Application of PREVENA (Surgical Incision Protection System) in reducing surgical site infections following reversal of ileostomy or colostomy: the PRIC study protocol

The use of negative pressure wound therapy following stoma reversal: a systematic review and meta-analysis of randomized controlled trials

INTRODUCTION

Stoma reversal is a contaminated surgery with many patients experiencing significant wound complications that contribute to patient morbidity. It is believed that the use of prophylactic negative pressure wound therapy (NPWT) may enhance wound healing and help reduce the risk of developing surgical site infections (SSI). However, there is conflicting research regarding its effectiveness following stoma reversal. Our systematic review aims to evaluate the available randomized data to determine if the use of prophylactic NPWT after stoma reversal improves the duration of wound healing and reduces rates of postoperative complications.

METHODS

A comprehensive search of literature published up to January 2025 was conducted using the following databases: PubMed, Embase, Medline, and Cochrane Library. The included trials were randomized controlled trials that investigated the effect of NPWT following stoma reversal. The primary outcome was the time to complete wound healing. Secondary outcomes included the incidence of wound complications, SSI, hematomas, and the length of hospital stay.

RESULTS

Six randomised control trials were included, with 332 patients, of which 171 of these underwent NPWT. There was a significant reduction in time to complete wound healing (OR - 2.53, 95% CI - 3.82 to - 1.24, p = 0.0001, I2 = 45%) and wound healing at 42 days (OR 0.36, 95% CI 0.14 - 0.88, p = 0.03, I2 = 0%) in the NPWT group. There was no significant difference in any wound complications (OR 0.72, 95% CI 0.23-2.28, p = 0.58, I2 = 42%), SSI rates (OR 0.95, 95% CI 0.27-3.29, p = 0.94, I2 = 38%) or haematoma rates (OR 0.21, 95% CI 0.03-1.27, p = 0.09, I2 = 0%) between the groups. There was no significant difference in length of stay (OR - 0.02, 95% CI - 1.21-1.18, p = 0.98, I2 = 66%).

CONCLUSION

The use of NPWT after stoma reversal significantly reduces the time needed for complete wound healing while maintaining a comparable rate of wound complications and length of hospital stay. Therefore, NPWT may be valuable in optimizing postoperative recovery and enhancing patient outcomes.

Effect of Negative Pressure Wound Therapy on Surgical Site Infections following Stoma Reversal in Colorectal Surgery: A Meta-Analysis

BACKGROUND

Surgical site infections (SSI) are common complications after surgery, which cause other complications and increase medical costs. However, the effect of negative-pressure wound therapy (NPWT) for the prevention of SSI at stoma reversal remains inconclusive, with controversial results. This meta-analysis aimed to evaluate the safety and efficacy of NPWT following stoma reversal in colorectal surgery to prevent SSI and other wound complications.

METHODS

We conducted a systematic search of the PubMed, EMBASE, and Cochrane Library databases for articles published up to July 2022 and identified relevant studies reporting the NPWT administration following stoma reversal in colorectal surgery compared with non-pressure dressing. The primary outcome was the incidence of SSI, and the secondary outcomes were hematoma, seroma, and length of hospital stay (LOS).

RESULTS

Nine studies were included in the meta-analysis, with 825 patients with (n = 310) or without (n = 515) NPWT. Pooled SSI rate was lower in the NPWT group than in the non-pressure dressing group (OR = 0.50; 95% CI: 0.29, 0.84; P = 0.01). There was no significant effect on hematoma (OR = 0.21; 95% CI: 0.03, 1.27; P = 0.09), seroma (OR = 0.26; 95% CI: 0.05, 1.28; P = 0.1) and LOS (MD = -0.16, 95% CI: -0.83, 0.51; P = 0.64).

CONCLUSION

The use of NPWT following stoma reversal in colorectal surgery reduced the incidence of SSI. However, this conclusion needs to be interpreted with caution, and further studies should be conducted to confirm in higher-quality RCTs.

Risk factors analysis of surgical site infections in postoperative colorectal cancer: a nine-year retrospective study

BACKGROUND

Colorectal cancer (CRC) patients undergoing surgery are at a high risk of developing surgical site infections (SSIs), which contribute to increased morbidity, prolonged hospitalization, and escalated healthcare costs. Understanding the incidence, risk factors, and impact of SSIs is crucial for effective preventive strategies and improved patient outcomes.

METHODS

This retrospective study analyzed data from 431 CRC patients who underwent surgery at Huangshan Shoukang Hospital between 2014 and 2022. The clinical characteristics and demographic information were collected. The incidence and impact of SSIs were evaluated, and independent risk factors associated with SSIs were identified using multivariable logistic regresison. A nomogram plot was constructed to predict the likelihood of SSIs occurrence.

RESULTS

The overall incidence rate of SSIs was 7.65% (33/431). Patients with SSIs had significantly longer hospital stays and higher healthcare costs. Risk factors for SSIs included elevated Body Mass Index (BMI) levels (odds ratio, 1.12; 95% CI, 1.02-1.23; P = 0.017), the presence of diabetes (odds ratio, 3.88; 95% CI, 1.42 - 9.48; P = 0.01), as well as specific surgical factors such as open surgical procedures (odds ratio, 2.39; 95% CI [1.09; 5.02]; P = 0.031), longer surgical duration (odds ratio, 1.36; 95% CI [1.01; 1.84]; P = 0.046), and the presence of a colostomy/ileostomy (odds ratio, 3.17; 95% CI [1.53; 6.62]; P = 0.002). Utilizing multivariable regression analysis, which encompassed factors such as open surgical procedures, the presence of diabetes and colostomy/ileostom, the nomogram plot functions as a visual aid in estimating the individual risk of SSIs for patients.

CONCLUSIONS

Risk factors for SSIs included higher BMI levels, the presence of diabetes, open surgical procedures, longer surgical duration, and the presence of colostomy/ileostomy. The nomogram plot serves as a valuable tool for risk assessment and clinical decision-making.
