BackgroundVarious treatment modalities are utilized to treat the open abdomen. The use of negative pressure wound therapy(NPWT)has been a great advancement and has become the preferred modality for temporary abdominal closure technique (TAC). Programmed instillation of the abdominal cavity with saline solution in conjunction with a commercial negative pressure system showed positive results in the management of severe abdominal sepsis in patients that were treated with an open abdomen. Severe abdominal sepsis continues to be an oftendifficult clinical problem for the general surgeon. The use of an open abdomen technique in this setting and the ideal TAC method continue to be debated. The failure to understand the biomechanical features/limitations of negative pressure devices are often contributing factors associated with therapeutic failures reported in the literature.ObjectivesTo describe the underlying principles behind negative pressure wound therapy with instillation in the context of abdominal sepsis, as well as its optimal usage in these conditions.MethodsA systematic review and two retrospective cohort studies, both published and unpublished performed by some of the authors were included to provide a basis form comparison between NPWT and NPWT-I outcomes in managing abdominal sepsis.ConclusionOur findings suggest that this technique appears to reduce morbidity, mortality, and hospital and critical care length of stay. This communication is intended to help inform general surgeons that manage complex abdominal infections on how to optimally apply this technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
