The CT diagnosis of gastric,esophageal and intestinal phytobezoar / 实用放射学杂志

ABSTRACT

Objective To explore the diagnostic value of CT for the vegetable stone disease in the stomach,esophagus and small intestine.Methods The clinical data and CT findings of 27 cases confirmed by endoscopy or surgery were analyzed retrospectively. Among 27 cases,6 cases performed contrast-enhanced scan.Results Among 27 cases,18 cases were the gastrolithiasis,6 cases were the intestinal stone disease,1 case was the esophagus stone disease,and 2 cases were the multiple stones of stomach and small intestine.CT missed 7 cases and misdiagnosed 1 case with the rate of missed diagnosis was 25.93%.The lesions were cylindrical or oval shape with mixed density in 27 cases,distinct boundary in 26 cases,sclerotic margin in 22 cases,ethmoid or honeycomb bub-bles in the lesion in 25 cases,no enhancement in 6 cases,and complicated small bowel obstruction in 8 cases on CT images.Conclu-sion The phytobezoars in the stomach,esophagus and small intestine have typical CT findings.Careful analyses can improve its di-agnostic accuracy.
