Material and method• Retrospective study – January 2013 – August 2015 (32

months)• Patients undergoing anatomic lung resections• 172 resections analysed

• 31 (18,02%) pneumonectomies• 5 (2,91%) bilobectomies• 136 (79,06%) lobectomies

Results• 36 (20,93%) patients with complications • 3 (1,74%) postoperative deaths due to complications• General complications:

• 3 (1,74%) postoperative arrythmias• 1 (0,58%) postoperative stroke

• Pleuro-pulmonary complications:• 7 (4,06%) bronchial stump fistulas• 8 (4,65%) pneumonias on the remaining parenchyma• 1 (0,58%) empyema without fistula• 1 (0,58%) chylothorax• 11 (6,38%) persistent air leaks requiring hospital stays longer than

14 days• 3 (1,74%) haemothorax requiring an iterative surgical procedure

Results• 31 male patients and 5 female patients

Discussion• 30 days postoperative mortality:

• 6-20% after pneumonectomies1

• 3-8 % after lebectomies1

• our experience - 1,74%

• Postoperative morbidity – up to 60%1

• our experience – 20,93%• neoadjuvant therapy?

• Morbidity and mortality prediction scores2

Discussion• Bleeding complications:

• 0,1 – 3% following thoracotomies• less than 2% following thoracoscopies• our experience – 1,74% - haemothorax – iterative surgery

• Cardiac complications:• arrhythmias – 35%• myocardial infarction - 3,8%• cardiac herniation – immediately after surgery - 50% mortality• our experience – 1,74% arrhythmias, no myocardial infarction

• Phrenic and recurrential lessions – 1% - none in our experience• In our experience – 1 stroke

Discussion• Postpneumonectomy pulmonary edema – 2-5%• Prolonged air leak, severe subcutaneous emphysema – 50% - if

severe “Michelin syndrome”• our experience - 11 (6,38%) persistent air leaks requiring hospital stays

longer than 14 days• intra-operative control of bronchial stump• early extubation – intra-alveolar pressure

• Lobar torsion – less than 0,5%• none in our experience – regular preventive fixation of the remaining lobes• reintervention indicated – emboli spread after untwisting – intrapericardic

clamping of pulmonary veins recommended

Discussion• Empyema – 2-12% in the literature

• our experience – 1 (0,58%) empyema without fistula on control bronchoscopy

• culture of pleural fluid before antibiotics• adequate chest tube drainage required

• Bronchial stump fistulas – incidence varies across literature• our experience – 7 (4,06%) bronchial stump fistulas

• 3 surgical revisions of the bronchial stump:• 1 pneumonectomy• 1 resection and closure of the bronchial stump• 1 bronchial stump plasty with serratus muscle

• 4 bronchoscopically sealed bronchial stump fistulas

Discussion

• Particular pleuro-pulmonary complications we encoutered:• 1 (0,58%) chylothorax after the surgical treatment of a Stocker type

II adenomatoid cystic malformation in an adult (41 years old)

Conclusion

• Our experience so far is comparable to the data provided in the current literature

• Postoperative complications – survival differences• Deficiencies in healing

• Neoadjuvant therapy• Age
