Introduction: Surgical treatment of esophageal cancer is associated with high morbidity and mortality. The minimally invasive approach has been introduced with the aim of reducing postoperative morbidity. Aim: To describe the surgical technique and the results of transthoracic minimally invasive esophagectomy (MIE) in semiprone position. Material and Methods: Descriptive cohort study. Patients with an elective MIE for cancer were included between April 2013 and May 2017. Demographic, perioperative, pathology and survival variables were recorded. Results: We included 33 patients (24 men, age 69 years, 91% with comorbidities). The predominant location of the tumor was in the middle and lower thirds of the esophagus (90%). Fifteen (45%) patients received neoadjuvant treatment. There were no cases of conversion to thoracotomy. The reconstruction was performed with stomach in 93%. Cervical anastomosis was performed in 66% and thoracic anastomosis in 30%. The operative time was 420 (330-570) minutes and bleeding 200 (20-700) cc. The 90-day mortality rate was 0%. Overall morbidity was 78%, there was a 15% occurrence of pneumonia and 9% required a reoperation. The hospital stay was 23 (11-81) days. The histology was squamous carcinoma in 51% and adenocarcinoma in 45%. Margins were RO at 87%. The lymph node count reached 30 (9-45) lymph nodes. Overall 2-year survival is 68%. Conclusion: The preliminary results of this technique are favorable, without any case of postoperative mortality. The oncological results demonstrate a high percentage of RO surgery and adequate lymph node count.Introducción: El tratamiento quirúrgico del cáncer esofágico se asocia a una alta morbimortalidad. El abordaje mínimamente invasivo se ha introducido con el objetivo de disminuir la morbilidad postoperatoria. Objetivo: Describir la técnica y los resultados de la esofagectomía mínimamente invasiva (EMI) transtorácica en posición semiprono. Métodos: Estudio de cohorte descriptivo. Se incluyeron pacientes con una EMI electiva por cáncer entre abril de 2013 y mayo de 2017. Se registraron variables demográficas, perioperatorias, anatomía patológica y la sobrevida. Resultados: Incluimos 33 pacientes (24 hombres, edad 69 años, 91% con comorbilidades). La ubicación predominante del tumor fue en los tercios medio e inferior del esófago (90%). Quince (45%) pacientes recibieron neoadyuvancia. No existieron casos de conversión a toracotomías. La reconstrucción se realizó con estómago en un 93%. Se realizó anastomosis cervical en 66% y torácica en 30%. El tiempo operatorio fue de 420 (330-570) minutos y el sangrado de 200 (20-700) cc. La mortalidad a 90 días fue de 0%. La morbilidad global fue de 78%, se registró un 15% de neumonía y un 9% requirió una reoperación. La estadía hospitalaria fue de 23 (11-81) días. La histología fue carcinoma escamoso en 51% y adenocarcinoma en 45%. Los márgenes fueron RO en 87%. El recuento ganglionar alcanzó 30 (9-45) ganglios. La sobrevida global a 2 años es 68%. Conclusión: Los resultados preliminares de esta técnica son ...
