INTRODUCTION: Leiomyomas are the commonest benign esophageal neoplasms. Surgical treatment is the therapy of choice for such tumors. Open enucleation via thoracotomy has long been the standard procedure. With the emergence of thoracoscopic and laparoscopic approaches, minimally invasive surgery represent interesting alternatives to open surgical procedures. AIM: To propose endoscopic technique for the treatment of these myomas avoiding thoracotomy. TECHNIQUE: Enucleation of leiomyoma by: A) thoracoscopy, for thoracic esophageal tumors, or B) laparoscopy to the ones located in abdominal esophagus. A) The operations are performed under general anesthesia with selective intubation of the left lung. Patients are placed in the left lateral decubitus position and mild dorsiflexion. Four work trocars are used, two of 11 mm and two of 5 mm. One of the 11 mm is put in the 6th intercostal space in the posterior axillary line to use the 30° endoscope; another, at the same hemi-clavicular line, to take the lung away off surgical site. Other two trocars of 5 mm are installed for working tools of the surgeon, one in the 4th space in the posterior axillary line, and another in the 7th, also in the posterior axillary line. Operations are always initiated by opening the mediastinal pleura, dissection of the tumor with opening the muscle of the esophageal wall, simple enucleation of the tumor and closure of esophageal parietal muscular layer. B) The interventions are done with patients undergoing general anesthesia and placed in the French position. The approach is the same performed to correct the hiatal hernia, and enucleation is done without difficulty. CONCLUSION: Videosurgery for leiomyomas resection is safe and feasible and provides results similar to open procedure, but with a significant reduction in morbidity.
