Filter by:The purpose of this study is to determine if screening colonoscopy performed on adults with the water exchange method, as opposed to the air method, will have a higher adenoma detection rate.
Digital rectal examination is an act clinically performed daily by physicians and surgeons. It remains the key diagnostic test and directs the therapeutic management of cancer of the lower and middle rectum. It can be done in two main positions: lateral decubitus, and supine. However, no randomized study in colorectal surgery is not interested in evaluating the best position to perform a full rectal exam.
A study to assess the pharmacodynamics, safety and tolerability of a PEG-based bowel cleansing solution (MOVIPREP®)
The purpose of this research study is to evaluate if a negative-pressure dressing placed over a surgical incision can reduce the risk of developing a surgical site infection compared to a commonly-used sterile gauze incision dressing. In this study, the negative-pressure dressing will be compared to a standard post-surgical sterile gauze dressing. In this study patients will either receive a negative-pressure dressing or a standard sterile gauze dressing
The investigators propose a screening population-based study to systematically evaluate the accuracy and clinical relevance of sDNA testing as a potential alternative to colonoscopy screening. In addition, the investigators propose a genetic epidemiologic study of the relation between colon polyps, an established precursor of colon cancer, and two factors that may influence risk for colon cancer: candidate genes and diet.
In this research study, investigators use colonoscopy as a case example to evaluate a predictive overbooking model derived using patient-level predictors of absenteeism. The no-show overbooking intervention employs a logistic regression model that uses patient data to predict the odds of no-showing with 80% accuracy. These projected no-show appointments will be overbooked by clerks for patients who agree to join a "fast track" short-call line. By rapidly processing endoscopy patients and moving them out of traditional slots, investigators predict more scheduling slots would become available for patients awaiting colonoscopy.
Patients are invited to participate in a research study of liver perfusion (how blood flows to the liver over time). Researchers hope to learn whether perfusion characteristics of liver metastases may be predictive of response to treatment and whether liver perfusion characteristics can be used to follow response to treatment. Patients were selected as a possible participant in this study because they are identified as having liver metastases
The objective of this trial is to define the rate of upstaging of colon carcinoma lymph node metastasis with sentinel lymph node (SLN) mapping. Null hypothesis: There is no difference in the rate of lymph node metastasis between conventional histopathological processing of lymph nodes and SLN mapping with detailed pathologic examination using immunohistochemistry (IHC) in patients undergoing resection of colon carcinoma.
The clinical benefit of resection of the primary tumour in patients with synchronous unresectable metastases is not known. In the literature studies usually describe retrospective selected patients with synchronous metastases treated with or without resection of the primary tumour. All these studies are biased in patient selection and there are no prospective randomized studies on this topic. In patients with few or absent symptoms of the primary tumour, arguments both in favour and against initial resection have been presented, and therefore a randomized trial is warranted. Although recent publications suggest that resection of the primary tumour in synchronous metastasized colon cancer patients might not be necessary, this appears to be based on feasibility and not on clinical outcome. Several studies comparing large groups of patients with or without resection of the primary tumour suggest an improved survival when the primary tumour is resected. A potential benefit of resection of the primary tumour is to prevent complications of the primary tumour during chemotherapy treatment or during later stages of the disease. A recent analysis of the CAIRO and CAIRO2 data showed that metastatic colon cancer patients who had a resection of the primary tumour prior to study entry, had an improved survival compared to patients without a resection of the primary tumour. However, these patients were selected after the primary tumour was resected and therefore these results are not corrected for surgical morbidity and mortality. The investigators here propose a randomized trial in order to demonstrate that resection of the primary tumour does improve overall survival.
The investigators research mobilizes the resources of an integrated health-delivery system with extensive electronic clinical data to implement and evaluate a new strategy to maximize screening of Colorectal Cancer (CRC) patients for Lynch Syndrome.
