Hysteroscopy vs endometrial biopsy: what each workflow requires of the clinic

Blind aspiration sampling: a light-footprint set-up

A blind endometrial sample is taken with a thin aspiration catheter, commonly called a pipelle-type device, passed through the cervix without direct vision. The equipment footprint is small: an examination couch with leg supports, a light, a vaginal speculum, a tenaculum if used, a uterine sound, the single-use sampling device, specimen containers with fixative and labels, and a waste route.

Most of these are standard gynecology instruments. In the REDA range, gynaecology instruments include Cusco, Pederson, Collin and Sims specula, uterine sounds, tenaculum and biopsy punch forceps, and aspiration curettes. Consumables, such as sampling catheters, are normally procured as single-use items and managed in the supplies budget.

Specimen handling deserves a written routine. Label containers at the point of collection, agree the fixative and the transport route to the laboratory, and keep a log so that every sample can be traced from the room to the report.

Hysteroscopic guided biopsy: an imaging chain in the room

In hysteroscopic guided biopsy the telescope shows the cavity and the operator takes a targeted sample through a working channel or with instruments passed alongside. The room therefore needs an imaging chain: telescope, sheath, light, camera and monitor, plus a way to distend the cavity.

Systems such as the ENDOCAM Logic HD combine an LED light source with the camera and monitors; per its data the camera automatically controls the light source, application profiles are stored, and full HD video can be recorded to USB for the patient file. See our guide to the hysteroscopy fluid management pump for the distension side.

• Telescope and sheath sized to the clinic's chosen diagnostic workflow.
• Light source, camera head, controller and monitor on a mobile tower.
• Distension medium delivery and fluid-collection arrangements.
• Biopsy forceps or other semi-rigid instruments compatible with the sheath.
• Image and video recording that fits the clinic's records policy.

Office hysteroscopy with endometrial biopsy: combining both

Many outpatient services use hysteroscopy first and add sampling in the same visit. For the clinic this means one room with the tower and the instruments for both, and a clear rule for who prepares what. A single procedure trolley with a sealed tray of speculum, tenaculum and sound, plus the telescope set, keeps turnover predictable.

Our office hysteroscopy equipment guide covers the room layout, power and storage in more detail. Whether a particular patient is suited to one approach or another remains the decision of the treating physician.

Reprocessing and cost drivers

Blind sampling leans on disposables, so recurring cost sits in the consumable line and the main reprocessing burden is the speculum and instrument set. Hysteroscopy shifts cost toward capital equipment and endoscope reprocessing: scopes and sheaths need manufacturer-validated cleaning and sterilization or disinfection, and a spare telescope helps protect the list.

A sound way to compare is to model both services over the expected case volume, adding capital, consumables, reprocessing labour, repairs and staff training, rather than using a single price. We discuss that method in the article on total cost of ownership.

Plan spares as well. A second telescope or a loan arrangement, spare light cables and a reserve of camera drapes are inexpensive compared with a cancelled list, and they should be written into the supply contract.

Questions to ask suppliers

Ask for registration status, the sheath and telescope sizes available, instrument compatibility, training, service coverage and loan units during repairs. Beckfinity can prepare a proposal combining Richard Wolf imaging with REDA instruments for your clinic; request it through our contact page.
