From: Esophageal pulmonary fistula – a rare complication of radiation therapy: a case report
(a) Endoscopic view of the upper esophagus visualizes the origin of the esophagopulmonary fistula (arrowhead) on the left site of the esophagus lumen (arrow). (b) Endoscopic view after treatment illustrates how the fistula was managed with a fully covered self-expandable metallic stent. (c) Radioscopic control after stent deployment proves the fistulous tract to be excluded, with no esophagopulmonary contrast leakage
