Upper Gastrointestinal Stent

• Kim SG

Abstract

Gastrointestinal (GI) stent has been developed for palliation of obstructive symptoms in various diseases causing obstruction of GI tract. Self-expanding metal stent (SEMS) has replaced old type of plastic stent, and endoscopic insertion of stent has replaced fluoroscopy-guided insertion. Nowadays, newly-designed SEMSs have been developed for prevention of complications such as stent migration and re-obstruction, and indications of stent recently have been widened into benign conditions as well as malignant obstruction. In this review, the types, method of insertion, indications and clinical outcomes of stent in the upper GI tract would be discussed.

  Fig. 1 Stent insertion. After insertion of guide-wire through the obstructive lesion with or without fluoroscopic guidance (A), stent is inserted through the guide-wire, and proximal end of the stent is placed at 2 cm proximal site of the obstructive lesion (B). Adequate expansion and location of the stent should be confirmed after withdrawing the delivery device (C).

  Fig. 2 Stent obstruction. Tumor over-growth occurs at both ends of a stent (A), and tumor in-growth occurs through the metal meshwork of stent (B).
