Active clinical trials for "Stomach Diseases"

The purpose of the study is to assess the efficacy, safety and usability of perioperative fully-automated closed-loop insulin delivery versus standard insulin therapy in patients with diabetes other than type 1 diabetes undergoing elective major abdominal surgery.

This is a single-arm, phase II study of camrelizumab combined with SOX regimen in subjects with resectable locally advanced gastric cancer. The patients will receive camrelizumab ,S-1 and oxaliplatin given every 3 weeks for 3 cycles as neoadjuvant therapy. After the surgery, adjuvant therapy which includes camrelizumab and SOX regimen will begin.

This is a single-institution, prospective phase II trial with an initial safety run-in to evaluate the efficacy and safety of neoadjuvant pembrolizumab combined with chemoradiotherapy and adjuvant pembrolizumab in patients with locally advanced esophageal and gastric cancers (EGC). Chemoradiation therapy (45Gy in 25 fractions with concurrent, weekly carboplatin [AUC 2] and paclitaxel [50mg/m2 of BSA]) with three cycles of pembrolizumab will be administered as neoadjuvant therapy. These patients will also receive three cycles of adjuvant pembrolizumab after surgical resection

Magnetically controlled capsule endoscopy (MCCE) is an outstanding opportunity for the painless endoscopic screening of the esophagus and stomach before small bowel examiantion. Further improvement in patients positioning might increase the esophageal transit time of the capsule endoscope and could improve the sensitivity and specificity of the esophageal MCCE investigation. Our present study aimed to compare the visualization of the esophagus (especially the Z-line) with different capsule swallowing protocols.

The purpose of this study is to evaluate the efficacy and tolerability of the maintenance treatment of Apatinib/Capecitabine after fluorouracil and platinum based first-line chemotherapy in advanced gastric cancer.

Rebound acid hypersecretion (RAHS), defined as an increase in gastric acid secretion above pre-treatment levels after PPIs therapy is observed within two weeks after withdrawal of treatment and could theoretically lead to acid-related symptoms such as heartburn, acid regurgitation, or dyspepsia that might result in resumption of therapy. A plausible physiologic theory for the rebound phenomenon suggests that long-term, elevated gastric pH caused by blockage of the proton-pumps stimulates compensatory gastrin release. Interestingly, Reimer et al. demonstrated the occurrence of RAHS in healthy volunteers who had received eight weeks of esomperazole. The clinical symptoms occured in a different prevalence compared with placebo treated patients at ten weeks after withdrawal and until the end of the study (twelve weeks). Twenty to twenty-two percent of patients displayed symptoms ten or twelve weeks after having discontinued PPIs while they occured in 1.7-7% of placebo-treated patients. Efforts should be pursued to restrict PPI therapy use to patients likely to benefit from it. In this context, we propose to investigate the benefit of a progressive decrease in doses of esomeprazole compared to a sudden discontinuation. This is a randomized, double-blind, placebo-controlled trial with 156 patients treated by esomeprazole 40mg since four weeks least, randomized to one week of placebo or one week of esomeprazole 20mg. We want to compare the prevalence of clinical gastrointestinal symptoms between patients with progressive discontinuation (one week of esomeprazole, 20mg, then discontinuation) or those with sudden discontinuation of esomeprazole 40mg.

Endoscopy is the diagnostic modality for most gastroduodenal diseases. During endoscopy mucus and foam may actually interfere with the visibility of the stomach mucosa. So the mixture of mucolytic ( N-acetyl cysteine) and anti-foaming agents ( simethicone) agents may disperse the bubbles and mucus in the stomach and enhance gastric visibility. This unique combination drink given 20-30 minutes prior to endoscopy is absolutely safe. There are previous studies from India, which was retrospective study. So, we have planned to conduct this randomized controlled trial on this issue. Adult patients undergoing diagnostic endoscopy will be randomized and one group (100 patients) will be given the combination drink whereas another group 9100 patients) will undergo an endoscopy after overnight fasting only, as a placebo drink may actually hamper the endoscopic visibility. Our primary outcome, gastric visibility will be assessed using a standard visibility scoring system.

The main purpose of this study is to evaluate clinical efficacy of bismuth tripotassium dicitrate (De-Nol) in combination with pantoprazole versus pantoprazole monotherapy in subjects with NSAID-induced gastropathy in 14±2 days of treatment.

The objective of this study is to observe gastric mucosal injuries in NSAID and non-NSAID users with magnetically-controlled capsule gastroscopy, and explore the effects of NSAIDs on gastric mucosal damage.

Number of patients with unsatisfactory pain relief defined as average visual analog scale (VAS) more than 5 with or without requirement of IVPCA for pain relief during the first 48 hours postoperative period will be compared between the two groups and form the primary outcome for the study. Postoperative pain intensity will be measured by Visual Analog Scale (VAS) with 0- being no pain and 10-being maximum pain and the analgesic efficacy in both groups will also be evaluated by the amount of total narcotic consumption (measured with IV morphine equivalent doses of analgesics used to provide pain relief).
