Thermal coagulation of puncture lesions in the cholestatic rabbit liver with Nd: YAG laser and and high-frequency current.
The coagulatory effect of the Nd: YAG laser after puncture of the cholestatic liver was compared with the effect of electrocoagulation. In 11 rabbits, the liver was punctured 7 days after ligature of the common bile duct with a Menghini needle 1.2 mm. The site of injury was coagulated by laser light in 5 animals and by unipolar electrocoagulation in 6 animals. Bleeding and bile leakage was stopped in all cases. Histologically there was no crucial difference between the two methods in their effect on the liver tissue. Autopsy 14 days after common bile duct ligature revealed no bile peritonitis in any rabbit.
