“…Therefore, expansion of the indication of proximal gastrectomy to advanced upper-third gastric cancer has not been generally accepted [10]. Anatomically, the lesser curvature of the stomach is fed by two arteries: the left gastric artery (LGA) and the right gastric artery (RGA) [11,12]. The no.…”

Background Proximal gastrectomy has been introduced for early gastric cancer located in the upper third of the stomach, but expansion of its indication to advanced tumors has not been generally accepted in terms of lesser curvature lymph node dissection. Methods We reviewed the medical records of 385 patients with tumors in the upper third of the stomach, and the incidence of metastasis and the therapeutic index related to the proximal (no. 3a) and distal (no. 3b) lymph nodes of the lesser curvature were analyzed and compared with those of tumors in the middle third (n = 1093) and lower third (n = 922) of the stomach. Results The no. 3a rate of metastasis from advanced tumors in the upper third of the stomach was significantly higher than that from tumors in the middle third or lower third of the stomach. The no. 3b metastasis rate did not show any significant differences between the three locations, but the therapeutic index of no. 3b lymph nodes in the upper third of the stomach (1.7) was far lower than that in the middle third (7.1) or lower third (7.0). Further, the rate of metastasis from tumors with the distal border ending in the upper third of the stomach (2.2 %) was significantly (P \ 0.0001) lower than that from tumors located in the upper third of the stomach but extending to the middle third (19.6 %), as well as from tumors located in middle third (17.1 %) or lower third (19.6 %), with the therapeutic index being only 1.1. The four no.-3b-positive tumors all measured more than 40 mm, and included one T3 tumor and three T4 tumors. Conclusion Proximal gastrectomy with exclusion of no. 3b lymphadenectomy could be indicated for at least T2 tumors measuring less than 40 mm localized in the upper third of the stomach.

Summary: Background: The gastroepiploic artery (GEA) has been described in various ways by anatomical texts and surgical manuals. Currently, there are no studies that have investigated the thickness and length of GEA using gross anatomical methods. In the present study, we measured the length, circumference, area, and major axis of GEA, and quantitatively evaluated the differences between right and left GEA (RGEA and LGEA), using gross anatomical and morphometric methods for the first time. Materials and Method: Seventeen cadavers were selected. The median age of the cadavers was 82 years. We observed and evaluated GEA with naked eyes, as well as under a stereoscopic microscope. Results: RGEA was significantly longer than LGEA (p < 0.0001). The mean length of RGEA and LGEA were 26.51 ± 5.15cm and 14.05 ± 3.12cm, respectively. The mean area of RGEA, LGEA, and the anastomotic point were 3.31 ± 1.71 mm 2 , 1.33 ± 1.01 mm 2 , and 0.51 ± 0.28 mm 2 respectively. Conclusion: RGEA was significantly longer and thicker than LGEA. The results also showed that in almost all of the cases RGEA and LGEA anastomosed with each other and grew thinner as they approached the middle of the greater curvature of the stomach.

“…Although Adachi described the branching pattern of the celiac arterial distribution [3], there are no gross anatomical studies about GEA, which is the peripheral artery of the celiac artery. All currently available information on this artery is from biological or surgical specimen evaluations using angiography and 3-dimensional computed tomography [4][5][6][7][8]. Furthermore, there is no unified view on the anastomosis patterns of GEA.…”

Summary: Objective: Knowledge of the anatomy of the stomach and its surrounding structures is essential for lymph node dissection. This is the first gross anatomical investigation of anastomosis variations in the gastroepiploic arteries (GEA). The aim of this study is to examine the anastomosis pattern of the right and left GEA (RGEA and LGEA, respectively). Methods: Seventeen cadavers were dissected, and the anastomotic patterns of RGEA and LGEA were observed macroscopically. Results: The anastomotic patterns were classified into two groups. Type 1 had direct anastomosis (n = 16; 94.1%), whereas Type 2 had no anastomosis (n = 1; 5.9%). Formation of an arterial arch along the greater curvature was observed in twelve cases (70.6%), whereas four cases (23.5%) exhibited mesh-like anastomosis or narrow anastomotic branches. Conclusions: Direct anastomoses were observed in almost all the cases. These results are significant, and may be useful in the classification of lymph nodes or speculation of cancer metastases.
