Background
Clip-assisted endoscopic full-thickness resection (EFTR) with an over-the-scope device has been recently described to be feasible and effective for the resection of non-lifting adenomas in the lower gastrointestinal tract. However, tumor size is the major limitation of that technique. We describe a hybrid technique using endoscopic mucosal resection (EMR) in ten patients with large non-lifting colorectal adenomas to reduce tumor size and facilitate clip-assisted EFTR.
Methods
Data of ten consecutive patients (median age 72.5 years, SD 8.86) who underwent combined EMR and EFTR in the colon were analyzed retrospectively. The main outcome measures were technical success, histological confirmation of full-thickness resection, and adverse events.
Results
All lesions (median size 35.5 mm, SD 5.99) could be resected successfully. No immediate or delayed adverse events were observed. Histology confirmed full-thickness resection in all cases. Three-month follow-up showed no residual or recurrent adenomas.
Conclusions
Hybrid EMR–EFTR in the colon seems to be an effective approach for large non-lifting lesions with positive lateral lifting signs. Prospective studies are needed to further evaluate efficacy, safety, rate of recurrence, and long-term outcome of this technique.
