Complete Removal of Neoplastic Large Colorectal Polyps: a Prospective Randomized Comparison of Endoscopic Mucosal Resection or Conventional Polypectomy

Recently, it was reported that the incomplete resection rate of neoplastic large polyps after conventional polypectomy was markedly high in clinical practice. The incomplete resection rate of neoplastic large polyps after endoscopic mucosal resection (EMR) is not known.

The aim of this study is to compare the incomplete resection rate of neoplastic large polyps after EMR or conventional polypectomy. The EMR technique is preferable to conventional polypectomy for the complete resection of the large polyps (>15 mm in diameter)

Inclusion Criteria:

• Inclusion criteria were nonpedunculated neoplastic colorectal polyps from 10 mm to 25 mm in diameter.

Exclusion Criteria:

• less than 20 years old, history of previous colorectal surgical resection, American Society of Anesthesiologists class III and IV, allergic to propofol used or its components (soybeans or eggs), or poor bowel preparation.
