Abstract
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%, χ² = 7.844, P = 0.005), the N staging accuracies of CT and laparoscopy were 55.6% and 70.1% (χ² = 4.329, P = 0.037) and the M staging accuracies 90.7% and 97.9% respectively (χ² = 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.
