目的探讨经腹超声在胃窦癌术前分期中的应用价值。方法对49例胃窦癌患者进行术前超声检查,并与术后病理进行对照。结果超声诊断T1、T2、T3和T4的符合率分别为40.0%、66.6%、75.0%和86.6%,总符合率73.4%。过深判断率12.2%(6/49),过浅判断率14.2%(7/49)。超声对腹腔淋巴结转移诊断的灵敏度为84.2%(16/19),特异度为56.6%(17/30),阳性符合率为55.1%,阴性符合率为85%,总符合率为73.0%。肝脏转移5例,卵巢转移1例,M0、M1符合率均为100%。结论经腹超声为胃窦癌术前分期提供了重要依据,对临床选择治疗方案有重要价值。
Objective To investigate the value of transabdominal sonography in the preoperative staging of gastric cancer. Methods 49 cases of gastric cancer patients underwent preoperative ultrasonography, and compared with postoperative pathology. Results The coincidence rates of T1, T2, T3 and T4 in ultrasound diagnosis were 40.0%, 66.6%, 75.0% and 86.6% respectively, with a total coincidence rate of 73.4%. Too deep judgment rate of 12.2% (6/49), too shallow judgment rate of 14.2% (7/49). The sensitivity, specificity and specificity of ultrasound in the diagnosis of peritoneal lymph node metastasis were 84.2% (16/19) and 56.6% (17/30) respectively. The positive coincidence rate was 55.1%, the negative coincidence rate was 85% and the total coincidence rate was 73.0%. Liver metastasis in 5 cases, ovarian metastasis in 1 case, M0, M1 coincidence rate was 100%. Conclusion Transabdominal ultrasonography provides an important basis for the preoperative staging of gastric cancer and is of great value to the clinical choice of treatment.
