Gastric outlet obstruction (GOO) is a rare diagnosis that can be challenging to make as its symptoms, which include abdominal distention, nausea, and persistent vomiting, often overlap with many other acute abdominal pathologies. Point-of-care ultrasound (POCUS) can help the clinician identify gastric outlet obstruction in patients who present to the emergency department (ED). Sonographic identifiers include a markedly dilated stomach that is filled with both hyper- and hypoechoic contents and may extend into the lower abdomen in the pelvic views.
胃出口梗阻（GOO）是一种罕见的诊断，因其症状（包括腹胀、恶心和持续性呕吐）常与许多其他急性腹部疾病重叠，所以诊断起来可能具有挑战性。床旁超声检查（POCUS）有助于临床医生识别出现在急诊科（ED）的患者是否存在胃出口梗阻。超声检查的特征包括胃明显扩张，内有高回声和低回声内容物，在盆腔视图中胃可能延伸至下腹部。
