Pediatric laparoscopic-assisted gastric transposition: early experience and outcomes

astric transposition in children is a well-established treatment for long-gap esophageal atresia and long caustic strictures when preservation of the native esophagus is impossible, but does involve laparotomy and, often, thoracotomy incisions. The minimally invasive approach to this operation has been attempted in 7 patients to date in the UK, all at Great Ormond Street Hospital (London, UK). Four patients were male, 3 were female, with a mean age of 3 years and 7 months (range, 5 months to 13 years). Indications were long-gap esophageal atresia where primary anastomosis was impossible (5 patients) and caustic ingestion with long esophageal strictures (2 patients). The stomach was mobilized laparoscopically by using 5-mm instruments and a pneumoperitoneum of 10 mm Hg. Following pyloromyotomy or pyloroplasty, a tunnel in the posterior mediastinum was developed. The fundus of the stomach was drawn to the neck and sutured to the cervical esophagus. The patients were ventilated on our intensive care unit and then returned to the surgical ward before discharge. Gastric transposition was completed laparoscopically in 6 of 7 patients. The mean duration of surgery was 327 minutes (range, 240-455). All patients survived. Minor complications were pneumonia (2), pleural effusion (1), and hiatus hernia (2). The mean hospital stay was 16 days (range, 8-36). Our preliminary experience would suggest that laparoscopic gastric transposition is a safe alternative to open surgery with satisfactory results.
