Safe Rectal Exam: 7 Steps for Painless Self-Examination at Home

Digital rectal examination (DRE) is a medical examination that helps doctors detect abnormalities in the anus, rectum, and prostate gland in men early. This method can help identify issues such as tumors, infections, injuries, or unusual signs that require further examination. Notably, digital rectal examination is not the same as rectal endoscopy: a direct manual examination is an initial assessment step, while endoscopy uses a scope to observe the inside of the rectum more clearly.

Many people only learn when a digital rectal exam is needed after experiencing anal bleeding, rectal pain, changes in bowel habits, or a feeling of abnormality during defecation. However, not all symptoms can be accurately assessed by a single method. In this article, Tiptory helps you understand what a digital rectal exam is for, whether it is painful, when a rectal endoscopy is needed, and in which cases you should see a doctor instead of self-examining at home.

Part 1: Proper Digital Rectal Examination Method

Step 1: Explain and Obtain Consent Before Examination

Clearly explain the purpose and procedure of the examination

• Before performing a digital rectal examination, medical staff need to briefly explain to the patient the purpose, basic steps, and sensations that may be experienced during the examination.

• It can be explained that the doctor will use a gloved finger and lubricant to examine the anal and rectal area, thereby assessing any potential abnormalities.

• The patient may feel slight pressure, fullness, or mild discomfort for a short period. Typically, a manual rectal examination only takes about 1-2 minutes, depending on the purpose and condition being evaluated.

• Prior explanation helps the patient understand what they will experience, reduces anxiety, and allows them to actively report if they feel pain or discomfort.

Ensure patient consent before proceeding

• Proceed with the anorectal examination only after the patient has been fully informed and has given consent.

• According to the medical facility's protocol, the patient may be asked to confirm or sign a procedure consent form before the examination.

• The patient has the right to ask questions, request further explanation, or refuse the examination if they do not feel ready.

• A digital rectal examination must be performed by appropriately trained medical personnel. Untrained individuals should not attempt to insert a finger or instrument into the rectum themselves as this can cause pain, bleeding, or damage to sensitive tissue.

Differentiating digital rectal examination from rectal endoscopy

• A manual rectal examination and rectal endoscopy are two different methods, although both are used to evaluate the rectal area.

• A digital rectal examination primarily helps the doctor quickly assess abnormalities that can be identified through direct palpation.

• Rectal endoscopy uses an endoscope to directly observe the inside of the rectum and may be indicated when it is necessary to evaluate lesions that cannot be fully determined by manual examination.

• The choice of method depends on the symptoms, medical history, and the doctor's professional assessment.

Step 2: Hand Hygiene and Gloving Before Examination

Proper hand washing and disinfection

• Before performing a digital rectal examination, medical staff should wash their hands thoroughly with soap and water to minimize the risk of introducing bacteria, viruses, or parasites into the anal-rectal area.

• After washing, hands should be completely dried. In appropriate cases, an alcohol-based hand sanitizer may also be used according to the medical facility's infection control protocol.

• This is a basic but very important hygiene step, as the anal and rectal areas have a rich microbiota, and the mucous membranes there are quite sensitive.

Use new examination gloves

• After hand hygiene, medical staff should wear a pair of clean, new examination gloves that comply with infection control regulations.

• Gloves create an additional protective barrier between the examiner's hand and the anal-rectal area, while also limiting cross-contamination.

• If the patient or medical staff has a history of latex allergy, suitable latex-free gloves should be chosen.

Examination by trained medical staff

• A manual rectal examination is a medical procedure that must be performed by a qualified and trained professional; it should not be attempted at home.

• Depending on the symptoms and evaluation purpose, the patient may be examined by a general practitioner, gynecologist, proctologist, or other medical personnel trained to perform this procedure.

• Proctology specializes in diseases related to the anus, rectum, and colon, and therefore can manage cases requiring more in-depth evaluation.

Do not confuse digital rectal examination with rectal endoscopy

• A digital rectal examination is an initial physical examination in many cases, helping the doctor assess some abnormalities in the anal and rectal area.

• Rectal endoscopy is a method that uses an endoscope to directly observe the inside of the rectum and is performed when appropriate.

• If anal pain, bleeding during bowel movements, an abnormal mass, or changes in bowel habits occur, the patient should consult a doctor to determine if a digital rectal examination, rectal endoscopy, or other tests are needed.

Step 3: Make the Patient Comfortable Before the Examination

Reassurance and explanation before starting

• A digital rectal examination can make many people feel embarrassed or anxious. Medical staff should communicate calmly and respectfully, explaining each step clearly before proceeding.

• The patient needs to know the examination position, the scope of the examination, and the sensations that may be experienced. If they feel pain or excessive discomfort, the patient should inform the doctor immediately so that the procedure can be adjusted or stopped.

• In cases where the patient feels uncomfortable, they can discuss the gender of the examiner or request the presence of another medical staff member in the room if the medical facility supports it.

Positioning the patient correctly on their side

• A common position used for a manual rectal examination is lying on the left side, with both knees moderately bent towards the chest.

• This position helps the patient relax more and facilitates the doctor's access to the anal-rectal area.

• Depending on the clinical situation, the doctor may choose a different position. Not all anorectal examinations require the patient to be in a side-lying position.

Ensuring privacy and safety

• After the patient changes or lowers their clothing appropriate to the scope of the examination, a gown, sheet, or drape should be used to cover areas not being examined.

• Covering not only helps keep the patient warm but also reduces feelings of vulnerability and loss of privacy during the digital rectal examination.

• A clean disposable pad can be placed under the buttocks to protect the examination table and maintain hygiene.

Respecting individual comfort

• The level of anxiety and comfort during a digital rectal examination varies from person to person. The doctor should discuss the position beforehand and answer any concerns related to the procedure.

• The patient can ask about the presence of a second medical staff member in the room or a accompanying support person, depending on the medical facility's policy.

• The most important thing is that the patient is respected, their information is kept confidential, and their consent is maintained throughout the examination.

Note on rectal endoscopy

• The position for rectal endoscopy may differ from a manual examination and will be guided by medical staff based on the type of endoscopy, equipment used, and examination purpose.

• Patients should not choose or perform positions, insert fingers, or any instruments into the rectum at home. This procedure must be performed by a qualified medical professional.

Step 4: Use Lubricant to Reduce Discomfort

Using appropriate lubricant

• Before a manual rectal examination, medical staff typically use an appropriate medical lubricant to reduce friction and minimize discomfort during the examination.

• The lubricant should be used according to the medical facility's protocol. Do not arbitrarily use creams, oils, or household products as substitutes, as they can irritate the mucous membrane or affect medical instruments.

• The patient may feel slight pressure or fullness during the examination. Relaxing the anal muscles can make the examination more comfortable.

Communicate if the patient is anxious or overly sensitive

• If the patient is too tense, in pain, or has severe anal sphincter spasm, the doctor may re-evaluate the approach rather than attempting to continue the procedure when there is a risk of causing pain or injury.

• In some special cases, the doctor may consider pain relief or local anesthesia if absolutely necessary. This must be based on the specific situation and performed by medical personnel.

• The patient should report immediately if they experience severe pain, unusual pain, or bleeding during the anorectal examination.

Do not heat lubricant at home

• The temperature of the lubricant used must be safe and conform to medical procedures. Do not arbitrarily heat products in a microwave or other heat sources without manufacturer instructions and guidance from medical staff.

• When performing a digital rectal examination, the doctor or medical facility will select the appropriate product and method of use to minimize irritation and ensure safety.

Differentiating from rectal endoscopy

• Rectal endoscopy may also require lubricant to help insert the instrument and reduce friction, but preparation depends on the type of equipment and the medical facility's procedure.

• Do not attempt to insert fingers or any instruments into the anus yourself to replace a digital rectal examination or rectal endoscopy.

Step 5: Gently Insert Finger into the Rectum

Examine the anal area before palpation

• Before performing a manual rectal examination, the doctor needs to visually inspect the anal area for any visible abnormalities.

• Signs to look for include hemorrhoids, anal fissures, warts, rashes, swelling, or skin and tissue lesions around the anus.

• If significant abnormalities are found, the doctor will consider an appropriate approach rather than attempting to continue the procedure if there is a risk of causing pain or injury.

Perform the examination gently

• A digital rectal examination must be performed by trained medical personnel, with appropriate technique and patient consent.

• The patient is instructed to relax and breathe evenly to reduce tension, especially if the anal sphincter is tight.

• The doctor uses examination gloves and an appropriate medical lubricant, then proceeds with the examination slowly, avoiding forceful movements or trying to proceed if the patient feels pain.

• If severe pain, bleeding, or unusual discomfort occurs, the patient should immediately inform the doctor for evaluation and adjustment of the examination.

Assess anal sphincter tone

• In some cases, the doctor may assess anal sphincter tone to check the muscle's ability to contract and relax.

• The patient may be gently instructed to contract their anal muscles or strain as requested by the doctor. This information helps evaluate the function of the anal-rectal muscles.

• The results of the anorectal examination should be combined with symptoms, medical history, and other clinical findings, rather than using a single sign to make a diagnosis.

Do not perform at home

• A digital rectal examination is not a procedure that should be performed by oneself or by an untrained person.

• If there is anal pain, rectal bleeding, an abnormal mass, changes in bowel habits, or persistent symptoms, a medical facility should be consulted for evaluation.

• When direct visualization inside the rectum is needed, the doctor may consider rectal endoscopy or other appropriate diagnostic methods based on the specific condition.

Step 6: Assess for Abnormalities in the Rectum

Check for abnormal signs

• During a manual rectal examination, the doctor can assess the rectal wall to detect abnormal changes such as a hard mass, bulging area, abnormally soft spot, pain, or signs of injury.

• This assessment must be performed gently, systematically, and only by trained medical personnel. Self-examination inside the rectum at home is not recommended.

• The examination results should not be used in isolation to diagnose cancer, infection, or a specific medical condition. If an abnormality is detected, the doctor may order additional tests or a rectal endoscopy for further evaluation.

Prostate examination in men

• In men, a digital rectal examination can be used by the doctor to assess the prostate gland through the rectal wall.

• The doctor can note characteristics such as size, firmness, surface, symmetry, and degree of pain when touching the prostate.

• A normal prostate typically has a relatively smooth surface and does not cause pain during examination. However, relying solely on a digital rectal prostate examination cannot confirm whether a person has prostate cancer.

• If pain occurs during the examination, an enlarged prostate, or an abnormally hard area, the doctor will combine this with symptoms, medical history, and necessary tests to find the cause.

Feeling of needing to urinate may occur

• Some men may feel the urge to urinate or need to urinate when the prostate is stimulated during the examination. This can be a normal reaction due to the close proximity of the rectum, prostate, and urinary tract.

• However, if pain or discomfort persists after the examination, the patient should inform the medical staff for evaluation.

When is further examination needed?

• A digital rectal examination is only one part of the anorectal health assessment process and does not fully replace other diagnostic methods.

• If there is rectal bleeding, persistent anal pain, changes in bowel habits, unexplained weight loss, or an abnormal mass, the doctor may consider more specialized tests.

• Rectal endoscopy may be indicated in cases where direct visualization of the rectal mucosa is needed or to clarify the cause of certain symptoms.

Step 7: Concluding the examination and post-procedure hygiene

Withdrawal of finger and post-examination check

• After completing the digital rectal exam, the doctor should withdraw their finger slowly and gently to minimize discomfort for the patient.

• The examination glove can be inspected for the presence of blood, mucus, or abnormal discharge. These signs should be evaluated along with symptoms and examination results, without self-concluding the cause.

• If blood is found, the doctor may consider causes such as hemorrhoids, anal fissures, or other anorectal issues depending on the specific situation.

Perianal hygiene and proper glove removal

• After the examination, any remaining lubricant around the anus should be appropriately cleaned, and used gloves must be removed and disposed of according to infection control regulations.

• Medical personnel should wash their hands after removing gloves to reduce the risk of cross-contamination.

• Patients should be provided with privacy to clean the perianal area themselves and get dressed.

Monitoring the patient's condition

• After a rectal examination, the doctor should ask the patient about their current feelings, especially if they were anxious or uncomfortable beforehand.

• Some people may feel slightly dizzy when changing from a lying to a standing position. Therefore, it is advisable to stand up slowly and inform medical staff if dizziness, lightheadedness, or a feeling of fainting occurs.

• If there is heavy bleeding, severe pain, or persistent abnormal symptoms, the patient should seek medical evaluation instead of self-monitoring at home.

Evaluating results and deciding next steps

• A rectal exam provides initial information but does not always identify the cause of symptoms.

• If suspicious signs are found or results are not clear enough, the doctor may order additional tests, imaging, or a rectal endoscopy, depending on the case.

• Patients should discuss the results of the rectal exam directly with their doctor, especially if there is blood in the stool, rectal bleeding, rectal pain, or changes in bowel habits.

Part 2: What is a rectal exam and when is it needed?

Note 1: Seek examination if blood is in stool

Seek examination if blood in stool is detected

• If you see blood in your stool, blood in the toilet, or blood when wiping after a bowel movement, you should seek examination instead of self-diagnosing the cause.

• A rectal exam can help the doctor initially assess the anus and rectum, especially when the patient has bleeding symptoms.

• The color and amount of blood can provide additional information, but not enough to accurately determine the location or cause of the bleeding.

Common causes

• Anal bleeding can be related to relatively common causes such as:

  • Hemorrhoids, especially when blood appears after defecation.

  • Anal fissures, often accompanied by pain or burning during bowel movements.

  • Injury or irritation of the anal area due to straining or excessive wiping.

• However, rectal bleeding can also be associated with more serious conditions, so it should not be assumed that every case is hemorrhoids.

When might endoscopy be needed?

• If the doctor suspects the bleeding source is deeper in the colon or needs to find a cause that a rectal exam has not identified, the patient may be referred for additional tests.

• Depending on symptoms and clinical assessment, the doctor may consider a rectal endoscopy, colonoscopy, or other diagnostic methods.

• A normal rectal exam does not mean that gastrointestinal conditions are completely ruled out. Some lesions are beyond the scope of observation or cannot be detected by manual examination.

Examination is usually quick

• A rectal examination is usually performed in a short time, and in most cases, anesthesia is not required.

• Patients may feel slight pressure or mild discomfort during the examination. If the pain is severe, it should be reported to medical staff immediately.

• After the examination, the doctor will decide whether further monitoring, additional tests, or a rectal endoscopy is needed based on symptoms and examination results.

Do not delay when there are abnormal signs

• Seek early examination if bleeding recurs or is accompanied by abdominal pain, changes in bowel habits, unexplained weight loss, fatigue, or unusual changes in stool.

• If there is heavy bleeding, continuous bleeding, tarry black stools, or the onset of dizziness, weakness, or fainting, immediate medical attention is required.

Note 2: Men with difficult urination should seek examination

Seek examination for abnormal urination symptoms

• Men experiencing difficulty urinating, difficulty initiating urination, dribbling, weak stream, or a feeling of incomplete emptying should seek examination to find the cause.

• In some cases, the doctor may perform a rectal exam to assess the prostate gland, as it is located directly in front of the rectum and can be examined through the rectal wall.

• Not all cases of difficult urination are due to the prostate. The doctor will rely on age, symptoms, medical history, and examination results to determine the appropriate course of testing.

Prostate assessment via rectal exam

• A digital rectal exam of the prostate can help the doctor relatively assess the size, surface, consistency, and tenderness of the prostate gland.

• The prostate gland can undergo benign enlargement with age. This condition often causes lower urinary tract symptoms such as difficult urination or a weak stream but does not necessarily mean cancer.

• If the doctor notices abnormal characteristics of the prostate, the patient may be referred for additional tests to find the cause.

PSA testing may be needed

• Blood test for PSA (prostate-specific antigen) can be used in assessing prostate cancer risk in suitable individuals.

• An elevated PSA does not definitively mean prostate cancer, as this indicator can also be elevated due to benign prostatic hyperplasia, inflammation, or other causes.

• Therefore, PSA results need to be interpreted by a doctor within the overall context, rather than concluding based on a single number.

When is more specialized investigation needed?

• If a rectal exam or initial tests show suspicious signs, the doctor may request further imaging or specialized tests.

• In some cases, transrectal ultrasound may be indicated to assess the prostate and assist in performing a biopsy if needed.

• Rectal endoscopy is not a routinely used test for diagnosing prostate conditions. This method primarily assesses the inside of the rectum and is indicated based on symptoms or suspected rectal pathology.

Do not wait until symptoms are severe

• If difficult urination in men is prolonged, recurrent, or becoming more pronounced, an early evaluation is recommended.

• Especially if there is inability to urinate, severe lower abdominal pain, or other abnormal symptoms, timely medical attention is required.

Note 3: When should a regular rectal exam be performed?

A single examination schedule should not be applied to all

• A rectal exam can be part of a health check-up for individuals with symptoms or those who need assessment. However, not everyone needs an annual regular rectal exam based solely on age.

• Current colorectal cancer screening guidelines depend on age, individual risk, family history, and the chosen screening method. Therefore, it is advisable to discuss with a doctor to determine the appropriate timing and tests.

• Individuals with a family history of colorectal cancer, intestinal diseases, or other risk factors may need earlier assessment or a personalized schedule.

Men need to pay attention to prostate health

• In men, doctors may consider a digital rectal exam of the prostate when evaluating urinary symptoms or the risk of prostate conditions.

• A rectal exam is not the only method for screening or diagnosing prostate cancer. Depending on the case, the doctor may combine patient history, physical examination, and PSA testing.

• The examination position may vary depending on the purpose and procedures of the medical facility; the patient will be guided to the appropriate position.

Women may have combined exams when necessary

• In women, a rectal examination is sometimes performed along with a gynecological exam when the doctor needs to assess the pelvic area or specific symptoms.

• However, a rectal exam is not a routine screening test for uterine or ovarian cancer. The examination should be based on symptoms and clinical indications.

Seek examination when abnormal symptoms appear

• In addition to rectal bleeding or abnormal urination, doctors may indicate a rectal exam when the patient experiences:

  • Changes in bowel habits that are prolonged or abnormal.

  • Unexplained pelvic or abdominal pain.

  • Anal pain or a feeling of an abnormal mass.

  • Bleeding or abnormal discharge from the urinary tract.

• If direct observation of the mucosa is needed, the doctor may consider a rectal endoscopy or colonoscopy depending on the suspected location and diagnostic objective.

Proactive screening based on individual risk

• Do not wait until symptoms appear to consider colorectal cancer screening.

• For individuals in the screening age group or at high risk, the doctor may choose stool tests, colonoscopy, or other suitable methods.

• The most effective approach is to view rectal exams, rectal endoscopies, and screening tests as different tools within the same health "filter," rather than believing one method can detect all conditions.

What preparations are needed before a rectal exam?

Usually no special preparation needed

• For a digital rectal exam, patients generally do not need to fast or undergo complex bowel preparation procedures like some endoscopic procedures.

• After a rectal exam, in most cases, patients can resume normal daily activities unless otherwise instructed by the doctor.

• If you feel the urge to defecate, having a bowel movement before the exam can help you feel more comfortable.

May feel the urge to defecate during the exam

• Slight stimulation of the anorectal area during a rectal examination can create a temporary sensation of needing to pass stool or tenesmus.

• This is a possible reaction and not necessarily a sign of abnormality.

• If you feel the need to use the restroom during the exam, inform the medical staff for guidance.

In some cases, stool samples may be collected

• In some situations, the doctor may collect stool samples during the examination to perform appropriate tests.

• However, a rectal exam does not replace colorectal cancer screening tests. The choice of test depends on the individual's age, symptoms, and risk level.

Do not self-prepare with enemas unless instructed

• Patients should not self-administer enemas or use laxatives before a rectal exam unless instructed by the doctor.

• It is important to distinguish between a rectal exam and a rectal endoscopy: endoscopy may have specific bowel preparation requirements depending on the type of procedure and the medical facility's instructions.

• If you are scheduled for a rectal endoscopy, follow the preparation instructions provided by your doctor or the endoscopy facility.
