Olympus Bronchoscope: Uses and Differences from the Gastroscope
An Olympus bronchoscope is a flexible endoscope designed to view the inside of the trachea and bronchi and to perform diagnostic or therapeutic procedures without open surgery. If you run a pulmonology clinic and already work with gastrointestinal equipment, or are setting up the service from scratch, you may wonder whether what you already have is enough. It almost never is: the airway requires a different diameter, different maneuverability, and different reprocessing.
Imagine a clinic that already performs colonoscopies and gastroscopies with good results and decides to offer bronchoscopy because a pulmonologist has joined the team. The first instinct is to reuse towers, processors, and even the cleaning protocol. Some things can be shared, and others cannot. This guide helps you tell them apart.
What is a bronchoscope
A bronchoscope is a thin, flexible endoscope with a working channel that is inserted through the nose or mouth into the trachea and bronchi. It allows you to view the airway mucosa, take samples, and perform therapeutic maneuvers. In essence, it is the same concept as a gastroscope, adapted to a different area.
Like all endoscopes, it has a control section with angulation knobs, a cord that connects it to the processor, and an insertion section with an articulated distal tip. This is where the optics or image sensor, light, and working channel outlet are located. Forceps, brushes, needles, or catheters pass through this channel, and suction is also applied.
Olympus offers bronchoscopes in several generations and configurations, from high-definition video equipment to very thin models for small airways. Within Olympus endoscopy, they form their own family, with model codes that indicate the diameter and features. Later, you will see how to interpret them with clinical judgment.
Rigid and flexible: they are not the same
Rigid bronchoscopy also exists, which is performed with metal tubes under general anesthesia and is reserved mainly for complex therapeutic procedures, such as clearing an airway or placing certain stents. In a consultation room and in most clinics, when a bronchoscope is mentioned, the flexible one is meant, and that is what we are talking about here.
Respiratory procedures it is used for
Bronchoscopy is used to directly view the airway, obtain tissue or secretion samples, and treat some obstructions. It answers questions such as what is behind a lesion seen on a CT scan, where a persistent cough is coming from, or why part of a lung is collapsing.
If you are wondering what bronchoscopy is used for in daily practice, here are the most common uses:
- Diagnosis of lesions: inspection of masses or narrowings, with bronchial or transbronchial biopsy.
- Bronchoalveolar lavage: collection of samples to study infections or interstitial diseases, especially in immunosuppressed patients.
- Hemoptysis study: locating the source of bleeding.
- Removal of foreign bodies and mucus plugs: common in emergency rooms and in patients in intensive care.
- Assistance with difficult intubation: guidance for placing the tube under direct vision.
- Therapeutic procedures: dilations, stent placement, and other interventions depending on the equipment and the team's experience.
To study lymph nodes and lesions outside the bronchial wall, a variant with ultrasound at the tip is used. If you want to understand that technology, it is useful to read what an endobronchial ultrasound is, because the logic of combining optical imaging and ultrasound is the same, although the bronchial equipment has its own design.
Pediatric bronchoscopy
In children, the criteria change completely. The airway is small and the margin for error is minimal. Ultrafine equipment is needed, sometimes without a wide working channel, and an anesthesia team accustomed to pediatric patients. This affects the purchase: a single adult bronchoscope does not cover that service.
Differences from a gastrointestinal endoscope
A bronchoscope is thinner, has a narrower working channel, and is designed to move in an airway that should not be obstructed for long. The gastrointestinal endoscope is thicker and has more insufflation and lavage functions. The differences between a bronchoscope and a gastrointestinal endoscope are noticeable in diameter, the channel, air management, and reprocessing.
The following table summarizes the most important factors when deciding:
| Aspect | Bronchoscope | Gastrointestinal endoscope |
|---|---|---|
| Area | Trachea and bronchi | Esophagus, stomach, duodenum, colon |
| External diameter | Thinner, with ultrafine models | Thicker, more rigid |
| Working channel | Narrower, prioritizes suction and fine forceps | Wider, accommodates larger accessories |
| Air or CO2 insufflation | Not usually used | Essential part of the examination |
| Main risk if vision fails | Compromise of patient ventilation | Less urgent, but incomplete examination |
| Usual anesthesia | Topical anesthesia and sedation, depending on the case | Variable sedation depending on the procedure |
The difference that most surprises those coming from the gastrointestinal world is air. In the stomach or colon, you insufflate to separate the walls and see. In the bronchus, you do not insufflate: the patient breathes through the same airway through which the equipment passes, and every second of obstruction counts. Managing suction and lumen occupancy is part of the craft.
What can be shared and what cannot
Many clinics wonder if they can use the same processor and the same tower. In general, yes, as long as the processor is compatible with the bronchoscope series, but this must be confirmed model by model. What cannot be shared are the endoscopes or accessories: they are not interchanged between specialties for technical reasons and infection control.
Technical features to check
Before buying a bronchoscope, it is advisable to check four things: external diameter, working channel diameter, image type, and compatibility with your tower. The balance between them determines which patients and procedures you can treat with that equipment, and there is no model that works for everything.
This is what the pulmonology team should look at with the technical data sheet in hand:
- External and channel diameter: the larger the channel, the more therapeutic versatility and better suction, but less access to distal bronchi and small patients. Thin bronchoscopes favor access, thicker ones, therapeutics.
- Image quality: high definition helps recognize subtle changes in the mucosa. Ask if the model offers imaging with filters that highlight vessels, and if your processor supports them.
- Distal tip angulation: a good range of flexion up and down makes the difference when reaching the upper lobes.
- Compatibility: the processor, light source, connectors, and accessories must be from the same platform or certified as compatible.
- Condition and origin of the equipment: if you are considering used or refurbished equipment, ask for a repair history, leak test, and written warranty.
A common mistake is buying thinking only about the most complex case you might see once a year. If 90% of your procedures are washes and biopsies in adults, a standard channel equipment serves you better than an ultrafine one that is difficult to clean. Look at your real caseload before deciding.
Also do not forget the accessories: biopsy forceps, brushes, suction valves, and sample traps. Calculate their cost and replacement within the budget, not after.
Specific maintenance and reprocessing
The bronchoscope requires a leak test, immediate manual cleaning, high-level disinfection, and complete drying after each patient. Its channel is thin and long, so it is easier for organic matter to get trapped, and respiratory pathogens, such as mycobacteria, require special care.
The basic sequence is the same as any flexible endoscope: pre-cleaning in the room, leak test, manual cleaning with brushes of the appropriate size, disinfection or sterilization according to the protocol, rinsing, and drying with alcohol and air. What changes is the rigor. A narrow working channel does not forgive rushed brushing, and residual moisture favors bacterial growth during storage. The leak test deserves separate attention. A small perforation in the cover lets liquid into the interior and can render the equipment useless in a few cycles. In this guide on how to detect leaks in an endoscope, you find the step-by-step procedure, which also applies to bronchial equipment.
Good practices that prevent problems
- Use cleaning brushes of the exact diameter of the channel, and single-use when the manufacturer indicates.
- Record each reprocessing with date, equipment, patient, and person responsible, to be able to trace any incident.
- Store the bronchoscope hanging vertically and dry, not rolled up or inside its transport case.
- Follow the manufacturer's instructions and your institution's guidelines. As a general reference on the subject, you can consult the information from the World Health Organization on infection prevention and control.
Also plan who will do the reprocessing and with what training. An expensive bronchoscope poorly cleaned is a risk to the patient and an investment that deteriorates quickly.
When to consider a bronchoscope for the clinic
It is advisable to incorporate a bronchoscope when you have pulmonologists with training in the procedure, a sufficient volume of patients that you currently refer to another institution, and the real capacity to reprocess the equipment. If any of those three elements are missing, the equipment is underutilized or used without the necessary guarantees.
Ask yourself three questions before requesting a quote. First: how many procedures per month could you do at your own facility? Second: do you have a room, monitoring, suction, and staff to handle the airway if the patient has complications? Third: can your reprocessing area handle one more piece of equipment, with its traceability and its drying? If the answers are yes, the next step is to define the profile: adults or also pediatric, diagnostic or also therapeutic, with or without ultrasound. That definition determines the model, the accessories, and the tower.
To move forward, gather your caseload from the last few months, the data sheet of your current processor, and the current reprocessing protocol, and take them to a technical consultation. With those three documents, the person who advises you can propose a model tailored to your service and not a generic one. You can start by reviewing the Olympus endoscopy offer and comparing it with what you already have at home.
Frequently asked questions
What is an Olympus bronchoscope?
It is a flexible endoscope from the Olympus brand that is inserted through the nose or mouth to view and treat the trachea and bronchi. It has optics, light, angulation, and a working channel for biopsies, suction, and accessories. There are video, ultrafine, and ultrasound versions, depending on the clinical need.
What is bronchoscopy used for?
It is used to directly observe the airway, take biopsies, collect samples through bronchoalveolar lavage, locate the source of hemoptysis, remove foreign bodies or mucus plugs, and support therapeutic procedures such as dilations or stent placement, depending on the pulmonologist's indication.
What is the difference between a bronchoscope and a gastrointestinal endoscope?
The bronchoscope is thinner and has a narrower working channel, because it operates in an airway through which the patient must continue breathing. Air is not insufflated like in the digestive tract. In addition, reprocessing requires more care due to the length and diameter of the channel.
Can I use the same processor for a bronchoscope and gastroscope?
In many cases, yes, as long as the processor and light source are compatible with the bronchoscope series. Compatibility depends on the model, so you must confirm it with the manufacturer's data sheet or with your supplier before buying. Endoscopes and accessories are not shared between specialties.
How is a bronchoscope cleaned after each procedure?
Immediate pre-cleaning is done, leak test, manual cleaning with brushes of the appropriate diameter, high-level disinfection or sterilization according to the protocol, rinsing, and complete drying. Each cycle must be recorded. Always follow the manufacturer's instructions and your institution's standards.
What should a clinic check before buying a bronchoscope?
It should check the external and channel diameter, image quality, angulation, compatibility with its tower and processor, accessory cost, and reprocessing capacity. If the equipment is used, it is advisable to ask for a repair history, leak test, and written warranty, in addition to defining whether it will treat adults, children, or both.
