Laparoscopic Radiofrequency Thermal Ablation for Uterine Adenomyosis

Background and Objectives:

Symptomatic uterine adenomyosis, unresponsive to medical therapy, is a challenging condition for patients who desire to preserve their uterus. This study was an evaluation of the feasibility and efficacy of laparoscopic radiofrequency thermal ablation of symptomatic nodular uterine adenomyosis.

Methods:

Fifteen women with symptomatic nodular adenomyosis, who had no plans for pregnancy but declined hysterectomy, underwent radiofrequency thermal ablation. Ultrasonography was performed at baseline and at postoperative follow-ups at 3, 6, 9, and 12 months. The impact of uterine adenomyosis–related symptoms was assessed according to the visual analog scale.

Results:

The median number of nodular lesions treated per patient was 1 (range, 1–2). The median baseline volume of the adenomyosis area was 60 cm³ (range, 18–128). The median reduction in volume was 32, 49.4, 59.6, and 65.4% at 3, 6, 9, and 12 months, respectively. A significant progressive improvement in the symptoms score was observed at the 4 follow-ups.

Conclusion:

In this study, laparoscopic radiofrequency thermal ablation reduced uterine adenomyosis–related symptoms and volume, with significant relief of symptoms.     

肺静脉隔离术后心房颤动早期复发和延迟愈合的相关因素分析

目的探讨Lasso标测导管指导下行节段性肺静脉电隔离术后心房颤动(房颤)早期复发和延迟愈合的相关因素。方法120例[男性104例,女性16例;平均年龄(50．4±8．9)岁]行节段性肺静脉电隔离术的房颤患者,单因素和多因素分析老龄(≥60岁)、性别、房颤类型、病史、合并高血压、左心房直径、射血分数、P波离散度、被隔离肺静脉数及手术时间与早期复发和延迟愈合的相关性。结果早期复发率为48．3％(58／120),左心房扩大(P=0．004)和老龄(P=0．033)与早期复发显著相关,左心房直径是早期复发的独立预测因素(OR=1．16,95％CI为1．04～1．28,P=0．005);延迟愈合率为29．3％(17／58),与延迟愈合显著相关的变量为:P波离散度(P<0.001)、左心房直径(P=0．016)、老龄(P=0．001)。P波离散度是延迟愈合的独立预测因素(OR=0．92,95％CI为0．87-0．97,P=0．005)。结论左心房扩大、老龄与肺静脉隔离术后房颤早期复发有关,左心房直径是早期复发的独立预测因素;P波离散度较小、左心房无扩大的低龄患者延迟愈合的可能性较大,P波离散度是延迟愈合的独立预测因素。     

Symptoms of advanced heart failure—A case for radiofrequency catheter ablation?

A sixty-year-old man with previous history of coronary artery disease was admitted due to progressive worsening of dyspnoea at exertion (NYHA III functional class) and no angina. Coronary angiography confirmed occlusion of the right coronary artery which was naturally bypassed by homocollaterals with TIMI 3 flow to the peripheral branches. The lesion was not technically suitable for percutaneous angioplasty. The left coronary artery was without stenosis. On echocardiography, both the left ventricle and the left atrium were dilated and hemodynamically significant mitral regurgitation was present. Surface ECG showed a left bundle branch block with repeated runs of monomorphic ventricular ectopic beats (PVC). Radiofrequency catheter ablation of the focus in the posteroseptal region of the left ventricle underneath the mitral valve was performed using electroanatomical mapping system. After the procedure, mitral regurgitation decreased and reverse remodeling of the left ventricle and the left atrium occurred with concomitant significant clinical improvement of the patient. The authors discuss several treatment strategies: mitral valve repair surgery combined with revascularization, implantation of a biventricular ICD system or elimination of the focus of monomorphic VT runs by radiofrequency catheter ablation as a possible causal approach in the treatment of PVC-induced cardiomyopathy.     

Alteration of laboratory findings after radiofrequency ablation of hepatocellular carcinoma: relationship to severity of the underlying liver disease and the ablation volume

Background/Aims

To investigate sequential changes in laboratory markers after radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) and the relationship of these changes to the severity of the underlying liver disease.

Methods

This retrospective analysis included 65 patients (44 males, 21 females) who underwent RFA of HCC. Hematologic and biochemical markers were assessed at the pre-RFA period and 1 day, 2-3 days, and 1-2 weeks after RFA. We classified the subjects into two groups: Child-Pugh A (n=41) and Child-Pugh B (n=24). The ablative margin volume (AMV) of each patient was measured. We analyzed the changes in laboratory profiles from the baseline, and investigated whether these laboratory changes were correlated with the AMV and the Child-Pugh classification.

Results

Most of the laboratory values peaked at 2-3 days after RFA. AMV was significantly correlated with changes in WBC count, hemoglobin level, and serum total bilirubin level (Pearson''s correlation coefficient, 0.324-0.453; P<0.05). The alanine aminotransferase (ALT) level varied significantly over time (P=0.023).

Conclusions

Most of the measured laboratory markers changed from baseline, peaking at 2-3 days. The ALT level was the only parameter for which there was a significant difference after RFA between Child-Pugh A and B patients: it increased significantly more in the Child-Pugh A patients.
