Abstract
To investigate the effects of freezing the area of first porta hepatis which involves Glisson duct system,16 pigs were randomly divided into 2 groups. Group A:structures of the first porta hepatis were frozen by a dish-like cryoprobe (D=3.0cm) with temporary blockage of hepatic portal blood during freezing,the temperature at the end of 1,2,3minutes of cryotherapy was -50℃,-110℃,-131℃.Group B:sham operation,only with hepatic portal blockage for 3 minutes. Liver function tests,99mTc-EHIDA scintiscanning,and pathological observation were used to evaluate the effects of the cryosurgery postoperatively.The results showed that the bile duct systems on first porta hepatis were severely destroyed by the cryosurgery,the cryoimpairment of common bile duct and/or common hepatic duct led to complications of progressive, irreversible, cryptic necrosis, fistula and pyogenic angiocholitis. The large freezing necrotic lesion in the porta hepatis might compress the portal vein. The perfect protection of biliary system should be accomplished in the cryosurgery of the first porta hepatis to avoid severe complications.关键词
