Brief Summary:

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 a single center. The data will assist in further evaluating the performance of the ColonRing™ device in regards to the creation of a colorectal anastomosis.

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.

Group/Cohort Intervention/treatment
Adult Patients who underwent a laparoscopic or open colorectal resection with the creation of an anastomosis using the ColonRing™ in routine clinical practice
Device: ColonRing™
Creation of a circular Compression Anastomosis
Other Name: Compression Anaqstomosis Ring™(CAR™)27

Primary Outcome Measures :
  1. Rate of anastomotic leakage [ Time Frame: 2-mo post-op ]
    The primary study outcome is the rate of anastomotic leakage. 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 :
  1. Rate of other device related complications and measures during hospitalization and post procedure: [ Time Frame: 2-mo post-op ]

    The following complications will be examined for relation to the device:

    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)
