Background: The purpose of this study is to examine the outcome of transumbilical minilaparotomy for infants and compare the results between normal birthweight (NBW) and low birthweight (LBW). Methods: Between July 2010 and March 2017, infants who underwent abdominal surgery through transumbilical minilaparotomy were enrolled. Medical records were retrospectively reviewed. Patients were divided into two groups, NBW and LBW. Complexity was defined as complicated conditions other than intestinal atresia and malrotation. Results: Totally, 16 patients were included. The diagnosis included intestinal atresia (n = 3), meconium peritonitis (n = 4), bowel infarction/necrosis (n = 4), spontaneous intestinal perforation (n = 2), segmental volvulus and necrosis (n = 1), necrotizing enterocolitis (n = 1), and malrotation (n = 1). The median gestational age and body weight were 32 (24–40) weeks and 1731 (560–4200) grams respectively. The median age at operation was 3 (1–41) days. The surgical procedure included primary repair of the intestine (n = 14), ileostomy (n = 1) and Ladd's procedure (n = 1). Postoperative complications included anastomotic leakage (n = 2), adhesion ileus (n = 1), and missed rectal atresia (n = 1). There was one mortality due to extremely low birthweight and poor lung maturation. Re-operation was required in 3 patients for anastomotic leakage (n = 2) and missed rectal atresia (n = 1). Mean birthweight was 2932 ± 97 and 1263 ± 667 g in NBW (n = 5) and LBW (n = 11), respectively (p < 0.01). Complexity rate was 40% and 90.9%, respectively (p = 0.034). The mean operation time was 139.4 ± 65.8 and 124.3 ± 46.1 min, respectively (p = 0.60). The complicated rate and reoperation rate were similar. Conclusions: Transumbilical minilaparotomy is technically feasible and an alternative option of minimally invasive surgery for LBW infants and complex conditions.
