The gallbladder is by no means dispensable, but an organ with important functions. And the removal of the gallbladder brings about numerous physiological defects and immune function effects. So, why must the gallbladder be removed to treat gallbladder stones? Because they believe that the method of preserving the gallbladder has such a high recurrence rate after surgery that it is equivalent to doing it for nothing. However, is the recurrence rate really very high? No, it is not. Today, 100 years later, we have uncovered the secret of easy recurrence of old-fashioned biliary stone extraction, and effective measures have been taken in treatment to solve the recurrence problem, and biliary stone extraction has become a realistic and feasible method. The main significance of the new concept of biliary lithotripsy is to remove the stones and maintain the normal balance and physiological function of the body. Of course, it also fully embodies the concept of “minimal trauma”. Strictly speaking, the so-called “minimally invasive” mainly refers to the size of the damage to the organ function, while the size of the incision is of secondary importance. Preserving the function of an important organ is the most important criterion for minimally invasive surgery. If the gallbladder organ is cut off and its function is lost, even if the incision is small and the recovery is fast, it cannot be considered minimally invasive and should be severely invasive. Another feature of the new type of gallstone removal surgery is that it is very safe. This surgery has no serious comorbidities and no mortality. This is incomparable to any cholecystectomy surgery at present. This is one of the most important concerns of patients. At the same time, the new type of biliary lithotomy, for those cases where the gallbladder is no longer functional, the gallbladder is atrophied, and the gallbladder is cancerous then the gallbladder should be removed without hesitation. Of course, the new endoscopic minimally invasive biliary stone extraction method, in addition to reflecting the minimally invasive spirit of preserving the function of the gallbladder, also reflects the small incision, light trauma, fast recovery and good cosmetic appearance, which is welcomed by the majority of patients. In contrast to traditional cholecystectomy, where the incision length is 15-20 cm and the stitches need to be removed after surgery, and a large scar is left behind, the new biliary surgery has a small incision, the smallest being up to 2 cm, and the scar is not visible after surgery, which has a strong cosmetic effect and is favored by young people, especially young women, with the emphasis on humanization. . Therefore, the endoscopic minimally invasive biliary stone/polyp removal technique is a high-tech, new technology and a new concept with unlimited vitality. It can withstand repeated clinical trials and is warmly and sincerely welcomed by patients. In the past, the treatment for gallbladder stones was mainly surgical, with the removal of the gallbladder, which was unmistakable. However, in the last 20 years, due to the rapid development of modern high-tech technology coupled with advances in other medical fields, various drawbacks of gallbladder removal have been discovered. Various methods have emerged to preserve the gallbladder to remove stones and polyps. With the development and advancement of endoscopic technology, the endoscope can look directly into the internal situation of the bile duct, which has given a great impetus to the diagnosis and treatment of biliary diseases. “Endoscopic minimally invasive bile stone extraction” is to use a soft (fiber) cholangioscope to enter the gallbladder for examination and treatment, the fiber cholangioscope can be bent at will, and can be illuminated and observed, where there are stones can be taken, to achieve safe and complete removal of stones, the treatment results are real and reliable. The endoscopic minimally invasive bile stone removal incision is small and lightly damaged, and you can get out of bed the next day after surgery and be discharged from the hospital after 3 days. Gallbladder polyp is a common and frequent disease in clinical practice. The treatment method can only be completed on the basis of endoscopic technology to observe the polyps under minimally invasive conditions, remove the polyps, and confirm the diagnosis of pathology so as to scientifically decide whether to preserve the gallbladder or remove it. This method is the least invasive method for the treatment of gallbladder polyps, with small abdominal incisions, one-stage suturing of the gallbladder incision, without placing any fistula, small skin incisions with mucous plasters pulled together, and no stitches removed after the operation; the patient can be discharged from the hospital in 2-3 days.
