目的探讨BBT妇科多功能射频治疗仪(简称自凝刀)治疗巨块型Ⅱb、Ⅲb期宫颈癌的临床价值。方法将Ⅱb、Ⅲb期宫颈癌患者随机分为两组:自凝刀联合放疗组(试验组)与放疗组(对照组)。试验组在放疗前1天,由B超监控用自凝刀将宫颈癌块去除,次日开始放疗。对照组行放射治疗。结果放射性直肠炎的发生率试验组7.5%,对照组22.5%,两组比较差异有显著性(χ2=3.85,P<0.05)。放射性膀胱炎的发生率试验组5%,对照组20%,两组比较差异有显著性(χ2=4.11,P<0.05)。住院时间试验组7～8周,对照组9～10周。住院费用试验组平均每例比对照组少1500元。结论自凝刀联合放疗治疗晚期巨块型宫颈癌,可明显降低放疗并发症,减少医疗费用,缩短住院时间。 Objective To investigate the clinical value of BBT gynecological multifunctional radiofrequency ablation instrument (self coagulation knife) in the treatment of massive type Ⅱb, Ⅲb cervical cancer. Methods Patients with stage Ⅱb and Ⅲb cervical cancer were randomly divided into two groups: self - coagulation knife combined with radiotherapy group (experimental group) and radiotherapy group (control group). One day before radiotherapy, the experimental group was treated with self-coagulation knife to remove the cervical cancer mass by B ultrasound, and radiotherapy was started the next day. Control group radiation therapy. Results The incidence of radiation proctitis was 7.5% in the experimental group and 22.5% in the control group. There was significant difference between the two groups (χ2 = 3.85, P <0.05). The incidence of radiation cystitis was 5% in the test group and 20% in the control group, with significant difference between the two groups (χ2 = 4.11, P <0.05). The duration of hospitalization was 7 to 8 weeks in the experimental group and 9 to 10 weeks in the control group. The average cost of hospitalization test group was 1500 yuan less than the control group. Conclusion Self-coagulation knife combined with radiotherapy for advanced massive cervical cancer can significantly reduce the radiation complications, reduce medical costs and shorten the hospital stay.
