What is the difference between acute cholecystitis and chronic cholecystitis? Acute cholecystitis often has an acute onset and progresses rapidly, with patients suffering from abdominal pain, bloating, nausea, vomiting, fever and other symptoms, which can often lead to acute purulent cholecystitis and abdominal infection if not treated in time. Chronic cholecystitis is mostly slow onset, painful symptoms to distension, hidden pain is more common. 2, acute cholecystitis after timely anti-inflammatory, liver protection, antispasmodic treatment, most patients can return to normal, if the acute inflammation is not paid attention to often recurrent episodes, can develop into chronic inflammation. Chronic cholecystitis patients mostly evolve due to repeated attacks of acute inflammation. And drug treatment is not easy to completely cure. Chronic cholecystitis is often recurrent with dense local adhesions of the gallbladder, making surgical separation relatively difficult, and some patients may be at risk of bile duct, intestinal duct, and vascular injury due to unclear local anatomy. This shows that early detection of the disease, early treatment, the effect is often better, must be delayed for a long time, recurrent attacks prognosis is not good.
