A systematic review and meta-analysis examined patients with colorectal polyps to compare balloon-assisted endoscopic submucosal dissection against conventional endoscopic submucosal dissection. The analysis included 1,449 patients from various studies. Researchers looked at how well the polyps were removed, how long the procedures took, and safety issues like bleeding or perforation.
The study found no significant difference between the two methods for removing polyps completely or achieving clear margins. However, when looking specifically at randomized controlled trials, the balloon-assisted technique resulted in significantly shorter procedure times. There was no significant difference in dissection speed overall.
Safety outcomes showed no significant difference between the two methods for bleeding or perforation. The review noted that previous studies had conflicting results. The authors suggest that large-scale multicenter randomized controlled trials are needed to further evaluate these findings. Readers should understand that while procedure time improved in specific trial settings, the overall evidence remains limited by prior conflicting data.
