Background and objectives: ERCP prior to pancreaticoduodenectomy is unnecessary in select patients. When performed, it should be in conjunction with endoscopic ultrasound (EUS) to increase diagnostic sensitivity and allow for metal stent placement. The aim of this study was to determine differences in endoscopic practice patterns at community medical centers (CMC) and a comprehensive pancreaticobiliary referral center (PBRC).
Methods: Retrospective cohort study of all patients seen at a PBRC for endoscopic and/or surgical management of potentially resectable malignant distal biliary obstruction from 1/2011 to 6/2014.
Results: Of 75 patients, 30 underwent endoscopic management at a CMC and 45 were initially managed at our PBRC. ERCP was attempted in 92% of patients. EUS was performed more frequently (100% vs. 13.3 %, P < 0.0001), ERCP was more successful (93% vs. 69%, P = 0.02), and metal stent placement more likely (41% vs. 5%, P = 0.005) at our PBRC compared to a CMC. The majority (81%) of patients undergoing initial endoscopy at a CMC required repeat endoscopy at our PBRC.
Conclusions: Patients who are candidates for pancreaticoduodenectomy frequently undergo ERCP. At a CMC, ERCP is often unsuccessful, is rarely accompanied by EUS, and often requires repeat endoscopy. Our findings support regionalizing the management of suspected pancreatic malignancy into dedicated specialty centers. J. Surg. Oncol. 2016;113:647-651. © 2016 Wiley Periodicals, Inc.
