[Silicosis].

Background: Silicosis is a potentially severe but preventable occupational lung disease caused by inhalation of silica particles. There is a wide application in the usage of silica especially in lesser known industries. This disease has yet not been eradicated due to insufficient application of protective measures.

Outcomes of Self-Expanding Metal Stents in Malignant Colonic Obstruction are Independent of Location or Length of the Stenosis: Results of a Retrospective, Single-Center Series.

Aim: To evaluate the length and location of stenosis in the colon as predictors of technical and clinical outcomes of stent placement in patients presenting with obstructive colorectal cancer.

Methods: A prospective single-center cohort study of patients treated with a colonic stent for malignant obstruction, regardless of stenosis length or location. Stenosis length was assessed globally on the appropriate CT slice as well as by 3D CT reconstruction.
