Internal hernia is herniation of a viscus, usually in the small bowel, through a normal or abnormal aperture within the peritoneal cavity. Its incidence has been reported to be one to two per cent. Internal hernias are classified based on location, and the hernial orifice can be either congenital or acquired. Paraduodenal hernias are the most common type (53 per cent). Paraduodenal hernia is often a misnomer and is referred to as a mesocolic hernia. Left and right mesocolic hernias are common, while middle and transverse types are rare. We are reporting a rare congenital middle mesocolic hernia presenting as a complete transection of the small intestine due to blunt injury to the abdomen.
内疝是指脏器（通常是小肠）通过腹腔内正常或异常的孔隙发生的疝出。据报道，其发病率为1%至2%。内疝根据位置进行分类，疝孔可为先天性或后天性。十二指肠旁疝是最常见的类型（占53%）。十二指肠旁疝这个名称常常并不准确，实际上常被称为结肠系膜疝。左、右结肠系膜疝较为常见，而中结肠系膜疝和横结肠系膜疝则较为罕见。我们报告了一例罕见的先天性中结肠系膜疝，该病例表现为因腹部钝性损伤导致小肠完全横断。
