Abstract
Background
Self-expanding metallic stent (SEMS) placement is a valid form of therapy for patients with obstructing colon rectal cancer. The procedure is not feasible for a minority of patients with a very low risk of bowel perforation. This report analyzes the results of a technical detail used for SEMS placement.
Methods
In 43 patients with colon rectal obstruction, the SEMS apparatus was introduced through a guidewire passed above the obstruction in the channel of a pediatric nasogastroscope (diameter, 4.9 mm). The pediatric nasogastroscope was passed into the obstruction and above, allowing the anatomy of the colorectal lesion and the passage of the guidewire to be visualized directly.
Results
The SEMS was inserted successfully in all cases without complications. In a previous series of 82 patients who had passage of the guidewire through the obstruction blindly, four technical failures occurred (nonsignificant difference).
Conclusions
A pediatric nasogastroscope can be useful for passing the colon rectal obstruction and guiding the passage of the guidewire under direct vision.
