A 6 to 10 mm colon polyp can look routine until the shape, margin, and histology make the resection less forgiving. In this clip, Klaus reviews why a small lesion still needs an individualized plan. The goal is simple: remove the lesion safely, completely, and with margins that can stand up to pathology.
Why Shape Should Drive the Resection
The key teaching point is that the polyp tells you how it wants to be resected. Cold snare can be ideal for a small sessile or slightly elevated lesion, but lateral margins may not always be included. Serrated and flatter lesions are the ones that deserve extra attention.
Klaus points to evidence showing incomplete resection in serrated histology and argues for a more deliberate approach. Sometimes that means choosing a dedicated cold snare with a stiff wire and shaft. Sometimes it means suctioning or injecting the lesion to reshape it before placing the snare.
Klaus shows the exact moment when suction or injection changes the resection plan.
Watch how he selects the snare, reshapes the lesion, and checks whether the margins are likely to be complete.
