Abstract:
Objective: To discuss the imaging features of esophageal fistula and the value of intervention.Methods: We retrospectively analyzed the complete clinical data of 12 cases of esophageal fistula treated from June 2000 to May 2008,of whom,2 developed esophago-thoracis fistula and esophago-mediastinum fistula respectively after conservative radiotherapy,and 10 developed esophageal fistula after surgery for esophageal cancer.All the patients received iodine-based oral contrast,spiral CT scanning and intraperitoneal stent implantation for fistula closure.Results: Iodine-based oral contrast showed that the contrast agent overflowed into the chest in 8 cases,into the airway in 3 and into the mediastinum in 1.Spiral CT scanning revealed 8 cases of pleural fistula and 2 cases of remnant stomach-airway fistula,but failed to display the other 2 because of the small size.Intraperitoneal stent implantation was successfully accomplished in all the cases,which helped to close the fistula,take in food,stop bucking,control lung,mediastinum and other infections,and improve the patients' quality of life.Conclusion: Esophageal fistula can be effectively diagnosed based on the findings of iodine-based oral contrast and spiral CT scanning.As a novel technique,intraperitoneal stent implantation for fistula closure,simple,safe and with obvious immediate effect,is well worth promoting.
