Chronic cholecystitis often occurs due to the presence of gallbladder stones. Due to long-term inflammation, the gallbladder wall thickens and loses its contractile function, and the gallbladder cannot store and excrete bile properly. In severe cases, the gallbladder atrophies. Chronic cholecystitis often has a history of biliary colic in the past, with frequent gastrointestinal symptoms such as bloating, aversion to oily food, belching, and sometimes right upper abdominal pain, chills, and fever. Ultrasonography may reveal gallbladder shrinkage, deformation, or stones. If the condition is severe and accompanied by gallbladder stones, it is best to have the gallbladder removed surgically. For chronic cholecystitis, surgery is usually performed 2-3 months after the pain attack is completely relieved, because the inflammation of the gallbladder can only disappear completely at this time and the surgery is relatively safe. Currently there are two types of surgical removal of the gallbladder: open surgery and laparoscopic surgery. Open surgery has a history of 100 years and is a classic surgical method. Laparoscopic surgery is a new method developed in the last 20 years, in which the gallbladder is removed through 3-4 small holes in the abdomen and special instruments are inserted, which has the advantage of less trauma and faster postoperative recovery, but has special requirements for the surgeon’s skills, slightly higher surgical costs, and requires special equipment. The laparoscopic surgery is not suitable for patients with severe cardiopulmonary disease, hernia, peritonitis, severe chronic cholecystitis, etc.
