Introduction: The use of staples to perform intestinal anastomosis in children has gained popularity in the past years. The aim of this study is to evaluate the outcomes of pediatric patients who underwent intestinal anastomosis with a 5-mm staple in a tertiary health care center. Material and Methods: From April 2017 to November 2019, the records of all pediatric patients who underwent intestinal anastomosis with a 5-mm staple were retrospectively revised. The reconstruction technique was functional end-to-end anastomosis. Results: A total of 12 intestinal anastomoses were evaluated. Mean age at surgery was 120 days. Small bowel anastomosis was the most frequently performed procedure (eight cases). Stapling difficulties were found in 3 patients. The anastomosis could not be performed with the 5-mm endostapler in one of these patients. The median follow-up was 26 months (interquartile range 20-40 months). Postoperative complications included one bowel obstruction that was surgically treated. Conclusions: Mechanical suturing with 5-mm staple is a safe alternative technique to perform intestinal anastomosis in neonates and infants. The use of this staple has proven to be safe and feasible in pediatric patients. It is necessary to select patients carefully according to their bowel characteristics.
