目的:探讨影响宫颈环状电切术(loop electrosurgical excision procedure,LEEP)治疗宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)的预后因素。方法:2011年8月至2013年12月选择在我院进行诊治的宫颈上皮内瘤变患者170例,都给予LEEP治疗,观察术后疗效及其不良反应发生情况。结果:所有患者都完成LEEP术,有效率为94.7%;发生不良反应14例,发生率为8.2%,都经过对症处理后好转。Logistic回归模型进行分析结果显示年龄、CIN分级、宫颈糜烂状况是影响宫颈上皮内瘤变预后的主要独立危险因素(P<0.05)。结论:LEEP治疗宫颈上皮内瘤变具有很好的预后疗效,不良反应较少,影响其预后的因素主要为年龄、疾病分级与宫颈糜烂状况。     

Small renal mass management in the elderly and the calibration of risk

Due to the increased utilization of cross-sectional imaging and prolonged life expectancy, the incidence of incidentally diagnosed renal tumors continues to rise. While partial nephrectomy is currently recommended as the gold standard treatment of cT1a small renal mass whenever technically feasible, the perceived benefits of partial nephrectomy may not be applicable to all patient groups. Selecting between treatment options in elderly and the infirm can present a significant challenge. Informed and thoughtful small renal mass management decisions require consideration and balance of patient, tumor, and procedural risks to maintain oncological efficacy while minimizing treatment associated morbidity. Herein we review the comparative effectiveness of partial versus radical nephrectomy in the elderly and the role of standardized tools to quantify risk.     

Clinical impact of left atrial appendage resection versus preservation during surgical ablation of atrial fibrillation

IntroductionResection of left atrial appendage (LAA) during surgical ablation of atrial fibrillation may decrease the incidence of postoperative cerebrovascular events and increase the induction and maintenance of sinus rhythm (SR). This study evaluates the effect of LAA resection after the surgical ablation of atrial fibrillation.Materials and methodsA retrospective analysis was made of 599 patients who underwent surgical myocardial revascularization and/or valve surgery with concomitant surgical ablation of atrial fibrillation. The LAA was resected in 140 patients and preserved in 459 patients. Postoperative, 1-month and 1-year results were compared between the groups in terms of TIA/CVA, maintenance of sinus rhythm, pacemaker dependence and mortality.ResultsThe patients who underwent LAA resection were older, had more frequent persistent AF and underwent more frequently biatrial ablation set. In this group, longer times of extracorporeal circulation and longer cross-clamp times were observed. During the follow-up period, the resection group has shown lower incidence of TIA/CVA and the overall mortality was also lower in this group of patients.ConclusionThe resection group in our study has shown the trend toward lower incidence of TIA/CVA and statistically significant decrease of overall mortality. This finding can support routine LAA resection during surgical ablation of atrial fibrillation.     

竖脊肌平面阻滞超前镇痛对老年胸腔镜肺癌根治术患者心肌的保护作用

目的探讨竖脊肌平面阻滞（ESPB）超前镇痛对老年胸腔镜肺癌根治术患者心肌的保护作用。 方法选择在惠州市中心人民医院择期行胸腔镜肺癌根治术的老年患者40例，按照患者意愿分组，其中19例采用ESPB联合全身麻醉（观察组），21例采用单纯全身麻醉（对照组）。在两组诱导前（T0）、手术开始1 h（T1）、手术结束时（T2）及术后4 h（T3）检测患者的肌钙蛋白Ⅰ（cTnⅠ）、心型脂肪酸结合蛋白（H-FABP）、肌酸激酶同工酶（CK-MB），并记录各时间点的平均动脉压（MAP）和心率。计量资料的组间比较采用t检验，重复测量资料采用重复测量方差分析。 结果两组患者MAP、心率、cTnⅠ、H-FABP、CK-MB的差异均呈现组间效应、时间效应和交互效应（MAP：F=24.021、33.512、9.184，心率：F=10.340、46.992、3.494，cTnⅠ：F=5.354、691.994、64.177，H-FABP：F=7.906、14.067、11.560，CK-MB：F=15.926、84.106、4.116，P<0.05或0.01）。与T0时间点比较，两组患者T1、T2、T3时间点MAP、心率、H-FABP、CK-MB均出现明显变化（P<0.05），T2、T3时间点cTnⅠ出现明显变化（P<0.05）。 结论老年胸腔镜肺癌根治术中应用ESPB超前镇痛，可明显降低心肌损伤相关因子水平，起到心肌保护作用。

Comparison of Gap Balancing vs Measured Resection Technique in Patients Undergoing Simultaneous Bilateral Total Knee Arthroplasty: One Technique per Knee

BackgroundTotal knee arthroplasty requires careful surgical technique to attain the goal of a well-aligned and symmetrically balanced knee. Soft tissue balance and correct femoral component rotation are paramount in achieving these goals. The two competing techniques to select femoral component rotation and soft tissue balance are the gap balance technique and the measured resection technique.MethodsWe performed a randomized, prospective study to compare the two techniques in patients undergoing simultaneous bilateral total knee arthroplasty, whereby one technique was performed in each knee. Fifty (50) subjects were enrolled into the study. The inclusion criteria were osteoarthritic varus knee deformities with similar deformities in both knees. Subjects were followed up for a minimum of two years.ResultsThe knees balanced via the gap balance technique had significantly more posterior medial bone removed from the femur than those knees balanced via the measured resection technique (P < .001). Knees in the gap balance group tended to require more medial knee releases in extension and tended to have smaller sized femoral components as a result of cutting more bone from the femur in flexion. The modular tibial polyethylene bearing tended to be thicker in the gap balance group. Despite these differences, average knee flexion and functional revised Oxford Knee Scores at 2-year follow-up were not statistically different.ConclusionAt 2-year follow-up, there were no differences between the function and scores using the two techniques. Long-term follow-up will be necessary to evaluate any differences in long-term durability.     

Laparoscopic anatomic segmentectomy 8 using the outer-Laennec approach

BackgroundLaparoscopic anatomic segmentectomy 8 is a difficult and technically demanding procedure owing to exposure of two major hepatic veins. To safely and accurately perform this procedure, the outer-Laennec approach was developed (Kiguchi et al., 2019) [1], which is based on the structure of Laennec's capsule (Sugioka et al., 2017; Laennec, 1802; Hayashi et al., 2008) [2,3,4]. The capsule comprises two layers: the hepatic and cardiac Laennec's capsules surrounding the major hepatic vein (Kiguchi et al., 2019) [1]. The outer-Laennec approach maintains the strength of the hepatic vein wall, preserving the two layers of Laennec's capsule. We describe a laparoscopic anatomic segmentectomy 8 using the outer-Laennec approach for hepatocellular carcinoma (HCC).MethodsParenchymal transection was initiated to expose the root of the middle hepatic vein and right hepatic vein with the cranio-caudal view. The space between the hepatic Laennec's capsule and liver parenchyma was invaded using the outer-Laennec approach. The cavitron ultrasonic surgical aspirator was used from the root side toward the peripheral side to retain the hepatic Laennec's capsule on the vein wall and avoid splitting the bifurcation of the hepatic vein. The parenchymal dissection process was completed by an S8 Glissonean pedicle dissection.ResultsThe operative time was 296 min, and the estimated blood loss was 10 mL. The postoperative course was uneventful, and the patient was discharged on postoperative day 5. A pathological examination confirmed that the 2.0-cm mass was HCC with negative margins.ConclusionThe outer-Laennec approach is feasible and useful to standardize the safe laparoscopic anatomic segmentectomy 8.
