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

Figure 1

Trichobezoar in the gastrointestinal tract causing high-level intestinal obstruction. (a, b) MDCT axial images of the upper-middle part of the abdomen demonstrated a large, well-circumscribed, nonhomogeneous lesion (white arrows) in the lumen of the stomach with a tail extending up to the duodenum (black arrow) that was composed of concentric whorls of different densities. This suggests a positive diagnosis for trichobezoar. (c) MDCT coronal image shows the trichobezoar in the stomach cavity extending up to proximal jejunum (arrows). (d) Gastroscopy and surgical operations detected a giant trichobezoar filling about 75% of the stomach cavity, extending through the pylorus and duodenum into proximal jejunum. This is covered with viscous liquid secretions.
