Purpose: To evaluate ultrasonographic accuracy in the differentiation of a bezoar from feces in a @entity1744 showing feces-like material just proximal to the transitional zone in abdominal computed tomography (CT). Methods: This study included 14 @entity1 who showed feces-like material just proximal to the transitional zone, among 302 @entity1 diagnosed with @entity1744 on abdominal CT. Ultrasonographic findings such as posterior acoustic shadow and twinkling artifact were considered the diagnostic signs of a bezoar. The diagnostic performance was assessed by comparing these with a clinical diagnosis, which was confirmed by surgery or symptomatic improvement. Results: Among the 14 @entity1 , seven were ultrasonographically diagnosed as having a bezoar, and five of them were surgically diagnosed as having a phytobezoar. Two @entity1 diagnosed as having a bezoar showed complete symptomatic improvement before surgery. The seven @entity1 for whom having a bezoar was ruled out ultrasonographically conservatively treated. Among them, six @entity1 showed symptomatic improvement, suggesting the absence of a bezoar. The seventh @entity1 was confirmed as adhesive band-induced @entity3885 . In all @entity1 , the ultrasonographic diagnosis agreed with the clinically confirmed diagnosis. Conclusion: Ultrasonography is an accurate method for the differential diagnosis of feces-like material just proximal to the transitional zone in abdominal CT. It can help radiologists to quickly and easily diagnose a bezoar.
