目的 探讨小儿腹腔镜下腹膜后肿物切除术的安全性和有效性。方法 2009年8月~2016年5月对14例小儿腹膜后肿物采用腹腔镜手术切除,其中右上腹膜后肿物采用悬吊肝右叶暴露肿瘤的方法,用Hem-o-lok夹闭肿瘤动脉和静脉分支,断离血管后将肿物完整切除;左上腹膜后肿物,将结肠韧带游离,脾脏和胰腺掀起,暴露肿瘤,用Hem-o-lok夹闭肿瘤动脉和静脉分支后切除肿瘤。1例右侧髂血管表面肿瘤,将肿物与髂静脉分离后完整切除。1例左侧结肠旁沟内囊性肿物,沿边界将肿物完整切除。结果 12例成功完成腹腔镜腹膜后肿物切除术,2例中转开腹手术。手术时间60~230 min,平均126 min;术中出血量10~100 ml,平均41 ml,无输血者。术后住院时间1~7 d,平均4 d。术后病理：节细胞神经母细胞瘤5例,成熟性畸胎瘤3例,肾上腺囊肿2例,囊性淋巴管瘤1例,囊性肉芽肿1例,消化道畸形1例,节细胞胶质瘤1例。14例随访1~82个月（中位数32.5月）,未见复发。结论 腹腔镜腹膜后肿物切除术是治疗腹膜后肿瘤安全而有效的方法。

英文摘要：

Objective To investigate the safety and feasibil ity of laparoscopic resection for retroper itoneal tumors in children. Methods Fourteen children aged from 2 months to 14 years old with retroperitoneal tumors underwent laparoscopic resection between August 2009 and May 2016. The right liver lobe was suspended to expose the upper right retroperitoneal tumor, and the tumor was resected after Hem-o-lok ligation of the tumor5 s vessels. The colon, spleen and pancreas were dissected to expose the upper left retroperitoneal tumor, and the tumor was removed after ligation of the blood vessels. The lower right retroperitoneal tumor was on the surface of right iliac blood vessels, which was resected after dissection of the right iliac vein. The lower left retroperitoneal tumor was located in the left paracolic sulcus, and was removed after dissection of surrounding tissue. Results Twelve pa tien ts underwent the laparoscopic resection successfully and two patients were converted into open surgery. The time required for surgery was 60 - 230 min （mean, 126 min） , and the blood loss was 10-100 ml （mean, 41 ml） without necessity for blood transfusion. The hospital stay period after the operation was 1-7 days （ mean, 4 days ） . The postoperative pathological results included 5 cases of ganglioneuroblastoma, 3 cases of mature teratoma, 2 cases of adrenal cyst, 1 case of cystic lymphangioma, 1 case of cystic granuloma, 1 case of congenital malformation of digestive tract and 1 case of ganglioglioma. The patients survived with no evidence of recurrence during the follow-up period for 1-82 months （median, 32.5 months）. Conclusion Laparoscopic resection of retroper itoneal tumor for children is safe and effective.
