Summary
This study demonstrates that laparoscopic cholangiojejunostomy (LCJ) is feasible in dogs using a novel magnetic compression device (MCD). The magnetic compression device simplifies the LCJ procedure, offering a potentially easier method for surgeons.
Area of Science:
- Minimally Invasive Surgery
- Gastrointestinal Surgery
- Surgical Devices
Background:
- Laparoscopic cholangiojejunostomy (LCJ) is a complex procedure requiring extensive surgical expertise.
- Mastering the hand-sewn technique for LCJ is time-consuming and technically demanding.
Purpose of the Study:
- To evaluate the feasibility of performing LCJ using a novel magnetic compression device (MCD).
- To assess the efficacy of the MCD in a canine model simulating bile duct obstruction.
Main Methods:
- A novel MCD was designed based on the purse-string technique of circular staplers.
- LCJ using the MCD was performed on four dogs with induced bile duct obstruction (10 mm diameter).
- Anastomotic time and magnet expulsion time were recorded.
Main Results:
- LCJ with the MCD resulted in patent anastomoses in a clinically relevant canine model.
- The procedure was simplified, with a mean anastomotic time of 12.9 ± 1.73 minutes.
- All dogs recovered without complications, and magnets passed rectally within 14.5 ± 2.08 days.
Conclusions:
- Laparoscopic cholangiojejunostomy using the novel magnetic compression device is feasible in dogs.
- The MCD offers a simpler and potentially faster alternative for LCJ compared to traditional methods.
