[Functional evaluation after function-preserving gastrectomy]

With the increase of people's health awareness and the progress of medical diagostic technology in recent years, the diagnosis rate of early gastric cancer is increasing year by year. Although radical surgery has good efficacy, how to maximize the preservation of the normal anatomy and function of the stomach and improve the quality of life of patients in the pursuit of radical surgery has become a more important issue in the treatment of early gastric cancer. Under the condition of ensuring radical lymph node dissection, function-preserving gastrectomy can fully preserve gastric function by reducing the resection extent and preserving the pylorus and the vagus nerve, which has advantage of improving quality of life and has great potential in the treatment of early gastric cancer. However, there is no functional evaluation standard for function-preserving gastrectomy at present. Most of the patients are evaluated by quality of life scale, which is relatively subjective. Even though the evaluation of endoscopy, hematology and other objective means can indicate the benefit degree in quality of life brought by functional reconstruction, the evidence level is limited. Therefore, this paper discusses the research status of function-preserving gastrectomy evaluation, postoperative complications, postoperative nutritional status, auxiliary examination and other items in the evaluation of gastric function, and analyzes the prospects of research direction in this field.
