94 min) or perforation rate (4.2% vs. 5.1%). Sixteen SM1-EGC patients (22.2%) underwent surgical resection after ESD as an additional treatment, and lymph node metastasis was found in only 1 case. Additional surgical resection was performed for 57 patients (72.2%) of SM2-EGC patients, and lymph node metastasis selleckchem was observed in 8 of these patients. Of 33 patients who did not undergo additional

curative surgical resection, 2 patients with SM2-EGC had recurrence of lymph node metastases and underwent surgery, but no patient with SM1-EGC had lymph node metastases or local recurrence. Conclusion: ESD for SM1-EGC based on expanded criteria may be feasible, but additional long-term follow-up data are needed. Key Word(s): 1.

tract tumors can be seen in end-stage malignant disease, is clinically diagnosed during his lifetime was rare. Review the experience cases of metastatic gastric tumors, we report, including the endoscopic findings and therapeutic adaptation. Methods: We have experienced 17 cases (with28 lesions) of metastatic gastric tumor. 8 cases of female and 9 cases of male, 67 -year-old average age. Primary tumor were detected 7 cases of lung cancer, two cases of pancreatic cancer and bile duct cancer, one each in esophageal cancer, breast cancer, colonic cancer. Nine cases of digestive tract bleeding, abdominal pain, clinical symptoms that triggered the discovery was 8 cases is asymptomatic. At the first visit is the seven cases, the discovery period was 4–60 months after the primary tumor found in six cases other. Results: Gross morphology was submucosal tumor -like polypoid lesions with a central ulcer formation in 17 lesions, primary gastric cancer similar lesions in 6, and 2 lesions peptic ulcer similar. From the form, rather than transfer the serosal side invasion of intraperitoneal seeding, hematogenous metastases was suggested.
