No Touch

Several studies have evaluated the no touch technique in colon cancer surgery. This requires ligation of the lymphovascular supply prior to mobilization of the colon and mass. These early studies showed a survival of 58% compared to 28% for no touch and conventional surgery respectively. More recent studies of the presence of tumor cells in the portal vein during and following surgery found that 73% of patients in the conventional group had evidence of tumor showering verses 14% in the no touch groups.
