METHODS:A total of 1000-2000 mL of saline was instilled per rectum using a system for barium enemas,and then ultrasonography was conducted by a SSA-270A (Toshiba Co,Japan) sonolayer unit with a 3.75 MHz for 17 patients with colon cancer and 13 patients with rectal cancer before operation.After operation,T stage in HUS was compared with postoperative histological findings. RESULTS:Overall,the accuracy of T stage was 70%.It was 88% in colon cancer and 46% in rectal cancer.In evaluating nodal state,the accuracy of HUS was low in both colon (71%) and rectal cancers (46%) compared with conventional CT or MRI.The overall accuracy of N staging was 60%. CONCLUSION:HUS is valuable to evaluate the depth of invasion in colon cancer,but is less valuable in rectal cancer.Because HUS is low-cost,noninvasive,and readily available at any place,this technique seems to be useful to determine the preoperative staging in colon cancer,but not in rectal cancer.展开更多
