  • Neoesophagus From Colonic Interposition

    A 54-year-old man with a history of dysphagia and pacemaker placement for structural heart disease presented with left facial cellulitis and Streptococcus parasanguinis bacteremia. He required transesophageal echocardiography (TEE) for further assessment after a questionable vegetation had been seen on a 2-dimensional echocardiogram.

    During TEE, the gastroenterology team was consulted after the cardiology team had difficulty advancing the endoscope beyond 30 cm on multiple attempts. Endoscopy was performed, the results of which revealed that the esophagus was surgically absent, and that the patient had a pharyngeal-colonic anastomosis (figure).

    An 80-year-old man underwent a colonoscopy as part of postoperative surveillance.
