该方案描述了结直肠癌肝转移的腹腔镜切除术与超声引导下的微波消融相结合。该技术可以安全、有效、准确地治疗难治性肝转移<3cm,减少术后并发症,加速患者术后康复。

手术切除联合微波消融为多发性结直肠癌肝转移提供了一种安全有效的方法,尤其是在残余肝容量不足的情况下。该技术简化了手术程序,降低了出血和胆汁渗漏等并发症的风险,缩短了手术时间,加速了术后恢复。除结直肠癌肝转移外,该方法还可应用于多发性原发性肝癌或其他继发性肝肿瘤。

建议在使用该技术之前,在腹腔镜超声的指导下,掌握肝脏超声的基本理论并练习门静脉穿刺。将 12 厘米的套管库插入肚脐和腹腔进行擦除。将五厘米的套管针放在剑突下方和右锁骨中线肋缘下方。

通过将海军套管针放入腹腔镜中检查腔和实质器官。使用超声波刀,分离附着在腹壁和肝膈肌上的圆形和扁平状韧带。静脉注射造影剂后,将腹腔镜探头放入腹腔。

然后通过将探针移动到组织上来检查肝脏。使用超声定位 S5 和 S7 肝段中的造影剂定义的转移性肿瘤。接下来,插入两个五厘米的套管针以帮助进行手术。

使用超声探头确认肿瘤的位置。使用超声手术刀去除连接组织。暴露第二节和第三节之间的肝椎弓根,并切断脐裂静脉的分支。

然后开始用超声手术刀解剖左外叶的薄壁组织。继续解剖整个叶。然后切断左外叶。

收集解剖的叶。然后通过去除周围的连接组织来分离肝脏。接下来,使用腹腔镜超声定位肿瘤边界并标记肝脏表面。

使用超声探头检测肝转移的位置,并标记距离肿瘤边缘小于一厘米的位置。通过经皮穿刺将微波消融针插入腹腔。在腹腔镜探针引导下将针头插入肿瘤中心并进行微波消融。

使用超声手术刀完全消融后取出针头,电凝肝实质切片。继续电凝,直到肿瘤组织被切除。收集纸巾并将其放入袋子中。

放置止血纱布。然后通过冲洗组织并去除止血纱布来清洁腹腔。松开脐裂静脉并清除组织碎片。

最后放置引流管。手术时间为 130 分钟。肝脏消融在低于 55 瓦的功率下成功持续 5 分钟,术中失血量低至 50 毫升。

未观察到术后并发症,导致患者在手术后 8 天出院。注射造影剂后,腹腔镜超声扫描整个肝脏非常重要。它可能显示术前影像学检查中难以发现的病变,例如 MR 或 CT。
