Role of Transesophageal Echocardiography in Dissection of the Aorta and Evaluation of Degenerative Aortic Disease
1993
The combination of different ultrasound techniques such as transthoracic, suprasternal, subcostal, and TEE has a high sensitivity and specificity in the diagnosis of aortic dissection. Limitations of this combined ultrasound technique are related to the visualization of the ascending part of the aortic arch, which, because of the interposition of the trachea, cannot be visualized completely. The beginning or end of a dissection in this part of the aorta may be misinterpreted. However, false-negative results are rare. False-positive results due to artifacts resulting from reverberations in an ectatic ascending aorta must be taken into account. The most important diagnostic goals in acute or …
Dilated azygos arch mimicking an aortic arch anomaly during thoracic surgery
2017
Cardiovascular malformations are frequently associated in patients with esophageal atresia (EA). We observed azygos continuation mimicking an aortic arch anomaly in four newborns with type III EA. They presented concomitant rib anomalies indicating a common developmental defect. Foreknowledge is important for planning thoracotomy or interventional cardiac catheterization in this population.
Influence of cell proportions and proliferation rates on FDG uptake in squamous-cell esophageal carcinoma: a PET study.
2008
We investigated the influence of cell proportions and proliferation activities on tumor maximum standard uptake value (SUV(max)) in patients with squamous-cell esophageal cancer (SCEC).Sixteen (16) patients with untreated SCEC were examined with (18)F-flourodeoxyglucose positron emission tomography (FDG-PET). The tumor SUV(max) were calculated. Tumors were resected by transthoracic esophagectomy. Tissues were stained with hematoxylin and eosin for the measurement of cell proportions and MIB-1 for measurement of proliferation indices (PIs). Tumor SUV and histologic data were related by using multiple linear regression analysis.The mean proportion of tumor cells in the tumor site was 58.1% (+…
DNA image cytometry. A prognostic tool in squamous cell carcinoma of the esophagus?
1991
In 45 patients who underwent an esophagus resection due to a squamous cell carcinoma, in addition to the TNM classification and usual morphologic criteria, the paraffin-embedded material underwent deparaffinization, was rehydrated, and was mechanically and enzymatically processed into a single-cell solution. For evaluating the DNA histogram this was analyzed with the help of automatic single-cell cytophotometric study. The method, contrary to that of flow cytometric study, allows for the selective analysis of tumor cells due to the electronically, previously given selection criteria, whereas artifacts, stroma, and infection cells remain excluded from analysis. The multivariate analysis show…
Isolated RV diverticulum: diagnosis by cardiac magnetic resonance and 3D TEE
2014
A 16-year-old male was referred to our hospital because of exertional chest pain. There was no personal or family history of any cardiovascular disease. Findings on physical examination and vital signs were normal. An ECG showed a right bundle superoanterior zonal block pattern with low potentials in frontal plane and intraventricular conduction delay (QRS Complex 120 msg) with pseudo-epsilon wave in V1 …
Prevalence and appropriateness of drug prescriptions for peptic ulcer and gastro-esophageal reflux disease in a cohort of hospitalized elderly
2011
Abstract Background Proton pump inhibitors (PPI) are among the most commonly prescribed medicines and their overuse is widespread in both primary and secondary care. Inappropriate prescription is of particular concern among elderly patients, who have often multiple comorbidities and need many drugs. Methods We evaluate the appropriateness of drugs for peptic ulcer or gastro-esophageal reflux disease (GERD) in a sample of elderly patients (65 years old or older) at admission and discharge in 38 internal medicine wards between January 2008 and December 2008, according to the presence of specific conditions or gastro-toxic drug combinations. Results Among 1155 patients eligible for the analysi…
The Impact of Endoscopic Ultrasound and Computed Tomography on the TNM Staging of Early Cancer in Barrett's Esophagus
2006
Computed tomography (CT) and endoscopic ultrasound (EUS) are part of the regular staging protocol in esophageal cancer. The value of the two methods was assessed in patients with early cancer in Barrett's esophagus.One hundred consecutive patients (median age 64 yr, interquartile range [IQR] 58-72) with suspected early cancer in Barrett's esophagus who were referred to our hospital for endoscopic therapy were prospectively included in a standardized staging program with upper gastrointestinal endoscopy, EUS (7.5 MHz in all cases plus 12.5 or 20 MHz for elevated and/or depressed lesions), CT of the chest and upper abdomen, and abdominal ultrasonography. The results were summarized in accorda…
Mapping of failures after radiochemotherapy in patients with non-metastatic esophageal cancer: A posteriori analysis of the dose distribution in the …
2015
Abstract Background and purpose We aimed to evaluate the patterns of loco-regional failure (LRF) after exclusive chemoradiotherapy (eCRT) for esophageal cancer with respect to planned dose and/or the incidental (unplanned) dose outside target volumes. Materials and methods Co-image registration of CT or 18 F-FDG PET-CT at the time of failure (tf) and at the time of CRT (t0) was performed in 34 patients with LRF. Dosimetric parameters with regard to local failure (LF), nodal failure (NF) and involved nodal stations (NS) were derived. Results Twenty-two patients (64.7%) had LF, the majority of which (95.5%) were located at the epicenter of the GTV of the primary tumor. The mean doses recalcul…
The economic burden of endoscopic treatment for anastomotic leaks following oncological Ivor Lewis esophagectomy
2019
BackgroundComplications after surgery for esophageal cancer are associated with significant resource utilization. The aim of this study was to analyze the economic burden of two frequently used endoscopic treatments for anastomotic leak management after esophageal surgery: Treatment with a Self-expanding Metal Stent (SEMS) and Endoscopic Vacuum Therapy (EVT).Materials and methodsBetween January 2012 and December 2016, we identified 60 German-Diagnosis Related Group (G-DRG) cases of patients who received a SEMS and / or EVT for esophageal anastomotic leaks. Direct costs per case were analyzed according to the Institute for Remuneration System in Hospitals (InEK) cost-accounting approach by c…
Evaluation of Esophageal Motility Using Multichannel Intraluminal Impedance in Healthy Children and With Gastroesophageal Reflux
2010
Abstract OBJECTIVE: : Multichannel intraluminal impedance (MII) directly evaluates esophageal bolus transport. There is a good correlation between MII and manometry in healthy adults, but there are no reports concerning children.The aim of the present study was to determine normal values of esophageal motility using only impedance measurements in healthy children and in a pediatric population with gastroesophageal reflux (GER). PATIENTS AND METHODS: : We described in the present study 60 children submitted to pH-MII for 24 hours for suspected GER. Patients were divided into 2 different groups on the basis of their pH-MII report. Group 1 patients showed acid GER, whereas group 2 patients had…
