Abstract: | AimsOesophageal atresia (OA) with or without tracheoesophageal fistula (TOF) is the most common congenital anomaly of the oesophagus. There is limited literature suggesting a linear relationship between increasing gap length and the incidence of all major complications. We sought to assess whether measured gap length at the time of surgery was related to outcomes in our patients.MethodsAll patients with a diagnosis of OA +/− TOF who underwent repair under a single surgeon between 1983 and 2012 were included. The length between the oesophageal pouches was measured at the time of surgery. Patients were then divided into three groups; short ≤ 1 cm, intermediate > 1–≤2 cm and long > 2–≤5 cm. Outcome measures were anastomotic leak, strictures requiring dilatation, gastrooesophageal reflux disease (GORD) and need for fundoplication.Results122 patients were included in the study. The outcomes for patients with short (n = 53), intermediate (n = 51) and long gaps (n = 18) were as follows: anastomotic leak — 1.9%, 2%, 5.5% (P = 0.66), strictures requiring dilatation — 32%, 33%, 50% (P = 0.67), GORD — 51%, 59%, 72% (P = 0.58) and need for fundoplication — 11%, 20%, 44% (*P = 0.02). There were no deaths related to the repair.ConclusionsMeasured gap length at the time of surgery did not have a linear relationship with leak or stricture rate. Our experience suggests that when primary repair is possible absolute gap length is irrelevant to the development of post-operative complications. There is however a significant increase in the need for fundoplication in those with a long gap. |
