两类手术应用被国家卫健委叫停，涉阿尔茨海默病、糖尿病

Core Viewpoint - The National Health Commission has prohibited the use of jejunoileal anastomosis for the treatment of type 2 diabetes and cervical deep lymphatic/lymph node-venous anastomosis for Alzheimer's disease treatment due to safety and efficacy concerns [1][2] Group 1: Jejunoileal Anastomosis - The jejunoileal anastomosis is primarily used for intestinal obstruction, tumor resection reconstruction, or congenital deformity repair, but its application in diabetes treatment has been deemed unsafe and ineffective [1][2] - The procedure may lead to severe complications such as liver failure and malnutrition, and it has been eliminated from clinical use in the weight loss metabolic field due to high complication rates [2] Group 2: Cervical Deep Lymphatic/Lymph Node-Venous Anastomosis - The cervical deep lymphatic/lymph node-venous anastomosis lacks direct evidence from preclinical studies for its application in Alzheimer's disease treatment, and it is still in the early exploratory stage of clinical research [2] - Local health authorities are required to investigate the clinical application of this procedure and ensure that medical institutions immediately cease its use while enhancing regulatory oversight [2]
