Value of intraoperation bile leakage test in preventing postoperation bile leakage after liver resection / 中国综合临床

Objectiye To evaluate the value of intraoperative bile leakage test during liver resection in preventing postoperation bile leakage. Methods Eighty-one cases were randomly divided into two groups,in the test group (41 cases) white fat emulsion(sterilized) was injected into common bile tract through cyst bile duct,the leakage points on the transect surface were observed and disposed. In the control group (40 cases) the transect surface were disposed by regular methods. The rate of postoperation bile leakage in the two groups were analyzed. Results The rate of postoperation bile leakage in the test group was 2. 4% (n=1), and the rate of postoperation bile leakage in the control group was 15% (n = 6). There was significant difference between the two groups (x2=4.04, P＜0.05). Conclusion The white bile leakage test is effective in preventing the postoperation bile leakage during liver resection and does not increase other complications.

Leakage Burn and Electric Appliance Security from High-frequency Electrotome / 医疗卫生装备

The electrotome is a kind of medical surgical operation instrument, which can be applied to incision and electrocoagulation of tissues. From the aspect of circuit structure, high-frequency electrotome is divided into three types, that is, spark type, valve type and semiconductor type. The third one poses its future at miniaturization, high power and intelligentization. As the development of electrotome, some surgical accidents come up, such as electrical leakage, leakage burn and electric appliance security. So more and more attention is paid to the application security of high -frequency electrotome. The test method and some burn and leakage examples of electrotome are introduced and analyzed in the paper.
