A RETROspective Data Collection of comPRESSion Anastomosis Using the ColonRing

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The proposed study is a post marketing, observational, retrospective data collection intended to gather and record data on patients treated with the ColonRing device in routine clinical practice at 4-6 centers. The data will assist in future evaluating the performance of the ColonRing device in regards to the creation of a colorectal anastomosis in Low Anterior Resection procedures.

Hypothesis: The performance of the ColonRing, determined by the rate of complications, will be within the acceptable range reported in the literature for alternative treatment modalities.

Further study details as provided by novoGI:

Primary Outcome Measures:
  • The rate of anastomotic leakage. [ Time Frame: 6 weeks after the procedure ]
    Anastomotic leakage is defined as evidence of a defect in the intestinal wall integrity at the anastomotic site leading to a communication between the intra and extra luminal compartments.

Secondary Outcome Measures:
  • Rate of other device related complications and measures during hospitalization and post procedure. [ Time Frame: 6 weeks after the procedure. ]

    The Following complications will be examined:

    Bleeding. Stricture (either clinical evidence of a stricture or the inability to pass a 12 mm sigmoidoscope through the anastomosis in a procedure that does not include a diversion). Septic complication (including wound infection, pelvic infection, peritonitis, abscess) Readmission, re-operation, death within two months of the procedure Extra colonic complications (including urinary infection, urinary retention, DVT, pneumonitis, pulmonary embolism, cardiac, injury to other organs - e.g. spleen, ureter)

    The following post operative measures will be reported:

    Hospitalization duration (two dates will be recorded: ready for discharge and discharge). The latter noting where the patient was discharged to - e.g. nursing home or home. First day to first postoperative flatus. First day to first postoperative bowel movements. First day of first postoperative toleration of liquids and solids (time to "keeping them down")

Estimated Enrollment: 200
Study Start Date: October 2012
Estimated Study Completion Date: July 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
The ColonRing device is intended to be used for the creation of intestinal anastomoses in colorectal surgery in both open and laparoscopic surgeries. This indication is within the currently cleared indication of the ColonRing device, which has been cleared by the US FDA and carries the CE Mark for use throughout the alimentary trct for the creation of circular end-to-end, side-to-end or side-to-side anastomosis.
