Cecal volvulus （盲肠扭转）

Diagnosis:  Cecal volvulus. (ACR Case #128)                           

【Cecal volvulus 盲肠扭转】

When the ascending colon fails to be fixed to the retroperitoneum of the right abdomen, excessive mobility may occur which can allow for torsion and displacement of the ascending colon into the left upper quadrant.  The term cecal volvulus is somewhat of a misnomer since the point of torsion is usually well above the ileocecal valve.  This abnormality represents approximately 1 to 3% of cases of intestinal obstruction in adults and may occur as a sudden abdominal emergency.  Mobility of the cecum is not uncommon in asymptomatic patients, which suggests that for torsion to occur there may be an underlying precipitating condition.  In approximately one-third of cases there will be evidence of an obstruction distal to the torsion.  

升结肠没有位于右腹膜后，过度移位至左上腹，提示肠扭转。常用的盲肠扭转从某种程度上来说并不准确，因为扭转点常位于回盲瓣之上。该疾病大约占成人小肠梗阻的1-3%，可引发急腹症。无症状的盲肠移位并不少见，盲肠扭转提示潜在的急症。约1/3的患者可在扭转处远端看到梗阻。
