title: Pleural tent after upper lobectomy: a prospective randomized study.
abstract: BACKGROUND
  The aim of the present study was to assess the cost/efficacy of the pleural tent procedure after upper lobectomy.
  
  
  METHODS
  A prospective randomized analysis was performed on 50 patients submitted to upper lobectomy and divided into two groups: group 1 (25 patients) with pleural tent; group 2 (25 patients) without pleural tent.
  
  
  RESULTS
  The univariate comparison between the two groups did not show any significant difference in terms of age, gender, spirometry, smoking history, chronic obstructive pulmonary disease index, side of tumor, arterial oxygen tension, arterial carbon dioxide tension, size and location of tumor, presence of pleural adhesions, length of the stapled parenchyma, and operative time. Pleural tent significantly reduced the days of postoperative air leak (1.2 versus 5.8, p = 0.01), chest tubes (5.4 versus 10.4, p = 0.01), and hospital stay (6.9 versus 10.8, p = 0.01). Moreover, no difference was noted between the two groups in terms of pleural effusion in the first postoperative 48 hours, need of postoperative blood transfusion, and occurrence of other complications.
  
  
  CONCLUSIONS
  Pleural tenting after upper lobectomy is a safe and effective procedure and its routine use is warranted.
