摘要
目的对比CT及腹腔镜联合CT在潜在可切除的胃癌术前分期中的准确性。方法数字随机入组194例胃癌患者。进行CT序贯腹腔镜评估，与术后病理比较。结果CT对胃癌T分期准确率为72．2％，增加腹腔镜后对T分期准确率为89．6％，差异有统计学意义（x2=7．844，P=0．005）；CT对N分期准确率为55．6％，增加腹腔镜后准确率为70．1％，差异有统计学意义（x2=4．329，P=0．037）。CT对M分期的准确率为90．7％，增加腹腔镜后准确率为97．9％，其差异亦有统计学意义（x2=4．722，P=0．030）。腹腔镜检查出14例腹膜种植转移。结论CT评价胃癌TNM分期的准确性有限，腹腔镜可以很大程度上提高其准确性，其主要体现在可以更准确的评估腹膜分期。
Objective To compare the accuracy of computer tomography （CT） plus diagnostic laparoscopy in preoperative staging of potentially resectable gastric cancer. Methods A total of 194 gastric cancer patients underwent combined CT and laparoscopic staging. Then the results were compared with those of pathologic TNM staging. Results Comparing with pathologic TNM stage, the T staging accuracy of CT was lower than that of laparoscopy （72. 7% vs 89.6%, X2 =7. 844, P =0. 005）, the N staging accuracies of CT and laparoscopy were 55.6% and 70. 1% （X2 = 4. 329, P = 0. 037 ） and the M staging accuracies 90. 7% and 97. 9% respectively （X2 = 4. 722, P = 0. 030）. The diagnostic laparoscopy uncovered 14 patients with peritoneal metastases. Conclusion The value of CT is limited in preoperative staging of gastric cancer. However its accuracy may be enhanced by laparoscopy through detecting more peritoneal metastasis.
