Laparascopic Assisted Colonoscopic Polypectomy

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01986699
Recruitment Status : Completed
First Posted : November 18, 2013
Last Update Posted : May 12, 2015

Stony Brook University

Brief Summary:
Study Objective: To compare the hospital costs between the standard surgical procedure and the Laparascopic Assisted Colonoscopic Polypectomy (LACP) technique for patients with advanced polyps in the colon.

Condition or disease Intervention/treatment
Colon Polyps Procedure: Laparoscopic Assisted Polypectomy

Detailed Description:
All patients being referred for possible LACP to the Division of Colorectal Surgery at Stony Brook University Medical Center will be randomized in a 1:1 fashion using a computer generated system to undergo either partial colectomy (performed by means of laparoscopy when possible), or LACP for the treatment of advanced polyp(s). Our research assistant will be present in the operating room to record the data.Patients will then undergo standard clinical management while hospitalized at Stony Brook according to the procedure performed.

Procedure: Laparoscopic Assisted Polypectomy
Laparoscopic Assisted Polypectomy
Patients treated with Laparoscopic Assisted Colonoscopic Polypectomy
Procedure: Laparoscopic Assisted Polypectomy

Primary Outcome Measures :
  1. hospital cost [ Time Frame: 1-3 days ]
    To compare the hospital costs between the standard surgical procedure and the LACP technique for patients with advanced polyps in the colon.

Secondary Outcome Measures :
  1. complication rates [ Time Frame: 1-3 days ]
    to compare complication rates between both techniques including intra-operative polypectomy related perforaton, polypectomy-related bleeding unable to be stopped endoscopically, post operative wound infection, ileus and anastomic leak.

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 90 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
GI clinic

Inclusion Criteria:

  • Polyp spanning 2 or more colonic folds
  • Polyp > 20mm
  • Polyp spanning greater than 50% of the colonic circumference
  • Positive "lift sign" following submucosal injection of saline beneath the polyp
  • Difficult location or position of the polyp, thus preventing assurance of complete endoscopic resection.

Exclusion Criteria:

  • Polyps with histological evidence of adenocarcinoma
  • Polyps in the rectum (<15cm from anal verge)
  • Patients with known inflammatory bowel disease (IBD).
  • Patients with known familiar adenomatous polyposis (FAP) syndrome
  • Polyps without known histology (i.e. not previously biopsied)
  • Polyps with large ulcerations, or those that demonstrate a "non-lift sign" during submucosal injection at the time of colonoscopy; as these are indicators of adenocarcinoma .
  • Severe cardio-pulmonary disease, or irreversible coagulopathy, preventing abdominal surgery at an acceptable risk.
  • POSSUM predicted mortality score greater than 2%
  • Inability to obtain informed consent
  • Patients under the age of 18
  • Pregnant patients
