ABSTRACT：ObjectiveTo evaluate the diagnostic value of intestinal ultrasound（IUS） for organic lesions i the intestines of patients with chronic abdominal pain or diarrhea.MethodsThe IUS signs in 263 patients with chronic abdominal painor diarhea were retrospectively analyzed.With the endoscopic examination results asthe gold standard， comparison was performed for the IUS signs between the groups with positive and negative endoscopic results，as wellas between the inflammatory bowel disease group and the non-specific intestinal inflammation group of positive cases.Furthermore，the detection rates of IUS in diffrent intestinal segments were analyzed to evaluate the accuracy of IUS in the diagnosis and localization of intestinal lesions.ResultsAmong the 263patients，194（ 73.8% ）and 69 （ 26.2% ）patients were in the groups with positive and negative endoscopic results， respectively. The diagnosis sensitivity，specificity，and accuracy of IUS were 82.0% ， 71.0% ， and 79.1% ，respectively. The proportions of positive IUS signs in the group with positive endoscopic results were higher than that in the group with negative endoscopic results （all P<0.001 ）.The proportions of positive IUS signs in the inflammatory bowel disease group were higher than those inthe non-specific bowel inflammation group（all P< 0.001）.Whenthe lesion was located in the ileum，ileocecal region，and colon，IUS demonstrated good consistency with endoscopic results in locating the lesion（ ，0.686，and 0.601，respectively），with sensitivity and specificity of 82.7% （ 95%CI=75.4%-88.6% ）and 81.5% （ 95%（=73.5%-87.9% ）， 73.7% （ ）and 93.0% （ 95%CI=88.4%-96.2% ），and 68.9% （ 95%CI= （20 （ 58.3%-78.2% ）and 89.6% （ 95%CI=84.1%-93.7% ），respectively.ConclusionsIUS can be used for screning the patients with chronic abdominal pain or diarrhea to detect organic lesions in the intestines.Moreover，itcaneffectively locatetheaffcted intestinal segment，which ishelpful for themonitoring and follow-upof intestinal diseases.
