Hernias are a common cause of small bowel obstruction. Many different classifications of hernias exist, all differing by location throughout the abdomen and hernia contents. We present a case report that describes a unique hernia-a peritoneal invagination hernia-which may lead to small bowel obstruction. The peritoneal invagination hernia is a defect in the peritoneum, in this case located on the right anterolateral abdominal wall, allowing small bowel to enter and become incarcerated. In our patient, the peritoneal defect was circular with smooth, rolled borders. The defect contained intact peritoneum overlying intact transversalis fascia. The patient had no prior abdominal surgeries. This hernia differs by location and etiology from preperitoneal interparietal hernias, which are found in the inguinal and femoral regions. This case describes a newly characterized abdominal hernia which is hypothesized to be due to a prior intra-abdominal inflammatory process.
疝是小肠梗阻的常见原因。疝有许多不同的分类，它们在整个腹部的位置和疝内容物方面都有所不同。我们报告一例病例，描述了一种独特的疝——腹膜内陷疝，它可能导致小肠梗阻。腹膜内陷疝是腹膜的一种缺损，在本例中位于右前外侧腹壁，使小肠进入并发生嵌顿。在我们的患者中，腹膜缺损呈圆形，边缘光滑、内卷。缺损处覆盖完整腹膜，其下为完整的腹横筋膜。该患者既往无腹部手术史。这种疝在位置和病因上与腹股沟和股部区域的腹膜前间壁疝不同。本病例描述了一种新发现的腹部疝，据推测其病因是既往的腹腔内炎症过程。
