BACKGROUND: -In patients with a dilated proximal ascending aorta and trileaflet aortic valve (TAV), we sought to assess a) factors independently associated with increased long-term mortality and b) the incremental prognostic utility of indexing aortic root to patient height. METHODS: -We studied consecutive patients with a dilated aortic root (≥4 cm) that underwent echocardiography and gated contrast-enhanced thoracic aortic computed tomography or magnetic resonance angiography between 2003-2007...

A variety of surgical procedures exist for repair of both traumatic and degenerative osseous and soft-tissue pathologic conditions involving the foot and ankle. It is necessary for the radiologist to be familiar with these surgical procedures, so as to assess structural integrity, evaluate for complicating features, and avoid diagnostic pitfalls. Adequate interpretation of postoperative changes often requires access to surgical documentation to evaluate not only the surgery itself but the expected timeline for resolution of normal postoperative changes versus progressive disease...

BACKGROUND: Metal-on-Metal (MoM) total hip arthroplasties (THA) are associated with pseudotumor formation and high revision rates. This prospective study analysed the clinical and wear analyses of 9 large Metal-on-Metal (MoM) total hip arthroplasties (THA) to understand the underlying mechanisms of failure. The MoM bearings were revised for multiple reasons; the main reason was pseudotumor formation. MATERIALS AND METHODS: From 2006 till 2010 the Reinier de Graaf Hospital implanted 160 large head M2a-Magnum™ (Biomet Inc...

INTRODUCTION: When total thyroidectomy is performed for substernal goitre, a high risk of morbidity is reported. Advanced vessel sealing devices provide an alternative to the conventional clamp and tie technique. The aim of this study is to compare the outcome of patients who underwent total thyroidectomy for substernal goitre using Ligasure Small Jaw, Harmonic Focus, or conventional technique. METHODS: Between 2011 and 2014, from a population of 393 patients undergoing surgery for thyroid disease, 75 (49 females, 26 males, mean age: 57...

PURPOSE: Germline mutations in several genes confer a relevant lifetime risk of gastric cancer. In this context, an increasing involvement of a surgeon can be seen, mainly with the question of performing a prophylactic operation. METHODS: Patients with hereditary tumor syndromes predisposing for gastric cancer who received care leading to prophylactic total gastrectomy in our Center for Hereditary Tumor Syndromes were analyzed. For each patient, the multidisciplinary decision-making process, the perioperative course, and the histopathologic findings were assessed...

BACKGROUND: The impact of hospital and surgeon volume on the treatment outcome based on data obtained from cohort and register studies has been controversially discussed in the international literature. The results of large-scale prospective observational studies within the framework of clinical healthcare research may lead to relevant recommendations in this ongoing discussion. MATERIAL AND METHODS: Within the framework of the prospective multicenter German Gastric Cancer Study 2 (QCGC 2), from 1 January 2007 to 31 December 2009 a total of 2897 patients with the histological diagnosis of gastric cancer from 140 surgical departments were registered and analyzed...

PURPOSE: Shame is an ineffective tool in residency education that often results in depression, isolation, and worse patient care. This study aimed to assess burnout, depersonalization, and personal achievement levels in current oral and maxillofacial surgery (OMS) residents, to assess the prevalence of the use of shame in OMS residency training, and to determine whether there is a relation between shame exposure and resident burnout, depersonalization, and personal achievement levels...

BACKGROUND CONTEXT: Spine surgeons employ a high volume of imaging in the diagnosis and evaluation of spinal pathology. However, little is known regarding patients' knowledge of the radiation exposure associated with these imaging techniques. PURPOSE: To characterize spine patients' knowledge regarding radiation exposure from various imaging modalities. STUDY DESIGN/SETTING: A cross-sectional survey study. PATIENT SAMPLE: One hundred patients at their first clinic visit with a single spine surgeon at an urban institution...

Comparison of immediate postoperative results of patients undergoing cemented total knee arthroplasty with and without ischemia. Observational, cross-sectional, retrospective, analytical, single-center study that included 180 patients who underwent total knee arthroplasty from 2011 to 2014: 120 without ischemia, 60 with ischemia. Mean age was 70 years with SD ± 7. Criteria to assess the immediate postoperative results include intraoperative bleeding, hemoglobin differential and pain. Exclusion criteria comprised patients being treated at a pain clinic, those on anticoagulants, with a history of bleeding disorders, psychiatric conditions, kidney failure or those intolerant to NSAIDs...

INTRODUCTION: Breast conserving surgery (BCS) aims to remove a breast cancer completely and obtain clear margins. Complete excision is essential to reduce the risk of local recurrence. The ClearEdge™ (CE) imaging device examines margins of excised breast tissue intra-operatively. The aim of this study was to investigate the potential of the device in detecting margin involvement in patients having BCS. METHODS: In Phase-1 58 patients underwent BCS and had 334 margins assessed by the device...

INTRODUCTION: Musculoskeletal disease (MSD) is a major cause of disability in the global burden of disease, yet data regarding the magnitude of this burden in low and middle-income countries (LMICs) are lacking. The Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey was designed to measure incidence and prevalence of surgically treatable conditions, including MSD, in patients in LMICs. METHODS: A countrywide survey was done in Nepal using SOSAS in May-June, 2014...

PURPOSE: While adult bowel anastomoses are typically performed with staplers, neonatal small bowel anastomoses have traditionally been performed in a hand-sewn manner due to the large size of surgical staplers. The purpose of this study was to compare stapled anastomosis using a newly available, 5-mm laparoscopic stapler to a hand-sewn anastomosis in an open animal model. METHODS: Twenty anastomoses were performed by two general surgery residents (10 stapled and 10 hand-sewn) in an adult New Zealand white rabbit...

BACKGROUND: Stable femoral fixation during uncemented total hip arthroplasty is critical to allow for subsequent osseointegration of the prosthesis. Varying stem designs provide surgeons with multiple options to gain femoral fixation. OBJECTIVE: The purpose of this study was to compare the initial fixation stability of cylindrical and tapered stem implants using two different underreaming techniques (press-fit conditions) for revision total hip arthroplasty (THA)...

The aim of this study is the evaluation of the anatomical structures of sphenoid sinus ostium used as a reference point for transsphenoidal surgery by cone beam computed tomography. The authors' study was performed using the cone-beam computed tomography images of 16 to 82-year old 200 (112 female, 88 male) patients (Newton 5G, Verona, Italy). Septum deviation of sphenoid sinus and the distance between 2 ostia were evaluated by coronal and axial sections, respectively. Pneumatization degree of sphenoid sinus, diameter of sphenoid sinus ostium, and distance lower edge of superior turbinate to sphenoid sinus ostium were measured by using sagittal sections...

BACKGROUND: Spectral domain optical coherence tomography (SD-OCT) has become a standard diagnostic tool in the surgical management of vitreomacular interface disorders. The high-resolution cross-sectional information obtained from SD-OCT is a perfect complement to vitreoretinal surgery. It provides detailed intraoperative anatomical views that are not possible with a microscope. OBJECTIVE: To investigate the value of intraoperative real-time OCT with respect to improvement of surgical techniques in the management of vitreomacular disorders...

OBJECTIVE Antiepileptic drugs (AEDs) are often administered prophylactically following brain tumor resection. With conflicting evidence and unestablished guidelines, however, the nature of this practice among tumor surgeons is unknown. METHODS On November 24, 2015, a REDCap (Research Electronic Database Capture) survey was sent to members of the AANS/CNS Section on Tumors to query practice patterns. RESULTS Responses were received from 144 individuals, including 18.8% of board-certified neurosurgeons surveyed (across 86 institutions, 16 countries, and 5 continents)...
