腹膜后间隙广阔,组织类型繁多,除了肾、肾上腺、胰腺等器官发生的肿瘤以外,腹膜后脂肪,疏松结蒂组织、筋膜、肌肉、血管、神经、淋巴网状组织以及胚胎残余组织等均可以发生不同类型肿瘤。这些肿瘤早期多无明显临床表现,故易与腹腔肿瘤相混淆,给临床诊断带来一定困难。共收治137例腹膜后肿瘤,本文就术前误诊的29例做一简要分析。 The retroperitoneal space is vast and the tissue types are numerous. In addition to the tumors of the kidneys, adrenal glands, pancreas and other organs, the retroperitoneal fat, loose junction tissue, fascia, muscle, blood vessels, nerves, lymphoid reticular tissue, and embryonic remnant tissue are all Different types of tumors can occur. Many of these tumors had no obvious clinical manifestations in the early stage, and they were easily confused with celiac tumors, which caused certain difficulties in clinical diagnosis. A total of 137 retroperitoneal tumors were treated and treated. A brief analysis of 29 cases misdiagnosed before surgery was done.
