Endoscopy means looking inside and typically refers to looking inside the body for medical reasons using an endoscope, an instrument used to examine the interior of a hollow organ or cavity of the body. Unlike most other medical imaging devices, endoscopes are inserted directly into the organ.

What kinds are there 

Health care providers can use endoscopy to review any of the following body parts:

  • the gastrointestinal tract (GI tract): oesophagus, stomach and duodenum (esophagogastroduodenoscopy)

  • small intestine (enteroscopy)

  • large intestine/colon (colonoscopy, sigmoidoscopy)

  • magnification endoscopy

  • bile duct: endoscopic retrograde cholangiopancreatography (ERCP), duodenoscope-assisted cholangiopancreatoscopy, intraoperative cholangioscopy

  • rectum (rectoscopy) and anus (anoscopy), both also referred to as (proctoscopy)

  • the respiratory tract

  • the nose (rhinoscopy)

  • the lower respiratory tract (bronchoscopy)

  • the ear (otoscope)

  • the urinary tract (cystoscopy)

  • the female reproductive system (gynoscopy)

  • the cervix (colposcopy)

  • the uterus (hysteroscopy)

  • the fallopian tubes (falloposcopy)

Normally closed body cavities (through a small incision):

  • the abdominal or pelvic cavity (laparoscopy)

  • the interior of a joint (arthroscopy)

  • organs of the chest (thoracoscopy and mediastinoscopy)

Endoscopy is used for many procedures:

  • during pregnancy

    • the amnion (amnioscopy)

    • the fetus (fetoscopy)

  • plastic surgery

  • panendoscopy (or triple endoscopy): combines laryngoscopy, esophagoscopy, and bronchoscopy

  • orthopedic surgery

    • Hand surgery, such as endoscopic carpal tunnel release

    • knee surgery, such as anterior cruciate ligament reconstruction

    • epidural space (Epiduroscopy)

    • bursae (Bursectomy)

  • endodontic surgery

    • maxillary sinus surgery

    • apicoectomy

  • endoscopic endonasal surgery

  • endoscopic spinal surgery


Why it's needed

For examination/surgery of the gastrointestinal tract, the respiratory tract, the ear, the urinary tract, the female reproductive system, normally closed body cavities (through a small incision), during pregnancy, or orthopedic surgery.


The indications of performing an endoscopy vary depending on the area of focus.

Medela products

We recommend the Basic suction pump. If large volumes of fluid are suctioned, the Dominant Flex at a setting of 60 l/min (other flow rates can also be chosen) may be a good alternative. Both pumps are available as rack versions for easy placement in the endoscopy tower and are capable of reaching the vacuum levels necessary for the procedures. However, these are only recommendations, the individual setting is the responsibility of the medical practitioner.


Benefits of Dominant Flex suction pump for endoscopy:
Powerful but silent
  • By reducing the noise level in the endoscopy suite, less mistakes are made. The Dominant Flex is as quiet as a summer night,  but still delivers powerful suction.
  • State-of-the-art technology creates vacuum immediately.
  • You have a choice. Choose 60 l/min for fast removal of rinsing fluids, 50 l/min is the default mode for most applications, and if you need less noise, choose 40 l/min.
User-centric design for ease of use
  • Designed for optimal placement in standard endoscopy towers.
  • Collection system and accessories have intuitive plug-in connections to accelerate set-up time and facilitate handling.
Swiss engineering to prevent infections
  • Touch-activated buttons and the housing with no gaps or grooves facilitate cleaning and minimize risk of infections.
  • Medela's DCS disposable liners all have a bacteria/overflow protection filter integrated.
  • As additional safety measure, the mechanical overflow set (Safety Set) protects the pump.
Designed to last a lifetime
  • With 50 years of experience, Medela has created robust pumps with a 5-year warranty on the complete pump.

Suction levels

The suction levels vary depending on the type of endsocopy performed. All necessary vacuum levels can be precisely set and maintained with the Medela Dominant Flex or Basic suction pumps.
