Our goal was to assess the incidence of retropsoas positioned large or small bowel in the population and to examine factors predisposing to its formation.
The presence of retropsoas positioned bowel was retrospectively studied in 1,852 abdominal CT examinations of 1,055 men and 797 women, 648 younger and 1,204 older than 50 years. All examinations were considered normal or demonstrated findings that were unrelated to the position of the bowel.
Retropsoas positioned colon (RPC) was observed in 51 (2.8%) cases for the ascending and 45 (2.3%) for the descending colon. RPC appeared more frequently in younger (< 50 years) than older patients and in individuals with decreased amount of retroperitoneal fat. Retropsoas position of small bowel loops was observed in 11 (0.6%) patients, all exhibiting paucity of retroperitoneal fat.
Because of its prevalence, retropsoas positioned bowel should be considered when performing percutaneous diskectomy or other interventional procedures in the posterior retroperitoneum.
我们的目标是评估人群中腰大肌后位大肠或小肠的发生率，并研究其形成的易感因素。
回顾性研究了1852例腹部CT检查，其中男性1055例，女性797例，年龄小于50岁者648例，年龄大于50岁者1204例。所有检查均被认为正常或显示与肠管位置无关的结果。
升结肠腰大肌后位（RPC）在51例（2.8%）中观察到，降结肠在45例（2.3%）中观察到。RPC在年轻患者（<50岁）中比老年患者更常见，且在腹膜后脂肪量减少的个体中更常见。小肠袢腰大肌后位在11例（0.6%）患者中观察到，所有患者均表现为腹膜后脂肪减少。
由于其发生率，在进行经皮椎间盘切除术或其他后腹膜介入手术时应考虑腰大肌后位肠管。
