:  Introduction and aims. Cholangiocarcinomas are a heterogeneous group of tumors that can be classified into three clinically distinct types of cancers, intrahepatic, perihilar and distal cholangiocarcinoma. The inconsistent use of nomenclature for these cancers has obscured a true knowledge of the epidemiology, natural history and response to therapy of these cancers. Our aims were to define demographic characteristics, management and outcomes of these three distinct cancer types. MATERIALS AND METHODS: A retrospective study of patients enrolled in an institutional cancer registry from 1992 to 2010...

Background: Medical treatment requires the implementation of existing evidence in the decision making process in order to be able to find the best possible diagnostic, therapeutic or prognostic measure for the individual patient based on the physician's own expertise. Clinical trials form the evidence base and ideally, their results are assembled, analyzed, summarized, and made available in systematic review articles. Beside planning, conducting, and evaluating clinical trials in conformity with GCP (good clinical practice), it is essential that all results of conducted studies are publicly available in order to avoid publication bias...

The significant increase in the prevalence of obesity has led to an increase in the number of obese women who become pregnant. In this setting, in recent years, there has been an exponential rise in the number of bariatric procedures, with approximately half of them performed in women of childbearing age, and a remarkable surge in the number of women who become pregnant after having undergone bariatric surgery (BS). These procedures entail the risk of nutritional deficiencies, and nutrition is a crucial aspect during pregnancy...

The gold standard of anterior cruciate ligament (ACL) injuries is currently single-bundle autograft reconstruction. However, many disadvantages of reconstructive surgery exist, such as: anterior knee pain, muscle atrophy, and loss of range of motion. In addition, native kinematics are not restored, and osteoarthritis is not prevented. Finally, revision surgery, if necessary, can be problematic due to tunnel widening, tunnel malpositioning, and preexisting hardware. Ligament preservation includes preservation of native tissues in order to optimize the biologic aspects, while decreasing the invasive nature of reconstructive surgery...

Nerve-sparing surgery is an emerging technique for surgery-related dysfunction. Within the past 15 years, an essential progress in recognition and understanding of the anatomy of the pelvic autonomous nervous system has been made. Surgical preservation of vegetative nerves has become well known in many cancer centers. The technique has led to improvement of the quality of life following oncologic radical procedures. Positive results have led to the adoption of such techniques in the surgical treatment of deep infiltrating endometriosis in an aim to prevent urinary, rectal, and sexual dysfunction...

OBJECTIVES: The objective of this retrospective planning study was to find a contouring definition for the rectum as an organ at risk (OAR) in curative 3D external beam radiotherapy (EBRT) for prostate cancer (PCa) with a predictive correlation between dose-volume-histograms (DVH) and rectal toxicity. METHODS: In a pre-study the planning CT scans of n= 23 patients with PCa receiving definitive EBRT were analysed. The rectum was contoured according to 13 different definitions, and the dose distribution was correlated with the respective rectal volumes by generating DVH curves...

Topical haemostatic agents have become an essential tool to assist with the control of bleeding during surgery as well as to facilitate wound closure. The imaging appearance of these agents can overlap that of abscess or tumour. Knowledge of the appearance of these various agents on ultrasound and CT is crucial to avoid misdiagnosing pathology, potentially resulting in unnecessary interventional procedures.

Oral and Maxillofacial Surgery (OMFS) remains an enigmatic specialty in Irish medicine and many students are unaware of its scope and the unique career pathway involved. We performed a multicentre cross-sectional study to identify their ability to identify the requirements for entry to specialty training year 3 (ST3) in OMFS, to assess their awareness of OMFS surgeons, and their general awareness of, and exposure to, the specialty. Data were collected through an electronic questionnaire. Participants were asked to select the most suitable surgical specialty to treat a number of common conditions in the head and neck, and to choose the requirements they deemed essential for specialist training...

Many animal models have been established for the study of myocardial remodeling and heart failure due to its status as the number one cause of mortality worldwide. In humans, a pathologic occlusion forms in a coronary artery and reperfusion of that occluded artery is considered essential to maintain viability of the myocardium at risk. Although essential for myocardial recovery, reperfusion of the ischemic myocardium creates its own tissue injury. The physiologic response and healing of an ischemia/reperfusion injury is different from a chronic occlusion injury...

BACKGROUND: Adolescent idiopathic scoliosis is a complex three-dimensional deformity of the spine characterized by deformities in the sagittal, coronal, and axial planes. Spinal fusion using pedicle screw instrumentation is a widely used method for surgical correction in severe (coronal deformity, Cobb angle > 45°) adolescent idiopathic scoliosis curves. Understanding the anatomic difference in the pedicles of patients with adolescent idiopathic scoliosis is essential to reduce the risk of neurovascular or visceral injury through pedicle screw misplacement...

Bimanual surgery enhances surgical effectiveness and is required to successfully accomplish complex microsurgical tasks. The essential advantage is the ability to simultaneously grasp tissue with one hand to provide counter traction or exposure, while dissecting with the other. Towards enhancing the precision and safety of bimanual microsurgery we present a bimanual SMART micro-surgical system for a preliminary ex-vivo study. To the best of our knowledge, this is the first demonstration of a handheld bimanual microsurgical system...

: Knowledge of the mechanism underlying post-operative atrial fibrillation (PoAF) is essential for development of preventive measures. The incidence and characteristics of both PoAF and supraventricular premature beats triggering PoAF, their interrelationship and alterations over time have never been examined. The goal of this study is therefore to examine the correlation between the incidence and characteristics of supraventricular premature beats (SVPBs) and PoAF episodes in patients undergoing CABG in the first five post-operative days...

REVIEW

Laparoscopic or robotic minimally invasive approaches have become the standard of care for many urological pediatric surgical procedures. Anesthetic concerns for conventional and robotic laparoscopy are similar since they both require insufflations of CO2 to allow visualization of surgical field and perform surgery. Even if required insufflation pressures and volumes are lower in pediatric patients (given the small size of the abdomen and laxity of the abdominal walls), the associated increase of intra-abdominal pressure, along with absorption of CO2 and surgical positioning requirement, may result in neurendocrine and mechanical impact capable to mine cardiopulmonary function...

ABSTRACT INTRODUCTION: Surgical treatment of tumors, particularly metastases to the spine, has become increasingly common owing to the progress in anesthesiology and spinal surgery and greater detectability. The patients qualified for surgeries are those with mechanical pain, fracture or at risk of vertebral fracture or neurological complications. The basis for qualification for different types of surgeries is clinical and imaging examination, particularly MRI and CT. Qualification should always be multidisciplinary and requires understanding and knowledge of its most essential aspects...
