ARTICLE HIGHLIGHTS
Research background

Although ileostomy closure is technically easy, it is associated with a non-negligible overall morbidity rate (11%-37%), with incisional surgical site infection (SSI) being the most common.

Research motivation

The incisional SSI rate after ileostomy closure is much higher than those of other intestinal surgeries, ranging from 2% to 40%. Incisional SSI is responsible for increased pain, longer hospital stays, and higher treatment costs. Current methods for incisional SSI prevention have limitations. Finding a new approach to prevent incisional SSI is urgent for patients receiving ileostomy closure.

Research objectives

Micro-power negative pressure wound technique (MPNPWT) contains a special material that produces micro-negative pressure by absorbing exudates rather than suction device. It reduces wound edema and stimulates epithelial cell proliferation and granulation tissue growth, thus shortening wound healing time. This study aimed to evaluate the efficacy and safety of MPNPWT in preventing incisional SSI. The results of our study will provide foundation for future application of MPNPWT.

Research methods

This was a single-center, prospective, randomized controlled trial (RCT). An independent statistician randomly assigned eligible patients in a 1:1 ratio using sequentially sealed envelopes to a control group or an MPNPWT group without stratification. Micro-power negative pressure dressing was filled on the skin surface of patients in the MPNPWT group by nurses from wound care clinic.

Research results

MPNPWT significantly reduced incisional SSI rate (2.0%). MPNPWT is a safe technique without any side effect. MPNPWT could also help heal the infected incision.

Research conclusions

Our study introduces a novel technique, MPNPWT, to prevent incisional SSI after loop ileostomy closure. MPNPWT reduces the incidence of incisional SSI after loop ileostomy closure.

Research perspectives

A larger RCT with a larger sample is the direction of the future research.
