目的探讨经腹膜后途径行腹腔镜手术治疗肾上腺肿瘤的临床疗效。方法回顾性分析我院自2007年3月~2014年6月采用后腹腔途径行腹腔镜肾上腺肿瘤切除术75例患者的临床资料及随访结果，其中肾上腺皮质醇腺瘤33例，醛固酮腺瘤26例，嗜铬细胞瘤12例，髓样脂肪瘤4例。结果75例手术均获得成功，无中转开放手术。肿瘤直径1.5~8.6 cm，平均直径2.8 cm；手术时间40~160 min，平均手术时间75 min；术中出血量20~110 mL，平均出血量41.5 mL；术后住院时间3~8 d，平均住院时间5.6 d。术后随访3~24个月，未见肿瘤复发。结论后腹腔镜治疗肾上腺肿瘤安全可行。具有创伤小、安全可靠、术后恢复快等特点，可作为治疗肾上腺肿瘤的一种首选手术方式。“,”Objective To discuss the clinical ef icacy of retroperitoneoscopic adrenalectomy of adrenal tumors.Methods Between March 2007 and June 2014,The 75 cases of adrenal tumors who underwent Retroperitoneal adrenalectomy.The clinical data of 75 patients were retrospectively analyzed.Results The operation was performed successful in al cases,without conversion to open surgery.The tumor size ranged from 1.5~8.6 cm(mean 2.8 cm).The operative time was 40~160 min(mean 75 min),and the blood loss was 20~110 mL(mean 41.5 mL).The postoperative hospital stay was 3~8 days(mean 5.6 d).The patients were fol owed up for 3~24 months.No recur ent tumor was found.Conclusion It was ef ective and safe by retroperitoneal laparoscopic adrenalectomy for adrenal tumors,which is safe,reliable,and less invasive,wil become the first choice for the treatment of adrenal tumors.
