Glycopyrrolate as an Adjunct in the Management of Anastomotic Leak Following Repair of Esophageal Atresia: A Clinicoradiological Perspective.

Abstract

Anastomotic leak after primary repair of esophageal atresia (EA) with tracheoesophageal fistula (TEF) is a well-known complication and can represent a challenging clinical scenario. The present study aimed to evaluate the role of glycopyrrolate as an adjunct in the treatment of anastomotic leak after primary repair of EA Vogt type 3b. A retrospective study was carried out in our tertiary care teaching institute from January 2015 to December 2022. Neonates with EA with distal TEF with primary repair who had developed anastomotic leak, managed by the author(s), were studied. The study included patients with major, minor, and radiological leaks. Glycopyrrolate was administered in the dose of 4 μg/kg 8 hourly. The outcomes of the study were either resolution or progression of the leak. There were 21 patients who were managed with glycopyrrolate in addition to the classical treatment of the anastomotic leak following repair of EA with distal TEF. The male: female ratio was 1:1.1. All the cases had anastomotic leaks with either clinically detectable in the chest tube (15) or radiological leak (6). The leaks were detected early in patients with major leak (mean = 3.2 ± 0.84 days) compared to minor leak (mean =4.9 ± 1.29 days). Radiological leaks were detected in all the neonates on postoperative day 7. In five patients with major leak, there was a negligible reduction in the amount of chest tube output, and were subjected to diversion procedures. There were a total of three deaths out of five in this group. In 10 patients with minor leak, there was complete resolution of anastomotic leak in eight patients (80%); there was one patient each with mortality and diversion procedure. The patients with a radiological leak (6) did not show any deterioration, and they were fed 1-5 days after the esophagogram. Glycopyrrolate may be an advantageous postoperative adjunct in the management of minor and radiological leak after tracheoesophageal repair.
