Surgical resection represents one of the essential cornerstones in multimodal treatment of malignant pleural mesothelioma. In cases of tumor infiltration of the lung, lung-scarifying procedures such as lobectomies or pneumonectomies might be necessary to achieve macroscopic complete resection. However, this increases the morbidity of the patients because it leads to possible delay of the planned chemotherapy or radiotherapy. Innovative surgical techniques are therefore required to enable salvage of the lung parenchyma and optimization of surgical treatment...

Craniomaxillofacial reconstructive surgery is a challenging field. First it aims to restore primary functions and second to preserve craniofacial anatomical features like symmetry and harmony. Three-dimensional (3D) printed biomodels have been widely adopted in medical fields by providing tactile feedback and a superior appreciation of visuospatial relationship between anatomical structures. Craniomaxillofacial reconstructive surgery was one of the first areas to implement 3D printing technology in their practice...

BACKGROUND: A bulla is a marked enlarged space within the parenchyma of the lung. Bullae may cause dyspnea by compressing healthy lung parenchyma and can cause a pneumothorax. Also, bullae are associated with malignancy, therefore surgical bullectomy is indicated on preventive basis. This case is unique and therefore valuable because of the remarkable presentation, innovative treatment and the spectacular improvement of lung function and socio-economic performance of the patient. CASE PRESENTATION: In this case report we describe the presentation, minimally invasive surgical treatment by means of a robot-assisted lobectomy and postoperative outcome of a young patient with a giant congenital bulla of the left upper lobe...

The modern clinical practice is characterized by intensive introduction of innovative technologies for improving treatment and diagnostic procedures, minimizing their impact on the patient, complications rate and economic reasons. One of the priorities in this area is both diagnostic and therapeutic endoscopy. The degree of practical use of innovative endoscopic technologies depends on not only the quality of care, but also their economic reasons. Endoscopic treatment has become the method of choice for gastrointestional bleeding, extraction of foreign bodies, obstructive jaundice, polyps of the gastrointestinal tract, achalasia, esophageal strictures, etc...

Articular cartilage injuries experienced at an early age can lead to the development of osteoarthritis later in life. In situ 3D printing is an exciting and innovative bio-fabrication technology that enables the surgeon to deliver tissue- engineering techniques at the time and location of need. We have created a hand- held 3D printing device (Biopen) that allows the simultaneous co-axial extrusion of bioscaffold and cultured cells directly into the cartilage defect in vivo in a single session surgery. This pilot study assesses the ability of the Biopen to repair a full thickness chondral defect and the early outcomes in cartilage regeneration, and compares these results to other treatments in a large animal model...

INTRODUCTION: Postmastectomy radiation therapy (PMRT) has known deleterious side effects in immediate autologous breast reconstruction. However, plastic surgeons are rarely involved in PMRT planning. Our institution has adopted a custom bolus approach for all patients receiving PMRT. This offers uniform distribution of standard radiation doses, thereby minimizing radiation-induced changes while maintaining oncologic safety. We present our 8-year experience with the custom bolus approach for PMRT delivery in immediate autologous breast reconstruction...

PURPOSE: To review the evolution of theories and practices concerning surgery for exotropia over the last approximately 200 years. METHODS: Major ophthalmology texts and relevant references were reviewed to discover experience and thinking concerning the causes of comitant intermittent and constant exotropia and corrective surgical approaches. RESULTS: The concept that excessive divergence is the cause of comitant exotropia has given way to one recognizing that this disorder is a position of rest modified by convergence...

PURPOSE OF REVIEW: Craniomaxillofacial trauma is one of the most complex clinical conditions in contemporary maxillofacial surgery. Vital structures and possible functional and esthetic sequelae are important considerations following this type of trauma and intervention. Despite the best efforts of the primary surgery, there are a group of patients that will have poor outcomes requiring secondary reconstruction to restore form and function. The purpose of this study is to review current concepts on secondary reconstruction to the maxillofacial complex...

Type II Abernethy malformations, characterized by side-to-side portosystemic shunting with preserved intrahepatic portal venous system, have been treated with shunt closure surgically and endovascularly. Three-dimensional printing has been used to develop highly accurate patient-specific representations for surgical and endovascular planning and intervention. This innovation describes three-dimensional printing to successfully close a flush-oriented type II Abernethy malformation, with discrepant dimensions on computed tomography, conventional venography, and intravascular ultrasound, using a 12-mm AMPLATZER atrial septal occluder device...

Although attempts to develop stereotactic approaches to intracranial surgery started in the late 19th century with Dittmar, Zernov, and more famously, Horsley and Clarke, widespread use of the technique for human brain surgery started in the second part of the 20th century. Remarkably, a significant similar surgical procedure had already been performed in the late 19th century by Gaston Contremoulins in France and has remained unknown. Contremoulins used the principles of modern stereotaxy in association with radiography for the first time, allowing the successful removal of intracranial bullets in 2 patients...

The treatment of biliary stenosis after pediatric LDLT is challenging. We describe an innovative technique of peripheral IHCJ for the treatment of patients with complex biliary stenosis after pediatric LDLT in whom percutaneous treatment failed. During surgery, the percutaneous biliary drainage is removed and a flexible metal stylet is introduced trough the tract. Subsequently, the most superficial aspect of the biliary tree is recognized by palpation of the stylet's round tip in the liver surface. The liver parenchyma is then transected until the bile duct is reached...

The admission of lung cancer patients to intensive care is related to postprocedural/postoperative care and medical complications due to cancer or its treatment, but is also related to acute organ failure not directly related to cancer.Despite careful preoperative risk management and the use of modern surgical and anaesthetic techniques, thoracic surgery remains associated with high morbidity, related to the extent of resection and specific comorbidities. Fast-tracking processes with timely recognition and treatment of complications favourably influence patient outcome...

Pavlos Ioannou performed an innovative surgical operation for breast cancer in Vienna University Hospital in 1861. A few years later, after his return to Greece, an operation performed on his closest friend's child, which led to fatal complications, led him to retire from surgical practice. William Halsted travelled to Europe in order to master European surgery, including at Vienna University, and about 20 years later he published his famous method for radical mastectomy, which appears to be identical to Ioannou's operation...

Knowledge of the physical characteristics of different laser lights and optical and thermal properties of oral tissues is very important to understand the interaction of dental lasers with biological tissues. Choosing the correct dental laser is crucial to match specific wavelengths with target chromophores of different tissues; this affinity makes laser irradiation selective and therefore minimally invasive. Various types of lasers are used in dentistry, offering a viable alternative to low and high-speed handpieces and surgical blades, and also minimising fear and discomfort of the patient...

Kenichi Nishiyama
An exoscope, high-definition video telescope operating monitor system to perform microsurgery has recently been proposed an alternative to the operating microscope. It enables surgeons to complete the operation assistance by visualizing magnified images on a display. The strong points of exoscope are the wide field of view and deep focus. It minimized the need for repositioning and refocusing during the procedure. On the other hand, limitation of magnifying object was an emphasizing weak point. The procedures are performed under 2D motion images with a visual perception through dynamic cue and stereoscopically viewing corresponding to the motion parallax...
