Esophageal Cancer with Tracheal Diverticulum: A Case Report

Abstract

A 63-year-old man with esophageal cancer was admitted to our hospital for post-operative endoscopic submucosal dissection. He needed additional resection of the esophagus due to submucosal (SM) invasion. The preoperative diagnosis was cT1b cN0 M0 cStage Ⅰ, cystic emphysema in the trachea, which was found to be a tracheal diverticulum. The patient underwent video-assisted thoracoscopic surgery of the esophagus after neoadjuvant chemotherapy. The diverticulum was located dorsally on the right side of the trachea. Although it often swelled up with intraoperative ventilation, there was no adhesion around the diverticulum, and the operation was completed without damaging it. Examples of esophageal cancer with tracheal diverticulum are few in Japan. This report is significant because it provides useful information regarding an effective and safe esophageal cancer surgery.
