Introduction of Small Stitch Small Bite technique: a retrospective long-term follow-up

Abstract

PurposeStandardization of abdominal wall closure is suggested to improve quality and reduce the risk for late abdominal wall complications. The purpose of this study was to explore the impact of a structured introduction of guidelines for abdominal wall closure on the rates of incisional hernia and wound dehiscence.MethodsAll procedures performed via a midline incision in 2010–2011 and 2016–2017 at Capio St Göran’s Hospital were identified and assessed for complications and risk factors.ResultsSix hundred two procedures were registered in 2010–2011, and 518 in 2016–2017. Four years after the implementation of new guidelines, 93% of procedures were performed using the standardized technique. There was no significant difference in the incidence of incisional hernia or wound dehiscence between the groups. In multivariate Cox proportional hazard analysis, BMI > 25, wound dehiscence, and postoperative wound infection were found to be independent risk factors for incisional hernia (all p < 0.05). In multivariate logistic regression analysis, male gender and chronic obstructive pulmonary disease were risk factors for wound dehiscence (both p < 0.05).ConclusionsThe present study failed to show a significant improvement in rates of incisional hernia and wound dehiscence after the introduction of Small Stitch Small Bites. When introducing a new standardized technique for closing the abdomen, education and structural implementation of guidelines may have an impact in the long run. The risk factors identified should be taken into consideration when closing a midline incision to identify patients with high risk.
