As a result of recent work-hours limitations and concerns for patient safety, innovations in extraclinical surgical simulation have become a desired part of residency education. Current simulation models, including cadaveric, animal, bench-top, virtual reality (VR) and robotic simulators are increasingly used in surgical training programs. Advances in telesurgery, three-dimensional (3D) printing, and the incorporation of patient-specific anatomy are paving the way for simulators to become integral components of medical training in the future...

BACKGROUND: Benign biliary stricture is a rare condition and the majority of the cases are caused by operative trauma or chronic inflammation based on various etiology. Although the initial results of endoscopic, percutaneous and surgical treatment are impressive, no comparison about long term stricture resolution is available. AIMS: The goal of this study was to compare the long term disease free survival in benign biliary strictures with various etiology after surgery, percutaneous transhepatic-and endoscopic treatment...

BACKGROUND: Innovation has been a central focus of the Department of Surgery at the Brigham and Women's Hospital since its very inception. Here we review examples of innovations originating in this Department and analyze factors that have been critical to successful innovation. Finally, we discuss challenges to sustainability of innovation in this Department. METHODS: Narrative review of the literature, interviews, and personal observations. RESULTS: Examples of innovations reviewed here were each dependent on three critical elements: 1) multidisciplinary collaboration among surgical innovators and individuals outside of surgery who offered complementary skills and expertise, 2) a rich institutional environment that sustained a diverse complement of innovators working in close proximity, and 3) Department Chairmen who facilitated the work of innovators and promoted their contributions, rather than seeking personal prestige or financial gain...

PURPOSE OF REVIEW: Tricuspid valve disease has received much less attention in terms of intervention. The main reason for this is the widely held belief that treatment of left-sided valve disease leads to resolution of functional tricuspid regurgitation. Recent data show that tricuspid regurgitation is not benign and that many patients will benefit from intervention at the time of left-sided valve surgery, or in isolated tricuspid disease. This review describes the latest surgical and interventional options and strategies...

BACKGROUND: Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservatively treated adolescents and of adults undergoing Roux-en-Y gastric bypass, in the Adolescent Morbid Obesity Surgery (AMOS) study...

BACKGROUND: Although it is valuable for detecting distant metastases, identifying recurrence, and evaluating responses to chemotherapy, the role of (18)F-fluorodeoxyglucose positron-emission tomography/computed tomography ((18)F-FDG PET/CT) in assessing locoregional nodal status for initial staging of breast cancer has not yet been well-defined in clinical practice. In the current report, we describe a new PET probe-based clinical approach, with evaluation of the technical performance of a handheld high-energy gamma probe for intraoperative localization of breast carcinomas, and evaluation of lymph node metastases during radio-guided oncological surgery...

The recent technical advances allow the use in practice of three-dimensional echocardiography in children especially through the new high frequency matrix probe. It is difficult or even impossible to hold breathing during children' acquisition so to avoid motion full volume artifact, one beat and live 3D modes are suitable. 3D echocardiography is more accurate than 2D to assess the size, location, and relationship with surrounding structures of atrial and ventricular septal defects and thus helps in the therapeutic decision...

Premaxillary tooth loss and bone deficiency or atrophy often occur in facial trauma. Onlay bone graft and implants have so far been the best means of restoring function and esthetic appearance. Void space between the graft and the jaw bone, over projection and mucosal trauma can cause mucosal dehiscence, bone exposure, or resorption and can compromise implant survival. Virtual surgical planning using 3-dimensional printing technology has improved the efficiency of craniofacial surgery. The drawbacks of this technology are its cost and time-consuming preparation...

REVIEW
C Hulet, G Rochcongar, C Court
Under the new categorization introduced by the Health Authorities, ambulatory surgery (AS) in France now accounts for 50% of procedures, taking all surgical specialties together. The replacement of full hospital admission by AS is now well established and recognized. Health-care centers have learned, in coordination with the medico-surgical and paramedical teams, how to set up AS units and the corresponding clinical pathways. There is no single model handed down from above. The authorities have encouraged these developments, partly by regulations but also by means of financial incentives...

BACKGROUND: The treatment of pilonidal sinus disease still remains challenging. Despite many non-surgical and surgical methods, no consensus emerged for the best treatment. We describe a new innovative technique consisting in the destruction of the pilonidal cyst with a radial laser probe (FILAC(TM), Biolitec, Germany). The energy delivered causes the destruction of the sinus epithelium and the simultaneous obliteration of the tract. METHOD: In December 2015, we retrospectively studied the data of our 40 first patients operated with this technique between September 2014 and September 2015...

On November 27, 2005, Isabelle Dinoire underwent the world's first partial face transplant in Amiens (France) after a dog attack had left her face severely disfigured. The abrupt surgical leap found the medical community and society unprepared to deal with the scientific, ethical, and societal implications of a surgical procedure that was striving to transition from sci-fi novels to science. Today, 10 years and over 35 transplants later, public opinion has become accustomed to the concept of "face restoration" through transplantation...

INTRODUCTION: One-stage implant-based breast reconstruction has been recently improved by the introduction of biological [acellular dermal matrix (ADM)] and synthetic meshes. Advantages of ADMs in implant-based breast reconstruction derive from the expansion of the space available for the direct positioning of an implant, but their use could be associated with several complications. Although the majority of complications can be easily managed, mistakes in dealing with the first clinical signs of a potential adverse event can lead to implant loss...
