Cholecystectomy surgical intubation is an abdominal drain put in place to facilitate clinical observation of the occurrence of bleeding, infection and cholecystic fistula in order to facilitate the timely administration of clinical treatment. In clinical practice, the need for postoperative drainage tubes is generally determined by the patient’s physical condition and the surgical procedure, for example, most laparoscopic surgeries have less postoperative damage and are not considered to have associated complications based on clinical assessment, so drainage tube placement is not required. However, some of the intraoperative injuries are large and suspected to be prone to related complications, so the drain needs to be left in place. The color and amount of fluid in the drain can be used to determine whether there are symptoms of postoperative rebleeding or infection, and the color of the drain can be used to determine whether there is a biliary fistula or not. Drainage tubes can help doctors to detect changes in the condition at an early stage and take appropriate treatment to avoid life-threatening injuries due to delayed condition. Therefore, clinically, we should follow the doctor’s instructions, do not pull out the tube by yourself and other dangerous operations.
