Laparoscopic complete mesocolic excision is a concept that using laparoscopic surgery technique to perform a resection for colon cancer. Besides, the segment of the colon containing the tumor, the resection area should include an intact mesocolon as an envelope to encase the possible route for metastasis. The routes include blood vessels, lymphatic drain and etc. Such hypothesis predicts better histopathological and higher oncological results which turns into better survival rate and better quality of life.

Primary Outcome Measures:
  • Histopathological Outcomes Obtained Through the Surgeries [ Time Frame: 14 days after the surgery ]
    number of lymph nodes retrieved

Secondary Outcome Measures:
  • Survival Rate [ Time Frame: 3 years after the surgery ]

Enrollment: 99
Study Start Date: June 2012
Study Completion Date: October 2015
Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: laparoscopic complete mesocolic excision
Randomized group of patients receiving laparoscopic colectomy with the concept of complete mesocolic excision
Procedure: laparoscopic complete mesocolic excision
laparoscopic complete mesocolic excision would be applied on randomized group of patients suffering colon cancer and possessing no marked surgical anti-indications. Lap.CME facilitaes medial approach to complete the procedure. CME and HMA are the two arms of the medial approach utilized.
Other Names:
  • laparoscopic CME
  • Complete Medial Approach (CMA)
  • Hybrid Medial Approach (HMA)
Active Comparator: D3 laparoscopic colectomy
Randomized group of patients receiving laparoscopic colectomy with D3-resection
Procedure: D3-laparoscopic colectomy
D3-laparoscopic colectomy would be applied on randomized group of patients suffering colon cancer and possessing no marked surgical anti-indications.
Other Name: D3 laparoscopic colectomy
