Expandable metal stents for benign pancreatic duct obstruction

Gastrointest Endosc Clin N Am. 1999 Jul;9(3):547-54.

Abstract

Among patients with advanced chronic pancreatitis and morphologically demonstrable main pancreatic duct (MPD) abnormalities who are candidates for endotherapy, about two-thirds have a MPD stricture and require stenting to achieve appropriate ductal decompression. The standard stent used in this indication is the plastic stent, which provides a median patency rate of 6 to 12 months. The requirement for stent exchange represents a limitation for the treatment of this relatively young patient population. By analogy with the biliary tract, the authors hypothesize that self-expandable metal stents might offer a long-lasting drainage of the MPD. Several years ago the authors used such stents on an experimental basis to treat patients with MPD strictures. Although routine use of self-expandable metal stents should be discouraged, the authors propose some guidelines for further technical improvement.
