腹膜后肿瘤在临床上并非少见,手术切除仍是目前大多数腹膜后肿瘤主要的治疗方法。由于腹膜后间隙的解剖范围广、部位深,组织结构复杂,腹膜后肿瘤缺乏特异性临床表现,难以早期发现,确诊时肿瘤往往已较大。另外,由于肿瘤常累及腹膜后血管、神经及脏器,解剖关系复杂,致使手术难度 Retroperitoneal tumor is not uncommon in clinical practice, surgical resection is still the main treatment for most retroperitoneal tumors. Due to the wide range of dissection of retroperitoneal space, deep site, complex tissue structure, the lack of specific clinical manifestations of retroperitoneal tumors, early detection is difficult, the diagnosis of the tumor is often larger. In addition, as the tumor often affects the retroperitoneal blood vessels, nerves and organs, the anatomy of the complex, resulting in difficulty of surgery
