Abstract：ObjectiveTo explore the value of different imageological and endoscopy examinations in preoperative diagnosis of Meckel diverticulum, and the reasonable diagnostic flowchart. MethodsFrom January 2008 to December 2018, the data of imaging and endoscopic examinations of 72 patients with Meckel diverticulum confirmed by surgery or endoscopy who were collected from Ruijin Hospital Affiliated to Shanghai Jiao Tong University, Suzhou Hospital Affiliated to Nanjing Medical University, and the First Affiliated Hospital of Soochow University were retrospectively analyzed. The study was grouped according to different ages (children and adults) and symptoms (bleeding and abdominal pain), and the diagnostic rates of different examinations were compared. ResultsThe diagnostic rates of radionuclide scintigraphy, digital subtraction angiography, non-enhanced CT, contrast enhanced CT, computed tomography enterography (CTE), capsule endoscopy (CE) and double-balloon enteroscopy (DBE) were 50.00%(3/6), 12.50%(1/8), 7.14%(1/14), 14.29%(1/7), 57.45%(27/47), 16.00%(4/25) and 95.83%(46/48), respectively. The diagnostic rate of CTE was higher than that of other CT methods (all P＜0.05). The diagnostic rate of CTE in bleeding group was higher than that in abdominal pain group (χ2=6.27, P＜0.05), and there was no statistically significant difference between child group and adult group (χ2=0.59, P＞0.05). The diagnostic rate of DBE was higher than those of CE and CTE (χ2=36.54，16.47, all P＜0.01), and the diagnostic rate of CTE was higher than that of CE (χ2=8.13, P＜0.01). ConclusionsThe three kinds of examinations with high diagnostic rate are DBE, CTE, CE successively. The diagnostic rate of CTE is higher than that of other CT methods, and it has a high diagnostic rate in hemorrhagic diverticulum. Reasonable diagnostic flowchart should be used according to different ages and symptoms.
