The purpose of this paper is to evaluate the effectiveness of a new technique of hydrodissection for peritoneal structures displacement during preoperative localization markers placement. We retrospectively reviewed two cases of percutaneous fiducial marker placement prior rescue retroperitoneal lymphadenectomy. In both cases pressurized 5% dextrose in water (D5W) was used to hydrodissect the peritoneal space and securely reach the lymph nodes. Two patients were submitted to water jet technique for transperitoneal trespassing to reach the retroperitoneum. The volume of fluid used to navigate was 125-200 mL and the mean time to cross the peritoneum was 6 min 47 s (ranging from 3″26' to 10″24'). In conclusion, Bowel and small vessels displacement using pressurized D5W is a safe method to reach retroperitoneal space during percutaneous procedures.
本文旨在评估一种新的水分离技术在术前定位标记放置时对腹膜结构移位的效果。我们回顾性分析了两例经皮 fiducial 标记放置以挽救性腹膜后淋巴结清扫术的病例。在这两种情况下，都使用加压 5%葡萄糖水（D5W）来对腹膜腔进行水分离，以安全地到达淋巴结。两名患者均采用水流喷射技术经腹腔进入腹膜后间隙。导航时使用的液体量为 125-200ml，穿过腹膜的平均时间为 6 分 47 秒（范围为 3″26' 至 10″24'）。总之，使用加压 D5W 来移动肠管和小血管是一种在经皮操作中到达腹膜后间隙的安全方法。
