The internal paraduodenal hernia is a most unusual disorder of the alimentary tract, due to a failure of the process of intestinal rotation. There exists a right and left variety, each of them presenting specific features. Often there are no symptoms or perhaps a vague abdominal malaise. Occasionnally one finds the clinical picture of obstruction, even of strangulation. The preoperative diagnosis is seldom made; however, it could be done if one keeps the possibility in mind. A successful surgical treatment necessitates an understanding of the mode of origin and a throughout knowledge of the anatomic variations.
十二指肠旁内疝是一种极不常见的消化道疾病，由于肠道旋转过程异常所致。有左右两种类型，每种都有其特定特征。通常没有症状，或者可能仅有轻微的腹部不适。偶尔会出现肠梗阻甚至绞窄的临床表现。术前很少能做出诊断；然而，如果对此有所考虑，是可以做到的。成功的手术治疗需要了解其起源方式并全面掌握解剖变异情况。
