目的探讨原发性骶前肿瘤的诊断与治疗方法。方法回顾性分析1979~2001年间收治的12例原发性骶前肿瘤患者的临床资料。结果直肠指诊、B超、CT检查阳性者分别为10/12、 12/12及6/6； 肿瘤完全切除者9例，部分切除者2例，肿瘤未能切除仅行隐性乙状结肠造口术1例。经病理组织学检查，12例中畸胎瘤4例，上皮样囊肿5例，恶性淋巴瘤1例，神经纤维瘤1例，神经纤维肉瘤1例； 8例术后平均随访14个月，治愈6例，好转2例,无手术死亡。结论原发性骶前肿瘤临床表现不典型，直肠指诊、B超及CT检查有助于诊断； 完全切除是治疗原发性骶前肿瘤的主要措施。
Three types of intestinal loops were used to reestablish the internal drainage of bile in 17 cases. The leeway derived from the peristaltic cycle of the intestinal loop for gastrointestinal reflux pressure, the cholangeitis after operation from reflux following choladocho-intestinal anastomosis could be avoided, and, naturally it had changed the traditional method of purèly blockade of the reflux, thus the result from treatment was far more satisfactory.
