Both primary and secondary pulmonary abscesses are increasingly observed in
thoracic surgery units. Primary pulmonary abscesses are related to necroti
sing pneumonia or aspiration due to alcoholism, drug abuse, dysphagia or ga
strointestinal reflux disease. Secondary poststenotic abscesses are related
to bronchial obstruction (endobronchial tumour or foreign body aspiration)
or to superinfection of pulmonary neoplasia or infarction pneumonia. Bronc
hoscopy is mandatory ifa pulmonary abscess is suspected, to exclude endobro
nchial obstruction and obtain bacteriological examination by bronchial lava
ge or transbronchial fine needle aspiration. Transthoracic fine needle aspi
ration may be helpful for bacteriological examination, since germs found in
sputum do not necessarily correlate with those found in the abscess. Pulmo
nary abscesses are primarily treated by administration of appropriate antib
iotics with a remission rate of 80%. In the presence of complications of th
e abscess or if conservative management fails, percutaneous transthoracic d
rainage or surgical resection may be indicated.
Bronchiectasis is also increasingly seen, especially in refugees and immigr
ants. The disease is characterised by chronic dilatation of bronchi with pa
roxysmal cough, mucopurulent secretion and recurrent pulmonary infections.
Bronchiectasis is most commonly caused by recurrent bronchial infections du
ring childhood or behind bronchial obstruction. Congenital bronchiectasis i
s very rare. Viral and bacterial pulmonary infections during childhood are
by far the most common causes of bronchiectasis, leading to destruction of
the mucociliary apparatus and the cartilage of the segmental bronchi. Bronc
hiectasis should be treated by an appropriate antibiotic regimen. Resection
should only be considered in situations where a conservative regimen fails
. Segmentectomy of all involved segments is the surgical treatment of choic
e in situations with well-localised bronchiectasis and results in long-last
ing remission in over 80% of those patients. Patients with bilateral bronch
iectasis may be considered for bilateral surgical resection if diffuse and
congenital disease has been ruled out.
