Profile of repeat fiberoptic bronchoscopy.
BACKGROUND
Fiberoptic bronchoscopy (FOB) is invaluable in the diagnosis of a variety of pulmonary diseases, but in many instances the procedure has to be repeated because of an inconclusive initial FOB or for reassessment.


METHODS
A retrospective analysis of all the fiberoptic bronchoscopic procedures done between September 2000 and February 2003 was performed and details of patients undergoing repeat FOB abstracted.


RESULTS
Of the 2,270 bronchoscopies performed on 2114 patients, 132 procedures were repeated, yielding an over all frequency of repeat FOB of 6.34 percent. Bronchoscopy was done twice in 112 patients, thrice in 16 patients and four times in four patients. The commonest diagnosis in patients undergoing repeat bronchoscopy was bronchogenic carcinoma, followed by non-resolving pneumonia or presence of pulmonary infiltrates in immunocompromised host. The major indications for repeating FOB included obtaining specimens for pathological examination, pre and postoperative evaluation of airways, localization of site of bleeding in patients with hemoptysis, and placement of catheters for intraluminal brachytherapy. Of the 88 cases undergoing repeat bronchoscopy for diagnostic purposes, 41 (46.6%) yielded positive results, either in form of positive histology or localisation of source of hemoptysis.


CONCLUSIONS
The frequency of repeat bronchoscopy was low. Commonest indication for a repeat procedure was to obtain repeat/additional diagnostic samples. A repeat procedure can yield positive results even when the initial FOB is nondiagnostic.
