A review was made of 128 patients who had obstructing cancer of the colon and rectum. About one-third of the patients had metastatic disease at the time of presentation. Primary resection carried an initial higher mortality rate than staged resection, but at one year and three years, no statistical difference can be found between the two procedures. There are high morbidity and mortality rates with all forms of treatment. A controlled comparative trial of primary and staged resection is recommended in the treatment of obstructing cancer of the colon and rectum.
对128例患有结肠和直肠癌梗阻的患者进行了回顾性研究。约三分之一的患者在就诊时已有转移性疾病。一期切除的初始死亡率高于分期切除，但在一年和三年时，两种手术方式之间未发现统计学差异。所有治疗方式都有较高的发病率和死亡率。建议对结肠和直肠癌梗阻的治疗进行一期切除与分期切除的对照比较试验。
