Abstract: Objective： To explore and analyze the clinical manifestations， imaging diagnosis and treatment principles of volvulus. Methods： Retrospectively analysis of clinical data of 12 patients with acute volvulus treated in the emergency department of the Second Affiliated Hospital of Henan University of Science and Technology and the First Affiliated Hospital of Zhengzhou University from May 2014 to February 2018. Results： All the 12 cases of patients underwent multislice spiral CT (MSCT) examination and found different degrees of ascites， of which 6 cases had typical "whirlpool sign". 4 cases had hemorrhagic ascites by abdominal puncture. 5 cases were diagnosed by exploratory laparotomy， 1 with small bowel torsion in primary bowel rotation， 10 with secondary small bowel torsion， 1 with sigmoid colon torsion， and postoperative adhesions in the abdominal cavity was the main secondary causes(9 cases，75%). There were 10 cases of intestinal necrosis of varying degrees， and the torsion angle was 270° to 720° with an average of （320±35）°. 12 patients underwent emergency laparotomy， 10 patients were cured and discharged from the hospital， and 2 patients died. Conclusion： Adult volvulus has the characteristics of acute onset， severe symptoms， early intestinal necrosis， toxic shock， high mortality， and poor prognosis.MSCT examination of the entire abdominal cavity is of high diagnostic value.Early emergency exploratory laparotomy can significantly improve the cure rate of the disease.Timely emergency laparotomy is necessary when the disease is diagnosed and suspected.
