INTRODUCTION: After laparoscopic cholecystectomy, laparoscopic fundoplication has become another gold standard of minimal invasive surgery. The level of satisfaction of patients undergoing endoscopic surgery is almost 90%. Laparoscopic fundoplication, like other surgery methods, can also be burdened with grave complications, which could result in a fatal outcome even if the surgery is performed by a skilled surgeon. Even the authors themselves encounter complications despite their rich experience (more than 3,500 laparoscopic operations in the diaphragmatic hiatus area in more than 20 years)...

The aim of this study was the development of novel fluorescent microspheres as embolic agent for transarterial embolization (TAE) of advanced stages of hepatocellular carcinoma (HCC). TAE is a minimally invasive procedure that induces tumour regression blocking the blood flow by injection of microparticles. The microspheres currently used in clinical application cannot be visualized in vivo. Surgeon could exploit the intraoperative detection of embolic agents during resection of the malignant mass. Biocompatible indocyanine green (ICG)-loaded microspheres (CAB-CS-ICG) were prepared using a multi-step method...

Nanoparticles (NPs) are potential drug delivery vehicles for treatment of a broad range of diseases. Intravenous (IV) administration, the most common form of delivery, is relatively non-invasive and provides (in theory) access throughout the circulatory system. However, in practice, many IV injected NPs are quickly eliminated by specialized phagocytes in the liver and spleen. Consequently, new materials have been developed with the capacity to significantly extend the circulating half-life of IV administered NPs...

BACKGROUND: The use of dermal fillers in minimally invasive facial aesthetic procedures has become increasingly popular of late, yet as the indications and the number of procedures performed increase, the number of complications is also likely to increase. Paying special attention to specific patient characteristics and to the technique used can do much to avoid these complications. Indeed, a well-trained physician can also minimize the impact of such problems when they do occur. METHODS: A multidisciplinary group of experts in aesthetic treatments reviewed the main factors associated with the complications that arise when using dermal fillers...

BACKGROUND: People with heart failure and preserved ejection fraction develop increases in left ventricular (LV) end-diastolic pressures during exercise that contribute to dyspnea. In normal open-chest animal preparations, the pericardium restrains LV filling when central blood volume increases. We hypothesized that resection of the pericardium using a minimally invasive epicardial approach would mitigate the increase in LV end-diastolic pressure that develops during volume loading in normal and diseased hearts with the chest intact...

BACKGROUND: Noninvasive external volume expansion device has been applied to stimulate nonsurgical breast enlargement in clinical settings. Although previous results demonstrate the capacity of external volume expansion to increase the number of adipocytes, this strategy alone is insufficient to reconstruct soft-tissue defects or increase breast mass. The authors combined a minimally invasive tissue dissection method with external volume expansion to generate large volumes of adipose tissue...

Ultrathin veneer is a new therapeutic technology developed from minimally invasive theories. Ultrathin veneer alters the unwanted shape and color of a tooth through minimal or lack of preparation. The color of tooth after restoration is mixed with the natural color of tooth, the original color of veneer, and the color of bonding material because of ultrathin (approximately 0.2 mm) veneer. Thus, the color is affected by numerous variations. Full considerations are required for creating designs. The author summarizes clinical points and provides suggestions for ultrathin veneer in color...

SURGICAL TECHNIQUES: In the HerniaSurge guidelines the highest evidence is found with respect to recommendations for mesh-based surgery techniques. This includes Lichtenstein as well as the minimally invasive TEP/TAPP surgery. For discreet symptomatic or asymptomatic inguinal hernia, watchful waiting is an option if the state of health and social situation are taken into account; however, femoral hernia should be treated promptly with a mesh technique, with laparoendoscopic techniques being the more favored option...
