BACKGROUND: In unstable trochanteric fractures, the extramedullary rotationally stable screw-anchor (RoSA) combines the benefits of the load and rotational stability of the blade with the advantages of the screw (pull-out resistance, compression capability) in a single load carrier, and was designed to prevent femoral neck shortening by using an additional locked trochanteric stabilizing plate (TSP). OBJECTIVES: The aim of the current prospective cohort study was the clinical evaluation of the RoSA/TSP system regarding the mechanical re-operation rate and the amount of postoperative femoral neck shortening...

Recurrent pyogenic cholangitis (RPC) is an infective process involving the biliary tree typified by pigmented intraductal calculi with dilatation of the intra- and extrahepatic biliary tree. Previously endemic to South-east Asia, RPC can now be seen in Western countries with the increasing access to international travel and immigration. Affected patients are often plagued by recurrent bouts of cholangitis, and commonly suffer from complications such as abscess formation and biliary strictures. In severe cases, cirrhosis with portal hypertension may develop...

The intrathecal space has become an important anatomic site for medical intervention not only in anesthesia practice, but also in many other medical specialties. Undesired/inadvertent intrathecal injections (UII) are generally rare. There is tremendous variation in reported inadvertent administrations via an intrathecal route in the literature, mainly as individual cases and very small case-series reports. This review aims to identify potential sources of UII, its clinical presentations, and appropriate management...

We present a case of a 41-year-old man with symptomatic pulmonary cement embolism following percutaneous vertebral augmentation, which was successfully retrieved via a percutaneous endovascular approach, a novel technique with only two prior cases reported. Cement leakage, including venous embolization of cement into the cardiopulmonary circulation, is a known potential complication following percutaneous kyphoplasty and vertebroplasty. While many patients with pulmonary cement embolism are asymptomatic and likely go undiagnosed, others experience respiratory distress and hemodynamic compromise requiring surgical and medical intervention...

BACKGROUND: The portal vascularization of segment IV (S4) of the liver has not been well described. Knowledge of the portal supply to S4 is of great interest for liver surgery and for interventional radiological procedures. This study aimed to analyse the distribution of portal vein branches supplying S4. METHODS: We retrospectively analysed data from patients operated on for liver tumours between 2007 and 2016. Patients with involvement of S4 branches or the left portal vein, previous liver surgery or poor quality imaging were excluded...

INTRODUCTION: Penetrating oesophageal injuries are extremely rare. Their timely recognition can be difficult and optimal treatment remains controversial. Early recognition of injury is possible with the help of a high index of suspicion and early radiological and endoscopic examinations. Prompt surgical intervention with primary repair of injury, should be the goal. PRESENTATION OF CASES: We describe two cases of penetrating oesophageal trauma where T-Tube placement through the oesophageal defect, was successfully employed...

Renal denervation (RDN) was reported as a novel exciting treatment for resistant hypertension in 2009. An initial randomized trial supported its efficacy and the technique gained rapid acceptance across the globe. However, a subsequent large blinded, sham arm randomized trial conducted in the USA (to gain Food and Drug Administration approval) failed to achieve its primary efficacy end point in reducing office blood pressure at 6 months. Published in 2014 this trial received both widespread praise and criticism...

Crohn's disease and ulcerative colitis are heterogeneous inflammatory bowel disease (IBD), and therapeutic requirements vary among patients. We have a limited capacity to predict disease progression for individual patients, so it is important that they are evaluated for presence of active disease when symptoms are mild or even absent, when patients are more likely to respond to new treatment interventions. It is then important to monitor responses to treatment, to quickly identify those therapies that are ineffective, modify or change therapy, and avoid disease complications...

BACKGROUND/AIM: Over the past two decades, several advances have been made in the management of patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT). Yttrium-90 ( 90 Y) radioembolization has recently been made a treatment option for patients with HCC and PVTT. However, there is still a need to systematicly evaluate the outcomes of 90 Y radioembolization for HCC and PVTT. We aimed to assess the safety and effectiveness of 90 Y radioembolization for HCC and PVTT...

Smooth muscle tumors (SMTs) of the pleura are exceptionally rare. At present and to the best of these authors' knowledge, there are only 17 cases reported in the literature. We describe a case of a 51-year-old woman who complained of left sided pleuritic chest pain. Further, computed tomography (CT) revealed a left sided localized pleural-based mass involving the 9th rib. She underwent an interventional radiology guided percutaneous core biopsy of the lesion, which disclosed a "Smooth Muscle Tumor of Undetermined Malignant Potential (SMT-UMP)...

Colorectal liver metastasis (CRLM) is the most frequent indication for liver resection in many centers. Recent improvements in oncology, surgery, interventional radiology, pathology and anesthesiology allow curative treatment in a larger proportion of patients with CRLM. Areas covered: We illustrate the various aspects of the management of CRLM through 11 questions that summarize the topic, from the current obtained survival to future perspectives such as transplantation. The limits of a curative treatment are also presented from different angles, such as the benefits of pathology, the surgical options for extreme resections, the available chemotherapies and their efficacy, or the non-surgical ablative treatments...
