Direct observation diverticulectomy for Zenker’s diverticulum carcinoma

Zenker’s diverticulum carcinoma is a rare disease. Recent technological endoscopic innovation has enabled the detection of early stage Zenker’s diverticulum carcinoma. Here we report a case in which a 56-year-old woman was diagnosed with early stage Zenker’s diverticulum carcinoma. Narrow band imaging (NBI) endoscopic examination was useful for diagnosis and identifying the borders of the carcinoma. A successful surgical treatment was performed using direct observation diverticulectomy. A minimally invasive cervical procedure was used, and the area of the carcinoma was confirmed intraoperatively with Lugol’s solution.
