Predictors and outcomes of jejunostomy tube placement at the time of pancreatoduodenectomy

BackgroundClinically relevant postoperative pancreatic fistula and delayed gastric emptying cause substantial morbidity after pancreatoduodenectomy. Per international guidelines, the placement of jejunostomy tubes may be considered for patients at risk for malnutrition, such as those with a high risk for clinically relevant postoperative pancreatic fistula and related complications. This study determined predictors and postoperative outcomes of jejunostomy tube placement.MethodsPatients undergoing pancreatoduodenectomy in 2014 to 2015 were identified using the American College of Surgeons National Surgical Quality Improvement Program and Procedure-Targeted Pancreatectomy Participant Use Files. Multivariable logistic regressions were used to identify factors associated with concurrent jejunostomy tube placement and postoperative outcomes.ResultsOf 3,600 patients, 8.9% underwent jejunostomy tube placement. Patients given a jejunostomy tube were more likely white (odds ratio 1.46, P = .016), to have low preoperative serum albumin levels (odds ratio 2.13, P < .001), to have received neoadjuvant radiotherapy (odds ratio 2.14, P < .001), and to have received an intraoperative transfusion (odds ratio 1.50, P = .004). We observed no association between jejunostomy tube placement and an increasing number of risk factors for clinically relevant postoperative pancreatic fistula (P = .96) or delayed gastric emptying (P = .54). Overall, jejunostomy tube placement was associated with increased morbidity (odds ratio 1.34, P = .020) and duration of stay (P < .001), but not mortality (P = .12). Among patients with low serum albumin or those who developed clinically relevant postoperative pancreatic fistula or delayed gastric emptying, jejunostomy tube utilization was not associated with morbidity or mortality.ConclusionJejunostomy tube placement during pancreatoduodenectomy was not driven by risk factors for clinically relevant postoperative pancreatic fistula or delayed gastric emptying, suggesting that practice patterns play a role. Among patients with at-risk preoperative albumin or who developed these complications, jejunostomy tube placement was not associated with worse outcomes, supporting selective utilization per guideline recommendations.
