Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery: Diagnoses and Surgical Results in 12 Pediatric Patients

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital condition. It responds well to early diagnosis and treatment, but otherwise the prognosis is poor. We present our case series of 12 patients (mean age, 2 ± 2.58 yr; age range, 2 mo–8 yr), emphasizing the diagnostic process and discussing our surgical results. The diagnosis of ALCAPA should be suspected in infants who have dilated cardiomyopathy with electrocardiographic changes that suggest ischemia, and in older children who have isolated mitral regurgitation. When clinical suspicion is high, the results of 2-dimensional echocardiography combined with color-flow Doppler studies in expert hands can establish the diagnosis, thus avoiding angiography in critically ill infants. The treatment of choice in our patients was transfer and reimplantation of the left coronary artery onto the ascending aorta. There were 2 deaths: both were infants in extremis who underwent emergency surgery. An older child with severe ventricular dysfunction was given mechanical ventricular assistance and then heart transplantation. As of this report, all 10 survivors remained well and asymptomatic.     

Outpatient Hysterectomy versus Inpatient Hysterectomy: A Systematic Review and Meta-analysis

ObjectiveThe aim was to investigate whether outpatient hysterectomy (OH) has benefits when compared with inpatient hysterectomy (IH) regarding postoperative complications, readmissions, operative outcomes, cost, and patient quality of life.Data SourcesA systematic search for studies comparing OH with IH was conducted through PubMed, SAGE, and Scopus from January 2010 to March 2020, without limitations regarding language and study design.Methods of Study SelectionStudies reporting on the differences between same-day discharge and overnight stay after hysterectomy were included. The study outcomes were overall complication rate, type of complication, readmission after discharge, surgery duration, estimated blood loss, payer savings, hospital savings, and health-related quality of life (HrQoL). Median and range are used to describe non-normal data, while mean ± SD and confidence interval are used to descibe data with normal distribution. A meta-analysis with sensitivity analysis and subgroup analyses was performed.Tabulation, Integration, and ResultsEight studies published between 2011 and 2019 with 104,466 patients who underwent hysterectomy were included in this systematic review and meta-analysis. All included studies except 1 were found to have a high risk of bias. OH in comparison with IH had a lower overall complication rate (odds ratio [OR] 0.70; 95% confidence interval [CI], 0.60–0.82) and lower rates of wound infection (OR 0.60; 95% CI, 0.43–0.84), urinary tract infection (OR 0.64; 95% CI, 0.52–0.78), need for transfusion (OR 0.36; 95% CI, 0.22–0.59), sepsis (OR 0.33; 95% CI, 0.17–0.64), uncontrolled pain (OR 0.79; 95% CI, 0.66–0.95), and bleeding requiring medical attention (OR 0.82; 95% CI, 0.73–0.94). In addition, patients who underwent OH had a lower readmission rate (OR 0.81; 95% CI, 0.75–0.87), surgery duration (standardized mean difference –0.35; 95% CI, –0.61 to –0.08), and estimated blood loss (standardized mean difference –0.63; 95% CI, –0.93 to –0.33) than those who underwent IH. A qualitative analysis found that OH had a poorer patient HrQoL and a lower cost for the hospital as well as the payer.ConclusionOHs present fewer complications and have a lower readmission rate and estimated blood loss as well as a shorter surgery duration than IHs. OHs also have a cost benefit in comparison with IHs. But patients seem to have a worse HrQoL in the first postoperative week after OH. The high risk of bias of the included studies indicates that well-designed clinical trials and standardization of surgical complication reporting are essential to better address this issue.     

不同手术方法治疗复杂胫骨平台骨折临床疗效观察

目的探讨不同手术方法治疗复杂胫骨平台骨折临床疗效。方法选择2016年1月—2018年12月84例复杂胫骨平台骨折患者,随机分组。单侧锁定钢板内固定组选择单侧锁定钢板内固定手术,双侧切口双侧解剖钢板内固定组选择双侧切口双侧解剖钢板内固定。分析手术操作时间、手术失血、平均住院天数以及复杂胫骨平台骨折愈合时间;治疗前后患者视觉模拟评分和Rasmussen膝关节功能评分;膝关节僵硬发生率。结果双侧切口双侧解剖钢板内固定组视觉模拟评分和Rasmussen膝关节功能评分、手术操作时间、手术失血、平均住院天数以及复杂胫骨平台骨折愈合时间、膝关节僵硬发生率和单侧锁定钢板内固定组比较有优势,P<0.05。结论复杂胫骨平台骨折患者实施双侧切口双侧解剖钢板内固定可获得较好效果。     

Successful Use of Surgically Placed Impella 5.0 and Central Extracorporeal Membrane Oxygenation Circuit in a Patient with Postcardiotomy Shock

The Impella 5.0, a percutaneously inserted left ventricular assist device, has been used to support patients who have severe heart failure or who are undergoing high-risk percutaneous coronary intervention. We report our surgical placement of the Impella 5.0, through a graft sewn to the aorta, to unload the left ventricle of a 59-year-old man who was undergoing venoarterial extracorporeal membrane oxygenation for postcardiotomy shock. The patient underwent successful placement of a long-term left ventricular assist device before his discharge from the hospital. The versatility of the Impella 5.0 is exemplified in this patient who was successfully bridged to long-term support.     

儿童室管膜瘤的临床研究进展

室管膜瘤是一种原发于神经上皮的中枢神经系统肿瘤，病变累及脑和脊髓，多发于儿童。基因分型的新分类方法，为室管膜瘤的治疗和预后评估提供了更为可靠的依据。室管膜瘤对辅助治疗的敏感性低是造成患儿预后较差的重要原因之一。该文对近年来儿童室管膜瘤的分型、诊断、治疗策略等进行综述。
