An endoscopy technician (endo tech) assists gastroenterologists before, during, and after procedures that use a flexible camera to examine the digestive tract. The role sits at the intersection of patient care, technical equipment handling, and infection control. On a typical day, an endo tech prepares procedure rooms, hands instruments to the physician during colonoscopies and upper endoscopies, monitors patients, and then meticulously cleans every scope so it’s safe for the next person.
What Happens During a Procedure
Endo techs work alongside the physician for every case on the schedule, which usually means colonoscopies, upper endoscopies (EGD), and sometimes more complex procedures like ERCP, where a scope threads from the mouth down into the bile and pancreatic ducts. Before the patient enters the room, the tech sets up the video monitors, tests the light source, connects the scope, and lays out any accessories the physician might need: biopsy forceps, snares for polyp removal, or injection needles.
Once the procedure starts, the tech manages the scope’s video system, adjusts suction and air flow, and passes instruments through the scope’s working channel on the physician’s command. During a polypectomy, for instance, the tech feeds a wire snare through the scope so the doctor can lasso and remove a polyp. In ERCP cases, contrast dye is injected through the scope to make the bile ducts visible on X-ray, and the tech coordinates that equipment as well. Speed and anticipation matter here: experienced techs often have the next tool ready before the physician asks for it, which keeps procedure times short and reduces patient discomfort.
Scope Reprocessing and Infection Control
Cleaning endoscopes is one of the most critical parts of the job. Flexible scopes have narrow internal channels that can harbor bacteria if reprocessing isn’t done correctly. The CDC outlines seven essential steps that endo techs follow after every single procedure:
- Pre-cleaning happens immediately after the scope leaves the patient. The tech flushes channels and wipes down the exterior to prevent biofilm from forming.
- Leak testing checks for tiny holes in the scope’s outer sheath or internal tubing that could let fluid seep in and compromise disinfection.
- Manual cleaning is considered the most critical step. The tech brushes every channel and port by hand, then flushes them with enzymatic detergent. Skipping this step or rushing it can make later disinfection ineffective, because organic material shields bacteria from chemical agents.
- Visual inspection under magnification confirms the scope is free of visible soil and physical defects.
- High-level disinfection or sterilization uses chemical agents or an automated reprocessing machine to kill remaining microorganisms.
- Drying and storage in a vertical hanging cabinet prevents recontamination and moisture buildup.
Beyond scope cleaning, endo techs wear fresh personal protective equipment for every patient, discard it before leaving the procedure area, and verify that all surfaces in the room have been properly disinfected between cases. Before the first case of the day, staff confirm that every procedural and recovery area has been cleaned from the previous session.
Patient Preparation and Safety Checks
Endo techs often help prepare patients in the pre-procedure area: confirming identity, verifying which procedure is scheduled, and making sure consent forms are complete. This “time-out” verification, where the patient, staff, and physician all confirm the correct patient and correct procedure, is a standard safety step the tech participates in before every case. Depending on the facility, the tech may also help position the patient on the procedure table, attach monitoring equipment, and assist with sedation setup.
Where Endo Techs Work
Most endo techs work in hospital-based GI endoscopy units or outpatient ambulatory surgery centers. Outpatient centers tend to run a high volume of screening colonoscopies, while hospital units see a broader mix of cases, including emergency procedures for GI bleeding. Some facilities hire per diem techs who fill shifts as needed rather than working a fixed schedule. Shifts generally follow daytime hours since most endoscopy suites operate on a scheduled caseload, though hospital-based techs may occasionally be called in for urgent after-hours procedures.
Physical Demands of the Job
This is not a desk job. According to O*NET data from the U.S. Department of Labor, 72% of endo techs report standing continually or almost continually during their shifts. The work involves lifting, bending, and handling heavy equipment. Eighty-four percent say they’re exposed to disease or infectious material every day, and 96% wear protective gear (gloves, gowns, eye protection) daily. Exposure to chemical disinfectants used in scope reprocessing is another routine part of the environment, with 60% reporting daily contact with contaminants.
Education and Certification
Most endo tech positions require a high school diploma or equivalent, and many employers prefer candidates with prior experience in sterile processing, surgical technology, or patient care. On-the-job training is common, but formal credentials can give candidates an edge and are increasingly expected at larger hospitals.
The Society of Gastroenterology Nurses and Associates (SGNA) offers an Associates Program, an eight-module online course covering GI anatomy, endoscopic equipment, infection prevention, patient care, risk management, and emergency preparedness. Completing the course and passing the exam earns a GI Technical Specialist (GTS) designation. The Healthcare Sterile Processing Association offers a separate Certified Endoscope Reprocessor (CER) credential focused specifically on scope cleaning and disinfection. The CER is a standalone certification, meaning you don’t need any prior credentials to sit for the exam.
Salary and Job Outlook
Endo techs fall under the broader “healthcare support workers” category in federal wage data. The median annual salary for this group is roughly $46,050, or about $22 per hour, based on May 2023 estimates. Actual pay varies with location, facility type, and experience. Techs working in major metro areas or hospital systems with high procedure volumes tend to earn toward the upper end of the range.
The Bureau of Labor Statistics projects 4% employment growth for endoscopy technicians between 2024 and 2034. That’s roughly in line with the average for all occupations. Demand is driven largely by an aging population that needs more colorectal cancer screenings and diagnostic procedures, plus expanding use of outpatient endoscopy centers that need dedicated technical staff.
