After cholecystectomy, some patients have post-biliary syndrome, manifested as gastric distension, indigestion and diarrhea, which is a normal phenomenon and need not be too worried, and these symptoms may be reduced or disappear with the extension of time. In the early stage, even if there is obvious gastric distension, only regular checkups are needed, and if necessary, medical treatment is feasible, including cholestasis, liver protection, and digestion promotion. If the patient has a heavy psychological stress burden, he or she can be hospitalized for examination, MRI to understand the presence of common bile duct stones or other lesions, and gastroscopy to understand the lesions in the stomach. Overall, this stomach distension is normal, mostly due to the disappearance of the digestive function of the gallbladder after cholecystectomy, and in the early stage the function of the common bile duct instead of the gallbladder has not fully recovered, so don’t worry too much.
