Core Tip

Core tip: Bezoar-induced small bowel obstruction (BI-SBO) is a relatively rare clinical condition. BI-SBO exhibits regional and seasonal characteristics. This condition is associated with various predisposing factors. Multi-slice spiral computed tomography planar scanning can reveal intestinal bezoar conditions and changes in the intestinal wall and peri-intestinal conditions. Contrast-enhanced examination can further reveal vascular conditions, such as vascular hyperaemia and arterial blood supply conditions, in obstructed zones.
