METHODS Clinical data of 18 patients with INP, who were admitted to the PLA General Hospital in 2017, were retrospectively analyzed. Two-dimensional images of computed tomography were converted into 3 D images based on 3 D visualization technology. The size, number, shape and position of lesions and their relationship with major abdominal vasculature were well displayed. Also, percutaneous catheter drainage(PCD) number and puncture paths were designed through virtual surgery(percutaneous nephroscopic necrosectomy) based on the principle of maximum removal of infected necrosis conveniently.RESULTS Abdominal 3 D visualization images of all the patients were well reconstructed, and the optimal PCD puncture paths were well designed. Infected necrosis was conveniently removed in abundance using a nephroscope during the following surgery, and the median operation time was 102(102 ± 20.7) min. Only 1 patient underwent endoscopic necrosectomy because of residual necrosis. CONCLUSION The 3 D visualization technology could optimize the PCD puncture paths, improving the drainage effect in patients with INP. Moreover, it significantly increased the efficiency of necrosectomy through the rigid nephroscope. As a result, it decreased operation times and improved the prognosis.展开更多

文摘目的 探讨经皮肾镜微创治疗重症急性胰腺炎（SAP）开腹术后残余感染灶的方法及疗效.方法 回顾性分析自2008年6月至2014年12月解放军总医院采用经皮肾镜微创坏死组织清除术治疗15例SAP开腹治疗术后残余感染患者的资料.男性8例,女性7例,年龄22 - 71岁,平均42岁.患者发病至开腹手术时间：1 -7 d 12例,15 -21 d 1例,22-28 d 1例,127 d 1例.本组患者均采用先行CT引导下经皮穿刺置管引流,再行经皮肾镜坏死组织清除术,术后持续腹腔内冲洗的治疗方法.结果 15例患者中,11例接受肾镜治疗1次,2例2次,1例3次,1例4次;术后平均住院时间66.2 d（10-223 d）;术后1例患者出现结肠瘘予以双套管冲洗治愈;1例出现腹腔内出血行动脉造影未见明显出血,后行剖腹探查止血;1例出现胰腺假性囊肿予以置管引流;1例出现严重的肺部感染.3例患者死亡,死因均为多器官功能衰竭.结论 经皮肾镜胰周坏死织清除术创伤小,避免再次开腹分离粘连、寻找坏死灶所带来的并发症,可能是治疗SAP术后残余感染的理想方法.
