RESUMO

Objective To contrastively study the effects of NERC-300 high frequency welding device and ultrasonic scalpel in rat partial hepatectomy.Methods Forty-eight rats were divided into the experimental group and control group(n=24).The experimental group applied NERC-300 high frequency welding instrument for conducting partial hepatectomy,while the control group used ultrasonic scalpel.The survival rate,operation time,bleeding volume,working temperature,extent of hepatic thermal damage and change of liver function on 1,3,7 d were compared between the two groups.Results The liver function recovery on 3 d in the experimental group was superior to the control group (P<0.05).The intra-operative working temperature in the experimental group was lower than that in the control group(P<0.05).The thermal damage range in the experimental group was lower than that in the control group(P<0.05).The survival rate,operation time,bleeding volume and liver function change on 1,7 d had no statistical differences between the two groups(P>0.05).Conclusion NERC-300 high frequency welding device is safe and effective for partial hepatectomy in rat.

RESUMO

Objective To evaluate the clinical effect and security of cold-circulated microwave scapel on adrenal gland metastatic tumor. Methods Twenty-four focuses in 23 patients were treated,including 3 focuses diameter ≤2.0 cm, 17 focuses diameter 2.1 - 3.9 cm, 3 focuses diameter 4.0 - 5.9 cm,1 focus diameter ≥ 6.0 cm, the effects were evaluated by spiral CT scanning 1 month after treatment. Results The number of total necrosis focuses diameter ≤2.0,2.1 -3.9,4.0 -5.9, ≥6.0 cm after treatment were respectively 3, 17, 1, 0. In addition, not fully necrosis were 0, 0, 2, 0 and partial necrosis were 0, 0, 0,1. Fifteen cases after ablation treatment marked varying degrees of pain in the region, 3 cases of high blood pressure patients,4 cases occurred with Ⅰ - Ⅱ degree skin bums. The above cases were easing after symptomatic treatment. Conclusion The treatment of cold-circulated microwave scapel is secure,it is one of an effective method to adrenal gland metastatic tumor,with little adverse reaction.

RESUMO

Objective To explore the value of Ligasure vessel sealing system(LVSS)during resection of retroperitoneal tumor.Methods Group 1 including 32 cases were performed resection of retroperitoneal tumor with LVSS and electrosurgical seapel from Jun.2004 to Oct.2008.group 2 including 26 cases were done with electrosurgieal seapel from Jan.2001 to Jun.2004.Operating blood loss,operating time,iatrogenic injury,postoperative blood loss and hospital stay were compared between the two groups.Results There was no significant difference in hospital stay[(11.7±0.7)d vs.(12.3±1.4)d)]and iatrogenic injury(9.38%vs.16.00%)between two groups statistically(P>0.05),but the intraoperative blood lose[(403.1±37.1)ml vs.(704.0±129.0)m1)s,postoperative blood loss[(131.5±18.4)ml vs.(214.8±29.2)ml)]and operating time[(166.5±8.9)min vs.(186.8±15.4)min]were less in group 1 than that in group 2(P<0.05).Conclusion Ligasure vessel sealing system has advantages of safe coagulation,shortening operation time in resection of retroperitoneal tumor.
