End-to-side anastomosis of the biliary sheath to the Roux-en-Y jejunum limb. The range of the “basin” was determined by the distance between the multiple bile ducts, which can only envelop the bile ducts. Therefore, the wall of the “basin” includes the outside part of the bile duct and the connective tissue and sheath of the Glisson pedicle. a Continuous single-layer sutures of the posterior wall of the anastomosis. Bile duct walls on the posterior wall and the sheath of the connective tissue and sheath of the Glisson pedicle were sutured with the jejunum limb. b Continuous single-layer sutures of the anterior wall of the anastomosis after completion of the posterior wall with another independent PDS or Proline stitch. The stitch was tied up to posterior one to complete the entire anastomosis
