Objectives: To assess the clinical outcomes of laparoscopy for right colon cancer. Subject and method: The database was created by retrospectively reviewing hospital of the patients who underwent laparoscopic right hemicolectomy in 108 Military Central Hospital (from April 2015 to June 2018). Results: Tumor site often occurred at ascending colon and hepatic flexure (66.2%). Patients commonly were operated at stages I - II based on phathology (70.3%). The median size of tumor was 4.8 ± 1.8 cm. Lymph node harvest was 19.7 ± 7.1. The rate of positive lymph nodes was 28.4%. The average of operation time was 105.7 ± 30.5 minutes. The mean time of hospital stay was 8.7 ± 2 days. Two patients (2.8%) were converted to open surgery. The rate of postoperative complication was 9.7%. There was one case of anastomotic leakage, three cases with surgical site infection and one case of postoperative mortality. The three-year overall survival rate of all stages was 91.9%. The 3-year overall survival rates according to stages were 100% in stage I, 90.5% in stage II, and 88.6% in stage III. Conclusion: Laparoscopic complete mesocolic excision in right colon cancer treatment is technically feasible, safe and with acceptable complication rate. * Keywords: Right colonic cancer; Complete mesocolic excision; Laparoscopy; Oncologic outcome. INTRODUCTION At the end of the 19th century, Emil Theodor Kocher was the first to theorize oncologic resections based on removal of the involved organ along with its lymphatic drainage; this concept was shortly after substantiated by Miles et al and Jemison et al for rectal and colonic cancer respectively in .
