Modified method of primary esophageal anastomosis with improved outcome in cases of esophageal atresia with tracheoesophageal fistula.

Survival rates for infants who have esophageal atresia (EA) with or without fistula (TEF) have improved dramatically in the past 50 years. Despite excellent long-term survival for patients with esophageal atresia with tracheoesophageal fistula (EA-TEF), many significant complications can occur. Anastomotic leak at the esophagoesophagostomy site is one such problem resulting in considerable morbidity and mortality in these patients. The methods of esophageal anastomosis for long period has remained the simple end to end anastomosis of esophageal ends with various modifications described from time to time. The present study aims to study the effect on the early postoperative complications, following horizontal mattress suture technique on the primary esophageal anastomosis in cases of EA-TEF. A total of 32 patients with EA-TEF, were operated by our technique during a period of 1 year (2007-2008). The results were compared with the patients (n = 66), who were operated by the traditional simple technique during the same period. Among those patients in whom the esophageal anastomosis was done by horizontal mattress suture, only one had major anastomotic leak, while two had minor anastomotic leaks, as compared to six and nine cases correspondingly in other patients in whom anastomosis was done by simple technique. There was single mortality. We propose that, the utilization of our technique of horizontal mattress suture in primary anastomosis of esophagus in cases of EA-TEF significantly reduces the risk of anastomotic leaks and subsequent morbidity and mortality.
