Fujihara et al. Journal of Medical Case Reports 2012, 6:268 http://www.jmedicalcasereports.com/content/6/1/268 Page 2 of 4 Figure 1 Oozing bleeding was observed from the gastric cancer lesion after argon plasma coagulation. Figure 3 The following day, endoscopy revealed multiple lesions in the stomach. Bleeding of this polyp lesion persisted, and we did not determine whether it was a benign or a malignant tumor (in particular, hyperplastic poly or early gastric cancer). We considered that the bleeding point was not only on the sur- face of this polyp, but also within the deep mucosal layer. We decided to perform EMR to detect the deep vessels. Immediately after injecting a 0.4% sodium hyaluronate solution, EMR was performed (Figure 2a). After EMR, exposed vessels were detected at the base of the mucosal resection site, with spurting bleeding (Figure 2b). Coagulation of the bleeding vessels using an ERBE VIOW 200 generator (ERBE Elektromedizin, Tübingen, Germany) and hemostatic forceps allowed us to successfully complete the hemostatic procedure (Figure 2c). The bleeding stopped within two days. Our patient’s hemoglobin level subsequently stabilized at Figure 2 Endoscopic views before and after endoscopic mucosal resection.

(b) After endoscopic mucosal resection, exposed vessels were seen at the base of the mucosal resection site with spurting bleeding. (c) Endoscopic hemostasis was achieved using hemostatic forceps.
