Filter by:The purpose of this study is to find out whether treatment with trastuzumab combined with pembrolizumab will improve the clearance of tumor DNA from participants' bodies after surgery.
The purpose of this study is to determine whether the newly constructed CE (Conformité Européenne) marked drill biopsy instrument for flexible endoscopes can make possible representative biopsies of the increasing numbers of submucosal tumours in the gastrointestinal tract. The amount of submucous tissue ( micrograms and in % of all the biopsy) harvested with the new drill biopsy instrument used in flexible endoscopy investigations is measured in the study and compared to the amount of submucous tissue harvested with the existing biopsy forceps.
The accurate prediction of depth of tumor invasion in early gastric cancer is essential for the proper selection of candidates for endoscopic resection. Conventional endoscopy and endoscopic ultrasonography have been useful diagnostic method for depth of invasion in early gastric cancer. However, there has been no prospective comparative study on the accuracy between the 2 methods. Therefore, the investigators prospectively compare the accuracy between the 2 methods regarding prediction of depth of invasion.
The aim of this study is to assess the effect of postoperative parenteral fish oil on clinical outcome and immune function after major laparoscopic abdominal surgery.
The purpose of this study is to determine if fine needle aspiration or fine needle biopsy is more efficacious and cost-effective than the other while maintaining diagnostic accuracy in the setting of solid gastrointestinal lesions.
The purpose of this study is to find out more about differences of the quality of life in patients undergoing Roux-En-Y pouch reconstruction and conventional Roux-En-Y reconstruction. To find a better reconstruction for patients who received total gastrectomy.
Insufflation is essential procedure to observe the lumen of gastrointestinal tract in gastroscopy or colonoscopy Currently, most of hospital in Korea are using room air for insufflation According to recent clinical studies have shown that carbon dioxide have better safe and reduce stomachache than room air when endoscopy and endoscopic procedure is performed. However, there was still no research data or study in Korea. In this study, the investigators will try to make comparison between Carbon dioxide and room air insufflation for endoscopic submucosal dissection for Gastric Tumor and investigate the efficacy and safety
The purpose of this study is to determine whether Helicobacter pylori eradication could reduce the new tumor development after endoscopic resection of gastric tumor.
