Experimental: Complete Mesocolic Excision
the group underwent laparoscopic right hemicolectomy with CME. In complete mesocolic excision group (CME), the dissecting extent includes the lymphatic and fat tissues surrounding the root of ascending mesocolon, which situated on the surface of superior mesenteric vein, and the root of right half of transverse mesocolon, which situated on the surface of pancreas neck.
the group underwent laparoscopic right hemicolectomy with CME. In CME group, in addition to D2 dissection, the whole mesocolon, from ascending colon to right half transverse colon, as well as the central lymph nodes should be entirely removed.
Intervention: Procedure: Complete mesocolic excision (CME)
Active Comparator: D3 lymph node dissection
the group underwent laparoscopic right hemicolectomy with D3 lymph node dissection. In D3 lymph node dissection group(D3), the lymph node dissection is based on ligating the supplying vessels close to the right-side of superior mesenteric vein and clean up the surrounding lymph node and adipose tissue. No.6 lymph node should be dissected in this group.
the group underwent laparoscopic right hemicolectomy with D3 lymph node dissection. In D3 group, the mesocolon should be removed and the dissection involves the paracolon and intermediate lymph nodes,including No.6 lymph node, which along the feeding vessels.
Intervention: Procedure: D3 radical operation
- Disease-free survival [ Time Frame: 3 years ]
- The rate of postoperative complications and mortality [ Time Frame: 30 days ]
- 3 years overall survival [ Time Frame: 3 years ]
- The rate of local and distant recurrence [ Time Frame: 3 years ]
- The accuracy of preoperative staging with CT [ Time Frame: 14 days ]
