Rectal examination?


Hello, doctor.
I have been experiencing rectal bleeding when using the restroom and would like to seek outpatient treatment.
However, during previous visits to the clinic, I noticed metal examination instruments in a bucket.
Can you please clarify whether these instruments are reused or if they are properly sterilized before being inserted into the rectum for examination? I am quite concerned about the risk of infection, which is why I have been hesitant to seek an examination.
I hope you can help alleviate my concerns.

Hello: In response to your question, the iron instrument you are referring to is likely an anoscope.
This examination tool is cleaned and disinfected after use and undergoes high-pressure sterilization before being reused, ensuring complete safety.
There are also disposable anoscopes available; however, they are not covered by health insurance and are relatively expensive, with few hospitals in the country adopting them.

When it comes to medical procedures, especially those involving sensitive areas such as rectal examinations, the concern for infection is entirely valid. The use of rectal exam instruments raises important questions about sterilization practices and the potential risk of infection.
Firstly, it is essential to understand that medical facilities, particularly those that are accredited and follow established health regulations, are required to adhere to strict sterilization protocols. Instruments used for rectal examinations, such as rectal thermometers, speculums, and other tools, should be either single-use or properly sterilized between patients. This is crucial to prevent the transmission of infections, including bacterial and viral pathogens.

In most healthcare settings, reusable instruments undergo a rigorous cleaning and sterilization process. This typically involves several steps:
1. Cleaning: Instruments are first cleaned to remove any organic material, such as blood or mucus. This is often done using detergents and brushes.

2. Disinfection: After cleaning, instruments are subjected to disinfection processes, which may include soaking in chemical disinfectants.

3. Sterilization: Finally, instruments are sterilized using methods such as autoclaving (steam sterilization), which effectively kills all forms of microbial life, including spores.

Regarding your concern about the metal instruments you observed in a water bucket, it is important to note that proper medical facilities should not store used instruments in such a manner. Instruments should be immediately cleaned and sterilized after use to minimize any risk of cross-contamination. If you have doubts about the sterilization practices at a particular clinic, it is advisable to ask the healthcare provider directly about their protocols. A reputable clinic will be transparent about their sterilization methods and should be able to reassure you about the safety of their practices.

As for the risk of infection from rectal examinations, if proper sterilization protocols are followed, the risk is significantly minimized. However, if instruments are reused without adequate cleaning and sterilization, there is a potential risk of transmitting infections, including but not limited to bacterial infections, hepatitis, or other bloodborne pathogens.

If you are experiencing rectal bleeding, it is crucial to seek medical attention. Delaying necessary examinations due to fear of infection can lead to worsening conditions. You can express your concerns to your healthcare provider, who should be willing to address them and ensure that all instruments used during your examination are properly sterilized.

In summary, while the risk of infection from rectal exam instruments can be a concern, adherence to proper sterilization protocols in accredited medical facilities significantly reduces this risk. If you have any doubts about the practices at a specific clinic, do not hesitate to ask questions or seek care at a facility that prioritizes patient safety and infection control. Your health is paramount, and addressing any medical issues promptly is essential.
