Single-Instrument Thoracic and Abdominal Surgery in Children: Minimizing Minimally Invasive Surgery.

Introduction: The use of single-port surgery is widely accepted in pediatric surgery, but the majority of reports are on its use for appendectomy or inguinal hernia repair using multiple instruments. The aim of this report is to demonstrate that both thoracic and abdominal single-instrument procedures are feasible and safe in children. Materials and Methods: The following cases were managed in our department for the past 12 months. Two types of telescopes (10- and 5-mm) with inbuilt working channels were used in all cases. Results: The 10-mm endoscope with a 6-mm inbuilt channel was used to partially reduce and then exteriorize an intussusception secondary to Meckel's diverticulum in a 9-year-old boy, to reduce a left ovarian torsion in a 8 year-old girl, and to perform a thoracoscopic exploration and lung decortication in a 16 year-old girl with empyema. A 5-mm endoscope with a 3-mm working channel was used to perform bilateral 2-level thoracic sympathotomy in a 13-year-old girl with palmar primary hyperhidrosis. There were no perioperative complications and follow-up was uneventful in all patients. Conclusion: Minimally invasive surgery is well established at present. Thoracic and abdominal single-port single-instrument procedures are safe and effective in children. This is a unique report on single-port single-instrument use in four completely different procedures and the first to describe its usage for thoracoscopic sympathotomy in children. Increasing technology development, allied to surgeons' skills, is crucial to worldwide adoption of this surgical modality.
