Objective To observe whether coagulation zones can be produced by intraductal radiofrequency ablation (RFA) in vivo and investigate the effect of portal blood flow on the sizes of coagulation zones. Methods Fourteen bile duct targets in hepatic hilar from 6 swines were equally divided into non-Pringle manoeuvre group and Pringle manoeuvre group. A 13mm segment of non-insulated mono-electrode was inserted into the bile duct, then RFA was performed under the condition of 5 W power output for 4 minutes. The pathological changes of bile duct and adjacent hepatic tissues were observed. Results Semi-oval offwhite coagulation zones in the sections were observed in both groups, with obvious dark-red rims around them. Necrosis and denaturation of mucosal and submucosal layers of bile duct and denaturation of adjacent hepatic tissue in coagulation zones were observed under optical microscope. The dark-red rims revealed hepatic hemorrhage. The mean long axial diameter of coagulation zones in the non-Pringle manoeuvre group and Pringle manoeuvre group was (13.29±1.38)mm and (13.29±1.1 1)mm, respectively, with no statistical difference (t=0.000, P>0.05). The mean short axial diameter of coagulation zones in the non-Pringle manoeuvre group and Pringle manoeuvre group was (3.14±1.07)mm and (4.57±0.98)mm, respectively, with statistical difference (t=2.611, P<0.05). Conclusions Intraductal RFA can produce a typical ablation zone. The portal blood flow affects the short axial diameter of coagulation zone but does not affect the long axial diameter.

Objective:To observe the complications caused by radiofrequency ablation (RFA) after RFA via the lumen of bile duct in hilum hepatis and the pathological progress of the tissue in ablation zones. Methods: Fourteen healthy dogs were randomly divided into 2 groups with 7 dogs each group. RFA by inserting a 13 mm non-insulated mono-electrode into the lumen of bile duct was performed under general anesthesia on 10 W power output, 4 min ablation duration in group Ⅰand on 5 W power output, 8 min ablation duration in group Ⅱ. After RFA, 2 dogs were sacrificed in 3 days and 1 dog in 9 days and 4 dogs in 14 days respectively in each group. The complications concerning RFA such as bile leakage, cholelithiasis, hepatic artery thrombosis, portal vein thrombosis, hepatic vein thrombosis1 and vena cava thrombosis were observed. Results: Portal vein thrombosis, hepatic vein thrombosis and vena cava thrombosis occurred in one dog. Cholelithisis occurred in one dos. No hepatic artery thrombosis occurred in all dogs. No bile leakage caused by RFA occurred in all dogs. Obvious necrosis of the mucosal and submucosal layers of the wall of bile duct and hepatic tissue in coagulation zones occurred in 3 days after RFA. The infiltration of inflammatory cells and partial fibrosis of the mucosal and submucosal layers of bile duct and hepatic tissue occurred in 9 days after RFA. Obvious fibrosis of the wall of bile duct and hepatic tissue occurred in 14 days after RFA. Conclusions: The complications caused by RFA occur seldom after RFA via the lumen of bile duct. The necrosis, the infiltration of inflammatory cells and gradual fibrosis of the mucosal and submucosal layers of bile duct and hepatic tissue occur in ablation zone.

Objective To observe the clinical effect of tigecycline combined with cefoperazone sulbactam for the treatment of pneumonia caused by muitidrug-resistant acinetobacter baumannii pneumonia. Methods 68 patients with muitidrug-resistant acinetobacter baumannii pneumonia were randomly divided into two groups, control group and observation group, with 34 patients in each group. The control group was treated with cefoperazone sulbactam, and the observation group was treated with tigecycline combined with cefoperazone sulbactam. The level of PCT, CRP, WBC and clinical cure rates, as well as microbiological eradication and side effect, before and after treatment were collected and compared. Results After treatment, the level of PCT, WBC and CRP in two groups was decreased, and the observation group was more significant than the control group(P < 0.05). The side effect rate in two groups were 14.7% and 17.6% respectively (P > 0.05), while the clinical cure rates and microbiological eradication in observation group were significantly higher than the control group (P<0.05). Conclusion With a higher rate of clinical efficacy and a lower rate of side effect, the combination treatment with tigecycline and cefoperazone sulbactam would be a promising alternative for the treatment of muitidrug-resistant acinetobacter baumannii pneumonia infection.
