Vascular closure staples-a new technique for biliary reconstruction: prospective randomized comparison with manual suture in an animal model.

Background: In orthotopic liver transplantation the incidence of biliary complications is up to 49%. In view of the relative frequency of such complications despite seemingly good preconditions, method-related disadvantages of conventional suture must also be considered as a possible cause. These include perforating needle injury of the choledochal wall with at least temporary exposure of suture material in the lumen, suboptimal approximation of the mucosa, and an additional decrease in blood flow in the choledochal stumps as a result of suture-related tissue strangulation.

Laparoscopic surgical technique for repair of rectal and colonic tears in horses: an experimental study.

Objective: To determine the efficacy of laparoscopic surgical techniques for repair of rectal lacerations in horses.

Study Design: Experimental study.

Animal Or Sample Population: Thirty-two segments of equine bowel placed in an equine pelvitrainer, 8 equine cadavers, and 3 normal horses.

[Biliary endo-to-end anastomosis with extramucosal titanium clips. Initial results of a new technique].

Background: Bile duct anastomoses are still associated with a high failure rate. Although following iatrogenic bile duct transection only a positive selected group of patients get a primary end-to-end reconstruction, long-term results demonstrate an incidence of postoperative strictures up to 78%. Also in orthotopic liver transplantation biliary tract complications remain a significant cause of morbidity with an incidence of up to 49%.

Vascular injuries within the hepatoduodenal ligament: recognition by laparoscopic color Doppler ultrasound.

Background: Lesions of vascular structures are rare but serious complications of laparoscopic cholecystectomy. The purpose of this blind randomized animal study was to investigate the possibility of detecting different vascular lesions within the hepatoduodenal ligament using laparoscopic color Doppler ultrasound (LCDU).

Methods: Twenty-four lesions of the hepatic artery and portal vein were created laparoscopically in six farmer pigs using titanium clips.

Laparoscopic ultrasonography reliably visualizes bile-duct injuries - a blind randomized porcine study.

Introduction: Despite use of intraoperative cholangiography (IOC), only one-third or less of bile duct injuries that occur during laparoscopic cholecystectomy are detected at the primary operation. Therefore, there is a need to investigate other intraoperative diagnostic methods, especially laparoscopic ultrasound, for detecting bile-duct injuries.

Materials And Methods: Detection of different bile-duct injuries by laparoscopic intraoperative ultrasonography was evaluated in a blind, randomized animal study.

[Determination of fibrinogen levels in the horse with the heat-precipitation methods of Schalm and Millar].

The purpose of this study was to investigate the usefulness of two heat-precipitation techniques (Schalm- and Millar-method) as screening tests to measure plasma fibrinogen concentration in horses. Based on the measurement of samples from 108 different horses, the coefficient of correlation (CC) for the relationship between the results with the Schalm- and with the reference-method (Jacobsson) were much lower (r = 0.78) than between the Millar- and Jacobsson-method (r = 0.
