Outcomes with Preoperative Biliary Stenting After Pancreaticoduodenectomy In the Modern Era

Background Previous studies have documented increased complications following pancreaticoduodenectomy in patients who undergo preoperative biliary stenting (PBS). However, in the modern era, the vast majority of patients with jaundice are stented. We hypothesized that there is no difference in short-term postoperative outcomes between PBS and no PBS in patient with obstructive jaundice undergoing pancreaticoduodenectomy. Methods We performed an analysis using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) participant use file (2014–2017). Patients who received neoadjuvant chemotherapy and required stenting were excluded from the analysis. A propensity-matched analysis was performed to select obstructive jaundice patients who underwent PBS and those who did not with similar characteristics prior to pancreaticoduodenectomy. Short-term postoperative outcome measures included superficial surgical site infection (S-SSI), deep surgical site infection (D-SSI), hospital length of stay (LOS), postoperative pancreatic fistula (POF), hospital readmission, minor morbidity (Clavien-Dindo I–II), major morbidity (Clavien-Dindo III, IV, V), and 30-day mortality. Results A total of 5851 patients with obstructive jaundice underwent pancreaticoduodenectomy without neoadjuvant chemotherapy. 81.6% underwent PBS. Based on the propensity-matched analysis, 927 patients who received PBS and 927 patients who did not were selected for comparing the outcomes between the two groups. There was no significant difference in outcome measures between the two groups with respect to S-SSI (OR 1.30 , 95% CI = 0.94–1.80, p = 0.12), D-SSI (OR 1.07, 95% CI = 0.81–1.41, p = 0.62), POF (OR 1.11, 95% CI = 0.87–1.42, p = 0.40), hospital readmission (OR 0.99, 95% CI = 0.77–1.27, p = 0.94), minor morbidity (OR 0.91, 95% CI = 0.76–1.11, p = 0.36), major morbidity (OR 0.84, 95% CI = 0.67–1.06, p = 0.14), and 30-day mortality (OR 1.05, 95% CI = 0.57–1.95, p = 0.87). Patients who underwent PBS were more likely to have shorter LOS (RR 0.87, 95% CI = 0.81–0.93, p < 0.0001). Conclusion Contrary to previously reported studies, there was no increased risk of short-term postoperative outcomes after pancreaticoduodenectomy between PBS and N-PBS in a propensity-matched analysis. Preoperative biliary stenting is safe and does not need to be avoided before surgical intervention in patients who present with obstructive jaundice.
