盆筋膜解剖及其与直肠固有筋膜关系研究

目的 探讨盆筋膜的结构、范围及其与直肠固有筋膜的层次关系。方法 2020年12月至2021年3月对由广东药科大学生命与生物制药学院人体解剖与胚胎学系及中山大学中山医学院人体解剖学教研室提供的12具（男性5具、女性7具）骨盆标本进行大体观察，并对Denonvilliers筋膜进行组织学观察。结合2019年12月至2021年3月中山大学附属第三医院胃肠外科收治的20例直肠癌病人（男性10例、女性10例）的盆腔磁共振图像和手术视频进行解剖学印证。结果 12具骨盆大体标本显示，盆筋膜与Gerota筋膜相延续，部分纤维于S4水平构成直肠骶骨筋膜，向下与直肠固有筋膜融合终止于联合纵肌；部分纤维与后方骶前筋膜融合构成肛提肌上筋膜及肌间纤维。Denonvilliers筋膜在盆腔前外侧约2点、10点处与盆筋膜相延续构成完整筒状结构，包绕内层由直肠固有筋膜封套的直肠系膜；除“侧韧带”处有盆腔自主神经直肠支、淋巴管、直肠中动脉相连外，两层筋膜形成完整的双筒状结构，横断面呈同心圆状。除直肠支进入直肠固有筋膜外，盆腔自主神经主要分支均位于盆筋膜内层及Denonvilliers筋膜以外，沿直肠固有筋膜轮廓游离能够避免损伤盆腔自主神经。在7具女性骨盆标本中均能见到菲薄的Denonvilliers筋膜结构。直肠癌病人的横断面磁共振图像能够看到直肠固有筋膜与外侧盆筋膜、Denonvilliers筋膜的轮廓和间隙，手术视频资料也可见到完整盆壁筋膜和Denonvilliers筋膜的轮廓。结论 直肠癌手术中，在盆筋膜、Denonvilliers筋膜与直肠固有筋膜两层结构的间隙进行分离，并保持两层筋膜的完整性，对于保证肿瘤根治性和保护排尿及性功能至关重要。     

Oncologic benefit of adjuvant chemotherapy for locally advanced rectal cancer after neoadjuvant chemoradiotherapy and curative surgery with selective lateral pelvic lymph node dissection: An international retrospective cohort study

IntroductionIntensive local treatment comprising total mesorectal excision (TME) with selective lateral pelvic lymph node dissection (LPND) after neoadjuvant chemoradiotherapy (CRT) for locally advanced rectal cancer (LARC) has received attention among clinicians treating rectal cancer. It remains unclear whether adjuvant chemotherapy (ACT) after intensive local treatment is beneficial for these patients. We evaluated the oncologic benefit of ACT for patients with LARC who received intensive local treatment.Materials and methodsThis international multicentre retrospective cohort study included 737 patients treated in Japan and Korea between 2010 and 2017. The effectiveness of ACT on recurrence-free survival (RFS) was evaluated using univariable and multivariable Cox proportional hazards models, with subgroup analyses to identify subpopulations potentially benefiting from ACT.ResultsThe median follow-up was 49 months; the 5-year RFS and local recurrence rates for the entire cohort were 72.1% and 4.9%, respectively; 514 patients (69.7%) received adjuvant chemotherapy, without an oncologic benefit (hazard ratio, 1.14; 95% confidence interval [CI]: 0.79–1.68) demonstrated in the multivariable Cox regression analysis. In subgroup analyses, the distributions of the 95% CI in patients aged ≥70 years and those with ypStage 0 tended to place a disproportionate emphasis that favoured the non-ACT treatment strategy.ConclusionDespite achieving good local control with intensive local treatment strategy, the effectiveness of ACT for the LARC patients with CRT followed by TME with selective LPND was not proved. Elderly patients and those with ypStage0 may not receive benefit from ACT after CRT and TME ± LPND.

目的探讨集束化护理干预对前列腺癌患者术后盆底功能锻炼依从性及尿失禁的影响。方法选取2020年1月至2020年12月间上海中医药大学附属曙光医院收治的50例前列腺癌根治术患者作为研究对象。其中,围手术期采用常规护理的20例患者纳入对照组。围手术期采用集束化护理的30例患者纳入观察组。比较两组术后盆底功能锻炼的依从性及尿失禁情况。结果观察组拔管后1个月、3个月盆底功能锻炼的依从性分别为76.7%和70.0%,均高于对照组的45.0%和35.0%,差异均有统计学意义(均P <0.05)。观察组拔管后1个月、3个月的尿失禁发生率分别为10.0%和6.7%,低于对照组的40.0%和35.0%,差异均有统计学意义(均P <0.05)。观察组尿失禁持续时间为(3.83±0.95)天,短于对照组的(5.38±1.97)天,观察组拔管后3个月尿失禁问卷评分低于对照组,差异均有统计学意义(均P <0.05)。结论集束化护理干预能够提高前列腺癌患者术后盆底功能锻炼的依从性,预防术后尿失禁的发生。     

3D打印骨折模型在复杂骨盆骨折手术中的治疗方法及效果探讨

目的:探讨复杂骨盆骨折手术治疗中3D打印骨折模型的应用方法及效果。方法:选取医院收治的60例复杂骨盆骨折患者,按照随机数表法将其分为对照组和观察组,每组30例。对照组行传统CT指导下手术治疗,观察组行3D打印仿真骨盆模型体外模拟术后,应用腹直肌旁切口钢板内固定术治疗。比较两组手术时间、住院时间和骨折愈合时间,以及术中出血量、并发症发生率和骨盆功能恢复优良率。结果:观察组手术时间、住院时间及骨折愈合时间短于对照组,术中出血量少于对照组,差异有统计学意义(t=2.721,t=2.458,t=2.791,t=4.450;P<0.05);观察组和对照组并发症发生率分别为3.33%和10.00%,差异无统计学意义(x²=0.267,P>0.05);观察组和对照组骨盆功能恢复优良率分别为96.67%和73.33%,观察组明显高于对照组,差异有统计学意义(x²=4.705,P<0.05)。结论:复杂骨盆骨折手术中应用3D打印骨折模型可缩短手术时间、住院时间,减少出血量,促进骨折愈合,可改善骨盆功能且并发症少。     

Measuring healthy female nulliparous pubovisceral muscle from diffusion kurtosis imaging

This study explores the feasibility of using diffusion kurtosis imaging (DKI) in the pelvic floor region and assesses the water diffusivity of the pubovisceral muscle. Twenty-seven healthy young nulliparous females underwent DKI at 3.0 T that included 15 gradient directions and three b values (0, 750, and 1500 s/mm²). The diffusion tensor and diffusion kurtosis metrics values of the pubovisceral muscle were measured after image processing. Two independent sample t-tests, a paired-samples t-test, and a nonparametric hypothesis test were performed as appropriate to compare the differences among different metrics. Twenty-six subjects (mean ± standard deviation age, 25 ± 2 years) were successfully analyzed by measuring the diffusion tensor and diffusion kurtosis metrics of the bilateral pubovisceral muscles. The metrics included mean kurtosis, axial kurtosis, radial kurtosis, fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity. We found no statistically significant differences for these measurement values between the left and right pubovisceral muscles (p = 0.271–0.931). However, radial kurtosis was greater than axial kurtosis in both pubovisceral muscles (p < 0.001) and axial diffusivity was lower than radial diffusivity in both pubovisceral muscles (p < 0.001). We deem the application of DKI technology to the pelvic floor region to be feasible.

目的探讨产后瑜伽锻炼对阴道分娩产妇体型及盆底肌张力恢复的影响。方法选取2019年8月-2020年8月我科行自然分娩的产妇480例为研究对象,采用随机数字表法分为观察组和对照组,各240例。对照组产后行常规康复指导,观察组在对照组的基础上行瑜伽锻炼。比较两组干预前后产妇产后体型恢复、心理健康状况及盆底肌张力恢复情况。结果观察组干预后3个月焦虑自评量表(SAS)评分、爱丁堡产后抑郁量表(EPDS)评分显著低于对照组(P<0.05)。观察组干预后3个月腰围、臀围、腹部皮皱、体质量指数优于对照组(P<0.05)。观察组干预后3个月Ⅰ类、Ⅱ类纤维肌力评分显著高于对照组(P<0.05)。结论产后瑜伽锻炼有助于促进阴道分娩产妇体型及盆底肌张力恢复,减轻产妇产后焦虑、抑郁情绪,有助于产妇身心健康。     

Uso de inhibidores de la aromatasa en el tratamiento del dolor pélvico asociado a endometriosis: revisión sistemática

ObjectiveTo know the effect of the use of aromatase inhibitors (AI) in the treatment of endometriosis-associated pelvic pain (EAPP).Material and methodsSystematic review of the literature.Results173 articles were identified of which 25 were valid for the review, of which 4 were randomized clinical trials, 3 were non-randomized clinical trials, 10 were prospective non-comparative studies and 8 were clinical case reports. In most of the studies and/or case reports (24 of 27) the use of AI was associated with an improvement in EAPP. Important biases were identified that may influence the efficacy analysis, primarily the combined use of AI with other drugs widely used in the treatment of endometriosis.ConclusionsDespite the existence of numerous articles presenting and/or analysing the effect of AIs in the control of EEAP, the biases in the interpretation of their results, together with the side effect profile of this group of drugs, mean that their use has not become widespread, and they continue to be considered an experimental treatment for endometriosis. To date, there is insufficient evidence of sufficient quality to recommend the use of AI in the treatment of EEAP in routine clinical practice.
