Adult intestinal malrotation with midgut volvulus is rare and most often diagnosed on abdominal imaging. Once the diagnosis is made, prompt surgical intervention is necessary. A finding suggestive of malrotation with midgut volvulus on abdominal imaging is the "whirlpool" sign where the superior mesenteric vein and superior mesenteric artery twist at the root of the abdominal mesentery. This sign was once thought to be pathognomonic, but recent studies have shown that it can be seen in asymptomatic patients.
A 20-year-old female presented to our emergency department with diffuse abdominal pain. Computed tomography demonstrated the "whirlpool" sign with a concern for malrotation with midgut volvulus. Surgical consultation was obtained and the patient was rushed to the operating room for an exploratory laparotomy. Normal mesenteric attachments were seen and no significant pathology was identified during the laparotomy. The patient was eventually diagnosed with gastritis and discharged in stable condition.
Emergency physicians and surgeons alike should be cautious in confirming malrotation with midgut volvulus solely due to the "whirlpool" sign on abdominal imaging. Premature diagnostic closure can lead to unnecessary procedures and interventions for patients as in the case we report here.
成人肠旋转不良合并中肠扭转较为罕见,多数通过腹部影像学检查确诊。一旦确诊,需立即进行手术干预。腹部影像学检查中提示肠旋转不良合并中肠扭转的一个表现是“漩涡”征,即肠系膜上静脉和肠系膜上动脉在肠系膜根部扭转。此征象曾被认为具有特异性,但近期研究表明,无症状患者也可能出现。
一名20岁女性因弥漫性腹痛就诊于我院急诊科。计算机断层扫描显示“漩涡”征,考虑存在肠旋转不良合并中肠扭转。遂请外科会诊,患者被紧急送往手术室进行剖腹探查。术中可见肠系膜附着正常,未发现明显病变。该患者最终被诊断为胃炎,病情稳定后出院。
急诊医生和外科医生在仅凭腹部影像学检查的“漩涡”征确诊肠旋转不良合并中肠扭转时应谨慎。过早的诊断性结论可能导致患者接受不必要的检查和干预,就像我们在此报告的病例一样。
