About this study
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)

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Endoscopic mucosal resectionProcedure or surgery
Nonpedunculated neoplastic colorectal polyps from 10 mm to 25 mm in diameter were resected after submucosal injection of saline solution before removal.
Conventional polypectomyProcedure or surgery
Nonpedunculated neoplastic colorectal polyps from 10 mm to 25 mm in diameter were resected using conventional polypectomy. Submucosal injection of saline solution before removal was not performed.
| Study group | Role | What they receive |
|---|---|---|
| Conventional polypectomy | Active comparator | Colorectal polyps from 10 mm to 25 mm was found. Submucosal injection of saline solution before removal was not performed for polypectomy. The snare used for polypectomy was a dual loop wire snare with a loop size of 33/16 mm (SN-3316LX, Medico's Hirata Inc., Osaka, Japan). An ERBE ICC200 (Amco, Tokyo, Japan) was used in the Endocut mode with the effect 3 current set at output limit 120W and forced coagulation current set at output limit 35W for conventional polypectomy. Prophylactic clipping after polyp removal was routinely performed. Receives: Procedure: Conventional polypectomy |
| Endoscopic mucosal resection | Experimental | Colorectal polyp from 10 mm to 25 mm was found. Submucosal injection of saline solution before removal was performed for EMR.

An ERBE ICC200 (Amco, Tokyo, Japan) was used in the Endocut mode with the effect 3 current set at output limit 120W and forced coagulation current set at output limit 35W for EMR.

Questions about this trial
What is this clinical trial studying?
A study testing Endoscopic mucosal resection and Conventional polypectomy in people with Colorectal Polyps, run by Showa Inan General Hospital at 1 site in Japan.

Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The incomplete resection rate of neoplastic polyps as determined by the histopathologic examination. (time frame: Two weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2014.
