Adenocarcinoma of the esophagogastric junction (AEG) still represent a certain surgical challenge. In contrary to the trend of thoracoabdominal surgery for AEG I and AEG II cancer, the proximal gastrectomy is regaining popularity through new reconstruction methods such as the double tract reconstruction. Proximal gastrectomy followed by double tract reconstruction represents an alternative for the thoracoabdominal approach for suitable AEG II cancer and an alternative to the total gastrectomy for AEG III cancers. Latest studies suggest a functional benefit of proximal gastrectomy and double tract reconstruction in comparison to total gastrectomy. The accurate indication for proximal gastrectomy for locally advanced cancers has to be established in the near future as well as the influence of the size of the remnant stomach on the outcome, as Asian techniques for early lesions sometimes significantly differ from European. The following article reflects the present evidence on proximal gastrectomy and double tract reconstruction as well as technical aspects in the context of cancer of the esophagogastric junction.

Growth and remodeling of the cardiac outflow tract (OFT) is poorly understood but associated with serious congenital heart defects (CHD). While only a minority of CHDs have identifiable genetic causes, the functional roles of mechanical forces in OFT remodeling are far less characterized. A key barrier has been the lack of longitudinal investigations examining the interplay between dynamic blood flow and wall motion across clinically relevant stages.

Materials and methods: The tensile strength of different types of anastomoses was compared ex vivo using porcine esophagus, stomach, and small intestine. The test setup included a tensile testing device, which applied a controlled force on the anastomoses until they broke, which was recorded for each type of anastomosis and was expressed in N.

Background: Total gastrectomy and proximal gastrectomy (PG) are both treatment options for proximal gastric cancer. Currently, there is no consensus on which procedure is better. The aim of this study was to compare the operative outcomes between proximal gastrectomy and total gastrectomy in the treatment of proximal gastric cancer.

A biofilm is a community of microorganisms adhered to a surface, bound together by extracellular polymeric substances (EPS). They are ubiquitous in nature and develop on a range of surfaces including living tissue. Biofilms themselves typically do not negatively affect their host, but under certain conditions they can retain pathogenic features and cause a wide range of illnesses including persistent or chronic infections.

Current treatments fall short in managing allergic rhinitis (AR), emphasizing the need for additional strategies. Beneficial bacteria application shows promise in AR; however, most studies focus on oral probiotic administration without monitoring the applied strains in the upper respiratory tract (URT) and their local effects. In this randomized, double-blind, placebo-controlled trial, the probiotic GG was administered via chewable tablets in seasonal AR patients, randomized to probiotic ( = 33) or placebo ( = 31) groups.
