Is thoracoscopic esophageal atresia repair safe in the presence of cardiac anomalies?

BACKGROUND

Esophageal atresia (EA) is often associated with congenital heart disease (CHD). Repair of EA by the thoracoscopic approach places physiological stress on a newborn with CHD. This paper reviews the outcomes of infants with CHD who had undergone thoracoscopic EA repair, comparing their outcomes to those without CHD.

METHODS

This was a review of infants who underwent thoracoscopic EA repair from 2009 to 2017 at one institution. Operative time and outcomes were analyzed in relation to CHD status.

RESULTS

Twenty five infants underwent thoracoscopic EA repair during the study period. Seventeen (68%) had associated anomalies of whom 9 (36%) had cardiac anomalies. The mean operative time was 217 min. There was no difference in operative time between CHD and non-CHD cases (estimate 20 min longer operative time in the presence of a cardiac anomaly [95% CI -20 to 57]). Two cases were converted to open thoracotomy; both were non-CHD. There was no difference in the time to feeding, time in intensive care unit or time in hospital between CHD and non-CHD cases. Five patients developed an anastomotic leak (two CHD and three non-CHD) of which two were clinical; all were managed conservatively. There was no case of recurrent fistula.

CONCLUSIONS

This pilot study did not find evidence that thoracoscopic EA repair compromised outcomes in children with congenital heart disease. A prospective multicenter study with long-term follow-up is recommended to confirm whether thoracoscopic repair in CHD is truly equivalent to the open operation.

TYPE OF STUDY: Therapeutic.

LEVEL OF EVIDENCE: Level III.
