Colonoscopic electrosurgical resection of high-risk polyps: Pretreatment methods

Value and Interpretation of Resection Margin after a Colonoscopic Polypectomy for Malignant Polyps

PURPOSE This study was designed to compare the clinicopathologic findings of an endoscopic polypectomy for malignant polyps with subsequent surgery and to evaluate the appropriateness of the pathologic finding criterion of the resection margin as an indicator for surgery in cases of malignant colorectal polyps. METHODS We examined the clinicopathologic characteristics, complications and progn...

Double-channel colonoscopic snare resection of large pedunculated polyps using a clipping method.

ed with colonoscopic polypectomy is bleeding, the rate ranging from 0.44 % to 2.6 % [1, 2]. Iida et al. [3] used a clipping method for endoscopic polypectomy in 40 patients. However, this maneuver might be quite difficult to accomplish with a single−channel endoscope when the endoscopic view of the pedicle is lim− ited. We developed a new and easy clip− ping technique for double−channel colon− ...

Endoscopic Instruments and Electrosurgical Unit for Colonoscopic Polypectomy

Colorectal polypectomy is an effective method for prevention of colorectal cancer. Many endoscopic instruments have been used for colorectal polypectomy, such as snares, forceps, endoscopic clips, a Coagrasper, retrieval net, injector, and electrosurgery generator unit (ESU). Understanding the characteristics of endoscopic instruments and their proper use according to morphology and size of the...

Risk Factors for Incomplete Polyp Resection during Colonoscopic Polypectomy

BACKGROUND/AIMS Colonoscopic polypectomy is highly efficient in preventing colorectal cancer, but polyps may not always be completely removed. Improved knowledge of the risk factors for incomplete polyp resection after polypectomy may decrease the cancer risk and additional costs. The aim of this study was to investigate the conditions that can cause incomplete polyp resection (IPR) after colon...
