Anatomic study of gastric vascularization and its relationship to cervical gastroplasty.
The aim of this study was to perform an anatomic study of the stomach and its vascularization, evaluating the frequency of communication between the right gastroepiploic artery (RGEA) and the left gastroepiploic artery (LGEA), as well as their relationship to the length of the stomach without extramural (direct) vascularization in cervical gastroplasty. Forty-two fresh human cadaveric specimens were studied, and the presence of communication between the RGEA and the LGEA was observed in 26 of the dissected stomachs (61.9%). When communication was present (group 1), to a total length of 49.60 cm of greater curvature length, it was verified that approximately 16.48 cm of this curvature lacked direct extramural vascularization (33.20%). When there was non-communication (group 2), to a greater curvature length of approximately 45.41 cm, it was found that 18.96 cm of this curvature (gastric fundus) lacked direct extramural vascular perfusion (41.76%). Results obtained in both groups were tested for statistically significant differences by the Pearson correlation test (P<0.05). A P value of 0.05 or less was considered statistically significant. It can be concluded that the presence of communication between the RGEA and the LGEA increases extramural vascularization in the great gastric curvature.
