What is Endoscopy ?

What is Endoscopy?

Endoscopy is a modern medical diagnostic and treatment method used to examine the internal organs and tissues of the body in detail. In this procedure, an endoscope, a thin, flexible tube with a small camera at its tip, is used. The endoscope is inserted into the body through the mouth, nose, anus, or a small surgical incision if necessary, and guided to the targeted area. This allows doctors to obtain a clear image of the area and, if necessary, take biopsies or perform minor surgical procedures.

Endoscopy plays a crucial role in the early diagnosis of diseases and the creation of an accurate treatment plan. While frequently used in the diagnosis of digestive system diseases such as those of the esophagus, stomach, and intestines, this method is also preferred for evaluating different parts of the body, such as the respiratory tract, bladder, uterus, and joints. Thanks to its detailed visualization capabilities, endoscopy has become an indispensable technique in many areas of medicine.

What are the Types of Endoscopy?

Different types of endoscopy are important medical methods that allow for the visualization of the body’s internal structures and the diagnosis and treatment of various diseases. Developed depending on the area of ​​the body to be examined and medical needs, these methods offer doctors the opportunity to manage a wide range of diseases with minimally invasive procedures.

Here are the main types of endoscopy and their areas of use:

Gastroscopy (Upper Digestive System Endoscopy)

Gastroscopy is a method used to examine the esophagus, stomach, and duodenum. A gastroscope, a flexible tube, is inserted through the mouth to provide a detailed view of the inner surface of these structures. It is used to detect diseases such as reflux, gastritis, peptic ulcers, and Helicobacter pylori. It also allows for therapeutic procedures such as stopping digestive system bleeding, removing polyps, or clearing foreign bodies. Biopsies can be taken if necessary, and the procedure is usually performed under mild sedation.

Colonoscopy (Lower Digestive System Endoscopy)

A colonoscopy is a procedure performed to examine the large intestine and the last part of the small intestine. It is generally recommended for individuals over 50 years of age or those with a family history of risk factors for colon cancer screening. Detection and removal of polyps, examination of inflammatory bowel diseases, and investigation of causes of bleeding are the main uses of colonoscopy. Bowel cleansing is necessary before the procedure.

Bronchoscopy

Bronchoscopy is a procedure used to visualize or treat the respiratory tract. A bronchoscope is advanced through the nose or mouth into the trachea and bronchi. It is used to diagnose conditions such as chronic cough, shortness of breath, or lung masses, to take biopsies, or to remove foreign bodies from the airways. It also plays an important role in diagnosing infections and evaluating airway narrowing.

Laparoscopy

Laparoscopy, performed to examine the abdominal cavity and pelvic organs, is also used in minimally invasive surgical procedures. Known as “closed surgery,” this method can be used to treat many diseases such as appendicitis, gallbladder removal, cyst treatments, and endometriosis. Performed through small incisions in the abdominal wall, this method offers less pain, a shorter recovery period, and a lower risk of complications.

Capsule Endoscopy

Capsule endoscopy is performed by swallowing a small capsule containing a camera. This capsule travels through the digestive system, taking thousands of photographs and sending the data to a recording device. It is particularly suitable for examining the small intestine, which standard endoscopes cannot reach. However, it is purely a diagnostic method and cannot be used for therapeutic procedures.

ERCP (Endoscopic Retrograde Cholangiopancreatography)

ERCP is a technique used to visualize and treat the bile ducts and pancreatic ducts. An endoscope is used to reach the entrance of the bile and pancreatic ducts, and then contrast material is injected into these areas for imaging. Procedures such as gallstone removal, opening bile duct strictures, or taking biopsies from tumors are performed using this method.

Endoscopy is an important tool in modern medicine, allowing for the rapid and effective diagnosis of many diseases using non-invasive or minimally invasive methods. This provides patients with a comfortable diagnostic and treatment process.

Other Types of Endoscopy

Cystoscopy:

This is performed using a cystoscope inserted through the urethra (urinary tract) to examine the bladder and urinary tract. This method is effectively used to detect urinary tract infections, bladder stones, tumors, or causes of bleeding.

Hysteroscopy:

This is a procedure performed using a hysteroscope passed through the vagina and cervix to examine the inside of the uterus. It is used in the diagnosis and treatment of polyps, fibroids, structural abnormalities, or causes of infertility in the uterus.

Arthroscopy:

This is performed using an arthroscope inserted into the joint through small incisions to examine the inside of joints such as the knee, shoulder, and hip. It is an effective method for diagnosing and treating joint injuries, cartilage damage, and inflammation.

Laryngoscopy:

Laryngoscopy is the preferred method for visualizing the larynx (voice box) and vocal cords, performed through the mouth or nose. It is used to investigate the underlying causes of problems such as hoarseness, difficulty swallowing, or persistent cough.

Rectosigmoidoscopy:

This is a procedure performed through the rectum to evaluate the rectum and sigmoid colon, the final section of the colon. Unlike colonoscopy, it examines a shorter area and is generally preferred for checking simpler health problems.

Thoracicoscopy:

This is a procedure performed to examine the chest cavity and pleural membranes. It is preferred to evaluate chest pain, pleural diseases, or other chest cavity abnormalities.

Endoscopic Ultrasonography (EUS):

This method, which combines endoscopy and ultrasound technology, is used to evaluate the tissues surrounding internal organs and the deep structures of the organs themselves. It is particularly effective in the detailed examination of areas such as the pancreas, gallbladder, and lymph nodes.

When is Endoscopy Performed?

Endoscopy is a widely used medical procedure to diagnose and, if necessary, treat disorders of the internal organs in the body. This procedure is usually requested by specialist physicians when patients develop significant symptoms, to investigate various diseases, or to monitor previously diagnosed conditions.

The main situations in which endoscopy is preferred are:

Evaluation of Symptoms and Diagnosis

Certain complaints experienced by patients are among the most basic reasons requiring an endoscopy procedure.

Stomach Pain, Indigestion, and Reflux Complaints:

In cases of stomach pain that persists for a long time, does not improve with treatment, or worsens, chronic indigestion, heartburn, bloating, or bitter taste in the mouth, gastroscopy is performed to examine the esophagus, stomach, and duodenum. Thanks to this examination, problems such as gastritis, ulcers, or reflux disease can be detected.

Difficulty Swallowing (Dysphagia):

If you experience difficulty consuming food or liquids, a feeling of something stuck in your throat, or pain while swallowing, the presence of esophageal strictures, inflammations, or tumors should be investigated.

Unexplained Weight Loss:

Significant and unintentional weight loss occurring without any diet or lifestyle changes, especially when accompanied by other symptoms related to the digestive system, may be indicative of a significant illness and may require a detailed investigation.

Bleeding Signs

Bloody Vomiting (Hematemesis) or Black, Tar-like Stool (Melena):

These conditions indicate bleeding from the upper digestive system, such as the esophagus, stomach, or duodenum. Emergency gastroscopy may be necessary in such a case.

Fresh Blood from the Rectum (Hematochezia) or Occult Blood in the Stool:

This indicates bleeding from the lower digestive system (large intestine and rectum). Colonoscopy is usually performed to determine the source of the bleeding.

Chronic Diarrhea or Constipation:

In cases of prolonged and unexplained diarrhea or constipation, bowel diseases should be investigated with colonoscopy.

Anemia (Blood Deficiency):

Conditions such as iron deficiency anemia may be due to gastrointestinal bleeding if no other cause is found. In such cases, endoscopic examination may be necessary.

Diagnosis and Disease Monitoring

Endoscopy is an important tool in the diagnosis, staging, and evaluation of the response to treatment of digestive system diseases.

Ulcers, Gastritis, and Reflux:

Endoscopy is preferred for the definitive diagnosis and determination of the severity of these common disorders occurring in the esophagus and stomach.

Polyps and Tumors:

Endoscopy is indispensable for the visual examination of suspicious masses, polyps, or tumors in the digestive system, for biopsy analysis of their structure, and for determining whether they are benign or not. Colonoscopy, in particular, plays a critical role in detecting and removing polyps in the large intestine before they turn cancerous.

Inflammatory Bowel Diseases (IBD):

Regular endoscopic examinations are recommended for the diagnosis of inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis, to determine the extent of their spread, to monitor disease activity, and to evaluate the treatment process.

Therapeutic Use

Endoscopy is used effectively not only in the diagnostic process but also in the treatment of various diseases.

Biopsy:

Suspicious tissues are removed with the help of an endoscope and sent to the laboratory for pathological evaluation. This method helps in making an accurate diagnosis.

Polyp Removal (Polypectomy):

Polyps, especially those located in the large intestine, can be removed endoscopically before they turn into cancer with early diagnosis.

Bleeding Control:

After bleeding points in the digestive system are identified with the help of an endoscope, bleeding vessels can be controlled with methods such as coagulation, clipping, or drug injection.

Stricture Dilation:

Narrowings in the digestive system organs or esophagus can be widened using endoscopic methods such as balloon or bougie insertion, helping to resolve swallowing or digestion problems.

Stent Placement:

Stents are placed via endoscopy to remove blockages caused by tumors or other formations that cause narrowings. This is a frequently used method in the treatment of esophageal or bile duct obstructions.

Foreign Body Removal:

Objects swallowed accidentally, such as toy parts or coins, can be safely removed via endoscopy.

What You Need to Know About Endoscopy: Who Should and Shouldn’t Undergo It?

Endoscopy is one of the most frequently used methods for diagnosing and treating digestive system problems. However, this procedure may not be suitable for everyone. If you are wondering in which cases endoscopy is recommended or in which cases it carries risks, let’s look at the details together.

Who Should Undergo Endoscopy?

In general, endoscopy is quite common in individuals with digestive system complaints. However, independently of this, endoscopy is recommended for regular screening purposes in some risk groups, even if they do not have complaints.

This group can be listed as follows:

• Individuals with a family history of stomach or bowel cancer,
• People aged 50 and over,
• Those who have had stomach problems for a long time,
• Patients with a history of polyp formation.

Such factors necessitate a more proactive approach for early diagnosis. It is important for individuals in the risk group to monitor their health with regular check-ups.

Who Shouldn’t Undergo Endoscopy? Situations Where the Procedure is Contraindicated

Although endoscopy is an indispensable method for reliably and effectively diagnosing many diseases, in some specific situations it carries risks or may be considered entirely inadvisable. In such cases, it is crucial for the doctor to carefully evaluate the patient’s medical history and current condition.

Here are the main situations where endoscopy is not recommended:

Cardiac and Pulmonary Failure

In individuals with serious heart or lung diseases, sedation or anesthesia used during endoscopy may worsen the patient’s condition. In such cases, the potential benefit of the procedure may not outweigh the risks.

Bleeding Disorders

In individuals with serious bleeding problems such as hemophilia, or those who regularly take high doses of blood thinners, interventions during endoscopy (e.g., biopsy or polyp removal) can lead to uncontrollable bleeding. These complications can pose serious health problems or even a risk of death.

Active Infections (Intra-abdominal Infections)

If there is a widespread and active infection in the body, the endoscopy procedure may accelerate the spread of the infection or worsen the existing inflammation. For example, if there is inflammation of the peritoneum (peritonitis), endoscopy should be avoided.

Suspicion of Gastrointestinal Perforation

If a hole in the stomach or intestinal wall is suspected, attempting to advance the endoscope may worsen the situation and cause complications requiring emergency surgery.

Lack of Cooperation and Consciousness Problems

The safety of the procedure is compromised if the patient is unconscious, unsuitable for sedation, or agitated to the point of not cooperating during the procedure.

General Condition Deterioration and Hemodynamic Instability

Endoscopy may not be tolerated for individuals whose general health is at risk due to severe dehydration, shock, or other impairments in vital functions. In such cases, the patient’s health should be stabilized first.

In conclusion, while endoscopy is a useful diagnostic tool for many, there are certain scenarios where the procedure should not be performed, considering each individual’s general health conditions and specific circumstances. Sharing the patient’s entire medical history with their doctor and making a decision accordingly is critical for a healthy procedural process. Always seek expert advice to understand whether endoscopy is necessary and to minimize risks.

Things to Consider Before an Endoscopy

Endoscopy is an important medical procedure performed to examine the internal organs of the body in detail. To obtain the maximum benefit from this procedure and minimize the risk of possible complications, certain rules must be carefully followed before the procedure. A proper preparation process not only increases the success of the procedure but also facilitates obtaining clear images and making an accurate diagnosis.

The basic points to consider before an endoscopy are as follows:

Fasting Period:

Depending on the type of endoscopy to be performed, a fasting period of 6 to 8 hours is usually required before the procedure. It is very important not to eat or drink anything during this time. Especially in upper digestive system endoscopies, having a completely empty stomach increases the safety and effectiveness of the procedure. If your doctor permits, you can consume small amounts of water until a certain time.

Bowel Cleansing:

Before procedures such as colonoscopy performed to examine the lower digestive system, it is of great importance to completely cleanse the bowels. For this, special solutions or medications recommended by your doctor should be used. Following the instructions allows the doctor to clearly see the bowel surface and assess any potential foci. Certain dietary restrictions must also be observed before the procedure.

Information Regarding Medication Use:

Be sure to inform your doctor about all your regular medications. Some medications, such as blood thinners (e.g., aspirin or warfarin), can increase the risk of bleeding during the procedure and may need to be discontinued beforehand under your doctor’s supervision. Adjusting diabetes medications according to the fasting period is also important. Remember to get specific instructions from your doctor regarding other vital medications such as heart or blood pressure medications.

Information About Allergies:

If you have any known allergies to medications, especially if you have a sensitivity to sedation or anesthesia, be sure to inform your doctor and healthcare team. This will allow them to select appropriate medications and ensure your safety during the procedure.

Disclosure of Medical History:

You should openly share any existing health problems or previous surgeries with your doctor, such as cardiovascular disease, diabetes, high blood pressure, or asthma. This information helps the specialists performing the endoscopy procedure to take the necessary precautions.

Companion and Return Home:

If sedation or anesthesia is to be administered, you should not drive or engage in other activities requiring concentration until you have recovered after the procedure. Having a companion and planning your transportation in advance will be very helpful during this process.

Jewelry and Accessories:

Before the procedure, you may be asked to remove your jewelry (rings, earrings, necklaces), watches, contact lenses, or dentures. You can also increase your comfort by wearing comfortable, loose clothing.

By carefully following these steps, you can ensure that your endoscopy procedure is successful. Remember to always maintain open and clear communication with your doctor to ensure that the decisions you make regarding your health are based on sound principles. Remember that this is one of the most important factors in maintaining your health.

How is an Endoscopy Performed?

Endoscopy is performed by passing a device called an endoscope, which has a light and a camera at its tip, through the esophagus to examine the gastrointestinal organs such as the stomach, intestines, and colon. This procedure generally takes 10 to 30 minutes, depending on the patient’s condition.

During endoscopy, the patient is usually given a sedative anesthetic and asked to lie on their side with their knees drawn towards their abdomen. After the anesthetic takes effect, the endoscope is inserted into the throat to obtain detailed images of the targeted areas.

Before this procedure, sedatives or mild anesthetics are used to reduce the gag reflex and minimize discomfort. A plastic mouthguard is placed to keep the patient’s mouth open, and a numbing spray is applied to the throat.

After the endoscope is inserted, the patient may be asked to swallow as the device passes through the throat. A feeling of pressure may occur, but pain is usually not felt. While the endoscope is in the throat, the person may have difficulty communicating, but their breathing is not affected; they simply cannot speak.

During the procedure, a slight influx of air into the digestive system allows for better visualization of the organs. This air pressure helps the endoscope move easily and allows for clear visualization of the folds in the intestines. A slight feeling of fullness or pressure may be experienced during this time.

If necessary, tissue samples can be taken or unwanted structures such as polyps can be removed by attaching special surgical instruments to the endoscope during the procedure. When the procedure is complete, the device is gently removed from the mouth, and the procedure is terminated.

What Should Your Diet Be Like After an Endoscopy?

The dietary plan after an endoscopy depends on the type of procedure performed and the doctor’s recommendations. Generally, it is recommended to avoid eating and drinking for a few hours after the procedure. This is to allow the effects of sedation to wear off and the numbness in the throat to subside.

It is advised that the patient initially consume light and easily digestible foods. Examples include water, herbal teas, apple juice, plain crackers, or white bread. Considering the sensitivity of the digestive system, foods that cause gas and irritation should be avoided.

It will be beneficial to avoid spicy, fatty, acidic, and high-fiber foods for a while. Also, avoiding alcohol and caffeinated beverages can speed up the healing process and reduce the burden on the gastrointestinal system.
