Abstract:
Objective To explore the CT features of gastrointestinal tract diospyrobezoar and its complications,to improve the recognition. Methods The plain CT scan of 36 patients with gastrointestinal tract diospyrobezoar confirmed by gastroscope and surgery were analyzed retrospectively.Results The number and location of diospyrobezoar showed by CT were consistent with the results of gastroscope and surgery.There were 1 1 cases of stomach diospyrobezoar,1 9 cases of small intestine diospyrobezoar,and 6 cases of stomach and small intestine diospyrobezoar.32 cases were solitary lesion,and 4 cases were multiple lesions.A total of 41 diospyrobezoars were removed, most of which were wel-l defined ovoid mass.3 1 lesions presented mottled internal gas bubbles with high-density encapsulating wall.6 lesions showed mottled gas pattern without encapsulating wall.4 lesions showed uneven high density.Over time,1 lesion moved in the digestive tract and the boundary and density were changed.Complications:gastric and duodenal diospyrobezoar accompanied by gastric retention,which manifested as a significant expansion of the gastric cavity effusion.Small intestine diospyrobezoar was accompanied by small bowel obstruction,which showed that the proximal intestinal tube of the diospyrobezoar was obviously dilated,and the distal intestine was suddenly collapsed.There was a focal transition zone between them.Conclusion Gastrointestinal tract diospyrobezoar has a variety of CT manifestations,of which oval shape,clear boundary,uneven mass composed of gas and soft tissue are common.
