【摘要】 目的 :比较内镜超声 (EUS)和手术时触摸法对判断胃癌浸润深度及胃周淋巴结转移的准确性。方法 :73例经病理证实的胃癌病例 ,于术前接受EUS检查并在术时按Rhode原则进行评估 ,其结果与术后组织病理分期学相比较。结果 :在判断胃癌浸润深度 (T)上 ,EUS的准确性为 80 .8% (5 9/ 73) ,手术时评估的准确性为 5 8.9% (4 3/ 73)。在判断淋巴结转移 (N)上 ,前者的准确性为 6 0 .3% ,后者为 6 5 .8% ;但在 2 6例N0病例中 ,EUS分期的准确性为92 .3%而手术时评估的准确性仅为 5 7.7%。结论 :EUS判断胃癌的T及N0 ,较术中临床评估更为准确更多还原

【Abstract】 Objective: To compare the relative accuracy of endoscopic ultrasonography (EUS)and intra-operative clinical judgement in evaluating the depth of invasion(T)and extension of lymph node involvement(N)in patients with gastric cancer. Methods: From January through December 2000, 73 consecutive cases were studied by pre-operative EUS and intra-operative assessment for T and N. Results: For T, the assessment was made correctly by EUS in 59 patients(80.8%), and by clinical judgement alone in 43 patients(58.9%). For the assessment of N, EUS was accurate in 44 patients(60.3%), and linical judgement was correct in 48 cases(65.8%); however, in 26 patients proved pathologically to have no lymph node in volvement(N0), 24(92.3%) were correctly assessed by EUS and 15(57.7%) by clinical evaluation only. Conclusions: EUS is more accurate in assessing T and N0 of gastric cancer.更多还原
