Clinical and conventional endoscopic studies of gastric ulcer on the evaluation of the depth using endoscopic ultrasonography endoscopic findings of the different depth and its course



Clinical and conventional endoscopic studies of gastric ulcer on the evaluation of the depth using endoscopic ultrasonography endoscopic findings of the different depth and its course



Gastroenterological Endoscopy 34(4): 800-811



We studied on clinical evaluation and characteristic endoscopic pictures of 79 followed up gastric ulcers. Most of ulcers located at gastric angulus were identifed as UL-IV ulcers, but UL-IV ulcers at gastric body were only a half of cases. Based on the healing time, UL-III ulcers and UL-IV ulcers at gastric body without distinction of location were intractable. On the other hand, UL-II ulcers were tractable and UL-IV ulcers showed intractable ulcer pattern, but UL-II ulcers showed tractable ulcer pattern by conventional endoscopic pictures. UL-III ulcers showed the mixed characteristics of both UL-IV and UL-II ulcers. A half of cases with UL-IV ulcers relapsed for 12 months, but UL-II ulcers relapsed no case and UL-III relapsed a few cases. We followed up scar lesion endoscopically. The shallower depth of ulcer, improved disappeared earlier the ulcerative changes. In order to estimate characteristics of ulcer relapse of UL-IV, we compared endoscopic pictures. The relapse of ulcers showed low frequency, when the scar lesion changed to white scar. Based on these findings, we described the ulcer treatment in reference to depth of ulcer.
