近年来减重与代谢手术在中国得到快速发展。但由于肥胖患者手术操作空间小，脾胃韧带较短，部分脾上极动脉走行异常，在游离胃底体部过程中容易损伤脾上极动脉，一旦出血，止血时非常棘手。本文结合本中心临床经验重温胃底周围相关解剖，希望引起减重与代谢外科医生重视，以尽可能有效避免术中脾上极动脉的损伤及出血。

In recent years, bariatric and metabolic surgery has developed rapidly in China. However, due to the small operating space for obese patients, the short splenic-gastric ligament, and abnormal anatomy of some superior splenic arteries, it is easy to damage the superior splenic artery during the process of freeing the body and fundus of the stomach. Once bleeding occurs, it is very difficult to stop the bleeding. In this paper, based on the clinical experience of our center, we review the relevant anatomy around the gastric fundus, hoping to attract the attention of bariatric and metabolic surgeons, so as to effectively avoid intraoperative injury and bleeding of the superior splenic artery as much as possible.
