Objectives:
To examine whether the administration of mechanical bowel preparation (MBP) plus oral antibiotic bowel preparation (OABP) was associated with reduced surgical site infections (SSIs), which in turn leads to a reduction of non-SSI-related postoperative complications.
Background:
Administration of MBP/OABP before elective colectomy reduces the incidence of SSI. We hypothesized that reduction of SSI is on causal pathway between the use of MBP/OABP and the reduction of other postoperative complications.
Methods:
The study population consisted of all colectomy cases in the American College of Surgeons National Surgical Quality Improvement Program Colectomy Targeted Participant Use Data File for 2012 and 2013. Postoperative outcomes were compared based on the type of bowel preparation: none, MBP only, OABP only, and MBP plus OABP adjusting for other covariates.
Results:
The cohort included 19,686 patients. Of these 5060 (25.7%) patients did not receive any form of bowel preparation, 8020 (40.7%) received MBP only, 641 (3.3%) received OABP only, and 5965 (30.3%) received MBP plus OABP. Patients who received MBP plus OABP had a lower incidence of superficial SSI, deep SSI, organ space SSI, any SSI, anastomotic leak, postoperative ileus, sepsis, readmission, and reoperation compared with patients who received neither (all P < 0.01). The reduction in SSI incidence was associated with a reduction in wound dehiscence, anastomotic leak, pneumonia, prolonged requirement of mechanical ventilator, sepsis, septic shock, readmission, and reoperation.
Conclusions:
Combined MBP plus OABP before elective colectomy was associated with reduced SSI, which ultimately was associated with a reduction in non-SSI-related complications.
Insights
Combining mechanical and oral antibiotic bowel preparation before colectomy significantly reduces surgical site infections (SSIs) and subsequent non-SSI complications, improving patient outcomes.
Area of Science:
- Surgical Oncology
- Infectious Disease Prevention
- Colorectal Surgery Outcomes
Background:
- Surgical site infections (SSIs) are a significant concern following colectomy.
- Mechanical bowel preparation (MBP) and oral antibiotic bowel preparation (OABP) are used to reduce SSI incidence.
- The causal pathway between MBP/OABP, SSI reduction, and other postoperative complications requires further investigation.
Purpose of the Study:
- To determine if combined mechanical bowel preparation (MBP) plus oral antibiotic bowel preparation (OABP) reduces surgical site infections (SSIs).
- To assess if reduced SSIs, achieved through MBP plus OABP, lead to fewer non-SSI-related postoperative complications.
Main Methods:
- Analysis of colectomy cases from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2012-2013).
- Comparison of postoperative outcomes based on bowel preparation: none, MBP only, OABP only, and MBP plus OABP.
- Statistical adjustment for covariates to isolate the effect of bowel preparation strategies.
Main Results:
- The study included 19,686 patients; 30.3% received MBP plus OABP.
- MBP plus OABP was associated with significantly lower rates of superficial, deep, and organ space SSIs compared to no preparation (P < 0.01).
- Reduced SSI incidence correlated with decreased rates of anastomotic leak, sepsis, readmission, and reoperation.
Conclusions:
- Combined MBP plus OABP is an effective strategy for reducing SSIs in elective colectomy.
- The reduction in SSIs achieved by combined MBP plus OABP contributes to a decrease in various non-SSI-related postoperative complications.
- This comprehensive bowel preparation regimen improves overall patient outcomes after colectomy.
