Thoracoscopic Esophageal Atresia Repair: Outcomes Analysis Between Primary and Staged Procedures.

PURPOSE Thoracoscopic repair of esophageal atresia (EA) is analyzed in this systematic review that compares outcomes between primary and staged repairs. MATERIALS AND METHODS PubMed/Embase databases were reviewed for articles on thoracoscopic repair of EA, and articles were selected for primary and staged repairs. Descriptive statistics were used to analyze the quantitative parts of the study. RESULTS Thirty-six articles identified between 1999 and 2019 met the inclusion criteria and offered 776 patients for this analysis. Primary repairs were performed in n=703 and staged repairs in n=73. Comparative analysis showed that esophageal anastomosis was performed using absorbable suture in 88% primary and 78% staged repairs. Anastomotic leak rates were comparable between primary n=65/696 (9%) and staged repairs n=8/73 (11%). The re-fistulation rate was 2% in primary and 1% in staged repairs. There was no difference between suture material and re-fistulation (P>0.05; NS). In primary repairs, nonabsorbable sutures were found to be associated with more leaks than absorbable sutures (P<0.05*). The conversion rate was similar between 2 approaches; primary n=49/680 (7%) and staged n=6/73 (8%); P>0.05. No significant differences were found in the rate of anastomosis strictures between primary n=135/703 (19%) and staged repair n=21/73 (29%); P>0.05. The overall mortality was n=20/703 (3%) in primary and n=1/73 (1%) in staged repairs; P>0.05. CONCLUSIONS Successful thoracoscopic primary- and staged-EA repairs have been reported with low rate of complications. Outcomes between primary and staged repairs do not show significant differences with regards to re-fistulation, anastomotic leaks, conversion rates, and mortality.
