目前,早中期的结直肠癌患者在手术以后生存率较以前有了明显提高,大部分都达到了根治的目的,出现复发转移的较少。但是有的患者虽然肿瘤已经摘除,手术后却会出现排便次数增多,甚至不能自已控制大便,或者腹泻久治不愈等情况,严重影响了患者的生活质量。这究竟是什么原因引起的呢,遇到这种情况又该怎么办呢? At present, the survival rate of patients with colorectal cancer in the early and mid-term after surgery has been significantly improved than before, most of them have reached the goal of radical treatment, and there are fewer recurrences and metastases. However, in some patients, although the tumor has been removed, there will be an increase in the frequency of defecation after surgery, and it may not even be possible to control the stool, or if the diarrhea becomes permanently unhealed, which seriously affects the quality of life of the patient. What is the cause of this? What should we do in this situation?
