BACKGROUND Repair of an abdominal aortic aneurysm (AAA) is undertaken to prevent rupture. Intervention is by either open repair (OR) or a more minimally invasive endovascular repair (EVAR). Quality-of-life (QoL) analysis is an important health outcome and a number of single studies have assessed QoL following OR and EVAR. This was a meta-analysis of(More)
BACKGROUND Fundoplication is a leading application of robotic surgery in children, yet the learning curve for this procedure (RF) remains ill-defined. This study aims to identify various learning curve transition points, using cumulative summation (CUSUM) analysis. METHODS A prospective database was examined to identify RF cases undertaken during(More)
OBJECTIVE To investigate the influence of clear surgical resection margin width on disease recurrence rate after intentionally curative resection of colorectal liver metastases. BACKGROUND There is consensus that a histological positive resection margin is a predictor of disease recurrence after resection of colorectal liver metastases. The dispute,(More)
Patients with myelodysplastic syndromes (MDS) have high frequencies of cytogenetic abnormalities and evidence is accumulating of associations between exposure history and primary MDS. The objective of this article is to examine the relationship between histories of occupational or environmental exposure and presence of cytogenetic abnormalities. A case(More)
Qualitatively distinct patterns of cardiovascular and neuroendocrine responses were observed in male college students during mental work and during sensory intake task performance. During mental work, Type A (coronary-prone) subjects showed greater muscle vasodilatation and more enhanced secretion of norepinephrine, epinephrine, and cortisol than Type B(More)
INTRODUCTION Minimally invasive surgery (MIS) is a complex task requiring dexterity and high level cognitive function. Unlike surgical 'never events', potentially important (and frequent) manual or cognitive slips ('technical errors') are underresearched. Little is known about the occurrence of routine errors in MIS, their relationship to patient outcome,(More)
BACKGROUND The cumulative summation (CUSUM) method for learning curve analysis remains under-utilized in the surgical literature in general, and is described in only a small number of publications within the field of pediatric surgery. This study introduces the CUSUM analysis technique and applies it to evaluate the learning curve for pediatric(More)
BACKGROUND The most common sites of metastasis from colorectal cancer (CRC) are hepatic and pulmonary; they can present simultaneously (hepatic and pulmonary metastases) or sequentially (hepatic then pulmonary metastases, or vice versa). Simultaneous disease may be aggressive, and thus may be approached with caution by the clinician. The aim of this study(More)
INTRODUCTION Sinusoidal obstructive syndrome (SOS) is well associated with the use oxaliplatin-based chemotherapy, and represents a spectrum of hepatotoxicity, with nodular regenerative hyperplasia (NRH) representing the most significant degree of injury. The aim of this study was to determine the prevalence of NRH in patients undergoing resection of(More)
