Mesothelioma Diagnosis: Bronchoscopy
A bronchoscopy is a diagnostic procedure in which a
viewing device, known as a bronchoscope, is inserted into a
person’s airways through the mouth. A bronchoscope contains
a small camera that allows for visual examination of the
lower airways. Depending on the scope of the bronchoscopy
that will be performed, doctors can choose between two types
of bronchoscopes. One is a flexible fiber optic scope used
for more delicate procedures. The second, which is wider and
rigid, is used to remove foreign objects from the windpipe
and lungs. When a bronchoscopy is performed to remove
obstructions from a person’s airways, it is considered a
therapeutic, rather than a diagnostic, procedure.
Purpose
A bronchoscopy is used to examine the lower airways, to
examine mucosal surfaces for signs of cancer, to check for
obstructions or tumors, and to perform biopsies or surgery.
It is a commonly-used procedure in patients who present with
some form of pulmonary distress, such as the restricted
breathing (“dyspnea”) commonly associated with
malignant mesothelioma and other lung-related deficiencies.
Bronchoscopy and Mesothelioma Diagnosis
When it is uncertain whether patients have
pleural
mesothelioma, or another tumor or abnormality in the lungs
or related-areas, a bronchoscopy may be recommended to avoid
unneeded surgery. For patients who display signs of pleural
mesothelioma, a bronchoscopy may be ordered to take a biopsy
of the affected areas.
Preparation
Patients should not eat or drink after midnight on the
night before surgery. Doctors should be notified of any and
all allergies and medications being used.
Procedure
A bronchoscopy is usually performed with a local
anesthetic. The procedure requires the patient to either lie
on their back face up, or to sit upright in a chair. The
bronchoscope is inserted either through the nasal passage or
through the mouth and down the throat. Patients who have
trouble breathing may be assisted by a respirator during the
procedure.
A bronchial brush, a needle or forceps may be used to
obtain tissue samples. A procedure called fluorescence
bronchoscopy may also be used. This involves the use of a
fluorescent light in the bronchoscope that displays
precancerous tissue as dark red and healthy tissue as green.
Risks
The procedure carries several risks. Those include vocal
cord damage, esophageal abrasions, spasms of the bronchial
tubes, irregular heart rhythms and infection. With
contemporary techniques, however, the incidence of these
side effects has been greatly reduced and bronchoscopy is
considered a safe procedure.
After Care
A bronchoscopy is an outpatient procedure. After the
bronchoscopy, a patient’s heart rate, blood pressure and
breathing are monitored. Saliva is examined for any sign of
bleeding. No food or drink should be eaten for two to four
hours after the procedure. Patients who receive a biopsy
should not clear their throat or cough, as this can dislodge
blood clots and cause bleeding.
