The value of intraoperative bronchoscopic inspection (IBI) for accurate confirmation of the location and distance between the distal tracheoesophageal fistula (TEF) and the proximal blind end of the esophagus (GAP) was evaluated in Type C esophageal atresia (EA)+TEF. IBI involved inserting the tip of a bronchoscope into the TEF and a nasogastric tube into the blind end of the EA and measuring GAP with fluoroscopy. EA+TEF patients (  = 23) treated thoracoscopically between 2007 and 2020 were classified according to IBI as IBI+ (  = 16) and IBI- (  = 7) to compare demographics, operative time, and time taken for TEF division. Demographics were similar. Mean time for TEF division (15.4 ± 4.6 minutes for IBI+ versus 38.6 ± 20.9 minutes for IBI-;  < .05) and mean operative time (215.3 ± 48.9 minutes for IBI+ versus 286.4 ± 51.7 minutes for IBI+;  < .05) were significantly shorter. Mean GAP measured radiographically was 0.5 cm (range: 0-1.2 cm); mean GAP measured with IBI was 0.9 cm (range: 0-2.2 cm). Postoperative complications were 3 anastomotic leakages (1/16 in IBI+ and 2/7 in IBI-) that resolved without surgery and 8 strictures (3/16 in IBI+ and 5/7 in IBI-) treated by dilatation. IBI was effective for measuring GAP and is recommended for improving the efficiency of thoracoscopic repair.
