对比达芬奇机器人和开腹手术治疗原发性腹膜后肿瘤的临床疗效。

回顾性分析2015年3月至2018年6月在青岛大学附属医院接受手术治疗的57例原发性腹膜后肿瘤患者的临床资料，其中达芬奇机器人手术26例(达芬奇机器人手术组)，开腹手术31例(开腹手术组)，对比两组的手术时间、术中出血量、术后住院时间、住院费用、并发症情况。

达芬奇机器人手术组术中出血量(16.85±16.0)ml，明显少于开腹手术组(55.8±44.2)ml，差异有统计学意义(t＝4.564，P<0.000)；达芬奇机器人手术组术后住院时间(3.15±1.7)d，少于开腹手术组术后住院时间(4.61±1.9)d，差异有统计学意义(t＝3.027，P＝0.004)；但开腹手术组住院费用(33 825±8 432)元，显著低于达芬奇机器人手术组住院费用(53 712±6 424)元，差异有统计学意义(t＝9.858，P< 0.000)；达芬奇机器人手术组的手术时间(156.15±62.9)min、开腹手术的手术时间(144.39±41)min，差异无统计学意义(t＝0.818，P＝0.418)；两组并发症发生率分别为0.08%、0.15%，差异无统计学意义(χ²＝0.042，P＝0.837)。

虽然住院费用较高，达芬奇机器人治疗原发性腹膜后肿瘤仍有一定优势。

To compare the clinical outcomes between da Vinci robotic surgery and open surgery for primary retroperitoneal tumor.

This retrospective study recruited clinical data of 57 patients with primary retroperitoneal tumor who underwent surgery in Affiliated Hospital of Qingdao University from Mar.2015 and Jun. 2018, 26 cases performed da Vinci robotic surgery and 31 cases received open surgery.The operative time, blood loss, hospital stay, hospitalization expenses and complication were compared.

The blood loss in the da Vinci surgery were (16.85±16.0) ml, obviously less than that of open surgery (55.8±44.2) ml (t=4.564, P<0.000); and the hospital stay in da Vinci surgery were (3.15±1.7) days, less than that of open surgery (4.61±1.9) days (t=3.027, P=0.004), but the hospitalization expenses in the open surgery were (33 825±8 432) yuan, which were significantly lower than that of da Vinci surgery (53 712±6 424) yuan (t=9.858, P<0.000); the operation time of da Vinci operation was (156.15±62.9) min, and the operation time of open surgery was (144.39±41) min, there was no statistical difference (t=0.818, P=0.418). The incidence of complications rate in the two groups were 0.08% and 0.15%, respectively, and there were no statistical difference (χ²=0.042, P=0.837).

Although the hospitalization expenses are more expensive, da Vinci robot still has some advantages in the treatment of primary retroperitoneal tumor.
