原發性網膜扭轉是兒童急性腹痛的一個罕見病因。它的臨床症狀和急性闌尾炎幾乎無法分辨,因此通常只有在手術時才能診斷出來。有兩位年齡分別是八歲和十三歲的男童,因為急性腹痛就醫,被診斷為急性闌尾炎,但在手術時意外發現是原發性網膜扭轉。手術的方式是將扭轉壞死的網膜切除。兩位病童經手術後,均順利康復。
Primary omental torsion is a rare cause of acute abdomen in children. Its clinical manifestations are so close to those of acute appendicitis that a differentiation between the two diseases is usually impossible before operation. We report two males, aged 8 and 13 years respectively, who suffered from acute abdominal pain and underwent laparotomy for presumed acute appendicitis. Torsion with infarction of a segment of greater omentum was the unexpected finding in both cases. Simple resection of the strangulated omentum was performed, and these two patients recovered uneventfully after operation.
