Endoscopic transpapillary therapy for disrupted pancreatic duct and peripancreatic fluid collections

Abstract

Eighteen patients with active pancreatic ductal disruptions, including 14 with definable fluid collections, were treated with transpapillary pancreatic duct drains or stents. Twelve of these patients had undergone a previous percutaneous or surgical pancreatic drainage procedure or both, and 8 had long-term drainage tubes in chronic fistulous tracts. Transpapillary catheters could be placed across the ductal disruption or directly into the fluid collection in each case, and 16 of 18 patients had resolution of the disrupted pancreatic duct. Twelve of 14 fluid collections resolved. Complications were limited to mild exacerbation of pancreatitis symptoms in 2 patients and 2 patients who developed subsequent stent occlusion leading to recurrent pancreatitis (1 patient) or recurrent duct blowout with pseudocyst (1 patient). Nine patients had variably significant ductal changes attributable to pancreatic duct stents. At a median follow-up of 16 months, 7 patients ultimately required surgery for ongoing pancreatic pain or residual/recurrent fluid collection. The transpapillary treatment of ongoing pancreatic ductal disruption with or without fluid collection has the potential to obviate surgery in some patients, change an urgent surgical procedure into an elective one, or even assist the surgeon in the performance of intraoperative pancreatography. Further study of this technique appears warranted and must be placed into the perspective of current therapies.
