Does Pancreatic Stump Closure Method Influence Distal Pancreatectomy Outcomes?

Background: Pancreatic fistula remains the primary source of morbidity following distal pancreatectomy. Previous studies have reported specific methods of parenchymal transection/stump sealing in an effort to decrease the pancreatic fistula rate with highly variable results. The aim of this study was to determine postoperative outcomes following various pancreatic stump-sealing methods. Study Design: All cases of distal pancreatectomy were reviewed at a single institution between January 2008 and June 2011 and were monitored with complete 30-day outcomes through ACS-NSQIP. Pancreatic stump-sealing method was used to create three operation groups (suture, staple, or saline-linked radiofrequency). Two- and three-way statistical analyses were performed among the operation groups. Results: Two hundred three patients underwent distal pancreatectomy. The most common diagnoses included chronic pancreatitis, adenocarcinoma, and IPMN. The suture, staple, and SLRF groups included 90 (44 %), 61 (30 %), and 52 (26 %) patients, respectively. Overall complications (range 31–38 %) and pancreatic fistula (range 25–26 %) were similar with each pancreatic closure technique. Operative technique was not associated with an increased need for postoperative interventions or hospital readmission. Conclusions: Postoperative outcomes after distal pancreatectomy are unaffected by the use of SLRF sealing of the pancreatic stump when compared to traditional suture or reinforced stapling techniques.
