Comparison between use of a pleural drainage system with flutter valve and a conventional water-seal drainage system after lung resection: a randomized prospective study.

Background: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications.

Objectives: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber.

Design And Setting: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil.

Morbidity, mortality, and categorization of the risk of perioperative complications in lung cancer patients.

Objective: To determine morbidity and mortality rates by risk category in accordance with the American College of Chest Physicians guidelines, to determine what role pulmonary function tests play in this categorization process, and to identify risk factors for perioperative complications (PCs).

Methods: This was a historical cohort study based on preoperative and postoperative data collected for cases of lung cancer diagnosed or suspected between 2001 and 2010.

Results: Of the 239 patients evaluated, only 13 (5.
