Patients with cholelithiasis surgery should be given very little drainage 2-3 days postoperatively, without bleeding or biliary fistulae, and should be removed as soon as possible. t-tubes are placed inside the common bile duct, and t-tubes are usually removed in more than 2-3 weeks. Gallbladder removal is usually done without drains. Modern surgical ERAS is the concept of accelerated recovery, which is also very important. There are some patients with laparoscopic drains, who have very heavy inflammation or not only cholecystectomy, but also some patients who have had biliary ducts opened and stones removed or liver lobes or segments removed due to cholelithiasis, who need to have drains placed to drain the exudate from the surgical wound, and patients with biliary fistula or patients with bleeding, who can be observed through the drains and given timely and appropriate treatment. In principle, the sooner the abdominal drainage tube can be removed, the better it is for the patient, because the tube is connected to the abdominal cavity and can cause problems if left in place for too long.
