改良双腔球囊导管在插管失败的输卵管阻塞介入再通术中的应用价值

目的探讨改良双腔球囊导管在插管失败的输卵管阻塞介入再通术中的应用价值。方法回顾45例输卵管阻塞性不孕患者,应用常规法行介入再通术,其中输卵管开口插管失败采用改良双腔球囊导管行介入再通,统计分析常规法组与联合改良双腔球囊导管法组(联合法组)的输卵管开口插管成功率、输卵管阻塞的开通率。结果输卵管阻塞性不孕患者45例,共阻塞输卵管90条,采用常规法输卵管开口插管成功32条,其中开通成功31条,插管成功率为35.56%,开通率96.88%。采用联合法输卵管开口插管成功90条,输卵管开通83条,插管成功率为100%,开通率92.22%,7条输卵管因阻塞病情严重无法开通,其中双侧均未能开通1例。所有患者术中均无严重并发症发生。随访12个月,妊娠率48.65%。常规法组与联合法组输卵管开口插管成功率差异具有统计学意义(χ^2=85.574,P=0.000),而输卵管开通率差异无统计学意义(χ^2=0.248,P=0.619)。结论对于常规法输卵管开口插管失败者,采用联合改良双腔球囊导管可提高输卵管开口插管成功率。采用改良双腔球囊导管介入再通与常规法开通效果相当,可作为常规介入再通输卵管开口插管失败的备选方案。     

抑郁症患者与不明原因胸痛的关联性探讨

目的:分析抑郁症与不明原因胸痛间的关联性及其可能机制,为临床疾病的治疗提供参考依据。方法:纳入2012年6月至2014年5月四川省南充精神卫生中心精神科收治的不明原因胸痛患者35例,作为观察组,另选取35例来院进行常规体检的健康志愿者作为对照组,比较两组的抑郁量表评分、抑郁症发生率、血清C反应蛋白(CRP)、白细胞介素6(IL-6)、五羟色胺(5-HT)及外周血中的CD4+、CD8+含量。结果:与对照组比较,观察组的CRP、IL-6、5-HT、CD4+均低于对照组;且观察组的CD8+、抑郁症发生率(31.43%)、轻中度抑郁及重度抑郁患者比例均高于对照组水平,组间对比差异显著(P<0.05)。结论:抑郁症与不明原因胸痛存在一定相关性,推断可能与CRP、5-HT、IL-6等细胞因子有关,也可能与免疫抑制过程有关,在临床诊治中需引起重视。     

Perfusion pressure flow study in the upper urinary tract

Hydronephrosis with an undetermined pathology is a common condition detected in imaging studies. In urological clinical practice, it is a persistent dilemma to predict whether this condition will progress to result in the deterioration of renal function. Perfusion pressure flow study of the upper urinary tract, known as the Whitaker test, provides an alternative diagnostic tool for solving this condition. Perfusion pressure flow study has been criticized for its invasiveness, nonphysiological approach, and inconsistency in predicting outcomes. However, it continues to be used to evaluate difficult or equivocal cases and to provide an objective assessment of the upper urinary tract.     

Dynamic LVOT Obstruction and Aortic Stenosis in the Same Patient: A Case of Challenging Doppler Hemodynamics

We present a patient with both dynamic left ventricular outflow tract obstruction and valvular aortic stenosis. The aortic valve was calcified, and velocities and gradients measured by continuous‐wave Doppler met standard criteria for severe aortic stenosis. The increased subvalvular velocities invalidated assumptions of the simplified Bernoulli equation; correction using the longer form of the Bernoulli equation suggested a lower but still significant gradient. The complex shape of the subvalvular spectral Doppler envelope indicated supranormal systolic function and dynamic left ventricular outflow obstruction. Left heart catheterization with an end‐hole catheter was required to determine the subvalvular and valvular components of the obstruction.     

Intervention for arch obstruction after the Norwood procedure: Prevalence,associated factors,and practice variability

Objective

Arch obstruction after the Norwood procedure is common and contributes to mortality. We determined the prevalence, associated factors, and practice variability of arch reintervention and assessed whether arch reintervention is associated with mortality.

Cardiac-type total anomalous pulmonary venous return is not benign

ObjectiveThe objective of this study was to investigate the association between morphological variation and postsurgical pulmonary vein (PV) stenosis (PPVS) in patients with cardiac total anomalous pulmonary venous connection (TAPVC).MethodsThis single-center, retrospective study included 168 pediatric patients who underwent surgical repair of cardiac TAPVC from 2013 to 2019 (connection to the coronary sinus [CS], n = 136; connection directly to the right atrium [RA], n = 32). Three-dimensional computed tomography modeling and geometric analysis were performed to investigate the morphological features; their relevance to the PPVS was examined.ResultsThe connection type had no association with PPVS (CS type: 18% vs right atrial type: 19%; P = .89) but there was a higher incidence of PPVS in patients with a single PV orifice than > 1 orifice (P < .001). Confluence-to-total PV area ratio (hazard ratio, 4.78, 95% CI, 1.86-12.32; P = .001) and length of drainage route (hazard ratio, 1.22; 95% CI, 1.14-1.31; P < .001) had a 4- and 1-fold increase in the risk for PPVS in the CS type after adjustment for age and preoperative pulmonary venous obstruction. In the right atrial type, those with anomalous PV return to the RA roof were more likely to develop PPVS than to the posterior wall of the RA (P < .001).ConclusionsThe number of inter-junction PV orifice correlated with PPVS development in cardiac TAPVC. The confluence-to-total PV ratio, length of drainage route, and anomalous PV return to the RA roof are important predictors for PPVS. Morphological subcategorization in this clinical setting can potentially assist in surgical decision-making.     

Risk factors and management of stoma-related obstruction after laparoscopic colorectal surgery with diverting ileostomy

BackgroundStoma-related obstruction (SRO) is defined as small bowel obstruction occurring around the limbs of diverting ileostomy (DI). This study was aimed to investigate the incidence, risk factors, and management of SRO after laparoscopic colorectal surgery with DI creation.MethodsThis study included 155 patients who underwent laparoscopic colorectal surgery with DI creation for rectal cancer (n = 138), ulcerative colitis (UC) (n = 14), and familial adenomatous polyposis (FAP) (n = 3) between 2011 and 2019. Univariate and multivariate analyses were performed to identify the risk factors of SRO.ResultsThe incidence of SRO was 7.7% (n = 12), and it was significantly lower (P < 0.01) in patients with lower anterior resection or intersphincteric resection (4.3%) than in those with ileal-pouch anal anastomosis (IPAA) (35.2%). The multivariate analysis revealed that IPAA was independently associated with the development of SRO (P = 0.001; odds ratio, 9.4; 95% confidence interval, 2.5–35.4). Eleven of 12 patients (92%) with SRO required trans-stomal tube decompression, and 8 of those (67%) underwent early stoma closure.ConclusionIPAA was an independent risk factor of SRO in laparoscopic colorectal surgery with DI creation. Early stoma closure was needed in most cases of SRO.
