Abstract

Objective:

Minimally invasive esophagectomy (MIE) is increasingly used for the treatment of esophageal cancer. However, MIE via the Sweet approach has seldom been reported owing to the challenging procedure for a mediastinal lymph node. Thus, the approach of MIE via left-sided thoracoscopy coupled with video-assisted cervical mediastinoscopy (MIE-SM) was explored for eradicating the mediastinal lymph nodes and recurrent laryngeal nerve; the incidence of perioperative complications, mortality, and surgical radicality were analyzed.

Materials and Methods:

Thirty patients with esophageal carcinoma underwent MIE-SM between June 2014 and February 2016. The primary outcome was postoperative morbidity within 2 weeks postsurgery. The secondary outcome was surgical radicality, including the circumferential margins, and the number of lymph nodes dissected.

Results:

The MIE-SM was completed in all patients within 367.6±68.7 minutes. The incidences of postoperative morbidities including pulmonary complications, anastomotic leakage, chylothorax, or recurrent nerve injury were 43.3%.

Conclusion:

The MIE-SM was utilized for the first time to reduce the disadvantage of purely Sweet and McKeown approach, with favorable efficacy in the mediastinal and laryngeal recurrent nerve lymph node eradication. Thus, MIE-SM might be a promising alternative approach in treating esophageal cancer in selected patients.
