Pain in the stomach after cholecystectomy may be due to a peptic ulcer, bile reflux, and bile duct stones. 1. Pain in the stomach after cholecystectomy may be a simple gastric ulcer unrelated to the surgery. To determine the exact condition, you can consult your doctor at the hospital and have the appropriate tests done to confirm the diagnosis. 2. After cholecystectomy, if the bile produced by the liver is not concentrated and goes directly into the digestive tract, it may cause disorders in the function of the digestive tract. The digestive juices in the duodenum, such as bile and pancreatic juices, may reflux to the stomach, causing stomach acidity, stomach pain or bloating and other stomach discomfort. 3. After cholecystectomy, stones may remain in the bile duct. These stones block the flow of bile in the bile ducts, causing pressure in the bile ducts to increase and cause pain. Since the location of the bile duct is adjacent to the stomach, pain in the bile duct may be mistaken for pain in the stomach. There are many reasons for the feeling of pain in the stomach after cholecystectomy, and you need to consult your doctor in the hospital for specific tests before treatment.
