RESUMEN
Objective To compare the safety and efficacy of the 2μm laser and the bipolar electrotome used in transurethral re-section of bladder tumor(TURBT)for treating non-muscle invasive bladder cancer(NMIBC).Methods The clinical data in the pa-tients with NMIBC treated by TURBT in our hospital from March 2009 to May 2013 were retrospectively analyzed.All patients were divided into the 2μum laser group(n=89)and the bipolar electrotome group(n=82).The operation time,complications,post-operative hospital stay and recurrence rate were compared between the two groups.Results There were no statistically significant differences in the operation time,postoperative hospital stay and recurrence rate between the two groups(P>0.05).Compared with the 2 μm laser group,the bipolar electrotome group showed significantly higher occurrence rate of the obturator nerve reflex (20.7%vs.0,P<0.05)and the bladder perforation(7.3% vs.0,P<0.05)and longer postoperative bladder irrigation time [(3.1±0.9)d vs.(2.2±1.0)d,P<0.05],the differences between the two groups had statistical significance.Conclusion Com-pared with bipolar electrotome,the 2μm laser used in TURBT is safe and effective with few complications for treating NMIBC.
RESUMEN
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.
