Pain after choledocholithiasis surgery is usually normal and can also be a complication such as an anastomotic fistula. It is normal for any surgery to cause some pain, to a greater or lesser extent, after the anesthetic has finished working. Different people have different levels of pain tolerance, and the pain will gradually disappear in the days after the operation, so there is usually no need to worry too much. In a few cases, postoperative wound infection, anastomotic fistula and other postoperative complications will also bring about corresponding pain. Pain may also occur if there is an infection during the operation or in the wound, leading to inflammation, or if there is a fistula in the anastomosis. In such cases, targeted treatment is required, with reoperation if necessary. If you feel unwell, please consult a doctor.
