Mashhad University of Medical Sciences
The objective of the study is to investigate whether peri-operative symbiotic treatment could reduce the risk of postoperative infections in patients undergoing elective colorectal surgery. This study was also designed to assess the risk-adjusted incidence and predictors of surgical site infections.

Condition Intervention Phase
Postoperative Wound Infection Biological: Symbiotic Early Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Prevention

Further study details as provided by Mashhad University of Medical Sciences:

Primary Outcome Measures:
  • Frequency of post-operative infection after elective colorectal surgery among patients with and without pre-operative symbiotic conditioning. [ Time Frame: 15 months ]

Secondary Outcome Measures:
  • The incidence of postoperative infection including surgical site infections (SSIs) and distant-site infections after elective colorectal surgery in patients whether or not receiving pre-operative symbiotic conditioning. [ Time Frame: 15 months ]

Estimated Enrollment: 150
Study Start Date: September 2011
Estimated Study Completion Date: February 2013
Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Symbiotic
Symbiotic is a combination of prebiotics and probiotics that is designed to have synergistic or additive effects benefiting the host
Biological: Symbiotic
Oral symbiotic every 8 h since 2 days before operation; Symbiotic resumes postoperatively on day +2 until day +4 for a total of 4 d of treatment (12 doses).
