A case of esophageal cancer in a diverticulum treated by surgical resection: a case report

Abstract

BackgroundAn esophageal diverticulum is a relatively rare disease, with reports of treatment for esophageal cancer in the diverticulum even rarer.Case presentationThe case involved a 72-year-old male with a chief complaint of dysphagia. He was diagnosed with an esophageal diverticulum (Zenker’s diverticulum) measuring 10 cm in diameter. Five years later, an upper gastrointestinal endoscopy revealed an iodine-unstained 0–IIb lesion of 20 mm in diameter with type B1 vessels in the diverticulum. An endoscopic biopsy and CT revealed it to be squamous cell carcinoma, cT1a-EP/LPM N0 M0, cStage 0. Because the lesion was in the diverticulum and endoscopic resection was difficult with the risk of perforation, surgical resection was set as the course of treatment. Diverticulectomy was performed via a cervical approach, using a stapler, and the patient was discharged on the 16th day without any complications. The pathological diagnosis was pTis-EP, ly0, v0, R0.ConclusionsWe think this case is very rare and diverticulectomy of early esophageal cancer in the diverticulum is available and safe.
