Surgery for cholecystitis is usually cholecystectomy, and the after-effects mainly include: abdominal bloating, stones in the common bile duct and so on, and it may also cause gastritis. 1. Bloating: gallbladder is a sac-like organ in the digestive system, once removed, the amount of bile for digesting food will be reduced, which may cause indigestion, followed by bloating symptoms, and may also lead to diarrhea. 2. Common bile duct stones: after the removal of the gallbladder, if the bile is silted up in the common bile duct, patients with stone constitution may develop common bile duct stones, but from long-term clinical observation, this possibility is still very low. 3. Gastritis: After cholecystectomy, bile can reflux into the stomach, thus causing bile reflux gastritis. After cholecystitis surgery, patients need to go to the hospital for regular checkups and follow the doctor’s instructions according to the actual situation.
