The investigation has shown that on the lesser curvature in the area of the body and cardial part of the stomach there is a 2.3+/-0.3 cm section where there are no large branches of the left gastric artery and tributaries of the coronary vein. In the antral portion of the stomach such a section is not determined. Here there are terminal branches of the posterior descending and right gastric arteries. However, the diameter of these arteries when introduced into the gastric wall is rarely more than 1 mm. In addition, the arterial loops of the first and second order are formed on the anterior and posterior walls of the antral portion by the arteries of less diameter than in other parts of the stomach. In cases of the bleeding complicating the gastric ulcer it can be observed from any part of blood circulation, but the severity of bleeding is mainly dependent on the erosion of the arterial vessels. Hence, the site of the ulcer in the zone of the invasion of large arterial vessels into the gastric wall and their presence in the crater in the endoscopy picture should incline the surgeon to operative intervention.
调查显示，在胃体和贲门部小弯侧有一段2.3±0.3厘米的区域，此处无胃左动脉的大分支和冠状静脉的属支。在胃窦部未发现这样的区域。这里有后降动脉和胃右动脉的终末分支。然而，这些动脉进入胃壁时的直径很少超过1毫米。此外，胃窦部前壁和后壁由直径比胃其他部位小的动脉形成一级和二级动脉环。在胃溃疡并发出血的情况下，可在血液循环的任何部位观察到，但出血的严重程度主要取决于动脉血管的侵蚀。因此，在内镜图像中，溃疡位于大动脉血管侵入胃壁的区域以及溃疡灶内存在大动脉血管，这应促使外科医生进行手术干预。
