The new minimally invasive gallbladder preservation treatment for gallbladder stones and polyps, retaining the useful gallbladder With the improvement of people’s living standards, there is an obvious rising trend of cholecystitis, gallbladder stones and gallbladder polyps, and gallbladder removal for gallbladder lesions has been used in clinical practice for more than 100 years. With the rapid development of medicine, especially endoscopic technology, molecular biology, immunology and minimally invasive medicine, the field of surgery has made great progress and broken through many restricted areas. New technologies and new thinking were actively accepted. People have a better understanding of the gallbladder, an important digestive organ, which is a complex organ with chemical and immunological functions, in addition to its role of concentration, contraction and regulation of buffer bile duct pressure. The Department of Surgery of our hospital is the first to carry out minimally invasive gallbladder preservation treatment for gallbladder stones and gallbladder polyps in the city, adopting a high-tech, new technology, using fiberoptic choledochoscope to enter the gallbladder and completely and thoroughly remove the stones under the direct view of the choledochoscope. Compared with open cholecystectomy and laparoscopic cholecystectomy, minimally invasive cholecystectomy preserves the physiological function of the gallbladder and has the advantages of less damage, complete preservation of the gallbladder, complete stone extraction, shorter hospital stay, faster recovery and fewer complications. Endoscopic minimally invasive gallbladder stone (polyp) removal surgery has been carried out in most areas of China. Retaining the useful gallbladder allows gallbladder stone patients to live as healthy as normal people after surgery.
