Balloon Dissection for Extra Pleural Approach in Tracheoesophageal Fistula Repair; A Novel Technique

Abstract

Objective: The extra-pleural approach for the tracheoesophageal fistula is preferred by most of pediatric surgeons because the possible substantial anastomotic leak will end in a fistula rather than an empyema. The problem with this technique that it is time consuming for pleural separation and liable for pleural tears. We studied a new method for using of Foley's catheter balloon to push the pleura away from the chest wall in an easier manner and shorter time. Method: A 25 neonate with tracheoesophageal fistula was managed with the extra-pleural approach using the Foley's catheter balloon as a method of pleural separation. Results: The mean time for pleural dissection was 4.5 m (266.4 sec) with a range of 2 m, 47 sec (167 sec) - 6 m, 18 sec (378 sec). Only 4 minor pleural tears were encountered (16%) that passed smoothly. 4 Anastomotic leaks occurred that were managed conservatively and 2 mild Anastomotic strictures (8%) occurred and were managed conservatively. Conclusion: Balloon dissection is a valuable addition to management of esophageal atresia. It accomplishes pleural separation from the rib cage in short time and easy manner with nearly 0% incidence of significant pleural tears. Moreover, it improves the outcome of possible postoperative anastomotic leak without adding to the patient's morbidity or the hospital cost.
