Filter by:Prophylactic use of anastomotic drain in upper gastrointestinal surgery has been questioned in the last 15 years but only small studies have been conducted. In 2015 a Cochrane meta analysis on four Randomized Controlled Trials (RCT) concluded that there was no convincing evidence to the routine drain placement in gastrectomy. Nevertheless the Authors evidenced the moderate/low methodological quality of the included studies and highlighted how 3 out of four came from Eastern countries. Despite the above mentioned limits, Enhanced Recovery After Surgery (ERAS) society published the guidelines for gastrectomy that strongly recommend, with high evidence level, to avoid routine use of drain in gastric surgery. After 2015 some other retrospective studies have been published, all with inconsistent results. Our objective is to perform a multicentre prospective trial in a large western cohort of patients to establish wether avoid routine use of anastomotic drain does not led to an increasing of postoperative invasive procedure.
This study aims to compare efficacy and safety of bismuth-containing quadruple therapy（with rabeprazole amoxicillin clarithromycin）of different kinds of bismuth（Bismuth potassium citrate, pectin bismuth capsules, pectin bismuth particles）in H. pylori first-line eradication. It is hypothesized that different bismuth containing quadruple therapies have comparable eradication efficacy and safety. Patients with confirmed H. pylori positive status will be randomized to one of the treatments described above. At week 2and 6 follow-up visits, a urea breath test(UBT) will be performed to confirm eradication.
This study evaluated the safety and efficacy of VE800 in combination with nivolumab in patients with selected types of advanced or metastatic cancer
The primary purpose is to compare the remifentanil requirements in deep vs moderate neuromuscular blocks during the surgical pleth index -guided anesthesia in patients undergoing laparoscopic gastrectomy.
Potential patients will be recruited at participating sites based on routine care with clinical indications for upper endoscopy. Following informed consent, patients will undergo their scheduled endoscopy with standard forceps biopsies along with the transepithelial brush samples. All samples, biopsy and brush samples, will be sent for pathology analysis, per standard clinical practice.
The investigators also aim to use our previously described quantifying method (q-ICG), to evaluate changes in gastric perfusion, during resection of cancer in the gastroesophageal junction (GEJ) and if a change in the operative technique influences microvascular flow in the gastroesophageal (GE) anastomosis.
This study evaluates the combination of bavituximab and pembrolizumab in the treatment of gastric and gastroesphogeal cancer. All patients will receive both bavituximab, a drug that is not yet approved by the FDA, and pembrolizumab known as Keytruda. There is no expanded access program available for the investigational agents per this protocol.
In this study patients will be offered intraperitoneal atomized chemotherapy as a supplement to the standard treatment of high-risk gastric cancer (laparoscopic removal of the stomach). Two commercially available oncologic drugs will be used (doxorubicin and cisplatin).
Title: A single-center, retrospective randomized controlled trial of artificial intelligence (AI) versus expert endoscopists for diagnosis of gastric cancer in patients who underwent upper gastrointestinal endoscopy. Précis: this single-center, retrospective randomized controlled trial will include 500 outpatients who underwent upper gastrointestinal endoscopy for gastric cancer screening and will compare the diagnostic detection rate for gastric cancer of AI and expert endoscopists. Objectives Primary Objective: to evaluate the diagnostic detection rate for gastric cancer of AI and expert endoscopists. Secondary Objectives: to determine whether AI is not inferior to expert endoscopists in terms of the number of images analyzed for diagnosis of gastric cancer and intersection over union (IOU), and the detection rate of diagnosis of early and advanced gastric cancer. Endpoints Primary Endpoint: diagnosis of gastric cancer. Secondary Endpoints: image based diagnosis of gastric cancer and IOU. Population: in total, 500 males and females aged ≥ 20 years who underwent upper gastrointestinal endoscopy for screening of gastric cancer at a single hospital in Japan. Describe the Intervention: AI-based diagnosis of gastric cancer based on upper gastrointestinal endoscopy images. Study Duration: 3 months.
This is an international multi-center randomised controlled study comparing outcomes of gastric endoscopic submucosal dissection (ESD) with or without addition of epinephrine in the submucosal injection solution.
