Summary:This case report describes a successful outcome of mirtazapine treatment in a patient with difficult post-thoracotomy pain. A 63-year-old man received thoracotomy for the resection of esophageal tumor. The pain continued 2 years after the operation. Allodynia was present in the region of the intercostal nerves from the surgical wound. Remedies such as clonazepam, amitriptyline, gabapentin, and acetaminophen were not effective, and epidural block effect was only temporal. The patient experienced a reduction in shooting pain after taking pregabalin; however, he still suffered from persistent pain and, mirtazapine was additionally administrated. One month after this, shooting and persistent pain was reduced, and the patient's appetite was improved, which had been present since the thoracotomy. Since then, his weight slightly increased and the administration of mirtazapine was stopped in accordance with the patient's request. The pain became worse again. Therefore, mirtazapine, commonly used as an antidepressant agent, was considered to be beneficial for neuropathic pain as an analgesic adjuvant.
