Prediction of Small Bowel Obstruction Caused by Bezoars Using Risk Factor Categories on Multidetector Computed Tomographic Findings

Figure 2

Phytobezoar in the middle segment of the small bowels causing SBO. (a) Gastrointestinal contrast radiography detected dilatation and fluid collection in the ileum. (b) Supine abdominal radiograph 24 hours after oral angiografin demonstration demonstrated no contrast agent accumulation in the colon which indicates a complete SBO. (c, d) MDCT axial and coronal images of the abdomen revealed a phytobezoar (white arrows) in the middle segment of the ileum and proximal distended bowels with contrast agent filling. (e) MDCT images with CPR clearly show the location of phytobezoar (arrows), proximal distended, and distal collapsed bowels. (f) MDCT with MIP image reveals a filling defect (arrows) at the obstruction site of the ileum and proximal distended small bowels.
