Brief Summary:

This clinical study is a prospective, randomized, controlled trial of patients undergoing elective colorectal surgical procedures that receive an abdominal skin incision of at least 6 cm. Treatment with Silverlon® will be compared to standard postoperative dressings of 4x4 Gauze and paper tape. Patients will be randomized with a 1:1 treatment allocation ratio to receive either 1) Silverlon® or 2) standard postsurgical dressing. Neither the Investigators nor the participants will be blinded to the treatment modality after randomization.

Silver has long been known to have antimicrobial properties. It interacts with structural proteins and DNA, inhibiting bacterial replication and causing fatal structural changes within the cell wall. It has broad antimicrobial activities and unlike antibiotics, it is rarely associated with microbial resistance. Silverlon® is a silver-nylon dressing specifically designed for surgical wounds to prevent the development of surgical site infections. It is an easy to use product with no known microbial resistance or adverse effects. The efficacy of Silverlon® in preventing surgical site infections has been shown in several retrospective studies but as of yet has not been tested in a prospective fashion. The objective of this study is to perform a prospective, randomized, clinical trial directly comparing the incidence of surgical site infections in patients treated with Silverlon® to standard postoperative dressing following elective colorectal surgery

Actual Enrollment : 110 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A Randomized Controlled Clinical Trial Evaluating the Efficacy of Silverlon® in Preventing Surgical Site Infection Following Colorectal Surgery
Study Start Date : June 2009
Actual Primary Completion Date : September 2010
Actual Study Completion Date : November 2010

Arm Intervention/treatment
Experimental: Silverlon Dressing
The Silverlon(Cura Surgical, Geneva, IL) dressing is applied to the surgical wound postoperatively. This dressing is coated with silver nylon.
Other: Silverlon
Silverlon dressings are gauze impregnated with silver ions

Active Comparator: Standard of Care Dressing
The standard plain gauze is used to dress the wound postoperatively
Other: Standard of Care Dressing
Standard dry gauze dressing

Primary Outcome Measures :
  1. Surgical Site Infection [ Time Frame: Day of surgery up to 30 days post operatively ]
    We will monitor the incision from the day of surgery to post operative day 30 to determine if the incision needs antibiotics.
