Robot‐assisted enucleation of a giant submucosal tumor in the upper esophagus

Few reports have demonstrated robotic surgery for large tumors in the upper esophagus. We report a case of a 52‐year‐old woman with a giant submucosal tumor in the upper esophagus successfully enucleated using robotic surgery. She presented with odynophagia and dysphagia, with subsequent evaluation revealing a submucosal mass measuring approximately 10 cm in diameter in the upper esophagus. The mass was compressing the trachea and enlarged over 3 years. Endoscopic ultrasound fine needle aspiration of the tumor was non‐diagnostic. Robot‐assisted esophageal submucosal tumor enucleation was performed for diagnosis and treatment. Flexible forceps control allowed for a multi‐directional approach to dissect the tumor and stable forceps handling was critical in this delicate procedure. Subsequent pathological review revealed a well‐differentiated esophageal liposarcoma. While surgical margins were not entirely negative, the local recurrence rate of the tumor is low. At the patient's request, we decided to observe the patient without additional resection.
