Background: Orthotopic liver transplantation (OLT) models in rats have been investigated in many studies. The reconstruction of hepatic artery is required for reliable OLT and also requires advanced skills.
Methods: The hepatic artery reconstructions by a hand-suture technique and a new method using a micro T-tube were investigated in rats with a whole-liver syngeneic graft. Operative time and postoperative patency were compared between the hand-suture and micro T-tube techniques.
Results: Our technique using the micro T-tube shortened the operative time of recipient surgery compared with the hand-suture technique and prolonged the operative time for the donor. The patency ratio was maintained at 24h after OLT with hand suturing but was significantly reduced with the micro T-tube, which had a patency ratio of 0.83 only up to 6h after OLT.
Conclusion: The micro T-tube technique may have potential usefulness in the rat OLT model but requires further modification.

Background: Laparoscopic transcystic common bile duct exploration has become a safe and ideal treatment of common bile duct stones. This study was designed to explore the clinical value of modified laparoscopic transcystic common bile duct exploration as a first line of treatment for patients with common bile duct stones.
Patients And Methods: A retrospective, case-control study of clinically comparable groups of patients who underwent the laparoscopic transcystic approach with micro-incision of the cystic duct and its confluence part in common bile duct exploration (LTM-CBD) (n=110) and laparoscopic common bile duct exploration (LCBD) (n=100) under the care of one surgeon was performed.

Cholesystolithiasis is often associated with common bile duct stones (CBDS). In order to assess the choice of surgery in terms of effectiveness and complications in the treatment of CBDS, we have compared three surgical procedures, viz., laparoscopic choledocholithotomy T-tube drainage (LCH-TD), laparoscopic cholecystectomy with endoscopic sphincterotomy (LC-EST), and the traditional open choledocholithotomy with T-tube drainage (OCHTD).
