Background

Clinical application drainage system drainage body fluid, digestive juice, excrement and pus are one of the main work of surgery, and surgical drainage is to guide out the liquid accumulated in human body tissue or body cavity to control infection, promote wound healing, reduce postoperative complications and relieve discomfort symptoms caused by liquid space occupying effect.

With the development of minimally invasive technology, the T-shaped tube drainage for choledocholithiasis under laparoscope has become a conventional surgical method for hepatobiliary surgery, generally, a trimmed T-shaped tube is retained in a bile duct after surgery and the wall of the bile duct is sutured, an abdominal cavity drainage tube is placed on a wound surface for cooperative drainage, and the occurrence of postoperative complications is reduced and prevented. The laparoscopic suturing technology is one of the key points of the success of the operation, the inflammation of the bile duct wall of a part of patients is serious, the wall thickness of the bile duct reaches more than 3mm, the laparoscopic suturing is more difficult, the probability of bile leakage after the operation is very high when no suturing is carried out, and the non-conventional suturing can cause the occurrence of various recent and long-term accidents and complications after the operation, thereby increasing the pain of the patients and the hospitalization cost. The drainage tubes are arranged at two parts of the body wall after operation, which brings more inconvenience and pain to patients, the probability of tube falling after the operation is increased due to the plurality of drainage tubes, even if the drainage tubes are pulled out, inflammatory scars at the positions where the drainage tubes are placed are obvious, the recovery of the patients after the operation is slow, and the skin at the drainage positions is not beautiful in a long term.

In summary, the existing patients with serious inflammation of the biliary duct wall need to be intubated for drainage after an operation, and need to be provided with drainage tubes at two parts of the body wall after the operation, the two intubation tubes on the body of the patients can influence each other after the operation, the postoperative pain of the patients can be doubled, and the probability of tube detachment can be increased.
