CT evaluation of 150 cases of gastric carcinoma

While double contrast x-ray examination and endoscopy are highly accurate in evaluating intraluminal lesion of stomach, they do not offer proper information regarding gastric wall and extragastric lesion. CT is very much valuable and vital in evaluating the above structures. Information obtained through CT is valuable in planning of treatment, surgical resectability and prognosis. Authors analysed 150 cases of gastric carcinoma diagnosed at this hospital through CT scan during period between January 1986 and October 1988. 50 cases received surgery. The following results were obtained. 1. Among 50 cases who received surgery, CT staging according to modified Moss's CT classification is accurate compared with surgery and pathology in 96 percent. 2. Adopting new criteria in evaluating perigastric lymph node metastasis, 94%'s accuracy is obtained. 3. CT is poor in evaluating presence of asites, lesions of mesentery, omentum. Peritoneoscopy is suitable for this purpose. Combined CT examination and peritoneoscopy will render almost complete and accurate evaluation of extragastric lesion resulting from gastric carcinoma. 4. High quality CT machine, meticulous technic and high standard CT interpretation are vital in reaching accurate diagnosis
