Gallstones still require fluids before minimally invasive surgery. Gallstones require fluids before minimally invasive surgery for several reasons: 1. The infusion can be used as an anti-inflammatory, which can have an anti-infective effect. 2. Fluid infusion before minimally invasive surgery for gallstones also establishes venous access for anesthesia. 3. The patient is in a fasting state before the operation, and the infusion can replenish a certain amount of glucose, saline, etc. for him, so that hypotension and hypoglycemia will occur anyway. Patients can eat a liquid diet 24 hours after minimally invasive surgery for gallstones, and can eat a semi-liquid diet after bowel evacuation. Meanwhile, avoid eating greasy and hard food. After the operation, no strenuous exercise is allowed, and the amount of activity can be increased appropriately after the wound is completely healed. If patients feel severe abdominal pain, nausea, vomiting, jaundice, they should go to the hospital for examination in time to avoid adverse effects.
