In order to minimise relapses and functional problems after vagotomies, an anatomic study of the vagus nerve at the base of the esophagus and stomach was carried out. Fifty stomachs of adult black African corpses were collected, placed in a formaldehyde solution and then dissected. At the level of the esophageal hiatus, the trunks of the vagus nerve were found in 46% of the cases for the anterior vagus and 24% for the posterior. At the level of the abdominal esophagus there was a single anterior vagus in 68% of cases and single posterior vagus in 64% of cases. At the level of the greater curvature, a recurrent anterior branch was found. At the level of the lesser curvature, the main nerves had a plexiform appearance in 8% of cases for the anterior nerve and 6% of cases for the posterior nerve. The classical arrangement was found in 60% of cases for the main anterior nerve and 64% of the cases for the posterior nerve. At the level of the angulus, the classical crowsfeet was found in 20% of cases for the anterior vagus and in 32% of cases for the posterior vagus. The anterior vagus was plexiform in 54% of cases and 46% of cases for the posterior. This study confirms the extreme variability of the vagus in the stomach. A better knowledge of the variations should lead to more successful vagotomy regardless of its forms.
为了尽量减少迷走神经切断术后的复发和功能问题，对食管和胃底部的迷走神经进行了一项解剖学研究。收集了50具成年非洲黑人尸体的胃，置于甲醛溶液中，然后进行解剖。在食管裂孔水平，前迷走神经干在46%的病例中被发现，后迷走神经干在24%的病例中被发现。在腹段食管水平，68%的病例有单一的前迷走神经，64%的病例有单一的后迷走神经。在大弯侧水平，发现了一条返行的前支。在小弯侧水平，8%的病例中前神经呈丛状，6%的病例中后神经呈丛状。60%的病例中前主神经和64%的病例中后主神经呈经典排列。在角切迹水平，20%的病例中前迷走神经呈经典的爪形，32%的病例中后迷走神经呈经典的爪形。54%的病例中前迷走神经呈丛状，46%的病例中后迷走神经呈丛状。这项研究证实了胃内迷走神经的极端变异性。更好地了解这些变异应能使无论何种形式的迷走神经切断术都更成功。
