Meta-analysis of studies comparing single-incision laparoscopic appendectomy and conventional multiport laparoscopic appendectomy
There is no consensus that single-incision laparoscopic appendectomy (SILS-A) is on a par with conventional multiport laparoscopic appendectomy (CMLA). The aim of this meta-analysis was to assess feasibility, safety, and potential benefits of SILS-A when compared with CMLA.Extracorporeal membrane oxygenation for resuscitation of deceased cardiac donor livers for hepatocyte isolation
Deceased cardiac donors (DCDs) have become a useful source of organs for liver transplantation; nevertheless, there are concerns about the longevity of these grafts. The aim of this study was to evaluate the use of extracorporeal membrane oxygenation (ECMO) to resuscitate DCD porcine livers as a preclinical model using hepatocyte isolation and viability as a marker to assess whole-graft preservation.Pterostilbene and Cancer: Current Review
Pterostilbene (trans-3,5-dimethoxy-4-hydroxystilbene) is an antioxidant that is primarily found in blueberries. Studies suggest that pterostilbene exhibits the hallmark characteristics of an effective anticancer agent based on its antineoplastic properties in several common malignancies. In vitro models have shown that pterostilbene inhibits cancer growth through alteration of the cell cycle, induction of apoptosis, and inhibition of metastasis. In vivo, pterostilbene inhibits tumorigenesis and metastasis with negligible toxicity.The Role of Hyaluronic Acid in Atherosclerosis and Intimal Hyperplasia
Atherosclerosis is a chronic inflammatory condition of the blood vessel wall that can lead to arterial narrowing and subsequent vascular compromise. Although there are a variety of open and endovascular procedures used to alleviate the obstructions caused by atherosclerotic plaque, blood vessel instrumentation itself can lead to renarrowing of the vessel lumen through intimal hyperplasia, wound contracture, or a combination of the two. While the cell types involved in both atherosclerosis and vessel renarrowing after surgical intervention are largely characterized, current research has shown that components of the extracellular matrix are also important in the pathogenesis of the aforementioned processes.Methods and Tools for Objective Assessment of Psychomotor Skills in Laparoscopic Surgery
Training and assessment paradigms for laparoscopic surgical skills are evolving from traditional mentor–trainee tutorship towards structured, more objective and safer programs. Accreditation of surgeons requires reaching a consensus on metrics and tasks used to assess surgeons’ psychomotor skills. Ongoing development of tracking systems and software solutions has allowed for the expansion of novel training and assessment means in laparoscopy. The current challenge is to adapt and include these systems within training programs, and to exploit their possibilities for evaluation purposes.Oxidative Stress in Laparoscopic Versus Open Abdominal Surgery: A Systematic Review
Any form of trauma, including surgery, is known to result in oxidative stress. Increased intra-abdominal pressure during pneumoperitoneum and inflation-deflation may cause ischemia reperfusion and, hence, oxidative stress may be greater during laparoscopic surgery. The aim of this study was to systemically review the literature to compare oxidative stress in laparoscopic and open procedures.Burn Scar Assessment: A Systematic Review of Different Scar Scales
Scars can be devastating and disfiguring, because they are clearly visible, stigmatizing, and permanent reminders of the initial accident or surgical event. Yet, there is still no consensus about the optimal scale or tool to assess the characteristics and evolution. Our aim was to evaluate the clinical importance of scar scales specifically developed for burn scars.
