Filter by:Patients with colorectal polyps removed endoscopically (polypectomy, endoscopic mucosal resection, underwater endoscopic mucosal resection, endoscopic submucosal dissection) may experience delayed post polypectomy bleeding. The incidence is about one in 40 cases. There are risks factors for this complication, depending on the polyp type, patient demographics and co-morbidities and polypectomy technique. There are meta-analysis and nomograms for risk prediction available. We will try to predict delayed post polypectomy bleeding by using FIT (fecal immunochemical test), with a cut-off adapted to detect post polypectomy bleeding, administered daily for 2 weeks after polypectomy.
This study is intended to demonstrate the superiority of colorectal polyp detection using computer-assisted colonoscopy compared to conventional colonoscopy.
The purpose of this study is to evaluate the impact of implementing an integrated clinical care pathway for the diagnosis, referral, evaluation and treatment of large complex colorectal polyps on clinical outcomes
Colorectal cancer is the second most common cancer in Canada. Colonoscopy and removal of precancerous polyps (polypectomy) reduces the incidence and mortality associated with colorectal cancer. However, polypectomy is associated with adverse events. Post-polypectomy bleeding has a significant impact on the life of the patient as it can require hospitalization, transfusions, repeat colonoscopy and rarely death. It is also a substantial cost to the health care system. There currently is no standard of care to prevent bleeding after polypectomy. Tranexamic acid reduces fibrinolysis by slowing down the conversion of plasminogen to plasmin which may prevent bleeding. Although this medication is used extensively for other purposes, it has not been studied before to prevent post-polypectomy bleeding. This pilot study will examine factors involved in the feasibility of conducting a large-scale randomized controlled trial (RCT). This pilot study will include 25 consecutive patients who are treated with tranexamic acid after endoscopic mucosal resection (EMR) of large non-pedunculated colorectal polyps (LNPCP's) to prevent PPDB.
There is no evidence to prove the impact of post-procedural diet on post-polypectomy bleeding (PPB) or delayed perforation. No relevant study has been conducted and it is yet to be determined if absolute diet is necessary for post-polypectomy patients, and the comparison between normal diet and absolute diet also remains unclear. Therefore, we carried out this randomized controlled study to evaluate and compare tthe clinical effect of different diets on post-polypectomy patients.
