Inflammatory factors are considered in postoperative abdominal effusion after gallbladder surgery, and in most cases anti-inflammatory treatment is needed, mainly to prevent infection and relieve local exudate. After cholecystectomy, if the inflammation around the gallbladder is high, it is necessary to place an abdominal drain for drainage of the exudate from the surgical operation area in order to avoid the collection of exudate causing abdominal infection. In addition, postoperative prophylactic application of antibiotic therapy, the so-called anti-inflammatory drug therapy, such as injectable cefuroxime sodium, is also needed to prevent postoperative infection. Generally postoperative prophylactic application of anti-inflammatory drugs such as antibiotics within three days, on the one hand, to prevent postoperative infection, on the other hand, anti-inflammatory drugs can alleviate the inflammatory reaction in the operative area, which in turn reduces the inflammatory exudation. Whether or not anti-inflammatory drugs are needed to treat abdominal fluid after gallbladder surgery still needs to be carried out by the doctor according to the postoperative condition.
