Dear Editor, A 75-year-old woman living in a nursing home presented with a 24-hour history of abdominal cramping and vomiting. Medical history was remarkable for dementia and a percutaneous endoscopic gastrostomy (PEG) was performed 3 years earlier. The day before the admission the feeding tube was accidentally pulled out and a Foley catheter was placed in order to avoid stoma closure. On physi...

BACKGROUND Until the early 1980s, Stamm technique was considered standard method to gastrostomy. After description of the endoscopic technique, due to its efficiency and speed, quickly became the method of choice for long-term enteral access. AIM Describe a technique that combines direct view of the stomach from open surgery with the simplicity and less traumatic endoscopic gastrostomy method...

Aim To explore the expression and clinical significance of long noncoding RNA (lncRNA) gastric cancer-associated transcript 3 (GACAT3) in human colorectal cancer (CRC). Methods Expression of GACAT3 in CRC tissues and cell lines was measured using quantitative real-time PCR. CCK-8 and colony formation assays were used to assess the effect of GACAT3 on CRC cell line proliferation. Transwell inv...

Postesophagectomy gastric outlet obstruction occurs in 20%–30% of patients who undergo esophagectomy and is associated with significant morbidity and delayed recovery [1]. Recently, endoscopic pyloromyotomy, also called gastric peroral endoscopic myotomy (POEM), has been reported, in pigs and in a patient with refractory diabetic gastroparesis [2, 3]. We report a case of postesophagectomy delay...

BACKGROUND Our previous research results showed that Type II cGMP dependent protein kinase (PKG II) could block the activation of epidermal growth factor receptor (EGFR) and consequently inhibit the proliferation and the related MAPK/ERK-mediated signal transduction of gastric cancer cell line BGC-823, suggesting that PKG II might inhibit other EGFR-triggered signal transduction pathways and re...

AIM There is still no consensus about the optimal surgical approach for esophageal replacement in the case of long-gap esophageal atresia (LGEA) or extensive corrosive strictures. The aim of this article was to perform a meta-analysis comparing the most widely used techniques for esophageal replacement in children: jejunal interposition (JI), colon interposition (CI), and gastric pull-up (GPU)....

In this paper, the pull-in instability of piezoelectric polymeric nanocomposite plates reinforced by functionally graded single-walled carbon nanotubes (FG-SWCNTs) based on modified strain gradient theory (MSGT) is investigated. Various types of SWCNTs are distributed in piezoelectric polymeric plate and also surface stress effect is considered in this research. The piezoelectric polymeric nano...

introduction: to evaluate the effects of using sodium hypochlorite irrigant on pull-out bond strength of self-etch and self-adhesive resin cements to dentin. methods: sixty intact premolars were decoronated and the root canals were prepared by step-back technique. the teeth were divided into two groups according to the irrigant used during root canal treatment: 5.25% sodium hypochlorite and nor...
