Cholecystitis and cholelithiasis should be considered in the differential diagnosis of abdominal pain in children. Ultrasonography should be a primary screening test because it allows rapid evaluation of the gallbladder and identifies other possible causes of the symptomatology. The presence of a thickened gallbladder wall, cholelithiasis, or a nonvisualized gallbladder indicates gallbladder disease. Since acalculous cholecystitis is more common in children than it is in adults, it is particularly important to examine the gallbladder wall carefully for evidence of thickening.
小儿腹痛的鉴别诊断应考虑胆囊炎和胆石症。超声检查应作为主要的筛查手段，因为它能快速评估胆囊情况并找出导致症状的其他可能原因。胆囊壁增厚、存在胆石症或胆囊未显影提示胆囊疾病。由于无结石性胆囊炎在儿童中比在成人中更常见，所以仔细检查胆囊壁是否有增厚迹象尤为重要。
