Unlabelled:
In the present study, we demonstrated a surgical submucosal resection (SSR) with an early stage gastric cancer for 212 patients. We assessed the results of SSR in 212 patients based on the outcome of surgery, recurrent cases and prognoses.
Result:
The mean operation time was 93 +/- 36 minutes, bleeding volume was 34.6 +/- 12.0 mL, and postoperative hospitalization in days was 11 +/- 4 days. Pathological examination revealed a tumor invasion of the mucosal layer in 155 cases, submucosal layer in 55 cases, and proper muscle in 2 cases. There were 14 cases (6.6%) of incomplete resection. We performed a curative resection for 6 cases and a frequent follow-up for 7 cases of incomplete resection. There was one gastric cancer death case in incomplete resection. There were no recurrent cases in complete resection. However, we found 3 missing diagnosis cases of synchronous multiple gastric cancer and 10 metachronous multiple gastric cancer cases.
Conclusion:
SSR is a useful option of minimally invasive surgery for an early stage gastric cancer.
