[Intraoperative neuromonitoring in thyroid surgery]. / Neuromonitorización intraoperatoria en cirugía tiroidea.

BACKGROUND: Intraoperative neuromonitoring of the recurrent laryngeal nerve in thyroid surgery facilitates the identification of anatomical structures in cervical endocrine surgery reducing the frequency of vocal cord paralysis. OBJECTIVE: To study the normal electrophysiological values of the vague and recurrent laryngeal nerves before and after thyroid surgery. To compare rates of injury of recurrent nerve before and after the introduction of the intraoperative neuromonitoring in thyroid surgery. MATERIAL AND METHODS: An observational, descriptive and prospective study in which a total of 490 patients were included. Between 2003-2010, surgery was performed on 411 patients (703 nerves at risk) with systematic identification of recurrent laryngeal nerves. Between 2010-2011 neuromonitorization was also systematically performed on 79 patients. RESULTS: Before the introduction of intraoperative neuromonitoring of 704 nerves at risk, there were 14 recurrent laryngeal nerve injuries. Since 2010, after the introduction of the intraoperative neuromonitoring in thyroid surgery, there has been no nerve injury in 135 nerves at risk. CONCLUSIONS: We consider the systematic identification of the recurrent laryngeal nerve is the 'gold standard' in thyroid surgery and the intraoperative neuromonitoring of nerves can never replace surgery but can complement it.

[Esophageal duplication cyst as an unusual cause of adult dysphagia]. / Quiste por duplicación esofágica como causa inusual de disfagia en el adulto.

Esophageal duplication cyst is a rare congenital alteration. Most of these cysts are asymptomatic and are usually identified as an incidental finding. These lesions can develop complications (bleeding, infection, etc.) and even malignant degeneration. Consequently, the treatment of choice is surgical.

El quiste por duplicación esofágica es una anomalía congénita poco frecuente. La mayoría de los casos son asintomáticos y su diagnóstico se establece habitualmente de forma incidental. La posibilidad de que se desarrollen complicaciones (hemorragia, infección, etc.) e incluso se malignicen hace que el tratamiento de elección de estas lesiones sea quirúrgico (AU)
