Laparoscopic versus open pancreatoduodenectomy: an individual participant data meta-analysis of randomized controlled trials

BackgroundRandomized trials have compared laparoscopic pancreatoduodenectomy (LPD) to open pancreatoduodenectomy (OPD) with conflicting results. An IPDMA may give more insight into the differences between LPD and OPD, and could identify high-risk subgroups.MethodsA systematic literature search was performed in the Pubmed, Embase, and the Cochrane library databases (October 2019). Out of 1410 studies, three randomized trials were identified. Primary outcome was major complications (Clavien-Dindo grade ≥ III). Subgroup analyses were performed for high-risk subgroups including patients with BMI of ≥25 kg/m2, pancreatic duct <3 mm, age ≥70 years, and malignancy.ResultsData from 224 patients were collected. After LPD, major complications occurred in 33/114 (29%) patients compared to 34/110 (31%) patients after OPD (adjusted odds ratio (OR) 0.62; 95% confidence interval (CI) 0.3–1.4, P = 0.257). No differences were seen for major complications and 90-day mortality LPD 8 (7%) vs OPD 4 (4%) (adjusted OR 0.2; 95% CI 0.02–1.3, P = 0.080). With LPD, operative time was longer (420 vs 318 min, p < 0.001) and hospital stay was shorter (mean difference ?6.97 days). Outcomes remained stable in the high-risk subgroups.ConclusionLPD did not reduce the rate of major postoperative complications as compared to OPD. LPD increased operative time and shortened hospital stay with 7 days.     

不完全射频消融对兔VX2肝癌MMP-9表达的影响

目的研究不完全射频消融（RFA）治疗对兔VX2肝癌模MMP-9蛋白表达的影响。 方法建立新西兰白兔的VX2肝癌模型,将30只兔VX2肝癌模型分为2组,即对照组和实验组,每组15只,对照组只做开关腹,而不进行RFA;实验组进行开腹消融,消融范围为肿瘤组织的75%;在实验组中设立RFA后快速进展亚组,定义为实验结束时肿瘤的倍增率大于对照组。对比其RFA后的VX2肝癌的体积变化、残留VX2肝癌基质金属蛋白酶-9（MMP-9）的表达情况。 结果对照组和实验组治疗后肿瘤体积分别为（7 862±1 304）mm³和（6 996±709）mm³,肿瘤的倍增率分别为（291±49）和（232±16）,差异有统计学意义（P < 0.05）。对照组和实验组MMP-9阳性表达率为52.1%和46.3%,差异均有统计学意义（P < 0.05）;实验组中3只实验兔肿瘤倍增率及MMP-9表达率明显高于实验组,属于RF后快速进展亚组,差异有统计学意义（P < 0.05）。 结论部分性消融对大多数肝细胞癌具有一定疗效,但对于少数肿瘤可能加速其生长,而MMP-9的过表达可能是促进残留癌快速进展的原因。     

早期糖尿病肾病预测指标及危险因素研究

目的探讨糖耐量减低（IGT）患者早期糖尿病肾病的预测指标、患病率及影响因素。方法262例受试者中正常糖耐量（NGT）103人、IGT98人、糖尿病（DM）61人，全部进行即刻尿转铁蛋白／肌酐（UTRF／Cr）和尿白蛋白／肌酐（UAlb／Cr）的检测及临床观察指标的测定。结果（1）UTRF／Cr与UAlb／Cr呈显著正相关，r=0．618，P＜0.001。（2）IGT组的UAlb／Cr（中位数，极差）、UTRF／Cr（中位数，极差）高于NGT组（0．015，0．44mg／mg比0.012，0．58mg／mg，t=-1.981，P=0．049；0.064，4.96mg／mg比0.034，7.30mg／mg，t=-2．249，P=0．026）。（3）各组UTRF／Cr比值的阳性率明显高于白蛋白尿的阳性率（41．6％比29．7％，P（0．01）。（4）Logistic回归分析显示白蛋白尿的主要危险因素是DBP，OR=1．064，2hPGOR=1．109，P＜0.01；非糖尿病组的主要危险因素是DBP，OR=1．064，P＜0.01。结论在IGT阶段已存在早期糖尿病肾脏损害，高血压是其重要的危险因素。尿转铁蛋白／肌酐比值的检测较白蛋白尿／肌酐比值更灵敏，但仍需进一步综合比较二者的敏感性和特异性。     

Real-time screening tool for identifying post-traumatic stress disorder in facial trauma patients in a UK maxillofacial trauma clinic

Post-traumatic stress disorder (PTSD) is a distressing consequence of a traumatic event associated with an increased suicide risk and reduced quality of life. Surgeons often have low confidence in identifying psychological problems. The prevalence of PTSD following facial trauma ranges from 23% to 41%. This highlights the importance of identifying and managing at-risk patients to optimize both mental and physical recovery. IMPARTS (Integrating Mental and Physical healthcare: Research, Training and Services) provides electronic screening tools to guide the non-mental health clinician in the ‘real-time’ identification, documentation, and management of potential mental health problems. The bespoke IMPARTS facial trauma screening tool was piloted in a UK oral and maxillofacial surgery trauma clinic from July 2015 to November 2017. A total of 199 patients completed screening, with 48 (24%) screening positive for possible PTSD. Further analysis of these 48 patients revealed that four (8%) had PTSD symptoms alone; three (6%) also screened positive for depression, 17 (35%) for co-existing symptoms of anxiety, and 24 (50%) for PTSD, anxiety, and depression. IMPARTS was found to be a highly effective tool aiding the non-mental health clinician to screen for PTSD and initiate prompt management. The data captured informs planning of the psychological support service.     

经胸与经食管超声心动图在先天性心脏病介入治疗中的应用

导管室介入封堵及外科小切口介入封堵都已经被广泛地应用于临床,封堵成功的关键在于经胸与经食管超声心动图在术前对病例精确的筛选、术中监测及术后即刻评价。文章结合目前国内外文献及临床病例,对经胸与经食管超声心动图在房间隔缺损、室间隔缺损和动脉导管未闭3种常见先天性心脏病介入治疗中的应用进行综述,为临床提供更加准确的超声影像学诊断依据。     

99mTc-3PRGD2 SPECT/CT显像用于肺部肿瘤分期及疗效评估的研究进展

近年来,肺癌发病率逐年上升,也是恶性肿瘤中致死率排名第1位的疾病,晚期患者生存率极低。血管生成和淋巴结转移是恶性肿瘤的两个非常重要的特征,通常认为整合素αvβ3的表达与这两个特征均有关。放射性核素标记的精氨酸-甘氨酸-天冬氨酸肽能与整合素特异的结合,进而可以反映肿瘤血管的变化。达到对肺癌原发灶、转移灶及疗效的早期监测,本文对近年来国内外99mTc-3PRGD2 SPECT/CT用于肺部肿瘤诊断的研究进展进行综述,主要从99mTc-3PRGD2显像剂、9mTc-3PRGD2在肺癌原发灶显像方面、99mTc-3PRGD2 SPECT显像对非小细胞肺癌淋巴结转移监测、99mTc-3PRGD2 SPECT成像在肺癌患者远处转移的诊断、99mTc-3PRGD2 SPECT成像在肺癌患者化疗、靶向药物疗效评估等几个方面展开论述。      

基于腰椎间盘突出应用MRI与CT诊断的临床特异性比较

目的:探究在腰椎间盘突出诊断中MRI与CT的特异性及准确度。方法:由本院2019年11月—2020年10月期间内就诊群体,随机选择60例患者作为对比研究对象,对60例患者分别通过MRI与CT进行检查,以手术病理结果作为诊断金标准,对比两种诊断手段对60例患者的结果准确性,同时对比两种诊断手段的征象。结果:60例患者均经手术病理诊断为腰椎间盘突出症,MRI确诊57例患者,诊断准确率为95%,CT确诊49例患者,诊断准确率为81.67%,组间比较有明显差异;CT对钙化、积气的征象诊出率明显高于MRI,MRI对椎间盘变性、硬膜囊受压、脊髓变性征象的检出率明显高于CT,两者在神经根受压的检出率不存在差异性。结论:相较CT,MRI对腰椎间盘突出的诊断准确性更高,但CT也有其应用价值,对钙化和积气的检出率更高,因此临床上可根据实际情况进行选择,必要时可联合应用。
