Narcotic sparing postoperative analgesic strategies after pancreatoduodenectomy: analysis of practice patterns for 1004 patients

Improved post-operative outcomes have been demonstrated in gastrointestinal procedures where a narcotic sparing strategy has been utilized. Data for pancreaticoduodenectomy (PD) patients is limited. This study reviews an institutional database for outcomes based on initial analgesic strategy.1004 consecutive patients who underwent PD at Emory University between 2010 and 2017, were included in the analysis. Patients were divided into groups based on primary analgesic strategy employed: epidural alone (EPI), patient controlled opiate analgesia (PCA), dual (dual-PCA/EPI) and other (non-PCA/EPI). Postoperative outcomes for each group were analyzed utilizing univariate and multivariate linear regression.448 (44.6%) patients were treated with EPI, 300 (29.9%) were given a PCA, 78 (7.8%) had dual-PCA/EPI and 178 (17.7%) had non-PCA/EPI analgesia. On univariate analysis, increased BMI (p = 0.030), PCA use (p 0.001), venous thromboembolism (VTE) (p 0.001), post-operative pancreatic fistula (POPF) (p 0.001) and Ileus/delayed gastric emptying (DGE) (p 0.001) were all correlated with increased LOS. On multivariate linear regression, VTE (b-coefficient 9.07, p = 0.004) POPF (8.846, p = 0.001), Ileus/DGE (4.464, p = 0.004) and PCA use (1.75, p = 0.003) were associated with significantly increased LOS.A primary narcotic sparing strategy is associated with a significantly reduced LOS and lower rates of Ileus/DGE. Mean opiate usage was significantly lower in the EPI and non-EPI/PCA groups.
