Active clinical trials for "Peptic Ulcer"

The purpose of the investigators study is to investigate the factors associated with rebleeding in patients with peptic ulcer bleeding.

The aim of this study is to assess the role of portal hypertension of peptic ulcer disease in liver cirrhosis and chronic hepatitis.

This will be a multicenter prospective observational study carried out in China. The investigators will collect data in a pre-specified Case Report Form. Main data from each patient will include demographics, endoscopy classification, and both endoscopy and pharmacological treatments received by patients. Data from each patient will be prospectively collected from the day the patient is diagnosed as peptic ulcer bleeding by endoscopy and receives endoscopy treatment if the investigator thinks it is needed and up to 30 days afterwards. The proportion of peptic ulcer bleeding patients who are at high risk is the primary outcome variable. High risk is defined as the patients with endoscopy Forrest classification Ia to IIb. The rate and type of endoscopic treatment, the rate of successful endoscopy treatment, the re-bleeding rate and the endoscopic re-treatment rate in high risk peptic ulcer bleeding patients will be collected. The surgery rate and mortality rate in high risk and overall patient population will be calculated.

The objective of this study is to determine whether the finger tip images captured by the EPIC ClearView device, when analyzed via the ClearView software, produce a Response Scale that characterizes trends consistent with known diagnoses identified by medical doctors. Specifically, the investigators hypothesize that the organ system involving any of a series of known active diagnoses will be identified in the EPIC ClearView Response Scale report with the intention of providing potential triage capabilities.

The aim of this study is to study the natural history of the ulcer healing while on proton pump inhibitors (PPI) and the ulcer recurrence without acid suppression therapy of Non-steroidal Anti-inflammatory Drugs (NSAID), non-Helicobacter pylori (HP) bleeding ulcer patients.

The study is aimed to determine the potential of volatile marker testing for identification of gastrointestinal cancers (in particular - colorectal and gastric cancers), the related precancerous lesions in the stomach and colon. The study will be addressing the role of confounding factors, including lifestyle factors, diet, smoking as well as addressing the potential role of microbiota in the composition of exhaled volatile markers.

Despite advances in laparoscopic surgery for perforated peptic ulcer (PPU), intra-abdominal abscess (IAA) is recognized as one of the commonly reported complications with relation to the extent of infectious abdominal contamination. Herein, the investigators report their experience of laparoscopic surgery for PPU with/without peritoneal irrigation and discuss postoperative outcome. The investigators retrospectively examined the electronic medical records of the patients who underwent laparoscopic surgery for perforated peptic ulcer at a single medical center in Taiwan between January 2013 and August 2021. Retrospectively, the investigators would include those patients with clinical diagnosis of PPU who underwent emergent laparoscopic surgery. The patients with previous abdominal surgery, pathologic confirmed malignant ulcer perforation or concomitant ulcer bleeding were excluded. The investigators focused on post-operative complications and outcome after laparoscopic surgery with or without peritoneal irrigation. This information can be important in improving surgical options with respect to risk and potential benefits in this setting.

To investigate the adjunctive role of "Capsule Endoscope" in continuous endoscopic monitoring and early detection of recurrent ulcer bleeding after endoscopic therapy in patients presenting with bleeding peptic ulcers

The primary objective is to investigate the adverse events during upper gastrointestinal endoscopy with and without sedation in Chinese population

Helicobacter pylori (HP) is a gram-negative bacillus responsible for one of the most common infections found in humans worldwide. By the early-to-mid 1990s, further evidence emerged supporting the link between the chronic gastritis of HP infection and malignancy in adults, specifically gastric lymphoma and adenocarcinoma. The potential of HP eradication for the prevention of gastric cancer was underlined. At the national consensus meeting held in Brussels in 1998, HP eradication was strongly recommended in past or current peptic ulcer diseases, regardless of activity, complication and post endoscopic resection of early cancer. Some patients received gastric surgery due to the complications of peptic ulcer such as bleeding or perforation in the pre-HP eradication era. Their HP infection status was not surveyed and unknown at the time. Afterward, some of them were not suggested to receive an eradication therapy and recovered from the operative procedure. According to the consensus to treat HP for a purpose to reduce the risk of gastric cancer, these patients were still under risk. There have been only a few surveys on the prevalence of persistent HP infection in patients who have undergone surgery. The aim of the study was to evaluate the prevalence and histological features of HP infection after a time course of partial distal gastric surgery.
