Abstract

Aims: We are reporting single-institution's experience regarding the role of conservative management in 38 cases of minor and major anastomotic leaks [AL] occurring after primary surgery of esophageal atresia [EA] with tracheo-esophageal fistula [TEF] during last 17 years between 2000 and 2017. In this retrospective review, we are sharing our experience and protocol of management of AL with more emphasis to evaluate: (a) role of conservative treatment in major AL (b) role of extra-pleural approach in enhancing the success rate in conservative treatment in major AL (c) to define the criteria for major & minor leaks and (d) to evaluate the role of ventilation in primary EA surgery to control AL.

Methods: All these cases were operated through extra-pleural approach and out of total 203 cases, 38[18.7%] developed anastomotic leaks. In 29 of the 38 cases [14.3%], leak was minor and in 9 cases [4.4%] the leak was a major one. All these cases of leaks were managed conservatively.

Results: All cases of major and minor leaks showed spontaneous healing except one case of minor leak that died before healing due to major cardiac anomaly. For minor leaks, average healing time was 9.5 days while for major leaks it was 17.4 days. Overall mortality was 14.8% and there was no mortality directly attributable to major or minor leak. During follow up, the incidence of stricture was 40% in cases having anastomotic leaks, while in cases without a leak, the incidence of stricture was 23.3%. These all cases of stricture responded to regular dilatations.

Conclusion: We believe in cases of major AL, where primary repair is done by EP approach, a conservative treatment should be the treatment of choice. With this conservative approach of management of major AL, we not only save the native esophagus, the best conduit, but there is also less morbidity and mortality.
