RESUMO
INTRODUCTION: We sought to better characterize outcomes in pediatric patients requiring open abdomen for instability with ongoing resuscitation, second look surgery, or left in discontinuity or congenital or acquired loss of domain that may lead to prolonged open abdomen (POA) or difficulties in successful abdominal wall closure. METHODS: We performed a single-institution retrospective review of patients aged less or equal to 18 years who presented to our institution from 2015 to 2022. We defined POA as requiring three or more surgeries prior to abdominal wall closure. Descriptive statistics were performed using median and interquartile range. RESULTS: Median age was 15 years (interquartile range 0-6 years), 46% female, and 69% White. Survival rate was 93% for the entire cohort. The most common indication for open abdomen was second look/discontinuity 22/41 (54%). The most common temporary abdominal wall closure was wound vac (43%). Fifty eight percent patients achieved primary tissue closure, the remaining required mesh. Of the 42 patients, 25 required POA. They had increasing rate of secondary infections at 56% compared to 44% (P = 0.17). The groups were further divided into indications for open abdomen including ongoing resuscitation, second look/discontinuity, and loss of domain with similar outcomes. CONCLUSIONS: In the largest series of long-term outcomes in pediatric patients with an open abdomen, we found that a majority of children were able to be primarily closed without mesh despite the number of surgeries required. Further studies require a protocolized approach to improve the long-term outcomes of these patients.
