[Endoscopic pointing device for virtual bronchoscopy].

Abstract

Virtual bronchoscopy is useful for understanding the morphology of tracheobronchial space. Because it is difficult to operate the system, we developed a new pointing device simulating the grip of a flexible bronchofiberscope. With this device, it was possible to simulate the handling of a bronchofiberscope (in or out, clockwise or counterclockwise rotation, arbitrary angle of view). We conclude this type of pointing device could prove to be a useful tool in endoscopic simulation.

Management of distal tracheal stenosis.

OBJECTIVE: To evaluate the treatment, perioperative management, and outcome of infants who underwent repair of congenital tracheal stenosis. We hypothesized that early resection and tracheoplasty with early weaning of ventilatory support results in less mucosal injury, and thus better outcome. DESIGN: Retrospective study from 1986 to 1996. SETTING: Tertiary care children's hospital. PATIENTS: Seventeen consecutive infants with congenital tracheal stenosis, aged from birth to 16 months. Fifteen patients had complete tracheal rings, 6 of whom also had a left pulmonary artery sling. Fourteen patients underwent either tracheoplasty or resection and reanastomosis of the trachea, both facilitated by cardiopulmonary bypass. RESULTS: Six patients underwent resection and reanastomosis; 4 patients were extubated within 2 to 5 days without sequelae. There was 1 unrelated perioperative death. Two patients required reintubation. Eight patients required tracheoplasty due to severe tracheal stenosis and had variable postoperative courses. Seven of 14 patients required 0 to 1 postoperative bronchoscopies. Seven of 14 patients required 2 to 7 bronchoscopies for granulation tissue formation, cicatrix, graft collapse, and tracheitis. One patient required numerous procedures and revision tracheoplasty for cicatrix and stenosis. CONCLUSIONS: Correction of short-segment (<5 rings) tracheal stenosis by resection and reanastomosis of the trachea with the aid of cardiopulmonary bypass and early weaning of ventilatory support is recommended. Tracheoplasty using either the castellation technique or slide tracheoplasty is recommended in the treatment of infants with severe (long segment) tracheal stenosis.

Bronchoscopy

Infection control in the bronchoscopy suite. A review.

Bronchoscopy can occasionally transmit disease. Infection control in the bronchoscopy suite is especially important because of the risk of transmitting HIV or tuberculosis. Many case reports, patient series, and small studies have been published, but little comprehensive guidance is available for clinicians who wish to learn more about the problem and prevent it. We review the literature and describe three ways in which bronchoscopy can cause disease: by transmitting infections between patients, by transferring microorganisms within a patient, and by triggering coughing that can cause airborne infection of patients or health-care workers. Recommendations for infection control are listed; they include installing powerful air filters, using disposable bronchoscope suction valves, manually cleaning all equipment before disinfection, controlling patient coughing, and in some cases, giving patients prophylactic antibiotics.
