Objective To summarize the experience in diagnosis and treatment of primary retroperitoneal tumor (PRT). Methods Clinical data of 69 patients with PRT from June 1998 to June 2008 were analyzed retrospectively. Results Bellyache, abdominal distention, and abdominal mass were common symptoms in the patients with PRT. Ultrasound, CT, and MRI examination were effective. The major histopathological classification was soft tissue tumor, germinoma, lymphatic hematopoietic system tumors, and other rare tumors. Complete resection of tumors was performed in 42 cases, combined organs resection in 10 cases, partial resection of tumors in 11 cases, and only biopsy in 6 cases. There were 10 cases of intraoperative vessel and organ injury, which were treated by repair or vessels suturing and combined organ resection. Postoperative complications occurred in 8 cases, which were cured by conservative treatment. One patient died of hemorrhage acute stress ulcer combined multiple organ failure. The survival rates of 1, 3, and 5 years in patients underwent complete resection of tumors were 71%, 64%, and 46%, respectively. Of 11 patients underwent partial resection of tumors, 8 cases died within one year, and 3 cases died within 3 years after operation. All malignant tumor patients treated by biopsy died within one year after operation.Conclusion Synthetically using imaging examination may diagnose definitely, and to resect tumors as much as possible will improve patients’ survival.
目的探讨原发性腹膜后肿瘤行腹腔镜手术的安全性和疗效。 方法回顾性分析新疆医科大学第二附属医院普外科2008年4月至2013年4月期间行腹腔镜手术治疗的12例原发性腹膜后肿瘤患者的临床资料。 结果12例患者均行腹腔镜手术，其中1例中转开腹手术，其余行腹腔镜手术成功。平均手术时间190 min，术中平均出血300 mL，术后平均8.5 d出院。术后左下肢深静脉血栓形成1例，经保守治疗好转。围手术期无死亡患者。术后病理类型：良性肿瘤5例，其中神经鞘瘤1例，脂肪瘤1例，腹膜后囊肿2例，畸胎瘤1例；恶性肿瘤7例，其中纤维肉瘤2例，平滑肌肉瘤1例，恶性淋巴瘤2例，脂肪肉瘤2例。良性肿瘤平均直径8.1 cm，恶性肿瘤平均直径5.6 cm。随访7例恶性肿瘤患者，平均随访时间13个月，无复发及转移。 结论通过本组有限的病例资料初步得出，原发性腹膜后肿瘤的诊断主要依靠影像学检查。对于肿瘤直径≤10 cm的良性肿瘤或直径≤6 cm的恶性肿瘤且未侵犯主要血管者行腹腔镜手术治疗安全、可行。
