Thoracoscopic enucleation of a large leiomyoma located on the left side of the esophageal wall

Surgical treatment of esophageal leiomyoma larger than 5 cm in diameter: A case report and review of the literature

Although leiomyoma is the most common benign esophageal neoplasm, it is a rare condition. Resection of the tumor is recommended in symptomatic patients, and observation is recommended in asymptomatic patients with small lesions. We discussed here a patient admitted to our hospital for dyspepsia in whom a calcified mediastinal neoplasm was diagnosised preoperatively and esophageal leiomyoma was diagnosised postoperatively. Enucleation of a leiomyoma of the esophagus is recommended and the optimal approaches should be tailored based on the location and size of the tumor.

Thoracoscopic enucleation of esophageal leiomyoma in patient with MEN I syndrome

Minimal invasive thoracic surgery is growing rapidly and may become the standard of care for certain diseases. Its benefits over traditional surgery, including reduced morbidities and hospital stay, have been well established in several reports. We herein report a case of midesophageal leiomyoma in a patient with MEN I syndrome successfully enucleated by thoracoscopy highlighting the technical details of the procedure.

Thoracoscopic enucleation of a gastrointestinal stromal tumor of the esophagus

Since the introduction of thoracoscopy in surgery, many thoracic interventions have been considered feasible and safe via the thoracoscopic route. We report the case of a 42-year-old man with a 7.5-cm esophageal gastrointestinal stromal tumor. Thoracoscopic enucleation of the tumor was performed and the patient was discharged on the third postoperative day after tolerating a full oral diet. Given the well-known advantages of minimally invasive surgery, we believe that removal of esophageal submucosal tumors can be attempted using a thoracoscopic approach, even if the tumor is large.

Enucleation of Esophageal Leiomyoma with Azygos Continuation of the Inferior Vena Cava: Report of a Case

We herein report a rare case of esophageal leiomyoma in an 18-year-old woman with azygos continuation of the inferior vena cava. A submucosal tumor was located in the left wall of the esophagus behind the carina. The enlarged azygos vein made video-assisted thoracic surgery so difficult that conversion to a minithoracotomy and transection of the right superior intercostal vein were necessary to fully visualize the tumor. A pathological diagnosis revealed leiomyoma. Our experience suggests that a transection of the right superior intercostal vein is effective for the proper exposure of an esophageal tumor located behind the carina in a patient with an enlarged azygos vein.

Thoracoscopic enucleation of a giant submucosal tumor of the esophagus

Since the introduction of thoracoscopy in the surgical field, many thoracic interventions have been considered feasible via thoracoscopic route. The authors reported a case of thoracoscopic enucleation of a giant esophageal submucosal tumor (8.5 cm in diameter) situated along the left side of the midesophagus. Histopathologic evaluation revealed a gastrointestinal stromal tumor (GIST). Postoperative period was uneventful and the patient was discharged on the eighth postoperative day. Given the well-known advantages of minimally invasive surgery, we assume that the removal of esophageal submucosal tumors can first be attempted by thoracoscopic approach, even if the tumor is of a big size. In cases of histopathologically unknown tumors preoperatively, definitive examination of the complete specimen provides the basis for further therapeutic decisions.

Enucleation of submucosal tumors of the esophagus: minimally invasive versus open approach

BACKGROUND

Surgical enucleation of submucosal tumors (SMTs) of the esophagus (mostly leiomyomas) is indicated when either the tumors are symptomatic or their biological behavior is unclear. The classic approach is a thoracotomy, but tumor enucleation can now also be performed via thoracoscopy or, for distal tumors, via laparoscopy.

METHODS

We assessed our experience with the different approaches in a total of 25 patients (n = 13 minimally invasive approach and n = 12 open surgery). Enucleation of the SMT was the basic surgical principle; the choice of the approach was based on the preference of the surgeon.

RESULTS

Compared to open surgery, the minimally invasive approach reduced pulmonary complications, hospital stay, and postoperative wound-related pain. The operating time was the same for both approaches.

CONCLUSION

Minimally invasive approaches are suitable for the surgical enucleation of submucosal esophageal tumors. Thoracoscopic and laparoscopic techniques are recommended as standard procedures in experienced centers.

Thoracoscopic enucleation of a leiomyoma of the upper thoracic esophagus

The authors present two cases of leiomyoma of the upper esophagus. Both of the cases presented with dysphagia, and one patient complained of pyrosis. An upper gastrointestinal endoscopy showed midesophageal narrowing without mucosal irregularity, suggestive of leiomyoma. The patients were successfully treated by thoracoscopic enucleation of the leiomyoma, using four thoracic trocars. In one patient (Case 1), the azygus vein had to be divided. Both of the patients are asymptomatic in the late-postoperative period.

Minimally invasive techniques for resection of benign esophageal tumors

With the emergence of minimally invasive surgery (MIS), laparoscopy and thoracoscopy have become feasible and safe alternatives to open surgical procedures in the management of esophageal leiomyomas. The indications for MIS resection of leiomyomas at our institution include the presence of symptoms, confirmation of pathology to exclude malignancy, tumors greater than 2 cm in size or tumors that show evidence of growth. Our approach of choice is right video-assisted thoracoscopic surgery (VATS) for tumors of the thoracic esophagus and laparoscopy for tumors of the intra-abdominal esophagus or gastroesophageal junction. A detailed description of these surgical approaches is outlined in the following chapter. At our institution, nine patients, 8 males and 2 females with a mean age of 54 years (range 42-67 years) had a minimally invasive surgical resection of an esophageal leiomyoma between 1995 and 2001. The surgical approaches included right VATS enucleation (6) and laparoscopic enucleation (3). There were no major morbidities, including postoperative leaks or mortalities. The mean hospital stay was 2.3 days. All tumors were benign leiomyomas with average size of 2.73 cm (range 0.9-8 cm) and there was no evidence of recurrence at a mean follow-up of 10 months. Video-assisted enucleation has shown in our institution, as well as in others, that the procedure can be performed safely with low mortality and morbidity. A VATS or laparoscopic approach to the removal of leiomyomas should be the treatment of choice in centers experienced in minimally invasive surgery.

Thoracoscopic resection of an esophageal stromal tumor through the left pleural cavity

We describe the technique for endoscopic removal of a stromal tumor of the lower third of the esophagus through the left thoracoscopic approach. The tumor resembled a leiomyoma and was classified as a borderline, potentially malignant lesion after thoracoscopic removal. The technique and clinical implications in such cases are discussed on the basis of current knowledge.

Thoracoscopic enucleation of an esophageal leiomyoma

A series of reports in the literature suggest that video assisted thoracoscopic resection of an esophageal leiomyoma offers distinct advantage over open approach. We describe a patient with esophageal leiomyoma who underwent surgical resection via thoracoscopic approach using four thoracic trocars. The postoperative period was uneventful and the patient was discharged on postoperative day 3.
