Argon gas embolism in the application of laparoscopic microwave coagulation therapy

Background  A major concern in the use of the argon beam coagulator system is the potential risk of argon gas embolism. Methods  Seven cases with argon gas embolism in the English literature were reviewed along with the current case. The latter case was a 77-year-old female having laparoscopic hepatectomy after application of the microwave coagulation system on the cutting planes. Results  Immediately following shots of an argon beam to control local bleeding at the needle hole in the liver caused by microwave coagulation, the end-tidal carbon disappeared, followed by cardiovascular collapse. After 18 min of cardiovascular resuscitation, the tumors were resected under laparotomy. Conclusions   After reviewing the cases, pneumoperitoneum (57.1%), hepatic needle punctures (42.8%) and direct application of the argon beam to the liver (28.6%) can be considered as risky processes in such events. Caution is necessary in the use of an argon beam in liver surgery to avoid life-threatening gas embolism.     

重组人干扰素α-2b阴道泡腾胶囊联合微波治疗宫颈糜烂的临床分析

目的：探讨重组人干扰素α-2b阴道泡腾胶囊治疗宫颈糜烂的临床疗效。方法：选择年龄在20-48岁的宫颈糜烂患者273例．按宫颈糜烂面积及程度分类,用重组人干扰素α-2b阴道泡腾胶囊联合微波治疗与单纯微波治疗进行对照观察。结果：观察组213例患者中,轻度宫颈糜烂治愈率为97．0％,中度宫颈糜烂治愈率为96．5％,重度宫颈糜烂治愈率74．2％,总有效率达89．7％,仅1013％患者无效。结论：重组人干扰素α-2b阴道泡腾胶囊具有抗病毒作用,治疗宫颈糜烂有显著疗效,对预防宫颈癌起到了积极作用,值得临床推广使用。     

慢性盆腔炎综合治疗临床疗效分析

目的：观察中西药及微波综合治疗慢性盆腔炎的疗效。方法：142例慢性盆腔炎患者,随机分为对照组和治疗组,每组各71例。对照组采用经期第一天开始生理盐水250 mL＋菌必治4.0 g静脉滴注,1次/d;0.5%甲硝唑（或替硝唑）100 mL,静脉滴注,2次/d,7 d为1个疗程,连续治疗3个月经周期;治疗组除采用对照组的治疗外,月经干净3 d后再加上金刚藤糖浆口服及微波同时治疗。金刚藤糖浆20 ml口服,3次/d,连续服用25 d为1个疗程。微波采用园形探头照射盆腹腔30 min,1次/d,连续照射15 d为1个疗程。两组均以治疗3个疗程后判断疗效,比较两组患者治疗后的临床效果。结果：治疗组的总有效率明显高于对照组,差异有显著性（P〈0.05）。结论：中西药及微波综合疗法治疗慢性盆腔炎效果显著。     

Preliminary clinical experiences of a motorized manipulator for magnetic resonance image–guided microwave coagulation therapy of liver tumors

Background

In magnetic resonance (MR) image-guided microwave thermocoagulation of liver tumors, the choice of the optimal puncture route is an important and time-consuming process. To assist this process, we have developed a motorized MR-compatible manipulator.

Methods

The manipulator consists of a passive end effecter with 2 degrees-of-freedom (DOF) rotation and active base stages with 3 ultrasonic motors. It automatically chases the preset target point with synergetic remote-center-of-motion (RCM) control. A mechanical torque limiter and an electrical shutdown switch were added for patient safety.

Results

The manipulator was used for this procedure in 15 cases and successfully utilized to treat liver tumors in various locations. Thoracoscopic assistance was combined with the manipulator in 6 cases. No complications were experienced.

Conclusions

The manipulator was found to be very effective for assisting MR-guided microwave coagulation of liver tumors.
