Filter by:The primary objective is to determine the sensitivity and specificity of the Exact Colorectal Cancer (CRC) screening test for colorectal cancer, using colonoscopy as the reference method. Lesions will be confirmed as malignant by histopathologic examination. The secondary objective is to compare the performance of the Exact CRC screening test to a commercially available FIT assay, both with respect to cancer and advanced adenoma. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.
This feasibility trial will evaluate the ability of the SuMO Tissue Access and Resection System (Apollo Endosurgery, Austin, Texas). The SuMO System utilizes balloons to create a submucosal pocket and electrosurgical cutting device to resect the mucosa. The SuMO elevates the tissue from the underlying muscularis using a balloon to distend the submucosa, similar to what is currently performed with injectable saline in a standard EMR. After dissection of the lesion, a separate cutting device will be utilized to resect the tissue by cutting around the border of the targeted tissue. If needed, a standard loop snare will be used to complete the mucosal resection.
It is hypothesized that primary care colonoscopists are able to achieve benchmarks in colonoscopy quality including cecal intubation and adenoma detection rates and serious adverse event rates. This prospective study is the first in depth analysis of the quality of colonoscopic procedures performed by primary care physicians at a provincial level in Canada. In addition, the APC Endo study is the first to directly examine both the quality of colonoscopy and patient satisfaction in the same study.
The objective of this study is to confirm the sensitivity of a stool DNA test for detection of colorectal cancer and pre-cancer. Another objective is to provide anonymous, clinically characterized specimens for a bio-repository for future colorectal cancer-related test development.
The Canadian College of Naturopathic Medicine is conducting a research study on Irritable Bowel Syndrome (IBS), a common condition in North America. It is a long term, recurring gastrointestinal disorder that is estimated to affect 30% of the general population. IBS is characterized by abdominal pain and cramps, and bowel dysfunction such as diarrhea and bloating. The medicines that are currently used to help people with IBS are not as effective as we would like them to be. These medicines are usually only prescribed to reduce the pain of IBS and not actually treat the disorder itself. Recently, scientists have found that probiotics (beneficial bacteria that live inside humans) may help reduce the painful symptoms and diarrhea that are part of IBS. This research is being conducted to determine whether this particular combination of three probiotic bacteria (named Lactobacillus gasseri, Bifidobacterium bifidum and Bifidobacterium longum) will reduce the symptoms of IBS.
The purpose of this study is to improve the investigators understanding of different training methods in laparoscopic colon surgery.
The standard treatment for post operative pain is now bupivacaine + sufentanil. The use of this combination during fast-track colonic surgery leads frequently to post-operative nausea and vomiting and limited mobilisation possibilities. Therefore the department anaesthesiology wants to evaluate the use of a different local anaesthetic: levobupivacaine combined with morphine on demand. The expectation is that the use of levobupivacaine leads to less side effects.
The purpose of this study is to determine: 1. What quantity of bacteria is spilled into the abdomen during a colon resection 2. If there is a correlation between the quantity and post-operative infection 3. What intralumenal pressure is generated when testing the colonic anastomosis for air leak
To evaluate the performance of PillCam COLON 2 in regards to detection of patients with polyps where colonoscopy is considered as the gold standard reference.
The research project addresses the following hypotheses (A) the normal balance of beneficial and detrimental commensal intestinal bacteria is deranged in IBS, with selective alterations in clinically defined patient subsets i.e., diarrhea predominant IBS (D-IBS) and post-infectious IBS (PI-IBS); (B) these changes in intestinal microflora are associated with sub-clinical mucosal inflammation and activation of the mucosal immune system; and (C) activation of the mucosal immune system leads to alterations in gastrointestinal (GI) functions (i.e., motility and sensation) and functional symptoms.
