title: The approach of fused fissures with fissureless technique decreases the incidence of persistent air leak after lobectomy.
abstract: OBJECTIVE
  To evaluate two different approaches used to perform fused fissures in lobectomies in terms of persistent air leak (PAL) and their impact on length of hospital stay.
  
  
  METHODS
  One hundred and nineteen patients underwent lobectomy or bilobectomy in our unit. We focused on patients with fused fissures (63 patients), all of whom were selected intraoperatively based on predefined criteria. These patients with incomplete fissures were randomly assigned to two groups: Group A patients who underwent a 'traditional technique' to approach fused fissures and Group B patients who underwent a 'fissureless technique'. The latter technique avoids dissecting the lung parenchyma over the pulmonary artery, reducing the chances of air leak. Patients in both groups had shown no significant difference in preoperative variables (p>0.05).
  
  
  RESULTS
  The incidence of PAL was significantly higher among patients with incomplete or fused fissures (0 case vs 8 cases (Groups A and B), p<0.005). Furthermore, the incidence of PAL was significantly higher in the Group A (traditional technique) (7 vs 1) (p<0.05, OR=3.1, CI 0.22-0.51). The probability for air leak cessation was significantly higher in patients of Group B (fissureless technique) (log rank p<0.0001). The length of hospital stay was higher in Group A (5.76+/-3.1) compared with Group B (4.9+/-1.7) (p<0.05). No other variables were identified as risk factors for PAL in this series.
  
  
  CONCLUSIONS
  The fissureless technique appears to be a superior approach for fused fissures in terms of both preventing persistent air leak and reducing the length of hospitalisation. This technique can be performed safely at no additional cost and without adverse consequences.
