A Comparative Study of Video-Assisted Thoracic Surgery with Thoracotomy for Middle Lobe Syndrome.
The aim of this study is to evaluate the feasibility and safety of video-assisted thoracic surgery (VATS) for the treatment of middle lobe syndrome (MLS) through comparison with thoracotomy during the same period.



We retrospectively reviewed all consecutive patients with MLS who underwent lobectomy or lingular segmentectomy between December 2005 and November 2015 in a single institute. Thirty patients were enrolled and divided into two groups: VATS group (n = 19) and thoracotomy group (n = 11). Data regarding the patients' demographics, medical history were collected and statistically compared.



All patients received successful middle lobe resection or lingular segmentectomy. In terms of operation time, blood transfusion, chest drainage amount, duration of chest drainage and postoperative complications, no significant differences were found between the two groups (p > 0.05). The mean intraoperative blood loss of VATS group was less than thoracotomy group (79.0 ± 63.9 vs. 165 ± 94.9 ml, p = 0.04). In VATS group, the mean length of postoperative hospital stay was 6.0 ± 2.4 days, shorter than that in group thoracotomy (9.0 ± 3.5 days, p = 0.01).



VATS was a feasible and safe method for the surgical treatment of MLS in selected patients when no severe calcified lymph nodes surrounding hilus pulmonis was observed by preoperative chest CT scan.
