If you’re wondering about what is endoscopy, it is an imaging procedure wherein an instrument called an endoscope is used to view internal organs or tissue. It allows doctors to identify problems in the body and carry out operations without the need for large incisions. The medical professionals in Las Pinas doctors offer endoscopy to observe body parts or to help perform certain types of surgery. Here is how it works and why you might need it. 

It Is A Non-Invasive Procedure

Endoscopy works by using an endoscope — a long, thin, tube tool that is inserted into the body through a small cut or opening in the mouth, urethra, and anus to determine problems in the body

Attached at the end of the endoscope is a camera with powerful lights that allow the doctor to see clearly. The endoscope’s length and flexibility will depend on the body part to be observed. 

An endoscopy is an easy technique to look at the condition of your organs. It is non-invasive. At most, the doctor will use forceps and scissors to operate on tissues for biopsy purposes.

It Is Used To Investigate A Wide Variety Of Body Systems

The different types of endoscopy are used for investigating a wide variety of systems in the human body. These include the following:

  • Gastrointestinal tract: small intestine (enteroscopy), large intestine (sigmoidoscopy) colon (colonoscopy), esophagus, stomach, and duodenum (esophagogastroduodenoscopy), rectum (rectoscopy), and anus (anoscopy)
  • Ear: Otoscopy
  • Respiratory tract: Nose (rhinoscopy) or lower respiratory tract (bronchoscopy)
  • Urinary tract: Cystoscopy
  • Female reproductive tract (gynoscopy): Cervix (colposcopy), uterus (hysteroscopy), fallopian tubes (falloposcopy)
  • Small incisions: Abdominal or pelvis (laparoscopy), joints (arthroscopy), lungs (thoracoscopy), chest (mediastinoscopy)

Who Needs Endoscopy

Gastrointestinal pain

An endoscopy may be recommended to help your doctor identify the cause of any abnormal symptoms being experienced like difficulty swallowing, chronic stomach ache, unintentional weight loss, recurring diarrhea or indigestion, or blood in the stool. 

In addition, it may be used for the following reasons:

  • Endoscopic biopsy – removing a small tissue sample to be sent to a lab for further examination
  • Helping your doctor see inside the body while a surgical procedure is ongoing such as treating stomach ulcer, removing gallstones, or locating and removing tumors from the digestive tract 

It Does Not Require An Overnight Hospital Stay


Before an endoscopy can begin, the doctor may require you to stop consuming any food for up to 12 hours. Some drinks such as water and juice might be allowed for up to two hours before the endoscopy as well. If the type of procedure involves the gastrointestinal tract, you may be given laxatives to clear up the intestines. 

The doctor will conduct a physical examination and ask about your medical history, prior surgeries, medications, and allergies. You might be asked to stop consuming certain medications that have an impact on bleeding. 

An endoscopy is commonly performed while patients are sedated. You will be given a local anesthetic, which will block the awareness of pain. You may be awake, drowsy, or completely asleep during the procedure. Although endoscopy will typically only take about an hour to complete, you might want to plan ahead due to the aftereffects of the anesthesia.

If you receive small incisions, your doctor will close them properly. You will be given instructions on how to care for the wound. 

It Is Low Risk

Endoscopy is a non-invasive procedure, which lowers the risk of excessive bleeding and infection. However, just like any medical treatment, it carries its minor risks. These can include the following: 

  • feeling bloated after the surgery
  • mild cramping
  • a numb throat from the anesthesia
  • pain in the area checked
  • a tear in the lining of the stomach 
  • minor bleeding

Immediately report to your doctor if you encounter rare complications like dark-colored stool, shortness of breath, severe abdominal pain, or vomiting blood.
