Randomised Comparison of 2 Cold Snare Polypectomy Techniques

August 12, 2014 updated by: Sheffield Teaching Hospitals NHS Foundation Trust

A Prospective Randomised Comparison of Cold Snare Polypectomy Versus Cold Snare Pseudosuction Technique

Different modalities are employed to remove small colonic polyps which potentially harbour a cancer risk. But, they can all vary in their completeness of removal, safety and the histological quality and the gold standard technique has yet to be defined. A novel suction pseudopolyp technique has been described by Patullo et al and in their prospective study, 126 polyps measuring less than 10mm flat or sessile were removed by this method with 100% complete endoscopic resection and without any immediate or delayed complications. The aim of the investigators study is to compare this technique with the standard cold snare technique. Patients attending for a routine colonoscopy and found to have polyps measuring 37mm in size will be eligible and they will be randomised to the polypectomy technique. Patient demographics and polyp characteristics will be recorded. The primary outcome measured will be the macroscopic resection rate. The secondary outcome measures are abdominal pain, tenderness, bleeding and fever.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Complete macroscopic polyp eradication rate
Time Frame: At time of polypectomy intervention
The primary outcome for this study is the polypectomy completion rate. This will be assessed both macroscopically and histologically. The analysis for statistical difference between the 2 techniques and abdominal symptoms will be compared by the Chi2 test for categorical data.
At time of polypectomy intervention
