The gallbladder is an important digestive organ of the body, and some patients with gallbladder stones, especially those with gallbladder polyps, have normal gallbladder function. Therefore, the easy removal of the gallbladder and the loss of gallbladder function will invite all kinds of maladies after cholecystectomy. Therefore, it is necessary to treat gallbladder disease and preserve the gallbladder, which is in line with the concept of modern surgery to protect the function of the organ as much as possible. The textbook of university surgery “General Introduction to Surgery” edited by Prof. Yangde Zhang published in August 2007 has this content: “Minimally invasive endoscopic biliary surgery refers to the exposure of the gallbladder through laparoscopy or small surgical incisions, and the use of cholangioscopy to enter the gallbladder cavity to examine and treat the gallbladder directly. This method is designed to preserve the gallbladder for the treatment of diseases. This method overcomes the fatal blind spot of the old method of gallbladder stone extraction. Currently, it is mainly used for the treatment of gallbladder stones and gallbladder polyps”. As the name implies, gallbladder preservation surgery is a procedure to treat gallbladder stones or gallbladder polyps without removing the gallbladder. In the 1980s and 1990s, there was an attempt to preserve the gallbladder by “gallbladder stone removal”, which is the old-fashioned biliary lithotripsy. But unfortunately, the recurrence rate of gallbladder stones after surgery is very high. After more than 10 years of careful exploration and research, we found that the secret of the high recurrence rate after the old-style biliary stone extraction is not the recurrence rate, but the residual rate, because the surgeon did not remove the stones. Because the old biliary lithotripsy is a “blind exploration” method, it cannot see the internal situation of the gallbladder and cannot guarantee the removal of net stones; furthermore, the stones are mostly taken by lithotripter, which is easy to shatter the stones, so stones are inevitably missed and form gallbladder stone residues. The new endoscopic minimally invasive biliary lithotripsy eliminates the disadvantages of the old method of indirect bedside ultrasound positioning and large incision, and under the direct view of laparoscope, accurately selects the best location for the smallest incision, quickly puts forward the gallbladder, and uses the breakthrough “biliary soft and hard mirror combined stone extraction”, and uses the matching mesh basket biopsy forceps to remove the stones. The “one net” is used to remove the stones. The gallbladder incision is closed in one stage, and no fistula is placed in the gallbladder after surgery. It reduces the recurrence rate of stones from more than 50% to 2%-7%. The treatment of gallbladder stones and gallbladder polyps with new endoscopic minimally invasive gallbladder preservation technology is the least traumatic, with small abdominal incisions, no cutting of abdominal wall muscles, short postoperative fasting time, which preserves the function of the gallbladder, short hospitalization time, and saves time and money. Gallbladder stone preservation surgery: 1.Small incision biliary stone extraction v polyp removalw surgery; 2.Laparoscopic assisted small incision biliary stone extraction; 3.Complete laparoscopic biliary stone extraction. Indications for gallbladder stone preservation surgery: 1, symptomatic and asymptomatic single or multiple stone gallbladder; 2, good function; 3, gallbladder wall thickness ≤ 4mm; 4, bile duct patency; 5, informed consent of patients and families At present, our department has been the first in the province to carry out this technology for two years. The new endoscopic minimally invasive bile preservation technology will definitely create a new era in the treatment of gallbladder stones and gallbladder polyps!
