To study the effects of monopolar diathermy on the bile ducts in pigs.
Experimental study.
University hospital, Norway.
18 pigs.
Laparotomy, application of diathermy at standard sites along the cystic duct, the bile ducts, and a cystic duct containing a metal clip, 3 to 12 times of 5 seconds' duration at each site. Temperature was subsequently recorded at standard measurement points on the bile ducts. Twelve pigs were killed after three weeks for assessment of the bile ducts at necropsy.
Increase in temperature in the bile duct walls and late changes in the bile ducts.
Temperature increased by 4-6 degrees C during 6 of 330 diathermy applications along the cystic duct, by 4-18 degrees C in 8 of 126 applications along the common bile duct, and by 4-11 degrees C at the clip in 9 of 54 applications. There were no macroscopic or microscopic changes in the bile ducts.
Monopolar diathermy induced unexpected distant increases in the temperature of the bile duct walls and at a clip on the cystic duct probably because diathermy current energy was distributed along channels of high current conductivity.
研究单极透热疗法对猪胆管的影响。
实验研究。
挪威大学医院。
18头猪。
剖腹术，在胆囊管、胆管以及一个夹有金属夹的胆囊管的标准部位进行透热治疗，每个部位持续5秒，进行3至12次。随后在胆管的标准测量点记录温度。三周后处死12头猪，在尸检时评估胆管情况。
胆管壁温度升高以及胆管的后期变化。
在沿胆囊管进行的330次透热治疗中，有6次胆管壁温度升高4 - 6摄氏度；在沿胆总管进行的126次治疗中，有8次温度升高4 - 18摄氏度；在夹有金属夹的部位进行的54次治疗中，有9次温度升高4 - 11摄氏度。胆管未见宏观或微观变化。
单极透热疗法导致胆管壁温度意外地远距离升高，以及胆囊管上金属夹处温度升高，可能是因为透热电流能量沿高电导率通道分布。
