Abstract

Most gastric malignancies are advanced at the time of detection, so accurate diagnosis and staging are important for treatment planning and evalution of the prognosis. CT is one of the most simple, rapid, non-invasivemethod of accurate diagnosis and staging of gastric malignancy. Authors analysed significance of preoperative CTstaging in 38 cases of pathologically confirmed gastric malignancies and the CT staging is compared with that of20 cases who underwent surgery. The results were as follows: 1. In a total of 18 cases who underwent surgery,resectability was 77.8% and false negative was 38.9%. 2. Causes of false negative interpretation are microinvasionto adjacent organs or metastatic micronodules, hidden regional lymphnode metastasis, misinterpretation to reactive hyperplasia of enlarged lymphnodes and indistint fat plane owing to severe emaciation. 3. Even a small localizedmass without gastric wall thickening, there was extensive distant metastases, so accurate preoperative CT stagingwould prevent unnecessary surgical exploration and will result in less complication, decreased mortality and expenses and allow more accurate treatment planning.
