Eighteen consecutive patients with intestinal anisakiasis were studied with high-resolution ultrasound (US) and barium studies. US showed markedly thickened bowel loops associated with luminal narrowing, swelling of Kerckring folds, and decreased peristalsis. A small amount of ascitic fluid around the bowel loops was found, and cytologic examinations of the ascites revealed a dense infiltration of eosinophils. Barium studies demonstrated segmental mucosal edema of the small intestine: The most common site was the distal ileum, and the mean length of the edematous lesion was 19 cm. All patients underwent treatment of symptoms without laparotomy, and their symptoms disappeared by the eighth day after onset. Patients with acute abdominal symptoms should be asked about the intake of raw or undercooked fish. If the above US features are found, the diagnosis of intestinal anisakiasis must be seriously considered to avoid unnecessary surgical treatment.
对18例连续性肠异尖线虫病患者进行了高分辨率超声（US）和钡剂检查。超声显示肠袢明显增厚，伴有管腔狭窄、环形皱襞肿胀及蠕动减弱。在肠袢周围发现少量腹水，腹水的细胞学检查显示嗜酸性粒细胞密集浸润。钡剂检查显示小肠节段性黏膜水肿：最常见的部位是回肠末端，水肿病变的平均长度为19cm。所有患者均未行剖腹手术，仅进行了对症治疗，症状在发病后第8天消失。对于有急性腹部症状的患者，应询问其是否食用了生鱼或未煮熟的鱼。如果发现上述超声特征，必须认真考虑肠异尖线虫病的诊断，以避免不必要的手术治疗。
