OBJECTIVES: Middle lobe syndrome is a well-known clinical condition. In this retrospective study, we report our experience with a similar clinicopathological condition affecting the left lower lobe.
METHODS: The data of 17 patients with atelectasis or bronchiectasis of the left lower lobe who underwent lobectomy during the period from January 2000 to December 2011 were reviewed. Demographic, clinical, radiological and surgical data were collected.
RESULTS: Seventeen patients were included in this study, only one adult male patient of 52 years and 16 children. The paediatric patients were 10 boys and 6 girls, their age ranged from 2 to 11 years, mean 6.19 ± 2.6 years. Most patients presented with recurrent respiratory infection 15/17 (88.2%). The lag time before referral to surgery ranged from 3 to 48 months, mean 17.59 ± 13.1 months. Radiological signs of bronchiectasis were found in 11 (64.7%) patients. Bronchoscopy showed patent lower lobe bronchus in all patients. The criteria for lobectomy were evidence of bronchiectasis [11 (64.71%) patients], persistent atelectasis of the lobe after bronchoscopy and intensive medical therapy for a maximum of 2 months [6 (35.29%) patients]. Histopathological examination showed bronchiectasis in 11 (64.71%) patients, fibrosing pneumonitis in 4 (23.53%) patients and peribronchial inflammation in 2 (11.76%) patients. Most patients were doing well 1 year after surgery.
CONCLUSIONS: Chronic atelectasis of the left lower lobe is a clinicopathological condition equivalent to middle lobe syndrome. Impaired collateral ventilation together with airway plugging with secretion is an accepted explanation. Surgical resection is indicated for bronchiectatic lobe or failure of 2-month intensive medical therapy to resolve lobar atelectasis.
