The result showed that u rectum high and middle accounted for 35.3%, papules accounted for the highest rate 61.8%. Middle thickness the tumor of the tumor is 12.21 ± 4.93 mm (27mm- 5mm). There are 20.6% of cases where the tumor has anal sphincter invasion and 29.4% of cases with regional nodal tumors, tumors in the T3 stage is highest rate of 58.9%, lymph nodes of ≥ 5mm appear. over 29.4% of cases and was diagnosed with N1 stage. The correct diagnostic capacity for T-stages of endoscopic ultrasound versus post operative anapathology results: 82.4%. Sensitivity, specificity, accuracy for T1: 75%, 100%, 97.1%, T2: 63.6%, 95.6%, 85.3%. Stage T3 were 94.4%, 81.3%, 88.2%. Possible diagnostic accuracy for N-stages of endoscopic ultrasound versus postoperative anapathology 85.3%. Nodal sizes greater than 5 mm were 85.7%, 85.2%, 85.3% for sensitivity, specificity and accuracy in diagnostic nodal metastases.
