Brief Summary:
The aim of our study is to analyze the advantages of the prophylactic use of hemoclips before polypectomy in our usual clinical practice, through a prospective randomized study that determines their effectiveness compared to conventional polypectomy, assessing the decrease in immediate and delayed post-polypectomy bleeding

Condition or disease Intervention/treatment Phase
Postpolypectomy Bleeding Device: Hemoclip Device: Conventional Polipectomy Not Applicable

Detailed Description:

The methods for preventing post-polypectomy bleeding (PPB) are not standardised and there are groups that use hemoclips for this purpose.

The aim of our study is to analyze whether the use of hemoclips reduces PPB complications. It is a prospective, randomised study of patients with pedunculated polyps larger than 10mm. The patients were included in two groups (hemoclip before polypectomy -HC- and standard polypectomy -SP-)

Primary Purpose: Prevention
Official Title: Is the Use of Prophylactic Hemoclips in the Endoscopic Resection of Large Pedunculated Polyps Useful? A Prospective and Randomized Study
Study Start Date : July 2007
Actual Primary Completion Date : August 2010
Actual Study Completion Date : August 2010

Arm Intervention/treatment
Active Comparator: Hemoclip
In group HEMOCLIP, one or more clips were placed (based on the criteria of the endoscopist in accordance with the size of the pedicle), and the polyp was subsequently resected using a diathermy loop
Device: Hemoclip
A rotatable clip-fixing device "Quickclip 2" standard was used (Olympus Medical Systems Corp. Hachioji-shi, Tokyo, Japan), with an opening diameter of 135º and a maximum insertion portion diameter of 2.6 mm

Active Comparator: Conventional Polipectomy
In group CONVENTIONAL POLYPECTOMY, a conventional polypectomy was performed, which was not aided beforehand by any other hemostatic technique
Device: Conventional Polipectomy
Disposable electrosurgical snares (Olympus Medical Systems Corp. Hachioji-shi, Tokyo, Japan) and an electrosurgery unit ERBE (ERBE Elektromedizin GmbH, Germany) were used for polyp resection

Primary Outcome Measures :
  1. The Number of Polyps With Complications After Polypectomy (The Total Complication Rate) [ Time Frame: Between four and six weeks after the polypectomy, the patients were contacted by phone in order to confirm the absence of delayed bleeding ]
    In order to test the ability of prophylactic hemoclipping to prevent post-polypectomy bleeding, the investigators were required to register all the adverse events that occurred. These adverse events were called "complications", despite their severity and clinical significance

Secondary Outcome Measures :
  1. Difficult to Place the Clip [ Time Frame: During endoscopic procedure was performed (between 2007 and 2010: period over which the study was conducted) ]
    The hemoclips which were incorrectly placed, mainly because the pedicles were very thick and/or short.
