RESUMO
PURPOSE: Single-site umbilical laparoscopic pyloromyotomy for hypertrophic pyloric stenosis in neonates <3-week old has rarely been reported in the literature. This article reports our initial experience with this procedure. METHODS: Overall, 13 cases of hypertrophic pyloric stenosis occurred in neonates <3-week old from January 2010 to April 2013 in our hospital. All neonates were treated by a single-site laparoscopic procedure. A 5-mm trocar and endoscope were introduced through an incision in the center of the umbilicus, and two 3-mm working instruments were inserted directly into the abdomen via separate lateral fascial stab incisions in the umbilical fold, and a single-site umbilical laparoscopic pyloromyotomy was then performed. RESULTS: The procedure was performed in 13 infants (12 male) with mean age of 17.3 days. The average length of the operation was 26 min. The mean postoperative hospital stay was 4.5 days. All patients were discharged home on full feeds. Follow-up examinations were scheduled 2 to 6 weeks after discharge, and no postoperative complications were noted in any of the patients. CONCLUSION: These cases had shorter and thinner pylori than their older counterparts. However, the laparoscopic procedure was safe and feasible, with good postoperative results and excellent cosmesis. Surgeons should have a firm foundation of advanced minimal access surgical skills prior to attempting the procedure.
