Low Tie Versus High Tie of the Inferior Mesenteric Vein During Colorectal Cancer Surgery: A Randomized...
Anastomotic LeakAnastomotic Leak Large Intestine6 moreThis study aim to determine if a different surgical technique could result in a lower anastomotic leak rate. The two techniques are equally used around the world and well described by the international literature but this is the first study that compare the two techniques.
ICG Fluorescence Guided Lymph Node Mapping for Determination of Bowel Resection Margins in Colon...
Colon CancerThe study is aimed at investigating feasibility of defining colon resection margins for colon cancer with ICG by comparing lymphatic distribution of subserosally injected dye with actual spread of lymphatic metastases reported by pathologists after specimen examination
Tranexamic Acid During Colonic Endoscopic Resection Procedures
Colon NeoplasmColonoscopy with polypectomy reduces the incidence and mortality associated with colon cancer. However, polypectomy is associated with adverse events such as bleeding. Tranexamic acid (TXA) is a synthetic derivative of lysine that exerts antifibrinolytic effects and may prevent bleeding. The investigators aim to evaluate the effect of local TXA on preventing intraprocedural and postprocedural bleeding in patients undergoing endoscopic mucosal resection (EMR) of large colon polyps.
Xian-Lian-Jie-Du Optimization Decoction as an Adjuvant Treatment for Prevention of Recurrence of...
Colon CancerThis study is designed as a multi-center, randomized, double-blind, placebo-controlled trial. Subjects in the intervention group will be treated with XLJDOD compound granule. Subjects in the control group will be treated with placebo (XLJDOD mimetic agent).
Artificial Intelligence for Leaving in Situ Colorectal Polyps.
Colonic NeoplasmsThis two parallel-arms, randomized, multicenter trial is aimed at investigating safety and effectiveness of a Computer-Aided-Diagnosis (CADx)-assisted leave-in-situ strategy (Leave-In-Situ Arm) as opposed to a resect-all strategy (Standard Arm) as implemented by endoscopists in a real-world setting. With this study it will be possible to understand the impact of CADx in patient treatment and management both in terms of clinical outcome and costs.
Adjuvant mFOLFIRINOX for High-risk Stage III Colon Cancer
Colon Cancer Stage IIIA multicenter, open labeled randomized, phase II trial comparing mFOLFIRINOX and mFOLFOX6 as adjuvant treatment for high risk stage III (pT4N1/2 or pTanyN2) colon cancer
Carbon Black Tattoo in Colon Cancer
Endoscopic Tattoo of Suspected Colon CancerThe study is designed to elucidate whether carbon black suspension endoscopic tattoo enhances visibility of lymph nodes or tumor tissue on dissection of colonic surgical specimen, thereby making improvement in staging defined as better pTNM stage via better visualisation of carbon marked metastatic or sentinel lymph nodes or marked primary tumor or adjacent tissues.
IBD Neoplasia Surveillance RCT
Colonic NeoplasmsInflammatory Bowel Diseases1 moreWe will conduct a multicenter, parallel-group, non-inferiority RCT in persons with IBD undergoing colorectal neoplasia screening with high-definition white light colonoscopy, comparing a strategy of sampling visible lesions alone to a conventional strategy of sampling both visible lesions as well as normal-appearing mucosa using non-targeted biopsies. The primary outcome is the neoplasia detection rate. The required sample size to demonstrate non-inferiority is 1952 persons.
Mesalamine for Colorectal Cancer Prevention Program in Lynch Syndrome
Lynch SyndromeColon Cancer1 moreMulticenter, multinational, randomized, 2-arm, double-blind, phase II clinical study with 2000mg mesalamine, or placebo for prevention of colorectal neoplasia in Lynch Syndrome patients during and following daily intake for 2 years.
R vs L Lateral Decubitus Positioning in Colonoscopy
Colonic AdenomaColonic CancerColonoscopy continues to be the gold standard in detecting precancerous lesions in the colon. It relies on adequate visualization of the bowel wall to see and remove such lesions. Visualization is improved with luminal distention, and a multitude of studies have been done to determine ways to increase this luminal distention. The investigators theorize that positioning in the Right Lateral Decubitus rather than the Left Lateral Decubitus may be a cost free method to increase luminal distention and, hence, improve visualization in colonoscopy. In the Right Lateral Decubitus position, the sigmoid colon and cecum - both parts of the bowel that are not fixed - air used during colonoscopy will rise in a dependent fashion, increasing luminal distention. In the left lateral decubitus position, the bowel collapses, creating an often difficult area to maneuver and visualize. The investigators would like to compare both positions to determine if it affects outcomes in colonoscopy. In particular, cecal intubation rates and adenoma detection rates.
