The goal of this study is to test the effects of Seprafilm adhesion barrier on patients who are undergoing open abdomen damage control management for traumatic injuries when compared to no adhesion barrier use. Specifically, the researchers wish to study the effects of Seprafilm adhesion barrier on:

  • the number and intensity of adhesions,
  • whether there is any difference between treatment groups (Seprafilm vs. no Seprafilm) who go on to successful definitive abdominal closure,
  • rate of occurrence of secondary complications (such as abscesses) associated with short- and long-term beneficial effects of reducing adhesion formation,and
  • whether there is any difference between treatment groups regarding patient functional recovery.

Further study details as provided by Ohio State University:

Primary Outcome Measures:
  • Wound healing characteristics [ Time Frame: Participants will be followed until their open abdomen is closed. Depending on the nature and severity of the wound, this period may last as long as 1 year after the patient has been discharged. ]
    There will not be a fixed duration of outpatient follow-up (fixed follow-up in trauma patients is not practical due to the unpredictable nature of trauma population), an average (mean) follow-up will be determined for the entire cohort of patients for the purposes of the study, up to a maximum of 1 year (if available) following hospital discharge.

Secondary Outcome Measures:
  • Adhesion characteristics [ Time Frame: Up to 1 year ]
    Patients undergoing surgery in either arm of the study will be assessed for severity of intra-abdominal adhesions during each return trip to the operating room. Any patients taken back to the operating room for up to 1 year will be assessed for adhesion severity.

Other Outcome Measures:
  • Patient mortality [ Time Frame: 28 days & end of follow-up ]
    Assessment of patient mortality at 28 days, with subsequent determination of survival (i.e., patient status at last known follow-up)

  • Enterocutaneous and other fistula [ Time Frame: Up to 1 year post-injury ]
    Determination of enterocutaneous/other fistula among study patients during the hospitalization and the follow-up interval

  • Ventral hernia [ Time Frame: Up to 1 year follow-up ]
    Determination of ventral hernia presence during follow-up visits

  • Infection / Abscess / Sepsis [ Time Frame: Up to 1 year ]
    Assessment of any infection, abscess, or sepsis during the initial and the follow-up periods

  • Bowel obstruction [ Time Frame: Up to 1 year follow-up ]
    Determination of bowel obstruction during the entire available study follow-up period

  • Patient functional outcomes [ Time Frame: Up to 1 year follow-up ]
    Assessment of Glasgow Outcome Scale and the Functional Outcome Measures during the available follow-up period.

  • Would complication [ Time Frame: Up to 1 year follow-up period ]
    Tracking of wound infection, dehiscence, hernia, or any other would-related complication of complaint

Enrollment: 30
Study Start Date: April 2010
Study Completion Date: December 2013
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
The treatment group will receive Seprafilm while the control group will not receive Seprafilm. Allocation of patients will be in 1:1 ratio.
Biological: Seprafilm

Two sheets of the Seprafilm material will be applied at each reoperation. Each sheet will be cut into 1x1 inch squares and applied to the following anatomic areas:

  • Two Seprafilm pieces between the liver and the anterior abdominal wall
  • Four pieces over the exposed bowel surfaces anteriorly
  • Two slightly staggered pieces of Seprafilm in each colic gutter
  • Two pieces in the pelvic area.
  • If any of the above areas involve an anastomosis or bowel repair, then the Seprafilm should be placed at least 1 inch away from the anastomosis and/or bowel repair.
No Intervention: No Seprafilm
