Abstract:

Laparoscopic sleeve gastrectomy (LSG) has become a widely performed metabolic and bariatric surgery worldwide. The characteristic of this surgical method is that it does not change the natural direction of the gastrointestinal tract, and is simple to operate. Compared with surgical methods such as gastric bypass, it has the same significant weight loss and hypoglycemic effect. More importantly, patients with LSG have fewer long-term complications such as nutritional deficiency. However, gastroesophageal reflux disease (GERD) is one of the main complications after LSG, which has a negative impact on the surgical effect and the quality of life of patients, and may even become the main reason for secondary surgery. Therefore, how to reduce the occurrence of GERD after LSG has become a research hotspot in the field of bariatric metabolic surgery. This article explores the clinical significance of preserving the integrity of the His angle in reducing the occurrence of postoperative GERD in LSG surgery by reviewing the anatomical structure and physiological function of the gastroesophageal junction and the His angle.
