NCT ID: NCT04468737 Completed - Bowel Preparation Clinical Trials

Effect of Inadequate Bowel Preparation on Urgent Colonoscopy in Patients With PPB.

PPB
Start date: January 1, 2010
Phase:
Study type: Observational

The purpose of this study was to explore the effect of abbreviated bowel preparation on repeated colonoscopy in patients with PPB.

NCT ID: NCT04328987 Completed - Clinical trials for Post Polypectomy Bleeding

Safety of Cold Snare Polypectomy in Patients With Uninterrupted Antiplatelet Agent

Start date: April 10, 2020
Phase:
Study type: Observational

Polypectomy is regarded as high risk for bleeding. Several guidelines recommend continuous use of aspirin during polypectomy. However for clopidogrel, widely used antiplatelet agent, cessation of 5-7 is recommended. There is insufficient data regarding clopidogrel on post polypectomy bleeding. Delayed bleeding after polypectomy in patients with clopidogrel was reported as 3%. A recent study showed that delayed bleeding rate in patients with clopidogrel didn't differ that of who stopped clopidogrel. However the rate for delayed bleeding was 4%, higher than the previous studies. More studies are needed to conclude the safety of polypectomy in clopidogrel users. Cold snare polypectomy (CSP) can resect polyps without electrical energy. CSP are safe than conventional endoscopic mucosal resection in high risk for bleeding. The polypectomy techniques in most of studies were heterogenous, where delayed bleeding was investigated in clopidogrel users. There is no study to investigate safety of CSP in patients with clopidogrel users to date. The investigators hypothesized that the bleeding risk of CSP in patients with clopidogrel users would be similar to that of aspirin users. In this multicenter prospective study, the investigators aimed to compare the safety of CSP between aspirin and clopidogrel users.

NCT ID: NCT01647581 Completed - Polypectomy Clinical Trials

Risk of Post-polypectomy Bleeding With Prophylactic Hemoclipping

Start date: September 1, 2011
Phase: N/A
Study type: Interventional

A randomized trial aimed at determining whether or not hemoclips are effective in preventing post-polypectomy bleeds on polyps that are 10mm in size or greater.

NCT ID: NCT01647568 Completed - Colonoscopy Clinical Trials

Safety of Continuing Anti-platelet Agents During Colonoscopic Polypectomy: A Prospective Study

Start date: December 2009
Phase: N/A
Study type: Observational

At our VA hospital, in general, it is the policy of our GI lab to not stop our patients anti-platelet therapy whenever they see us for a routine colonoscopy. We do this because we believe the risk of stopping these sort of medications outweigh the risks of a complication from a colonoscopy. Therefore, we are enrolling patients who are either on clopidogrel or prasugrel or not on any anti-platelet/anti-coagulant therapy that come to our GI lab routine colonoscopies. We perform the procedure just like we normally would and then follow-up with the patient 7 and 30 days after their procedure.
