OBJECTIVE: The objective is to use multidetector computed tomography (MDCT) to differentiate @entity3355 and small-bowel faeces in @entity1 with @entity1744 ( @entity1744 ). METHODS: We retrospectively reviewed 91 consecutive @entity1744 @entity1 with surgically proven phytobezoars (n   =   31) or adhesion with small-bowel faeces (n   =   60). Two readers blinded to the diagnosis recorded the following MDCT features: degree of obstruction, transition point, mesenteric fatty stranding, intraperitoneal fluid, air-fluid level, @entity14515 , and portal venous gas. MDCT measurements of the @entity6766 length, attenuation, luminal diameter, and wall thickness of the obstructed bowel were also compared. RESULTS: A higher grade of obstruction with an absence of mesenteric fatty stranding and intraperitoneal fluid was more commonly seen in the phytobezoar group than in the small-bowel faeces group (p   <   0.01). The @entity6766 length (phytobezoar, 5.7        2.8  cm; small-bowel feces, 20.3        7.9  cm, p   <   0.01) and mean attenuation (phytobezoar, -59.6        43.3 Hounsfield units (HU); small-bowel faeces, 8.5        7.7 HU, p <0.01) were significantly different between the two groups. The ROC curve showed that @entity6766 length <9.5  cm and mean attenuation value   <   -11.75 HU predicted @entity3355 . CONCLUSIONS: MDCT features with measurements of the @entity6766 length and mean attenuation assist the differentiation of @entity3355 and small-bowel faeces. KEY POINTS:     MDCT examination helps to differentiate phytobezoar and small-bowel faeces.     A higher grade of obstruction is commonly associated with @entity3355 .     Mesenteric fatty stranding and intraperitoneal fluid are frequently associated with small-bowel faeces.     Quantitative measurement of the obstructed bowel adds the diagnostic accuracy.
