Mortality following elective colorectal cancer surgery range between 2.5-6% and increase for the elderly and frail patient regardless of T-stage. Around 80% of the patients who present with a colon cancer and is in a condition where surgery is possible will be offered resection of the tumor. A part of the colon is always removed together with the lymph nodes in order to ensure that cancer cells are not left behind. The risk of lymph node metastasis is dependent on several histopathological characteristics of the tumor. The overall risk of lymph node metastases is less than 20 % in patients with early colon cancer. This indicates that the majority of patients with early colon cancer have no benefit of additional resection besides local tumor excision. The alternative to resecting a larger part of the bowel is to make more focused surgery only resecting a small part of the bowel part through a combination of laparoscopic and endoscopic techniques. This new organ sparing approach is called Combined Endoscopic Laparoscopic Surgery (CELS). The investigators aimed to examinate the hypothesis that organ preserving approach (CELS) provides superior quality of recovery in elderly frail patients with small colon cancers when compared with standard surgery in RCT.
