The land of China is gradually spreading, and with the development of the economy and the continuous improvement of medical care, the average life expectancy of Chinese people has increased significantly and elderly patients are common. However some diseases are devouring the health of the elderly, such as tumors, cardiovascular diseases, osteoporosis, etc. According to statistics, the incidence of acute cholecystitis in elderly patients over 70 years of age is about 13-50%, and these patients usually have hypertension, diabetes, coronary heart disease, cerebral infarction, chronic obstructive pulmonary emphysema and chronic bronchopneumonia in the elderly, etc. Moreover, the symptoms are not typical when starting the disease, which leads to difficulties in diagnosis and delay in treatment, and the end result is acute cholecystitis, which is usually The end result is that acute cholecystitis, which is usually considered a “minor disease”, has claimed the lives of many elderly people. Percutaneous transhepatic cholecystocentesis and drainage (PTGD) is an advanced treatment for geriatric cholecystitis, especially for the treatment of geriatric non-stone cholecystitis, and can achieve curative effects. ). Percutaneous transhepatic cholecystocentesis and drainage is performed by puncturing through the right upper abdomen to the liver and then into the gallbladder through the gallbladder bed to drain the bile out of the body. PTGD is a minimally invasive method to rapidly drain infected bile and reduce pressure in the gallbladder cavity, thereby reducing toxin absorption and alleviating toxic symptoms. After the pressure of the gallbladder is relieved, the patient’s abdominal pain and distension are obviously relieved. In addition, after the gallbladder is decompressed, the bile can flow smoothly into the intestine and the patient can eat after surgery. For patients with acute cholecystitis, especially those with cardiopulmonary and cerebral insufficiency, percutaneous transhepatic cholecystocentesis and drainage can not only avoid the great risks associated with emergency cholecystectomy or cholecystostomy, but also rapidly relieve the symptoms and control the infection. It is a safe, effective, and easy treatment method for managing elderly patients with acute cholecystitis combined with high-risk factors.
