In the body, gallbladder is a place to store bile produced from the liver. The gallbladder often has to be removed (by open surgery or laparoscopic surgery) when it is acutely or chronically infected, has stones, atrophy or gallbladder cancer... After gallbladder surgery, the patient may experience some problems in the digestive tract and cause some complications that need to be monitored and intervened (if necessary).
