Purpose
We sought to compare the effectiveness of a novel antibiotic irrigation device to the standard O-ring wound retractor in preventing surgical site infections (SSIs) following colorectal resections.
Methods
This single-arm clinical trial included patients undergoing colorectal resections utilizing the novel device. A retrospective cohort of patients undergoing the same procedures with the O-ring retractor was selected as the control group. The primary outcome assessed was SSI. Secondary outcomes assessed were overall complications, hospital length of stay (LOS), and 30-day readmission. A univariable and multivariable logistic regression model was built to evaluate the association between SSI as the outcome variable and the use of the novel device as the main independent variable. The model was adjusted for any confounding variables.
Results
Eighty-six novel device cases and 170 O-ring retractor cases were enrolled. There were no significant differences between the two groups in terms of demographics and preoperative comorbidities. Cases with the novel device had fewer Pfannenstiel incisions (1.2% vs. 14.6%, p < 0.001). There were no other significant differences in intraoperative variables. SSI rates were significantly lower in the novel device group (1.2% vs. 9.1%, p = 0.014). There were no other significant differences in postoperative complications. Multivariable logistic regression with backward elimination showed that the use of the novel device was significantly more effective against SSI by 92.5% compared to the use of the O-ring retractor.
Conclusion
The novel device may contribute to lower SSI rates compared to the O-ring retractor following colorectal resection.
