The gastrointestinal tract is secured in place by various suspensory ligaments. Laxity or incomplete development of these anchoring ligaments can lead to hypermobility and predispose the patient to torsion-related ischemic pathology. A prompt diagnosis is necessary to avoid life-threatening consequences of prolonged visceral ischemia. Abdominal torsions are rarely diagnosed clinically, and it is often the responsibility of the radiologist to recognize and make the diagnosis through radiography, fluoroscopy, or cross-sectional imaging. This article reviews the imaging spectrum (with radiologic-pathologic correlations) and therapeutic implications of gastrointestinal tract torsions.
Torsion-related ischemic pathology may involve any portion of the gastrointestinal tract from the stomach to the colon. The clinical presentation of gastrointestinal tract torsion is nonspecific, and radiologists are relied on to make this diagnosis. Recognition of the predisposing factors and imaging spectrum of gastrointestinal tract torsions is essential to help direct timely intervention in these potentially life-threatening entities.
胃肠道通过各种悬韧带固定在适当的位置。这些锚定韧带的松弛或发育不全可导致过度活动，并使患者易发生与扭转相关的缺血性病理改变。及时诊断对于避免内脏缺血的长期威胁生命的后果至关重要。腹部扭转在临床上很少被诊断，通常需要放射科医生通过放射摄影、透视或横断面成像来识别和做出诊断。本文回顾了胃肠道扭转的影像学表现（包括放射病理学相关性）和治疗意义。
与扭转相关的缺血性病理改变可能涉及从胃到结肠的胃肠道的任何部位。胃肠道扭转的临床表现是非特异性的，需要放射科医生做出诊断。认识胃肠道扭转的诱发因素和影像学表现对于及时干预这些潜在危及生命的疾病至关重要。
