ABSTRACT

Objective To study the diagnosis and treatment of omental torsion.Methods 73 patients with omental torsion from Jan 1995 to Dec 2009 in literatures together with the one we reported were reviewed and analyzed The range of ages was from 3 to 65 years,and the median age was 25.3 years.Among them,35 cases were less than 18 years old(47%,and 27 with obesity) and others more than 18 years old(53%,1 with obesity).The accurate diagnosis before operation exsited in 9 patients.49 patients(66%) were diagnosed as primary omental torsion,and childhood obesity was the most related factor.Conversely,25(34%) were diagnosed as secondary omental torsion,while the most common reason was adhersion.In contrast with other clinical symotoms and signs,abdominal pain and tenderness were occurred in almost every people.Bultro sonography(positive rate24%,6/25) was hardly useful in diagnosis but CT (positive rate96%,23/24) and MRI(positive rate100%,2/2) were beniticial.Operation was applied in all patients,while laparoscopy was uesed in 23 patients.As a rule,the appendix was removed together in 61 persons.The cobort of patients was recoverd fully without serious complications such as hemorrhage and intestinal infarction.Conclusion Omental torsion was a relatively rare disease,and the diagnosis should be easy with the help of CT and MRI,and the laparoscopy was the better choice for surgeons.
