Seventy-three cases with superficial metastases of the dermal-hypodermal (59) layers, of the muscles (11) and of other target organs (3) were included in the study.Although non-glandular superficial metastases are a relatively rare occurrence, diagnostic imaging techniques are indicated for evaluating their extent and anatomical connections. Secondary neoplasms were studied using the imaging techniques of sono-graphy, computed tomography and xeroradiography.The diagnostic reliability of these three techniques was evaluated, taking into account their ability to determine the extent of metastases and of assessing malignancy.Sonography is considered as a satisfactory screening technique, but CT is an even better tool for evaluating the extent and anatomical connections of such lesions. Xeroradiography has been made obsolete by the introduction of the other two techniques.展开更多

Then group A took lansoprazole combined with tepreton for 5 wk, group B took lansoprazole and group C took tepreton for 5 wk. Endoscopy and EUS were performed before and 6 wk after medication. RESULTS: There was no significant difference in cumulative healing rate to S stage between the groups (89%, 82%vs83%,P＞0.05). The rate of white scar formation was significantly higher in group A than in groups B and C (67%, 36%, 50%, P＜0.05). The average contraction rates of the width of ulcer crater, length of disrupted muscularis propria layer and hypoechoic area were higher in groupA than in groups B and C (0.792±0.090, 0.660±0.105 vs0.668±0.143, P＜0.05). The hypoechoic area disappeared in four cases of group A, one of group B and two of group C. The percentage of hypoechoic area disappearance was higher in group A than in the other two groups (44%, 9%vs 17%, P＜0.05). Gastric ulcer healing was better ingroup A.CONCLUSION: The combined administration of proton pump inhibitors and mucosal protective agent can improve gastric ulcer healing.展开更多
