ERCP (endoscopic retrograde cholangiopancreatography) is a procedure to examine and treat disorders of the pancreas, bile ducts, and gallbladder. ERCP is a combination of endoscopic examination and X-rays equipped with contrast dye

ERCP is performed with the help of an endoscope, which is a thin tube equipped with a camera and a light at the end. This tool will be inserted through the patient's mouth, through the esophagus, then into the stomach and duodenum, to the end of the bile duct and pancreas.

The ERCP procedure allows doctors to take pictures and see the condition of the bile ducts and pancreas in more detail. ERCP can also provide important information that cannot be obtained from other diagnostic tests, such as ultrasound, CT scan, or MRI.

Indications of Endoscopic Retrograde Cholangiopancreatography

ERCP is used to diagnose various disorders that occur in the bile duct and pancreas, such as:

  • Acute pancreatitis and chronic pancreatitis
  • Bile duct stones or narrowing of the bile duct
  • Cholecystitis or inflammation of the bile ducts
  • Pancreas divisum, a disorder that causes the pancreas to have two separate ducts
  • Tumor or cancer of the pancreas
  • Tumor or cancer of the bile duct
  • Trauma in the bile duct and pancreas

ERCP is also used as a supporting procedure for:

  • Widen the narrowed bile duct
  • Removing or destroying bile duct stones

Endoscopic Retrograde Cholangiopancreatography Warning

There are several conditions that cause a patient to be unable to undergo the ERCP procedure, namely:

  • Is pregnant
  • Has had surgery on the digestive tract which caused the bile duct to block
  • Suffering from disorders of the esophagus or digestive tract that make the ERCP procedure difficult
  • Just had a procedure using barium contrast, because barium content in the intestines can interfere with the ERCP procedure

Before Endoscopic Retrograde Cholangiopancreatography

Before the ERCP procedure, the doctor will explain to the patient the stages of the procedure to be followed, the goals, and complications that may occur. After that, the doctor will provide a form for the patient to sign, stating that the patient understands and agrees to undergo the procedure.

In addition, there are several things that patients need to do before undergoing ERCP, namely:

  • Tell your doctor if you are pregnant or think you may be pregnant.
  • Tell the doctor what medicines, supplements, or herbal products you are currently taking, especially if you are taking aspirin, anticoagulants, ibuprofen, or naproxen, because the doctor will ask the patient to stop taking these drugs for some time before ERCP.
  • Tell your doctor if you have allergies or are sensitive to certain medications, contrast dyes, iodine, or latex.
  • Tell your doctor if you have heart valve problems or have a history of blood clotting disorders.
  • Tell the doctor if you have diabetes or are taking insulin treatment, because the doctor will advise the patient to reduce the insulin dose before undergoing ERCP.

The doctor will also ask the patient to do the following before undergoing the ERCP procedure:

  • Fasting, not eating or drinking anything for 8 hours before the procedure
  • Going on a special diet for 1-2 days before the procedure
  • Inviting family members or relatives to accompany during and after the procedure, and to take them home

Endoscopic Retrograde Cholangiopancreatography Procedure

The ERCP procedure generally lasts 1–2 hours, depending on the patient's condition and the purpose of ERCP itself. The following are the steps that will be carried out by doctors in the ERCP procedure:

  • Ask the patient to remove jewelry and other accessories that could affect the procedure, and change into the hospital gown that has been provided
  • Ask the patient to lie down on the examination table or bed with the body tilted to the left or prone
  • Gives a sedative through an IV and sprays anesthetic down the throat, so the patient doesn't feel anything when the endoscope is inserted
  • Installing a dental guard to keep the patient's mouth open during ERCP
  • Insert the endoscope into the patient's mouth, then push it up to the stomach and upper duodenum
  • Pumps air into the stomach and duodenum through the endoscope to get a clearer view of the organs
  • Inserting the catheter through the endoscope, then pushing it into the bile duct and pancreatic duct
  • Injecting contrast agent through the catheter, so that the bile ducts and pancreatic ducts are seen more clearly
  • Take a series of photos with X-ray (fluoroscopy), then check for signs of narrowing or blockage in the bile ducts and pancreatic ducts

Doctors can also use ERCP for other procedures, such as:

  • Take a tissue sample (biopsy) to check for possible tumors or cancer
  • Making a small incision at the end of the pancreatic duct or bile duct in the duodenum (sphincterotomy), so that bile acids, pancreatic enzymes, or gallstones that block the duct can come out
  • Resolve narrowing or blockage along the pancreatic duct or bile duct by placing a stent

During the ERCP procedure, the patient is under sedation, but not fully asleep. The patient can still hear the doctor and may be asked to change body position during the procedure.

Because of this, the patient may feel a little uncomfortable during the procedure, for example, because they feel bloated when air is pumped into the stomach and duodenum.

After Endoscopic Retrograde Cholangiopancreatography

After the ERCP procedure is completed, the patient must undergo a recovery period of 1–2 hours until the effects of the sedatives and anesthetics wear off. The doctor will also monitor the patient's condition during the recovery process and give medication to reduce the risk of pancreatitis.

If the patient's blood pressure, heart rate and respiratory rate are stable, the patient is allowed to go home, accompanied by family or friends. However, under certain conditions, the doctor may advise the patient to stay overnight in the treatment room.

Patients who are allowed to go home must rest completely and can only return to their activities the next day. Patients also need to know some things that are normal after ERCP, namely:

  • Patients should not eat or drink anything until the effect of the anesthetic spray in the esophagus wears off completely, to reduce the risk of choking.
  • Patients do not need to continue the special diet recommended prior to ERCP.
  • Patients will feel bloated or nauseous, but it will go away after a while.
  • Patients will feel sore throat for 1-2 days after ERCP. In this phase, the patient is advised to eat soft-textured foods, such as porridge.

The doctor will discuss the results of the ERCP examination with the patient after the patient has fully recovered. If the doctor also performs a biopsy during ERCP, the results of the examination will only be known a few days later.

If the results of the ERCP show that the patient requires medical treatment, the doctor will determine the next course of treatment.

Complications of Endoscopic Retrograde Cholangiopancreatography

ERCP is a safe inspection procedure. However, some patients may experience complications after undergoing ERCP, such as:

  • Allergic reaction to sedatives
  • Inflammation of the pancreas (pancreatitis)
  • Infection of the bile duct (cholangitis) or gallbladder (cholecystitis)
  • Tissue damage due to X-ray exposure
  • Tear tear in the esophagus, stomach, small intestine, or bile

Immediately contact the doctor or the nearest hospital emergency room for emergency treatment if you experience the following symptoms:

  • Fever
  • Shiver
  • Difficulty swallowing
  • Nausea and vomiting
  • Sore throat that gets worse
  • Cough persistent (persistent)
  • chest pain
  • stomach ache
  • Bleeding (vomiting blood or having bloody stools)
