Active clinical trials for "Gastrointestinal Diseases"

The objective of this study is to confirm the sensitivity and specificity of a stool DNA test for detection of colorectal cancer and pre-cancer.

Endoscopic submucosal dissection(ESD) is a prominent minimally invasive operation technique for treating early gastrointestinal tumor. But promoting ESD is uneasy because of its complications such as postoperative bleeding, perforation and so on. So if we decrease the rate of postoperative bleeding, ESD might be better popularized. Some study indicated that hypertension was the independent risk factor of postoperative bleeding. Endoscopic center of Fudan University Zhongshan Hospital is a rich experienced medical unit in doing ESD operation in China. Referring to our experience, if we can use some special methods to find the potential bleeding spot which is not obvious during ESD operation and we coagulate it precisely, then we may control the risk of postoperative bleeding. Based on the above hypothesis, our team designed this study to examine whether increasing blood pressure during gastric ESD could help to control the risk of postoperative bleeding.

The purpose of this study is to assess the feasibility of TrueLoo™, an Internet-connected smart toilet seat, in accurately monitoring and logging bowel movements and urinations of residents in senior living facilities across Northern California.

The Cohort of Swedish Men began in 1997, when all men born between 1918 and 1952 and residing in two counties in central Sweden received a questionnaire including about 350 items concerning diet and other lifestyle factors. A second questionnaire was sent out in 2008-09.

This study investigates distribution and regulation of bile acid transport in the human intestine.

The purpose of this study is to compare the efficiency of writing endoscopic reports by artificial intelligence and physicians through a randomized controlled trial.

The primary objective of this study is to gather stool samples from subjects with inflammatory bowel disease (IBD) to be added to a test set of stool samples that will be utilized to help select molecular markers and determine the optimal sensitivity and specificity values for the Exact IBD-ACRN surveillance test for colorectal cancer (CRC).

Prospective study so as to evaluate CONECCT score to determine both histological tissue and therapeutic choice

The Swedish Mammography Cohort began in 1987-1990, when 66,651 women living in two counties in central Sweden completed a mailed questionnaire that included items about their diet, parity, age at first child's birth, history of breast cancer in family, weight, height, and education. Follow-up questionnaires have been sent out in 1997 and in 2008-09.

By placing the medical record information of many subjects into a research registry, researchers will be able to conduct research studies directed at increasing our knowledge about Gastrointestinal Diseases.
