A comparison of transhiatal and transthoracic resections on the prognosis in patients with squamous cell carcinoma of the esophagus
2006
The aim of this study was to investigate the long-term prognosis for squamous cell carcinoma of the esophagus treated either by the transhiatal (TH) or by the transthoracic (TT) operative approach.Two hundred and twenty-nine patients (median age: 56 (29-84) years) with squamous cell carcinoma of the esophagus underwent esophageal resection between September 1985 and April 2004. In 70 patients, the transhiatal approach and in 159, the transthoracic approach was applied. An extended mediastinal lymph-node dissection was only carried out in the course of the transthoracic technique.Demographic data and tumor stages were comparable in both groups. A significantly better long-term survival was o…
Regurgitant flow in apparently normal valve prostheses: improved detection and semiquantitative analysis by transesophageal two-dimensional color-cod…
1990
In 128 patients with apparently normally functioning prosthetic valves ( n = 136) in the aortic position ( n = 79) and the mitral position ( n = 57), the prevalence of transprosthetic regurgitant flow was studied by use of transthoracic and transesophageal two-dimensional color-coded Doppler echocardiography. With the transthoracic approach, regurgitant flow was detected in early systole or diastole for 28% of the mitral prostheses and for 29% of the aortic prostheses. With transesophageal color-coded Doppler echocardiography, regurgitant jets were visualized for 95% of the mitral prostheses and for 44% of the aortic prostheses. In 40% of the Bjork-Shiley prostheses and 88% of the St. Jude …
