Abstract

Background
Chronic non-healing or refractory pancreatic fistulae are rare complications of pancreatic surgery (pancreaticoduodenectomy, distal pancreatectomy) or pancreatitis.
Materials and Methods
We conducted a thorough literature search of electronic databases such as PubMed, Google Scholar, BioMed Central, and Cochrane Library using the keywords and medical subject headings (MeSH) terms “chronic pancreatic fistula”, “post-operative fistula”, “fistula management” and “refractory pancreatic fistula”. The purpose of this review is to evaluate the management options for refractory pancreatic fistula (PF).
Results
Literature reveals that refractory pancreatic fistulae have been managed by techniques like endoscopic ultrasound (EUS)-guided techniques like transmural puncture by clamping, puncture of the fistula tract, transmural placement of pigtail stent, and EUS-guided pancreaticogastrostomy. Other techniques are postoperative endoscopic pancreatic stent placement in Grade C pancreatic fistula, intestinal decompression catheter insertion into the jejunum, embedding fistulojejunostomy, and fistulojejunostomy.
Conclusion
In conclusion, embedding fistulojejunostomy, EUS-guided transmural puncture by clamping, and EUS-guided transmural placement of pigtail stent are effective techniques for the management of refractory pancreatic fistulae. Yet further studies in a larger population are recommended.
