title: Biliary-enteric anastomosis by means of a single layer of serosubmucosal sutures without T-tube drainage.
abstract: BACKGROUND
  To lessen anastomotic stricture after biliary-enteric anastomosis, we developed a new biliary-enteric anastomosis that uses a single layer of interrupted serosubmucosal sutures without T-tube drainage.
  
  
  OBJECTIVE
  To evaluate the safety and reliability of this new technique in a canine model of choledochoduodenostomy.
  
  
  METHODS
  In 10 beagles, the common bile duct (2 to 3 mm in diameter) was ligated close to the duodenum with 3-0 polyglactin. On the fifth day after operation, the serum bilirubin level was elevated (137 to 205 mumol/L [8 to 12 mg/dL]) and the bile duct was dilated. The anastomosis between serosubmucosal layers of the dilated bile duct (8 to 10 mm in diameter) and duodenum was accomplished with interrupted sutures of 6-0 polyglactin with two needles. Stitches were inserted in the submucosal plane at the cut edge of the duct and duodenum to appose the mucosa accurately and to avoid accidental perforation of the entire thickness of the duct and duodenum. A T tube was not placed.
  
  
  RESULTS
  There was no anastomotic leakage and the bilirubin level was normalized (14 to 17 mumol/L [0.8 to 1.0 mg/dL]) 7 days after operation for anastomosis. Histologic examination of specimens removed 6 or 12 months after operation showed good connective-tissue union and good mucosal continuity between the bile duct and the duodenum. There was no mucosal scarring and contracture or stricture formation.
  
  
  CONCLUSIONS
  This new technique is simple and reliable and is recommended as an alternative method for restoring the continuity between the bile duct and intestinal tract after operation for obstructive jaundice caused by benign and malignant stricture of the bile duct.
