Abstract
Background and study aims Endoscopic mucosal resection is the gold standard treatment for non-pedunculated
colorectal polyps; however, some specific situations (location behind folds, scarred
or flat morphology) can make this technique challenging. We aimed to assess the efficacy
and safety of multiband mucosectomy (MBM) for resection of non-pedunculated colorectal
polyps.
Patients and methods This was a retrospective study of patients in whom MBM was performed to resect large
non-pedunculated colorectal polyps. All procedures were carried out using the Shooter
multiband ligator kit (Cook Medical, Limerick, Ireland). A 3-month follow-up colonoscopy
was performed in all patients.
Results 10 patients underwent MBM for resection of 10 large (median 33.5 mm) non-pedunculated
polyps. A total of 45 MBM sessions were carried out to resect all of the lesions using
on average one rubber band per 1.5 cm2 of resected tissue. Complete resection was possible in 9 out of 10 lesions, although
en bloc resection was only feasible in one lesion. Follow-up colonoscopy revealed
residual adenoma in just one patient. No major complications were registered.
Conclusions In this small series of patients, MBM proved to be a safe and effective endoscopic
resection technique for challenging non-pedunculated colorectal polyps.
