- How to Read a Study Record
- Compared with traditional open colectomy, laparoscopic surgery is associated with less pain, earlier recovery, and better cosmetic outcome, and its short- and long-term oncologic outcomes have been demonstrated.
- In experienced surgeons' hands, single incision laparoscopic surgery is increasingly performed for colorectal disease, and even for malignant lesion because of its reduced incision-associated morbidity and scarring.
- However, the safety and efficacy of single incision laparoscopic surgery for colorectal cancer has not yet been evaluated. Thus, the prospective randomized trial comparing single incision versus conventional laparoscopic surgery for colorectal cancer is needed.

- Early morbidity rate [ Time Frame: 30 days ]The early morbidity rate is defined as the event observed during operation and within 30 days after surgery,
- Operative outcomes [ Time Frame: intraoperative ]Operative time, estimated blood loss and incision length are recorded.
- Pathological outecomes [ Time Frame: 5 days ]Tumor size, length of proximal and distal margin and lymph nodes harvested are used to assess oncological resection.
- Postoperative recovery course [ Time Frame: 14 days ]Time to first ambulation, flatus, liquid diet, soft diet, and duration of hospital stay are used to assess the postoperative recoverty course.
- Pain score [ Time Frame: 14 days ]Postoperative pain is recorded using the visual analog scale (VAS) pain score tool on postoperative day 1, 2, 3 and the day of discharge.
- Cosmetic assessment [ Time Frame: 14 days ]Cosmetic assessment is perform using body image scale and cosmetic scale.
- 3-year disease free survival rate [ Time Frame: 36 months ]
- 5-year overall survival rate [ Time Frame: 60 months ]
- Inflammatory and immune response [ Time Frame: 7 days ]
