When the gallbladder wall becomes inflamed and fibrotic, the gallbladder is contracted, which is known as chronic non-lithotripsy cholecystitis. What are the diseases that are easily confused with it? 1, gallbladder dysmotility is common in the gallbladder duct syndrome, refers to the incomplete, non-stone, mechanical obstruction of the gallbladder duct, causing poor bile drainage, gallbladder pressure increased due to a group of biliary colic as the main manifestation of clinical syndrome. This syndrome is also known as partial obstruction of the cystic duct syndrome, gallbladder motility disorder syndrome, and primary chronic cholecystitis. According to the typical pain, cholecystogram without stones and good gallbladder filling, bile can not be adequately emptied after fatty meal, the gallbladder duct syndrome should be suspected, but to confirm the diagnosis, other auxiliary examinations mentioned above are needed. 2.Thinning of gallbladder wall Papillary adenocarcinoma may come from malignant transformation of papillae or polyps. The tumor grows into the gallbladder cavity and affects the emptying of gallbladder, and there are ulcers on the surface of the tumor, which can easily cause infection. If the tumor obstructs the neck of gallbladder, it can make the gallbladder enlarged and the wall of gallbladder become thin, similar to gallbladder abscess or fluid accumulation. 3.Gallbladder enlargement Patients suffering from acute cholecystitis are often found to have enlarged gallbladder, thickened wall and stones in the gallbladder by ultrasound examination of gallbladder. Acute cholecystitis is an inflammation of the gallbladder caused by obstruction of the gallbladder duct and bacterial attack; its typical clinical features are paroxysmal colic in the right upper abdomen, accompanied by significant tenderness and abdominal muscle tonus. About 95% of the patients have gallbladder stones, called lithotripsy; 5% of the patients do not have gallbladder stones, called non-lithotripsy cholecystitis. 4, poor gallbladder contraction The diagnosis of biliary hypotonia syndrome may reveal poor gallbladder contraction after a fatty meal. Hypotonic biliary tract syndrome, also known as Chiray syndrome, refers to a group of syndromes in which poor digestion, intolerance of fatty foods and right upper abdominal pain occur due to low biliary tract tone and delayed emptying of the gallbladder. This syndrome belongs to the category of biliary dysfunction syndrome, also known as gallbladder retardation syndrome.
