Background: Laparoscopic cholangiojejunostomy (LCJ) with hand-sewn technique is technically difficult and requires a long time to master. The purpose of this study was to assess the feasibility of LCJ using a novel magnetic compression device (MCD) in dogs.
Methods: The concept of the purse-string technique of the circular stapler was used to design a novel MCD for LCJ. To test the feasibility of this MCD in a more clinically relevant situation, four dogs were subjected to bile duct ligation. When the diameter of their bile ducts reached 10 mm, LCJ using MCD was performed. The anastomotic time and expelling time of the magnets were assessed.
Results: In the clinically relevant model of bile duct obstruction in dogs, LCJ created with this MCD yielded patent anastomoses. The LCJ procedure using this novel MCD was simple, and the mean anastomotic time was 12.9 ± 1.73 min. All animals recovered smoothly after the operation without complications. All magnets spontaneously passed through the rectum in 14.5 ± 2.08 d after LCJ.
Conclusions: LCJ in dogs using this novel MCD is feasible.
