What Medical Professional Conducts Colonoscopy Tests?

by | Jun 13, 2024 | Medical

Colonoscopy is a vital diagnostic procedure used to examine the colon and rectum for signs of abnormalities such as polyps, inflammation, or cancer. The procedure itself is performed by a skilled medical professional. However, several specialists may be involved in different aspects of the process, from patient consultation to post-procedure care. Understanding the roles of these professionals is essential for patients undergoing colonoscopy tests, ensuring a smooth and effective experience from start to finish.


Gastroenterologists are physicians specializing in the diagnosis and treatment of digestive disorders, including conditions affecting the colon and rectum. They are the primary medical professionals who conduct colonoscopy tests, using a flexible tube with a camera attached (colonoscope) to examine the lining of the colon and rectum. Gastroenterologists undergo extensive training in endoscopic procedures, including colonoscopy, and have the expertise to interpret findings and recommend appropriate treatment or further evaluation based on the results.

Colorectal Surgeon

Colorectal surgeons are surgical specialists who focus on treating diseases and disorders of the colon, rectum, and anus. While they may not typically perform colonoscopy tests themselves, colorectal surgeons often collaborate with gastroenterologists, particularly in managing complex cases requiring surgical intervention. In cases where abnormalities such as polyps or tumors are detected during colonoscopy, colorectal surgeons may be involved in follow-up procedures such as polypectomy (removal of polyps) or surgical resection (removal of part of the colon).

Nurse Endoscopist

In some healthcare settings, specially trained nurses known as nurse endoscopists may perform colonoscopy tests under the supervision of a gastroenterologist or colorectal surgeon. Nurse endoscopists undergo rigorous training in endoscopic procedures and are proficient in performing colonoscopies with a high level of skill and precision. Their role may include preparing patients for the procedure, administering sedation, and assisting the gastroenterologist or surgeon during the examination.

Anesthesiologist or Nurse Anesthetist

Colonoscopy tests are typically performed under sedation to ensure patient comfort and relaxation during the procedure. Anesthesiologists or nurse anesthetists are responsible for administering and monitoring anesthesia during colonoscopy tests, ensuring that patients remain comfortable and pain-free throughout the examination. They play a crucial role in patient safety and may adjust the level of sedation as needed based on individual patient factors and the complexity of the procedure.


After a colonoscopy test, tissue samples (also known as biopsies) may be taken from any suspicious areas detected during the examination for further evaluation. Pathologists are medical professionals specializing in the study of disease processes and the interpretation of tissue samples. They analyze biopsy specimens obtained during colonoscopy tests to determine whether abnormalities such as precancerous polyps or cancerous lesions are present, providing valuable information for diagnosis and treatment planning.

Primary Care Physician

While primary care physicians do not typically perform colonoscopy tests themselves, they play a crucial role in coordinating patient care and recommending screening or diagnostic procedures based on individual risk factors and medical history. Primary care physicians may refer patients to gastroenterologists or colorectal surgeons for colonoscopy tests based on guidelines for colorectal cancer screening and recommendations tailored to each patient’s age, family history, and other risk factors.
