBL, of which 13.6% was potentially under the surgeon's influence. CONCLUSION: Minimizing blood loss contributes to fewer intraoperative transfusions and better perioperative outcomes for PD. Improvements might be achieved by targeting modifiable factors that influence EBL.
