Preoperative risk reduction. Strategies to optimize outcomes.

The success of hernia repair is measured by absence of recurrence, appearance of the surgical scar, and perioperative morbidity. Perioperative surgical site occurrence (SSO), defined as infection, seroma, wound ischemia, and dehiscence, increases the risk of recurrent hernia by at least 3-fold. The surgeon should optimize all measures that promote healing, reduce infection, and enhance early postoperative recovery. In the population with ventral hernia, the most common complication in the immediate perioperative period is surgical site infection. This article reviews several preoperative measures that have been reported to decrease SSOs and shorten length of hospital stay.
