Objective The research is to study the temperature rising situation in the thermochemotherapy process of the domestic dog through the hepatic artery, and the bearing ability of heart, liver, and kidney during the process, as well as the biochemical and histological change of the liver after the procedure. Methods A thermostated container of water bath and an infusion pump, both designed domestically, were adopted. Ten domestic dogs were divided into 2 groups of A and B with 5 dogs respectively. Through hepatic artery infusion for group A, glucose solution (GS) was administered at 43?C for 30 minutes, with the flowing rate of 30ml/min, in group B 5% GS at 45?C for 30 minutes, with the flowing rate of 40ml/min added with chemotherapy drug MMC(0.2mg/kg) was administered to 3 dogs and 5% GS with the same flowing rate added with CDDP(1mg/kg) into other 2 dogs. Results The temperature of anus and liver was 0.3～0.5?C and 0.5～1.0?C higher than before the procedure respectively, there was no significant rate changes of heart and respiration during and before the procedure. Four dogs were radiographied after 15 minutes' infusion, showing different degrees of hepatic artery dilation accompanied with relevant increase of infusion. Six dogs were radiographied after 30 minutes' infusion, 5 of them showed arterial contraction astescal on accompanied with relevant decrease of infusion. There appeared slight or moderate increase of aminopherase after the procedure, but in actually returned to normal within a week. Pathologically, there appeared no acute effect on heart, lung and kidney other than slight and reversible damage to hepatic tissue. Conclusions Healthy dogs can endure the chemotherapy treatment of infusion through hepatic arterial fistula at 43?C 45?C for 30 minutes.

Objective To evaluate the repot of common hepatic duct defect caused by Type Ⅱ or Type Ⅲ Mirizzi syndrome laparoscopically.Methods Eight cases of Type Ⅱ or Type Ⅲ Mirizzi syndrome treated under laparoscopy were analyzed retrospectively.Among them six cases were identified as Mirizzi Ⅱ and a defect on the lateral wall of common hepatic duct was found and repmred by suturing the stubble of cystic duct.The two Mirizzi Ⅲ cases had a defect on front and lateral wall or back and lateral wall of common hepatic duct respectively.Both defects were repaired by a patch from the infundibulum of galllbladder. Results All the 8 cases underwent laparoscopic subtotal cholecystectomy followed by repair of common hepatic duct defect.The operation lasted for 80～150 min(mean 110 min).There was no recurrence of the symptoms after 6～24 months follow up.Conclusion The familiarity of the anatomical characters of Mirizzi syndrome and the skillful suture technique under laparoscopy are both necessary.

Objective To compare the effects of tetracaine or lidocaine anesthesia effect on urethral agita-tion in thoracoscopic male patients during recovery period. Method One hundred and twenty male adults(18 ~60 yr),ASA physical status I and II undergoing elective thoracoscopic surgery ,were randomly divided into three groups of 30 cases in each one. The control group received paraffin oil lubrication catheterization after general anes-thesia induction,whereas the experimental groups received tetracaine gel or lidocaine gel 3~5 g in urethral surface anesthesia before catheterization. Intra-operatively ,urinary catherization was performed with a 16 Fr Foley′s cathe-ter,and a balloon was inflated with 10 mL distilled water. The CRBD was assessed at 0,1,and 12 h after patient′s arrival in the post-anaesthesia care unit. Severity of CRBD was graded as none,mild,moderate and severe. Data were analysed by one-way ANOVA and Fisher′s exact test. P < 0.05 was considered significant. Results Inci-dence and severity of CRBD was reduced in the experimental groups compared with the control group(P < 0.05). Postoperative pain as assessed by visual analogue scale and Richer-SAS was also reduced in the experimental group compared with the control group. Furthermore,in the tetracaine group,catheter-related complaint had less discom-fort than that in the lidocaine group. Conclusion Lidocaine and tetracaine surface anesthesia can significantly reduce catheter-related bladder discomfort after induction ,and tetracaine mucilage lasts for a longer time and less discomfort.
