目的:探究腹腔镜超声(1aprascopicultrasound,LUS)在经腹腹腔镜肾部分切除术中的应用价值。方法:我院于2010年1～6月对5例肾肿瘤患者实施LUS辅助的经腹腹腔镜肾部分切除术。术中使用LUS对肿物部位、边界、大小进行实时观测,对切缘进行检测,并评估患者手术时问、术中出血量、术后病理切缘情况等指标。结果:入组患者平均年龄49.2岁(26～67岁),肿物直径平均2.1 cm(1.5～2.5 cm),手术时间平均106.8min(98～11 4 min),出血量平均70 ml(50～100ml)。手术进展顺利.所有患者术后病理检查证实切缘均阴性。手术时间、出血量较常规手术无明显差异。结论:采用LUS术中定位对肾实质内部肿瘤及小肿瘤具有良好的动态监测作用,不但可以防止过度切除正常的肾组织,还可有效地降低切缘阳性率。此项技术值得在临床上推广使用。
Objective: To investigate the value of laparoscopic ultrasonography (LAP) in laparoscopic partial nephrectomy. Methods: From January to June 2010, 5 cases of renal tumor patients underwent LUS - assisted transabdominal laparoscopic partial nephrectomy. Intraoperative use of LUS on the tumor site, boundary, size real-time observation of the cut edge detection, and evaluation of patients with surgery, intraoperative bleeding, postoperative pathological margins and other indicators. Results: The mean age of patients was 49.2 years (26-67 years). The average diameter of tumor was 2.1 cm (1.5-2.5 cm). The mean operative time was 106.8 minutes (98-114 minutes) and the average amount of bleeding was 70 ml 100ml). The operation went well. All patients had negative margins after surgery. Surgery time, blood loss than the conventional surgery no significant difference. Conclusion: LUS intraoperative localization of renal parenchymal tumors and small tumors have a good dynamic monitoring, not only can prevent excessive removal of normal renal tissue, but also effectively reduce the positive rate of the margin. This technology is worth promoting in clinic.
