Bowel anisakiasis is rare, and the incidence and clinical features of this condition remain unclear. Using the Japanese Diagnosis Procedure Combination (DPC) in-patient database, we identified 201 cases of bowel anisakiasis between the months of July and December during 2007 and 2008. More than 70% were males. The average age was 54.5 years. Overall, 102 (50.7%) cases had ileus, 16 (8.0%) had perforation or peritonitis, and 4 (2.0%) had intestinal bleeding. Allergic responses, including urticaria, were found in seven (3.5%) patients. Fourteen (7.0%) cases underwent open surgery. Three (1.5%) underwent colonoscopic removal of Anisakis larvae. The average length of stay in the hospital was 9.6 days. The annual incidence of bowel anisakiasis is estimated to be about 3.0 per 1 million people per year. It is important to continue collecting all available data to monitor the trends of this distressing condition.
肠旋毛虫病较为罕见，其发病率和临床特征尚不清楚。利用日本诊断程序组合（DPC）住院患者数据库，我们在 2007 年 7 月至 12 月期间确定了 201 例肠旋毛虫病病例。超过 70%为男性。平均年龄为 54.5 岁。总体而言，102 例（50.7%）有肠梗阻，16 例（8.0%）有穿孔或腹膜炎，4 例（2.0%）有肠出血。7 例（3.5%）患者出现过敏反应，包括荨麻疹。14 例（7.0%）患者接受了开放性手术。3 例（1.5%）患者接受了结肠镜下取出旋毛虫幼虫。住院平均时间为 9.6 天。估计每年肠旋毛虫病的发病率约为每百万人每年 3.0 例。继续收集所有现有数据以监测这种痛苦状况的趋势非常重要。
