AUSTRALASIAN MULTICENTRED PROSPECTIVE RANDOMISED STUDY OF LAPAROSCOPIC VS CONVENTIONAL SURGICAL TREATMENT OF COLON CA

结肠癌是西方社会最常见的实体瘤之一。通常的初始治疗是通过沿腹壁中线切开的手术切除癌症。在过去的10年里，微创技术改变了许多外科手术的方法。一个很好的例子是切除胆囊的手术。这是现在例行使用腹腔镜（望远镜），这是引入在脐。然后，使用视频屏幕上的胆囊图像来引导器械在不对腹壁进行大切口的情况下切除胆囊。这就是所谓的腹腔镜胆囊切除术。腹腔镜辅助方法切除结肠癌的安全性尚未确定。这项研究将比较通过剖腹手术（在腹壁中线切开）或腹腔镜辅助方法（望远镜）切除结肠癌的长期和短期结果。

Colon cancer is one of the most common solid tumours in western society. The usual initial treatment is excision of the cancer by an operation done through a cut down the midline of the abdominal wall. Over the past 10 years, minimally invasive technology has changed the approach to many surgical operations. A good example of this is an operation to remove the gall bladder. This is now routinely done using a laparoscope (telescope) which is introduced at the umbilicus. An image on a video screen of the gall bladder is then used to guide instruments to remove the gall bladder without making a large incision in the abdominal wall. This is called a laparoscopic cholecystectomy. The safety of a laparoscopic assisted approach in the removal of colon cancer is yet to be determined. This study will compare the long term and short term outcomes of people who have colon cancers removed either by a laparotomy (a cut in the midline of the abdominal wall) or by a laparoscopic assisted approach (telescope).
