Intraoperative photos before and after anastomosis. a Before anastomosis, 5 bile duct radicals were lined up and stented with a latex tube. b After anastomosis, all 5 bile duct radicals were inserted and fixed to the jejunum limb. In our current clinical practice, we continue to make improvements based on our experience: (1) 4–0 PDS II or Proline stitches are recommended, while silk stitches are discouraged in an effort to avoid biliary calculus deposition. (2) Insertion of a stent is necessary for every bile duct radical to prevent postoperative stricture. (3) The diameter of the basin-shaped anastomosis should be only sufficiently large to allow every bile duct radical to be inserted; a larger size only causes more irritation to the remnant facet of the liver
