Colorectal stenting: An advanced approach to malignant colorectal obstruction

Figure 1 Self-expandable metallic stent placement for acute left-side malignant obstruction. A: Fluoroscopy showed a malignant stricture with 3 cm length at a rectosigmoid junction. A guide wire was passed through the stricture; B: A 8 cm uncovered stent was successfully inserted and deployed.

Figure 2 Stent in-stent placement for re-obstruction. A: Colonoscopy showed a tumor in-growth in a previously inserted uncovered stent at splenic flexus; B: Fluoroscopy showed a significant narrowing of stent due to the tumor in-growth; C: A guide wire and a stent were inserted sequentially through the previously inserted stent; D: A 10 cm uncovered stent was successfully deployed without complications.
