Bronchoesophageal Fistula Repair with Intercostal Muscle Flap Followed by Occlusion of Residual Diverticula with N-butyl Cyanoacrylate (NBCA) Glue: A Case Report.

The incidence of bronchoesophageal fistula in presence of benign pathology of tracheal tree or oesophagus is rare. It is encountered in thoracic diseases like tuberculosis, syphilis or histoplasmosis due to erosion by infected lymph node or abscess to adjoining structures. The source of primary pathology has to be eliminated followed by appropriate steps of fistula tract closure is essential for optimal result. We report a 25-year-old patient with left sided bronchoesophageal fistula. He had a past history of pulmonary tuberculosis. A left lower lobectomy followed by repair of oesophageal fistula opening was performed by primary closure and reinforcement with an intercostal muscle flap based on posterior intercostal artery. Postoperative oesophagogram showed short diverticula, which was occluded with n-butyl cyanoacrylate (NBCA) glue under radiological guidance. Feeding was started one week after application of glue without further complication. Reports on intercostals muscle flap repair and intervention of residual oesophageal diverticula with n-butyl cyanoacrylate (NBCA) glue under radiological guidance are scanty.
