Near-infrared fluorescence-assisted thoracoscopic diverticulectomy of esophageal diverticulum: a case report

Abstract

Background Esophageal diverticulum is a rare condition that requires treatment only when symptoms are present. Surgery has been considered to be the only curative option for symptomatic cases. The most popular procedure is diverticulectomy. Clear and intact exposure of the diverticulum’s neck is the basis for safe and effective diverticulectomy. Case presentation We herein report a case of a 57 year-old woman with an epiphrenic diverticulum. VATS diverticulectomy was scheduled. To better identify the diverticulum neck, we injected indocyanine green (ICG) into the diverticulum through the endoscopic channel, and the diverticulum wall and neck were clearly visible under near-infrared (NIR) fluorescence. With the help of this method, diverticulectomy was successfully performed. Conclusion This case shows that NIR fluorescence with ICG is safe, simple and reliable and can be used for diverticulectomy.
