不可手术和难以控制的直肠癌出血,给治疗带来困难。因肿瘤使血管固定而不能收缩,故局部电凝无效,结肠造口术亦无助于病人。唯一疗法是反复输血。 明矾是传统的收敛止血剂。Kenned等曾报道用明矾液冲洗一例难以控制的膀胱出血的患者。启示作 Inoperable and difficult-to-control hemorrhages in rectal cancer make it difficult to treat. Since the tumor is fixed by the tumor and cannot be contracted, local coagulation is not effective and the colostomy does not help the patient. The only therapy is repeated blood transfusions. Alum is a traditional astringent hemostatic agent. Kenned et al. have reported flushing an uncontrolled bladder hemorrhage with alum solution. Revelation
