BACKGROUND: Postoperative internal hernia (IH) is a potentially life-threatening acute protrusion of viscus through an iatrogenic mesenteric defect. In our retrospective study of 1943 consecutive gastric cancer (GC) patients who had undergone surgery, the incidence of IH after laparoscopic total gastrectomy (LTG) was 4.9%.1 This high incidence seems to be caused by decreased adhesion formation after LTG. There is no consensus regarding orifice management during robotic total gastrectomy (RTG)...

BACKGROUND: Several surgical options for the reconstruction of massive bone defects have been described and include biologic methods with autografts and allografts, and the use of tumor endoprostheses (total femoral replacement, TFR). Several types of modular TFR are available, but nevertheless unpredictable outcomes and high complication rates have been described from most authors. The present study aims to compare results after TFR performed with modular total femur prosthesis MML (Fa...

OBJECTIVES: The objective of this study is to analyse the flow conditions in the AFX and Nellix endografts (EGs) accounting for their postimplantation configuration in patients with an endovascular aneurysm repair-treated abdominal aortic aneurysm. METHODS: We reconstructed post-endovascular aneurysm repair computed tomography scans of patients treated with an AFX or Nellix EG creating post-implantation EG models. We examined 16 patients, 8 in each group. The blood flow properties were obtained by computational fluid dynamics simulations and were subsequently compared with physiological infrarenal blood flow properties measured in 5 healthy subjects...

OBJECTIVE: Interdisciplinary work including surgery and additive radiotherapy is often needed for the therapy of tumours. Beneath this, brachytherapy is an important part of the radiotherapy. It was first used over 100 years ago and is in regular use after the development of afterload technology in the early 1970s. Today it is often used in different tumour therapies, for example in soft tissue sarcoma or breast tumours, in order to decrease the risk of local recurrence. Concerning its benefits, higher doses could be used because of the localized effect with equivalent local control rate and less toxicity of treatment...

The orthopaedic military surgeons deployed in operations are led to perform soft tissue coverage on the lower limb. The purpose of this study was to evaluate if flaps performed by surgeons' non-specialist in reconstructive surgery are associated with good outcome. All patients operated for a flap on the leg in French Forward Surgical Team deployed in theatre of operations between 2003 and 2013 were retrospectively reviewed. Forty-nine patients were included, for a total of 54 flaps' procedures. Indications were open fractures in 25 cases and osseous infections in 29 cases...

Deducing the scapular positions of extinct tetrapod skeletons remains difficult, because the scapulae and rib cage are connected with each other not directly by skeletal joint, but by thoracic muscles. In extant non-testudine quadrupedal tetrapods, the top positions of the scapulae/suprascapulae occur at the anterior portion of the rib cage, above the vertebral column and near the median plane. The adequacy of this position was tested using three-dimensional mechanical models of Felis, Rattus and Chamaeleo that assumed stances on a forelimb on a single side and the hindlimbs...

BACKGROUND: Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular disease in the general population. Although numerous treatments have been adopted for patients at different disease stages, no option other than amputation is available for patients presenting with critical limb ischaemia (CLI) unsuitable for rescue or reconstructive intervention. In this regard, prostanoids have been proposed as a therapeutic alternative, with the aim of increasing blood supply to the limb with occluded arteries through their vasodilatory, antithrombotic, and anti-inflammatory effects...

Background: Biomechanical predictors of a second anterior cruciate ligament (ACL) injury after ACL reconstruction (ACLR) and return to sport (RTS) have been identified; however, these measures may not be feasible in a standard clinical environment. Purpose/Hypothesis: The purpose of this study was to evaluate whether standard clinical measures predicted the risk of second ACL injuries. The hypothesis tested was that a combination of strength, function, and patient-reported measures at the time of RTS would predict the risk of second ACL injuries with high sensitivity and specificity...

Background: Many clinicians release patients to return to activity after anterior cruciate ligament reconstruction (ACLR) based on time from surgery despite deficits in muscle strength and function. It is unclear whether symmetry or unilateral performance is the best predictor of subjective outcomes after ACLR. Purpose: To determine physical performance predictors of patient-reported outcomes after reconstruction. Study Design: Cross-sectional study; Level of evidence, 3...

BACKGROUND: Deep enteroscopy-assisted ERCP (DEA-ERCP) in post-bariatric Roux-en-Y (RY) anatomy is challenging. Laparoscopy-assisted ERCP (LA-ERCP) or EUS-directed transgastric ERCP (EDGE) are technically easier and faster, but are more invasive and morbid procedures. Therefore, we have used DEA-ERCP as our first-line approach, reserving EDGE and LA-ERCP for cases in which adjunctive techniques that cannot be performed through an enteroscope are required (eg, EUS-FNA, SO manometry), or DEA-ERCP failures...

Understanding the morphogenesis and differentiation of tissues and organs from progenitor fields requires methods to visualize this process. Despite an ever-growing recognition that ECM plays an important role in tissue development, studies of ECM movement, and patterns in live tissue are scarce. Here, we describe a method in which a living limb bud is immunolabeled prior to fixation using fluorescent antibodies that recognize two ECM constituents, fibronectin and fibrillin 2. The results show that undifferentiated mesenchyme in quail embryos can be distinguished from prechondrogenic cellular condensations, in situ, via ECM antibodies-indicating the developmental transition from naïve mesenchyme to committed skeletal tissue...

BACKGROUND: Modules of muscle recruitment can be extracted from electromyography (EMG) during motions, such as walking, running, and swimming, to identify key features of muscle coordination. These features may provide insight into gait adaptation as a result of powered assistance. The aim of this study was to investigate the changes (module size, module timing and weighting patterns) of surface EMG data during assisted and unassisted walking in an powered, myoelectric, ankle-foot orthosis (ankle exoskeleton)...

BACKGROUND: Global brachial plexopathies cause major sensory and motor deficits in the affected arm and hand. Many patients report of psychosocial consequences including chronic pain, decreased self-sufficiency, and poor body image. Bionic reconstruction, which includes the amputation and prosthetic replacement of the functionless limb, has been shown to restore hand function in patients where classic reconstructions have failed. Patient selection and psychological evaluation before such a life-changing procedure are crucial for optimal functional outcomes...

Femorofemoral crossover bypass is a surgical arterial revascularization modality which is commonly performed for unilateral aortoiliac occlusive disease. It is primarily applied to patients with intermittent claudication or critical limb ischemia in whom underlying anatomic constraints rule out endovascular means of restoring in-line flow and those who do not qualify for anatomic reconstruction due to the comorbid conditions that preclude a more invasive open surgical approach. This surgical procedure may be also used as a complementary component of endovascular repair of abdominal aortic aneurysms when one aortoiliac arterial system is occluded to ensure exclusion of the aortic aneurysm...

Reconstruction of the defect following limb-sparing resection of malignant bone tumors is controversial and extremely challenging. Extracorporeal irradiation (ECI) and re-implantation have been used for limb salvage surgery for patients, with major advantages, including biological reconstruction, ready availability and preservation of bone stock, over replacement with a megaprosthesis. The purpose of the present study was to present our experience and details of all patients treated with this surgery. Between June 2005 and December 2014, we followed-up 23 patients with limb malignancies who were treated with en bloc excision followed by 50-Gy single dose ECI and re-implantation of involved bone segments...
