Abstract
BACKGROUND

Prophylactic loop ileostomy is an effective way to reduce the clinical severity of anastomotic leakage following radical resection of rectal cancer. Incisional surgical site infection (SSI) is a common complication after ileostomy closure.

AIM

To evaluate the efficacy and safety of the micro-power negative pressure wound technique (MPNPWT) in preventing incisional SSI.

METHODS

This was a prospective, randomized controlled clinical trial conducted at a single center. A total of 101 consecutive patients who underwent ileostomy closure after rectal cancer surgery with a prophylactic ileostomy were enrolled from January 2019 to December 2021. Patients were randomly allocated into an MPNPWT group and a control group. The MPNPWT group underwent intermittent suturing of the surgical incision with 2-0 Prolene and was covered with a micro-power negative pressure dressing. The surgical outcomes were compared between the MPNPWT (n = 50) and control (n = 51) groups. Risk factors for incisional SSI were identified using logistic regression.

RESULTS

There were no differences in baseline characteristics between the MPNPWT (n = 50) and control groups (n = 51). The incisional SSI rate was significantly higher in the control group than in the MPNPWT group (15.7% vs 2.0%, P = 0.031). However, MPNPWT did not affect other surgical outcomes, including intra-abdominal complications, operative time, and blood loss. Postoperative hospital stay length and hospitalization costs did not differ significantly between the two groups (P = 0.069 and 0.843, respectively). None of the patients experienced adverse effects of MPNPWT, including skin allergy, dermatitis, and pain. MPNPWT also helped heal the infected incision. Our study indicated that MPNPWT was an independent protective factor [odds ratio (OR) = 0.005, P = 0.025)] and diabetes was a risk factor (OR = 26.575, P= 0.029) for incisional SSI.

CONCLUSION

MPNPWT is an effective and safe way to prevent incisional SSI after loop ileostomy closure.

Keywords: Micro-power negative pressure technique, Ileostomy closure, Incisional surgical site infection, Infection prevention, Postoperative incision

Core Tip: This is the first study to apply the micro-power negative pressure wound technique (MPNPWT) to postoperative incision for incisional surgical site infection (SSI) prevention. The efficacy and safety of MPNPWT in preventing incisional SSI after ileostomy closure were evaluated. Our study showed that MPNPWT significantly reduced the incisional SSI rate to a low level (2.0%). No patients suffered adverse effects with MPNPWT. MPNPWT is an effective and safe way to prevent incisional SSI after loop ileostomy closure.
