Purpose:
To establish whether the rates of surgical site infection (SSI) in gastrointestinal surgery are affected by the type of intra-abdominal suturing: sutureless, absorbable material (polyglactin: Vicryl), and silk.
Methods:
We conducted SSI surveillance prospectively at 25 hospitals.
Results:
The overall SSI rate was 14.4% (130/903). The SSI rates in the sutureless, Vicryl, and silk groups were 4.8, 14.8, and 16.4%, respectively, without significant differences among the groups. In colorectal surgery, the SSI rate in the Vicryl group was 13.9%, which was significantly lower than that of the silk group (22.4%; P = 0.034). The incidence of deeper SSIs in the Vicryl group, including deep incisional and organ/space SSIs, was significantly lower than that in the silk group (P = 0.04). The SSI rates did not differ among the suture types overall, in gastric surgery, or in appendectomy.
Conclusion:
Using intra-abdominal absorbable sutures instead of silk sutures may reduce the risk of SSI, but only in colorectal surgery.
Insights
Surgical site infection (SSI) rates in gastrointestinal surgery were similar across sutureless, polyglactin (Vicryl), and silk sutures overall. However, Vicryl sutures showed reduced SSI risk compared to silk specifically in colorectal surgery.
Area of Science:
- Surgical Infections
- Gastrointestinal Surgery
- Wound Closure Materials
Background:
- Surgical site infections (SSIs) are a significant complication in gastrointestinal surgery.
- The choice of intra-abdominal suture material may influence SSI rates.
- Comparing sutureless, polyglactin (Vicryl), and silk sutures is crucial for optimizing surgical outcomes.
Purpose of the Study:
- To investigate the impact of different intra-abdominal suturing techniques on SSI rates.
- To compare sutureless, polyglactin (Vicryl), and silk sutures in gastrointestinal surgery.
- To determine if specific suture types are associated with lower SSI incidence in different surgical procedures.
Main Methods:
- Prospective surveillance of SSIs across 25 hospitals.
- Categorization of patients based on intra-abdominal suturing method: sutureless, polyglactin (Vicryl), or silk.
- Analysis of overall and procedure-specific SSI rates.
Main Results:
- The overall SSI rate was 14.4% (130/903).
- No significant differences in SSI rates were observed between sutureless, Vicryl, and silk groups overall (4.8%, 14.8%, 16.4% respectively).
- In colorectal surgery, Vicryl sutures demonstrated a significantly lower SSI rate (13.9%) compared to silk (22.4%; P = 0.034), including a reduction in deeper SSIs (P = 0.04).
Conclusions:
- Absorbable polyglactin (Vicryl) sutures may reduce the risk of surgical site infections compared to silk sutures, but this benefit appears limited to colorectal surgery.
- Suture type did not significantly impact SSI rates in gastric surgery or appendectomy.
- Further research may be warranted to explore the specific mechanisms behind reduced SSI in colorectal procedures with absorbable sutures.
