OESOPHAGEAL LENGTHENING BY TRACTION IN OESOPHAGEAL ATRESIA: THE UK EXPERIENCE

Abstract AIMS Preliminary reports suggest a promising role for oesophageal lengthening by traction (OLBT) in long gap oesophageal atresia (LGOA). Nevertheless, these encouraging results originate from specialist centres, and real-world experience is unquantified. We report the first multicentre, nationwide study of OLBT. METHODS Cumulative experience of OLBT was recorded through a questionnaire sent to all UK paediatric surgery centres. OLBT was defined as “any attempt to increase oesophageal length using tension sutures”. Contributors submitted all cases of attempted OLBT, regardless of outcome. Demographics, surgical detail, and outcomes were analysed with summary statistics. RESULTS The response rate was 23/26 centres. Eleven centres reported using OLBT in 22 patients (2003-2020) with 117 LGOA treated by other means. One patient died from complications of cardiac surgery and was excluded. OLBT enabled oesophageal anastomosis in 16 (76%), of which 2 died of complications of surgery, and another died of unrelated disease. Of the survivors, 7 required oesophageal dilatation 2-14 times. Oesophageal anastomosis was not achieved in 5 (24%) patients. All had pouch leak or disruption pre- or peri-operatively and underwent cervical oesophagostomy with subsequent gastric pull-up. One patient required dilatation of the oesophagogastric anastomosis. CONCLUSION OLBT is being carried out in the UK in a limited number of centres in a minority of patients. These data suggest OLBT enables oesophageal anastomosis in 76% of infants with LGOA. Oesophageal pouch leak or disruption was common to all instances of failure to anastomose. Our findings will inform discussions between surgeons and families of babies born with LGOA.
