[Re-operation of 136 recurrent cases of colorectal cancer]

We analyed 136 recurrent colorectal cancer cases their recurrence, residual cancer foci, extraintestinal infiltration, and inappropriate pelvic resection in patients receiving mile's procedure. The authors suggest that distal safe margin of the colon should at least be more than 3 cm and thorough dissection of the proximal third grade lymphonodes at the upper root of the mesentery and the lateral lymphonodes. For these 136 recurrent cases, after preoperative comprehensive procedure including intraarterial chemoembolization, radiation adjuvant immunotherapy, the resection rate of the recurrent mass was 84.5%. The five year survival rate of palliative resection was 40% as compared with 44.8% in radical resection.
