Advanced Roux-en-Y hepaticojejunostomy with magnetic compressive anastomats in obstructive jaundice dog models.

ABSTRACT:

Background

Although commonly used procedure, Roux-en-Y hepaticojejunostomy (RYHJ) remains to be complicated, time consuming, and has a relatively poor prognosis. We designed the magnetic compressive anastomats (MCAs) to perform RYHJ more efficiently and safely.

Materials and methods

36 dogs were divided into two groups randomly. After obstructive jaundice model construction, RYHJ was performed with MCAs in study group or by hand-sewn in control group. Both groups were followed for 1, 3, and 6 months after RYHJ. The liver function and postoperative complications were recorded throughout the follow-up. At the end of each time point, dogs were sent for magnetic resonance imaging (MRI) and sacrificed. Anastomotic samples were taken for anastomotic narrowing rate calculation, his
