BACKGROUND: Augmented Reality (AR) guidance is a technology that allows a surgeon to see sub-surface structures, by overlaying pre-operative imaging data on a live laparoscopic video. Our objectives were to evaluate a state-of-the-art AR guidance system in a tumor surgical resection model, comparing the accuracy of the resection with and without the system. Our system has three phases. Phase 1: using the MRI images, the kidney's and pseudotumor's surfaces are segmented to construct a 3D model...

OBJECTIVE: Analysis of various parameters related to the patient, the disease, and the needed surgical maneuvers to develop guidance for preoperative selection of the appropriate and the best approach for a given patient. Rapid advances in minimally invasive surgical technology are fascinating and challenging alike. It can be difficult for surgeons to keep up with new modalities that come on to the market place and to assess their true value, i.e., distinguish between fashionable trends versus scientific evidence...

Intraoperative imaging is vital for accurate placement of instrumentation in spine surgery. However, the use of biplanar fluoroscopy and other intraoperative imaging modalities is associated with the risk of significant radiation exposure in the patient, surgeon, and surgical staff. Radiation exposure in the form of ionizing radiation can lead to cellular damage via the induction of DNA lesions and the production of reactive oxygen species. These effects often result in cell death or genomic instability, leading to various radiation-associated pathologies including an increased risk of malignancy...

REVIEW
Deepak Gupta, Jared Ching, Paul E Tornambe
The successful detection of retinal breaks is a critical step in rhegmatogenous retinal detachment (RRD) surgery in order to prevent persistent/recurrent RRDs. Not all retinal breaks causing retinal detachments are obvious. Retinal breaks may be obscured due to opacities that are either anterior-segment related, lens related or posterior-segment related. Rules to identify breaks based on sub-retinal fluid (SRF) configuration are more difficult to apply in pseudophakic, aphakic, encircled eyes, and eyes with repeat detachments and those with proliferative vitreoretinopathy (PVR)...

Resection is the gold standard in the treatment of liver metastases from colorectal cancer. An internal cooled radiofrequency electrode was described to achieve tissue coagulation to a greater margin width. The aim of this study is to determinate if a RF-assisted transection device (RFAT) has any effect on local hepatic recurrence (LHER) compared to conventional technologies. A study population of 103 patients who had undergone a hepatic surgical resection was retrospectively analysed. Patients were classified into two groups according to the device used: a RF-assisted device (RFAT group; n = 45) and standard conventional devices (control group; n = 58)...

PURPOSE: This review aims to summarise the hybrid modality radioguidance techniques currently in clinical use and development, and to discuss possible future avenues of research. Due to the novelty of these approaches, evidence of their clinical relevance does not yet exist. The purpose of this review is to inform nuclear medicine practitioners of current cutting edge research in radioguided surgery which may enter standard clinical practice within the next 5-10 years. Hybrid imaging is of growing importance to nuclear medicine diagnostics, but it is only with recent advances in technology that hybrid modalities are being investigated for use during radioguided surgery...

Amputation is not a defeat or failure of treatment, but an effective management strategy for certain conditions in the pediatric population. The principles of management, especially in the pediatric population, have not changed. Current surgical strategies focus on providing an optimal residual limb for prosthetic fitting. New technology provides improvement in the design and fabrication of prosthetic devices.

INTRODUCTION: Wide-necked bifurcation aneurysms (WNBAs) present unique technical challenges for both endovascular and surgical treatments which aim to achieve complete occlusion of the aneurysm without compromising the patency of the incorporated regional parent vessels. We present a meta-analysis of traditional therapies for WNBAs to provide critical benchmarks for safety and effectiveness. METHODS: Following a systematic search of the literature and the application of pre-specified appropriateness criteria, 43 (including 2794 aneurysms treated) and 65 (including 5366 patients treated) references with sufficient detail were identified to include in a meta-analysis of efficacy and safety, respectively...

REVIEW
Bryden J Stanley
Open wounds are regularly addressed in veterinary medicine and can be challenging to manage, especially when there is significant loss of full-thickness skin. Traditional wound dressings are being replaced by modern synthetic materials, biologic wound dressings, and mechanical technologies to augment healing. Negative pressure wound therapy (NPWT) is one of the most successful mechanical adjuncts to wound healing. Experience with NPWT in veterinary medicine is not as extensive as in human medicine but reports have been positive...

Glenn S Murphy
Neuromuscular monitoring devices were introduced into clinical practice in the 1970s. Qualitative neuromuscular monitors, or peripheral nerve stimulators, provide an electrical stimulus to a motor nerve and the response of corresponding muscle subjectively evaluated. A standard peripheral nerve stimulator provides several patterns of nerve stimulation, including train-of-four (TOF), double-burst, tetanic, and post-tetanic count. Qualitative (and quantitative) monitors are needed to determine onset of neuromuscular blockade, maintain the required depth of muscle relaxation during the surgical procedure, and assess an appropriate dose of reversal agent...

REVIEW
Dilan A Patel, Jian L Campian
Malignant epidural spinal cord compression (MESCC) is an oncologic emergency with the potential for devastating consequences for patients if not promptly diagnosed and treated. MESCC is diagnosed by imaging. MRI is by far the most sensitive test, preferably with gadolinium. Once the diagnosis of MESCC is suspected, patients with neurologic deficits should receive prompt administration of dexamethasone with a 10-mg IV loading dose followed by 4 mg every 6 h. Quick taper is recommended once the definitive treatment is established...

REVIEW
Eric Chung
Male stress urinary incontinence (SUI) remains a debilitating condition that adversely impacts all domains of quality of life and is associated with significant social stigma and health economic burden. The incidence of post-prostatectomy urinary incontinence (PPI) depends on the definition of urinary incontinence and the length of patient follow up. In patients with persistent PPI following failure of conservative measures, surgical treatment is recommended although there is no published guideline on when surgery should be performed, and what the best surgical option is...

REVIEW
John Chang, Dominic Lee
Stress urinary incontinence (SUI) has always been a major health issue for women. With the progression of technology and surgical techniques, mid urethral slings (MUS) used in both transvaginal and transobturator routes have become the gold standard in the treatment of SUI. There is ample short to mid-term data confirming the efficacy and safety in using MUS in treating SUI in women. However, long-term data supporting the use of MUS in women to treat SUI is scarce. There has been much controversy surrounding the US Food and Drug Administrations' (FDA) public notification of potential complications surrounding the use of transvaginal mesh, which has been magnified and generalised by the media; but despite this there has still been substantial growth and uptake of MUS for treating SUI...

BACKGROUND: In the care of patients with congenital heart disease, percutaneous interventional treatments have supplanted many surgical approaches for simple lesions, such as atrial septal defect. By contrast, complex congenital heart defects continue to require open-heart surgery. In single-ventricle patients, a staged approach is employed, which requires multiple open-heart surgeries and significant attendant morbidity and mortality. A nonsurgical transcatheter alternative would be attractive...
