_Mortality and morbidity of bronchoscopy_ vary directly with the degree of skill and experience of the operator, and the conditions for which the endoscopies are performed. The simple insertion of the bronchoscope is devoid of harm if carefully done. The danger lies in misdirected efforts at removal of the intruder and in repeating bronchoscopies in children at too frequent intervals, or in prolonging the procedure unduly. In children under one year endoscopy should be limited to twenty minutes, and should not be repeated sooner than one week after, unless urgently indicated. A child of 5 years will bear 40 to 60 minutes work, while the adult offers no unvarying time limit. More can be ultimately accomplished, and less reaction will follow short endoscopies repeated at proper intervals than in one long procedure. _Indications for bronchoscopy for suspected foreign body_ may be thus summarized: 1. The appearance of a suspicious shadow in the radiograph, in the line of a bronchus. 2. In any case in which lung symptoms followed a clear history of the patient having choked on a foreign body. 3. In any case showing signs of obstruction in the trachea or of a bronchus. 4. In suspected bronchiectasis. 5. Symptoms of pulmonary tuberculosis with sputum constantly negative for tubercle bacilli. If the physical signs are at the base, particularly the right base, the indication becomes very strong even in the absence of any foreign body circumstance in the history. 6. In all cases of doubt, bronchoscopy should be done anyway. There is no absolute _contraindication to bronchoscopy for foreign bodies_. Extreme exhaustion or reaction from previous efforts at removal may call for delay for recuperation, but pulmonary abscess and even the rarer complications, bronchopneumonia and gangrene of the lung, are improved by the early removal of the foreign body.
