| 摘 要： | 目的比较开腹和超声引导下深植入法和浅植入法建立兔肝VX2肿瘤模型的成功率和异位种植率。方法选取80只新西兰白兔,按植入组织块或其悬液及穿刺深、浅分为4组,超声引导下将VX2肿瘤组织块或其悬液穿刺接种于兔左肝内（浅≤20mm,深〉20mm）,接种后第1、2、3周行超声检查。第3周检查后处死实验兔,行原位、异位肿瘤肉眼及病理检查。结果开腹及超声引导下运用深植入法及浅植入法造模,成模率均为100%。开腹组及超声组织块组肿瘤体积明显大于组织块悬液组。组织块深植入法,开腹组及超声组无异位种植。组织块浅植入法,超声组1例腹腔种植,开腹组未见腹腔种植。组织块悬液深植入法,开腹组无腹腔种植,超声组2例腹腔种植。组织块悬液浅植入法,开腹组2例腹腔种植;超声组5例腹腔种植,其中1例同时腹腔和腹壁种植。结论超声引导下穿刺组织块及组织块悬液接种制作兔肝VX2瘤模型方法简单,创伤小,成功率高。组织块穿刺植入法优于组织块悬液穿刺植入法,深植入法优于浅植入法。
