Polymorphism of Gene in Vietnamese Gastric Cancer Patients: A Multicenter Case-Control Study.

Background: A few studies revealed that the polymorphisms of gene have a role and significance as a susceptible factor contributing to gastric cancer. To better understand the roles of two genotype polymorphisms of rs4072037 and rs2070803 in the development of gastric cancer in Vietnamese population, a multicenter, large-sample, case-control study was conducted to investigate the potential association of these single-nucleotide polymorphisms (SNPs) of gene with gastric cancer risk and to evaluate the combination factors in relation with these SNPs.

Methods: This case-control study included 302 gastric cancer patients and 304 controls at four national medical hospitals between 2016 and 2018.

Totally Endoscopic Resection of Giant Left Atrial Myxoma Without Robotic Assistance.

There was no report on the application of totally endoscopic surgery for giant atrial myxoma resection. A 62-year-old female patient with giant atrial myxoma causing severe mitral stenosis and acute pulmonary edema underwent a successful operation by totally endoscopic techniques without the assistance of robotic systems using four small trocar ports (three 5-mm trocars and one 12-mm trocar). The patient recovered uneventfully and was satisfied with cosmetic results.

Totally Endoscopic Cardiac Surgery for Atrial Septal Defect Repair on Beating Heart Without Robotic Assistance in 25 Patients.

Objective: The aim of the study was to investigate the effectivity and safety of totally endoscopic cardiac surgery without robotic assistance for atrial septal defect (ASD) closure on beating hearts.

Methods: Twenty-five patients (adults/children: 15/10) underwent ASD closure using nonrobotically assisted totally endoscopic approach on beating heart. Three 5-mm trocars and one 12-mm trocar were used, only the superior vena cava is snared, filling the pleural and pericardial cavities with CO2, and the heart was beating during the surgery.
