Abstract:
Objective To investigate the clinical value of high resolution ultrasound combined with radiological imaging in the diagnosis of Meckel′s diverticulitis (MD),and to analyze the causes of missed diagnosis as well as misdiagnosis by ultrasound.Methods The image data of 61 patients with MD were retrospectively analyzed,the essentials and the causes of missed diagnosis as well as misdiagnosis of ultrasound were summarized and compared with the results of operation,CT,gastrointestinal contrast,as well as radionuclide.Results The patients were divided into simple type(18,29.5%) and complex type(43,70.5%) according to ultrasonography.The simple type diagnostic accuracy rate was 100%,the ultrasonography showed the right lower abdominal tubular bowel shadow or cystic echo mass,and the structure of diverticulum could clearly showed by ultrasound.In another side,the complex type diagnostic accuracy rate was 55.8%,the ultrasonography showed the right lower abdominal mixed echo mass or concomitant with other alimentary tract malformation,while the diverticulum structure was difficult to be distinguished.The diagnostic accuracy rate of radionuclide imaging was 83.6%,CT was 37.0%,while gastrointestinal contrast was 30.0%.Among 19 cases of misdiagnosis by ultrasound,13 cases of MD were confirmed by radionuclide and CT examination,the diagnostic accuracy rate of ultrasound combined with radiological imaging diagnosis was 90.2%.Conclusions The sonographic features of MD are lack of specificity,especially in the complex type,while the patients with recurrent hemafecia or acute abdomen should be alert to the presence of MD.Patients who are suspected of MD by ultrasound diagnosis should also be examined by radiological imaging in order to make an early diagnosis and surgical treatment to improve the prognosis of patients.
