BACKGROUND Endoscopic resection and ablation have advanced the treatment of intramucosal esophageal adenocarcinoma and have been promoted as definitive therapy for selected superficial submucosal tumors. Controversy exists regarding the prevalence of nodal metastases at various depths of mucosal and submucosal invasion. Our aim was to clarify this(More)
The optimal strategy for coronary revascularization remains controversial. Currently, most surgical revascularizations are performed with the use of cardiopulmonary bypass (ONCAB), yet over the past 20 years off-pump coronary artery bypass grafting (OPCAB) has been increasingly used because of the increased awareness of the deleterious effects of(More)
Large-scale, population-based analyses of the demographics, management, and healthcare resource utilization of patients with an intrathoracic stomach are largely unknown, an issue which has become more important with the aging of the population. Our objective was to understand the magnitude of the problem and to assess clinical outcomes and hospital costs(More)
BACKGROUND The development of high-resolution (HRM) catheters and software displays of manometric recordings in color-coded pressure plots has changed the diagnostic assessment of esophageal disease. HRM may offer advantages over conventional methods, including improved identification of motility disorders, hiatal hernia, and outflow obstruction, and ease(More)
Studies of positron emission tomography (PET) have focused mainly on tumor staging. The role of PET in predicting survival has received less attention. We sought to assess the relationship of pretreatment maximum standard uptake value (SUVmax) to survival in surgical patients with esophageal cancer. The study consisted of 72 esophagectomy patients (60 with(More)
Given our aging population, patients with an intrathoracic stomach are an increasing clinical problem. The timing of repair remains controversial, and most reports do not delineate morbidity of emergent presentation. The aim of the study was to compare the morbidity and mortality of elective and emergent repair. Study population consisted of 127 patients(More)
BACKGROUND Modern-day concepts about the pathogenesis of an intrathoracic stomach include crural diaphragm muscular deterioration, loss of phrenoesophageal ligament integrity, and presence of abdominothoracic pressure gradients. The role of spinal abnormalities has received little attention. Based on clinical observation, we hypothesized that kyphosis and(More)
BACKGROUND It is unknown whether purported benefits of off-pump coronary artery bypass grafting are patient-specific within the Society of Thoracic Surgeons National Cardiac Database or dependent on center volume or operating surgeon. METHODS The Society of Thoracic Surgeons National Cardiac Database was queried for all patients undergoing nonemergency,(More)
BACKGROUND Although esophagectomy provides the highest probability of cure in patients with esophageal cancer, many candidates are never referred for surgery. We hypothesized that esophagectomy for esophageal cancer is underused, and we assessed the prevalence of resection in national, state, and local cancer data registries. STUDY DESIGN Clinical stage,(More)
BACKGROUND Metabolic diseases are thought to negatively impact the long-term survival of cardiac patients and have been shown to be associated with reduced durability of bioprosthetic heart valves. The purpose of this study is to determine whether long-term survival of post-valve replacement patients is affected by the presence of metabolic disease, and(More)
