Questions regarding anal examinations?


I would like to ask the doctor about a situation where I have a feeling of fullness in my anus.
I went to a surgical clinic, and the doctor asked me to lie on my side for a digital examination.
I am unsure if it was done with a machine or a finger, but I felt like the doctor was probing inside.
I would like to know if this is considered an invasive examination.
Is there a need for antibiotic treatment? (I have a history of benign prostatic hyperplasia and acute prostatitis).
Thank you.

Both digital rectal examination and anoscopy are considered invasive procedures; however, the National Health Insurance Administration does not reimburse for digital rectal examinations.
Such examinations do not require the use of antibiotics unless the results indicate the presence of an infection.
Additionally, there is no correlation with a previous history of acute prostatitis.
Please do not use antibiotics indiscriminately to avoid the selection of antibiotic-resistant strains.

Invasive anal exams, such as digital rectal examinations (DRE), are common procedures performed by healthcare professionals to assess the condition of the rectum and surrounding structures. During this examination, the physician typically uses a gloved, lubricated finger to palpate the rectal area, which allows them to check for abnormalities such as masses, tenderness, or signs of inflammation. This procedure is considered invasive because it involves the insertion of a finger into the body, which can cause discomfort or anxiety for some patients.

Regarding your experience of feeling pressure or discomfort during the examination, it is not unusual for patients to feel a sensation of pressure or even mild discomfort, especially if there is an underlying condition such as prostatitis or hemorrhoids. The physician's goal during this examination is to gather information about your anal and rectal health, which can help in diagnosing any potential issues.

As for the need for antibiotics following an invasive anal exam, it generally depends on the specific circumstances surrounding your health. In most cases, a simple digital rectal exam does not necessitate the use of antibiotics, especially if there are no signs of infection or if the procedure is performed without complications. However, if you have a history of prostate issues, such as benign prostatic hyperplasia (BPH) or a previous episode of acute prostatitis, your physician may consider the potential risk of infection.

If you are experiencing symptoms such as fever, increased pain, swelling, or any discharge following the examination, it is crucial to contact your healthcare provider. These symptoms could indicate an infection, and in such cases, antibiotics may be warranted. Additionally, if the physician suspects that there may be an underlying infection or if they performed any procedures that could introduce bacteria into the body (such as biopsies or other interventions), they might prescribe antibiotics as a precautionary measure.

In summary, while a digital rectal examination is considered an invasive procedure, it typically does not require antibiotics unless there are specific indications of infection or if the physician deems it necessary based on your medical history and the findings during the exam. If you have concerns about your symptoms or the need for antibiotics, it is always best to discuss them directly with your healthcare provider, who can provide personalized advice based on your health status and any previous medical history.
