Background
Children with congenital heart disease (CHD) often require noncardiac surgery. We compared outcomes following open and laparoscopic intraabdominal surgery among children with and without CHD.Methods
We performed a retrospective cohort study using the 2013–2015 National Surgical Quality Improvement Project-Pediatrics. We matched 45,012 children < 18 years old who underwent laparoscopic surgery to 45,012 children who underwent open surgery. We determined the associations between laparoscopic (versus open) surgery and 30-day mortality, in-hospital mortality, 30-day morbidity, and postoperative length-of-stay.Results
Among children with minor CHD, laparoscopic surgery was associated with lower 30-day mortality (Odds Ratio [OR] 0.34 [95% Confidence Interval 0.15–0.79]), inhospital mortality (OR 0.42 [0.22–0.81]) and 30-day morbidity (OR 0.61 [0.50–0.73]). As CHD severity increased, this benefit of laparoscopic surgery decreased for 30-day morbidity (ptrend = 0.01) and in-hospital mortality (ptrend = 0.05), but not for 30-day mortality (ptrend = 0.27). Length-of-stay was shorter for laparoscopic approaches for children at cost of higher readmissions. On subgroup analysis, laparoscopy was associated with lower odds of postoperative blood transfusion in all children.Conclusions
Intraabdominal laparoscopic surgery compared to open surgery is associated with decreased morbidity in patients with no CHD and lower morbidity and mortality in patients with minor CHD, but not in those with more severe CHD.Level-of-evidence

Introduction
Anthropometric measurements can be used to define pediatric malnutrition. Our study aims to: (1) characterize the preoperative nutritional status of children undergoing abdominal or thoracic surgery, and (2) describe the associations between WHO-defined acute (stunting) and chronic (wasting) undernutrition (Z-scores <?2) and obesity (BMI Z-scores > + 2) with 30-day postoperative outcomes.Methods
We queried the Pediatric NSQIP Participant Use File and extracted data on patients’ age 29 days to 18 years who underwent abdominal or thoracic procedures. Normalized anthropometric measures were calculated, including weight-for-height for < 2 years, BMI for ages ≥ 2 years, and height for age. Logistic regression models were developed to assess nutritional outlier status as an independent predictor of postoperative outcome.Results
23,714 children (88% ≥ 2y) were evaluated. 4272 (18%) were obese, while 2640 (11.1%) and 904 (3.8%) were stunted and wasted, respectively, after controlling for gender, ASA/procedure/wound classification, preoperative steroid use, need for preoperative nutritional support, and obese children had higher odds of SSIs (OR 1.29, 95% CI 1.1–1.5, p = 0.001), while stunted children were at increased risk of any 30-day postoperative complication (OR 1.16, 95% CI 1.0–1.3, p = 0.036).Conclusion
Children who are stunted or obese are at increased risk of adverse outcome after abdominal or thoracic surgery.Level of Evidence
