摘      要：AIM To review clinical experience with barium appendicitis at a single *** A retrospective review of patients admitted with a diagnosis of acute appendicitis, from January 1, 2013 to December 31, 2015 was performed. Age, gender, computed tomography(CT) scan findings if available, past history of barium studies, pathology, and the presence of perforation or the development of complications were reviewed. If the CT scan revealed high density material in the appendix, the maximum CT scan radiodensity of the material is measured in Hounsfield units(HU). Barium appendicitis is defined as:(1) patients diagnosed with acute appendicitis;(2) the patient has a history of a prior barium study; and(3) the CT scan shows high density material in the appendix. Patients who meet all three criteria are considered to have barium *** In total, 396 patients were admitted with the diagnosis of acute appendicitis in the study period. Of these, 12 patients(3.0%) met the definition of barium appendicitis. Of these 12 patients, the median CT scan radiodensity of material in the appendix was 10000.8 HU, ranging from 3066 to 23423 HU(± 6288.2). In contrast, the median CT scan radiodensity of fecaliths in the appendix, excluding patients with barium appendicitis, was 393.1 HU, ranging from 98 to 2151 HU(± 382.0). The CT scan radiodensity of material in the appendices of patients with barium appendicitis wassignificantly higher than in patients with nonbarium fecaliths(P 0.01).CONCLUSION Barium appendicitis is not rare in Japan. Measurement of the CT scan radiodensity of material in the appendix may differentiate barium appendicitis from routine appendicitis.
