Bronchiectasis consequent upon prolonged foreign body retention

To review our experience with bronchiectasis complicating prolonged endobronchial retention of foreign bodies (FB) among patients with a history of aspiration of FB seen between 1975 and 1998.

A retrospective review of clinical data of consecutive patients with a history of aspiration of FB treated during the time of study.

The Cardiothoracic Unit of the University College Hospital, Ibadan, directly serves a population of about 40 to 60 million in the South Western Nigeria and the community clinics.

All patients with a history of FB aspiration (or suggestive of FB aspiration) from whom patients with prolonged FB retention were selected.

Patients with a relevant history or chronic respiratory symptoms had their clinical examination findings, plain chest radiographic (or/and bronchographic) findings, treatment modalities and outcome studied.

Sixteen patients among 203 patients who had tracheobronchial foreign bodies removed had this complication. The mean age at presentation was 13.0 +/- 17.3 years. Twelve patients (75%) retained inorganic materials and in four patients (25%) it was organic. The period of retention ranged between 4.8 to 108 months (mean 17.0 +/- 22.6 months). Main presenting symptoms were: productive cough, 16 patients; pyrexia, seven patients; combination of chest pain, fever and copious sputum, five patients. In none of the patients was the history of aspiration of FB definitely elicited before commencement of treatment. Symptoms were worst among patients who retained inorganic materials. All of the patients had bronchoscopy but retrieval of FB by this means was successful in one patient (6.3%). Six patients (37.5%) had thoracotomy and bronchotomy; nine patients had bronchotomy and lung resection [seven (77.8%) lobectomies, one (11.1%) pneumonectomy and one (11.1%) segmentectomy] as the definitive treatment. The one patient who had brochoscopic retrieval subsequently had lobectomy to control symptoms of bronchiectasis. Five out of six (83.3%) who had bronchotomy had persistent symptoms of bronchiectasis. All the nine (56.3%) who had lung resection remained asymptomatic at follow up. There was one mortality (6.3%) in the series--a 75 year old who died from poorly controlled Diabetes mellitus.

Prevention of aspiration of FB is better than cure. In every medically treated child with persistent cough with or without a history of aspirated FB, the possibility of retained FB should be borne in mind.
